Description

Technical Field

[0001] This utility model relates to the technical field of construction waste crushing equipment, and in particular to a novel dual-rotor structure crusher. Background Technology

[0002] In the field of construction waste treatment, crushing is the core link in realizing the resource recycling of construction waste. As a key piece of equipment, the performance of the crusher directly affects the processing efficiency, recycling quality and environmental protection level of construction waste.

[0003] The patent application CN222739291U describes a dual-rotor hammer crusher with a multi-stage crushing structure. However, the dust collection mechanism of this equipment uses a unidirectional suction design, resulting in poor airflow guidance and an inability to fully capture dust generated at the feed inlet, leading to a large amount of dust spreading into the working environment. Secondly, the filter screen is prone to clogging, and the equipment lacks an effective self-cleaning structure. Construction waste dust contains a large number of fine particles and sticky impurities, which easily adhere to the filter screen surface and clog the filter pores, increasing ventilation resistance and drastically reducing dust collection efficiency.

[0004] To address this, we designed a novel dual-rotor structure crusher. Utility Model Content

[0005] This utility model discloses a novel dual-rotor structure crusher, which aims to solve the technical problems of construction waste crushing equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel dual-rotor structure crusher includes a crusher body, and a dust removal mechanism is fixedly installed on the top of the crusher body, the position of which corresponds to the feed inlet of the crusher body. The dust removal mechanism includes a support plate fixedly connected to the left side of the crusher body. A collection box is fixedly installed on the upper surface of the support plate, as well as a dust suction hood and an air jet box fixed to the upper surface of the crusher body. Two air suction pumps are fixedly installed on the upper surface of the collection box. Several diversion air jet holes are opened on the surface of the air jet box. A filter screen is installed inside the collection box.

[0007] In a preferred embodiment, a rotating shaft is rotatably connected between the front and rear inner walls of the collection box. Two rotating cams are fixedly connected to the surface of the rotating shaft. The rotating cams are located below the filter screen and overlap with the lower surface of the filter screen.

[0008] In a preferred embodiment, rubber sealing strips are fixedly connected to all four edges of the filter screen, and the side of the rubber sealing strip away from the filter screen is fixedly connected to the inner wall of the collection box. A drain outlet is provided at the bottom of the collection box, and a sealing plate is installed on the outside of the drain outlet by bolts.

[0009] In a preferred embodiment, a drive box is fixedly disposed on the surface of the collection box, a drive motor is fixedly disposed inside the drive box, a drive gear is fixedly connected to the rotating shaft of the drive motor, one end of the rotating shaft extends into the interior of the drive box and is fixedly connected to a driven gear, and the drive gear meshes with the driven gear.

[0010] In a preferred embodiment, an air duct is fixedly provided on the upper surface of the collection box, the bottom output end of the air duct extends into the interior of the collection box, and the input end of the air duct extends into the interior of the dust collection hood, with the air outlet of the air duct located below the filter screen.

[0011] In a preferred embodiment, the air inlet of the air pump extends into the interior of the collection box, and the output of the air pump is fixedly connected to a delivery air pipe. A converging pipe is fixedly embedded on the back of the jet box, and the outputs of both delivery air pipes extend into the interior of the converging pipe.

[0012] In a preferred embodiment, the height of the jet box corresponds to the dust suction hood, and the jet box and dust suction hood are symmetrically distributed on the left and right sides above the feed inlet of the crusher body.

[0013] In a preferred embodiment, two strip baffles are fixedly connected to the top of the crusher body, and the two strip baffles are symmetrically distributed between the air jet box and the dust suction hood.

[0014] As can be seen from the above, the novel dual-rotor structure crusher provided by this utility model has the following technical effects.

[0015] Firstly, a dust removal mechanism is installed at the top feed inlet of the crusher, with the jet box and dust hood symmetrically distributed on both sides of the feed inlet. The jet box blows air through the diversion jet holes, and the dust hood sucks in the air to form a directional airflow, which comprehensively captures the dust generated at the feed inlet, thus achieving a highly efficient and thorough dust removal effect. At the same time, the suction pump provides strong suction, and the dust is quickly guided into the collection box through the air guide pipe to prevent the dust from spreading to the working environment. The strip baffle can guide the material to fall and at the same time help to gather the dust, improving the dust removal effect.

[0016] Secondly, by setting a rotating shaft inside the collection box, a drive motor can be used to drive a rotating cam to rotate. The cam continuously strikes the filter screen, realizing the self-vibration and dust removal of the filter screen, preventing dust from clogging the filter screen holes, and ensuring the continuous and stable operation of the dust removal system. The rubber sealing strip on the edge of the filter screen is tightly fitted to the inner wall of the collection box, and the filter screen can move up and down, preventing dust leakage and improving dust collection efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A novel dual-rotor structure crusher includes a crusher body 1, and a dust removal mechanism 2 is fixedly installed on the top of the crusher body 1. The position of the dust removal mechanism 2 corresponds to the feed inlet of the crusher body 1.

