Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal equipment, and in particular to a kitchen waste coarse residue squeezing and transferring device and a hydraulic system. Background Art

[0002] With the acceleration of urbanization, the problem of food waste disposal has become increasingly prominent, becoming a major factor affecting urban environmental sanitation and sustainable development. To effectively address this challenge, food waste dehydration and pretreatment processes have emerged. The current mainstream model uses screw extruders for dehydration, followed by spiral conveying, and then collection and transportation via transfer boxes. However, this model is not perfect in practice and still has some issues that cannot be ignored.

[0003] Currently, screw extruders suffer from low dehydration rates due to factors such as raw material properties, screw shaft speed, equipment structure, and operating conditions. This results in high moisture and oil contents in the discharged slag. This can increase equipment load and reduce efficiency during subsequent processing. It can also cause liquid to leach out during waste transportation and processing, exacerbating environmental pollution. Furthermore, there are a number of issues, including significant oil and water losses, leakage and odor during transfer, and substandard incineration fill levels.

[0004] The particle size of the incoming material during the screw extruder operation usually needs to be controlled between 40-60mm to ensure the smooth progress of the extrusion process. However, in actual operation, due to the complex composition of food waste, it often contains impurities of various sizes. This requires careful screening and crushing work in the dehydration pretreatment stage, which increases the complexity and cost of the treatment process. In addition, the screw extruder is extremely sensitive to hard foreign matter in the material. Once the material contains hard foreign matter such as steel plates, it will not only cause serious wear on the blades, but may also cause equipment failure, affecting the normal operation of the entire treatment process. Therefore, strict screening and magnetic separation measures must be taken before extrusion to ensure that the material does not contain hard foreign matter. However, these additional processing steps will further increase processing costs and time.

[0005] After extrusion, the impurities are transported via a screw conveyor to a transfer box, which then delivers the material to the final processing station. This process requires the coordinated operation of multiple devices, resulting in numerous steps and reduced processing efficiency. Furthermore, each device requires separate maintenance and upkeep, which increases the cost and difficulty of equipment maintenance. Summary of the Invention

[0006] The purpose of the present invention is to provide a food waste coarse residue squeezing and transferring device, which has a simple structure, low construction and operation costs, and is easy to maintain. It can fully squeeze the food waste through two-stage compression, greatly reducing the water content and oil content of the food waste after squeezing, and has good applicability and strong practicality.

[0007] The technical solution adopted to achieve the purpose of the present invention is:

[0008] A device for squeezing and transferring coarse residue from kitchen waste comprises a box body, the inner cavity of which comprises a storage bin and a feed compression bin; the upper portions of the storage bin and the feed compression bin are separated by a baffle, and the lower portions are connected to form a storage inlet; a compression assembly and a feed assembly arranged above the compression assembly are provided in the feed compression bin, and the area below the feed assembly in the feed compression bin is a primary compression chamber, and a liftable gate is provided in the feed compression bin close to the baffle.

[0009] Furthermore, the liftable gate is fixedly connected to the top of the feed compression bin through the gate cylinder, and the liftable gate opens or closes the storage entrance by rising or falling; when the liftable gate is closed, the compression component performs primary compression on the coarse food waste residue in the primary compression chamber, and when the liftable gate is opened, the compression component pushes the coarse food waste residue after the primary compression into the storage bin for secondary compression.

[0010] Furthermore, in the storage bin and the feed compression bin, water filtering baffles are provided near the bottom plate and the side plates of the cavity, and support columns are provided between the water filtering baffles and the bottom plate and the side plates.

[0011] Furthermore, the bottom plate of the storage bin is higher in the middle and lower on both sides, and the cross section is an "eight" shaped structure.

[0012] Furthermore, the compression assembly includes a cylinder base, a compression cylinder and a movable push head. The cylinder base is fixed to the inner wall of the feed compression bin; one end of the compression cylinder is fixed to the cylinder base, and the other end is fixedly connected to the movable push head; the compression cylinder can push the movable push head to move along the direction of the storage bin.

[0013] Furthermore, the feed assembly includes a first feed baffle and a second feed baffle that are arranged at an angle; the first feed baffle is arranged on a side close to the storage bin, and the second feed baffle is arranged on a side close to the cylinder base, and the area between the first feed baffle and the second feed baffle forms a feed port, which is funnel-shaped.

[0014] Furthermore, a feed cover is movably connected between the feed assembly and the compression assembly, and the feed cover is closed when the compression assembly is working.

