Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, and particularly relates to a dust hopper feeding flow assistance device for a dust collector. Background Art
[0002] The existing dust hopper feeding method of the dust collector is natural feeding through an inclined taper angle. When encountering materials with poor fluidity, a flow assistance device can be added to enable the materials to smoothly pass through the feeding port and enter the next process. Currently, the relatively common flow assistance devices are vibrators. By vibrating at a low frequency with a small motor, the dust hopper wall is knocked to loosen, flow, and descend the materials through the feeding port. The long-term operation of the vibrator motor will cause damage to the dust hopper wall, and even tear the welds of the dust collector body, resulting in material leakage, which will have an adverse impact on the surrounding environment and workers. Content of the Utility Model
[0003] Technical Objective: Aiming at the deficiencies existing in the above-mentioned existing dust hopper feeding of the dust collector, the utility model discloses a dust hopper feeding flow assistance device for a dust collector that can accelerate the feeding of the dust hopper, avoid material accumulation, and at the same time will not cause damage to the dust hopper structure.
[0004] Technical Solution: To achieve the above technical objective, the utility model adopts the following technical solutions:
[0005] A dust hopper feeding flow assistance device for a dust collector is arranged on the inner wall of the dust hopper, including an air inlet pipe arranged on the inner wall of the dust hopper. The end of the air inlet pipe is located inside the dust hopper, and the outside of the air inlet pipe is connected to a gas source. The gas source supplies gas to the air inlet pipe to separate the materials from the inner wall of the dust hopper and flow downward; a buffer structure for reducing the air flow velocity is arranged at the end of the air inlet pipe.
[0006] Preferably, the buffer structure of the utility model adopts an expanding horn-shaped structure, with the end having a smaller diameter connected to the air inlet pipe and the other end located inside the dust hopper.
[0007] Preferably, the air inlet pipes of the utility model are evenly distributed along the circumferential direction of the dust hopper, and an air ring for supplying gas to the air inlet pipes is arranged outside the dust hopper. The air ring connects the gas source and the air inlet pipes.
[0008] Preferably, a solenoid valve for controlling the on-off of the air flow is arranged at the inlet of the air ring of the utility model.
[0009] Preferably, an air source triple unit is arranged between the solenoid valve and the gas source of the utility model.
[0010] Preferably, a short connection interface is welded on the air ring of the utility model, and the air inlet pipe is threadedly connected to the short connection interface.
[0011] Beneficial Effects: The dust hopper feeding flow assistance device provided by the utility model has the following beneficial effects:
[0012] 1. The utility model uses an air inlet pipe arranged on the inner wall of the ash hopper to transport gas into the ash hopper, so that the material is separated from the ash hopper, enabling smooth discharging, avoiding the phenomenon of material accumulation, and at the same time not causing damage to the weld structure of the ash hopper, etc.
[0013] 2. A buffer structure is arranged at the end of the air inlet pipe of the utility model. Through the variable diameter structure of the buffer structure, the flow rate of the gas entering the ash hopper decreases after entering, which will not cause a large impact on the material, can evenly disperse the material, and will not generate dust.
[0014] 3. The air inlet pipes of the utility model are evenly distributed along the circumferential direction of the ash hopper and are supplied with gas through an air ring, which can supply gas to various positions of the ash hopper synchronously, and can simplify the gas supply structure and facilitate assembly.

Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. On the contrary, the following description provides a convenient illustration for implementing the exemplary embodiments of the present disclosure. In fact, those skilled in the art will clearly understand that various modifications and variations can be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure. For example, features described as part of one embodiment or example can be combined with another embodiment to produce yet another embodiment. It is intended that the present disclosure cover such modifications and variations that fall within the scope of the appended claims and their equivalents. Other objects, features, and aspects of the present disclosure are disclosed or will be apparent from the following detailed description. It is to be understood by those of ordinary skill in the art that this description is only for the description of exemplary embodiments and is not intended to limit the broader aspects of the present disclosure.
[0020] Such as Figure 1 and Figure 2The figure shows a dust hopper material flow assisting device disclosed by the present utility model, which is arranged at the inner wall of the dust hopper 1 and includes an air inlet pipe 2 arranged on the inner wall of the dust hopper. The end of the air inlet pipe 2 is located inside the dust hopper 1, and the outside of the air inlet pipe 2 is connected to a gas source. The gas source supplies gas to the air inlet pipe 2 to make the material separate from the inner wall of the dust hopper 1 and flow downward. A buffer structure 3 for reducing the air inlet flow rate is arranged at the end of the air inlet pipe 2.
[0021] The present utility model sets a buffer structure 3 to reduce the air inlet flow rate. While ensuring that the material can move down smoothly, it can avoid the generation of dust due to too fast air flow speed. To simplify the structure and facilitate installation and replacement, the buffer structure 3 of the present utility model adopts a gradually expanding horn-shaped structure. The end with a smaller diameter is connected to the air inlet pipe 2, and the other end is located inside the dust hopper 1. After the gas enters the buffer structure 3, due to the increase in the flow diameter, the corresponding flow rate will decrease.
[0022] The air inlet pipes 2 of the present utility model are evenly distributed along the circumferential direction of the dust hopper 1. An air ring 4 for supplying gas to the air inlet pipes 2 is arranged outside the dust hopper 1. A short connection interface 7 is welded on the air ring 4, and the air inlet pipe 2 is threadedly connected to the short connection interface 7, which is convenient for assembly, disassembly and replacement. The air ring 4 connects the gas source and the air inlet pipe 2, and a solenoid valve 5 for controlling the on-off of the gas flow is arranged at the inlet of the air ring 4.
[0023] A gas source triple unit 6 is arranged between the solenoid valve 5 and the gas source. The gas source triple unit 6 is an air filter, a pressure reducing valve and an oil mist separator in the intake air direction, which filters impurities in the supplied gas to ensure the cleanliness of the gas source. The control of the solenoid valve can be electrically controlled by a PLC to achieve automatic control, or it can be manually operated by a manual operation box according to the material flow situation on site.
[0024] When the dust hopper material flow assisting device of the present utility model is in use, the material flows downward along the dust hopper of the dust collector. When the solenoid valve is in the open state, the gas enters the air inlet pipe 2 through the air ring 4. When the gas enters the inside of the dust hopper 1 of the dust collector, it is in a diffused state after passing through the buffer structure. Multiple air flows can evenly disperse the material and at the same time expand the contact area. Due to the small air pressure, the material can be loosened and flow slowly, which can effectively solve the problems of material bridging and blockage; the gas source can be switched on and off at any time according to the material situation on site to facilitate the smooth discharge of the material; the material flow assisting device of the present invention is easy to operate, has no noise pollution, and can avoid damaging the welds of the bin wall of the dust hopper 1, and prolongs the service life of the equipment.
