Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, to an internal flow front screen that is not easily clogged. Background Technology

[0002] Papermaking is an important invention of the ancient Chinese working people. There are many pulp screening devices in the existing technology, such as internal flow pressure screens, external flow pressure screens, and centrifugal screens, all of which can achieve the function of screening pulp. The mechanism is carried out continuously on the paper machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and then initially dewatered in the wire section of the paper machine to form a wet sheet. After pressing and dewatering, it is dried into paper. However, the existing equipment has poor slag removal effect, and most of it requires regular cleaning by staff, which is time-consuming, labor-intensive, and inefficient. To solve the above problems, we have introduced the following device. Utility Model Content

[0011] Beneficial effects

[0013] 1. This non-clogging internal flow screen, by setting up a guide block, a first motor, a threaded column and a threaded cap, when it is necessary to clean the waste residue on the guide block, the first motor is operated, and with the cooperation of the threaded column and the threaded cap, the rectangular cylinder is moved, thereby driving the scraper to clean the waste residue on the guide block and push the waste residue out of the box. Since the inclined scraper can squeeze the spring upward through the top rod and the movable plate, it can ensure that the scraper is always in contact with the surface of the guide block, resulting in a better cleaning effect and improved cleaning efficiency;

[0014] 2. This non-clogging internal flow screen, by setting up a second motor, a third rotating shaft, a first screen drum, and a second screen drum, allows the second motor to operate when a pressure difference is needed between the first and second screen drums. This, in turn, drives the third rotating shaft to rotate. The third rotating shaft and the third bearing work together to rotate the first and second screen drums, simultaneously driving a belt drive that rotates two sets of rotors. The rotors rotate at high speed around the first screen drum, generating centrifugal force. Large particles of impurities in the pulp entering the chamber are separated from the pulp upon entering the surface of the first screen drum and fall onto the guide block surface. Under the pressure difference across the first screen drum, the pulp enters the inner cavity of the first screen drum, and then flows into the inner cavity of the second screen drum. Small particles of impurities in the pulp are filtered on the surface of the second screen drum. This completes the impurity removal process, thus improving the practicality of the device.

[0026] By adopting the above technical solution, this non-clogging internal flow screen, through the setting of guide block 12, first motor 13, threaded column 17 and threaded cap 21, when people need to clean the waste residue on guide block 12, people control the operation of first motor 13, and with the cooperation of threaded column 17 and threaded cap 21, drive rectangular cylinder 4 to move, thereby driving scraper 11 to clean the waste residue on guide block 12 and push the waste residue out into box 2. Since the inclined scraper 11 can squeeze spring 6 upward through top rod 10 and movable plate 7, it can ensure that scraper 11 is always in contact with the surface of guide block 12, resulting in better cleaning effect and improved cleaning efficiency.

[0027] Specifically, a motor bracket 24 is fixedly connected to the upper surface of the housing 2. A second motor 25 is installed inside the motor bracket 24.

A belt 33 is movably connected to the surface of the rotating wheels 28. The three sets of rotating wheels 28 are rotatably connected to each other through the belt 33.

[0029] By adopting the above technical solution, this non-clogging internal flow screen, through the configuration of a second motor 25, a third rotating shaft 26, a first screen drum 29, and a second screen drum 30, allows for the generation of a pressure difference between the first screen drum 29 and the second screen drum 30 when a pressure difference is desired. This is achieved by controlling the second motor 25 via a control switch 48, which in turn drives the third rotating shaft 26. The cooperation of the third rotating shaft 26 and the third bearing 27 enables the rotation of the first screen drum 29 and the second screen drum 30, simultaneously driving the belt 33 to drive the two sets of rotors. When rotor 34 rotates, it generates centrifugal force by rotating at high speed around the first screen drum 29. At this time, large particles of impurities in the pulp entering the housing 2 are separated from the pulp when they enter the surface of the first screen drum 29 and fall onto the surface of the guide block 12. Then, under the action of the pressure difference on both sides of the first screen drum 29, the pulp enters the inner cavity of the first screen drum 29, and then enters the inner cavity of the second screen drum 30 through the first screen drum 29. Small particles of impurities in the pulp are filtered on the surface of the second screen drum 30. The pulp after impurity removal is completed, thereby improving the practicality of the device.

[0030] Specifically, a water storage tank 37 is fixedly connected to the upper surface of the tank 2, a connecting pipe 38 is fixedly connected to the side of the water storage tank 37, a water pump 39 is fixedly connected to the other end of the connecting pipe 38, the water pump 39 is fixedly connected to the upper surface of the tank 2, a hose 40 is fixedly connected to the water outlet end of the water pump 39, a through hole 23 is opened on the side of the tank 2, the hose 40 passes through the through hole 23, a water outlet pipe 41 is fixedly connected to the other end of the hose 40, the water outlet pipe 41 is fixedly connected to the inside of the tank 2, and a nozzle 42 is fixedly connected to the lower surface of the water outlet pipe 41.

[0031] Specifically, a slurry inlet pipe 43 is fixedly connected to the side of the box body 2, and a flow meter 44 is fixedly connected to the other end of the slurry inlet pipe 43. A slag discharge port 45 is opened on the side of the box body 2. A first movable door 46 is fixedly connected to the side of the box body 2.

[0032] The working principle of this utility model is as follows: During use, pulp is conveyed into the housing 2 through the pulp inlet pipe 43 and the liquid flow meter 44. At this time, the user controls the operation of the second motor 25 through the control switch 48, thereby driving the third rotating shaft 26 to rotate. With the cooperation of the third rotating shaft 26 and the third bearing 27, the first screen drum 29 and the second screen drum 30 are rotated. At the same time, the belt 33 drives the two sets of rotors 34 to rotate. At this time, the rotors 34 rotate at high speed around the first screen drum 29, generating centrifugal force. At this time, large particles of impurities in the pulp entering the housing 2 are separated from the pulp when they enter the surface of the first screen drum 29 and fall onto the surface of the guide block 12. At this time, the pulp enters the inner cavity of the first screen drum 29 under the action of the pressure difference on both sides of the first screen drum 29, and then enters the inner cavity of the second screen drum 30 through the first screen drum 29. Small particles of impurities in the pulp are filtered on the surface of the second screen drum 30. At this time, the pulp after impurity removal flows out from the second screen drum 30 through the pulp outlet pipe 31. When the pulp enters the first screen drum 29, impurities in the pulp are blocked by the first screen drum 29 and fall onto the surface of the guide block 12. When it is necessary to clean the waste residue on the guide block 12, the first motor 13 is operated by controlling the operation of the first motor 13. With the cooperation of the threaded column 17 and the threaded cap 21, the rectangular cylinder 4 is moved, which in turn drives the scraper 11 to clean the waste residue on the guide block 12 and push the waste residue out of the box 2. Since the inclined scraper 11 can pass upward through the top rod 10 and the movable plate 7. The compression spring 6 ensures that the scraper 11 is always in contact with the surface of the guide block 12. The scraper 11 pushes the pulp out of the box 2. At this time, the light impurities in the pulp are discharged through the slag discharge port 45 under the action of the airflow. After the impurity removal is completed, the user turns on the water pump 39. The water pump 39 transmits the clean water in the water storage tank 37 to the water outlet pipe 41 through the hose 40. The nozzle 42 washes the surface of the first screen drum 29 and the second screen drum 30. The wastewater after washing is discharged through the slag discharge port 45.
