Description

Technical Field

[0001] The invention relates to the technical field of aluminum powder slurry filter press, in particular to a filter press unloading auxiliary device for aluminum powder slurry production. Background Art

[0002] The filter press process in aluminum slurry production is a key solid-liquid separation step, mainly used to remove moisture and impurities in the aluminum slurry to obtain a dry aluminum powder filter cake. During filter press unloading, for filter presses with a high degree of automation, vibration devices or compressed air can be used to assist unloading, and the filter cake will fall off automatically.

[0003] However, the detached filter cake will be broken and incomplete. Since the intact filter cake is heated evenly during the drying process, the drying efficiency is higher, and the intact filter cake is easier to carry and package, reducing the difficulty of operation. Therefore, after the filtration is completed, manual labor is required to sort out the intact filter cakes, which puts a certain amount of work pressure on the staff. In addition, the broken filter cake will produce aluminum powder dust, affecting the working environment of the staff. Summary of the Invention

[0004] The purpose of the present invention is to provide a filter press unloading auxiliary device for aluminum slurry production, which can automatically sort complete filter cakes and broken filter cakes, and can automatically extract the dust generated inside the discharge box, thereby improving work efficiency and the working environment of the staff.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a filter press unloading auxiliary device for aluminum slurry production, comprising a dust removal mechanism installed on one side of the filter press, the dust removal mechanism comprising an exhaust fan located on one side of the filter press, the exhaust end of the exhaust fan being equipped with a connecting pipe, the bottom of the connecting pipe being connected to a dust suction pipe; a unloading mechanism for assisting unloading is provided on one side of the dust removal mechanism, the unloading mechanism comprising a discharge box located at the bottom of the filter press, a main shaft being rotated inside the connecting pipe, a synchronous belt being installed at one end of the main shaft, and a wire mesh located on one side of the discharge box being installed at one end of the synchronous belt. The cam is provided with a sliding plate which moves along the screw shaft when the screw shaft rotates, and a push plate which slides on the bottom of the discharge box is provided on the bottom of one side of the slide. An adjusting rod is installed in the middle part of one side of the slide, and a scraper is installed at one end of the adjusting rod; a sorting mechanism which cooperates with the slide to sort the filter cakes is installed at one end of the discharge box, and the sorting mechanism includes a sliding frame which slides on the discharge box, a telescopic spring is installed at one end of the sliding frame, 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 discharge port is provided at the bottom of one end of the discharge box.

[0006] Preferably, a storage box is installed at the air outlet end of the exhaust fan.

[0007] Preferably, an exhaust pipe is installed at the exhaust end of the exhaust fan, and the connecting pipe is connected to the exhaust pipe.

[0008] Preferably, the dust suction pipe is connected to the connecting pipe, and the dust suction pipe is located on one side of the discharge box. One side of the dust suction pipe is connected to multiple dust suction heads, and the multiple dust suction heads are connected to the discharge box through.

[0009] Preferably, the main shaft rotates on the connecting pipe, and a fan is installed at one end of the main shaft.

[0010] Preferably, one end of the screw shaft is rotatably mounted on a support leg of the filter press.

[0011] Preferably, the bearing seat on the skateboard is connected to the outer thread of the screw shaft through a ball nut pair.

[0012] Preferably, the sliding frame is provided with a scale, and the limiting rod slides on the sliding frame in a damped manner.

[0013] Preferably, a guide shaft passes through one end of the sliding frame, and the telescopic spring surrounds the outside of the guide shaft.

[0014] Preferably, both sides of the discharge box are provided with sliding grooves for the sliding rack to slide.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention utilizes a process in which the push plate pushes the filter cake to move to one end of the discharge box after the filter cake is detected. The end of the filter cake away from the push plate contacts the limiting rod after moving to a certain position. Due to the setting 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 recovery box through the discharge port, which is convenient for the staff to collect later. If the filter cake is complete, the filter cake will squeeze the limiting rod under the push of the push plate, and the limiting rod squeezes the sliding rack, and the sliding rack squeezes the telescopic spring. As a result, the staff can intuitively see the moving position of the complete filter cake through the movement of the sliding rack, which is convenient for the staff to collect the complete filter cake, thereby improving work efficiency, automatically sorting the complete filter cakes and the broken filter cakes, and automatically extracting the dust generated inside the discharge box, thereby improving work efficiency and improving the working environment of the staff.

[0017] 2. In the process of the slide moving, the scraper of the present invention will lightly scrape the top of the filter cake, thereby performing a preliminary test on the hardness of the filter cake. After the test is completed, the push plate will contact the filter cake and push the filter cake to move; thereby, the filter cake after unloading can be automatically tested, thereby improving the integrity of the filter cake.

