[0002] The tail gas treatment in molecular sieve production equipment is all equipped with bag dust collectors. The ash hopper of the current bag dust collector cleaning device is a tetrahedron inverted cone. The fine powder in the ash hopper has high ignition loss, fine particles, material cooling, etc., which causes bridges or adheres to the wall, and then blockage occurs. The material entering the furnace barrel is sometimes more and sometimes less, and it is very easy to block the furnace head and tail. At present, the workshop prevents the bag dust collector from blocking and bridging the ash hopper by equipping the ash hopper with a mechanical vibrator and manual handling. Among them, the long-term use of the mechanical vibrator causes fatigue stretching of the bag dust collector cleaning hopper (stainless steel plate), a decrease in tensile strength, and cracks in the steel plate (steel plate welding repair 6 times / year, local steel plate replacement 2 times / year), affecting the normal operation of the bag dust collector; manual handling is prone to generate unorganized dust emissions on site (3 times / month), polluting the environment, and is labor-intensive.

[0022] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0023] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the implementation methods in the specification are only part of the implementation methods of the present invention, not all of the implementation methods.

[0024] Combine Figure 1 and Figure 2 As shown, the bag dust collector provided by the embodiment of the present invention includes a dust collector body 1 and at least one fluidizing member 2 arranged inside the dust collector body 1, wherein the fluidizing member 2 is arranged at a position at the bottom of the dust collector body 1 that is prone to clogging, that is, the fluidizing member 2 is arranged at a constricted position at the bottom of the dust collector body 1. The fluidizing member 2 includes an air supply pipe 21 and a diversion pipe 22. The air supply pipe 21 is passed through the inner wall of the dust collector body 1 and is used to introduce compressed gas, that is, one end of the air supply pipe 21 passes through the interior of the dust collector body 1, and the other end of the air supply pipe 21 extends out of the dust collector body 1. The end of the air supply pipe 21 extending out of the dust collector body 1 is directly or indirectly connected to an air source for introducing compressed gas. The shunt pipe 22 is provided at one end of the air supply pipe 21 extending into the interior of the dust collector body 1, and the air supply pipe 21 is connected to the shunt pipe 22 so that the compressed gas introduced through the air supply pipe 21 can enter the shunt pipe 22 and flow out through the air outlet of the shunt pipe 22. The air outlet end of the shunt pipe 22 faces the inner wall of the dust collector body 1, so that the compressed gas flowing out through the air outlet of the shunt pipe 22 flows toward the inner wall of the dust collector body 1, so as to act on the powder inside the dust collector body 1, loosening the powder so that the powder falls under the action of its own gravity. A control component for controlling the on and off of the compressed gas is provided on the air supply pipe 21. The on and off of the compressed gas can be controlled by the control component, thereby selectively providing compressed gas, reasonably controlling the amount of compressed gas, saving costs, and intermittently supplying compressed gas to avoid generating a continuous airflow, thereby avoiding affecting the falling of the powder.

[0025] The bag dust collector provided by the present invention is provided with a fluidizing member 2 inside the dust collector body 1, and compressed gas can be introduced into the interior of the dust collector body 1 through the air supply pipe 21 and the diversion pipe 22, so that the compressed gas is ejected along the inner wall of the dust collector body 1 and directly acts on the powder. Due to the change of the airflow, the edge of the diversion pipe 22 will produce high-frequency vibration, so that the fluidizing member 2 can produce both blowing and vibrating actions at the same time, effectively promoting the downward flow of the powder, and playing a role in preventing or reducing the blockage and bridging of the bag dust collector. This method does not require the vibration of the bag dust collector, thereby ensuring the service life of the bag dust collector. In addition, no manual participation is required, reducing labor costs and labor intensity, and the powder will not leak, avoiding environmental pollution.

[0026] In some embodiments, the dust collector body 1 has four side walls. In this case, there are four fluidizing members 2 , which are respectively arranged on the four side walls of the dust collector body 1 , and each fluidizing member 2 is provided with a control member.

[0027] Under this design, compressed gas can be provided to the powder at the four inner wall positions of the dust collector body 1 through the four fluidizing parts 2 respectively, so that the compressed gas acts directly on the powder, loosens the powder at the corresponding positions, and then makes the powder fall under the action of its own gravity, avoiding the phenomenon of powder sticking to the wall and the phenomenon of powder arching, ensuring the feeding effect of the powder, and each fluidizing part 2 is provided with a control part to control whether the corresponding fluidizing part 2 blows out compressed gas, which is convenient for the control of compressed gas supply. Selective gas supply or cyclic gas supply can be used according to actual needs to reduce the cost of compressed gas.

[0028] In some embodiments, four fluidizing elements 2 are staggered in the vertical direction.

