Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a dust-proof vibrating screen. Background Technique

[0002] Due to its good hardness and stable chemical properties, sand and gravel are often widely used as high-quality building materials and raw materials for concrete in fields such as houses, roads, highways, railways, and engineering. Now, a large amount of sand and gravel concrete is required in urban engineering construction, road construction and other construction projects. Different projects have different requirements for the particle size and uniformity of sand and gravel. Vibrating screens are selected and widely used for sand and gravel screening.

[0003] A dust-proof and noise-reducing vibrating screen disclosed in Chinese Patent with the publication number CN220072345U. Through the guide plate in the feed pipe, the material can move downward in a certain direction. When the vibrating screen is started, the vibration of the vibrating screen and the downward force generated by the material on the guide plate, through the action of the telescopic rod, make the guide plate move up and down in an arc shape, thereby vibrating the material. When the material falls downward, it passes through the water mist sprayed by the spray head of the transfer pump, which will wet the material and greatly reduce the dust generated in the subsequent process.

[0004] In view of the above related technologies, there are some deficiencies in this device. In actual use, although wetting the material by spraying water can achieve the effect of dust reduction, it also causes some problems. First of all, the quality and viscosity of the wetted material will increase, resulting in easy caking of the material. Such an increase in viscosity is not conducive to subsequent screening operations and greatly reduces the screening efficiency and quality. Due to the increase in the viscosity of the material, it may also cause blockage of the equipment and the screen mesh, further affecting the production efficiency and production quality. Therefore, it is necessary to provide a dust-proof vibrating screen to solve the above technical problems. Content of the Utility Model

One side of the top of the screening box 1 is fixedly inserted and installed with a feeding square pipe 8. A return-shaped dust suction box 12 is fixedly installed at the top of the feeding square pipe 8. A plurality of fixing rods 10 are fixedly installed on the outer surface of the feeding square pipe 8;

[0031] The feeding square pipe 8 is fixedly installed with a return pipe 7 through a fixing rod 10. An external connecting pipe 9 is fixedly installed on one side of the return pipe 7. A plurality of first connecting pipes 11 are fixedly connected between the return pipe 7 and the upper side of the outer surface of the return suction box 12. A first discharge port 15 is opened on one side of the screening box 1, and a second discharge port 18 is opened below the other side of the screening box 1. A first suction box 16 is fixedly inserted and installed above the first discharge port 15 on one side of the screening box 1;

[0032] A plurality of second connecting pipes 13 are fixedly connected between the first suction box 16 and the return pipe 7. A second suction box 19 is fixedly inserted and installed above the second discharge port 18 on the other side of the screening box 1. A plurality of third connecting pipes 20 are fixedly connected between the second suction box 19 and the return pipe 7.

[0033] A sound insulation frame 5 is fixedly installed at the bottom of the screening box 1, and the vibration motor 17 is located inside the sound insulation frame 5. A sound absorption cotton layer 22 is arranged on the inner surface of the sound insulation frame 5 to block and absorb the noise generated by the motor 17 during operation, reducing the transmission of noise to the outside.

[0034] In one embodiment, a plurality of support frames 14 are fixedly installed between the second connecting pipe 13 and the top of the screening box 1 to improve the stability of the second connecting pipe 13 during use.

[0035] In one preferred embodiment, the support frame 14 is composed of an annular sleeve and a connecting rod, and the annular sleeve and the connecting rod are fixedly connected. The annular sleeve is fixedly sleeved on the outer wall of the second connecting pipe 13, and the bottom end of the connecting rod is fixedly connected to the top of the screening box 1. The structure of the support frame 14 is simple and the manufacturing cost is low. While ensuring the structural firmness, the manufacturing and maintenance costs are reduced.

[0036] In one embodiment, a shock pad is fixedly installed at the bottom of the base 2 to effectively damp the whole device and reduce the overall noise of the device.

[0037] In one preferred embodiment, a box door 6 is arranged on the front of the screening box 1 to facilitate the cleaning and maintenance of the inside of the screening box 1.

[0038] The working principle of the present utility model is as follows: All electrical components appearing in this application are externally connected to a power supply and a control switch during use. When this device is in use, the external connection pipe 9 is connected to an external vacuum cleaner, and then the vibration motor 17 is started through the switch. Through cooperation with the connecting spring 4, the screening box 1 generates vibrations. The vibrations of the screening box 1 directly drive the vibrating screen 21 to vibrate. Then, the materials to be screened are added through the top opening of the loop-shaped dust suction box 12. The materials fall on the right-side area of the upper surface of the vibrating screen 21 under the guidance of the feeding square pipe 8. Due to the inclined installation of the vibrating screen 21 and the vibration effect of the vibrating screen 21, the materials will roll from the right side to the left side of the vibrating screen 21. During the rolling process, the vibrating screen 21 will screen the materials. Qualified materials will pass through the sieve holes on the vibrating screen 21 and fall to the bottom inside the screening box 1, and will finally be discharged through the second discharge port 18, while unqualified materials will be discharged through the first discharge port 15. During the material screening process, the vacuum cleaner is started. The vacuum cleaner generates a suction force. Through the passage formed by the external connection pipe 9, the loop-shaped pipe 7, the first connecting pipe 11, the second connecting pipe 13, and the third connecting pipe 20, suction forces are generated at the dust suction ports of the loop-shaped dust suction box 12, the first dust suction box 16, and the second dust suction box 19, so as to adsorb the dust generated at the feeding port and discharging port of the device, prevent the dust generated during the material screening process from floating into the surrounding environment and causing pollution, and ensure the health of the staff. This device adopts the method of negative pressure dust suction. Without affecting the physical properties of the screened materials, the dust reduction effect is remarkable and will not affect the quality and viscosity of the materials. This method ensures the screening efficiency and quality, improves the production efficiency and production quality, and has extremely high practicability and reliability.

[0039] When this device is in use, the vibration motor 17 serves as the driving source, and its own noise will be very large. Therefore, a sound insulation frame 5 is provided outside the vibration motor 17 to reduce the transmission of the noise generated by the vibration motor 17 to the outside world during operation. At the same time, through the setting of the sound-absorbing cotton layer 22, the noise generated by the vibration motor 17 is effectively absorbed. Through the intervention of the functions of sound insulation and sound absorption, the noise generated by the vibration motor 17 during operation is minimized from being transmitted to the outside world, the working environment is improved, the work efficiency is increased, and the potential impact of the noise on the staff is reduced.

For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