[0018] 3. In the present invention, when the push plate pushes the filter cake, the filter cake squeezes the sliding frame, and the sliding frame squeezes the telescopic spring. Therefore, the filter cake can be tested twice by the pressure of the sliding frame and the push plate, further improving the hardness of the filter cake and facilitating the post-filter cake operation.

[0027] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The present invention provides a filter press unloading auxiliary device for aluminum slurry production, comprising a dust removal mechanism 1 installed on one side of the filter press, the dust removal mechanism 1 including an exhaust fan 11 located on one side of the filter press, a connecting pipe 15 installed at the exhaust end of the exhaust fan 11, and a dust suction pipe 14 connected to the bottom of the connecting pipe 15; a storage box 13 installed at the air outlet end of the exhaust fan 11, an exhaust pipe 12 installed at the exhaust end of the exhaust fan 11, the connecting pipe 15 connected to the exhaust pipe 12, and the dust suction pipe 14 connected to the connecting pipe 15, and the dust suction pipe 14 is located on one side of a discharge box 21, and a plurality of dust suction heads are connected to one side of the dust suction pipe 14, and the plurality of dust suction heads are connected to the discharge box 21 through-hole;

[0029] See Figures 1 to 4 As shown, during the unloading process after the filtration is completed, the filter cake falls into the inside of the discharge box 21, and the exhaust fan 11 is started at the same time. The exhaust end of the exhaust fan 11 will extract gas through the exhaust pipe 12, and connect with the connecting pipe 15 and the dust suction pipe 14 through the exhaust pipe 12. Because the dust suction pipe 14 is located on one side of the discharge box 21, and the multiple dust suction heads on the dust suction pipe 14 are connected to the discharge box 21, the exhaust end of the exhaust fan 11 will extract the dust inside the discharge box 21, and extract the extracted dust into the inside of the storage box 13 for storage, which can be reused later. Therefore, on the one hand, the dust generated by the breakage of the filter cake can be extracted to improve the working environment of the staff, and on the other hand, the dust can be collected and reused to save resources.

[0030] A discharge mechanism 2 for assisting discharge is provided on one side of the dust removal mechanism 1. The discharge mechanism 2 includes a discharge box 21 located at the bottom of the filter press. A main shaft 22 rotates inside the connecting pipe 15. A synchronous belt 23 is installed at one end of the main shaft 22. A screw shaft 24 located on one side of the discharge box 21 is installed at one end of the synchronous belt 23. A slide 25 slides on the screw shaft 24 and moves along the screw shaft 24 when the screw shaft 24 rotates. A push plate 27 that slides on the bottom of the discharge box 21 is provided at the bottom of one side of the slide 25. An adjusting rod 26 is installed in the middle part of one side of the slide 25, and a scraper 28 is installed at one end of the adjusting rod 26. 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 screw shaft 24 is rotatably installed on the support leg of the filter press. The bearing seat on the slide 25 is connected to the outer thread of the screw shaft 24 through a ball nut pair.

[0031] See Figures 2 to 7As shown, during the operation of the exhaust fan 11, the exhaust pipe 12 is connected to the connecting pipe 15 to extract gas, and the gas will cause the fan on the main shaft 22 to rotate, thereby 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 screw shaft 24 to rotate. Because the bearing seat on the slide plate 25 is connected to the outer thread of the screw shaft 24 through a ball nut pair, during the rotation of the screw shaft 24, the slide plate 25 moves along the screw shaft 24, and the slide plate 25 drives the push plate 27 to move, and the push plate 27 moves along the bottom of the discharge box 21. As the slide 25 moves along the bottom of the discharge box 21, the filter cake is pushed to move. The slide 25 drives the push plate 27 to move. At the same time, the slide 25 also drives the adjustment rod 26 to move. The adjustment rod 26 drives the scraper 28 to move. Before the push plate 27 contacts the filter cake, the scraper 28 first contacts the top of the filter cake. During the movement of the slide 25, the scraper 28 lightly scrapes the top of the filter cake, thereby performing a preliminary test on the hardness of the filter cake. After the test is completed, the push plate 27 contacts the filter cake and pushes the filter cake to move. In this way, the filter cake after discharge can be automatically tested, thereby improving the integrity of the filter cake.

[0032] In addition, the position of the scraper 28 on the adjusting rod 26 can be adjusted according to the actual thickness of the filter cake to further improve the flexibility of the detection.

