Description

Technical Field

[0001] This utility model relates to the field of PVC stabilizer production, specifically a feeding device for PVC stabilizer production. Background Technology

[0002] PVC heat stabilizers are mainly used in PVC and other chlorine-containing polymers. They do not affect the processing and application of PVC, and can delay its thermal decomposition to a certain extent. In the current production of PVC stabilizers, feeding is required, which necessitates the use of a feeding device.

[0003] According to Chinese Patent No. CN218402777U, a feeding device for PVC stabilizer production is disclosed. This feeding device not only facilitates the storage of PVC stabilizer, but also prevents PVC stabilizer from accumulating in the storage cylinder and sticking to the inner wall of the conveyor box.

[0004] Regarding the aforementioned patent content, a material cylinder is provided for storing PVC stabilizers. However, PVC stabilizers are generally in powder form, and over time, a large amount of PVC stabilizer will adhere to the inner wall of the material cylinder. Since the material cylinder is relatively closed, with only one inlet pipe and one outlet pipe, it is inconvenient for workers to clean the inner wall of the material cylinder. As a result, the PVC stabilizer continues to adhere to the inner wall of the material cylinder, reducing the efficiency of cleaning the inner wall of the material cylinder. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a feeding device for PVC stabilizer production to solve the technical problem of inconvenience in cleaning the inner wall of the material cylinder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for PVC stabilizer production, comprising a device body, a feeding cylinder mounted on one side of the device body via a fixing frame, a stirring shaft connected inside the device body via a bearing, a cleaning assembly on the stirring shaft, and the cleaning assembly including a water guide cavity opened at the top of the stirring shaft, multiple spray pipes installed on the upper part of the outer wall of the stirring shaft, a high-pressure water pump installed at the top of the device body, a scraper ring located inside the upper part of the device body, a guide wheel installed on one side of the top of the device body, and a water outlet hole opened on one side of the bottom of the feeding cylinder, the water outlet end of the high-pressure water pump being connected to a water supply pipe, and a rotary joint being connected between the water supply pipe and the stirring shaft, a pull rope extending through to the outside of the device body being fixed on one side of the top of the scraper ring, and a downwardly inclined one-way valve being installed at the end of the spray pipe.

[0007] By adopting the above technical solution, when it is necessary to flush the inside of the main body of the device, the staff can start the high-pressure water pump to draw in external water. The water enters the water guide chamber through the water supply pipe and rotary joint, then enters the one-way valve, and is sprayed out through the one-way valve.

[0008] Furthermore, the inner wall of the water outlet is provided with threads, and the internal threads of the water outlet are connected to a threaded sealing plug. The bottom of the feeding cylinder is also provided with a sealing gasket, and the bottom of the sealing gasket is in contact with the threaded sealing plug.

[0009] By adopting the above technical solution, the threaded sealant can block the water outlet hole and prevent the PVC stabilizer raw material from being discharged through the water outlet hole.

[0010] Furthermore, one end of the pull rope passes through a guide wheel and is fitted with a limit block, which is equipped with a locking bolt.

[0011] By adopting the above technical solution, the staff can pull the pull rope through the limit block, so that the pull rope pulls the scraper ring to move upward and reset.

[0012] Furthermore, the cleaning assembly also includes a threaded hole located on the lower side of the other side of the device body, with one end of the locking bolt extending into the interior of the threaded hole.

[0013] By adopting the above technical solution, the limiting block can be locked and limited after the locking bolt is screwed into the threaded hole.

[0014] Furthermore, a feeding pipe is connected between the bottom of the main body of the device and the feeding cylinder, and a solenoid valve is installed on the feeding pipe.

[0015] By adopting the above technical solution, the PVC stabilizer raw material can enter the feeding cylinder through the discharge pipe, which facilitates feeding.

[0016] Furthermore, a mounting bracket is fixed to the top of the feeding cylinder, a motor is mounted on the mounting bracket, and the output end of the motor is connected to a conveying shaft extending into the inside of the feeding cylinder. Spiral blades are mounted on the outer wall of the conveying shaft, and a discharge pipe is connected to the upper side of one side of the feeding cylinder.

[0017] By adopting the above technical solution, when it is necessary to feed PVC stabilizer raw materials, the motor can be started. The operation of the motor can drive the conveyor shaft to rotate, which in turn drives the spiral blades to rotate.

[0018] Furthermore, sprockets are installed on the upper part of the outer wall of the conveying shaft and the upper part of the outer wall of the stirring shaft, and a chain is sleeved between the two sprockets.

[0019] By adopting the above technical solution, when the conveyor shaft rotates, it will drive the sprocket connected to it to rotate, and then drive another sprocket to rotate through the chain, which in turn drives the stirring shaft to rotate.

[0020] Furthermore, a feed hopper is installed on the top of the main body of the device, and a sealing cap is threaded to the top of the feed hopper. A stirring paddle and stirring blades are respectively installed on the outer wall of the stirring shaft.

[0021] By adopting the above technical solution, when the stirring shaft rotates, it will drive the stirring paddle and stirring blades to rotate, so as to agitate the PVC stabilizer raw materials.

