Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a magnetic separation filtration composite adsorbent recovery box for belt filters. Background Technology

[0002] Adsorbent washing is a process that uses specific adsorbent materials to selectively adsorb impurities or target components from a brine solution. It is mainly used in salt refining, decolorization and impurity removal, and resource recovery.

[0003] When using a belt filter to recover adsorbent, a recovery device is installed at the outlet of the salt washing section of the belt filter. When using the recovery device to recover adsorbent, the adsorbent in the liquid is generally recovered by filtering through a filter screen. Single filtration results in poor adsorbent recovery effect, resulting in a large amount of adsorbent in the filtered liquid, which leads to waste of adsorbent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where single-pass filtration results in poor adsorbent recovery, leading to a high adsorbent content in the filtered liquid and waste of adsorbent. The proposed invention is a magnetic separation filtration composite adsorbent recovery box for belt filters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a magnetic separation filtration composite adsorbent recovery box for a filter press, including a recovery box body. A partition is connected inside the recovery box body, dividing it into a magnetic separation chamber and a filtration chamber. A motor is fixedly connected to the recovery box body, and the output end of the motor extends into the magnetic separation chamber and is fixedly connected to a permanent magnet drum. An inlet pipe for guiding material is connected to the upper end of the recovery box body. A scraping mechanism for scraping material from the surface of the permanent magnet drum is connected to the upper end of the partition. A discharge pipe is connected to the partition. An automatic backwashing disc filter is connected inside the filtration chamber, and the inlet end of the automatic backwashing disc filter is connected to the partition.

[0006] Preferably, the scraping mechanism includes a groove seat, the groove seat is fixedly connected to the upper end of the partition, a scraper is slidably connected to the upper end of the groove seat, a spring is fixedly connected to the bottom end of the scraper, one end of the spring is fixedly connected to the groove seat, and the upper end of the scraper is in contact with the bottom end of the permanent magnet roller.

[0007] Preferably, the springs are provided in a plurality of them and are evenly distributed along the length direction of the scraper.

[0008] Preferably, the upper interior of the recycling bin is connected to a dispersing mechanism for dispersing liquid. The dispersing mechanism includes a guide frame, which is fixedly connected to the upper interior of the recycling bin. The guide frame is inclined downward toward the permanent magnet drum.

The baffle is inclined downward toward the permanent magnet drum. A gap is provided between the baffle and the guide frame, and the gap is located above the permanent magnet drum.

[0009] Preferably, each of the buffer plates is inclined upwards.

[0010] Preferably, a filtration mechanism is connected inside the filtration chamber.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1: Refer to Figure 1-4 A magnetic separation filter composite adsorbent recovery box for a filter press includes a recovery box body 1. A partition 2 is connected inside the recovery box body 1, dividing the recovery box body 1 into a magnetic separation chamber 3 and a filtration chamber 4. A motor 6 is fixedly connected to the recovery box body 1. The output end of the motor 6 extends into the magnetic separation chamber 3 and is fixedly connected to a permanent magnet roller 7. An inlet pipe 5 for guiding material is connected to the upper end of the recovery box body 1. A scraping mechanism 8 for scraping material from the surface of the permanent magnet roller 7 is connected to the upper end of the partition 2. A discharge pipe 9 is connected to the partition 2. An automatic backwashing disc filter 10 is connected inside the filtration chamber 4. The inlet end of the automatic backwashing disc filter 10 is connected to the partition 2.

[0018] Working principle: After the motor 6 is powered on and started, it drives the permanent magnet drum 7 to rotate. The liquid with adsorbent is introduced into the magnetic separation chamber 3 through the liquid inlet pipe 5. After the introduced liquid comes into contact with the rotating permanent magnet drum 7, the permanent magnet drum 7 uses magnetic force to adsorb the adsorbent in the liquid and make it adhere to the drum surface. During the rotation of the permanent magnet drum 7, the scraping mechanism 8 slides relative to the drum surface and scrapes off the adsorbed magnetic adsorbent. The scraping mechanism 8 can effectively remove the adsorbent on the surface of the permanent magnet drum 7, avoid the magnetic drum from being blocked, and thus extend the service life of the equipment. The scraped-off adsorbent enters the filter chamber 4 through the discharge pipe 9. The liquid after being adsorbed by the permanent magnet drum 7 is introduced into the automatic backwash disc filter 10. The filter further filters the liquid, achieving efficient separation of the adsorbent and the washing brine. The magnetic force generated by the rotation of the permanent magnet drum 7 can efficiently adsorb the magnetic adsorbent in the liquid. The liquid after magnetic separation enters the automatic backwash disc filter 10 for deep filtration to ensure the cleanliness of the liquid. This achieves rapid separation of the adsorbent and the liquid, improving the separation efficiency. After two filtrations, the residual amount of adsorbent in the liquid is significantly reduced, avoiding waste of adsorbent.

