[0002] The pressure filtration process in the production of aluminum paste is a key solid-liquid separation step, mainly used to remove moisture and impurities in the aluminum paste to obtain a dry aluminum powder filter cake; when discharging the pressure filter, for a filter press with a relatively high degree of automation, vibration devices or compressed air can be used to assist in discharging, and the filter cake will fall off automatically; However, the fallen filter cake may be broken and incomplete. Since the complete filter cake is heated evenly during the drying process, the drying efficiency is higher, and the complete filter cake is easier to handle and package, reducing the operation difficulty. Therefore, after the pressure filtration is completed, it is necessary to manually sort out the complete filter cake, which causes a certain working pressure on the staff, and the broken filter cake will generate aluminum powder dust, affecting the working environment of the staff. Summary of the Invention

[0003] The purpose of the present invention is to provide an auxiliary device for discharging a filter press used in the production of aluminum paste, which can automatically sort out the complete filter cake and the broken filter cake, and at the same time can automatically extract the dust generated inside the blanking box, improving the work efficiency and improving the working environment of the staff.

[0004] To achieve the above purpose, the present invention provides the following technical solution: an auxiliary device for discharging a filter press used in the production of aluminum paste, including a dust removal mechanism installed on one side of the filter press. The dust removal mechanism includes an exhaust fan located on one side of the filter press. A connecting pipe is installed at the air extraction end of the exhaust fan, and a dust suction pipe is communicated with the bottom of the connecting pipe. On one side of the dust removal mechanism, there is a discharging mechanism for assisting in discharging. The discharging mechanism includes a blanking box located at the bottom of the filter press. A main shaft rotates inside the connecting pipe. One end of the main shaft is installed with a synchronous belt, and one end of the synchronous belt is installed with a lead screw shaft located on one side of the blanking box. A slide plate that moves along the lead screw shaft when the lead screw shaft rotates slides on the lead screw shaft. A push plate that slides on the bottom of the blanking box is arranged at the bottom of one side of the slide plate. An adjusting rod is installed in the middle of one side of the slide plate, and a scraping plate is installed at one end of the adjusting rod. A sorting mechanism for cooperating with the slide plate to sort the filter cake is installed at one end of the blanking box. The sorting mechanism includes a sliding frame that slides on the blanking box. One end of the sliding frame is installed with a telescopic spring, and one end of the telescopic spring is connected to the support leg of the filter press. A limiting rod slides on the sliding frame, and a blanking port is opened at the bottom of one end of the blanking box.

[0005] Preferably, a storage box is installed at the air outlet end of the exhaust fan.

[0006] Preferably, an air extraction pipe is installed at the air extraction end of the exhaust fan, and the connecting pipe is communicated with the air extraction pipe.

[0007] Preferably, the dust suction pipe is communicated with the connecting pipe, and the dust suction pipe is located on one side of the blanking box. A plurality of dust suction heads are communicated with one side of the dust suction pipe, and the plurality of dust suction heads are connected through the blanking box.

[0008] Preferably, the main shaft rotates on the connecting pipe, and a fan is installed at one end of the main shaft.

[0009] Preferably, one end of the lead screw shaft is rotatably installed on the support leg of the filter press.

[0010] Preferably, the bearing seat on the sliding plate is connected with the outer thread of the lead screw shaft through a ball screw pair.

[0011] Preferably, a scale is arranged on the sliding frame, and the limiting rod slides on the sliding frame with damping.

[0012] Preferably, a guide shaft penetrates through one end of the sliding frame, and the telescopic spring is wound around the outer side of the guide shaft.

[0013] Preferably, sliding grooves for the sliding frame to slide are formed on both sides of the blanking box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the filter cake is detected by the present invention, during the process that the push plate pushes the filter cake to move to one end of the blanking box, one end of the filter cake far from the push plate contacts the limiting rod after moving to a certain position. Due to the arrangement of the limiting rod, if the filter cake is broken, the filter cake will pass through the limiting rod under the push of the push plate and fall into the recycling box through the blanking port, which is convenient for subsequent collection by the staff. If the filter cake is complete, under the push of the push plate, the filter cake will squeeze the limiting rod, the limiting rod will squeeze the sliding frame, and the sliding frame will squeeze the telescopic spring. Thus, through the movement of the sliding frame, the staff can intuitively see the movement position of the complete filter cake, which is convenient for the staff to collect the complete filter cake, improves work efficiency, can automatically sort the complete filter cake and the broken filter cake, and at the same time can automatically extract the dust generated inside the blanking box, improving work efficiency and improving the working environment of the staff.

[0015] 2. During the movement of the sliding plate by the present invention, the scraper will gently scrape the top of the filter cake, thereby initially detecting the hardness of the filter cake. After the detection is completed, the push plate will contact the filter cake and push the filter cake to move; thus, the filter cake after unloading can be automatically detected, and the integrity of the filter cake is improved.

