[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a compressed air blowing device for preventing material from arching. Figure 1-Figure 4 As shown, it includes an annular tube 1, and a plurality of blowing components 2 are installed at the lower part of the annular tube 1 near the outer wall of the discharge end 4, which are used to blow gas into the inner side of the discharge end 4. The outer wall of one side of the annular tube 1 is connected with an air connecting pipe 3. The blowing component 2 includes a branch pipe 21, and a pressure pulse valve 22 is installed at the bottom end of the branch pipe 21. The outer side of the pressure pulse valve 22 is connected with a plurality of gas distribution pipes 23, and the outer end of the gas distribution pipe 23 is connected to the inside of the discharge end 4. The pressure pulse valve 22 refers to a diaphragm valve that is controlled by a pilot valve such as an electromagnetic or pneumatic valve and can instantly open and close a high-pressure gas source to generate pulses. The design of the pressure pulse valve 22 enables the compressed air to be sprayed into the material evenly and forcefully in the form of pulses, thereby ensuring the optimization of the blowing effect, thereby more effectively solving the problem of material arching.

[0023] In this embodiment, a valve 31 is installed on the air connection pipe 3 to facilitate the opening and closing operation of the air connection pipe 3.

[0024] Specifically, a plurality of air outlets 11 are provided at the bottom of the annular tube 1. The number of the air outlets 11 is four and they are arranged in a circular shape with equal intervals. The air outlets 11 are connected to the upper end of the branch pipe 21. An air inlet 12 is provided on one side of the annular tube 1. The air inlet 12 is connected to one end of the air receiving pipe 3, so that air can enter the interior from all directions of the discharge end 4.

[0025] Furthermore, a valve air inlet end 221 is provided at one end of the pressure pulse valve 22, and the valve air inlet end 221 is connected to the bottom end of the branch pipe 21, so that the air can be sprayed into the material evenly and forcefully in the form of pulses.

[0026] Furthermore, the gas distribution pipe 23 is an L-shaped structure as a whole, including a front section 231 and a rear section 232. One end of the front section 231 is connected to the gas outlet end of the pressure pulse valve 22, and one end of the rear section 232 is connected to the discharge end 4. A dustproof net 233 is installed at the connection, which has a good dustproof effect.

[0027] Furthermore, the inner side of the annular tube 1 is welded and fixed to the outer wall of the discharge end 4 to ensure the positioning of the annular tube 1 .

[0028] Furthermore, there are four gas distribution pipes 23 , which are arranged in a circular manner with equal spacing outside the pressure pulse valve 22 , so that the gas is evenly introduced into the discharge end 4 , ensuring uniform blowing operation on the materials at various locations.

[0029] Furthermore, the annular tube 1, the air blowing assembly 2, and the air connecting tube 3 are all made of stainless steel tubes, which will not be damaged or rusted after long-term use.

[0030] When the compressed air blowing device for preventing material arching of the utility model is used, the compressed air first enters the annular tube 1 through the air connection pipe 3, and the valve 31 installed on the air connection pipe 3 is used to control the on and off of the air flow. When blowing is required, the valve 31 is opened, and the compressed air enters the annular tube 1 through the air inlet 12. The four air outlets 11 arranged at the bottom of the annular tube 1 are arranged in a circular shape with equal spacing, ensuring that the compressed air can be evenly distributed to each blowing component 2. Each blowing component 2 is connected to the air outlet 11 through a branch pipe 21.

[0031] When the compressed air flows through the branch pipe 21, it reaches the pressure pulse valve 22 installed at the bottom of the branch pipe 21. The pressure pulse valve 22 is a diaphragm valve that can instantly open and close the high-pressure air source to generate pulses. Under the action of the control signal, the pressure pulse valve 22 will open and close rapidly, thereby ejecting the compressed air in the form of pulses. These pulsed compressed air then enters the discharge end 4 through the air distribution pipe 23. The air distribution pipe 23 is designed as an L-shaped structure to ensure that the airflow can smoothly change direction and spray into the discharge end 4. A dustproof net 233 is also installed at the connection between the air distribution pipe 23 and the discharge end 4 to prevent materials from entering the air distribution pipe 23 and causing blockage.

[0032] In this way, compressed air is injected into the material evenly and forcefully in the form of pulses, effectively destroying the material arch and restoring the normal flow of the material. The whole process is highly automated and easy to operate, which can significantly improve production efficiency and reduce equipment failure rate.

[0033] Finally, it should be noted that the electronic components in the pressure pulse valve 22 in this embodiment are all universal standard parts or parts known to technical personnel in this field. Their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
