Description

Technical Field

[0001] This utility model belongs to the technical field of alumina powder precipitation equipment, and specifically relates to a collection device for powder precipitation equipment. Background Technology

[0002] In the process of preparing alumina powder, it is necessary to mix the alumina solution and the materials required for the neutralization reaction and add them into the precipitation structure to obtain a mixed liquid and precipitated alumina powder. Then, the alumina powder is filtered and collected using a collection device.

[0003] In existing technologies, the collection devices often use flat-plate filters that filter and collect powders by gravity sieving. These filters do not agitate the mixture of liquid and powder falling into the filter structure. Furthermore, the powder retention capacity of the filter structure is relatively limited, as it can only filter powder through the bottom filter holes. This easily leads to a situation where a small amount of powder is retained in the filter structure, and the filter holes become heavily clogged, preventing further effective filtration of the mixture. Users need to frequently disassemble and clean the filter structure. Moreover, because the filter structure is flat, its powder storage capacity is poor, and powder is easily spilled during disassembly. Therefore, it cannot fully meet people's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a collection device for a powder sedimentation equipment. This device not only meets the basic requirements for collecting and processing powder, but also reduces the frequency of disassembly and cleaning of the filter structure and improves the stability and convenience of cleaning, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a collection device for a powder sedimentation equipment, including a collection box, a discharge pipe at the bottom of the collection box, a cover plate snapped onto the collection box, an inlet and outlet hole on the cover plate that snaps onto the cover plate, a filter screen groove that can pass through the inlet and outlet hole on the cover plate, a feed hopper corresponding to the filter screen groove at the top of the collection box, a mounting frame vertically sliding on the upper side of the collection box, a horizontal plate horizontally sliding in the mounting frame, and a stirring rake on the horizontal plate for stirring the mixture of powder and liquid in the filter screen groove.

[0006] As a further improvement of this utility model, the inner wall of the collection box is provided with connecting slide plates located on both sides of the filter screen groove, and the side end of the filter screen groove is provided with a connecting groove that is slidably connected to the connecting slide plates.

[0007] As a further improvement of this utility model, a telescopic push rod is vertically arranged on the top of the collection box, and the lower end of the output shaft of the telescopic push rod is connected to the mounting frame. A guide tube is also provided on the top of the collection box, and a guide rod that is inserted into the guide tube is provided on the top of the mounting frame.

[0008] As a further improvement of this utility model, a linear slide is provided on one side of the mounting bracket, and a mounting groove is provided on the other side of the mounting bracket. The slide seat of the linear slide is connected to one side end of the horizontal plate, and the mounting groove is slidably connected to the other side end of the horizontal plate.

[0009] As a further improvement of this utility model, the collection box is also provided with a transparent observation window corresponding to the filter screen.

[0010] As a further improvement of this invention, a support leg is also provided at the bottom of the collection box. The support leg allows the device to be suspended and supported.

[0011] As a further improvement of this utility model, a handle is provided on the cover plate. The handle allows for convenient movement of the cover plate and the filter tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the filter screen is attached to the collection box by a cover plate and corresponds to the feed hopper. The stirring rake agitates the powder and the mixture, which helps prevent clogging and promotes separation. This prevents a small amount of powder from clogging the large number of filter holes in the filter screen and affecting the subsequent filtration capacity, thereby reducing the frequency of cleaning the filter screen. Furthermore, the trough-shaped filter screen filters and retains the powder, allowing for material filtration from the bottom and side, and increasing the amount of powder retained, thus improving the overall filtration efficiency.

[0014] Secondly, the connecting groove on the inner side wall of the collection box is slidably connected to the connecting slide plate on the side of the filter screen, which facilitates disassembly and cleaning.

[0015] Third, the telescopic push rod allows the stirring rake to be inserted into or moved from the filter screen to the upper side of the filter screen, thus satisfying the need to move and stir the material in the filter screen while avoiding interference with the process of transferring the filter screen out of the collection box.

