Description

Technical Field

[0001] This application belongs to the technical field of dehydration equipment, specifically relating to a horizontal dehydrator. Background Technology

[0002] Plastic is an essential basic material widely used in various sectors of the national economy. However, improper disposal after disposal can lead to serious environmental and resource problems, necessitating the recycling and reuse of waste plastics to address plastic pollution and alleviate resource scarcity. Since waste plastics carry a large amount of pollutants such as mud and sand during recycling, repeated washing is required. Furthermore, the presence of moisture in the waste plastics can affect extrusion molding and granulation processes, necessitating the use of horizontal dewatering machines for dehydration.

[0003] Currently, horizontal dewatering machines typically include a frame, a housing mounted on the frame, a cylindrical screen inside the housing, a main shaft located inside the cylindrical screen and capable of rotating relative to the housing, and a drive assembly mounted on the frame for driving the main shaft to rotate. One end of the housing has a feed inlet, and the other end has a discharge outlet. The outer circumference of the main shaft is equipped with paddles. After waste plastic is poured into the housing through the feed inlet, the main shaft, under the action of the drive assembly, drives the paddles to rotate. This causes the waste plastic inside the housing to move circumferentially along the main shaft and towards the discharge outlet under the action of the paddles. This allows the water droplets attached to the waste plastic to separate from the waste plastic radially along the main shaft under centrifugal force, thereby achieving dewatering of the waste plastic. However, since the rotation radius of the waste plastic near the main shaft is smaller than that of the waste plastic near the cylindrical screen, the centrifugal force of the waste plastic near the main shaft is also smaller than that of the waste plastic near the cylindrical screen. This results in a poorer dewatering effect on the waste plastic near the main shaft, which in turn affects the overall dewatering effect of the waste plastic. Utility Model Content

[0004] This application provides a horizontal dewatering machine to improve the dewatering effect of the horizontal dewatering machine on waste plastics.

[0005] The technical solution adopted in this application is as follows:

[0006] A horizontal dehydrator, comprising:

[0007] The machine casing has a dehydration space inside, and the two ends of the machine casing are respectively provided with a feed inlet communicating with the dehydration space and a discharge outlet communicating with the dehydration space;

[0008] The spindle assembly includes a spindle member located inside the dehydration space and extending to the outside of the chassis, and a lever disposed on the outer peripheral surface of the spindle member. The spindle member has an air chamber inside and an exhaust port communicating with the air chamber on the outer peripheral surface of the spindle member.

[0009] An air supply component is connected to the main shaft component and is rotatable relative to the main shaft component. The air supply component is provided with a communication portion that communicates with the air chamber, and at least a portion of the communication portion extends to the outside of the chassis.

[0010] By adopting the above technical solution, when using the horizontal dewatering machine of this application, the outlet of the external air supply equipment is first connected to the connecting part via a pipeline, so that the high-pressure gas generated by the external air supply equipment enters the air chamber through the pipeline and the connecting part; then, the waste plastic is poured into the dewatering space through the feed inlet, and then the waste plastic entering the dewatering space rotates along the circumference of the main shaft component and moves towards the direction of the discharge port under the action of the main shaft component driving the paddle to rotate, so that the water droplets attached to the waste plastic are separated from the waste plastic radially from the waste plastic under the action of centrifugal force. This process achieves dehydration of waste plastics. Simultaneously, the gas entering the gas chamber is discharged through the exhaust port, causing the gas discharged through the exhaust port to move away from the main shaft component and pass through the waste plastic. This allows the waste plastic to be purged with high-pressure gas, thus separating water droplets from the waste plastic under the purging action of the high-pressure gas. This high-pressure gas compensates for the fact that the waste plastic near the main shaft component has a smaller centrifugal force, which affects the dehydration effect, thereby improving the dehydration effect of the waste plastic near the main shaft component and thus improving the dehydration effect of the horizontal dewatering machine on waste plastics.

[0011] Furthermore, by conveying high-pressure gas into the gas chamber and discharging it from the outer circumferential surface of the main shaft component, this application not only improves the dewatering effect on waste plastics close to the main shaft component, but also improves the dewatering effect on waste plastics far from the main shaft component, thereby greatly improving the dewatering effect of the horizontal dewatering machine on waste plastics.

[0012] Since at least part of the connecting part extends to the outside of the chassis, it facilitates the connection between the external air supply equipment and the connecting part, thereby improving the user experience. At the same time, it also allows the pipeline connecting the connecting part and the external air supply equipment to avoid the dehydration space, thereby ensuring the connection stability between the pipeline and the connecting part and ensuring the smooth movement of waste plastic in the dehydration space.

[0013] Optionally, the main shaft component includes a shaft cylinder located in the dehydration space, a support shaft passing through the shaft cylinder, and a connector located between the shaft cylinder and the support shaft. The air-bearing cavity is formed between the support shaft and the shaft cylinder, and the exhaust port is located in the shaft cylinder.

[0014] By adopting the above technical solution, an air-containing cavity is formed between the support shaft and the shaft cylinder, thereby reducing the difficulty of forming the air-containing cavity, which in turn reduces the manufacturing difficulty of the horizontal dewatering machine and thus reduces the manufacturing cost of the horizontal dewatering machine. Furthermore, since the support shaft passes through the shaft cylinder, it can increase the support stability of the support shaft on the shaft cylinder, thereby increasing the stability of the main shaft component. On the other hand, it can also increase the structural strength of the main shaft component, thereby ensuring the service life of the horizontal dewatering machine.

