Description

Technical Field

[0001] This utility model relates to the technical field of industrial dust collection equipment, and in particular to an industrial dust collection equipment with high efficiency and multi-stage filtration. Background Technology

[0002] Industrial dust mainly originates from the mechanical crushing and grinding of solid materials, the mixing, sieving, packaging and transportation of powdery materials, smoke and dust generated from the combustion of substances, and the oxidation and condensation of vapors produced when substances are heated in the air. Industrial dust seriously endangers human health. Toxic metallic dust and non-metallic dust (chromium, manganese, cadmium, lead, mercury, arsenic, etc.) can cause poisoning and even death when they enter the human body.

[0003] Equipment that separates industrial dust from flue gas is called an industrial dust collector or industrial dust removal equipment. The performance of a dust collector is expressed by the amount of gas it can handle, the resistance loss of gas passing through the collector, and its dust removal efficiency. At the same time, the price, operating and maintenance costs, service life, and ease of operation and management are also important factors to consider when evaluating its performance.

[0004] While the aforementioned technologies achieve the filtration of industrial dust, existing filter bag filtration equipment lacks an internal airflow guiding structure design in actual use. During operation, the airflow directly impacts the top of the filter bag, causing accelerated wear in this area and significantly shortening the filter bag's service life. Therefore, a high-efficiency multi-stage filtration industrial dust collection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an efficient multi-stage filtration industrial dust collection device, which aims to solve the problem that existing filter bag filtration devices lack a flow guiding structure, causing airflow to rush directly to the top of the bag, exacerbating wear and shortening service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency multi-stage filtration industrial dust collection device, comprising a tank, a support frame fixedly connected to the outer wall of the tank, a transparent plate fixedly connected to the outer wall of the tank, a cleaning assembly provided at the top of the tank, an inlet pipe fixedly connected to the top outer wall of the tank, a dust outlet fixedly connected to the bottom of the tank, an outlet pipe fixedly connected to the outer wall of the dust outlet, and a filtration assembly provided inside the tank;

[0007] The filter assembly includes a mounting base, a filter bag placed inside the mounting base, a flow guide plate fixedly connected inside the tank, and a filter plate fixedly connected inside the tank.

[0008] As a further description of the above technical solution:

[0009] The mounting base has a groove inside, and the outer wall of the filter bag is slidably connected to the inside of the groove.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the mounting base is rotatably connected to the inside of the tank. Multiple sets of filter bags are provided, and the multiple sets of filter bags are distributed in a ring along the center of the mounting base.

[0012] As a further description of the above technical solution:

[0013] The cleaning assembly includes a motor, the output shaft of which is fixedly connected to a screw, the outer wall of which is threaded with a threaded post, and a first brush is fixedly connected to the outer wall of the threaded post; a second brush is fixedly connected to the bottom of the first brush, and a ring is fixedly connected to the outer wall of the first brush.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the screw is fixedly connected to the inside of the mounting base, and the outer wall of the screw is rotatably connected to the inside of the tank.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the ring is slidably connected to the outer wall of the filter bag, and the outer wall of the ring is slidably connected to the inside of the tank.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the first brush is slidably connected to the outer wall of the filter bag.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the second brush is slidably connected to the outer wall of the filter bag.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting a guide plate, a filter bag, and a mounting base, the guide plate is fixed inside the tank, and the filter screen is set below the guide plate. This achieves the purpose of introducing a guide plate at the top of the filter bag, which can effectively guide the airflow entering the filter bag, make it evenly dispersed, and avoid excessive local airflow velocity, which would lead to severe local wear of the filter bag.

[0024] 2. In this utility model, by setting a motor, a first brush, and a second brush, the motor drives the threaded column to move on the screw, which in turn drives the first brush and the second brush to move and clean the surface of the filter bag. This achieves the timely removal of a large amount of accumulated dust on the surface of the filter bag, effectively restoring the air permeability of the filter bag, avoiding the decrease in filtration efficiency caused by dust accumulation, and thus significantly improving the filtration effect.

The outer wall of the mounting base 82 is rotatably connected to the inside of the tank body 1. The inside of the tank body 1 has a sliding groove to facilitate the rotation of the mounting base 82. Multiple sets of filter bags 83 are provided, and the multiple sets of filter bags 83 are distributed in a ring around the center of the mounting base 82. When it is necessary to improve the filtration effect, the guide plate 81 is fixed inside the tank body 1 and fixed to the upper end of the filter bag 83. The filter bag 83 is placed in the groove at the bottom of the rotating mounting base 82 inside the tank body 1. Industrial dust enters the tank body 1 from the inlet pipe 4 and exits from the outlet pipe 5 after passing through the guide plate 81 and the filter bag 83.

[0034] Reference Figure 1 , Figure 3 , Figure 4The cleaning component 7 includes a motor 76. The output shaft of the motor 76 is fixedly connected to a screw 71 with a smooth upper end and a threaded lower end. The motor 76 provides power to the screw 71 to make it rotate.

The filter bag 83 is placed in the groove at the bottom of the rotating mounting base 82 inside the tank 1. Industrial dust enters the tank 1 from the inlet pipe 4 and exits from the outlet pipe 5 after passing through the guide plate 81 and the filter bag 83. When it is necessary to clean the dust on the surface of the filter bag 83, the motor 76 is turned on to make the mounting base 82 rotate, which drives the filter bag 83 to rotate. At the same time, the threaded column 75 moves up and down on the outer wall of the screw 71, thereby driving the first brush 73, the second brush 74, and the ring 72 to move up and down on the outer wall of the filter bag 83 to clean the dust on the surface of the filter bag 83. The fallen dust falls from the filter plate 84 into the dust outlet 6 below.