[0033] A sorting mechanism 3 for cooperating with the slide 25 to sort the filter cakes is installed at one end of the discharge box 21. The sorting mechanism 3 includes a sliding frame 31 that slides on the discharge box 21. A telescopic spring 35 is installed at one end of the sliding frame 31. 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. A discharge port 33 is provided at the bottom of one end of the discharge box 21. A scale is provided on the sliding frame 31, and the limiting rod 32 damps the sliding on the sliding frame 31. A guide shaft 36 passes through one end of the sliding frame 31. The telescopic spring 35 surrounds the outer side of the guide shaft 36. Both sides of the discharge box 21 are provided with sliding grooves 34 for the sliding frame 31 to slide.

[0034] See Figures 4 to 7 As shown, after the scraper 28 detects the filter cake, the push plate 27 pushes the filter cake to move to one end of the discharge box 21. After the end of the filter cake away from the push plate 27 moves to a certain position, it contacts the limiting rod 32. 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 recovery box through the discharge port 33, which is convenient for the staff to collect later.

[0035] If the filter cake is complete, the filter cake will press the limiting rod 32 under the push of the push plate 27, the limiting rod 32 will press the sliding frame 31, and the sliding frame 31 will press the telescopic spring 35. Therefore, the staff can intuitively see the moving position of the complete filter cake through the movement of the sliding frame 31, which is convenient for the staff to collect the complete filter cake and improve work efficiency.

[0036] In addition, the push plate 27 pushes the filter cake, the filter cake presses the sliding frame 31, and the sliding frame 31 presses the telescopic spring 35. Thus, the filter cake can be tested twice by the pressure of the sliding frame 31 and the push plate 27, further improving the hardness of the filter cake and facilitating the post-filter operation.

[0037] In addition, the number of limiting rods 32 and the spacing between the limiting rods 32 can be adjusted according to the size of the filter cake to improve the flexibility of the filtration. In addition, the performance of the telescopic spring 35 can be selected according to the actual situation to avoid excessive elasticity of the telescopic spring 35, which, in conjunction with the push plate 27, exerts excessive pressure on the filter cake and causes the complete filter cake to be excessively squeezed and broken.

[0038] Through the above technical solution, complete filter cakes and broken filter cakes can be automatically sorted, and the dust generated inside the discharge box 21 can be automatically extracted, thereby improving work efficiency and the working environment of the staff.

[0039] Working principle: During the unloading process after the filtration is completed, the filter cake falls into the inside of the discharge box 21, and the exhaust fan 11 is started at the same time. The exhaust end of the exhaust fan 11 will extract gas through the exhaust pipe 12, and the exhaust pipe 12 is connected with the connecting pipe 15 and the dust suction pipe 14. Because the dust suction pipe 14 is located on one side of the discharge box 21, and the multiple dust suction heads on the dust suction pipe 14 are connected with the discharge box 21, the exhaust end of the exhaust fan 11 will extract the dust inside the discharge box 21 and extract the extracted dust into the storage box 13 for storage, which can be reused later.

[0040] During the operation of the exhaust fan 11, the exhaust pipe 12 is connected to the connecting pipe 15 to extract gas, and the gas will cause the fan on the main shaft 22 to rotate, thereby driving the main shaft 22 to rotate, and the main shaft 22 drives the synchronous belt 23 to work, and the synchronous belt 23 drives the screw shaft 24 to rotate. Because the bearing seat on the slide plate 25 is connected to the outer thread of the screw shaft 24 through a ball nut pair, during the rotation of the screw shaft 24, the slide plate 25 moves along the screw shaft 24, and the slide plate 25 drives the push plate 27 to move, and the push plate 27 moves along the bottom of the discharge box 21. 7 pushes the filter cake to move in the process of moving along the bottom of the discharge box 21. The slide plate 25 drives the push plate 27 to move. At the same time, the slide plate 25 also drives the adjustment rod 26 to move. The adjustment 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 lightly scrape the top of the filter cake, thereby preliminarily testing the hardness of the filter cake. After the test is completed, the push plate 27 will contact the filter cake and push the filter cake to move. In this way, the filter cake after discharge can be automatically tested, thereby improving the integrity of the filter cake.

[0041] After the scraper 28 detects the filter cake, the push plate 27 pushes the filter cake to move to one end of the discharge box 21. In the process, 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 discharge port 33, which is convenient for the staff to collect later; if the filter cake is complete, the filter cake will squeeze the limiting rod 32 under the push of the push plate 27, the limiting rod 32 squeezes the sliding frame 31, and the sliding frame 31 squeezes the telescopic spring 35. Therefore, the staff can intuitively see the moving position of the complete filter cake through the movement of the sliding frame 31, which is convenient for the staff to collect the complete filter cake and improve work efficiency.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