[0015] Optionally, the connecting member includes a sealing plate located at one end of the shaft cylinder and used to seal the gap between the shaft cylinder and the support shaft, and a connecting plate located in the middle of the shaft cylinder. The connecting plate is provided with an air hole, and the end of the shaft cylinder away from the sealing plate forms the opening of the air-containing cavity. The air supply component is used to block the opening of the air-containing cavity.

[0016] By adopting the above technical solution, the sealing plate is used to seal the gap between the shaft and the support shaft, thereby increasing the sealing performance of the gas chamber to a certain extent. This ensures that the high-pressure gas has a relatively high pressure when it is discharged through the exhaust port, thus improving the purging effect of the high-pressure gas on the waste plastic. Furthermore, the connecting plate has an air passage, allowing the high-pressure gas entering the gas chamber to pass through the air passage and flow axially along the main shaft component, thus distributing the high-pressure gas more evenly and further improving the dewatering effect of the horizontal dewatering machine on the waste plastic. Since the end of the shaft away from the sealing plate forms the opening of the gas chamber, the air supply component is used to seal the opening. This reduces the installation difficulty of the air supply component, improving the production efficiency of the horizontal dewatering machine, and further enhances the sealing performance of the gas chamber, ensuring the pressure of the high-pressure gas when it is discharged through the exhaust port, thereby further improving the purging effect of the high-pressure gas on the waste plastic.

[0017] Optionally, the air supply component includes an end cap sleeved on the support shaft, the end cap having a sealing cylinder extending into the shaft cylinder, and the communicating portion being disposed on the end cap.

[0018] By adopting the above technical solution, since the end cover is sleeved on the support shaft and the end cover has a sealing cylinder that extends into the shaft cylinder, on the one hand, the end cover can be used to seal the gap between the shaft cylinder and the support shaft to increase the sealing performance of the air chamber, and on the other hand, the sealing cylinder can be used to support the shaft cylinder to increase the stability of the shaft cylinder, thereby further increasing the stability of the main shaft component.

[0019] Optionally, the end cap has a connecting cylinder sleeved outside the support shaft, the connecting cylinder and the sealing cylinder are located at the same end of the end cap, and the connecting cylinder is located inside the sealing cylinder.

[0020] By adopting the above technical solution, since the end cover has a connecting cylinder sleeved outside the support shaft, it can increase the connection area between the end cover and the support shaft to increase the support effect of the support shaft on the end cover. On the other hand, it can also increase the sealing between the support shaft and the end cover to further increase the sealing of the air chamber. Since the connecting cylinder and the sealing cylinder are located at the same end of the end cover, the connecting cylinder can be hidden inside the shaft cylinder, so as to facilitate the miniaturization design of the horizontal dewatering machine.

[0021] Optionally, a first sealing ring is provided between the sealing cylinder and the shaft cylinder;

[0022] And / or, a second sealing ring is provided between the connecting cylinder and the support shaft.

[0023] By adopting the above technical solution, since a first sealing ring is provided between the sealing cylinder and the shaft cylinder, the gap between the sealing cylinders can be sealed by the first sealing ring, thereby increasing the sealing performance between the sealing cylinder and the shaft cylinder, thereby further increasing the sealing performance of the gas chamber, and further ensuring the pressure of the high-pressure gas when it is discharged through the exhaust hole, so as to further improve the purging effect of the high-pressure gas on the waste plastic.

[0024] Because a second sealing ring is provided between the connecting cylinder and the support shaft, the gap between the connecting cylinder and the support shaft can be sealed by the second sealing ring, thereby increasing the sealing performance between the connecting cylinder and the support shaft, which in turn increases the sealing performance of the gas chamber, and further ensures the pressure of the high-pressure gas when it is discharged through the exhaust port, so as to further improve the purging effect of the high-pressure gas on the waste plastic.

[0025] Optionally, the horizontal dehydrator further includes a drive assembly, which includes a motor, a drive wheel located on the output shaft of the motor, a driven wheel located at the end of the main shaft component, and a belt for connecting the drive wheel and the driven wheel. The air supply component is located at the end of the machine housing away from the drive assembly.

[0026] By adopting the above technical solution, when the main spindle component is driven to rotate, the motor is started so that the output shaft of the motor drives the drive wheel to rotate. The drive wheel drives the driven wheel to rotate under the action of the belt, so that the driven wheel drives the main spindle component to rotate, thereby realizing the drive component driving the main spindle component to rotate.

[0027] Because the air supply component is located at the end of the chassis away from the drive component, it can avoid interfering with the drive component, thus facilitating the connection between the connection part and the external air supply equipment through the pipeline. At the same time, it can also avoid the pipeline from interfering with the belt and causing pipeline damage, thereby improving the user experience.

[0028] Optionally, the driven wheel has a central hole sleeved on the outside of the main shaft component, the diameter of the central hole gradually decreases in the direction close to the air supply component, a fixing sleeve is provided between the main shaft component and the central hole, the outer diameter of the fixing sleeve gradually decreases in the direction close to the air supply component, and a fixing cover is provided at the end of the main shaft component for applying pressure to the fixing sleeve toward the side where the air supply component is located, and a fixing bolt threaded to the main shaft component passes through the fixing cover.

[0029] By adopting the above technical solution, when installing the driven wheel, the driven wheel is first installed on the end of the spindle component so that the center hole is fitted outside the spindle component. Then, the fixing sleeve is installed so that it is inserted between the spindle component and the center hole. Then, the fixing cover and fixing bolt are installed so that the fixing bolt is threaded to the end of the spindle component. The fixing bolt is then tightened so that the bolt head of the fixing bolt exerts a pressing force on the fixing cover facing the fixing sleeve, thereby causing the fixing cover to press against the fixing sleeve, so that the fixing sleeve continues to move into the center hole. Finally, the outer circumferential surface of the fixing sleeve abuts against the hole wall of the center hole, and the inner circumferential surface of the fixing sleeve abuts against the outer circumferential surface of the spindle component, thus completing the fixing of the driven wheel.

