Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth bag dust collector, and particularly relates to a cloth bag dust collector with dust collection function. BACKGROUND

[0002] The cloth bag dust collector is a high-efficiency dust removal equipment, which realizes purification by filtering dust-containing gas through a dust removal cloth bag. After the dust-containing gas flows into the equipment, part of large particles is settled due to the reduction of flow rate, and fine dust is intercepted outside the bag when passing through the filter bag with the airflow. The clean gas is discharged through the inside of the filter bag. The structure mainly comprises a shell, a filter bag assembly, a dust removal device and the like. The filter bag is made of polyester, polypropylene and the like. The dust removal method is pulse blowing, mechanical vibration and the like. The dust removal equipment can effectively treat dust exhaust gas in the metallurgy, chemical industry, cement and the like. The cloth bag dust collector has the characteristics of high dust removal efficiency, strong adaptability, stable operation and the like. The filter bag material and dust removal frequency can be adjusted according to the working condition. The cloth bag dust collector is an environmental protection equipment widely used in industrial dust removal.

[0003] The conventional dust collector shell lacks the dust collection function. Coarse dust falls into the ash bucket under the action of gravity along the inner wall of the dust collector shell. However, fine dust on the surface of the filter cloth is scattered in the dust collector shell under the blowing of the blowing pipe and is not easy to fall into the ash bucket. The fine dust is easily mixed into the newly entering flue gas, increases the amount of dust in the flue gas, increases the dust removal difficulty of the cloth bag dust collector, and even blocks the filter cloth in severe cases, reduces the filtering speed, accelerates the aging of the dust collector, and reduces the service life. Therefore, the present application provides a cloth bag dust collector with dust collection function. SUMMARY

[0004] To solve the above technical problems, the present application provides a cloth bag dust collector with dust collection function, comprising:

[0005] The inner side of the mounting clamp is fixedly connected with the shell.

[0006] The dust removal mechanism is arranged in the shell, and the dust removal mechanism is fixedly connected with the inner side of the shell.

[0007] The flow guide mechanism is fixedly connected with the outer side of the shell, and the flow guide mechanism is arranged above the mounting clamp.

[0008] The separation mechanism is arranged below the mounting clamp, and the separation mechanism is fixedly connected with the inner side of the shell.

[0009] The dust removal mechanism comprises:

[0010] The dust removal bag is arranged in the shell, a plurality of dust removal bags are arranged, the dust removal bags are uniformly distributed in the shell, and the outer side of the dust removal bag is in a wave shape.

[0012] The waste gas enters the flow guide mechanism, and the waste gas enters the shell from the upper middle part of the shell through the flow guide mechanism. The flow guide mechanism drives the waste gas to generate a cyclone, so that the waste gas uniformly contacts the plurality of dust removal bags. The waste gas enters the dust removal bag, and the particulate impurities are left inside the shell. The particulate impurities are settled to the bottom of the shell under the action of gravity. The separation mechanism receives the settled particulate impurities, collects and temporarily stores them, and orderly discharges them. The mounting assembly stably supports the dust removal bag to ensure that it maintains the form during waste gas filtration. The rotating airflow can uniformly contact the plurality of dust removal bags and strip the particulate impurities adhered to the surface of the dust removal bag, so as to ensure that the dust removal bag continuously and efficiently filters. After the waste gas is purified by the dust removal bag, the clean gas is discharged from the top of the shell, and the dust removal process is completed. The dust removal bag with the wave-shaped surface can significantly increase the contact area with the airflow in a limited space, and better dust removal and filtration effect is obtained. The rotating airflow cooperates with the wave-shaped surface. The airflow flows along the wave-shaped contour of the dust removal bag. The flow rate is accelerated at the wave peak to form a strong scouring force. The vortex is generated at the wave valley due to the rotation of the airflow. The stirring action of the vortex can loosen the adhered particulate impurities. The concave-convex structure of the wave-shaped surface changes the direction of the airflow, so that the impurities are subjected to alternating pneumatic forces, and better stripping effect is obtained.

[0013] Further, the mounting assembly comprises a fixed plate fixedly connected with the inner side of the shell. End faces of the fixed plate are provided with countersunk holes, which are uniformly distributed on the end faces of the fixed plate. The inner side of the countersunk hole is in sliding connection with the outer side of the dust removal bag. The outer side of the dust removal bag is fixedly connected with a limiting plate. The outer side of the limiting plate is in sliding connection with the inner side of the countersunk hole. During installation, the dust removal bag is inserted into the countersunk hole, and the limiting plate is clamped into the large diameter of the countersunk hole, so as to complete the limiting of the dust removal bag.

