Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment, specifically a gas disc guide dust hopper. Background Technology

[0002] A baghouse dust collector is a dry dust collection device suitable for capturing fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the dust hopper. Gas containing finer dust particles is purified by trapping the dust as it passes through the filter media. However, the dust hopper in existing baghouse dust collectors is prone to clogging at the bottom. Traditionally, nitrogen cannons are used for intermittent downward blowing, but this fixed direction creates dead zones, resulting in incomplete cleaning. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an air disc guide dust hopper, which solves the problem of fixed direction, dead corners, and incomplete dust cleaning.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust hopper with air discs, comprising a dust hopper, an air distribution manifold installed on the outside of the dust hopper, and air discs installed on the inner wall of the dust hopper. The dust hopper is conical in shape, with an external support installed on the outer wall of the dust hopper. The air distribution manifold is installed on the top of the external support, and a feed pipe is installed on the outer wall of the dust hopper. Multiple exhaust pipes are provided at the bottom of the air distribution manifold. Air discs are installed on each inner wall of the dust hopper, and the air discs are connected to the exhaust pipes via connecting hoses. Support legs are installed on the outer wall of the dust hopper, and the support legs are symmetrically distributed about the dust hopper.

[0005] Optionally, an air inlet pipe is installed at the center of the air distributor, a rotary valve is installed on the air inlet pipe, and a fixing strap is installed on the external bracket, which is fitted onto the outside of the air distributor.

[0006] Optionally, the air distribution manifold is equipped with a guide plate and a fixing plate. The guide plate is installed on both sides of the air distribution manifold, and the fixing plate is installed inside the lower part of the air distribution manifold. The fixing plate is arc-shaped and the edges are curved upward. The exhaust pipe is located below the fixing plate and is evenly distributed at the bottom of the air distribution manifold.

[0007] Optionally, a pressure sensor and a regulating valve are installed on the exhaust pipe. The pressure sensor is located below the regulating valve and is electrically connected to an external power source.

[0008] Optionally, there are two sets of air discs, with two discs in each set. The two sets of air discs are at different heights and are symmetrically distributed in each set.

[0009] This utility model provides a gas disc guide type dust hopper, which has the following beneficial effects: 1. This air disc guide dust hopper, by installing air discs on the inner wall of the dust hopper, can form an air film on the four inner walls of the dust hopper during use, preventing dust from falling into contact with the inner wall of the dust hopper, reducing friction, preventing dust accumulation, and improving the dust discharge effect of the dust hopper.

[0010] 2. This air disc guide-type dust hopper, by setting guide plates and fixing plates inside the air distribution manifold, can guide the airflow entering the air distribution manifold during use. It also improves the air pressure and air velocity of the airflow entering the exhaust pipe, making the air film formed by the air disc more stable and improving the quality of the air film. In addition, by setting air pressure sensors, the air intake pressure of each air disc can be monitored, further improving the quality of the air film. Attached Figure Description

[0012] 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.

[0013] Example 1 Please see Figures 1 to 3This utility model provides a technical solution for dust hoppers. Existing dust hoppers typically use nitrogen cannons for intermittent downward blowing during ash removal, resulting in blind spots. To avoid this, this application provides a disc-guided dust hopper, comprising a dust hopper 1, an air distribution manifold 4 installed on the outside of the dust hopper 1, and discs 7 installed on the inner wall of the dust hopper 1. The dust hopper 1 is conical, with an external support 3 installed on its outer wall. The air distribution manifold 4 is installed on top of the external support 3. A feed pipe 2 is installed on the outer wall of the dust hopper 1, and multiple exhaust pipes 10 are located at the bottom of the air distribution manifold 4. Discs 7 are installed on each inner wall of the dust hopper 1, and the discs 7 are connected to the exhaust pipes 10 via flexible hoses 12.

[0014] An air inlet pipe 5 is installed at the center of the air distributor 4. A rotary valve 6 is installed on the air inlet pipe 5. A fixing strap is installed on the external bracket 3 and is sleeved on the outside of the air distributor 4.

[0015] There are two sets of air discs 7, with two discs in each set. The two sets of air discs 7 are at different heights and are symmetrically distributed in each set.

[0016] Specifically, during soot blowing, the air inlet pipe 5 is connected to an external air pump, and air is drawn in through the external air pump. The air inlet pipe 5 guides the airflow into the air distribution manifold 4, and then the air distribution manifold 4 supplies air to the air disc 7. The air disc 7 is designed so that the airflow forms an air film on the outside of the air disc 7. Since the air film has almost no friction, the dust will slide off directly and will not stick to the inner wall of the dust hopper 1. Similarly, there will be no dead corners, which will cause the problem of dust accumulation.

[0017] Example 2 Please see Figure 4 The present invention provides a technical solution in which a guide plate 8 and a fixing plate 9 are provided inside the air distribution manifold 4. The guide plate 8 is installed on the two side end caps of the air distribution manifold 4, and the fixing plate 9 is installed inside the lower part of the air distribution manifold 4. The fixing plate 9 is arc-shaped and the edges are curved upward. The exhaust pipe 10 is located below the fixing plate 9 and is evenly distributed at the bottom of the air distribution manifold 4.

[0018] The exhaust pipe 10 is equipped with a pressure sensor 11 and a regulating valve. The pressure sensor 11 is located below the regulating valve and is electrically connected to an external power source.

[0019] Specifically, after the external airflow is introduced into the air distribution manifold 4 through the intake pipe 5, the airflow is blocked by the fixed plate 9 and moves along the surface of the fixed plate 9. Then, the airflow moves to the edge of the fixed plate 9 and is guided by the guide plate 8, entering below the fixed plate 9. Through the above process, the pressure and velocity of the airflow are relatively stable when it finally flows onto the exhaust pipe 10, without producing large fluctuations. This improves the stability of the air film formed by the air disc 7. Furthermore, through the setting of the air pressure sensor 11 and the regulating valve, the air pressure sensor 11 can detect the exhaust pressure in real time and transmit the signal to the remote terminal. The pressure can be adjusted in time, and the stability of the air pressure can be detected in time during use to prevent the air pressure from being too high or too low, which would affect the stability of the air film and thus affect the dust discharge capacity. This improves the convenience of using the dust hopper.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
