Description

Technical Field

[0001] This utility model belongs to the field of desiccant production technology, specifically a filtration device for desiccant production. Background Technology

[0002] Desiccants are substances that can remove some of the moisture from damp materials. Examples include calcium sulfate and calcium chloride, which dry by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, dry by physically adsorbing water.

[0003] During the production and preparation of desiccants, a filtration device is needed to screen out desiccant particles of the appropriate size. The screening method is to use a sieve. However, in the existing screening process, after screening out the required desiccant, the feeding needs to be stopped, the screened desiccant needs to be removed, and the feeding needs to be restarted for screening. Therefore, to a certain extent, this not only wastes the time and physical strength of workers, but is also inefficient. Utility Model Content

[0004] This invention provides a filtration device for desiccant production to address the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A filtration device for desiccant production includes a frame and a rectangular tube mounted on the frame. A drive motor is fixedly mounted on the frame. The rectangular tube is inclined and coaxially fixedly connected to the drive motor. An upward-opening U-shaped plate is embedded in the side of the rectangular tube along its length. The bottom surface of the U-shaped plate is a filter screen. A first guide plate is parallel to and fixedly mounted inside the rectangular tube. The discharge end of the first guide plate extends outward from the rectangular tube. A second guide plate is parallel to and mounted above the first guide plate. The feed end of the second guide plate is opposite to the discharge end of the upward-opening U-shaped plate. A vibration motor is mounted on the rectangular tube.

[0007] In use, one side of the rectangular tube faces upwards, so the opening of the U-shaped plate on that side faces upwards. Unfiltered desiccant is then placed inside the U-shaped plate. Under the action of gravity and the vibration of the vibrating motor, the desiccant moves downwards while being screened, thus screening out the desired desiccant, which falls onto the second guide plate, while unsuitable desiccant falls onto the first guide plate. This achieves desiccant screening, eliminating the need for workers to remove the screened desiccant and refill it for screening, saving workers' time and effort, and improving efficiency. Furthermore, when the filter screen becomes clogged after a period of use, rotating the rectangular tube allows the unused U-shaped plate opening to face upwards for continued screening, and the clogged filter screen is cleaned, thus saving the time spent on stopping the machine to clean the filter screen, further improving efficiency.

[0008] Preferably, the U-shaped plate includes a filter screen and side plates disposed on both sides of the filter screen, wherein the filter screen and the side plates are detachably and fixedly connected. The detachable filter screen allows for easy removal for further cleaning.

[0009] Preferably, the two side plates have grooves on their opposite surfaces, allowing the filter screen to slide within the grooves. The bottom surface of the side plates has screw holes, and the filter screen has through holes corresponding to these screw holes. Bolts are threaded into the screw holes, and when the filter screen is in the grooves, the bolts pass through the through holes. The bolts secure the filter screen to the side plates, while the grooves facilitate the removal of the filter screen.

[0010] Preferably, an air inlet pipe is provided inside the rectangular tube. One end of the air inlet pipe is closed, and the other end extends out of the rectangular tube and connects to the air pump. Several downward-facing nozzles are connected along the length of the air inlet pipe. Gas enters the tube through the air pump and is ejected from the air inlet pipe and nozzles, thereby achieving backflushing cleaning of the filter screen inside the downward-facing U-shaped plate.

[0011] Preferably, the system also includes a feeding hopper, which is supported by a bracket and has its outlet located directly above the U-shaped plate with the U-shaped opening facing upwards. The feeding hopper is controlled by a valve, which enables the feeding hopper to convey materials onto the U-shaped plate.

[0012] Preferably, both the first and second guide plates are equipped with corresponding receiving trays at their discharge ends. The receiving trays are used to receive materials.