[0015] Another object of the present invention is to propose a hydraulic system for food waste coarse residue squeezing and transferring equipment, in which the hydraulic pump station in the system is independently arranged outside the box body, saving the loading space of the box body; and a set of hydraulic pump stations can correspond to multiple boxes, greatly reducing the procurement and maintenance costs.

[0016] The technical solution adopted to achieve another purpose of the present invention is: a hydraulic system for a food waste coarse residue squeezing and transferring device, including the above-mentioned food waste coarse residue squeezing and transferring device, and also including a hydraulic pump station and a high-pressure hose. The hydraulic pump station is arranged outside the box, and the hydraulic pump station and the oil cylinder on the food waste coarse residue squeezing and transferring device are detachably connected by a high-pressure hose.

[0017] Furthermore, it also includes a hydraulic valve group arranged between the hydraulic pump station and the high-pressure hose.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention separates the compression component from the storage bin, achieving two-stage squeezing and dehydration of food waste. This method has an excellent dehydration effect on coarse food waste with high moisture content, solving the current problems of high moisture content in coarse food waste pre-treated, large oil and water losses, leakage and odor during transportation, and substandard incineration filling index. Furthermore, the water and oil in the squeezing process can be recycled, avoiding resource waste.

[0020] 2. The device of the present invention has a simple structure, low construction and operation costs, and is easy to maintain. At the same time, it can realize the integration of dehydration and transportation of materials, and can also adapt to materials of various particle sizes and compositions, without the need for additional detailed screening and crushing work, thus simplifying the processing flow and greatly reducing the processing cost and time.

[0021] 3. The water filter baffle of the present invention can ensure that the water filtered out of the kitchen waste when it is compressed and static can be discharged promptly and quickly, thereby improving the overall water filtering effect;

[0022] 4. The bottom plate of the storage bin in the present invention is high in the middle and low on both sides, and the cross-section is an "eight"-shaped structure, which can form a certain slope at the bottom of the box, thereby ensuring that water that penetrates into the bottom of the box gathers on both sides of the box and is discharged from the drainage valves on both sides of the box to avoid accumulation inside the box;

[0023] 5. The hydraulic pump station in the hydraulic system of the present invention is independently arranged outside the box, saving the loading space of the box; and one set of hydraulic pump stations can correspond to multiple boxes, greatly reducing the purchase and maintenance costs.

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the following will be a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1 to 7As shown, a food waste coarse residue squeezing and transferring device includes a box body 1, the inner cavity of the box body 1 includes a storage bin 2 and a feed compression bin 3; the upper parts of the storage bin 2 and the feed compression bin 3 are separated by a baffle 4, and the lower parts are connected to form a storage inlet 5; a compression component 6 and a feed component 7 arranged above the compression component 6 are provided in the feed compression bin 3, and the area below the feed component 7 in the feed compression bin 3 is a first-level compression chamber 19 (specifically, as shown in FIG. Figure 3 As shown), a liftable gate 8 is provided in the feed compression bin 3 close to the baffle 4.

[0039] The device of the present invention is primarily used for squeezing coarse food waste at food waste treatment stations. The housing 1 is divided into two parts by a baffle 4: a storage bin 2 and a feed compression bin 3. The feed compression bin 3 is used to independently house the feed assembly 7 and the compression assembly 6; the primary compression chamber 19 is primarily used for primary compression of the coarse food waste; the storage bin 2 is primarily used for secondary compression of the coarse food waste for storage. The edge of the baffle 4 is fixedly connected to the interior of the housing 1, either by welding or bolting. The bottom of the baffle 4 is suspended in the air, not in contact with the interior, to form openings in the storage bin 2 and the feed compression bin 3, serving as a storage inlet 5.

[0040] During operation, the food waste falls through the feed assembly 7 into the primary compression chamber 19, where it undergoes primary compression. The liftable gate 8 closes at this point. The compression assembly 6 then pushes the waste toward the storage bin 2, where it passes through the storage inlet 5 below the baffle 4 and enters the storage bin 2 for secondary compression. After the secondary compression, the coarse food waste residue is stored in the storage bin 2.

[0041] The present invention separates the storage bin 2 from the feed compression bin 3 by a baffle 4, and sets the bottom of the feed compression bin 3 as a first-level compression chamber 19, which can realize two-stage squeezing and dehydration of garbage, and has an excellent dehydration effect on coarse food waste with high moisture content. It solves the current problems of high moisture content of coarse food waste after pretreatment, large oil and water loss, leakage and odor during transportation, and substandard incineration filling index.