[0014] Further, the side of the fixed plate away from the installation card is provided with a hole plate. The hole plate is arranged directly above the fixed plate. The side of the hole plate close to the fixed plate is fixedly connected with a limiting column. The side of the fixed plate close to the limiting column is provided with a limiting hole.

The rice board is slidably connected with the trough of the wave-shaped inner side of the dust removal bag, and the end of the rice board is half of the trough of the wave-shaped surface of the dust removal bag. The rice board is fixedly connected with the inner side of the hole plate away from the separation mechanism. The rice board supports the wave shape of the dust removal bag, thereby further maintaining the wave shape structure of the dust removal bag and maintaining the filtering effect. The adjacent rice boards are staggered, and the end of the rice board is half of the concave of the wave-shaped surface of the dust removal bag. The adjacent two rice boards cooperate to support all the concave of the dust removal bag. The rice board can support the dust removal bag through fewer ends, reduce the blockage of the airflow after filtration, and ensure the rapid passage of the gas.

[0016] Further, the inner side of the countersunk hole is fixedly connected with a limiting strip, the limiting strip is uniformly distributed along the circumference of the countersunk hole, and the limiting strip is arranged at the trough of the outer side of the dust removal bag. The surface of the limiting strip is slidably connected with the outer side of the dust removal bag. The limiting strip is arranged on the side of the limiting plate away from the hole plate. The limiting strip can limit the wave trough of the dust removal bag. The limiting strip cooperates with the rice board to maintain the inner and outer sides of the dust removal bag, thereby further maintaining the wave shape structure of the dust removal bag.

The inner cavity of the air inlet pipe is in communication with the inner cavity of the shell. The top of the shell is fixedly connected with an air outlet pipe, and the inner cavity of the air outlet pipe is in communication with the inner cavity of the shell. The exhaust gas enters the shell from the middle and upper part of the shell through the air inlet pipe, and then is filtered by the dust removal bag. Then the exhaust gas enters the position above the mounting clamp in the shell, and then exits through the air outlet pipe.

[0018] Further, the inner side of the shell is provided with a ring groove, and the inner cavity of the air inlet pipe is in communication with the ring groove. The inner side of the shell is provided with a gas cavity, and the gas cavity is spirally arranged. The gas cavity is uniformly distributed along the circumference of the ring groove. The exhaust gas enters the air inlet pipe, then enters the ring groove, and then enters the gas cavity. The airflow enters the inside of the shell along the spiral gas cavity, thereby generating a rotational flow. The rotational flow can make the exhaust gas uniformly contact the plurality of dust removal bags, and cooperate with the wave-shaped surface of the dust removal bag to strip the impurities adhered to the surface of the dust removal bag.

[0019] Further, the inner side surface of the ring groove is rotationally connected with a ring cylinder, and the ring cylinder and the ring groove form a closed cavity, the outer side surface of the ring groove is fixedly connected with a fan blade, and the fan blade is uniformly distributed along the circumference of the ring groove, the airflow enters the air cavity, the air cavity generates suction force on the fan blade, thereby driving the fan blade to rotate, the rotating fan blade drives the ring cylinder to rotate, and the rotating fan blade can disturb the waste gas in the ring groove, avoiding the settlement of particulate waste and the blockage of the ring groove and the air cavity.

[0020] Further, the separation mechanism comprises a dust treatment structure arranged at the bottom of the shell, the outer side surface of the dust treatment structure is fixedly connected with the inner side surface of the shell, the bottom of the shell is tapered, and the inner side surface of the shell is fixedly connected with an oscillating plate, the oscillating plate is provided in a plurality of forms, and the plurality of oscillating plates are arranged in a conical ring shape, the inner diameter of the plurality of ring-shaped oscillating plates gradually decreases from one side close to the dust treatment structure, and the oscillating plate is arranged in a wave shape, when the dust-containing waste gas enters the shell and forms a cyclone, the particulate impurities are settled to the tapered bottom of the shell under the action of centrifugal force and gravity, in the settlement process, the impurity particles carried by the airflow collide with the wave-shaped oscillating plate, and since the oscillating plate is conical and the inner diameter gradually decreases, the airflow repeatedly changes the flow direction and speed when passing through each layer of the oscillating plate, forming a turbulent flow and vortex area, so that the particles deviate from the flow line due to inertia, and the kinetic energy of the particles is attenuated after colliding with the wave-shaped surface of the oscillating plate, and the particles are more easily separated from the airflow and fall into the dust treatment structure, the wave-shaped structure and the gradually decreasing inner diameter buffer the rebound of the settled particles between the oscillating plates, reducing secondary lifting, thereby further improving the separation effect.