[0025] The dust removal mechanism 2 includes a support plate 201 fixedly connected to the left side of the crusher body 1. A collection box 202 is fixedly installed on the upper surface of the support plate 201, as well as a dust suction hood 203 and an air jet box 204 fixedly installed on the upper surface of the crusher body 1. The height of the air jet box 204 corresponds to that of the dust suction hood 203, and the air jet box 204 and the dust suction hood 203 are symmetrically distributed on the left and right sides above the feed inlet of the crusher body 1. Two strip baffles 214 are fixedly connected to the top of the crusher body 1, and the two strip baffles 214 are symmetrically distributed between the air jet box 204 and the dust suction hood 203.

[0026] It is worth noting that through the symmetrical layout of the jet box 204 and the dust hood 203, the converging effect of the strip baffle 214, and the strong suction provided by the suction pump 205, a directional airflow circulation is formed to comprehensively capture the dust generated at the feed inlet, effectively preventing dust diffusion and improving the cleanliness of the working environment.

[0027] Two suction pumps 205 are fixedly installed on the upper surface of the collection box 202, and several diversion jet holes 206 are opened on the surface of the jet box 204. A filter screen 207 is installed inside the collection box 202.

[0028] An air duct 211 is fixedly installed on the upper surface of the collection box 202. The bottom output end of the air duct 211 extends into the interior of the collection box 202, and the input end of the air duct 211 extends into the interior of the dust collection hood 203. The air outlet of the air duct 211 is located below the filter screen 207.

[0029] The air intake end of the suction pump 205 extends into the interior of the collection box 202, and the output end of the suction pump 205 is fixedly connected to the air delivery pipe 212. The back of the jet box 204 is fixedly embedded with a converging pipe 213, and the output ends of the two air delivery pipes 212 extend into the interior of the converging pipe 213.

[0030] A rotating shaft 208 is rotatably connected between the front and rear inner walls of the collection box 202. Two rotating cams 209 are fixedly connected to the surface of the rotating shaft 208. The rotating cams 209 are located below the filter screen plate 207 and overlap with the lower surface of the filter screen plate 207. Rubber sealing strips 210 are fixedly connected to all four edges of the filter screen plate 207.

[0031] It is worth noting that the drive motor 301 drives the rotating cam 209 to strike the filter screen 207, achieving self-vibration dust removal. Combined with the elastic design of the rubber sealing strip 210, it not only ensures the sealing performance of the filter, but also solves the problem of easy clogging of traditional filters, extends the service life of the filter, and ensures the continuous operation of the dust removal system.

[0032] A drive box 3 is fixedly installed on the surface of the collection box 202. A drive motor 301 is fixedly installed inside the drive box 3. A drive gear 302 is fixedly connected to the rotating shaft of the drive motor 301. One end of the rotating shaft 208 extends into the interior of the drive box 3 and is fixedly connected to a driven gear 303. The drive gear 302 meshes with the driven gear 303.

[0033] The side of the rubber sealing strip 210 away from the filter screen 207 is fixedly connected to the inner wall of the collection box 202. The bottom of the collection box 202 is provided with a drain port. A sealing plate 215 is installed on the outside of the drain port by bolts. The sealing plate 215 is fixed by bolts, which is easy to disassemble and facilitates dust cleaning. The connection of each structure is firm and the layout is reasonable. No complicated disassembly is required during later maintenance, which reduces the difficulty and cost of maintenance.

[0034] Working Principle: First, start the equipment. The drive motor 301 and two suction pumps 205 run synchronously. After the suction pumps 205 start, they quickly extract air from the collection box 202, creating a negative pressure inside the collection box 202. At the same time, the suction pumps 205 send the extracted air through the conveying air pipe 212 into the converging pipe 213. The converged airflow passes through the diversion air jet holes 206 on the surface of the jet box 204, forming a uniform directional airflow that blows towards the feed inlet. At this time, the operator puts the material to be crushed into the feed inlet from above. Under the guidance of the strip baffle 214, the material falls precisely into the crusher body 1 for crushing.

[0035] Dust generated during the crushing process flows towards the dust collection hood 203 under the propulsion of the airflow from the jet box 204. The dust collection hood 203, under the negative pressure of the collection box 202, generates strong suction, drawing in the dust-laden airflow. The dust-laden airflow is transported to the inside of the collection box 202 via the air duct 211, flowing upwards from below the filter screen 207. Dust is intercepted and filtered by the filter screen 207, while clean air flows upwards through the filter screen 207 and is drawn back in by the suction pump 205, entering the next airflow cycle. The intercepted dust settles to the bottom of the collection box 202 under gravity. When a certain amount of dust accumulates, the equipment is shut down, and the drain port is opened to treat the dust.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
