Description

Technical Field

[0001] This application belongs to the field of pulp screening machine technology, and particularly relates to a pressure pulp screening machine for papermaking. Background Technology

[0002] Papermaking is an important invention of the ancient Chinese working people. It has two forms: machine-made and handmade. Machine-made papermaking is a continuous process on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, initially dewatered on the wire section of the papermaking machine to form a wet sheet, then further dewatered by pressing, and finally dried to form paper. A screening machine separates the pulp from the cellulose.

[0003] A Chinese patent with publication number CN111254733B discloses a pressure pulping machine for papermaking, belonging to the field of pulping machine technology. It includes a base and a housing with a discharge port. The lower end of the housing and the upper end of the base are rotatably connected via a coarse rotating shaft. A filtering mechanism is provided on the upper side of the housing, comprising a first filter screen, a second filter screen, and a third filter screen, which are equidistant from top to bottom. The filtering mechanism is connected to a telescopic connecting mechanism to achieve its vertical linear movement. The filtering mechanism can also move through the upper side of the housing to its interior. The telescopic connecting mechanism includes a connecting rod, which is fixed between the first, second, and third filter screens for fixation. The telescopic connecting mechanism is connected to a screw and nut transmission mechanism to achieve the left-right linear movement of the filtering mechanism.

[0004] Although the aforementioned pulp screening machine can clean the filter screen, it cannot do so automatically, resulting in low cleaning efficiency. Improvements are needed to address this issue. Utility Model Content

[0005] The purpose of this application is to address the aforementioned technical problems by providing a pressure screening machine for papermaking that can automatically clean the filter screen and improve cleaning efficiency.

[0006] This application provides a pressure screening machine for papermaking, comprising:

[0007] The base is equipped with a shell;

[0008] The first drive mechanism is used to drive the housing to rotate;

[0009] The filtration mechanism is adapted to the housing and is equipped with several filter screens;

[0010] The second drive mechanism is installed and connected to the filter mechanism and is used to drive the filter mechanism to move up and down and horizontally.

[0011] The cleaning mechanism is located on one side of the housing and is adapted to the corresponding filter mechanism;

[0012] The base is provided with a support column, the second drive mechanism is installed on the support column, the cleaning mechanism is installed on the support column, and the cleaning mechanism includes a cleaning chamber and a cleaning brush.

[0013] The first drive mechanism is mounted on the base, and the housing is movably mounted on the base. The first drive mechanism and the housing are connected by a motor and gears. The first drive mechanism drives the housing to rotate. The support column is mounted on the base, and the second drive mechanism is mounted on the support column. The second drive mechanism and the filter mechanism are connected by a lead screw, threaded seat, motor, and cylinder. The second drive mechanism drives the filter mechanism to move up and down and horizontally, and controls the filter mechanism to move between the housing and the cleaning mechanism. The filter mechanism filters the residue through a filter screen, which is arranged in sequence with several filter screens of different mesh sizes. The cleaning mechanism is mounted on the support column and located on the side of the housing. When the filter mechanism needs cleaning, it moves from the housing towards the cleaning chamber. The cleaning brush cleans the filter mechanism, and the residue is collected by the cleaning chamber and then diverted to other collection equipment.

[0014] Furthermore, the cleaning mechanism also includes:

[0015] Several nozzles are installed in the cleaning chamber;

[0016] The movable shaft is installed and connected to the cleaning brush and is also movably connected to the cleaning chamber.

[0017] The first motor is connected to the movable shaft;

[0018] The movable panel is mounted on the cleaning chamber.

[0019] The lower nozzle is installed in the cleaning chamber. Water is sprayed from the bottom up through the lower nozzle. The water flows through the filter screen and quickly separates the debris on the surface of the filter screen from the filter screen, making it easier for the cleaning brush to separate the debris from the filter screen. The movable shaft and the cleaning brush are installed and connected. The first motor controls the rotation of the movable shaft, thereby controlling the rotation of the cleaning brush around the movable shaft. It is easy to control the cleaning brush to move away from or closer to the filter screen. The movable plate facilitates the cooperation between the filtration mechanism and the cleaning chamber, ensuring that the water flowing down the filter screen can be collected by the cleaning chamber. The movement of the movable plate is controlled by a cylinder.

[0020] Furthermore, the filtration mechanism includes:

[0021] Shaft body;

[0022] The filter screen is mounted on the shaft.

[0023] The shaft is connected to the second drive mechanism, and the filter screens are all installed and connected to the shaft to ensure the overall structural stability of the filtration mechanism and facilitate the movement of the filter screens.

[0024] Furthermore, the cleaning mechanism also includes:

[0025] The abutment seat is located on the underside of the cleaning chamber;

[0026] The drive unit is movably mounted on the abutment seat;

[0027] The second motor is connected between the abutment seat and the drive seat;

[0028] The shaft is provided with a first limiting groove, the drive seat is provided with a first limiting part, the cleaning chamber is provided with a rotating hole, the rotating hole is formed by a movable plate, and the rotating hole is provided with a sealing element.

[0029] The abutment seat is placed on the lower side of the cleaning chamber, and the drive seat is hinged to the abutment seat, so that the shaft moves into the rotating hole and is placed above the abutment seat. Then it moves downward so that the first limiting part on the drive seat cooperates with the first limiting groove of the shaft. The shaft is driven to rotate by the second motor, so that the cleaning brush can clean the filter screen. The rotating hole and the sealing element improve the sealing between the shaft and the cleaning chamber.