[0022] Furthermore, a scraper is installed at the bottom end of the stirring shaft, and the bottom of the scraper is in contact with the lower inner wall of the main body of the device.

[0023] By adopting the above technical solution, when the stirring shaft rotates, it will drive the scraper to rotate, and the scraper can scrape off the PVC stabilizer raw material attached to the lower part of the inner wall of the device.

[0024] Furthermore, the outer wall of the scraper ring is fitted with the inner wall of the device body, and the water guiding cavity is connected to the one-way valve.

[0025] By adopting the above technical solution, the PVC stabilizer raw material adhering to the inner wall of the device body can be scraped off when the scraper ring moves down, thereby improving the cleaning efficiency of the inner wall of the device body.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model is equipped with a cleaning component. When the interior of the device body needs to be rinsed, the operator can start the high-pressure water pump to draw external water. The water enters the water guide chamber through the water supply pipe and rotary joint, then enters the one-way valve through the spray pipe, and is sprayed onto the inner wall of the device body through the one-way valve. At the same time, the motor starts, so that the stirring shaft can rotate continuously, and drive the spray pipe and one-way valve to rotate continuously for all-round spraying. As the water is continuously sprayed out, the water on the inner wall of the device will flow downward, which can continuously rinse the inner wall of the device body. The operator can also unscrew the locking bolt and release the limit block, so that the scraper ring slides downward under its own weight, so as to scrape and clean the inner wall of the device body in conjunction with the water, thereby improving the cleaning efficiency of the inner wall of the device and preventing a lot of residue from adhering to the inner wall of the device that is difficult to clean.

[0028] 2. This utility model is equipped with a locking bolt and a threaded hole. When the scraper ring is not used, the limiting block needs to be locked and limited. At this time, the operator can screw the locking bolt into the threaded hole to lock the limiting block and prevent the scraper ring from moving down to the bottom of the device and affecting the subsequent material discharge.

[0029] 3. This utility model is equipped with a water outlet, a threaded sealing plug, and a sealing gasket. After the threaded sealing plug is screwed into the water outlet, it can seal the water outlet, preventing the PVC stabilizer raw material from being discharged from the water outlet and affecting the feeding efficiency, thereby improving the sealing effect of the water outlet.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A feeding device for PVC stabilizer production, such as Figures 1-7 As shown, the device includes a main body 1. A feeding cylinder 5 is mounted on one side of the main body 1 via a fixed frame. A stirring shaft 13 is connected to the inside of the main body 1 via a bearing. A cleaning component 9 is installed on the stirring shaft 13. A discharge pipe 2 is connected between the bottom of the main body 1 and the feeding cylinder 5. A solenoid valve 3 is installed on the discharge pipe 2 so that the PVC stabilizer raw material can enter the inside of the feeding cylinder 5 through the discharge pipe 2 for convenient feeding. A mounting frame 10 is fixed on the top of the feeding cylinder 5. A motor 11 is mounted on the mounting frame 10, and the output end of the motor 11 is connected to a conveying shaft 7 extending into the inside of the feeding cylinder 5. Spiral blades 6 are installed on the outer wall of the conveying shaft 7. A discharge pipe 8 is connected to the upper side of one side of the feeding cylinder 5. When it is necessary to feed the PVC stabilizer raw material, the motor 11 can be started. The operation of the motor 11 can drive the conveying shaft 7 to rotate, which in turn drives the spiral blades 6 to rotate, so as to convey the PVC stabilizer raw material.

[0042] See Figures 2-6 Both the outer wall of the conveying shaft 7 and the outer wall of the stirring shaft 13 are equipped with sprockets 12, and a chain 15 is sleeved between the two sprockets 12. When the conveying shaft 7 rotates, it will drive the sprocket 12 connected to it to rotate, and then drive the other sprocket 12 to rotate through the chain 15, and then drive the stirring shaft 13 to rotate. The top of the main body 1 is also equipped with a feed hopper 4, and the top of the feed hopper 4 is threaded with a sealing cover. The operator can add PVC stabilizer raw materials into the main body 1 through the feed hopper 4. The outer wall of the stirring shaft 13 is equipped with a stirring paddle 14 and a stirring blade 16. When the stirring shaft 13 rotates, it will drive the stirring paddle 14 and the stirring blade 16 to rotate, so as to agitate the PVC stabilizer raw materials.

