Description
Technical Field
The invention relates to a dust purifying and separating technology, in particular to vertical filter cylinder type dust treatment equipment and a treatment method thereof.
Background
The filter cartridge type dust treatment equipment can be seen everywhere in industries such as grains, food factories, rubber, welding and the like, and three common filter cartridge dust collectors are provided:
1. the vertical filter cartridge dust remover is commonly used for single-machine equipment, and dust is easy to clean and settle to an ash bucket, so that the effect is good. The installation mode is also a common mode aiming at the working condition with slightly high dust concentration in the filter cylinder;
2. The inclined filter cartridge dust remover has the advantages that the filter cartridges are overlapped up and down, the structure is compact, the occupied area is small, the cartridge replacement is convenient, but when ash is removed, dust removed from the upper filter cartridge is deposited on the lower filter cartridge, and the dust is difficult to remove;
3. The horizontal filter cartridge dust remover is suitable for non-sticky, low-concentration and coarse powder dust removal of a medium-small dust removal system, is also suitable for reconstruction of some old bag dust removers, and is more difficult to remove dust at the upper part of a lower filter cartridge.
In either form, the principle is approximately the same, and the dust enters the dust chamber through negative pressure airflow generated by the fan, is filtered and separated into the clean chamber through the filter cartridge and is completed through the fan. Dust is blocked on the surface by the filter element, and when the blocked dust continuously deposits and falls, purified air is discharged by the air duct and the fan.
In the practical application process, the filter cylinder is often blocked, and once the filter cylinder is blocked, a specific differential pressure value needs to be monitored by means of a differential pressure sensor, and after the differential pressure value reaches a preset value, a control system is used for generating pulse airflow to reversely purge, so that blocked dust is discharged outwards.
Due to the working environment, a series of induction components are required to be checked one by one in the environments of dust emission, high temperature, humidity and the like, and particularly, faults are frequently caused to large-scale equipment with high integration level of a circuit control module, so that the fault is very troublesome.
In addition, in the process of the action of the pulse airflow, the flow direction of the pulse airflow is opposite to the induced air direction of the fan, so that the fan needs to be stopped, restarted after cleaning, and the failure rate of the fan can be increased due to frequent restarting under the working condition of higher dust concentration.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
Referring to fig. 1 to 22, as an embodiment of the present invention, the vertical filter cartridge type dust treatment apparatus includes a frame 1;
A partition plate 8 is arranged at the top of the frame body 1, a box body 2 is arranged above the partition plate 8, an ash bucket 3 is arranged below the partition plate 8, and the partition plate 8 divides the ash bucket 3 and the box body 2 into a clean room and an air ash room;
The filter tank 9 is provided with a plurality of filter holes, a filter element is arranged in the filter tank 9, and an opening is formed in the bottom of the filter tank 9;
the lower end of the filter tank 9 extends into the gas ash chamber, and the upper part of the filter tank 9 is positioned in a clean room;
The air inlet end of the induced draft fan 5 is connected with the clean room through a first air suction pipe 7 and an air tank 6 in sequence, a first valve group is arranged at the joint of the air inlet end of the induced draft fan 5 and the first air suction pipe 7, and the first valve group is also connected with the air ash room through a second air suction pipe 11;
an air inlet 12 is arranged at one side of the ash bucket 3, and the valve group I is in a normally open state between the air inlet end of the induced draft fan 5 and the first air suction pipe 7;
When the pressure difference between the clean room and the ash chamber reaches a preset value, the valve group I acts to disconnect the air inlet end of the induced draft fan 5 from the first air suction pipe 7 and to connect the air inlet end of the induced draft fan 5 with the second air suction pipe 11 to close the air inlet 12, and when the pressure difference between the clean room and the ash chamber is eliminated, the valve group I acts reversely to switch the air inlet end of the induced draft fan 5 to connect with the first air suction pipe 7 again and disconnect the air inlet 12 from the second air suction pipe 11.
In this embodiment, in the initial stage of operation, the air in the clean room is sucked by the induced draft fan 5, and the air in the air ash room is led into the clean room through the filter tank 9, the air in the air ash room is led into the filter tank 9 from the opening at the bottom of the filter tank 9, dust in the turbid air is filtered Kong Lanjie and gathered by the filter element in the filter tank 9 and the filter surface of the filter tank 9 to fall to the bottom of the ash bucket 3, and as the clean air in the air ash room continuously flows into the clean room, the air pressure in the air ash room is reduced, and the turbid air is continuously sucked through the pipeline connected with the air inlet 12.
With the continuous operation of the device, the filter element and the filter hole in the filter tank 9 are continuously blocked, so that the total cross section of the conduction between the clean room and the air ash chamber is continuously reduced, negative pressure is generated in the clean room, dust blocked in the filter element and the filter hole is stubborn to be adhered in the filter element and the filter hole under the action of air suction force generated by the pressure difference between the clean room and the air ash chamber, and the air ash chamber is kept at normal pressure because the air inlet 12 is communicated with the turbid environment atmosphere through a pipeline.
The filter element and the filter element are blocked, so that the negative pressure in the clean room is continuously enhanced, after the negative pressure in the clean room reaches a preset value, the valve group I is quickly operated, the induced draft fan 5 continuously sucks air in the air ash room through the second air suction pipe 11, the air inlet 12 is closed, the air in the air ash room is continuously sucked away, so that the negative pressure also appears in the air ash room, when the negative pressure in the air ash room is equal to the negative pressure in the clean room, the dust is tightly plugged on the filter element and the filter element due to the fact that the dust is not naturally peeled off due to self gravity, and only when the negative pressure in the air ash room is larger than the negative pressure in the clean room and the generated pressure difference is enough to peel off the dust attached in the filter element and the filter element, the dust can be peeled off from the filter element and the filter hole.
It should be noted that, in the process of generating negative pressure in the air ash chamber, since the filter element and the filter hole are seriously blocked and the air inlet 12 is closed, the time period for generating negative pressure in the air ash chamber and reaching the stripping pressure of dust is shorter, and when the second air suction pipe 11 sucks air from the air ash chamber, part of dust in the air ash chamber is deposited at the bottom of the ash bucket 3 because the air inlet 12 is already closed, only a small amount of dust suspended in the air ash chamber passes through the second air suction pipe 11 and is discharged through the induced draft fan 5, the dust content is less, and the superposition time period is shorter, so that the air cleanliness discharged from the induced draft fan 5 is not affected basically.
According to the invention, the air flow direction can be automatically switched according to the pressure change in the clean room, so that the pressure difference between the clean room and the air ash room is exchanged, the blocked dust is automatically stripped by means of the reverse flow of the air flow, and the dust is automatically switched to a normal running state after being separated from the filter tank 9.