[0030] Since the diameter of the central hole gradually decreases along the direction close to the air supply component, and the outer diameter of the fixed sleeve gradually decreases along the direction close to the air supply component, the fixed sleeve can be pressed by the fixed cover to fix the driven wheel to the main shaft component, thereby reducing the difficulty of installing the driven wheel and increasing the connection stability between the driven wheel and the main shaft component.

[0031] Optionally, the chassis is provided with a mounting hole for the end of the spindle component to pass through, and a seal is provided at the mounting hole for the spindle component.

[0032] By adopting the above technical solution, since the chassis is provided with mounting holes for the ends of the spindle components to pass through, and a sealing element is provided at the mounting holes and fitted onto the spindle components, the gap between the mounting holes and the spindle components can be sealed by the sealing element, thereby increasing the sealing performance between the spindle components and the chassis. This prevents water from overflowing to the outside of the chassis through the mounting holes, ensuring the cleanliness of the horizontal dewatering machine. At the same time, it also prevents dust from entering the dewatering space through the gap between the mounting holes and the spindle components, thus preventing the waste plastics after cleaning from being recontaminated.

[0033] Optionally, the chassis is provided with a sealing seat, at least a portion of which is located in the mounting hole. The sealing element is installed on the sealing seat. The sealing seat has a retaining edge on the side near the dehydration space, and a limit cover is provided on the side of the sealing seat away from the dehydration space. The limit cover has a limiting rib that abuts against the sealing element.

[0034] By adopting the above technical solution, since the seal is installed on the sealing seat, and the sealing seat has a retaining edge on the side near the dehydration space, the installation difficulty of the seal can be reduced, thereby improving the installation efficiency of the seal and thus increasing the production efficiency of the horizontal dehydrator. On the other hand, the sealing performance of the seal can also be increased to ensure the sealing effect of the seal on the gap between the mounting hole and the main shaft component. Furthermore, since a limit cover is provided on the side of the sealing seat away from the dehydration space, and the limit cover has a limiting rib that abuts against the seal, the limit cover and the limiting rib can be used to limit the seal, thereby further increasing the stability of the seal and further increasing the sealing effect of the seal on the gap between the mounting hole and the main shaft component.

[0035] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0036] 1. The horizontal dewatering machine of this application includes a casing, a main shaft assembly, and an air supply component. The casing has a dewatering space inside, and the two ends of the casing are respectively provided with a feed inlet communicating with the dewatering space and a discharge outlet communicating with the dewatering space. The main shaft assembly includes a main shaft component located inside the dewatering space and extending to the outside of the casing, and a lever provided on the outer peripheral surface of the main shaft component. An air chamber is formed inside the main shaft component, and an exhaust hole communicating with the air chamber is provided on the outer peripheral surface of the main shaft component. The air supply component is connected to the main shaft component and can rotate relative to the main shaft component. The air supply component is provided with a connecting part communicating with the air chamber. At least part of the connecting part extends to the outside of the casing, so that high-pressure gas can be supplied to the air chamber through the connecting part by an external air supply device. When the high-pressure gas in the air chamber is discharged through the exhaust hole, it blows the waste plastic, thereby improving the dewatering effect on the waste plastic.

[0037] 2. The main shaft component in this application includes a shaft cylinder located in the dehydration space, a support shaft passing through the shaft cylinder, and a connecting piece located between the shaft cylinder and the support shaft. An air chamber is formed between the support shaft and the shaft cylinder, and an exhaust port is located in the shaft cylinder. This reduces the difficulty of forming the air chamber, thereby reducing the manufacturing difficulty of the horizontal dehydrator. It also increases the support stability of the support shaft on the shaft cylinder, thereby increasing the stability of the main shaft component. Furthermore, it increases the structural strength of the main shaft component, thus ensuring the service life of the horizontal dehydrator.

[0038] 3. The connecting component in this application includes a sealing plate located at one end of the shaft cylinder for sealing the gap between the shaft cylinder and the support shaft, and a connecting plate located in the middle of the shaft cylinder. The connecting plate is provided with an air passage. The end of the shaft cylinder away from the sealing plate forms the opening of the air-containing chamber. The air supply component is used to block the opening of the air-containing chamber. This can, on the one hand, increase the sealing performance of the air-containing chamber to a certain extent, so as to ensure that the high-pressure gas can have a relatively high pressure when it is discharged through the exhaust hole, thereby improving the purging effect of the high-pressure gas on the waste plastic. On the other hand, it reduces the installation difficulty of the air supply component, thereby improving the production efficiency of the horizontal dewatering machine. Furthermore, it can further improve the sealing performance of the air-containing chamber, so as to further ensure the pressure of the high-pressure gas when it is discharged through the exhaust hole, thereby further improving the purging effect of the high-pressure gas on the waste plastic.