[0042] like Figure 3 and Figure 4 As shown, in the present invention, the liftable gate 8 is fixedly connected to the top of the feed compression bin 3 via a gate cylinder 9, and the liftable gate 8 opens or closes the storage inlet 5 by rising or falling. To ensure the stability of the operation of the liftable gate 8, the present invention preferably has more than two gate cylinders 9, and the present invention preferably has two gate cylinders 9.

[0043] like Figure 3 and Figure 5As shown, in the present invention, water filter baffles 11 are installed near the bottom and side panels of the storage bin 2 and the feed compression bin 3, and support columns 12 are provided between the water filter baffles 11 and the bottom and side panels. The water filter baffles 11 of the present invention are primarily used to filter out water that permeates the food waste. The support columns 12 are provided to secure the water filter baffles 11 and to separate the water filter baffles 11 from the inner wall of the housing 1, ensuring a certain gap between the water filter baffles 11 and the inner wall of the housing 1, ensuring that the water squeezed from the food waste can flow out smoothly. The water filter baffles 11 are wear-resistant and corrosion-resistant water filter layers. When the food waste is compressed and stationary, the water filtered out can be quickly and quickly drained. The wear-resistant and wear-resistant filter mesh layer enhances the overall water filtration effect. In the actual design, drain valves are placed on both sides of the housing 1. Water that permeates the water filter baffles 11 into the inner cavity of the housing 1 is discharged through the drain valves, preventing secondary contamination caused by dripping during transportation. In addition, the upper edges of the water filter baffles 11 are seamlessly connected to the inner cavity of the box body 1 to prevent garbage from falling into the gap between the water filter baffles 11 and the inner cavity of the box body 1. In actual use, the number of layers of the water filter baffles 11 can be designed to be two layers.

[0044] like Figure 4 As shown, in the present invention, the bottom plate of the storage bin 2 is higher in the middle and lower on both sides, and its cross-section is an "eight"-shaped structure. This structure can form a certain slope at the bottom of the box body 1, thereby ensuring that water that penetrates the bottom of the box body 1 flows to the sides of the box body 1 and is then discharged through the drainage valves on both sides of the box body 1, avoiding accumulation inside the box body 1.

[0045] like Figure 3 As shown, in the present invention, the compression assembly 6 includes a cylinder base 601, a compression cylinder 602, and a movable pusher head 603. The cylinder base 601 is fixed to the inner wall of the feed compression bin 3. One end of the compression cylinder 602 is fixed to the cylinder base 601, and the other end is fixedly connected to the movable pusher head 603. The compression cylinder 602 can push the movable pusher head 603 to move along the direction of the storage bin 2. During the second stage of compression, the movable pusher head 603 will extend into the storage bin 2.

[0046] There are two compression cylinders 602 , and the two compression cylinders 602 are arranged crosswise. When compression is performed, the two compression cylinders 602 cooperate to achieve extension, thereby driving the moving push head 603 to move.

[0047] In the present invention, the feed assembly 7 includes a first feed baffle 701 and a second feed baffle 702 that are arranged at an angle; the first feed baffle 701 is arranged on a side close to the storage bin 2, and the second feed baffle 702 is arranged on a side close to the cylinder base 601, and the area between the first feed baffle 701 and the second feed baffle 702 forms a feed port, which is funnel-shaped.

[0048] The tops of the first feed baffle 701 and the second feed baffle 702 are fixedly connected to the feed compression chamber 3. A gate baffle 15 assembly is provided below the first baffle, which is perpendicular to the liftable gate 8. The gate baffle 15 can act as a barrier when the movable pusher 603 compresses the garbage in the compression chamber, preventing the garbage from overflowing the primary compression chamber 19.

[0049] like Figure 3 As shown, a feed cover plate 10 is movably connected between the feed assembly 7 and the compression assembly 6 , and the feed cover plate 10 is closed when the compression assembly 6 is working.

