Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology in plastics processing, chemical production and food processing, and in particular to a negative pressure feeding silo dust treatment system. Background Technology

[0002] Dust refers to solid particles suspended in the air. In our daily lives and work, dust is almost ubiquitous. Soil and rocks weather and break down into many tiny particles, which, along with pollen, spores, and other organic particles, drift in the air with the wind. In addition, much dust is a byproduct of industrial and transportation development; exhaust fumes from chimneys and internal combustion engines also contain large amounts of dust, generated from flour milling, quarrying, and other operations, as well as volcanic ash from eruptions. Dust in the atmosphere often contains many toxic components, harming human health. It easily penetrates the lungs, causing toxic pneumonia or silicosis, and sometimes even lung cancer. Furthermore, dust pollutes buildings, causing corrosion to valuable ancient structures. Dust settling on plant leaves hinders photosynthesis and inhibits their growth.

[0003] Industrial dust is a major threat to human health and a primary cause of various diseases. In existing plastics processing, chemical production, and food processing processes, dust treatment is costly, inefficient, and ineffective, resulting in dust spills, low material utilization, and difficulty in meeting current processing and environmental control requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a negative pressure feeding silo dust treatment system. In the existing production and processing technology, this system is convenient for controlling dust, avoiding dust overflow, reducing environmental pollution and material waste, and has high processing efficiency, ensuring a clean working environment and efficient utilization of materials.

[0005] To solve the above-mentioned technical problems, the solution of this utility model is as follows:

[0006] A negative pressure feeding hopper dust treatment system includes a feeding hopper with a sealed design. The top of the feeding hopper is connected to an inlet and a dust filtration unit, and the bottom is connected to an outlet. The dust filtration unit is connected to an exhaust unit, and a blower unit is provided at the bottom of the outlet. A detection unit is also provided on the feeding hopper. The exhaust unit, blower unit, and detection unit are connected to an integrated control unit via a signal transmission line.

[0007] The dust filtration unit includes a dust collection chamber and a negative pressure chamber isolated by a filter plate.

[0008] The filter plate includes a filter layer made of filter material and porous protective filter plates disposed on both sides of the filter layer.

[0009] The exhaust unit includes an exhaust fan connected to the dust collection bin and an exhaust pipe connected to the exhaust fan.

[0010] The blower unit includes an air inlet pipe disposed at the bottom end of the discharge port and a blower connected to the air inlet pipe.

[0011] The detection unit includes a dust concentration sensor and a monitor.

[0012] The feed inlet is sealed and connected to a feed pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] Due to the negative pressure, dust generated inside the feeding hopper is drawn into the dust filtration unit, where it accumulates. The gas is then discharged through an exhaust unit connected to the dust filtration unit, thus reducing dust pollution. After the material exits the discharge port, the generated dust is blown back into the feeding hopper by a blower unit, further reducing environmental pollution. The detection unit monitors the dust concentration inside the feeding hopper, and through the integrated control unit, adjusts the exhaust and intake volumes of the exhaust and blower units to effectively control overflowing dust. This effectively protects the environment, reduces material waste, and significantly improves dust handling efficiency. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1-6 As shown; a negative pressure feeding hopper dust treatment system includes a feeding hopper 1 with a sealed design. The top of the feeding hopper 1 is connected to an inlet 2 and a dust filter unit 3, and the bottom is connected to an outlet 4. The dust filter unit 3 is connected to an exhaust unit 5, and a blower unit 6 is provided at the bottom of the outlet 4. A detection unit 7 is also provided on the feeding hopper 1. The exhaust unit 5, the blower unit 6, and the detection unit 7 are connected to an integrated control unit through a signal transmission line.

[0023] In this application, when material enters through the feed inlet 2, the generated dust is drawn into the dust filter unit 3 due to the negative pressure. The dust accumulates inside the dust filter unit 3, and the gas is discharged through the exhaust unit 5 connected to the dust filter unit 3, thereby reducing dust pollution to the environment. After the material exits through the discharge outlet 4, the generated dust is blown back into the feeding hopper 1 through the blower unit 6, further reducing dust pollution to the environment. In this application, due to the setting of the detection unit 7, when a change in the dust concentration inside the feeding hopper 1 is detected, the exhaust volume and intake volume of the exhaust unit 5 and the blower unit 6 can be adjusted through the control of the integrated control unit, thereby achieving effective control of overflowing dust, protecting the environment, reducing material waste, and further improving dust treatment efficiency.

[0024] The dust filtration unit 3 includes a dust collection bin 8 and a negative pressure bin 10 separated by a filter plate 9. The dust collection bin 8 can collect dust, which can then fall back into the feeding bin 1 for material reuse, reducing material waste. The filter plate 9 can increase the filtration area, thereby improving dust treatment efficiency. The negative pressure bin 10 can increase the negative pressure space, which can facilitate the uniform and rapid exhaust of dust, improving the dust treatment effect and efficiency.

[0025] The filter plate 9 includes a filter layer 11 made of filter material and porous protective filter plates 12 disposed on both sides of the filter layer 11. The filter layer 11 can capture fine dust particles to ensure the cleanliness of the exhaust air. The porous protective filter plates 12 can protect the filter layer 11 and reduce the damage to the filter layer 11 caused by the generation of large particles.

[0026] The exhaust unit 5 includes an exhaust fan 13 connected to the dust collection bin 8 and an exhaust pipe 14 connected to the exhaust fan 13.

[0027] The blower unit 6 includes an air inlet pipe 15 located at the bottom of the discharge port 4, and a blower 16 connected to the air inlet pipe 15.

[0028] The detection unit 7 includes a dust concentration sensor and a monitor. This setup is primarily for facilitating the detection of dust concentration inside the feeding hopper 1, thereby enabling effective control of the dust concentration.

[0029] The feed inlet 2 is sealed and connected to the feed pipe 17.

[0030] During operation, due to the negative pressure, dust generated inside the feeding hopper 1 is drawn into the dust filter unit 3, where it accumulates. The gas is then discharged through the exhaust unit 5, which is connected to the dust filter unit 3, thus reducing dust pollution. After the material exits from the discharge port 4, the generated dust is blown back into the feeding hopper 1 through the blower unit 6, further reducing dust pollution. The detection unit 7 detects the dust concentration inside the feeding hopper 1, and through the control of the integrated control unit, adjusts the exhaust and intake volumes of the exhaust unit 5 and the blower unit 6 to effectively control overflowing dust. This effectively protects the environment, reduces material waste, and improves dust handling efficiency.

[0031] In this application, the integrated control unit, exhaust fan 13, blower 16, dust concentration sensor and monitor all adopt existing mature technologies.

[0032] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