[0019] Example 2: When the scraping mechanism 8 scrapes off the magnetic adsorbent from the surface of the permanent magnet roller 7, the scraping of the surface of the permanent magnet roller 7 is not thorough. (Refer to...) Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the scraping mechanism 8 includes a groove seat 81, the groove seat 81 is fixedly connected to the upper end of the partition plate 2, the upper end of the groove seat 81 is slidably connected to a scraper 82, the bottom end of the scraper 82 is fixedly connected to a spring 83, one end of the spring 83 is fixedly connected to the groove seat 81, and several springs 83 are provided and are evenly distributed along the length direction of the scraper 82. The upper end of the scraper 82 is in contact with the bottom end of the permanent magnet roller 7. The permanent magnet roller 7 presses the scraper 82, causing it to compress the spring 83 downwards. The spring 83, after being compressed, generates an upward elastic force, pushing the scraper 82 back to its original position, keeping the scraper 82 in close contact with the bottom of the permanent magnet roller 7, thereby improving the scraping effect on the roller surface.

[0020] Example 3: When the liquid is guided to the permanent magnet roller 7 by the inlet pipe 5, the contact area with the permanent magnet roller 7 is small, thereby reducing the adsorption effect of the permanent magnet roller 7. (Refer to...) Figure 2 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a dispersing mechanism 11 for dispersing liquid is connected to the upper end of the inside of the recycling box 1. The dispersing mechanism 11 includes a guide frame 111, which is fixedly connected to the upper end of the inside of the recycling box 1. The guide frame 111 is inclined downward toward the permanent magnet roller 7. Several buffer plates 112 are connected at equal intervals along the length direction at the bottom of the inside of the guide frame 111. Each buffer plate 112 is inclined upward. A baffle 113 is connected to the upper end of the inside of the recycling box 1. The baffle 113 is inclined downward toward the permanent magnet roller 7. A gap 114 is provided between the baffle 113 and the guide frame 111. The gap 114 is located above the permanent magnet roller 7. The liquid flowing out from the bottom of the inlet pipe 5 falls onto the guide frame 111 and comes into contact with the buffer plate 112. The buffer plate 112 buffers and temporarily stores the liquid, making it evenly dispersed on the entire surface of the guide frame 111. Subsequently, the liquid flows out from the bottom of the guide frame 111 and comes into full contact with the permanent magnet roller 7. Through the dispersing effect of the guide frame 111 and the buffer plate 112, the contact area between the liquid and the permanent magnet roller 7 increases, thereby improving the adsorption effect of the permanent magnet roller 7.

[0021] Example 4: After the filtered adsorbent is introduced into the filter chamber 4 through the discharge pipe 9, the introduced adsorbent contains a certain amount of salt water, thereby reducing the filtration effect. (Refer to...) Figure 2 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a filter mechanism 12 is connected inside the filter chamber 4. The filter mechanism 12 includes a collection rack 121, which is disposed inside the filter chamber 4 and located below the discharge pipe 9. A filter screen 122 is fixedly connected to the collection rack 121. A collection chamber 123 is provided between the filter screen 122 and the bottom end of the collection rack 121. A conduit 124 is connected to the collection chamber 123 and extends to the outside of the recycling box 1. The adsorbent released from the discharge pipe 9 falls onto the filter screen 122. The brine on the adsorbent passes through the filter screen 122 and falls into the collection chamber 123. The liquid in the collection chamber 123 flows from the conduit 124 through the filter screen 122 to filter the adsorbent, thereby improving the filtration effect.

[0022] Example 4: When the scraper 82 scrapes the adsorbent on the surface of the permanent magnet roller 7, some of the adsorbent will accumulate between the permanent magnet roller 7 and the scraper 82, thereby causing scratches on the surface of the permanent magnet roller 7. (Refer to...) Figure 5 As another preferred embodiment of this utility model, the difference from embodiment 2 is that the upper end of the partition 2 is connected to an anti-scraping mechanism 13 to prevent the adsorbent from accumulating between the permanent magnet roller 7 and the scraper 82. The anti-scraping mechanism 13 includes a limiting plate 131, which is fixedly connected to the upper end of the partition 2. An air pump 132 is fixedly connected to the upper end of the partition 2. The outlet end of the air pump 132 is connected to a dispersing pipe 134 through a connecting pipe 133. Several jet pipes 135 are connected along the length of the dispersing pipe 134. Each jet pipe 135 passes through the limiting plate 131 and is set towards the scraper 82. The diameter of the jet pipe 135 is smaller than the diameter of the dispersing pipe 134. The inlet end of the air pump 132 is connected to an air inlet pipe 136. After the air pump 132 is started, it draws gas through the air inlet pipe 136. The drawn gas is transported to the dispersion pipe 134 through the connecting pipe 133. The gas in the dispersion pipe 134 is sprayed out through several jet pipes 135 to purge the area between the permanent magnet roller 7 and the scraper 82, preventing the adsorbent from accumulating between the permanent magnet roller 7 and the scraper 82, thereby avoiding the scraper 82 from scratching the surface of the permanent magnet roller 7.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
