Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to an EPDM rubber crusher. Background Technology

[0002] Ethylene propylene diene monomer (EPDM) rubber is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene. It is a type of ethylene propylene rubber. Because its main chain is composed of chemically stable saturated hydrocarbons, with unsaturated double bonds only in the side chains, it exhibits excellent resistance to ozone, heat, and weathering. It also possesses very good elasticity at both high and low temperatures, can be processed into a very smooth surface, and has strong abrasion resistance, tear resistance, solvent resistance, and high-temperature resistance. It can be widely used in automotive parts, waterproof building materials, wire and cable sheathing, heat-resistant hoses, tapes, automotive seals, and other fields.

[0003] A search revealed that this utility model, authorized by Chinese Patent Publication No. CN 221789455 U, relates to an EPDM rubber crusher. It includes a base, a housing fixedly connected to the top of the base, a crushing chamber fixedly connected to the top of the housing, and a controller fixedly installed on the front of the housing. The housing has an external dust removal mechanism extending into its interior, and an external conveying mechanism extending into its interior as well. The dust removal mechanism includes a dust removal fan fixedly installed on the right side of the housing and an installation pipe fixedly installed inside the housing. A suction nozzle is fixedly connected to the side of the installation pipe away from the housing. A collection box is fixedly installed at the bottom of the dust removal fan, located on the right side of the housing. This EPDM rubber crusher, by activating the dust removal fan via the controller, draws dust generated during the EPDM rubber crushing process through the installation pipe and suction nozzle, facilitating the extraction of dust from the housing into the collection box. This protects the health of workers and achieves the advantage of convenient dust removal.

[0004] The rubber shredder described in the aforementioned patent still has some shortcomings. In order to better recycle EPDM rubber, it is often necessary to crush the recycled waste EPDM rubber. However, in actual use, the existing rubber shredder lacks a corresponding cooling mechanism. During the rubber shredding process, the blades are constantly rubbing against the rubber, which easily causes the blades to heat up. This results in some rubber sticking to the heated blades, which not only affects the shredding efficiency of the blades but also makes cleaning the stuck rubber troublesome, making it inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a EPDM rubber crusher, which solves the problem that existing rubber crushers lack a corresponding cooling mechanism during actual use. In the process of rubber crushing, the blades are constantly rubbing against the rubber, which easily causes the blades to heat up. This results in some rubber sticking to the heated blades, which not only affects the crushing efficiency of the blades but also makes cleaning the stuck rubber troublesome, making it inconvenient to use.

[0006] This utility model provides the following technical solution: an EPDM rubber crusher, including a crushing chamber, two transmission rods rotatably arranged inside the crushing chamber, a plurality of crushing blades evenly arranged on the transmission rods, the ends of the transmission rods being rotatably connected to the inner wall of the crushing chamber, two drive motors arranged on the outside of the crushing chamber, the drive shafts of the drive motors rotatably penetrating the inner wall of the crushing chamber and being fixedly connected to the ends of the transmission rods, a top closing cover rotatably arranged at the top of the crushing chamber, a blade cooling assembly arranged inside the crushing chamber, and a rubber collecting assembly arranged at the bottom of the crushing chamber;

[0007] The tool cooling assembly includes guide plates symmetrically arranged on both sides of the inner wall at the top of the crushing chamber. Each guide plate has a water inlet tank on its bottom side. Several water mist nozzles are evenly and obliquely arranged on the water inlet tank. A water supply pipe is provided on the outside of the crushing chamber. The end of the water supply pipe is connected to the water inlet tank through a connecting pipe. The end of the water supply pipe is provided with a pipe joint.

[0008] Preferred technical solution 1: The rubber collection assembly includes a waste liquid collection chamber disposed at the bottom of the crushing chamber, the top of the waste liquid collection chamber has a top opening, the bottom of the crushing chamber extends into the top opening, and two inner wall support plates are staggered on both sides of the inner wall of the waste liquid collection chamber, and a filter screen is disposed between the two inner wall support plates.

[0009] Preferred technical solution 2: The waste liquid collection chamber has a discharge port on its side, a discharge plate is provided on the outside of the discharge port, the other side of the waste liquid collection chamber is connected to a waste liquid discharge pipe, a valve is provided on the waste liquid discharge pipe, and support legs are evenly arranged around the bottom of the waste liquid collection chamber.

[0015] This solution enables a stable connection between the crushing chamber and the waste liquid collection chamber.

[0016] Compared with the prior art, this utility model provides a EPDM rubber crusher, which has the following beneficial effects:

[0017] (1) This utility model is provided with a blade cooling component on the crushing chamber and a rubber collection component at the bottom of the crushing chamber. The guide plate in the blade cooling component can protect the water mist nozzle and guide the rubber to fall between several crushing blades and be crushed. The water supply pipe can be connected to an external high-pressure water source and transported to the water mist nozzle through the connecting pipe. The water mist nozzle sprays the crushing blades that are heating up to cool them down, so as to prevent the crushing blades from overheating and causing some rubber to stick to the crushing blades, affecting the subsequent continuous crushing operation. At the same time, the sprayed water mist can also reduce the dust generated during the crushing process. The filter screen in the rubber collection component can filter the rubber particles containing moisture, so as to avoid the rubber containing too much moisture after crushing and making it difficult to handle.

