Description

Technical Field

[0001] This utility model relates to the field of proppant production technology, specifically to a dust suppression mechanism for a crusher used in proppant production. Background Technology

[0002] In hydraulic fracturing operations during oil and gas extraction, proppant supports the fracturing fractures, prevents fracture closure, and improves the flowability of oil or natural gas. Bauxite or quartz sand is the main raw material for proppant production. The crushing step in proppant production involves crushing large pieces of bauxite ore or quartz sand to a particle size suitable for subsequent grinding or screening. Jaw crushers or gyratory crushers are generally used to crush the proppant raw materials. The crushed material is then fed directly onto a conveyor belt via a chute connected to the crusher. However, when the crusher discharges the proppant raw material through the chute, there are problems as mentioned in the authorization announcement number CN 223197116 U "An anti-clogging and dust suppression device for a roller crusher", namely, the crushed material directly impacts the conveyor belt after being discharged from the chute, which can easily cause material spillage and dust, affecting the working environment and the health of construction personnel; and it can also easily cause premature damage to the conveyor belt. Utility Model Content

[0003] This invention addresses the problem of dust generation caused by direct impact when crushed materials are fed onto a conveyor belt. It provides a dust suppression mechanism for a crusher used in proppant production, which can buffer the material during feeding and reduce dust generation.

[0004] To solve the above problems, the technical solution of this utility model is: A dust suppression mechanism for a crusher used in proppant production includes a crusher with a conveyor belt rotatably mounted on its lower side. It also includes a feeding component, which comprises a connecting cylinder and a distribution assembly. The upper end of the connecting cylinder is connected to the discharge port of the crusher. The distribution assembly includes baffles and inclined plates. There are two baffles, arranged correspondingly front to back. Multiple inclined plates are spaced apart between the two baffles from left to right. The front and rear ends of each inclined plate are fixedly connected to two baffles. The lower end of each inclined plate is inclined to the right. The distance between the lower ends of every two adjacent inclined plates gradually increases from left to right. The upper ends of the two baffles and the upper ends of the left and right inclined plates together form a connecting hole, which is connected to the lower end of the connecting cylinder. The lower end of the distribution assembly is close to the upper side of the conveyor belt.

[0005] Furthermore, the connecting cylinder is equipped with a pulse dust collector, the input end of which is connected to the inside of the connecting cylinder and the output end is facing outward.

[0006] Furthermore, the distance between the upper ends of each pair of adjacent inclined plates is equal, the upper ends of the plurality of inclined plates are aligned, and the lower ends of the plurality of inclined plates are aligned.

[0007] Furthermore, there is a gap between the lower ends of the multiple inclined plates and the lower ends of the baffles. Except for the rightmost inclined plate, each inclined plate is connected to a guide plate at its lower end. The guide plate is an arc-shaped plate with an arc protrusion facing the lower left. The front and rear ends of each guide plate are fixedly connected to two baffles respectively, and the lower ends of the multiple guide plates are flush.

[0008] Furthermore, an elastic pad one is fixed to the right side of each of the guide plates, and an elastic pad two is fixed to the right side of the inclined plate connected to each guide plate.

