Description

Technical Field

[0001] This utility model relates to the field of sludge cloth technology, and in particular to a high-efficiency crushing device for sludge cloth. Background Technology

[0002] Vertical sludge deep pressure filter dewatering equipment is a type of mechanical dewatering equipment that has gradually emerged in recent years. Compared with common sludge dewatering machines, it has the advantages of simple system, larger single processing capacity, lower operating cost, and high-pressure mechanical vertical extrusion of sludge. Under the conditions of proper selection and dosage of equipment reagents and precise control, the moisture content of the influent sludge is about 80%, and the average moisture content of the outfluent sludge can reach 50%-55%. The sludge feeding mechanism is an important component of the vertical sludge deep pressure filter dewatering equipment. After the sludge comes out of the hopper, it is fed onto the filter belt through the feeding system.

[0003] In some existing sludge feeding systems, the prolonged residence time of sludge in the storage tank or conveying pipeline causes heavier particles to gradually settle and form larger clumps. These clumps can clog the screw gaps during the feeding process, resulting in alternating periods of material interruption and subsequent impact feeding, leading to uneven feeding. Furthermore, the large clumps can cause bulges between the two filter cloths during the subsequent filtration process, resulting in uneven stress on the filter cloths and reducing their service life. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of some existing sludge feeding systems. During the feeding process, the sludge stays in the storage tank or conveying pipeline for too long, which causes the heavier particles in the sludge to gradually settle and form large clumps. These clumps can block the screw gap during the feeding process, causing the feeder to alternate between instantaneous material interruption and subsequent impact feeding, resulting in uneven feeding. Furthermore, the large clumps can cause bulges between the two filter cloths during the subsequent filtration process, resulting in uneven stress on the filter cloths and reducing their service life. This invention provides a high-efficiency crushing device for sludge feeding.

[0005] The purpose of this utility model is achieved through the following technical solution: a high-efficiency crushing device for sludge cloth, including a crushing cylinder, a fixed shaft installed inside the crushing cylinder, multiple sets of fixed crushing rods installed on the fixed shaft, two sets of rotatable rotating rings installed on both sides of the crushing cylinder, multiple sets of scrapers installed between the two sets of rotating rings, and moving crushing rods with fixed crushing rods arranged alternately on the multiple sets of scrapers. The multiple sets of alternating fixed crushing rods and moving crushing rods can achieve mutual compression, thereby crushing the lumps in the feed sludge. At the same time, the fixed crushing rods and moving crushing rods themselves have a certain filtering function. During the rotation of the moving crushing rods, sludge of the appropriate size is quickly filtered, and the lumps of sludge are driven to rotate and be compressed quickly by the fixed crushing rods, improving the crushing efficiency of sludge lumps, thereby ensuring the uniformity of sludge material, avoiding uneven stress on the filter cloth caused by lumpy sludge and affecting the filter pressing effect, and extending the service life of the filter cloth.

[0006] A motor is installed on the crushing drum, and the power output end of the motor is connected to the rotating ring. The motor drives the rotating ring and the moving crushing rod to rotate.

[0007] A first screw conveyor is installed at the bottom of the crushing cylinder, and the bottom of the crushing cylinder is connected to the upper part of the first screw conveyor. A filter screen is installed between the crushing cylinder and the first screw conveyor. Two sets of symmetrical screw blades are installed inside the first screw conveyor. The discharge end of the first screw conveyor is located in the middle of the first screw conveyor. By setting two sets of symmetrical screw blades inside the first screw conveyor, the crushed sludge can be quickly concentrated and discharged, thereby ensuring the sludge conveying efficiency.

[0008] A further technical solution is to provide a sliding groove on the inner wall of the crushing drum away from the motor, and to slide the rotating ring in the sliding groove. This sliding connection between the sliding groove and the rotating ring ensures the stability of the rotating ring when it rotates inside the crushing drum.

[0009] A further technical solution is to open a limiting groove on the side of the crushing cylinder near the motor, and install a sealing ring on the rotating ring of the crushing cylinder near the motor that is slidably connected to the limiting groove. The rotating ring of the crushing cylinder near the motor is connected to the power output end of the motor. By setting the limiting groove and the sealing ring together, the sealing between the rotating ring and the side wall of the crushing cylinder can be guaranteed, and the leakage of sludge can be avoided to prevent external pollution.

[0010] A further technical solution is to have the scraper contact the inner wall of the crushing cylinder and the filter screen. By setting the scraper to contact the inner wall of the crushing cylinder, sludge can be prevented from sticking to the inner wall of the crushing cylinder and causing residue. Setting the scraper to contact the filter screen can clean the filter screen during rotation, preventing blocky sludge from clogging the filter screen and ensuring the feed efficiency of the filter screen.