[0043] Specifically, the cleaning assembly 9 includes a water guide cavity 904 located at the top of the stirring shaft 13, multiple spray pipes 915 mounted on the upper outer wall of the stirring shaft 13, a high-pressure water pump 901 mounted on the top of the main body 1, a scraper ring 907 located inside the upper part of the main body 1, a guide wheel 906 mounted on one side of the top of the main body 1, and a water outlet 913 located on one side of the bottom of the feeding cylinder 5. The water outlet of the high-pressure water pump 901 is connected to a water supply pipe 902, and a rotary joint 903 is connected between the water supply pipe 902 and the stirring shaft 13. A pull rope 908 extending through to the outside of the main body 1 is fixed to one side of the top of the scraper ring 907. A downwardly inclined one-way valve 905 is installed at the end of the spray pipe 915. When it is necessary to clean the main body of the device... When rinsing the interior of device 1, the operator can start the high-pressure water pump 901 to draw in external water. The water enters the water guide chamber 904 through the water supply pipe 902 and the rotary joint 903, and then enters the one-way valve 905. The water is then sprayed out through the one-way valve 905. The outer wall of the scraper ring 907 is in contact with the inner wall of the device body 1. The water guide chamber 904 is connected to the one-way valve 905 so that when the scraper ring 907 moves down, it can scrape off the PVC stabilizer material attached to the inner wall of the device body 1, thereby improving the cleaning efficiency of the inner wall of the device body 1. One end of the pull rope 908 is connected to the guide wheel 906 and a limit block 909 is installed. The operator can pull the pull rope 908 through the limit block 909, so that the pull rope 908 pulls the scraper ring 907 to move up and reset.

[0044] Example 2:

[0045] Based on the above embodiment 1, in order to prevent the PVC stabilizer raw material from being discharged through the water outlet 913, the water outlet 913 needs to be sealed, so the following structure will be set.

[0046] Specifically, the inner wall of the water outlet 913 is threaded, and the internal thread of the water outlet 913 is connected to a threaded sealing plug 912. The bottom of the feeding cylinder 5 is also provided with a sealing gasket 914, and the bottom of the sealing gasket 914 fits against the threaded sealing plug 912. The threaded sealing plug 912 can block the water outlet 913 and prevent the PVC stabilizer raw material from being discharged through the water outlet 913.

[0047] Example 3:

[0048] Based on the above embodiment 1, in order to improve the stability of the scraper ring 907 and prevent the scraper ring 907 from moving downward at will, it is necessary to limit the limit block 909, so the following structure will be set.

[0049] Specifically, the limiting block 909 is provided with a locking bolt 910, and the cleaning component 9 also includes a threaded hole 911 opened on the lower side of the other side of the device body 1. One end of the locking bolt 910 extends into the interior of the threaded hole 911. When the locking bolt 910 is screwed into the interior of the threaded hole 911, the limiting block 909 can be locked and limited to prevent the scraper ring 907 from moving.

[0050] Example 4:

[0051] Based on the above embodiment 1, in order to improve the cleaning efficiency of the lower part of the inner wall of the device body 1, the following structure will be set.

[0052] See Figures 2-5 A scraper 17 is installed at the bottom of the stirring shaft 13, and the bottom of the scraper 17 is in contact with the lower inner wall of the device body 1. When the stirring shaft 13 rotates, it will drive the scraper 17 to rotate, and the scraper 17 can scrape off the PVC stabilizer raw material attached to the lower inner wall of the device body 1.

[0053] The working principle of this utility model is as follows: First, when in use, the operator can rotate the sealing cover to unscrew it from the feed hopper 4, and then add the PVC stabilizer raw material into the main body 1 of the device through the feed hopper 4. After adding, the sealing cover is screwed onto the feed hopper 4 to seal the feed hopper 4. When feeding is required, the solenoid valve 3 can be opened and the motor 11 can be started. The operation of the motor 11 can drive the conveyor shaft 7 to rotate, which in turn drives the sprocket 12 connected to it to rotate. Then, the chain 15 drives another sprocket 12 to rotate, which in turn drives the stirring shaft 13 to rotate. Then, the stirring paddle 14 and stirring blade 16 rotate, and the PVC stabilizer raw material enters the feed cylinder 5 through the discharge pipe 2. At the same time, the rotation of the conveyor shaft 7 will drive the spiral blade 6 to rotate. The spiral blade 6 will then convey the PVC stabilizer raw material upward and discharge it through the discharge pipe 8, thereby completing the feeding operation.

[0054] When the inner wall of the main body 1 needs to be cleaned, the operator can connect the inlet of the high-pressure water pump 901 to the external water supply pipe, then start the high-pressure water pump 901 and the motor 11 and open the solenoid valve 3. The high-pressure water pump 901 can draw external water, which enters the water guide chamber 904 through the water supply pipe 902 and the rotary joint 903, and then enters the one-way valve 905 through the spray pipe 915. The water is then sprayed out onto the inner wall of the main body 1 through the one-way valve 905. At the same time, the motor 11 works to make the stirring shaft 13 rotate continuously, driving the spray pipe. 915 and one-way valve 905 rotate continuously to spray water in all directions. As water is continuously sprayed out, the water on the inner wall of the device flows downward, which can continuously wash the inner wall of the device body 1. The operator can unscrew the locking bolt 910 and release the limit block 909, so that the scraper ring 907 slides downward under its own weight, so as to scrape and clean the inner wall of the device body 1 in conjunction with the water. The cleaned water and residue will enter the feeding cylinder 5 through the feed pipe 2. The inner wall of the device body 1 can be cleaned in this way.

[0055] When it is necessary to drain the water from the feed cylinder 5 and the main body 1 of the device, the operator can rotate the threaded sealing plug 912 to unscrew the threaded sealing plug 912 from the inside of the water outlet 913 so that it no longer blocks the water outlet 913, and the water will be discharged through the water outlet 913.