[0030] Furthermore, the cleaning mechanism also includes:

[0031] The first drive cylinder is positioned between the abutment seat and the cleaning chamber;

[0032] Ball joint seat, mounted on the shaft;

[0033] The locking mechanism is located on the shaft and corresponds to the ball joint seat;

[0034] The abutment seat is hinged to the cleaning chamber.

[0035] The first drive cylinder controls the abutment seat to rotate around the hinge axis. Through the cooperation of the ball joint seat, the shaft body is tilted by 5-10°, which facilitates the flow of water from the filter screen into the cleaning chamber. The movable plate moves and cooperates with the shaft body after the shaft body is tilted. The locking mechanism is used to lock the ball joint seat and the shaft body. After cleaning is completed, the locking mechanism is used to lock the ball joint seat and the shaft body again. Both ends of the ball joint seat are connected to the shaft body by ball joints. The middle of the ball joint seat has a telescopic structure, which can adjust the distance between the two ends of the ball joint seat.

[0036] Furthermore, the locking mechanism includes:

[0037] The locking sleeve is provided with a second limiting groove;

[0038] The first spring is placed between the locking sleeve and the shaft.

[0039] The second limiting part is placed on the shaft and is adapted to the second limiting groove;

[0040] The cleaning chamber is equipped with a toggle seat, which is moved by a cylinder, and the locking sleeve is equipped with a flange corresponding to the toggle seat.

[0041] The locking sleeve abuts against the first spring. When the actuating seat and the flange on the locking sleeve are engaged, the cylinder controls the movement of the actuating seat and the locking sleeve, allowing the ball joint seat to move. The locking sleeve engages with the second limiting part on the shaft through the second limiting groove, keeping the ball joint seat locked on the shaft.

[0042] The beneficial effects of this application are:

[0043] 1. When the filter needs cleaning, move the filter from the housing towards the cleaning chamber and clean it with the cleaning brush.

[0044] 2. Water is sprayed from the bottom up through the lower nozzle. The water flows through the filter screen and quickly separates the debris on the surface of the filter screen from the screen, making it easier for the cleaning brush to separate the debris from the filter screen.

[0045] 3. The movable plate facilitates the connection between the filter mechanism and the cleaning chamber, ensuring that water flowing off the filter screen can be collected by the cleaning chamber. Attached Figure Description

[0058] The second drive mechanism 300 is installed and connected to the filter mechanism 200 and is used to drive the filter mechanism 200 to move up and down and horizontally.

[0059] The cleaning mechanism 400 is located on one side of the housing 110 and is adapted to the filter mechanism 200.

[0060] The base 100 is provided with a support column 120, the second drive mechanism 300 is installed on the support column 120, and the cleaning mechanism 400 is installed on the support column 120. The cleaning mechanism 400 includes a cleaning chamber 410 and a cleaning brush 420.

[0061] The first drive mechanism is mounted on the base 100, and the housing 110 is movably mounted on the base 100. The first drive mechanism and the housing 110 are connected via a motor and gears. The first drive mechanism drives the housing 110 to rotate. The support column 120 is mounted on the base 100, and the second drive mechanism 300 is mounted on the support column 120. The second drive mechanism 300 is connected to the filter mechanism 200 via a lead screw, threaded seat, motor, and cylinder. The second drive mechanism 300 drives the filter mechanism 200 to move vertically and horizontally, thus controlling the filter mechanism 200. The filter mechanism 200 moves between the housing 110 and the cleaning mechanism 400. The filter mechanism 200 filters the slag through the filter screen 210. The filtration is carried out by a series of filter screens 210 with different mesh sizes. The cleaning mechanism 400 is installed on the support column 120 and placed on the side of the housing 110. When the filter mechanism 200 needs to be cleaned, it is moved from the housing 110 to the cleaning chamber 410. The filter mechanism 200 is cleaned by the cleaning brush 420. The slag and other debris are collected by the cleaning chamber 410 and then diverted to other collection equipment.

[0066] The first motor 441 is connected to the movable shaft 440;

[0067] The movable plate 450 is mounted on the cleaning chamber 410.

[0068] The lower nozzle 430 is installed in the cleaning chamber 410. Water is sprayed from the bottom up through the lower nozzle 430. The water flows through the filter screen 210, quickly separating the debris on the surface of the filter screen 210 from the filter screen 210, so that the cleaning brush 420 can easily separate the debris from the filter screen 210. The movable shaft 440 and the cleaning brush 420 are both installed and connected. The first motor 441 controls the rotation of the movable shaft 440, thereby controlling the rotation of the cleaning brush 420 around the movable shaft 440. This makes it easy to control the cleaning brush 420 to move away from or closer to the filter screen 210. The movable plate 450 facilitates the cooperation between the filtration mechanism 200 and the cleaning chamber 410, ensuring that the water flowing down the filter screen 210 can be collected by the cleaning chamber 410. The movable plate 450 is controlled by a cylinder.

[0069] Furthermore, the filtration mechanism 200 includes:

[0070] Shaft 220;

[0078] The abutment seat 460 is placed on the lower side of the cleaning chamber 410, and the drive seat 470 is hinged to the abutment seat 460, so that the shaft 220 moves into the rotating hole 451 and is placed above the abutment seat 460. Then it moves downward so that the first limiting part 472 on the drive seat 470 cooperates with the first limiting groove 221 of the shaft 220. The shaft 220 is driven to rotate by the second motor 471, so that the cleaning brush 420 can clean the filter screen 210.