If the filter element and the filter hole are blocked, so that the airflow between the clean room and the air ash room is blocked, negative pressure is generated in the clean room, and the negative pressure in the clean room is continuously increased along with the continuous worsening of the blocking condition, and when the pressure generated by the negative pressure is greater than the elastic force of the buffer spring 17, the sliding cake 15 continuously slides leftwards with the first sealing ring 16, so that the negative pressure generated in the clean room is relieved.

The outer wall of the case 2 is provided with a ferrule 35, a sleeve 26 is slidably provided in the ferrule 35, a follower 25 is engaged with the upper portion of the sleeve 26, a horizontal transverse groove 2501 is provided on the follower 25, and the boss 2202 is slidably engaged with the transverse groove 2501.
Because the collar 35 is fixed, the sleeve 26 can only slide up and down, and when the lifter 22 moves up and down horizontally, the boss 2202 only slides in the transverse slot 2501, so that the boss 2202 only moves the follower 25 up and down, thereby driving the sleeve 26 to slide up and down along the collar 35.
A vertical groove 3101 is formed on the transverse moving frame 31, a sliding block 32 is slidably arranged in the vertical groove 3101, a clamping column 33 is rotatably arranged on the sliding block 32, and the clamping column 33 is in rolling fit in a track groove 3401;

