Abstract

This utility model relates to the field of phosphogypsum processing technology and discloses a crushing mechanism for a complete set of equipment for high-dosage modified phosphogypsum road construction materials. The mechanism includes a support frame, on which a crushing mechanism is fixedly mounted. A dust cover is provided on the crushing mechanism, and a dust-collecting filter structure is provided on the dust cover. The dust-collecting filter structure includes a dust-collecting cylinder fixedly mounted on the opposite side of the dust cover and connected to it. This crushing mechanism for high-dosage modified phosphogypsum road construction materials uses a motor to drive a rotating shaft, causing a cam to periodically press a rotating ring. This, through a sliding rod and connecting frame, drives a rectangular frame and a filter screen to reciprocate, causing the filter screen to vibrate and automatically clean itself.

Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum processing technology, specifically a crushing mechanism for a complete set of equipment for road construction materials with large dosage of modified phosphogypsum. Background Technology

[0002] Phosphogypsum solid waste is a type of solid waste generated by phosphate chemical enterprises during the production of products such as phosphoric acid using wet processes. Through specific processing techniques, phosphogypsum solid waste can be transformed into aggregates to replace natural aggregates as construction materials. The processing of recycled phosphogypsum aggregates involves dehydration, crushing, grinding, mixing, and granulation of raw materials such as phosphogypsum. Crushing is required during the crushing stage.

[0003] Announcement No. CN222872295U discloses a phosphogypsum recycled aggregate crusher. It addresses the shortcomings of existing crushing devices, which have open feed and discharge ports without any sealing or dust removal design. As a result, dust particles generated during crushing can spread to the outside through the feed and discharge ports, posing a significant hazard to human health and the working environment. The crusher improves upon these shortcomings by installing a flip-up cover to seal the feed port and by installing an exhaust fan and filter screen at the discharge port to filter the dust-containing air.

[0004] However, when the filter screen works in a high-concentration dust environment, the dust accumulation on the filter screen surface will form a dust layer, which not only requires frequent cleaning, but also increases the resistance of the filter screen as the dust accumulates, causing the fan to increase its power to maintain the air volume, resulting in increased energy consumption. Therefore, a crushing mechanism for a complete set of equipment for road construction materials with large dosage of modified phosphogypsum is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a crushing mechanism for a complete set of equipment for road construction materials with large dosage of modified phosphogypsum. It has the advantages of reducing dust accumulation and lowering cleaning frequency and maintenance costs. It solves the problem that when existing crushing devices filter dusty air through a filter screen, dust accumulates on the surface of the filter screen to form a dust layer, which not only requires frequent cleaning, but also increases the resistance of the filter screen as dust accumulates, requiring the fan to increase power to maintain airflow and leading to increased energy consumption.

[0006] To achieve the above-mentioned goals of reducing dust accumulation and lowering cleaning frequency and maintenance costs, this utility model provides the following technical solution: a crushing mechanism for a complete set of equipment for high-dosage modified phosphogypsum road construction materials, including a support frame, on which the crushing mechanism is fixedly installed, and on which the crushing mechanism is provided a dust cover, and on which the dust cover is provided a dust suction and filtration structure.

[0007] The dust collection and filtration structure includes a dust collection cylinder fixedly installed on the surface opposite to the dust cover and connected to the dust cover. A fan is fixedly installed at the end of the dust collection cylinder away from the dust cover. A rectangular frame is slidably installed inside the dust collection cylinder. A filter screen is fixedly installed inside the rectangular frame. A dust cleaning component for cleaning dust from the surface of the filter screen is provided between the dust collection cylinder and the rectangular frame.

[0008] Furthermore, the top feed inlet of the crushing mechanism is equipped with two dustproof covers, the bottom discharge outlet of the crushing mechanism extends into the dustproof cover, and one side of the dustproof cover has an open structure and is rotatably installed with a sealing door adapted to the opening.

[0009] Furthermore, two baffles are fixedly installed inside the dust cover, and a collection frame is snapped between the opposite surfaces of the two baffles. The bottom discharge port of the crushing mechanism is located directly above the collection frame.

[0010] Furthermore, the dust cleaning assembly includes a motor fixedly installed outside the vacuum cleaner cylinder, a rotating shaft extending into the inside of the vacuum cleaner cylinder fixedly installed at the output end of the motor, a cam fixedly installed on the surface of the rotating shaft, a connecting frame fixedly installed on the surface of the rectangular frame, a slide rod fixedly installed on the surface of the connecting frame, a dial ring fixedly installed on the surface of the slide rod, a top spring sleeved on the surface of the dial ring fixedly installed on the surface of the slide rod, a limit ring fixedly installed inside the vacuum cleaner cylinder, the slide rod passing through the limit ring, and a stop block fixedly installed at one end of the slide rod.

[0011] Furthermore, the cam is located above the dial ring, and the cam is in contact with the dial ring.

[0012] Furthermore, the filter screen is wavy in shape.