[0054] Reference Figures 1 to 7 A horizontal dewatering machine is disclosed, comprising a casing 1, a main shaft assembly 2, and an air supply component. The casing 1 has a dewatering space inside, and an inlet 11 communicating with the dewatering space and an outlet 12 communicating with the dewatering space are respectively provided at both ends of the casing 1. The main shaft assembly 2 includes a main shaft member 21 located inside the dewatering space and extending to the outside of the casing 1, and a lever 22 provided on the outer peripheral surface of the main shaft member 21. An air chamber 215 is formed inside the main shaft member 21, and an exhaust hole 214 communicating with the air chamber 215 is provided on the outer peripheral surface of the main shaft member 21. The air supply component is connected to the main shaft member 21 and can rotate relative to the main shaft member 21. The air supply component is provided with a connecting part 31 communicating with the air chamber 215, and at least a portion of the connecting part 31 extends to the outside of the casing 1.

[0055] It is understood that the interior of the casing 1 is hollow and forms a dehydration space. The feed inlet 11 is located at one end of the casing 1, and the discharge outlet 12 is located at the other end of the casing 1. Multiple paddles 22 are provided, and the multiple paddles 22 are spaced apart along the axial and circumferential directions of the main shaft component 21. Multiple exhaust holes 214 are spaced apart along the circumferential and axial directions of the main shaft component 21. The air supply component is located inside the casing 1.

[0056] When using the horizontal dewatering machine of this application, firstly, the air outlet of the external air supply device is connected to the connecting part 31 via a pipeline, so that the high-pressure gas generated by the external air supply device enters the air chamber 215 through the pipeline and the connecting part 31; then, waste plastic is poured into the dewatering space through the feed inlet 11, and then the waste plastic entering the dewatering space rotates along the circumference of the main shaft component 21 and moves towards the direction of the discharge port 12 under the action of the main shaft component 21 driving the paddle 22 to rotate, thereby causing the water droplets attached to the waste plastic to separate from the waste plastic radially from the waste plastic under the action of centrifugal force, so as to achieve the dewatering of waste plastic. The plastic is dehydrated; at the same time, the high-pressure gas entering the gas chamber 215 is also discharged through the exhaust port 214, which causes the high-pressure gas discharged through the exhaust port 214 to move away from the main shaft component 21 and pass through the waste plastic, so as to realize the use of high-pressure gas to blow the waste plastic, thereby separating the water droplets from the waste plastic under the blowing action of the high-pressure gas. This is to use high-pressure gas to compensate for the situation where the waste plastic near the main shaft component 21 is affected by the smaller centrifugal force, thereby improving the dehydration effect of the waste plastic near the main shaft component 21, thus improving the dehydration effect of the horizontal dewatering machine on waste plastic.

[0057] Furthermore, by supplying high-pressure gas into the gas chamber 215 and discharging the high-pressure gas from the outer peripheral surface of the main shaft component 21, this application not only improves the dehydration effect on waste plastics close to the main shaft component 21, but also improves the dehydration effect on waste plastics far from the main shaft component 21, thereby greatly improving the dehydration effect of the horizontal dewatering machine on waste plastics.

[0058] Since at least a portion of the connecting part 31 extends to the outside of the casing 1, it is possible to facilitate the connection between the external air supply equipment and the connecting part 31, thereby improving the user experience. At the same time, it also allows the pipeline connecting the connecting part 31 and the external air supply equipment to avoid the dehydration space, thereby ensuring the connection stability between the pipeline and the connecting part 31 and ensuring the smooth movement of waste plastic in the dehydration space.

[0059] It should be noted that the "external gas supply equipment" mentioned above can be an air pump, or it can be an air compressor or other equipment that can provide high-pressure gas.

[0060] In a preferred embodiment, refer to Figure 2The machine casing 1 includes a feeding section, a dewatering section, and a discharging section, which are arranged sequentially along the axial direction of the main shaft component 21. The feeding port 11 is located at the top of the feeding section to facilitate the pouring of waste plastic into the dewatering space. The discharging port 12 is located at the side of the discharging section to extend the residence time of the waste plastic inside the machine casing 1 as much as possible, thereby further improving the dewatering effect on the waste plastic. The dewatering section is provided with a dewatering port 13, and the machine casing 1 is provided with a screen located at the dewatering port 13 so that water droplets in the waste plastic can be discharged to the outside of the dewatering space through the screen.

[0061] Furthermore, refer to Figure 2 The paddle 22 includes a drive paddle and a discharge paddle. The drive paddle is located in the feeding section and the dewatering section, and the drive paddle is inclined so that when the drive paddle rotates with the main shaft component 21, the drive paddle can drive the waste plastic from the feeding port 11 toward the discharge port 12. The discharge paddle is located inside the discharge section, and when the discharge paddle 22 rotates with the main shaft component 21, it can drive the waste plastic that has moved to the processing discharge section to the discharge port 12 so that the dewatered waste plastic is discharged through the discharge port 12.

[0062] Furthermore, refer to Figure 2 The horizontal dewatering machine also includes a frame 4, and a housing 1 is fixedly connected to the frame 4 and located above the frame 4, so as to use the frame 4 to support the housing 1 and increase the stability of the horizontal dewatering machine.

[0063] Furthermore, the screen edge is provided with a pressure plate, which is fixedly connected to the housing 1 by bolts, so that the screen can be disassembled by removing the pressure plate, thereby facilitating the replacement and cleaning of the screen.