[0016] 3. While the push plate pushes the filter cake, the filter cake squeezes the sliding frame, and the sliding frame squeezes the telescopic spring. Thus, through the pressure of the sliding frame and the push plate, the filter cake can be detected twice, further improving the hardness of the filter cake and facilitating the subsequent operation of the filter cake.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0020] The present invention provides an auxiliary device for discharging a filter press used in the production of aluminum paste slurry, including a dust removal mechanism 1 installed on one side of the filter press. The dust removal mechanism 1 includes an exhaust fan 11 located on one side of the filter press. A connecting pipe 15 is installed at the exhaust end of the exhaust fan 11. A suction pipe 14 is communicated with the bottom of the connecting pipe 15; a storage tank 13 is installed at the air outlet end of the exhaust fan 11. An exhaust duct 12 is installed at the exhaust end of the exhaust fan 11. The connecting pipe 15 is communicated with the exhaust duct 12. The suction pipe 14 is communicated with the connecting pipe 15. And the suction pipe 14 is located on one side of the blanking box 21. A plurality of suction heads are communicated with one side of the suction pipe 14. And the plurality of suction heads penetrate and are connected with the blanking box 21; Refer to Figures 1 to 4As shown, during the process of discharging materials after the pressure filtration is completed, the filter cake falls into the interior of the blanking box 21. At the same time, the exhaust fan 11 is started. The air extraction end of the exhaust fan 11 will extract gas through the air extraction pipe 12. The air extraction pipe 12 is communicated with the connecting pipe 15 and the dust suction pipe 14. Also, because the dust suction pipe 14 is located on one side of the blanking box 21, and multiple dust suction heads on the dust suction pipe 14 are connected through the blanking box 21. Thus, the air extraction end of the exhaust fan 11 will extract the dust inside the blanking box 21 and extract the extracted dust into the interior of the storage box 13 for storage, which can be reused later. On the one hand, it can extract the dust generated by the fracture of the filter cake and improve the working environment of the staff. On the other hand, the dust can be collected and reused to save resources.

[0021] On one side of the dust removal mechanism 1, there is a blanking mechanism 2 for assisting in discharging materials. The blanking mechanism 2 includes a blanking box 21 located at the bottom of the filter press. A main shaft 22 rotates inside the connecting pipe 15. One end of the main shaft 22 is equipped with a synchronous belt 23. One end of the synchronous belt 23 is equipped with a lead screw shaft 24 located on one side of the blanking box 21. A slide plate 25 that moves along the lead screw shaft 24 when the lead screw shaft 24 rotates slides on the lead screw shaft 24. At the bottom of one side of the slide plate 25, there is a push plate 27 that slides on the bottom of the blanking box 21. In the middle part of one side of the slide plate 25, an adjusting rod 26 is installed. One end of the adjusting rod 26 is equipped with a scraper 28. The main shaft 22 rotates on the connecting pipe 15, and a fan is installed at one end of the main shaft 22. One end of the lead screw shaft 24 is rotatably installed on the support leg of the filter press. The bearing seat on the slide plate 25 is connected to the outer thread of the lead screw shaft 24 through a ball screw pair. Refer to Figures 2 to 7 As shown, during the process of the exhaust fan 11 working, when the air extraction pipe 12 is communicated with the connecting pipe 15 to extract gas, the gas will cause the fan on the main shaft 22 to rotate. Thus, the fan will drive the main shaft 22 to rotate. The main shaft 22 drives the synchronous belt 23 to work. The synchronous belt 23 drives the lead screw shaft 24 to rotate. Because the bearing seat on the slide plate 25 is connected to the outer thread of the lead screw shaft 24 through a ball screw pair, during the rotation of the lead screw shaft 24, the slide plate 25 moves along the lead screw shaft 24. The slide plate 25 drives the push plate 27 to move. The push plate 27 moves along the bottom of the blanking box 21. During the process of the push plate 27 moving along the bottom of the blanking box 21, it will push the filter cake to move. While the slide plate 25 drives the push plate 27 to move, the slide plate 25 also drives the adjusting rod 26 to move. The adjusting rod 26 drives the scraper 28 to move. Before the push plate 27 contacts the filter cake, the scraper 28 will first contact the top of the filter cake. During the movement of the slide plate 25, the scraper 28 will gently scrape the top of the filter cake. Thus, the hardness of the filter cake will be initially detected. After the detection is completed, the push plate 27 will contact the filter cake and push the filter cake to move. Thus, it can automatically detect the filter cake after discharging and improve the integrity of the filter cake. In addition, according to the actual situation of the filter cake thickness, the position of the scraper 28 on the adjusting rod 26 can be adjusted to further improve the flexibility of its detection.