[0029] Under this design, the four fluidizing members 2 can provide compressed gas to the powder at different positions of the vertical section, thereby loosening the powder at different positions on the inner wall of the bag filter, thereby ensuring the falling effect of the powder.

[0030] In some embodiments, the vertical height of the four vulcanizing parts gradually decreases in a clockwise or counterclockwise direction. At this time, the control parts on the four fluidizing parts 2 are intermittently opened in a clockwise or counterclockwise direction to ensure that the powder is loosened and then gradually works under the action of its own gravity until it is discharged through the bottom of the dust collector body 1.

[0031] In some embodiments, the bag filter further includes a main pipe 23 for introducing compressed gas, and the air supply pipes 21 of the four fluidizing elements 2 are all connected to the main pipe 23. The air inlet end of the main pipe 23 is connected to an air source, which can be industrial gas or the like, and can be selected according to actual needs.

[0032] In this design, compressed gas can be provided through the main pipe 23, and then the compressed gas enters the corresponding gas supply pipe 21, which is convenient for gas supply.

[0033] In some embodiments, the gas supply pipe 21 is communicated with the main pipe 23 through the hose 24.

[0034] In this design, the connection angle between the main pipe 23 and the gas supply pipe 21 can be changed through the hose 24, which is convenient for arranging the gas supply pipe 21 and the main pipe 23.

[0035] In some embodiments, a manual valve 25 for controlling the on-off of compressed gas is arranged between the hose 24 and the main pipe 23. The manual valve 25 is in a normally open state, which ensures the normal delivery of compressed gas.

[0036] In this design, the manual valve 25 can be used to control the gas supply of compressed gas, so that the corresponding airway of the manual valve 25 can be operated to meet the use requirements under different working conditions when needed.

[0037] In some embodiments, the control member includes a pulse electromagnetic valve arranged on the gas supply pipe 21. The pulse electromagnetic valve is a conventional valve structure, which inputs a positive pulse signal into the coil in the electromagnetic valve body through a wire. The working magnetic flux generated by the coil makes the moving core attract and open the valve. When the positive pulse signal input is stopped, the moving core is released and returns to the initial state under the action of the spring force, closing the valve. It is a conventional component in the art, and its structure and working principle are not described in detail here. In this application, the corresponding gas supply pipe 21 can be selectively opened by the pulse electromagnetic valve to realize automatic control.

[0038] In some embodiments, as shown in Figure 1 and Figure 2 The end of the shunt pipe 22 is connected with two shunt pipes 22, the two shunt pipes 22 are oppositely arranged, and the two shunt pipes 22 extend along the slope direction of the inner wall of the dust collector body 1.

[0039] In this design, the two shunt pipes 22 form a straight line shape, which avoids affecting the normal falling of the powder, and the shunt pipe 22 can provide compressed air to the powder along the corresponding two directions, which ensures the effect on the powder.

[0040] In some embodiments, the shunt pipe 22 is in a flat tube shape. Specifically, the end of the shunt pipe 22 is in a flat tube shape.

[0041] Under this design, the end of the diverter pipe 22 is relatively thin. When the compressed gas is ejected through the end of the diverter pipe 22 and acts on the inner wall of the dust collector body 1, due to the change of the airflow, the end of the diverter pipe 22 will generate high-frequency vibration, so that the powder pressed on the diverter pipe 22 will loosen under the vibration, thereby ensuring the falling effect of the powder.

[0042] In some embodiments, the diversion pipe 22 is disposed close to the inner wall of the dust collector body 1 .

[0043] In this way, the diverter pipe 22 is prevented from affecting the normal falling of the powder, and the diverter pipe 22 is close to the inner wall of the dust collector body 1, so that after the compressed gas ejected through the diverter pipe 22 acts on the inner wall of the dust collector body 1, the airflow acts on the powder on the inner wall of the dust collector body 1 while being able to flow back and act on the diverter pipe 22, so that the diverter pipe 22 can generate high-frequency vibration under the change of airflow, thereby increasing the loosening effect of the powder.

[0044] Taking a roaster as an example, a comparison of roaster A using the bag filter of this application with a conventional bag filter revealed that the accumulation or bridging period in roaster A, which used the bag filter of this application, exceeded 30 days. In contrast, roaster B, which used a conventional bag filter, processed the accumulated material multiple times within a month, increasing roaster production capacity by 1%. In terms of quality, roaster A significantly outperformed roaster B. The crystallinity and unit cell constant of the Y-type molecular sieve in roaster A were 3% higher than those in roaster B, resulting in a more ideal roasting effect and reaction state.

[0045] The bag dust collector provided by the utility model has a simple structure and is easy to install, can basically solve the problems of blockage and uneven material discharge, equipment damage, and unorganized dust emission, and improves the quality of molecular sieves.