Detailed Implementation

[0023] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] like Figure 1 , 2 As shown in Figure 3, a collection device for a powder sedimentation equipment includes a collection box 101. The lower end of the collection box is conical. A discharge pipe 102 is fixedly connected to the bottom of the collection box 101. A cover plate 103 is snapped onto the collection box 101. A hand-tightening bolt 303 for screwing the collection box 101 is also provided on the cover plate 103. A threaded fastening hole for screwing the hand-tightening bolt 303 is provided on the collection box 101. An inlet / outlet hole 1 is provided on the cover for snapping onto the cover plate 103. 13. A filter screen 104 that can pass through the inlet and outlet holes 113 is fixedly connected to the cover plate 103 by a connecting rod 112. A feed hopper 105 corresponding to the filter screen 104 is fixedly connected to the top of the collection box 101. A mounting frame 106 is vertically slidably arranged on the upper side of the collection box. A horizontal plate 107 is horizontally slidably arranged in the mounting frame 106. A stirring rake 108 for stirring the mixture of powder and liquid in the filter screen 104 is provided on the horizontal plate 107.

[0025] like Figure 2 , 3 As shown, a telescopic push rod 201 is vertically arranged on the top of the collection box 101. The lower end of the output shaft of the telescopic push rod 201 is connected to the mounting frame 106. A guide tube 202 is also provided on the top of the collection box 101. A guide rod 203 that is inserted into the guide tube 202 is provided on the top of the mounting frame 106.

[0026] like Figure 2 , 3 As shown, a linear slide 204 is fixedly connected to one side of the mounting bracket 106, and a mounting groove 205 is fixedly connected to the other side of the mounting bracket 106. The slide of the linear slide 204 is connected to one side of the horizontal plate 107, and the mounting groove 205 is slidably connected to the other side of the horizontal plate 107.

[0027] Workers can feed the mixture of powder and liquid into the collection box 101 through the feed hopper 105. The mixture will fall into the filter screen 104. The powder will be trapped by the filter screen 104 because it cannot pass through the screen holes. The mixture will pass through the screen holes of the filter screen 104 and continue to fall in the collection box 101. Then it will leave the collection box 101 through the discharge pipe 102.

[0028] Simultaneously, the worker can drive the output axis of the telescopic push rod 201 to extend downwards by a certain length. With the insertion and cooperation of the guide tube 202 and the guide rod 203, the stirring rake 108 is driven to insert into the filter extension. Then, the sliding seat of the linear slide table 204 can be driven to slide. With the sliding cooperation of the mounting groove 205 and the horizontal plate 107, the horizontal plate 107 and the stirring rake 108 are moved to stir the mixed liquid in the filter screen 104, avoiding the blockage of the large number of filter holes in the filter screen 104 by a small amount of powder, which would affect the subsequent filtration capacity and reduce the cleaning frequency of the filter screen 104. Moreover, the powder is filtered and retained by the trough-shaped filter screen 104, which can filter the material from the bottom side and increase the amount of powder retained, thereby improving the overall filtration efficiency. To prevent the mixed liquid from falling directly onto the horizontal plate 107, the feeding can be paused during the stirring process.

[0029] After a period of time, once a large amount of powder has been trapped in the filter screen 104, the output axis of the telescopic push rod 201 can be shortened by a certain length, causing the stirring rake 108 to move to the upper side of the filter screen 104. Then, the addition of mixed liquid to the collection box is paused. After that, the cover plate 103 can be separated from the inlet / outlet hole 113, allowing the filter screen 104 to pass through the inlet / outlet hole 113. The cover plate 103 and the filter screen 104 can then be removed from the collection box 101 together. The powder in the filter screen 104 can be cleaned, and then the filter screen 104 can be reinstalled into the collection box 101 to continue filtering and collecting the mixed liquid.

[0030] According to another embodiment of the present invention, such as Figure 4 , 5 As shown, the inner wall of the collection box is provided with connecting slide plates 110 located on both sides of the filter screen 104, and the side end of the filter screen 104 is provided with a connecting groove 109 that is slidably connected to the connecting slide plates 110. Through the sliding engagement of the connecting slide plates 110 and the connecting grooves 109, the filter screen 104 can be moved stably relative to the collection box 101, allowing workers to easily and stably connect and separate the filter screen 104 from the collection box 101.

[0031] According to another embodiment of the present invention, such as Figure 1 , 5 As shown, the collection box 101 is also equipped with a transparent observation window 301 corresponding to the filter screen 104. Through the transparent observation window 301, the amount of powder collected in the filter screen 104 can be easily viewed, so as to promptly discharge the powder from the filter screen 104.

[0032] According to another embodiment of the present invention, such as Figure 1 As shown, a support leg 111 is also provided at the bottom of the collection box 101. The support leg 111 can provide suspension support for the device.

[0033] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a handle 302 is provided on the cover plate 103. The cover plate 103 and the filter tank can be moved easily by means of the handle 302.

[0034] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
