[0002] In the process of paper production, the papermaking pool is the main part of papermaking production equipment, usually a large shallow basin structure made of steel plates, reinforced concrete or plastic materials. Papermaking factories need to design pools with different sizes and quantities according to different paper uses to achieve different papermaking processes. For example, the fiber treatment methods required for draft paper and toilet paper are different, so different types of pools are needed; according to different pulping processes and papermaking processes, the pools can be divided into: straw pulp pools, coating pools, oxygen bleaching pools, washing pools, and drying pools; in order to keep the inside of the pool clean, it is generally necessary to clean the inside of the pool regularly to remove the sediment in the pool.

[0003] At present, for the cleaning of the above-mentioned pool body, generally, the liquid in the pool needs to be completely drained, and then workers go down into the pool to use tools such as shovels and scrapers to clean the inner wall of the pool body. This not only has a slow cleaning efficiency but also causes waste of the liquid in the pool. This article aims to propose a cleaning device for paper product production that does not require draining to clean the pool body. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when cleaning the pool body for papermaking in the prior art, generally, the liquid in the pool needs to be completely drained, and then workers go down into the pool to use tools such as shovels and scrapers to clean the inner wall of the pool body, resulting in a relatively slow cleaning efficiency, and to propose a cleaning device for paper product production.

[0022] Refer to the attached Figures 1-4 , a cleaning device for paper product production, including a pool body 1. An internal cavity with an upward opening is arranged in the pool body 1. Two symmetrically arranged lifting grooves 101 are communicated with the left and right sides of the internal cavity of the pool body 1. The inner bottom surface of the lifting groove 101 is lower than the inner bottom surface of the internal cavity of the pool body 1, and the inner width of the lifting groove 101 is greater than the inner width of the internal cavity of the pool body 1.

[0023] In this embodiment, object collecting fences 2 are installed in the two lifting grooves 101 in a lifting manner. The object collecting fence 2 includes a bottom plate 201, an outer baffle 202, and two side plates 203. The lower end of the outer baffle 202 is integrally and fixedly connected to one side of the bottom plate 201. The outer baffle 202 is in close contact with the left or right side wall of the internal cavity of the pool body 1. The two side plates 203 are respectively vertically and fixedly installed on the front and rear sides of the bottom plate 201. The outer side end surfaces of the two side plates 203 are respectively in close contact with the inner walls of the lifting grooves 101. The inner side end surfaces of the two side plates 203 are respectively on the same vertical plane as the front and rear inner walls of the internal cavity of the pool body 1, that is, the inner width of the object collecting fence 2 is the same as the inner width of the internal cavity of the pool body 1. The bottom plate 201 is installed in the lifting groove 101 in a lifting manner.

[0024] In this embodiment, a dredging mechanism 5 is slidably installed in the pool body 1 through the guide mechanism 3. The dredging mechanism 5 includes a scraper 1 501 and two scrapers 2 503 for scraping off sediment, attachments and other foreign objects. The lower ends of the two scrapers 2 503 are respectively and vertically fixedly installed on both sides of the scraper 1 501, so that the scraper 1 501 and the two scrapers 2 503 form a U shape. The lower surface of the scraper 1 501 and the bottom surface of the built-in cavity of the pool body 1 are in contact with each other, and triangular blades 1 502 are provided on both sides of the bottom of the scraper 1 501. The triangular blades 1 502 are mainly used to increase the shear force of the scraper 1 501, so as to better scrape off foreign objects on the bottom surface of the built-in cavity of the pool body 1.

[0025] The two scrapers 503 are also in contact with the front and rear side walls of the built-in cavity of the pool body 1 respectively, and triangular blades 504 are provided on the left and right sides of the contact part between the scraper 503 and the wall of the built-in cavity of the pool body 1, so as to facilitate scraping away impurities on the front and rear side walls of the built-in cavity of the pool body 1, that is, when the dredging mechanism 5 moves left and right along the pool body 1 through the guide mechanism 3, the scraper 1 501 and the two scrapers 503 will scrape away foreign objects on the forward side of the dredging mechanism 5.

[0026] In this embodiment, a rectangular baffle frame 506 is fixedly installed in the inner circle of the scraper 1 501 and the two scraper 2s 503 forming a U-shaped state. The rectangular baffle frame 506 is mainly used to block the foreign matter scraped by the scraper 1 501 and the scraper 2 503, and to precipitate the scraped foreign matter as much as possible on the side of the direction in which the dredging mechanism 5 moves to scrape away the foreign matter. Two layers of the pool filter 4 are fixedly filled and installed in the rectangular baffle frame 506. A cross bar 505 is fixedly installed in the middle of the pool filter 4. The cross bar 505 and the rectangular baffle frame 506 are fixedly connected. The pool filter 4 is mainly used to filter solid foreign matter that is larger than the inner hole size of the pool filter 4 through liquids such as water.

[0027] In this embodiment, the guide mechanism 3 includes two parallel slide rails 304, two connecting seats 301, and a connecting block 303. The connecting block 303 is fixedly installed directly above the rectangular baffle frame 506. The two connecting seats 301 are fixedly installed at the front and rear ends of the connecting block 303 by two bolts respectively. The two slide rails 304 are symmetrically and horizontally fixedly installed on the outer walls of the pool body 1 on both sides. Three pulleys 302 are rotatably installed on the inner side of the connecting seat 301 through a wheel frame. The three pulleys 302 are arranged in an isosceles triangle and are horizontally slidably installed on a slide rail 304.