[0013] Furthermore, the surface of the vacuum cleaner is provided with a dust discharge port, and a dust collection box corresponding to the dust discharge port is magnetically attached to the surface of the vacuum cleaner.

[0014] Compared with the prior art, this utility model provides a crushing mechanism for a complete set of equipment for road construction materials with large dosage of modified phosphogypsum, which has the following beneficial effects:

[0015] The crushing mechanism of this complete set of equipment for high-dosage modified phosphogypsum road construction materials uses a motor to drive a rotating shaft, which causes a cam to periodically squeeze a chuck. This, in turn, drives a rectangular frame and a filter screen to reciprocate through a slide rod and connecting frame. This vibration of the filter screen enables automatic cleaning, preventing dust accumulation and the formation of a dust layer on the filter screen surface in high-concentration dust environments. This reduces the workload of frequent manual cleaning, effectively lowering maintenance costs and energy consumption, and improving the energy efficiency of the equipment. Furthermore, the wavy design of the filter screen increases the filtration area, allowing for more effective dust capture and improved filtration efficiency. During cleaning, the wavy structure also facilitates dust detachment, further enhancing the cleaning effect and ensuring the filter screen maintains excellent filtration performance at all times.

[0024] In this embodiment, the top feed inlet of the crushing mechanism 2 is provided with two dust cover plates 6, and the bottom discharge outlet of the crushing mechanism 2 extends into the dust cover 3. One side of the dust cover 3 has an open structure and is rotatably installed with a sealing door 7 that matches the opening, so that the crushing process is carried out in a relatively closed space, further preventing the leakage of dust and avoiding dust pollution to the surrounding environment.

[0025] In this embodiment, two baffles 8 are fixedly installed inside the dust cover 3. A collection frame 9 is snapped between the opposite surfaces of the two baffles 8. The bottom discharge port of the crushing mechanism 2 is located directly above the collection frame 9, which facilitates the collection of crushed materials and facilitates the transfer or further processing of the materials.

[0026] In this embodiment, the dust cleaning component 5 includes a motor 51 fixedly installed outside the vacuum cleaner 41. A rotating shaft 52 extending to the inside of the vacuum cleaner 41 is fixedly installed at the output end of the motor 51. A cam 53 is fixedly installed on the surface of the rotating shaft 52. A connecting frame 54 is fixedly installed on the surface of the rectangular frame 43. A slide rod 55 is fixedly installed on the surface of the connecting frame 54. A dial ring 56 is fixedly installed on the surface of the slide rod 55. A top spring 561 sleeved on the surface of the dial ring 56 is fixedly installed on the surface of the slide rod 55. A limiting ring 57 is fixedly installed inside the vacuum cleaner 41. The slide rod 55 passes through the limiting ring 57. A stop block 58 is fixedly installed at one end of the slide rod 55.

[0027] In this embodiment, the cam 53 is located above the dial ring 56, and the cam 53 is in contact with the dial ring 56.

[0028] In this embodiment, the filter screen 44 is wavy in shape.

[0029] In this embodiment, a dust discharge port 10 is provided on the surface of the dust collection cylinder 41, and a dust collection box 11 corresponding to the dust discharge port 10 is magnetically attached to the surface of the dust collection cylinder 41. The magnetically attached dust collection box 11 is easy to disassemble and install. When the dust collection box 11 is full of dust, it can be quickly removed for cleaning to prevent secondary pollution of the environment by dust.

[0030] The working principle of the above embodiments is as follows:

[0031] The modified phosphogypsum with a large amount of additive to be crushed is fed into the feed port at the top of the crushing mechanism 2. Two dust covers 6 are opened during feeding and closed after feeding is complete. The crushed material falls from the discharge port at the bottom of the crushing mechanism 2 into the collection frame 9 inside the dust cover 3. The sealing door 7 is closed during the crushing process. Under the action of the fan 42, the dust generated during the crushing process inside the dust cover 3 is sucked into the dust collection cylinder 41. When the dust-laden air passes through the filter screen 44, the dust is intercepted on the surface of the filter screen 44, while the purified air passes through... When the air is discharged through the fan 42 and the filter screen 44 needs cleaning, the motor 51 starts, and its output end drives the rotating shaft 52 to rotate. The cam 53 on the surface of the rotating shaft 52 rotates accordingly. When the cam 53 rotates, it periodically squeezes the ring 56. When the cam 53 squeezes the ring 56, the ring 56 drives the slide rod 55 and the rectangular frame 43 to move to one side, and the top spring 561 is compressed. When the cam 53 rotates through a certain angle and no longer squeezes the ring 56, the elasticity of the top spring 561 causes the ring 56, the slide rod 55 and the rectangular frame 43 to move in the opposite direction and return to their original positions. This process is repeated, and the rectangular frame 43 drives the filter screen 44 to reciprocate, causing the dust on the surface of the filter screen 44 to fall off. The dust falling off the surface of the filter screen 44 falls into the dust collection box 11 through the dust discharge port 10.
