Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge treatment crushing and extrusion device. Background Technology
[0002] Sludge crushing is a crucial step in the sludge treatment process. By crushing large pieces of sludge, the surface area of the crushed particles is increased, thereby accelerating the evaporation rate of sludge moisture and improving heat transfer efficiency. Furthermore, crushed sludge is easier to process in subsequent stages. Currently, existing technologies typically utilize two relatively rotating crushing rollers to compress and crush the sludge.
[0003] However, due to the stickiness of sludge, some sludge will adhere to the surface of the crushing roller during the crushing process. As the crushing continues, the amount of sludge adhering will gradually increase, which will reduce the crushing force of the crushing roller on the sludge and affect the crushing efficiency of the sludge. Utility Model Content
[0004] Therefore, it is necessary to provide a sludge treatment compression crushing device to address the problem that the sludge adhering to the surface of the crushing roller gradually increases during the continuous crushing process, which leads to a decrease in the crushing force of the crushing roller on the sludge and affects the sludge crushing efficiency.
[0005] The device includes: a mounting frame, on the top of which is mounted a crushing box; two rotating rollers are rotatably connected to the inner wall of the crushing box; multiple sets of evenly distributed crushed blocks are fixedly connected to the surface of the rotating rollers; and a cleaning mechanism, which includes a drive assembly disposed on one side of the crushing box, fixed rods fixedly connected to both sides of the inner wall of the crushing box, and fixed plates fixedly connected to the ends of the fixed rods away from the inner wall of the crushing box. The opposite sides of the two fixed plates are in contact with the surfaces of the two rotating rollers, and multiple evenly distributed cleaning grooves are formed on one side of the fixed plates. The number and position of the cleaning grooves correspond one-to-one with the number and position of the multiple sets of crushed blocks.
[0006] In one embodiment, the cleaning mechanism includes two mounting rods that are slidably connected to the inner wall of the crushing chamber. Multiple evenly distributed cleaning rods are fixedly connected to the opposite sides of the two mounting rods. The top end of the cleaning rod is attached to the bottom end of the fixed plate, and the cleaning rod is disposed between two adjacent cleaning slots.
[0007] In one embodiment, the drive assembly includes a mounting plate fixedly connected to the surface of the crushing chamber. A first motor is mounted on one side of the mounting plate, and the output shaft of the first motor passes through the mounting plate and is fixedly connected to a reciprocating screw. A moving rod is provided on the surface of the reciprocating screw, and one end of two mounting rods passes through the crushing chamber and is fixedly connected to one side of the moving rod. This facilitates driving the mounting rods to move the corresponding multiple cleaning rods reciprocally in the horizontal direction.
[0008] In one embodiment, a limiting rod is fixedly connected to one side of the fixing rod, and a limiting groove is formed on the surface of the mounting rod. The surface of the limiting rod is slidably connected to the inner wall of the limiting groove. This helps to limit the movement distance of the cleaning rod and avoid the cleaning rod from interfering with the rotating broken pieces during reciprocating movement.
[0009] In one embodiment, the other end of the fixing plate has multiple evenly distributed through grooves. The inner walls of the through grooves are inclined, and the opening at the top of the through groove is smaller than the opening at the bottom. This facilitates better drainage of soil above the fixing plate and prevents sludge from accumulating on the fixing plate and re-adhering to the surface of the rotating roller.
[0010] In one embodiment, the vertical cross-section of the fixing plate is a right-angled triangle, with the lower end of the fixing plate farther from the rotating roller. This facilitates better sliding of sludge falling onto the fixing plate.
[0011] In one embodiment, the vertical cross-section of the cleaning rod is an isosceles triangle. This facilitates better removal of the sludge scraped off by the cleaning rod.
[0012] In one embodiment, two guide plates are fixedly connected to the inner top wall of the crushing chamber, and the guide plates are inclined. This facilitates the guidance of sludge during the sludge feeding process, allowing the sludge to fall more effectively into the crushing area. Beneficial effects
[0013] 1. In this solution, during the process of two rotating rollers driving multiple sets of crushing blocks to squeeze and crush sludge, the fixed plate and multiple cleaning grooves in the cleaning mechanism will simultaneously scrape off the sludge attached to the surface of the rotating rollers and the sides of the crushing blocks, keeping the surface of the rotating rollers clean and keeping the crushing blocks clean when they rotate to crush the sludge again. This avoids sludge adhering to and accumulating on the surface of the rotating rollers and crushing blocks, ensuring the crushing efficiency of the crushing blocks on the sludge. The reciprocating movement of multiple cleaning rods between two adjacent cleaning grooves is beneficial for scraping off the sludge cleaned at the bottom of the fixed plate, which helps to ensure the cleaning effect of the fixed plate and multiple cleaning grooves on the surface of the rotating rollers and the sides of the crushing blocks.