[0064] Furthermore, refer to Figure 2 , Figure 6 and Figure 7The machine casing 1 has a water receiving shell 14 and a protective shell 15 located above the water receiving shell 14. Both the water receiving shell 14 and the protective shell 15 are located outside the dewatering section. The water receiving shell 14 is fixedly connected to the frame 4, and the bottom wall of the water receiving shell 14 is inclined downward from the feed inlet 11 to the discharge outlet 12, so that the water passing through the screen enters the water receiving shell 14 and flows along the bottom wall of the water receiving shell 14 toward the end where the discharge outlet 12 is located. A drain pipe is provided at the end of the water receiving shell 14 near the discharge outlet 12 so that the water entering the water receiving shell 14 can be discharged through the drain pipe; the protective shell 15 covers... The frame includes an end plate, a top plate fixed to the top of the end plate by bolts, and side plates on both sides of the top plate. The top end of the side plate is fixed to the top plate by a buckle. The frame 4 is provided with a limiting plate at the top of the water receiving shell 14. The limiting plate has a C-shaped cross section. The bottom end of the side plate is located inside the limiting plate, so as to limit the bottom end of the side plate, so as to facilitate the disassembly and assembly of the side plate, thereby facilitating the disassembly and assembly of the screen. The inner side of the limiting plate is provided with a drainage notch, so that water entering the bottom of the side plate can enter the water receiving shell 14 through the drainage notch.

[0065] This application does not specifically limit the structure of the main shaft component 21; preferably, refer to... Figure 2 , Figure 5 , Figure 6 and Figure 7 The main shaft component 21 includes a shaft cylinder 211 located in the dehydration space, a support shaft 212 passing through the shaft cylinder 211, and a connector 213 located between the shaft cylinder 211 and the support shaft 212. An air chamber 215 is formed between the support shaft 212 and the shaft cylinder 211, and an exhaust port 214 is provided in the shaft cylinder 211.

[0066] It is understood that the support shaft 212 and the shaft cylinder 211 are coaxially arranged, the length of the support shaft 212 is greater than the length of the shaft cylinder 211, both ends of the support shaft 212 are located outside the shaft cylinder 211, and both ends of the support shaft 212 extend to the outside of the housing 1. The connector 213 is located inside the shaft cylinder 211 and is used to connect the support shaft 212 and the shaft cylinder 211. The paddle 22 is located on the outer circumferential surface of the shaft cylinder 211. The exhaust hole 214 penetrates the shaft cylinder 211 in the wall thickness direction so that the high pressure gas can be discharged to the outside of the gas chamber 215 through the exhaust hole 214.

[0067] Since an air-filled cavity 215 is formed between the support shaft 212 and the shaft cylinder 211, the difficulty of forming the air-filled cavity 215 is reduced, thereby reducing the manufacturing difficulty of the horizontal dewatering machine and thus reducing the manufacturing cost of the horizontal dewatering machine. Furthermore, since the support shaft 212 passes through the shaft cylinder 211, it can increase the support stability of the support shaft 212 on the shaft cylinder 211, thereby increasing the stability of the main shaft component 21. On the other hand, it can also increase the structural strength of the main shaft component 21, thereby ensuring the service life of the horizontal dewatering machine.

[0068] Preferably, the support shaft 212 is fitted with bearings at both ends outside the housing 1, and the frame 4 is provided with bearing seats at both ends of the housing 1, with the two bearings located in the two bearing seats respectively, to increase the stability of the spindle component 21.

[0069] This application does not specifically limit the structure of connector 213; preferably, refer to... Figure 5 The connecting member 213 includes a sealing plate 216 located at one end of the shaft cylinder 211 and used to seal the gap between the shaft cylinder 211 and the support shaft 212, and a connecting plate 217 located in the middle of the shaft cylinder 211. The connecting plate 217 is provided with an air hole 218. The end of the shaft cylinder 211 away from the sealing plate 216 forms the opening of the air chamber 215. The air supply component is used to block the opening of the air chamber 215.

[0070] Understandably, the sealing plate 216 has a hole structure for the support shaft 212 to pass through. The inner circumferential surface of the sealing plate 216 is fixedly connected to the support shaft 212, and the outer circumferential surface of the sealing plate 216 is fixedly connected to the inner wall of the shaft cylinder 211. The connecting plate 217 is located in the middle of the shaft cylinder 211 along its length, that is, the connecting plate 217 is located at the non-end of the shaft cylinder 211. The connecting plate 217 also has a hole structure for the support shaft 212 to pass through. The inner circumferential surface of the connecting plate 217 is fixedly connected to the support shaft 212, and the outer circumferential surface of the connecting plate 217 is fixedly connected to the shaft cylinder 211.

[0071] Since the sealing plate 216 is used to seal the gap between the shaft cylinder 211 and the support shaft 212, it can increase the sealing performance of the gas chamber 215 to a certain extent, so as to ensure that the high pressure gas can have a relatively high pressure when it is discharged through the exhaust port 214, thereby improving the purging effect of the high pressure gas on the waste plastic.

[0072] Furthermore, since the connecting plate 217 is provided with an air passage 218, the high-pressure gas entering the air chamber 215 can pass through the air passage 218 and the connecting plate 217 and flow axially in the main shaft component 21, thereby making the high-pressure gas distribution more uniform as much as possible, so as to further improve the dewatering effect of the horizontal dewatering machine on waste plastics. Since the end of the shaft cylinder 211 away from the sealing plate 216 forms the opening of the air chamber 215, the air supply component is used to seal the opening of the air chamber 215, thereby reducing the installation difficulty of the air supply component and improving the production efficiency of the horizontal dewatering machine. On the other hand, it can also further improve the sealing of the air chamber 215, so as to further ensure the pressure when the high-pressure gas is discharged through the exhaust port 214, thereby further improving the purging effect of the high-pressure gas on waste plastics.

[0073] Preferably, multiple connecting plates 217 are arranged at intervals along the axial direction of the shaft cylinder 211, and each connecting plate 217 is provided with an air hole 218 to increase the connection stability between the support shaft 212 and the shaft cylinder 211, and at the same time, it can also increase the support effect of the support shaft 212 on the shaft cylinder 211, thereby increasing the structural strength of the main shaft component 21.

