Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and more specifically, to a water-proof and drainage device for a hammer crusher. Background Technology

[0002] In the crushing stage of slag resource utilization, the hammer crusher has become a very balanced and ideal choice due to its powerful "combined crushing" capacity, controllable finished product particle size, efficient metal dissociation effect, good adaptability to complex materials, and low operating cost. It can efficiently and economically process waste slag with complex composition and different properties into recycled aggregate with uniform particle size that meets the standards for resource utilization, while maximizing the recovery of valuable metals, perfectly matching the core goal of resource utilization to "turn waste into treasure".

[0003] However, in actual operation, the material generates a large amount of fine particles and dust due to the impact of the high-speed rotating hammer. Usually, a spraying device is installed on the crusher for dust removal. Although the crushing is carried out in a closed cavity, long-term wear causes the gap between the two ends of the rotating shaft and the cavity to increase. Over time, the closed cavity will leak, and the water used for dust removal will flow out through the gaps and into the bearing, causing bearing damage and seriously affecting the service life of the crusher. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-proof and drainage device for a hammer crusher to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a crusher is included, a rotating shaft is provided on the crusher, a bearing seat is rotatably mounted on the rotating shaft via a bearing, and a shaft end sealing plate is provided between the crusher and the bearing seat;

[0006] The crusher is provided with a feed inlet at the top, and a box is provided at the top of the feed inlet. The box is provided with a nozzle for spraying water into the crusher.

[0007] A water-blocking disc is detachably installed between the bearing housing and the shaft end sealing plate to prevent water from flowing into the bearing housing. A drainage tray is installed at the bottom of the crusher to collect and discharge the water flowing out of the crusher.

[0008] In a preferred embodiment, the outer wall of the housing is provided with a water supply pipe, and the water supply pipe is provided with multiple branch pipes, the other end of which passes through the housing and is connected to the nozzle.

[0009] In a preferred embodiment, a ball valve is provided on the other side of the water supply pipe.

[0010] In a preferred embodiment, the drainage tray consists of two parts, an upper part and an lower part. The crusher is placed in the upper part, and the upper part of the drainage tray is provided with several guide grooves. The lower part of the drainage tray has a cavity structure, and the inner bottom wall of the lower part of the drainage tray is sloped. A drainage outlet is provided on the side with the lower slope.

[0011] In a preferred embodiment, the water-proof disc is provided with fastening bolts, and the water-proof disc is detachably connected to the bearing seat by the fastening bolts.

[0012] In a preferred embodiment, a sealing ring is provided between the water-proof disc and the rotating shaft.

[0013] The technical effects and advantages of this utility model are as follows: By setting a water-blocking disc, the water seeping out along the rotating shaft is effectively blocked, preventing it from entering the bearing seat and ensuring the long-term stable operation of the bearing. At the same time, the wastewater is collected and discharged in a centralized manner through the drainage tray, keeping the surrounding environment of the equipment dry and clean. This utility model has a simple structure, is easy to install and maintain, and significantly improves the service life of the hammer crusher under wet dust removal conditions.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1 To be continued Figure 4 The device shown is a water-proof and drainage device for a hammer crusher, including a crusher 1. Two bearing seats 102 are symmetrically arranged on the crusher 1, and a rotating shaft 103 is arranged between the two bearing seats 102. The rotating shaft 103 drives the crushing component, which consists of hammers (not shown in the figure) arranged on the outer wall of the rotating shaft 103. The crushing function of the crusher 1 can be realized by the rotation of the crushing component. A shaft end sealing plate 104 is sleeved on the rotating shaft 103 to improve the sealing of the crusher 1 cavity, so that the crushing of the material is carried out in a closed space.

[0022] To prevent the splashing of fine particles and dust generated during material crushing, a feed inlet 101 for feeding materials into the crusher 1 is provided at the top of the crusher 1. A housing 2 is provided at the top of the feed inlet 101, and a water supply pipe 3 is provided on the outer wall of the housing 2. Multiple branch pipes 4 are provided on the water supply pipe 3. The other end of each branch pipe 4 passes through the housing 2 and is provided with a nozzle 401 at the end. Water is supplied into the water supply pipe 3, so that the water flows to each branch pipe 4, and then the nozzle 401 sprays the water into the housing 2. While crushing the material, the fine particles and dust generated by the crushing of the material are affected by the water mist sprayed from the nozzle 401 and settle down, avoiding the injury to the operator caused by a large amount of fine particles and dust splashing.

[0023] To facilitate control of water input, a ball valve 5 is installed on one side of the water supply pipe 3. When water spraying is needed for dust suppression, simply open the ball valve 5 to allow water to flow to the nozzle. When water spraying is not needed or equipment maintenance is required, closing the ball valve 5 can completely cut off the water source. Compared to closing the main water source at a distance, directly closing the ball valve 5 is more convenient and faster.

[0024] As attached Figure 3 Appendix Figure 4 and attached Figure 5As shown, to prevent water from dripping outward from the shaft end gap into the bearing housing 102 when water sprays into the crusher 1 cavity, a water-blocking disc 7 is detachably installed between the bearing housing 102 and the shaft end sealing plate 104. The water-blocking disc 7 is detachably installed on the rotating shaft 103 by fastening bolts 701, and a sealing ring 702 is provided on the inner wall of the water-blocking disc 7. The sealing ring 702 is tightly attached to the outer wall of the rotating shaft 103. When water drips outward along the gap between the rotating shaft 103 and the shaft end sealing plate 104, the water will drip downward due to the obstruction of the water-blocking disc 7 and cannot enter the bearing housing 102, thereby effectively preventing water from entering the bearing housing 102 and avoiding damage to the bearing due to water ingress.

[0025] To collect water dripping and flowing from the crusher 1, a drainage tray 6 is installed at the bottom of the crusher 1. The drainage tray 6 is vertically arranged in two layers. The upper layer has multiple guide channels 602, and the lower layer is a cavity structure with a sloping inner bottom wall. A drain outlet 601 is provided on the lower side of the slope. The drainage tray 6 is U-shaped, with a through hole in the middle corresponding to the discharge port of the crusher 1. When the crusher 1 is in use, it needs to be placed on the drainage tray 6. When water drips onto the drainage tray 6, the water flows into the cavity of the drainage tray 6 through the guide channels 602. Since the inner bottom of the drainage tray 6 cavity is sloping, the water drips into the drainage tray 6 and then flow towards the drain outlet 601 to discharge the water. The design of the guide channels 602 separates the crusher 1 from the lower layer of the drainage tray 6, which can prevent the bottom of the crusher 1 from being submerged due to excessive water accumulation.