[0021] Further, the inner side surface of the oscillating plate is fixedly connected with a separation cylinder, the outer side surface of the separation cylinder is fixedly connected with an elastic rod, the elastic rod is arranged at the interval between adjacent oscillating plates, and the end of the elastic rod away from the separation cylinder is fixedly connected with the inner side surface of the shell, the airflow drives the oscillating plate to oscillate, drives the separation cylinder to oscillate, and pulls the elastic rod to deform, the deformation and reset process of the elastic rod form a periodic reciprocating tension, so that the oscillation amplitude of the separation cylinder and the oscillating plate increases, and the shaking off effect of the adhered dust is enhanced, when the airflow impacts the wave-shaped surface of the oscillating plate, the elastic buffer of the elastic rod avoids the rigid collision of the oscillating plate with the shell, at the same time, the deformation energy of the elastic rod is converted into oscillation kinetic energy, maintaining long-time continuous vibration, ensuring that the dust is accelerated to separate in the centrifugal settlement process due to the high-frequency vibration of the oscillating plate, and effectively preventing the dust from accumulating on the surface of the oscillating plate and the separation cylinder.

[0022] The present application has the following beneficial effects:

[0023] 1. The present application can significantly increase the contact area with airflow in limited space by setting dust removal mechanism and wave-shaped surface dust removal bag, and obtain better dust removal and filtering effect. Rotating airflow cooperates with wave-shaped surface, airflow flows along the wave-shaped contour of the dust removal bag, the flow rate is accelerated at the wave crest to form strong scouring force, and vortex is generated at the wave trough due to airflow rotation. The stirring action of the vortex can loosen adhered particulate impurities. The concave-convex structure of the wave-shaped surface changes the airflow direction, so that the impurities are subjected to alternating aerodynamic force, and better stripping effect is obtained.

[0024] 2. The present application further maintains the wave-shaped structure of the dust removal bag and maintains the filtering effect by setting the rice-shaped plate to support the wave shape of the dust removal bag. Adjacent rice-shaped plates are staggered, and the end of the rice-shaped plate is half of the wave-shaped recess of the dust removal bag. The adjacent two rice-shaped plates cooperate to support all recesses of the dust removal bag, so that the rice-shaped plate can support the dust removal bag through fewer ends, reduce the obstruction to the filtered airflow, and ensure the rapid passage of the gas.

[0025] 3. The present application generates cyclone by setting the flow guide mechanism, so that the airflow enters the inside of the shell along the spiral air cavity, the cyclone can make the exhaust gas uniformly contact the several dust removal bags, and cooperate with the wave-shaped surface of the dust removal bag to strip the impurities adhered to the surface of the dust removal bag. The air cavity generates suction force on the fan blade to drive the fan blade to rotate. The rotating fan blade rotates the ring cylinder, and the rotating fan blade can disturb the exhaust gas in the ring groove to avoid the settlement of particulate waste and avoid the blockage of the ring groove and the air cavity.

[0026] 4. The present application generates turbulence and vortex area by setting the separation mechanism, so that the particulate impurities carried by the airflow collide with the wave-shaped oscillating plate during the sedimentation process. Since the oscillating plate is in the form of a conical ring with a gradually reduced inner diameter, the airflow repeatedly changes direction and speed when passing through each layer of oscillating plate, forming turbulence and vortex area. The particles deviate from the flow line due to inertia, and the kinetic energy is attenuated after impacting the wave-shaped surface of the oscillating plate, so that the particles are more easily separated from the airflow and fall into the inside of the dust treatment structure. The wave-shaped structure and the gradually reduced inner diameter buffer the rebound of the settled particles between the oscillating plates, reducing the secondary lifting, thereby further improving the separation effect.

[0027] 5. The present application increases the oscillation amplitude of the separation cylinder and the oscillating plate by setting the elastic rod, and enhances the shaking effect of the adhered dust. When the airflow impacts the wave-shaped surface of the oscillating plate, the elastic buffer of the elastic rod avoids the rigid collision of the oscillating plate with the shell, and at the same time, the deformation energy of the elastic rod is converted into oscillation kinetic energy, maintaining long-time continuous vibration, ensuring that the dust is accelerated to separate from the centrifugal sedimentation process due to the high-frequency vibration of the oscillating plate, and effectively preventing the dust from accumulating on the surface of the oscillating plate and the separation cylinder.