[0074] In other embodiments, the connector 213 may also include a rod-shaped structure, with multiple rod-shaped structures spaced apart circumferentially and axially along the support shaft 212, and one end of the rod-shaped structure being fixedly connected to the support shaft 212, and the other end of the rod-shaped structure being fixedly connected to the inner wall of the shaft cylinder 211.

[0075] This application does not specifically limit the structure of the gas supply component; however, preferred options are described below. Figure 2 and Figure 3 The air supply component includes an end cap 3 sleeved on the support shaft 212. The end cap 3 has a sealing cylinder 32 extending into the shaft cylinder 211, and a connecting part 31 is provided on the end cap 3.

[0076] It is understood that the end cover 3 has a hole structure for the support shaft 212 to pass through. The end cover 3 is fixedly connected to the inner wall of the housing 1 so that the main shaft component 21 can rotate relative to the end cover 3 when it rotates. The connecting part 31 is fixedly connected to the end cover 3, and the end cover 3 is provided with a hole structure corresponding to the connecting part 31.

[0077] Since the end cap 3 is sleeved on the support shaft 212 and the end cap 3 has a sealing cylinder 32 extending into the shaft cylinder 211, the end cap 3 can seal the gap between the shaft cylinder 211 and the support shaft 212 to increase the sealing performance of the air chamber 215. On the other hand, the sealing cylinder 32 can support the shaft cylinder 211 to increase the stability of the shaft cylinder 211, thereby further increasing the stability of the main shaft component 21.

[0078] This application does not specify the method of fixing the end cover 3 to the chassis 1. It can be fixed by bolts, or it can be fixed to the chassis 1 by other methods such as adhesive or snap-fit.

[0079] Furthermore, refer to Figure 2 and Figure 3 The end cap 3 has a connecting cylinder 33 sleeved outside the support shaft 212. The connecting cylinder 33 and the sealing cylinder 32 are located at the same end of the end cap 3, and the connecting cylinder 33 is located inside the sealing cylinder 32.

[0080] It is understandable that the connecting part 31 is located between the sealing cylinder 32 and the connecting cylinder 33.

[0081] Since the end cap 3 has a connecting sleeve 33 sleeved outside the support shaft 212, it can increase the connection area between the end cap 3 and the support shaft 212 to increase the support effect of the support shaft 212 on the end cap 3. On the other hand, it can also increase the sealing between the support shaft 212 and the end cap 3 to further increase the sealing of the air chamber 215.

[0082] Furthermore, since the connecting cylinder 33 and the sealing cylinder 32 are located at the same end of the end cover 3, the connecting cylinder 33 can be hidden inside the shaft cylinder 211, thereby facilitating the miniaturization design of the horizontal dewatering machine.

[0083] Furthermore, refer to Figure 2 and Figure 3 A first sealing ring 321 is provided between the sealing cylinder 32 and the shaft cylinder 211.

[0084] It is understandable that the first sealing ring 321 is sleeved on the outside of the sealing cylinder 32, and the outer peripheral surface of the first sealing ring 321 contacts the inner peripheral surface of the shaft cylinder 211.

[0085] Since a first sealing ring 321 is provided between the sealing cylinder 32 and the shaft cylinder 211, the gap between the sealing cylinders 32 can be sealed by the first sealing ring 321, thereby increasing the sealing performance between the sealing cylinder 32 and the shaft cylinder 211, thereby further increasing the sealing performance of the gas chamber 215, and further ensuring the pressure when the high-pressure gas is discharged through the exhaust port 214, so as to further improve the purging effect of the high-pressure gas on the waste plastic.

[0086] Preferably, multiple first sealing rings 321 are spaced apart along the axial direction of the sealing cylinder 32 to increase the sealing effect of the first sealing rings 321 on the gap between the sealing cylinder 32 and the shaft cylinder 211; and multiple first annular grooves are provided on the outer circumferential surface of the sealing cylinder 32, with each first annular groove corresponding to a first sealing ring 321, and each first sealing ring 321 located in its corresponding first annular groove. This can increase the stability of the first sealing rings 321 on the one hand, and increase the contact area between the first sealing rings 321 and the sealing cylinder 32 on the other hand, so as to further increase the sealing effect of the first sealing rings 321 on the gap between the sealing cylinder 32 and the shaft cylinder 211.

[0087] Furthermore, refer to Figure 2 and Figure 3 A second sealing ring 331 is provided between the connecting cylinder 33 and the support shaft 212.

[0088] It is understandable that the second sealing ring 331 is sleeved on the outside of the support shaft 212, and the outer peripheral surface of the second sealing ring 331 contacts the inner peripheral surface of the connecting cylinder 33.

[0089] Since a second sealing ring 331 is provided between the connecting cylinder 33 and the support shaft 212, the gap between the connecting cylinder 33 and the support shaft 212 can be sealed by the second sealing ring 331, thereby increasing the sealing performance between the connecting cylinder 33 and the support shaft 212, thereby further increasing the sealing performance of the gas chamber 215, and further ensuring the pressure when the high-pressure gas is discharged through the exhaust port 214, so as to further improve the purging effect of the high-pressure gas on the waste plastic.