[0022] One end of the blanking box 21 is provided with a sorting mechanism 3 for sorting filter cakes in cooperation with the sliding plate 25. The sorting mechanism 3 includes a sliding frame 31 sliding on the blanking box 21. One end of the sliding frame 31 is provided with a telescopic spring 35. One end of the telescopic spring 35 is connected to the support leg of the filter press. A limiting rod 32 slides on the sliding frame 31. One end of the bottom of the blanking box 21 is provided with a blanking port 33. A scale is provided on the sliding frame 31, and the limiting rod 32 slides on the sliding frame 31 with damping. One end of the sliding frame 31 is penetrated by a guide shaft 36, and the telescopic spring 35 is wound around the outside of the guide shaft 36. Both sides of the blanking box 21 are provided with chutes 34 for the sliding frame 31 to slide. Refer to Figures 4 to 7 As shown, after the scraper 28 detects the filter cake, during the process that the push plate 27 pushes the filter cake to move to one end of the blanking box 21, the end of the filter cake away from the push plate 27 contacts the limiting rod 32 after moving to a certain position. Due to the setting of the limiting rod 32, if the filter cake is broken, the filter cake will pass through the limiting rod 32 under the push of the push plate 27 and fall into the recycling box through the blanking port 33, which is convenient for the staff to collect later. If the filter cake is intact, under the push of the push plate 27, the filter cake will squeeze the limiting rod 32, the limiting rod 32 will squeeze the sliding frame 31, and the sliding frame 31 will squeeze the telescopic spring 35. Thus, the staff can intuitively see the moving position of the intact filter cake through the movement of the sliding frame 31, which is convenient for the staff to collect the intact filter cake and improves work efficiency. In addition, when the push plate 27 pushes the filter cake, the filter cake squeezes the sliding frame 31, and the sliding frame 31 squeezes the telescopic spring 35. Thus, the filter cake can be detected again through the pressure of the sliding frame 31 and the push plate 27, further improving the hardness of the filter cake and facilitating the subsequent operation of the filter cake. In addition, the number of the limiting rods 32 and the distance between the limiting rods 32 can be adjusted according to the size of the filter cake to improve the flexibility of its filtration. In addition, according to the actual situation, the performance of the telescopic spring 35 is selected to avoid the elastic performance of the telescopic spring 35 being too strong, and the pressure of the push plate 27 on the filter cake being too large, resulting in excessive extrusion and breakage of the intact filter cake. Through the above technical solutions, the intact filter cakes and the broken filter cakes can be automatically sorted, and at the same time, the dust generated inside the blanking box 21 can be automatically extracted, improving work efficiency and improving the working environment of the staff.

[0023] Working principle: During the process of discharging materials after the pressure filtration is completed, the filter cake drops into the interior of the blanking box 21. At the same time, the exhaust fan 11 is started. The air suction end of the exhaust fan 11 will extract gas through the air suction pipe 12. The air suction pipe 12 is communicated with the connecting pipe 15 and the dust suction pipe 14. Also, because the dust suction pipe 14 is located on one side of the blanking box 21, and multiple dust suction heads on the dust suction pipe 14 are connected through the blanking box 21, thus the air suction end of the exhaust fan 11 will extract the dust inside the blanking box 21 and store the extracted dust inside the storage box 13 for subsequent reuse; During the operation of the exhaust fan 11, when the air suction pipe 12 and the connecting pipe 15 are communicating to extract gas, the gas will cause the fan on the main shaft 22 to rotate. Thus, the fan will drive the main shaft 22 to rotate. The main shaft 22 drives the synchronous belt 23 to work, and the synchronous belt 23 drives the lead screw shaft 24 to rotate. Because the bearing block on the sliding plate 25 is connected to the outer thread of the lead screw shaft 24 through a ball screw pair, therefore, during the rotation of the lead screw shaft 24, the sliding plate 25 moves along the lead screw shaft 24. The sliding plate 25 drives the push plate 27 to move, and the push plate 27 moves along the bottom of the blanking box 21. During the process of the push plate 27 moving along the bottom of the blanking box 21, it will push the filter cake to move. While the sliding plate 25 drives the push plate 27 to move, the sliding plate 25 also drives the adjusting rod 26 to move, and the adjusting rod 26 drives the scraping plate 28 to move. Before the push plate 27 contacts the filter cake, the scraping plate 28 will first contact the top of the filter cake. During the movement of the sliding plate 25, the scraping plate 28 will gently scrape the top of the filter cake, thus initially detecting the hardness of the filter cake. After the detection is completed, the push plate 27 will then contact the filter cake and push the filter cake to move; Thus, the filter cake after discharging can be automatically detected, improving the integrity of the filter cake; After the scraping plate 28 detects the filter cake, during the process of the push plate 27 pushing the filter cake to move to one end of the blanking box 21, one end of the filter cake away from the push plate 27 contacts the limiting rod 32 after moving to a certain position. Due to the setting of the limiting rod 32, if it is a broken filter cake, the filter cake will pass through the limiting rod 32 under the push of the push plate 27 and fall into the recycling box through the blanking port 33, facilitating subsequent collection by the staff; If the filter cake is intact, under the push of the push plate 27, the filter cake will squeeze the limiting rod 32, the limiting rod 32 will squeeze the sliding frame 31, and the sliding frame 31 will squeeze the telescopic spring 35. Thus, through the movement of the sliding frame 31, the staff can intuitively see the movement position of the intact filter cake, facilitating the staff to collect the intact filter cake and improving work efficiency.