[0050] A working process of the liftable gate 8 of the present invention is as follows:

[0051] During operation, the liftable gate 8 closes first, allowing the food waste to fall into the compression assembly 6 through the feed assembly 7. The compression assembly 6 pushes the waste toward the storage bin 2. Simultaneously, the feed cover 10 closes under the influence of the compression assembly 6, preventing the waste from the feed assembly 7 from entering the compression assembly 6. At this point, the area between the liftable gate 8, the feed cover 10, and the compression assembly 6 where the food waste is stored forms the primary compression chamber 19. Since the liftable gate 8 is closed, the compression assembly 6 pushes the food waste in the compression chamber toward the liftable gate 8, squeezing the food waste, a process known as primary compression. After a certain period of compression, the liftable gate 8 opens, and the compression assembly 6 pushes the food waste after primary compression into the storage bin 2. The compression assembly 6 and feed cover 10 then return to their original positions, allowing the next feeding cycle to continue. Once a certain amount of food waste has been loaded into the storage bin 2, the compression assembly 6 directly performs secondary compression on the food waste in the storage bin 2, with the liftable gate 8 remaining open during the secondary compression.

[0052] like Figures 1 to 3 、 Figure 5 、 Figure 6 As shown, in the present invention, a discharge door 13 is provided at the end of the storage bin 2 away from the feed compression bin 3. Discharge door 13 is similar to the discharge door 13 commonly found in mobile compression bins in the prior art and is primarily used for unloading or maintenance. Discharge door 13 is equipped with a discharge cylinder assembly 16, which switches the discharge door 13 between open and closed. Furthermore, discharge door 13 is equipped with a manual safety lock 17, which serves as a safeguard to prevent the discharge door 13 from accidentally opening due to excessive garbage loading.

[0053] like Figure 1 、 Figure 3 and Figure 5As shown, in the present invention, a top cover door 14 is also provided on the top of the storage bin 2. When the device is compressing food waste within the station, the top cover door 14 is open. During design, a cover cylinder 18 can be configured on the top cover door 14, which can be opened automatically or manually. After packing is completed, the top cover door 14 is closed, and the entire device is transported to the unloading site via a hook truck, ensuring a fully enclosed transport process and preventing odor leakage and secondary pollution.

[0054] The device of the present invention has a simple structure, low operating costs, and is easy to maintain. It can also achieve integrated dehydration and transfer of materials, and can accommodate materials of various particle sizes and compositions, eliminating the need for additional detailed screening and crushing, simplifying the processing flow and significantly reducing processing costs and time.

[0055] Example 2

[0056] This embodiment is a hydraulic system for a food waste coarse residue pressing and transferring device, which is applied to the food waste coarse residue pressing and transferring device of embodiment 1. Based on the device of embodiment 1, this embodiment also includes a hydraulic pump station and a high-pressure hose. The hydraulic pump station is arranged outside the box 1, and the hydraulic pump station and the oil cylinders on the food waste coarse residue pressing and transferring device (mainly including the gate oil cylinder 9, the cover oil cylinder 18, the compression oil cylinder 602 and the oil cylinder on the discharge oil cylinder assembly 16) are detachably connected through the high-pressure hose. Figure 8 It also includes a hydraulic valve group arranged between the hydraulic pump station and the high-pressure hose.

[0057] The hydraulic system of this embodiment is primarily installed in a food waste disposal station, with the hydraulic pump station independently located outside the housing 1. When the cylinders within the housing require oil, high-pressure hoses are connected to the cylinders within the housing. In practical design, housing 1 should be equipped with quick-connect ports for connecting to the high-pressure hoses to facilitate the transfer of hydraulic oil from the hydraulic pump station to the corresponding cylinders.

[0058] A hydraulic pump station primarily consists of an oil tank, a hydraulic pump, and an oil filter. The hydraulic pump draws hydraulic oil from the tank and, through pressure, delivers it to components like the cylinder and hydraulic valve block. Common hydraulic pumps are available, such as gear pumps, vane pumps, and plunger pumps, depending on your needs.

[0059] The hydraulic valve group is the control element of the hydraulic system in this invention. It primarily consists of a multi-way reversing valve, a pressure valve, and a flow valve. It controls the direction and flow of hydraulic oil to control the speed and height of the cylinder. High-pressure hoses connect the hydraulic pump station, cylinder, and hydraulic valve group to ensure smooth flow of hydraulic oil throughout the system.

[0060] Example 3

[0061] A control system for a food waste coarse residue squeezing and transferring device, comprising the food waste coarse residue squeezing and transferring device and a hydraulic system, further comprising a first displacement sensor, a second displacement sensor, a first pressure sensor, a second pressure sensor, a control device, and an alarm module; the first displacement sensor, the second displacement sensor, the first pressure sensor, the second pressure sensor, the alarm module, and the oil cylinder on the food waste coarse residue squeezing and transferring device are all connected to the control device, specifically as follows Figure 8 shown.