[0011] A further technical solution is to install a second screw conveyor at the discharge end of the first screw conveyor. The discharge end of the second screw conveyor is connected to the distributor through a discharge pipe. By setting up the second screw conveyor, the discharge efficiency of the discharge end of the first screw conveyor can be improved, thereby ensuring the sludge supply to the distributor.

[0012] A further technical solution is to set the feed end of the crushing cylinder at the top of the crushing cylinder. By setting the feed end at the top of the crushing cylinder, the feed sludge can fully contact the fixed crushing rod and the moving crushing rod, thereby ensuring the crushing effect of the feed sludge.

[0013] A further technical solution is to install a multi-layer vibrating screen at the feed end of the crushing cylinder. The mud discharge end of the multi-layer vibrating screen is connected to the feed end of the crushing cylinder, and one side of the multi-layer vibrating screen is the impurity discharge end. The multi-layer vibrating screen can screen out impurities such as stones in the sludge, improve the purity of the sludge, and prevent stones from damaging the fixed crushing rod and the moving crushing rod. At the same time, the multi-layer vibrating screen can break up sludge clumps into smaller sludge clumps through rapid vibration, which can then be screened by the multi-layer vibrating screen and enter the crushing cylinder for further crushing.

[0014] This invention has the following advantages: Multiple sets of staggered fixed and moving crushing rods enable mutual compression, thereby breaking up clumps in the feed sludge. Simultaneously, the fixed and moving crushing rods themselves have a certain filtration function. During the rotation of the moving crushing rod, sludge of the appropriate size is quickly filtered, while the clumps of sludge rotate and are rapidly compressed by the fixed crushing rod, improving the crushing efficiency of the sludge clumps. This ensures the uniformity of the sludge material, preventing uneven stress on the filter cloth caused by clumps of sludge, which affects the filtration effect, and extending the service life of the filter cloth.

At the same time, the fixed crushing rods 3 and moving crushing rods 6 themselves have a certain filtration function. During the rotation of the moving crushing rods 6, sludge of the appropriate size is quickly filtered, and the lumps of sludge are driven to rotate and be compressed quickly with the fixed crushing rods 3, which improves the crushing efficiency of sludge lumps, thereby ensuring the uniformity of sludge material, avoiding uneven stress on the filter cloth caused by lumpy sludge, which affects the filtration effect, and extending the service life of the filter cloth.

[0026] A motor 15 is installed on the crushing cylinder 1. The power output end of the motor 15 is connected to the rotating ring 4. The motor 15 drives the rotating ring 4 and the moving crushing rod 6 to rotate.

[0027] A first screw conveyor 8 is installed at the bottom of the crushing cylinder 1. The bottom of the crushing cylinder 1 is connected to the upper part of the first screw conveyor 8. A filter screen 7 is installed between the crushing cylinder 1 and the first screw conveyor 8. Two sets of symmetrical screw blades 11 are installed inside the first screw conveyor 8. The discharge end of the first screw conveyor 8 is located in the middle of the first screw conveyor 8.

[0028] A groove 12 is provided on the inner side wall of the crushing cylinder 1 away from the motor 15. The rotating ring 4 is slidably connected to the groove 12. The groove 12 and the rotating ring 4 are slidably connected to ensure the stability of the rotating ring 4 when it rotates inside the crushing cylinder 1.

[0029] A limiting groove 13 is provided on the side of the crushing cylinder 1 near the motor 15. A sealing ring 14 that is slidably connected to the limiting groove 13 is installed on the rotating ring 4 on the side of the crushing cylinder 1 near the motor 15. The rotating ring 4 on the side of the crushing cylinder 1 near the motor 15 is connected to the power output end of the motor 15.

[0030] The scraper 5 is in contact with the inner wall of the crushing cylinder 1 and the filter screen 7.

[0034] The working process of this utility model is as follows: When using this device to crush sludge, the sludge in the sludge storage tank is first transported into the crushing cylinder 1 through a pipeline. The motor 15 drives the rotating ring 4 to rotate, so that the moving crushing rod 6 on the rotating ring 4 and the fixed crushing rod 3 in the crushing cylinder 1 alternately squeeze the feed sludge. Sludge that meets the size requirements is discharged through the filter screen 7, while the clumped sludge is crushed under the pressure of the moving crushing rod 6 and the fixed crushing rod 3 until it meets the requirements and is discharged. The two sets of spiral blades 11 in the first spiral conveyor 8 at the discharge end of the crushing cylinder 1 can quickly collect the sludge that meets the standards and discharge it. It is then transported to the cloth distributor by the second spiral conveyor 9 and distributed onto the filter cloth.