The power spring 28 remains pressurized.
In this embodiment, when the filter cartridge and the filter hole are clogged, a pressure difference is generated between the clean room and the ash chamber due to a decrease in the conduction area between the clean room and the ash chamber, wherein a negative pressure is generated in the clean room while the ash chamber is kept at normal pressure. Negative pressure in the clean room is conducted to the buffer tank 13 through the gas tank 6, the negative pressure attracts the sliding cake 15 to slide horizontally along with the first sealing ring 16 to the left direction in the drawing and compress the buffer spring 17 in the buffer tank 13, the sliding cake 15 drives the telescopic rod 14 to slide horizontally and leftwards, the telescopic rod 14 drives the push-pull frame 19 and the traversing frame 31 to move horizontally and leftwards, the push-pull frame 19 drives the lifting piece 22 to move horizontally and leftwards by utilizing the two rollers 20, and the lifting piece 22 moves downwards under the action of the embedded rollers 23 and the chute 2401, namely, one end of the telescopic rod 14 extending out of the buffer tank 13 moves horizontally and approaches the buffer tank 13 along with the push-pull frame 19 and the traversing frame 31, and the lifting piece 22 moves horizontally and downwards along with the push-pull frame 19 approaching the buffer tank 13;
when the lifting member 22 moves horizontally leftwards and moves downwards, the convex column 2202 is matched with the transverse groove 2501 to drive the follower 25 to move downwards, so that the sleeve 26 is driven to move downwards, wherein the convex column 2202 horizontally slides in the transverse groove 2501, so that the follower 25 does not receive horizontal force from the convex column 2202 leftwards and only receives vertical downward force from the convex column 2202.
In the process of moving the traversing rack 31 horizontally leftwards, the sliding block 32 and the clamping column 33 are driven to move horizontally leftwards along the upper track of the track groove 3401, so that the clamping column 33 only moves horizontally leftwards, and because the clamping column 33 is embedded with the flat groove 3001, the trigger piece 30 is kept stationary in the process of moving the clamping column 33 horizontally leftwards along the upper track of the track groove 3401, and the control rod 27 fixed with one end of the trigger piece 30 is kept stationary.
Referring to the drawings, as can be seen from the foregoing, during leftward movement of the telescoping rod 14, the sleeve 26 moves downwardly while the trigger 30 and control rod 27 remain stationary, causing the upper length of power spring 28 to be further compressed.
When the clamping column 33 moves horizontally leftwards to the left corner inflection point of the track groove 3401, the compressed power storage spring 28 releases the elasticity to press the blocking part 2701 and finally drives the control rod 27 to move downwards quickly, the lower end of the control rod 27 drives the clamping column 33 to move downwards quickly along the left track of the track groove 3401 through the trigger piece 30, and the clamping column 33 drives the sliding block 32 to slide downwards along the vertical groove 3101.
When the control rod 27 moves downwards rapidly, the communication state of the first valve group is switched through the instant action of the executing piece 36, so that the air inlet end of the induced draft fan 5 is disconnected from the first air suction pipe 7, the air inlet end of the induced draft fan 5 is connected with the second air suction pipe 11, and meanwhile, the air inlet 12 is closed;
After that, the induced draft fan 5 continuously draws air in the air ash chamber, so that negative pressure is generated in the air ash chamber, when the negative pressure in the air ash chamber is larger than the negative pressure in the clean chamber and the generated pressure difference is enough to peel off dust adhered in the filter holes and the filter element, the dust can be instantaneously peeled off from the filter element and the filter holes and fall to the bottom of the ash bucket 3, the filter element and the filter holes are not blocked, namely, the clean chamber and the air ash chamber are restored to a normal conduction state.
It is emphasized that the negative pressure in the air ash chamber is larger than the negative pressure in the clean chamber, and the instant that dust attached in the filter holes and the filter element can be stripped is reached, the clean chamber is communicated with the environment atmosphere, the clean chamber in a negative pressure state is sucked from the external environment and is conducted into the air ash chamber, and the clean chamber and the air ash chamber are restored to a normal pressure state.
When the clean room and the ash chamber are restored to normal pressure, the pressure difference between the clean room and the ash chamber is eliminated, and meanwhile, the valve group I acts reversely, the valve group I is switched to the connection between the air inlet end of the induced draft fan 5 and the first air suction pipe 7 again, the air inlet end of the induced draft fan 5 is disconnected from the second air suction pipe 11, and meanwhile, the air inlet 12 is opened, and the clean room is isolated from the environment atmosphere.
It should be added that, in the process of conducting the clean room with the ambient atmosphere, the negative pressure in the clean room is continuously reduced, and the buffer spring 17 drives the sliding cake 15 to continuously slide rightwards along with the first sealing ring 16, so that the telescopic rod 14 continuously moves rightwards;
The telescopic rod 14 drives the push-pull frame 19 and the traversing frame 31 to move horizontally and rightwards, the push-pull frame 19 drives the lifting piece 22 to move horizontally and rightwards by utilizing the two rollers 20, and the lifting piece 22 moves upwards under the action of the embedded roller 23 and the chute 2401, namely, one end of the telescopic rod 14 extending out of the buffer tank 13 moves horizontally and away from the buffer tank 13 along with the horizontal movement in the process of moving away from the buffer tank 13, and the lifting piece 22 moves upwards along with the horizontal movement of the push-pull frame 19;
When the lifting member 22 moves upwards while moving horizontally to the right, the convex column 2202 is matched with the transverse groove 2501 to drive the follower 25 to move upwards, and further drive the sleeve 26 to move upwards.
In the process of moving horizontally and rightward, the sliding block 32 and the clamping column 33 are driven to move horizontally and rightward along the lower track of the track groove 3401, so that the clamping column 33 only moves horizontally and rightward, and because the clamping column 33 is embedded with the flat groove 3001, the trigger piece 30 is kept stationary in the process of moving horizontally and rightward along the lower track of the track groove 3401, and the control rod 27 fixed with one end of the trigger piece 30 is kept stationary.
Referring to the drawings, as can be seen from the foregoing, during rightward movement of the telescoping rod 14, the sleeve 26 moves upwardly while the trigger 30 and control rod 27 remain stationary, causing the underlying length of power spring 28 to be further compressed.
When the clamping column 33 moves horizontally to the right lower corner inflection point of the track groove 3401, the compressed power storage spring 28 releases the elastic force to press the blocking part 2701, finally the control rod 27 is driven to move upwards quickly, the lower end of the control rod 27 drives the clamping column 33 to move upwards quickly along the right side edge of the track groove 3401 through the trigger piece 30, and the clamping column 33 drives the sliding block 32 to slide upwards along the vertical groove 3101.
When the control rod 27 moves upwards rapidly, the communication state of the first valve group is switched through the instant action of the executing piece 36, so that the air inlet end of the induced draft fan 5 is conducted with the first air suction pipe 7 again, the air inlet end of the induced draft fan 5 is disconnected with the second air suction pipe 11, and meanwhile, the air inlet 12 is opened again.