[0009] Furthermore, each pair of adjacent inclined plates together with the front and rear baffles form a feeding channel.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: In this invention, after the material is crushed and fed into the crusher, the crushed material enters multiple feeding channels through the connecting cylinder. The feeding channels disperse the material and feed it to different positions on the conveyor belt, avoiding concentrated impact of the material on the conveyor belt, thereby reducing dust and damage to the conveyor belt. Moreover, the material in the feeding channels from left to right falls onto the conveyor belt sequentially, ensuring that the material falls at different times in different feeding channels, achieving layered accumulation and buffering between materials, thereby reducing dust.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-3As shown, a dust suppression mechanism for a crusher used in proppant production includes a crusher 1, a conveyor belt 2 rotatably mounted on the lower side of the crusher 1, and a feeding component connected to the discharge port of the crusher 1 for feeding material onto the conveyor belt 2. The feeding component includes a connecting cylinder 3 and a material distribution assembly. The connecting cylinder 3 is a rectangular cylinder with openings at both ends, and its upper end is connected to the discharge port of the crusher 1. The material distribution assembly includes baffles 4 and inclined plates 5. There are two baffles 4, which are arranged in a front-to-back manner. Multiple inclined plates 5 are spaced apart between the two baffles 4 from left to right. The inclined plates 5 are rectangular plates, and the front and rear ends of each inclined plate 5 are fixedly connected to two baffles 4 respectively. The lower end of each inclined plate 5 is inclined to the right. The distance between the lower ends of every two adjacent inclined plates 5 gradually increases from left to right. The upper ends of the two baffles 4 and the upper ends of the left and right inclined plates 5 together form a connecting hole. The connecting hole corresponds to the lower opening of the connecting cylinder 3 and is connected to the lower end of the connecting cylinder 3. The lower end of the material distribution assembly is close to the upper side of the conveyor belt 2.

[0014] The connecting cylinder 3 is equipped with a pulse dust collector 6, the input end of which is connected to the inside of the connecting cylinder 3 and the output end is facing outward.

[0015] The distance between the upper ends of each pair of adjacent inclined plates 5 is equal, the upper ends of the plurality of inclined plates 5 are aligned, and the lower ends of the plurality of inclined plates 5 are aligned.

[0016] There is a gap between the lower ends of the multiple inclined plates 5 and the lower ends of the baffles 4. Except for the rightmost inclined plate, each inclined plate 5 is connected to a guide plate 7 at its lower end. The guide plate 7 is an arc-shaped plate with an arc protrusion facing the lower left. Two baffles 4 are fixedly connected to the front and rear ends of each guide plate 7. The lower ends of the multiple guide plates 7 are flush. The purpose is to reduce the descent speed of the material after it passes through the guide plate 7. There is a gap between the lower end of the baffle of the material distribution component and the upper end of the conveyor belt 2.

[0017] Each of the guide plates 7 has an elastic pad 8 fixed on its right side, and each of the inclined plates 5 connected to the guide plate 7 has an elastic pad 9 fixed on its right side. Both the elastic pad 8 and the elastic pad 9 are sheet-like bodies made of elastic rubber.

[0018] Each pair of adjacent inclined plates 5 together with the front and rear baffles 4 form a feeding channel.

[0019] In use, the conveyor belt 2 rotates clockwise, and the crusher 1 crushes the dry bauxite or quartz sand material used to prepare the proppant. The material after being crushed by the crusher 1 is discharged through the connecting cylinder 3. The material in the connecting cylinder 3 enters each feeding channel through the lower end of the connecting cylinder 3. Multiple feeding channels can disperse the material and transport the material to different positions on the conveyor belt 2, avoiding the material from concentrating on impacting a single point and reducing the impact energy on the conveyor belt 2. Moreover, the elastic pad 1 8 and elastic pad 2 9 in each feeding channel can slow down the impact energy of the material, thereby reducing the generation of dust. The pulse dust collector 6 can suck away the dust generated by the collision and impact of the material on the elastic pad 1 8 and elastic pad 2 9. Furthermore, since the distance between the lower ends of every two adjacent inclined plates 5 gradually increases from left to right, the material moves for the shortest time in the leftmost feeding channel. After being guided by the guide plate 7, the material first moves to the right onto the conveyor belt 2. The material has a rightward speed, which can reduce the impact energy with the conveyor belt 2. The material is conveyed to the right by the conveyor belt 2 to form a material layer. The material falling from the second feeding channel from left to right lands on the material layer formed on the conveyor belt 2 in the left feeding channel, which can achieve material buffering and will not directly impact the conveyor belt 2. Similarly, the multiple feeding channels to the right successively discharge material onto the material layer discharged from the previous feeding channel. The material buffers itself, which can reduce the dust caused by the material impacting the conveyor belt 2, and further reduce the generation of dust.

[0020] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