[0014] 2. The inclined surface at the top of the fixed plate and the multiple through grooves help the soil above the fixed plate to fall off better, preventing the sludge from accumulating on the fixed plate and re-adhering to the surface of the rotating roller. Attached Figure Description

[0028] The following is combined with Figures 1-5 This invention describes a sludge treatment crushing and extrusion device.
[0029] In one embodiment, a sludge treatment crushing and extrusion device includes: a mounting frame 100, a crushing box 200 mounted on the top of the mounting frame 100, two rotating rollers 300 rotatably connected to the inner wall of the crushing box 200, and multiple sets of uniformly distributed crushed blocks 400 fixedly connected to the surface of the rotating rollers 300.
[0030] The cleaning mechanism 500 includes a drive assembly 510 disposed on one side of the crushing box 200. Fixed rods 520 are fixedly connected to both sides of the inner wall of the crushing box 200. Fixed plates 530 are fixedly connected to the ends of the fixed rods 520 away from the inner wall of the crushing box 200. The opposite sides of the two fixed plates 530 are in contact with the surfaces of the two rotating rollers 300 respectively. Multiple evenly distributed cleaning grooves 531 are opened on one side of the fixed plates 530. The number and position of the cleaning grooves 531 correspond one-to-one with the number and position of the multiple sets of crushed blocks 400.
[0031] In this embodiment, each set of crushed blocks 400 includes multiple crushed blocks 400 arranged in a ring. A feed frame is provided at the top of the crushing box 200, and a discharge port is provided at the bottom of the crushing box 200. Multiple sets of crushed blocks 400 are staggered on the surfaces of the two rotating rollers 300. Multiple cleaning grooves 531 opened on the two fixed plates 530 correspond one-to-one with multiple crushed blocks 400 on the surfaces of adjacent rotating rollers 300. The rotation path of each set of crushed blocks 400 coincides with the corresponding cleaning groove 531. The center point of the fixed plate 530 is on the same horizontal plane as the rotating roller 300. Therefore, the crushed block 400 will pass through the cleaning groove 531 during rotation. When the crushed block 400 passes through the cleaning groove 531, both sides of the crushed block 400 are in contact with the inner wall of the cleaning groove 531, and the end of the crushed block 400 away from the rotating roller 300 does not affect the inner wall of the cleaning groove 531 during rotation.
[0032] It should be noted that one end of each of the two rotating rollers 300 extends through the crushing box 200 and is fixedly connected to a gear. The two gears mesh together. A second motor is fixedly connected to the top of the mounting bracket 100. One end of one of the gears, away from the rotating roller 300, is fixedly connected to the output shaft of the second motor. The controller starts the second motor, driving one of the gears to rotate clockwise, which in turn drives the other two gears to rotate counterclockwise. This, in turn, drives the two rotating rollers 300 to rotate the corresponding sets of crushed blocks 400 in opposite directions. (See reference...) Figure 2 .
[0033] like Figure 5 As shown, the cleaning mechanism 500 includes two mounting rods 540 that are slidably connected to the inner wall of the crushing box 200. Multiple evenly distributed cleaning rods 550 are fixedly connected to opposite sides of each mounting rod 540. The top end of each cleaning rod 550 is attached to the bottom end of a fixed plate 530, and the cleaning rods 550 are positioned between two adjacent cleaning slots 531. The vertical cross-section of each cleaning rod 550 is an isosceles triangle.
[0034] In this embodiment, when the device is in its initial state, one side of the cleaning rod 550 is on the same vertical plane as the inner wall of an adjacent cleaning groove 531. The maximum horizontal distance that the cleaning rod 550 can move is the distance between two adjacent cleaning grooves 531. When the device is running, the drive mounting rod 540 drives the corresponding multiple cleaning rods 550 to move towards the first motor 512. When the other side of the cleaning rod 550 is on the same vertical plane as the inner wall of another adjacent cleaning groove 531, the drive assembly 510 drives the cleaning rod 550 to move away from the first motor 512.