Correspondingly, when the control rod 27 drives the actuating member 36 to move upwards through the driving rod 29, the valve handle 38 is driven to rotate reversely through the cooperation of the yielding groove 3601 and the switching column 39, so that the air inlet end of the induced draft fan 5 is switched from being communicated with the second air suction pipe 11 to being re-communicated with the first air suction pipe 7, and meanwhile, the actuating member 36 drives the sealing plate 41 to move upwards through the opening and closing member 40, so that the air inlet 12 is re-opened.
As a still further scheme of the invention, a normally closed valve group No. two is further arranged on the outer wall of the box body 2, and the valve group No. two is communicated with the clean room through an air supplementing pipe 55;

A transmission structure is further arranged between the second valve group and the executing piece 36, the transmission structure drives the valve handle 38 to reversely rotate by the executing piece 36, so that the second valve group is closed in the process of switching the air inlet end of the induced draft fan 5 from being communicated with the second air suction pipe 11 to being re-communicated with the first air suction pipe 7, and the clean room is isolated from the ambient atmosphere.
In the embodiment, the second valve group is kept in a closed state under a normal operation state of the device, when the negative pressure in the air ash chamber is continuously increased to exceed the negative pressure in the clean chamber and reach the moment that dust attached to the filter holes and the filter element can be stripped, dust particles blocked in the filter element and the filter holes are flushed to the bottom of the ash bucket 3 by reverse air flow generated by pressure difference, the clean chamber and the air ash chamber are smoothly conducted again, the pressure difference between the clean chamber and the air ash chamber is instantaneously eliminated, in the process, the second valve group is opened through the flicking component, the clean chamber is conducted with the ambient atmosphere, and the clean chamber with the internal negative pressure state is sucked from the external environment and is conducted into the air ash chamber, so that the clean chamber and the air ash chamber are restored to a normal pressure state.
In the process that the pressure in the clean room is restored to normal pressure from negative pressure, the buffer spring 17 drives the sliding cake 15 and the telescopic rod 14 to move rightwards to the initial position by means of the elasticity of the buffer spring, the telescopic rod 14 drives the push-pull frame 19 and the transverse moving frame 31 to move rightmost ends respectively, correspondingly, the clamping column 33 moves to the right lower inflection point position of the track groove 3401, the convex column 2202 rises to the highest stroke point, the section of the power accumulating spring 28 below releases the elasticity to drive the control rod 27 to bounce upwards, finally the actuating piece 36 is driven to rise, the actuating piece 36 rises to switch the valve group I to the initial state, and meanwhile, the valve group II is closed by the transmission structure.

In this embodiment, when the negative pressure value in the ash chamber exceeds the negative pressure in the clean chamber and reaches the moment of dust stripping, the pressure difference between the clean chamber and the ash chamber is instantaneously eliminated because dust particles are washed toward the bottom of the ash bucket 3, and at this moment, the pressure in the clean chamber and the ash chamber fluctuates, specifically, the negative pressure in the ash chamber is reduced, and the negative pressure in the clean chamber is increased;
and because the spring assembly is communicated with the ash chamber, the second valve group is opened through the spring assembly by utilizing the fluctuation of the pressure in the ash chamber at the moment.
After the second valve group is opened, the clean room is communicated with the ambient atmosphere, so that the pressure in the clean room and the air ash chamber can be gradually restored to normal pressure, and at the moment of restoring to normal pressure, the control rod 27 drives the executing piece 36 to rise through the driving rod 29, and the second valve group is closed through the transmission structure.
As a still further aspect of the present invention, the bouncing component includes a pressure regulating pipe 42 horizontally disposed on the outer wall of the case 2, and one end of the pressure regulating pipe 42 is communicated with the interior of the ash chamber through a conduit 44;

At an instant when the pressure difference between the clean room and the ash chamber is instantaneously eliminated, the negative pressure in the ash chamber is reduced to fluctuate, and the sliding cap and the movable rod 43 are separated from the guide pipe 44 by a certain distance due to the elasticity of the balance spring 46;
