Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, to a novel pressing device with high dehydration performance. Background Technology

[0002] The paper press is one of the key pieces of equipment in the papermaking process. It uses powerful mechanical pressure to further compress the initially dehydrated wet paper sheet, removing residual moisture and thus improving the paper's dryness and density. This process not only enhances the paper's strength and smoothness but also helps reduce energy consumption in subsequent drying processes, improving papermaking efficiency and paper quality.

[0003] Belt presses are classified in various ways. One type mainly consists of a drive unit, frame, press rollers, upper filter belt, lower filter belt, filter belt tensioning device, filter belt cleaning device, unloading device, pneumatic control system, and electrical control system. The dewatering process of a belt press can be divided into four important stages: pretreatment, gravity dewatering, wedge zone pre-compression dewatering, and pressing dewatering.

[0004] The dewatering efficiency of a belt press largely depends on the properties of the filter belt. If the mesh on the filter belt becomes clogged, the dewatering efficiency will be affected. Therefore, most existing technologies use filter belt cleaning devices to rinse the filter belt. Although rinsing can effectively clean the filter belt, it generates a large amount of wastewater, resulting in water waste. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of pressing device with high dehydration performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel pressing device with high dehydration capacity, comprising a housing, a cleaning port at one end of the housing, a brush roller rotatably connected inside the housing and located at the cleaning port, one end of the brush roller being drivenly connected to the output shaft of a motor via a coupling, the motor being mounted on the housing, and multiple exhaust fans installed at the end of the housing away from the cleaning port, the air inlets of the multiple exhaust fans communicating with the interior of the housing, and the air outlets of the multiple exhaust fans communicating with the exterior of the housing.

[0007] Preferably, a filter screen is fixedly connected inside the housing and between the cleaning port and the multiple exhaust fans.

[0008] Preferably, a horizontal shaft is rotatably connected to the housing, and multiple bridges are fixedly connected to the horizontal shaft. A lever is fixedly connected to one end of each bridge away from the horizontal shaft, and the levers rub against the filter screen. A collection box is slidably connected to the housing, and the opening of the collection box communicates with the interior of the housing. A first scraper is fixedly connected to the inner wall of the housing at the opening of the collection box.

[0009] Preferably, one end of the brush roller is fixedly connected to a first pulley, the first pulley is connected to a second pulley via a belt drive, and the second pulley is fixedly connected to one end of the horizontal shaft.

[0010] Preferably, handles are fixedly connected to both ends of the collection box.

[0011] Preferably, a second scraper is fixedly connected to the inner wall of the housing, and the second scraper rubs against the brush roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The brush roller is driven by a motor to rotate. The end of the brush roller that extends out of the cleaning port contacts the filter belt on the belt press. The rotating brush roller can clean the filter belt and send the cleaned impurities into the housing. Multiple exhaust fans can suck the impurities cleaned by the brush roller into the housing to prevent the impurities from falling back onto the filter belt. This application effectively solves the problem of generating a large amount of wastewater and wasting water resources by using the brush roller to clean the filter belt in the prior art.

[0014] 2. The filter screen intercepts impurities drawn into the housing. The horizontal shaft drives multiple bridges and their paddles to rotate. When the paddles rotate to contact the filter screen, they scrape off the impurities. When the paddles rotate to contact the first scraper, the first scraper scrapes off the impurities on the paddles, causing them to fall into the collection box, thus completing the collection of impurities.

[0024] Reference Figures 1 to 3This utility model provides a technical solution: a novel pressing device with high dehydration capacity, comprising a housing 1. The housing 1 can be mounted on a belt press using existing brackets, thereby replacing the original cleaning device on the belt press for cleaning the filter belt. One end of the housing 1 has a cleaning port 2. A brush roller 3 is rotatably connected inside the housing 1 and located at the cleaning port 2. One end of the brush roller 3 is connected to the output shaft of a motor 4 via a coupling. The motor 4 is mounted on the housing 1 and can drive the brush roller 3 to rotate. Figure 2 The brush roller 3 extends out of the cleaning port 2 and contacts the filter belt on the belt press. The counter-clockwise rotating brush roller 3 cleans the filter belt and sends the cleaned impurities into the housing 1. Multiple exhaust fans 5 are installed at the end of the housing 1 away from the cleaning port 2. The air inlets of the multiple exhaust fans 5 are connected to the interior of the housing 1, and the air outlets of the multiple exhaust fans 5 are connected to the exterior of the housing 1. Figure 1 and Figure 2 Multiple exhaust fans 5 can suck the impurities cleaned by the brush roller 3 into the housing 1, preventing the impurities from falling back onto the filter belt.

[0025] This application uses a brush roller 3 to clean the filter belt, effectively solving the problem that the existing technology of using rinsing will generate a large amount of sewage and waste water resources.

[0026] Specifically, a filter 6 is fixedly connected inside the housing 1, between the cleaning port 2 and the multiple exhaust fans 5, such as... Figure 2 The filter 6 intercepts impurities drawn into the housing 1.

[0027] Specifically, a horizontal shaft 7 is rotatably connected to the housing 1, and multiple cable trays 8 are fixedly connected to the horizontal shaft 7. A lever 9 is fixedly connected to the end of each cable tray 8 away from the horizontal shaft 7. Figure 3 The horizontal axis 7 can drive multiple bridges 8 and the paddles 9 on them to rotate. The paddles 9 are made of a deformable material, such as rubber. All of the paddles 9 rub against the filter screen 6. A collection box 10 is slidably connected to the housing 1. The opening of the collection box 10 communicates with the interior of the housing 1. A first scraper 11 is fixedly connected to the inner wall of the housing 1 and located at the opening of the collection box 10.

[0028] like Figure 2 When the paddle 9 rotates to contact the filter screen 6, the paddle 9 can scrape off the impurities on the filter screen 6. When the paddle 9 rotates to contact the first scraper 11, the first scraper 11 can scrape off the impurities on the paddle 9, and the scraped impurities fall into the collection box 10, thus completing the collection of impurities.

[0029] Specifically, one end of the brush roller 3 is fixedly connected to a first pulley 12, and the first pulley 12 is driven by a second pulley 14 via a belt 13. The second pulley 14 is fixedly connected to one end of the horizontal shaft 7. Figure 1 The brush roller 3 can drive the first pulley 12 to rotate. The first pulley 12 drives the second pulley 14 to rotate through the belt 13. The second pulley 14 drives the horizontal shaft 7 to rotate. The belt 13 adopts a cross-drive method, so that the horizontal shaft 7 and the brush roller 3 rotate in opposite directions.

[0030] Specifically, handles 15 are fixedly connected to both ends of the collection box 10, such as... Figure 1 The handle 15 allows the collection box 10 to be easily pulled out of the housing 1 for cleaning.

[0031] Specifically, a second scraper 16 is fixedly connected to the inner wall of the housing 1, and the second scraper 16 rubs against the brush roller 3, such as... Figure 2 The second scraper 16 can scrape off the impurities on the brush roller 3, preventing the impurities from sticking to the brush roller 3.

[0032] Working principle: The motor 4 drives the brush roller 3 to rotate. One end of the brush roller 3 extends out of the cleaning port 2 and contacts the filter belt on the belt press. The rotating brush roller 3 can clean the filter belt and send the cleaned impurities into the housing 1. Multiple exhaust fans 5 can suck the impurities cleaned by the brush roller 3 into the housing 1 to prevent the impurities from falling back onto the filter belt. This application effectively solves the problem of generating a large amount of wastewater and wasting water resources by cleaning the filter belt with the brush roller 3 in the prior art.
