Description

Technical Field

[0001] This utility model relates to the technical field of dust collector bag cleaning, and in particular to a multifunctional pneumatically controlled dust collector bag cleaning and inflation cannon. Background Technology

[0002] Because environmental protection equipment exhibits many drawbacks under different working conditions, especially bag filters in dust control equipment, bag filters have a high market share and are applicable to complex working conditions. In particular, when dealing with highly viscous dust or when the bag filter itself has poor pulse backflushing effect, the bag filter may experience system paralysis due to bag sticking, leading to an environmental crisis for the enterprise. Therefore, it is necessary to use a dust removal device to clean it.

[0003] Existing dust removal devices include the dust collector bag cleaning air cannon disclosed in the utility model patent with announcement number CN221815567U. This device uses a mobile rechargeable power supply to control the electromagnetic pulse valve, thereby achieving dust removal of the dust collector bag through air pressure. In addition to the above, there are also plug-in air cannons, which are operated by connecting to a 220-volt power supply.

[0004] However, during use, it was found that the aforementioned dust removal devices, which are electrically driven, are costly and have batteries, making transportation requirements quite strict, especially for sea transport in foreign trade, which increases transportation costs. The plug-in inflatable cannons, on the other hand, require a power source, posing a greater risk and needing a nearby power source, affecting usability. Furthermore, the product design did not consider improving its cleaning performance by modifying the internal core tube structure to meet the specific dust removal process requirements, resulting in inconsistent cleaning effects. In particular, it is inconvenient to clean the dust collector bags used in asphalt mixing plants, as the flat bags make them impractical. Therefore, there is an urgent need for a multi-functional pneumatically controlled dust collector bag cleaning and inflatable cannon to improve these issues. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-functional pneumatically controlled dust collector bag cleaning and inflation cannon. The bottom of the air storage mechanism is positioned on the corresponding dust collector bag opening plate. Compressed air is discharged into the air storage mechanism through the air inlet mechanism to make the air pressure in the air storage mechanism reach the preset requirements. Then, the compressed air in the air storage mechanism is released instantly through the jetting mechanism, so that the air in the air storage mechanism is quickly discharged into the dust collector bag to clean the dust on the dust collector bag, thereby improving the practicality of the equipment.

[0006] This utility model relates to a multi-functional pneumatically controlled dust collector bag cleaning and inflation cannon, which includes an air storage mechanism; it also includes an air jet mechanism and an air intake mechanism, both of which are mounted on the air storage mechanism.

[0007] The air intake mechanism regulates the pressure inside the air storage mechanism, and the jetting mechanism works with the air storage mechanism to spray gas into the dust collection bag to clean the dust collection bag.

[0008] The bottom of the air storage mechanism is positioned on the corresponding dust collector bag opening plate. Compressed air is discharged into the air storage mechanism through the air inlet mechanism to make the air pressure in the air storage mechanism reach the preset requirements. Then, the compressed air in the air storage mechanism is released instantly through the jetting mechanism, so that the air in the air storage mechanism is quickly discharged into the dust collector bag to clean the dust on the dust collector bag, thereby improving the practicality of the equipment.

[0009] Preferably, the air storage mechanism includes a cylinder, an ear seat, a cage seat, and a core tube. The ear seat is installed at the bottom of the cylinder, and an air jet port is provided at the bottom of the cylinder. The cage seat is installed on the ear seat, and the core tube is installed in the cylinder, with the bottom end of the core tube connected to the air jet port of the cylinder. The cage seat is positioned on the corresponding dust collector bag opening plate, so that the cylinder stores compressed air. Then, the compressed air in the cylinder is quickly discharged into the core tube through the air jet mechanism. After the compressed air flows through the core tube, it is discharged into the dust collector bag through the air jet port of the cylinder to clean the dust on the dust collector bag.

[0010] Preferably, the core tube has a venturi structure inside; this facilitates increasing the speed at which air enters the dust collector bag through physical pressurization, thereby allowing the air around the cage to enter the dust collector bag along with the air ejected from the core tube, thus improving the dust removal effect.

[0011] Preferably, the jetting mechanism includes a pneumatic pulse valve, a pulse valve cover, and a pneumatic switch. Both the pneumatic pulse valve and the pulse valve cover are installed on the top of the cylinder, with the pulse valve cover fitted onto the pneumatic pulse valve. The top of the pneumatic pulse valve has a connection port, and the bottom has an air inlet and an exhaust port. The air inlet of the pneumatic pulse valve is located inside the cylinder, and the exhaust port is located inside the core tube. The pneumatic switch is installed on the cylinder and connected to the connection port of the pneumatic pulse valve via a connecting pipe. In use, the operator presses the pneumatic switch to open the pneumatic pulse valve, rapidly discharging compressed air from the cylinder into the core tube. After flowing through the core tube, the compressed air is then sprayed into the dust collector bag through the jetting port of the cylinder, thereby improving the practicality of the equipment.

[0012] Preferably, the air intake mechanism includes an air intake valve, an air intake pipe, a pressure gauge, and a pressure relief valve. The air intake valve, pressure gauge, and pressure relief valve are all installed on the cylinder body, and the pressure relief valve communicates with the interior of the cylinder body. The air intake valve communicates with the interior of the cylinder body through the air intake pipe. When the air intake valve is connected to an air source and opened, compressed air passes through the air intake valve and the air intake pipe in sequence before entering the cylinder body, causing the pressure inside the cylinder body to rise. At the same time, the pressure inside the cylinder body is monitored by the pressure gauge, which facilitates the operator to judge the pressure inside the cylinder body. Furthermore, during the air intake process, if the pressure inside the cylinder body exceeds the threshold of the pressure relief valve, the pressure relief valve opens to discharge the excess gas inside the cylinder body, thereby improving the safety of the equipment.

[0013] Preferably, the cylinder is provided with a handle, and the pneumatic control switch is installed on the cylinder; during use, the operator holds the handle to operate the equipment, thereby improving the practicality of the equipment.

[0014] Preferably, it also includes a dual-channel base, which is installed on the ear seat and the top of the dual-channel base is connected to the air jet port of the cylinder; by replacing the cage seat with a dual-channel base, it is convenient to clean the dust collector bags used in the asphalt mixing plant, thereby improving the practicality of the equipment for multi-condition dust removal.

[0015] Preferably, the cylinder is provided with a nameplate holder; this facilitates the installation of the equipment's nameplate on the nameplate holder, thereby improving the equipment's practicality.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. It adopts a pneumatic pulse valve, which is convenient to use in the absence of power supply, suitable for explosion-proof conditions, and does not require batteries, which reduces production costs and increases transportation convenience;

[0018] 2. The dual-channel base facilitates cleaning of the dust collector bags used in asphalt mixing plants;

[0019] 3. The cage base can be replaced according to the actual type of dust collector bag, improving the applicability of the equipment;

[0020] 4. The internal core tube is designed with a venturi tube to cope with more working conditions and enhance its applicability.

[0021] 5. The product's performance has been optimized and its functions improved. In addition to cleaning the dust from the dust collector bags, it can also separate the ribs that hold the bags together when replacing old bags, and it also has the function of checking for leaks in the bags.