[0028] It should be further noted that a perforation 305 is provided at the middle end of the connecting block 303. The perforation 305 in the connecting block 303 is mainly used for threading a rope, which facilitates the worker to thread the rope and pull the connecting block 303 and the dredging mechanism 5 to move along the two sliding rails 304 on the outer wall of the pool body 1. Similarly, for the collection bin 2 to facilitate better lifting operation by the worker, a number of grip holes 204 are also provided on the two side plates 203 of the collection bin 2. Through the grip holes 204 on the side plates 203, it is convenient for the worker to hold the collection bin 2 by hand for lifting and lowering;

[0029] It is further supplemented and explained that in addition to the above manual driving operation for the movement of the dredging mechanism 5 and the collection bin 2, it can also be driven by adding a lifting oil cylinder in the prior art. For example, the outer shell of the lifting oil cylinder is fixedly installed parallel to the pool body 1, and the end of the piston rod in the lifting oil cylinder is fixedly connected to the connecting block 303 in the guiding mechanism 3. Then, through the telescopic movement of the piston rod in the lifting oil cylinder and being transmitted by the connecting block 303, the dredging mechanism 5 can move left and right along the inner wall of the pool body 1. If the outer shell of another lifting oil cylinder is fixedly installed vertically on the pool body 1 and the top end of the piston rod of this lifting oil cylinder is fixedly connected to the collection bin 2, the lifting and lowering of the collection bin 2 can be driven by the telescopic movement of the piston rod in this lifting oil cylinder.

[0030] In the present utility model, when the pool body 1 is in a normal state, such as Figure 1 , the dredging mechanism 5 is located inside one of the collection bins 2, that is, the dredging mechanism 5 is located on one side of the internal cavity of the pool body 1 and will not affect the normal operation of the pool body 1;

[0031] When it is necessary to clean the internal cavity of the pool body 1, the worker pulls the connecting block 303 and the dredging mechanism 5 to move along the two sliding rails 304 on the outer wall of the pool body 1 by threading a rope, moving away from the outer collection bin 2 and gradually approaching the other collection bin 2. During the movement of the dredging mechanism 5, the first scraper 501 and the two second scrapers 503 in the dredging mechanism 5 will scrape off foreign matters on the bottom surface and the front and rear side walls of the internal cavity of the pool body 1, and the double-layer pool filter screen 4 will filter large particle impurities in the passing liquid and concentrate them and push them towards the gradually approaching collection bin 2 until the triangular blade two 504 in the dredging mechanism 5 coincides with the edge of the other lifting groove 101 and then stops. At this time, the state of the dredging mechanism 5 is as shown in Figure 4 , the dredging mechanism 5 cooperates with the pool filter screen 4 to concentrate the scraped and filtered foreign matters directly above the adjacent collection bin 2. After a period of precipitation, the foreign matters will gradually sink to the bottom plate 201 in the collection bin 2. Then, the worker manually lifts the collection bin 2 to move the foreign matters collected in the collection bin 2 upward. Refer to Figure 2 , that is, raising the outer baffle 202 of the collection bin 2 to the part at the upper edge of the pool body 1 makes it easier for the worker to clean the things in the collection bin 2. It is also possible to bend and take out the collection bin 2 for cleaning. After cleaning, the collection bin 2 is put back into the lifting groove 101, and at the same time, the dredging mechanism 5 is moved into the cleaned collection bin 2.

[0032] It can be seen that the silt cleaning mechanism 5 and the pool filter screen 4 are the main structures for cleaning the built-in cavity of the pool body 1. The two debris collection bins 2 are mainly used to collect the foreign objects scraped and filtered by the silt cleaning mechanism 5 and the pool filter screen 4, facilitating the discharge of foreign objects. Therefore, in addition to setting the lifting grooves 101 and the debris collection bins 2 on both sides of the built-in cavity of the pool body 1, a gate in a lifting state can also be set. The gate is vertically installed above the built-in cavity of the pool body 1. Whenever the silt cleaning mechanism 5 and the pool filter screen 4 push the foreign objects to one side of the built-in cavity of the pool body 1, the liquid in the built-in cavity of the pool body 1 is separated by lowering the gate. One side is the liquid with a large amount of foreign objects, and the other side is the cleaned liquid. For reference, see Figure 4 , the gate is vertically lifted in Figure 4 the right side adjacent to the pool filter screen 4 in the middle pool. At this time, only by pumping with a sewage pump or setting a sewage outlet to discharge the liquid with a large amount of foreign objects can the purpose of cleaning the built-in cavity of the pool body 1 be achieved.

[0033] In this utility model, by moving the silt cleaning mechanism 5 and the pool filter screen 4 to the left or right, the foreign objects can be scraped and filtered. Then, in cooperation with the debris collection bin 2, the scraped and filtered foreign objects are collected, and the debris collection bin 2 is lifted upward to expose the scraped and filtered foreign objects above the liquid surface. Workers can achieve the purpose of cleaning the built-in cavity of the pool body 1 without getting into the water or draining the water in the built-in cavity of the pool body 1. Moreover, cleaning the debris collection bin 2 greatly reduces the space for cleaning foreign objects compared with cleaning the entire built-in cavity of the pool body 1, thereby improving the cleaning efficiency, making the cleaning more efficient. Or the liquid in the built-in cavity of the pool body 1 is separated by the gate, with one side being the liquid with a large amount of foreign objects and the other side being the cleaned liquid, reducing the required built-in cavity of the pool body 1 to be cleaned, which can also save manpower and does not require completely draining the liquid in the built-in cavity of the pool body 1.

[0034] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