[0090] Preferably, multiple second sealing rings 331 are spaced apart along the axial direction of the connecting cylinder 33 to increase the sealing effect of the second sealing rings 331 on the gap between the support shaft 212 and the connecting cylinder 33; and multiple second annular grooves are provided on the outer circumferential surface of the support shaft 212, with each second annular groove corresponding to a second sealing ring 331, and each second sealing ring 331 located in its corresponding second annular groove. This increases the stability of the second sealing rings 331 and the contact area between the second sealing rings 331 and the support shaft 212, thereby further increasing the sealing effect of the second sealing rings 331 on the gap between the connecting cylinder 33 and the support shaft 212.

[0091] In other embodiments, the gas supply component may further include an annular plate sleeved on the outside of the shaft cylinder 211, the connecting part 31 being a tubular structure fixedly connected to the annular plate, and the annular plate having a hole structure corresponding to the tubular structure. The shaft cylinder 211 is provided with a docking hole that can communicate with the tubular structure, so that when the shaft cylinder 211 rotates, the annular plate and the shaft cylinder 211 rotate relative to each other, thereby ensuring the smooth rotation of the shaft cylinder 211. At the same time, it also allows the high-pressure gas generated by the external gas supply device to enter the gas chamber 215 through the connecting part 31 and the docking hole.

[0092] In other embodiments, the main shaft component 21 support shaft 212 can also be provided in two sections, with the two support shaft sections 212 located at both ends of the shaft cylinder 211 and fixedly connected to the shaft cylinder 211 by the connector 213, so as to reduce the weight of the main shaft component 21 and reduce the production cost of the horizontal dewatering machine.

[0093] In a preferred embodiment, refer to Figure 1 and Figure 6 The horizontal dehydrator also includes a drive assembly 5, which includes a motor, a drive wheel located on the output shaft of the motor, a driven wheel 51 located at the end of the main shaft component 21, and a belt for connecting the drive wheel and the driven wheel 51. The air supply component is located at the end of the casing 1 away from the drive assembly 5.

[0094] It is understood that the motor is fixedly connected to the frame 4, the drive wheel is coaxially fixedly connected to the output shaft of the motor, the belt is sleeved on the outside of the drive wheel and the driven wheel 51, and the belt is in a tensioned state so that the drive wheel drives the driven wheel 51 to rotate through the belt; the driven wheel 51 is located outside the housing 1, and the driven wheel 51 is located on the support shaft 212.

[0095] When the main spindle component 21 is driven to rotate, the motor is started so that the output shaft of the motor drives the drive wheel to rotate. The drive wheel drives the driven wheel 51 to rotate under the action of the belt, so that the driven wheel 51 drives the main spindle component 21 to rotate, thereby realizing the drive component 5 driving the main spindle component 21 to rotate.

[0096] Since the air supply component is located at the end of the chassis 1 away from the drive component 5, it can avoid the drive component 5, so as to facilitate the connection of the connecting part 31 with the external air supply equipment by means of the pipeline. At the same time, it can also avoid the pipeline from interfering with the belt and causing pipeline damage, thereby improving the user experience.

[0097] This application does not specify the connection method between the driven wheel 51 and the support shaft 212. Preferably, refer to... Figure 2 and Figure 4 The driven wheel 51 has a central hole sleeved on the outside of the main shaft member 21. The diameter of the central hole gradually decreases in the direction close to the air supply member. A fixing sleeve 511 is provided between the main shaft member 21 and the central hole. The outer diameter of the fixing sleeve 511 gradually decreases in the direction close to the air supply member. A fixing cover 512 is provided at the end of the main shaft member 21 for applying pressure to the fixing sleeve 511 toward the side where the air supply member is located. A fixing bolt 513 threadedly connected to the main shaft member 21 passes through the fixing cover 512.

[0098] It is understandable that the wall of the central hole is inclined, the outer wall of the fixing sleeve 511 is inclined, and the inclination angle of the central hole wall is equal to the inclination angle of the outer wall of the fixing sleeve 511; the fixing cover 512 is located on the side of the driven wheel 51 away from the air supply component, the end of the support shaft 212 is provided with a threaded hole, the fixing bolt 513 is threaded into the threaded hole, and the bolt head of the fixing bolt 513 is located on the side of the fixing cover 512 away from the air supply component.

[0099] When installing the driven wheel 51, first install the driven wheel 51 on the end of the support shaft 212 so that the center hole is fitted onto the outside of the support shaft 212. Then install the fixing sleeve 511 so that the fixing sleeve 511 is inserted between the support shaft 212 and the center hole. Then install the fixing cover 512 and the fixing bolt 513 so that the fixing bolt 513 is threaded onto the end of the support shaft 212. Then tighten the fixing bolt 513 so that the bolt head of the fixing bolt 513 exerts a pressing force on the side of the fixing cover 512 facing the fixing sleeve 511, thereby causing the fixing cover 512 to press the fixing sleeve 511, so that the fixing sleeve 511 continues to move into the center hole. Finally, the outer circumferential surface of the fixing sleeve 511 abuts against the hole wall of the center hole, and the inner circumferential surface of the fixing sleeve 511 abuts against the outer circumferential surface of the main shaft component 21, thus completing the fixing of the driven wheel 51.

[0100] Since the diameter of the central hole gradually decreases along the direction close to the air supply component, and the outer diameter of the fixed sleeve 511 gradually decreases along the direction close to the air supply component, the fixed sleeve 511 can be pressed by the fixed cover 512 to achieve the fixed connection of the driven wheel 51 to the main shaft component 21 by the fixed sleeve 511, thereby reducing the installation difficulty of the driven wheel 51 and increasing the connection stability between the driven wheel 51 and the main shaft component 21.

