Description

Technical Field

[0001] The utility model relates to the field of pulp manufacturing, in particular to a pulp filtering device. Background Art

[0002] Pulp needs to be filtered before drying. Pulp filtering can reduce impurities in the pulp. Reducing the content of impurities can improve the quality of the pulp and increase the fluidity of the pulp. Reducing the impurity content of paper can improve the friction and wear resistance of the paper.

[0003] Currently, most pulp is filtered through a filter. This method requires workers to clean or replace the filter element at regular intervals. Excessive impurities or impurities that are difficult to remove on the filter element will reduce the quality of filtration to a certain extent. Utility Model Content

[0004] In order to overcome the shortcomings that the current pulp filtering requires staff to clean and replace the filter screen, and too many impurities in the filter screen will reduce the quality of the pulp, the utility model provides a pulp filtering device that can easily remove impurities on the filter screen and can clean impurities that are difficult to remove.

[0005] The technical solution of the utility model is: a pulp filtering device, including a slide rail frame, a filter barrel is fixedly connected to the top of the slide rail frame, an electric push rod is fixedly connected to the slide rail frame, two electric sliders are slidably connected to the slide rail frame, the two electric sliders are symmetrically arranged, a filter screen is installed between the two electric sliders, a lower pressure frame is fixedly connected to the telescopic rod of the electric push rod, and a scraping mechanism for scraping impurities on the surface of the filter screen is provided on the lower pressure frame.

[0006] In one embodiment, the scraping mechanism includes a scraping frame, the scraping frame is slidably connected to the lower pressure frame, a dust suction pipe is fixedly connected to the top of the scraping frame, and a return spring is connected between the lower pressure frame and the scraping frame.

[0007] In one of the embodiments, a corrugated plate is also included, and two corrugated plates are slidably connected to the bottom of the scraper frame, and the two corrugated plates are symmetrically arranged. Four tension springs are connected between the scraper frame and each of the corrugated plates, and two guide grooves are opened on each of the corrugated plates, and the two guide grooves are symmetrically arranged. Limit rods are slidably connected to both sides of each of the corrugated plates, and the limit rods are slidably connected to the guide grooves, and each of the limit rods is in contact with the inner wall of the lower pressure frame.

[0008] In one of the embodiments, a funnel is further included, and the funnel is installed at the bottom of the slide rail frame.

[0009] In one of the embodiments, two handles are provided on the upper portion of the scraper frame.

[0010] The beneficial effects are: 1. The filter screen is driven to rotate by the electric slider, and the electric push rod is started to drive the lower pressure frame to move downward, which can leave impurities in the pulp on the filter screen, and the clean pulp will be squeezed through the filter screen. After adjusting the electric push rod to move upward, the scraper frame in the lower pressure frame is pressed down separately, which can clean the impurities remaining after filtering after squeezing the pulp, which is faster than manual cleaning by the staff and improves work efficiency.

[0011] 2. The tension spring will reset and drive the corrugated plate to move downward. The two limit rods on the same corrugated plate will move away from each other along the guide groove. The corrugated plate extends from the scraper frame and contacts the filter screen, which can make the filter screen cleaner after each filtering of the pulp, so that the next filtration will not be blocked, thereby improving the quality of pulp filtration and preventing clean pulp from being left on the filter screen to be cleaned, thereby reducing the waste of pulp.

DETAILED DESCRIPTION

[0019] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] A pulp filtering device, such as Figure 1-Figure 2As shown, it includes a slide rail frame 1, a filter barrel 2 is fixedly connected to the top of the slide rail frame 1, an electric push rod 3 is fixedly connected to the slide rail frame 1, two electric sliders 31 are slidably connected to the slide rail frame 1, the two electric sliders 31 are symmetrically arranged, a filter screen 4 is installed between the two electric sliders 31, the filter screen 4 is used to filter impurities in the pulp to improve the quality of the pulp, a lower pressure frame 5 is fixedly connected to the telescopic rod of the electric push rod 3, and a scraping mechanism for scraping impurities on the surface of the filter screen 4 is provided on the lower pressure frame 5.