[0035] like Figure 3 and Figure 4 As shown, the drive assembly 510 includes a mounting plate 511 fixedly connected to the surface of the crushing box 200. A first motor 512 is mounted on one side of the mounting plate 511. The output shaft of the first motor 512 passes through the mounting plate 511 and is fixedly connected to a reciprocating screw 513. A moving rod 514 is provided on the surface of the reciprocating screw 513. One end of two mounting rods 540 passes through the crushing box 200 and is fixedly connected to one side of the moving rod 514.
[0036] In this embodiment, corrugated sleeves are fixedly connected to both sides of the moving rod 514, and the reciprocating screw 513 is disposed inside the corrugated sleeves. One end of the corrugated sleeve away from the moving rod 514 is fixedly connected to the surface of the mounting plate 511, and the other end of the corrugated sleeve away from the moving rod 514 is fixedly connected to one side of the crushing box 200. The corrugated sleeves are rubber components, and the reciprocating screw 513 is disposed inside the corrugated sleeves. The corrugated sleeves protect the reciprocating screw 513 and ensure that the connection between the reciprocating screw 513 and the moving rod 514 is stable.
[0037] like Figure 5 As shown, a limiting rod 570 is fixedly connected to one side of the fixing rod 520, and a limiting groove 560 is formed on the surface of the mounting rod 540. The surface of the limiting rod 570 is slidably connected to the inner wall of the limiting groove 560.
[0038] In this embodiment, when the drive mounting rod 540 moves toward the first motor 512, the limiting rod 570 slides within the limiting groove 560. The maximum movement path of the limiting rod 570 within the limiting groove 560 is the distance between two adjacent cleaning grooves 531.
[0039] like Figure 5 As shown, the other end of the fixing plate 530 has a plurality of evenly distributed through grooves 532. The inner wall of the through grooves 532 is inclined, and the top opening of the through groove 532 is smaller than the bottom opening. The plurality of through grooves 532 are respectively opened between two adjacent cleaning grooves 531.
[0040] like Figure 3As shown, the vertical cross-section of the fixing plate 530 is a right-angled triangle, and the lower end of the fixing plate 530 is farther away from the rotating roller 300. The top end of the fixing plate 530 is inclined.
[0041] like Figure 2 As shown, two guide plates 110 are fixedly connected to the inner top wall of the crushing box 200, and the guide plates 110 are inclined. The two guide plates 110 form an inverted "V" shape, and the openings formed at the lower ends of the two guide plates 110 are located above the crushing area of the multiple sets of crushed blocks 400.
[0042] Working principle: The sludge to be crushed is placed into the crushing box 200 through the feed frame. Guided by two guide plates 110, the sludge falls into the crushing area. Simultaneously, two rotating rollers 300 drive multiple sets of crushing blocks 400 to rotate in opposite directions. This causes the crushing blocks 400, which are staggered on the two rotating rollers 300, to crush the sludge. The crushed sludge is discharged through the discharge port. During the crushing process, when one rotating roller 300 rotates clockwise past one of the fixed plates 530, the bottom of the fixed plate 530 scrapes off the sludge adhering to the surface of the rotating roller 300. When the other rotating roller 300 rotates counterclockwise past the other fixed plate 530, the bottom of the fixed plate 530 scrapes off the sludge adhering to the surface of the rotating roller 300. The sludge adhering to the surface of the plate is scraped off, and multiple sets of crushing blocks 400 continuously penetrate the corresponding cleaning grooves 531 during the rotation and crushing process. During the process of the crushing blocks 400 penetrating the cleaning grooves 531, the bottom of the cleaning grooves 531 scrapes off the sludge adhering to both sides of the crushing blocks 400. During this process, the controller starts the first motor 512 to drive the reciprocating screw 513 to rotate, thereby driving the moving rod 514 to drive the two mounting rods 540 to reciprocate in the horizontal direction. This causes the two mounting rods 540 to drive the corresponding multiple cleaning rods 550 to reciprocate between two adjacent cleaning grooves 531. During the movement, the mud at the bottom of the fixed plate 530 is scraped off, thereby ensuring the cleaning effect of the fixed plate 530 and the multiple cleaning grooves 531.
[0043] Note: The reciprocating screw 513 is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 513 causes the side of the helical groove to push the slider placed in the helical groove to make axial reciprocating motion. Therefore, when the reciprocating screw 513 rotates, it will drive the moving rod 514 to reciprocate in the horizontal direction.
[0044] It should be noted that the motors and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. The motor can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.
[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