[0101] Preferably, the fixing sleeve 511 and the support shaft 212 are respectively provided with keyways, and a flat key extending into the two keyways is provided between the fixing sleeve 511 and the support shaft 212, so as to limit the relative rotation of the fixing sleeve 511 and the support shaft 212 by using the flat key, thereby increasing the connection stability between the fixing sleeve 511 and the support shaft 212. At the same time, the fixing cover 512 can also limit the flat key to increase the stability of the flat key.

[0102] Preferably, the fixing sleeve 511 is provided with a partition groove that extends axially along the support shaft 212, so that the fixing sleeve 511 can deform under the compression of the fixing cover 512, thereby changing the diameter of the fixing sleeve 511. This causes the inner circumferential surface of the fixing sleeve 511 to abut against the outer circumferential surface of the support shaft 212, while the outer circumferential surface of the fixing sleeve 511 abuts against the wall of the central hole, further increasing the fixing effect of the fixing sleeve 511 on the driven wheel 51.

[0103] The better one is to refer to Figure 2 and Figure 4 The support shaft 212 is fitted with a retaining ring 514 that cooperates with the shoulder stop of the support shaft 212. The retaining ring 514 is located on the side of the driven wheel 51 and the fixed sleeve 511 near the air supply component, so that the retaining ring 514 can limit the driven wheel 51 and the fixed sleeve 511, thereby further increasing the fixing stability of the driven wheel 51.

[0104] This application does not specifically limit the structure of the fixed cover 512; preferably, refer to... Figure 4 The fixing cover 512 has an edge on the side near the air supply component. The edge extends circumferentially along the fixing cover 512 and is used to contact the fixing cover 512. Under the action of the fixing bolt 513, the edge can apply a compressive force to the fixing sleeve 511 towards the side where the air supply component is located, so as to ensure the compressive effect of the fixing cover 512 on the fixing sleeve 511. In other embodiments, the fixing cover 512 can also be a flat plate structure or other structures that can use the fixing bolt 513 to compress the fixing sleeve 511.

[0105] In a preferred embodiment, refer to Figure 3 The housing 1 is provided with a mounting hole for the end of the spindle component 21 to pass through, and a seal 163 is provided at the mounting hole and fitted onto the spindle component 21.

[0106] Understandably, the diameter of the mounting hole is larger than the diameter of the support shaft 212 so that the end of the support shaft 212 can extend to the outside of the chassis 1 through the mounting hole.

[0107] Since the chassis 1 is provided with a mounting hole for the end of the spindle component 21 to pass through, and a seal 163 is provided at the mounting hole and fitted onto the spindle component 21, the seal 163 can be used to seal the gap between the mounting hole and the support shaft 212, thereby increasing the sealing between the support shaft 212 and the chassis 1. This prevents water from overflowing to the outside of the chassis 1 through the mounting hole, ensuring the cleanliness of the horizontal dewatering machine. At the same time, it also prevents dust from entering the dewatering space through the gap between the mounting hole and the support shaft 212, thus preventing the waste plastic after cleaning from being recontaminated.

[0108] Furthermore, refer to Figure 3 The casing 1 is provided with a sealing seat 16, at least a portion of which is located in the mounting hole. The sealing element 163 is installed on the sealing seat 16. The side of the sealing seat 16 near the dehydration space has a retaining edge. The side of the sealing seat 16 away from the dehydration space is provided with a limit cover 161. The limit cover 161 is provided with a limit rib 162 that abuts against the sealing element 163.

[0109] It is understood that the sealing seat 16 is provided with a hole structure for the support shaft 212 to pass through, and the sealing element 163 is located in the hole structure of the sealing seat 16. The sealing seat 16 is fixedly connected to the chassis 1 and together with the sealing element 163, seals the gap between the mounting hole and the support shaft 212. The limiting cover 161 is also provided with a hole structure for the support shaft 212 to pass through.

[0110] Since the seal 163 is installed on the sealing seat 16, and the sealing seat 16 has a retaining edge on the side near the dehydration space, the installation difficulty of the seal 163 can be reduced, thereby improving the installation efficiency of the seal 163 and thus improving the production efficiency of the horizontal dehydrator. On the other hand, the sealing performance of the seal 163 can also be increased to ensure the sealing effect of the seal 163 on the gap between the mounting hole and the support shaft 212.

[0111] Furthermore, since a limiting cover 161 is provided on the side of the sealing seat 16 away from the dehydration space, and the limiting cover 161 is provided with a limiting rib 162 that abuts against the sealing member 163, the limiting cover 161 and the limiting rib 162 can be used to limit the sealing member 163, thereby further increasing the stability of the sealing member 163 and further increasing the sealing effect of the sealing member 163 on the gap between the mounting hole and the support shaft 212.

[0112] Preferably, the limiting cover 161 is fixedly connected to the sealing seat 16 by bolts, so as to facilitate the fixing of the limiting cover 161 and increase the connection stability between the limiting cover 161 and the sealing seat 16.

[0113] This application does not specifically limit the structure of the seal 163. Preferably, the seal 163 is a skeleton oil seal, and two skeleton oil seals are arranged opposite each other to further enhance the sealing effect on the gap between the sealing seat 16 and the support shaft 212. In other embodiments, the seal 163 can also be a V-ring, Y-ring, or other annular structure that can perform a sealing function.

[0114] This application does not specifically limit the structure of the connecting part 31. Preferably, the connecting part 31 is a gas pipe connector provided on the gas supply component, and the housing 1 is provided with a hole structure for the gas supply pipe connector to extend out, so as to facilitate the connection of the connecting part 31 to the pipeline. In other embodiments, the connecting part 31 can also be a pipe structure or other structures capable of transporting gas.

[0116] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0117] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