[0022] The scraping mechanism includes a scraping frame 6, which is slidably connected to the lower pressure frame 5. The scraping frame 6 can scrape and gather impurities on the filter screen 4. A dust suction pipe 61 is fixedly connected to the top of the scraping frame 6, and a return spring 7 is connected between the lower pressure frame 5 and the scraping frame 6.

[0023] The staff first pours the pulp into the filter barrel 2, then starts the electric slider 31 to rotate the filter screen 4, and then starts the electric push rod 3. The telescopic rod of the electric push rod 3 extends to drive the lower pressure frame 5 to move downward, thereby squeezing the pulp in the filter barrel 2. When the lower pressure frame 5 squeezes the pulp, the filter screen 4 rotates to leave impurities in the pulp on the filter screen 4, and the clean pulp will be squeezed through the filter screen 4. Then the staff adjusts the electric push rod 3 to make the telescopic rod of the electric push rod 3 shrink, and then the staff removes the impurities on the filter screen 4.

[0024] After the telescopic rod of the adjustment push rod is extended, the worker holds the scraper frame 6 and presses it downward, the reset spring 7 is stretched, so that the scraper frame 6 contacts the filter screen 4, scrapes and gathers the impurities on the filter screen 4, and then the dust suction pipe 61 sucks the impurities out of the scraper frame 6. Finally, the worker releases the scraper frame 6, and the reset spring 7 resets and drives the scraper frame 6 to reset, and the scraper frame 6 in the pressing frame 5 is pressed down alone, so that the impurities remaining after filtering can be cleaned after squeezing the pulp, which is faster than manual cleaning by the worker and improves the work efficiency.

[0025] Example 2

[0026] On the basis of Example 1, Figure 3-Figure 6 As shown, it also includes a corrugated plate 8, and two corrugated plates 8 are slidably connected to the bottom of the scraper frame 6, and the two corrugated plates 8 are symmetrically arranged. The corrugated plates 8 are made of hard rubber and are used to scrape impurities that are difficult to clean on the filter screen 4. Four tension springs 9 are connected between the scraper frame 6 and each of the corrugated plates 8. Two guide grooves 10 are opened on each of the corrugated plates 8, and the two guide grooves 10 are symmetrically arranged. Limit rods 11 are slidably connected to both sides of each of the corrugated plates 8, and the limit rods 11 are slidably connected to the guide grooves 10, and each of the limit rods 11 is in contact with the inner wall of the lower pressure frame 5.

[0027] A funnel 12 is also included. The funnel 12 is installed at the bottom of the slide rail frame 1.

[0028] Two handles are provided on the upper portion of the scraping frame 6 .

[0029] Initially, the tension spring 9 is in a compressed state, and the limit rod 11 is blocked by the lower pressure frame 5 in the scraper frame 6. When the scraper frame 6 moves downward, the lower pressure frame 5 will not block the limit rod 11, so that the limit rod 11 can move, and the tension spring 9 will reset to drive the corrugated plate 8 to move downward. The two limit rods 11 on the same corrugated plate 8 will move away from each other along the guide groove 10. The corrugated plate 8 extends from the scraper frame 6 and contacts the filter screen 4. The corrugated plate 8 will scrape the impurities or sticky impurities stuck on the filter screen 4. When the staff releases the scraper frame 6 When the scraper frame 6 moves upward, the lower pressure frame 5 will squeeze the two limit rods 11 on the same corrugated plate 8 to move in a direction close to each other, thereby driving the corrugated plate 8 to move upward, and the corrugated plate 8 will compress the tension spring 9 again. When the scraper frame 6 moves downward, the corrugated plate 8 is extended at the same time to scrape the impurities on the surface that are difficult to scrape off, which can make the filter screen 4 cleaner after filtering the pulp each time, so that the next filtration will not be blocked, thereby improving the quality of pulp filtration and preventing clean pulp from being left on the filter screen 4 and being cleaned, thereby reducing waste.

[0030] After the pulp is squeezed by the lower pressing frame 5 , the funnel 12 is convenient for collecting the pulp below the filter screen 4 .

[0031] The handle can facilitate the staff to press the scraping frame 6 downwards.

[0032] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention.