[0025] Please see Figure 1-4 ,

[0026] Example 1: An EPDM rubber crusher includes a crushing chamber 1. Two transmission rods 2 are rotatably arranged inside the crushing chamber 1. Several crushing blades 3 are evenly arranged on the transmission rods 2. The ends of the transmission rods 2 are rotatably connected to the inner wall of the crushing chamber 1. Two drive motors 4 are arranged on the outside of the crushing chamber 1. The drive shafts of the drive motors 4 rotate through the inner wall of the crushing chamber 1 and are fixedly connected to the ends of the transmission rods 2. A top closing cover 5 is rotatably arranged at the top of the crushing chamber 1. A blade cooling assembly 6 is arranged inside the crushing chamber 1. A rubber collecting assembly 7 is arranged at the bottom of the crushing chamber 1.

[0027] The tool cooling assembly 6 includes guide plates 601 symmetrically arranged on both sides of the inner wall at the top of the crushing chamber 1. A water inlet tank 602 is provided on the bottom side of each guide plate 601. Several water mist nozzles 603 are evenly and obliquely arranged on the water inlet tank 602. A water supply pipe 604 is provided on the outside of the crushing chamber 1. The end of the water supply pipe 604 is connected to the water inlet tank 602 through a connecting pipe 605. A pipe joint 606 is provided at the end of the water supply pipe 604.

[0028] The rubber collection assembly 7 includes a waste liquid collection chamber 701 located at the bottom of the crushing chamber 1. The top of the waste liquid collection chamber 701 has a top opening 702, and the bottom of the crushing chamber 1 extends into the top opening 702. Two inner wall support plates 703 are staggered on both sides of the inner wall of the waste liquid collection chamber 701, and a filter screen 704 is provided between the two inner wall support plates 703. A discharge port 705 is provided on the side of the waste liquid collection chamber 701, and a discharge plate 706 is provided on the outside of the discharge port 705. A waste liquid discharge pipe 707 is connected to the other side of the waste liquid collection chamber 701, and a valve 708 is provided on the waste liquid discharge pipe 707. Support legs 709 are evenly arranged around the bottom of the waste liquid collection chamber 701.

[0029] Example 2: The difference between this example and Example 1 is that the guide plate 601 is inclined toward the inside of the crushing chamber 1, and the water mist nozzles 603 are all inclined.

[0030] This allows the guide plate 601 to play a certain role in guiding the material discharge, and the water mist nozzle 603 to drain water at an angle toward the two crushing blades 3.

[0031] Example 3: The difference between this example and Example 1 is that the filter screen 704 is inclinedly arranged in the waste liquid collection chamber 701, and the bottom end of the filter screen 704 extends to the side of the discharge port 705.

[0032] This allows the filter screen 704 to filter out moisture from the crushed rubber particles containing water, and the filtered rubber particles are discharged along the inclined surface of the filter screen 704.

[0033] Example 4: The difference between this example and Example 1 is that two fixed connecting plates 8 are symmetrically arranged at the bottom of both sides of the crushing chamber 1, and the fixed connecting plates 8 are fixedly connected to the top of the waste liquid collection chamber 701.

[0034] This ensures a stable connection between the crushing chamber 1 and the waste liquid collection chamber 701.

[0035] In this embodiment, because the existing rubber pulverizer lacks a corresponding cooling mechanism in actual use, and the blades are constantly rubbing against the rubber during the rubber pulverizing process, the blades can easily heat up due to friction, causing some rubber to stick to the heated blades. This not only affects the pulverizing efficiency of the blades, but also makes cleaning the stuck rubber troublesome, making it inconvenient to use.

[0036] In summary, in practical implementation, when users need to crush and recycle waste EPDM rubber, they first need to connect a water source to the pipe joint 606 and connect the drive motor 4 to electricity. The drive motor 4 is started and drives several crushing blades 3 to rotate in opposite directions through the transmission rod 2. The user puts the waste rubber into the top of the crushing chamber 1, and through the guidance of the guide plate 601, it falls between several crushing blades 3 for cutting and crushing.

[0037] While the shredder blade 3 is cutting the rubber, an external water source is supplied to the water supply pipe 604, and then to the water inlet tank 602 through the connecting pipe 605. The water is then sprayed onto the shredder blade 3 through several water mist nozzles 603 that are inclined at the bottom of the water inlet tank 602, thereby cooling down the shredder blade 3 which is heating up during shredding. This prevents the shredder blade 3 from overheating and causing some rubber to stick to the shredder blade 3, which would affect the subsequent continuous shredding operation.

[0038] Meanwhile, the water mist sprayed through the water mist nozzle 603 can also spray the dust generated during the crushing of waste rubber, thereby reducing dust and preventing the dust and rubber particles generated during the crushing process from being dispersed in the air, making the rubber crushing operation environment safer.

[0039] The crushed rubber falls from the bottom of the crushing chamber 1 into the waste liquid collection chamber 701. The waste liquid collection chamber 701 is equipped with a filter screen 704, which filters the falling crushed rubber particles, causing the rubber particles to move along the inclined surface of the filter screen 704 to the discharge port 705 for discharge. The water filtered by the filter screen 704 is trapped at the bottom of the waste liquid collection chamber 701 and can be discharged through the waste liquid discharge pipe 707 by opening the valve 708. The bottom of the waste liquid collection chamber 701 is inclined, which is more conducive to the discharge of wastewater.