[0062] In this embodiment, a first displacement sensor is provided on the movable pusher head 603, and a second displacement sensor is provided on the liftable gate 8. A first pressure sensor is provided in the oil circuit of the compression cylinder 602, and a second pressure sensor is provided in the oil circuit of the gate cylinder 9, which is provided on the movable pusher head 603. The control device can be a commonly used touch-operable terminal, and the alarm module can be a warning light or voice prompt module electrically connected to the control device. The hydraulic system in this invention is electrically connected to the control device, and the motors of each cylinder are driven by commands from the control device.

[0063] The working requirements and modes of the present invention during actual use are as follows:

[0064] 1. Requirements for the working of compression component 6

[0065] 1. The compression cylinder 602 adopts the differential principle;

[0066] 2. When the push head 603 is in the first level of compression, it takes 15 seconds for the compression cylinder 602 to extend to the pressure holding position.

[0067] 3. The holding time during the first level compression is 20S;

[0068] 4. After the first level of compression is completed, the retraction time of the lift gate 8 is 10s;

[0069] 5. After the lifting gate is retracted, the compression cylinder 602 continues to extend, driving the moving push head 603 to fully extend. This process takes 20 seconds.

[0070] 6. After the push head is fully extended, it takes 25 seconds to retract to the starting point;

[0071] 7. Working principle of primary compression:

[0072] 1) The gate cylinder 9 of the liftable gate 8 is in the extended state. After the movable push head 603 extends 600 mm (from the initial position when the movable push head 603 is not fully extended), it stops extending and maintains pressure for 20 seconds;

[0073] 2) After the pressure maintenance is completed, the gate cylinder 9 retracts, and the compression cylinder 602 connected to the movable push head 603 continues to extend until it is fully extended and then retracts to the starting point;

[0074] 3) When the compression cylinder 602 connected to the moving push head 603 retracts to 800 mm (the initial position when the moving push head 603 is not fully extended), the gate cylinder 9 begins to extend and enters the next cycle after being fully extended.

[0075] 2. Requirements for control systems

[0076] 1. The first pressure sensor is installed in the oil circuit of the compression cylinder 602 and transmits the pressure value in the oil circuit to the control device. When the pressure detected by the pressure sensor exceeds 22MPa for 10 seconds, the equipment stops working;

[0077] 2. The control device includes an operation panel with a touch screen, which can be used to control the working state of the discharge cylinder assembly 16 to achieve the state control of the discharge door 13; at the same time, the working state of the compression cylinder 602 can be controlled by the panel operation;

[0078] 3. When the system detects that the value of the first pressure sensor on the compression cylinder 602 and the extension distance of the first displacement sensor reach the set threshold at the same time, it means that the garbage in the storage bin 2 is full. At this time, the alarm module sounds an alarm, and the alarm light flashes;

[0079] 4. The first displacement sensor provided on the compression cylinder 602 can detect the distance extended by the movable push head 603 and determine the position of the movable push head 603; the second displacement sensor provided on the gate cylinder 9 is used to detect the position of the liftable gate 8;

[0080] 5. The control device display screen can display information such as the working pressure of the movable compression cylinder 602, the position of the movable push head 603, the lifting status of the liftable gate 8, the status of the top cover door 14 and the discharge door 13, the compression holding time and the hydraulic temperature (which requires a temperature sensor to be installed in the compression chamber to achieve this).

[0081] 6. The secondary menu on the display screen of the control device can be used to set the extension distance of the mobile push head 603 and the pressure holding time.

[0082] 3. Control Logic of Control System

[0083] 1. Automatic mode

[0084] The system automatically detects the equipment's status, closing the discharge door 13, opening the top door 14, closing the lift gate 8, and retracting the movable pusher 603. Operation begins, compressing the oil cylinder 602 to push the pusher 600 mm, then stopping and maintaining pressure for 20 seconds. The lift gate 8 then lifts into position, fully extending the pusher. The pusher retracts to 800 mm, closing the lift gate 8, and returning it to its starting position. This cycle repeats until the container is full.

[0085] 2. Manual mode

[0086] The unloading door 13, the top cover door 14, the liftable gate 8 and the movable push head 603 can be controlled in real time through the buttons or touch screen of the control device.

[0087] 3. Emergency Mode

[0088] When the automatic mode fails, the lift gate 8 is fully opened and the movable push head 603 can automatically cycle and compress.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be covered by the scope of the claims of the present invention.