[0013] The beneficial effects of this utility model are as follows: The use of this application eliminates the need for workers to take out the sieved desiccant and put it back in for screening, saving workers' time and energy, while improving efficiency. At the same time, when the filter screen becomes clogged after a period of use, rotating the rectangular tube allows the unused U-shaped plate to face upwards for continued screening and cleaning of the clogged filter screen, thus saving the time spent on stopping the machine to clean the filter screen and further improving efficiency.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] A filtration device for desiccant production, such as Figures 1-3 As shown, it includes a frame 1 and a rectangular tube 2 mounted on the frame 1. A drive motor 3 is fixedly mounted on the frame 1. The rectangular tube 2 is inclined and coaxially fixedly connected to the drive motor 3. An upward-opening U-shaped plate 4 is embedded in the side of the rectangular tube 2 along its length. The bottom surface of the U-shaped plate 4 is a filter screen 42. A first guide plate 5 is parallel and fixedly mounted inside the rectangular tube 2. The feeding end of the first guide plate 5 extends outward from the rectangular tube 2. A second guide plate 6 is parallel and mounted above the first guide plate 5. The bottom surface of the second guide plate 6 is fixedly connected to a fixed support rod. The feeding end of the second guide plate 6 is opposite to the feeding end of the upward-opening U-shaped plate 4. A vibration motor is mounted on the rectangular tube 2.

[0022] It also includes a feeding hopper 9, which is supported by a bracket and has its outlet located directly above the U-shaped plate 4 with the U-shaped opening facing upwards. The feeding hopper 9 is controlled by a valve, which enables the feeding hopper 9 to convey materials onto the U-shaped plate 4.

[0023] In use, one side of the rectangular tube 2 faces upwards, so the opening of the U-shaped plate 4 on that side faces upwards. Then, the unfiltered desiccant is placed in the U-shaped plate 4. Under the action of gravity and the vibration of the vibrating motor, the desiccant moves downwards and is screened, so that the desired desiccant falls onto the second guide plate 6, while the unsuitable desiccant falls onto the first guide plate 5, thus realizing the screening of the desiccant. This saves workers from having to take out the screened desiccant and put it back in for screening again, saving workers' time and energy, and improving efficiency. At the same time, when the filter screen 42 becomes clogged after a period of use, the rectangular tube 2 is rotated so that the opening of the unused U-shaped plate 4 faces upwards to continue screening, and the clogged filter screen 42 is cleaned, thus saving the time spent on stopping the machine to clean the filter screen 42, further improving efficiency.

[0024] The U-shaped plate 4 includes a filter screen 42 and side plates 41 disposed on both sides of the filter screen 42. The filter screen 42 and the side plates 41 are detachably and fixedly connected. The detachable filter screen 42 allows for easy removal for further cleaning.

[0025] The two side plates 41 have grooves 7 on their opposite surfaces. The filter screen 42 slides within the grooves 7 on both sides. The bottom surface of the side plates 41 has screw holes, and the filter screen 42 has through holes corresponding to the screw holes. Bolts are threaded into the screw holes. When the filter screen 42 is located within the grooves 7, the bolts pass through the through holes. The bolts secure the filter screen 42 to the side plates 41, while the grooves 7 facilitate the removal of the filter screen 42.

[0026] An air inlet pipe 8 is provided inside the rectangular tube 2. One end of the air inlet pipe 8 is closed, and the other end extends out of the rectangular tube 2 and is connected to the air pump. Several downward-facing nozzles are connected to the air inlet pipe 8 along its length. Gas enters the tube through the air pump and is ejected from the air inlet pipe 8 and the nozzles, thereby achieving backflushing cleaning of the filter screen 42 inside the downward-facing U-shaped plate 4.

[0027] The discharge ends of both the first guide plate 5 and the second guide plate 6 are equipped with corresponding receiving trays 10. The receiving trays 10 can receive materials.

[0028] The use of this application eliminates the need for workers to remove the sieved desiccant and refill it for screening, saving workers' time and effort, while improving efficiency. Furthermore, when the filter screen 42 becomes clogged after a period of use, rotating the rectangular tube 2 allows the unused U-shaped plate 4 to face upwards for continued screening, and cleans the clogged filter screen 42, thus saving the time spent cleaning the filter screen 42 by stopping the machine, further improving efficiency.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
