Description

Technical Field

[0001] The invention relates to the technical field of pneumatic ash conveying equipment, in particular to pneumatic ash conveying equipment and a method using a spherical air lock valve. Background Art

[0002] When the waste gas with a high dust concentration is output and processed, pneumatic ash conveying equipment will be used for treatment, such as pulse dust removal equipment, which uses pneumatic conveying of dust-containing waste gas. During transportation, the dust in the gas is removed by material adsorption, and then the dust removal gas is discharged conveniently. Pulse blowing is usually used for cleaning.

[0003] For example, in an energy-saving and safe pulse bag dust collector disclosed in the existing patent announcement number CN112604404B, dust-containing air enters the dust collector shell from the air inlet, and dust particles with larger diameters are deposited in the ash hopper in the lower half of the dust collector shell, while dust particles with smaller diameters flow to the filter bag with the flow of air. The dust will be retained on the surface of the filter bag, and the clean air will pass through the filter bag and then be introduced into the clean air chamber through the air guide sleeve for discharge. When the specified cycle is reached, the pulse ventilation valve opens, and the compressed air in the compressed air bag enters the injection pipe through the ventilation pipe and the air distribution pipe. The compressed air is blown to the filter bag through the air holes on the injection pipe, and the dust retained on the surface of the filter bag is blown into the ash hopper. This cycle is repeated to achieve pulse dust removal. Each filter bag is provided with a injection pipe, which is connected to the air distribution pipe. Air holes are opened on the circumference of the injection pipe. Support arms are also arranged at intervals on the circumference of the injection pipe. The free abutment of the support arms against the inner wall of the filter bag can ensure that the filter bag made of soft material is always in an open state, thereby increasing its filtration area and ensuring that the dust can be blown off during pulse blowing.

[0004] The above-mentioned dust collector can remove dust from dusty air and clean the filter bag by blowing. Although the support arm can open the filter bag, it will affect the effective removal of dust on the surface of the filter bag during cleaning. The dust on the outer surface of the contact between the filter bag and the support arm is not easy to blow off. In addition, each group of filter bags is equipped with a blowing pipe and a support arm, which increases the setting of the internal parts of the filter bag, affects the smooth discharge of the gas after filtration, and is also more cumbersome during subsequent disassembly. In view of the above problems, a pneumatic ash conveying device and method using a spherical air lock valve is proposed. Summary of the invention

The frame 13 plays a supporting role, and the dust removal box 11 is connected to the inside of the ash hopper 12;

[0031] like Figure 2 As shown, a spherical air lock valve 16 is installed on the air inlet pipe 15. The spherical air lock valve 16 is installed and used by selecting an existing suitable spherical air lock valve. When the valve is closed, the valve disc rotates 90° to the closed position. After receiving the in-place signal, 0.6MPa of compressed air is filled into the diaphragm sealing ring, which undergoes elastic deformation and fits tightly with the valve disc to achieve sealing. When the valve is opened, the compressed air in the diaphragm sealing ring is depressurized and retracts by its own elasticity. Then, the cylinder acts after a delay of several seconds, and the ball rotates 90° to the open position. Since the valve disc does not contact the diaphragm sealing ring, the opening and closing torque is small, and the wear is small, thereby increasing the service life and greatly reducing the maintenance cost and time. The cylinder in the spherical air lock valve adopts a fully enclosed rotary push rod straight cylinder drive to achieve trajectory conversion and rotary output in the enclosed cavity. Even under harsh working conditions with high dust concentration, internal leakage will not occur due to wear of the seal, thereby ensuring the reliability of the valve action and being suitable for use in ash conveying systems.

[0043] In one embodiment, Figure 3 As shown, the mounting frame includes a fixing plate 26, and the inner wall of the dust removal box 11 is connected to a support frame 27 for supporting the fixing plate 26. The fixing plate 26 is provided with a plurality of mounting holes for mounting the filter bag 28. The bottom of the mounting plate 25 is provided with an annular groove for placing the filter bag 28 extending out of the top of the fixing plate 26;

[0044] The installation of the filter bag 28 and the fixed plate 26 can refer to the installation of the filter bag 28 in the existing pulse dust collector. After the filter bag 28 is installed, a portion of the top will protrude from the fixed plate 26, and the annular groove at the bottom of the mounting plate 25 can be opened with a groove corresponding to the filter bag 28, which is used for the mounting plate 25 to be stably placed on the top of the fixed plate 26.

Due to the inertia, the coarse dust particles in the gas flow directly into the ash hopper 12, which plays a role in pre-dust collection. The air flow entering the ash hopper 12 is then turned upward and passes through the filter bag 28. The gas enters the inner cavity of the filter bag 28 after being filtered by the filter bag 28 and is discharged from the air port on the gear 31 to the ventilation cavity 29, and then enters the buffer box 17 and is discharged from the air outlet pipe 18.

[0049] When the filter bag 28 is cleaned by spraying, the spherical air lock valve 16 is closed, the pulse spraying part works, and the compressed air enters the filter bag 28 through the ventilation chamber 29. At the same time, the hydraulic cylinder 21 can control the extension and retraction of the piston rod. During the reciprocating extension and retraction process of the piston rod, the reciprocating horizontal movement of the connecting rod 22 can be driven by the push rod 23, thereby driving the rack 32 to slide back and forth in the slide groove 33, and the gear 31 rotates back and forth, thereby driving the bag cage 30 to rotate back and forth, so that the gas entering the filter bag 28 during spraying can be evenly discharged into the dust removal box 11 through the filter bag 28, and during the rotation of the bag cage 30, the filter bag 28 can be assisted to shake, and the filter bag 28 can be shaken and cleaned with the compressed air, and the dust on the filter bag 28 falls into the ash hopper 12 for collection, and then the discharge valve is opened to discharge the dust from the ash hopper 12.
