Description

Technical Field

[0001] The invention belongs to the field of workshop dust removal, in particular to a workshop dust collector. Background Art

[0002] Dust is generated in many links of feed production, such as material crushing, mixing, screening, and packaging. When the dust mixes with air to a certain concentration and comes into contact with an open flame, it will cause an explosion. People who are in an environment with a lot of dust for a long time will affect their health. Dust falling into the equipment will also cause electrical equipment to fail and cause safety accidents. Therefore, a dust collector is needed to remove dust from the workshop to prevent dust explosions and protect the health of personnel.

[0003] Existing feed mills mostly use bag dust collectors. The bags are made of a series of fiber materials and have high filtration efficiency, wear resistance and high temperature resistance. When the dust-containing gas passes through the bags, the dust will be retained by the bags, while the clean gas will be discharged through the gaps in the bags.

[0004] After a lot of dust is trapped on the surface of the bag, the surface adsorption of the bag is saturated, and the filtering efficiency of the dust-containing gas is reduced. Therefore, the back-blowing method is usually used to clean the dust on the surface of the bag online, which is a poor cleaning method.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. A workshop dust collector described in the present invention divides the space in the machine body into a filtering space and a cleaning space by setting a sealing component. The two spaces do not interfere with each other when they are not connected. The dust on the surface of the bag can be backblown in the cleaning space to clean the bag.

[0019] 2. The workshop dust collector described in the present invention has an air inlet, and the air enters the interior of the bag at an angle downward from the air inlet. Compared with the air entering the bag vertically downward, the oblique entry of air can produce rotation, which is more conducive to the removal of dust and the like from the bag. In conjunction with the rotating plate, the air contacts the rotating plate when it enters the interior of the bag at an angle, and pushes the rotating plate to rotate. The rotation of the rotating plate causes the bag to shake, and the shaking of the bag makes the cleaning effect of the bag better.

[0020] 3. The workshop dust collector described in the present invention is subject to the influence of factors such as long-term wear and tear and rat gnawing, and the bag is likely to be damaged. This will cause part of the dust-containing gas to enter the inside of the bag from the damaged part of the bag when the dust collector is in use, and be directly discharged from the No. 1 air outlet pipe. By setting up sensors, the damage of the bag can be detected so that timely maintenance can be carried out. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figure 1-Figure 11As shown, a workshop dust collector according to an embodiment of the present invention comprises a body 1 and a dust removal part 5, wherein a No. 1 air inlet pipe 3 is installed at the bottom of the body 1, a No. 1 air outlet pipe 4 is provided at the top of the body 1, an air pump is provided in the No. 1 air outlet pipe 4, and a No. 1 dust collecting plate 510 is installed at the bottom of the body 1, and is characterized in that the dust removal part 5 comprises: a No. 1 plate 52 fixedly installed inside the body 1; a plurality of bag assemblies, the bag assemblies comprise a No. 1 connecting plate 55, the No. 1 connecting plate 55 is rotatably installed on the No. 1 plate 52, a plurality of bag cages are provided on the No. 1 connecting plate 55, an air vent 537 is provided at the upper end of the bag cage, and a bag 51 is installed in the bag cage; a sealing assembly 57 arranged inside the body 1, the sealing assembly 57 divides the interior of the body 1 into two inner and outer circles, namely a filtering space 58 and a cleaning space 59, and one of the bag assemblies The cloth bags 51 of one bag cage are located in the cleaning space 59, and the cloth bags 51 of the other bag cages are all located in the filtering space 58. The sealing assembly 57 is used to isolate the filtering space 58 from the cleaning space 59. The sealing assembly 57 includes a number of No. 1 blocks 571 fixedly mounted on the No. 1 plate 52 and No. 2 blocks 572 rotatably mounted on the No. 1 blocks 571. The No. 2 blocks 572 are used to seal between two adjacent No. 1 blocks 571. The No. 2 blocks 572 adopt a telescopic mechanism; a partition plate 511 rotatably mounted on the No. 1 plate 52, and the partition plate 511 is used to isolate the No. 1 ash receiving plate 510 from the cleaning space 59; a No. 2 air inlet pipe 512 mounted on the body 1; and a filter plate 513 fixedly mounted on the No. 1 ash receiving plate 510. The gas enters the interior of the cloth bag 51 from the No. 2 air inlet pipe 512 and is discharged from the filter plate 513.

[0037] Specifically, after a lot of dust is trapped on the surface of the bag, the surface adsorption of the bag is saturated, and the filtering efficiency of the dust-containing gas is reduced. Therefore, the back-blowing method is usually adopted to clean the dust on the surface of the bag online, and this cleaning method is poor; multiple bags 51 in the same group are closely arranged, and the distance between two adjacent bags 51 in the same group is smaller than the outer diameter of the bag 51. In order to ensure that there is enough space for the bag 51 to pass through after the rotating part moves, the second block 572 is set to a telescopic structure; Initial State, several sealing components 57 are surrounded in a circle; the vacuum pump in the No. 1 air outlet pipe 4 is controlled to start, and the dust-containing gas enters the filter space 58 from the No. 1 air inlet pipe 3, and the dust-containing gas passes through the cloth bag 51 in the filter space 58 and enters the No. 1 air outlet pipe 4 from the air vent 537 to be discharged. When the dust-containing gas passes through the cloth bag 51, dust and other particles are trapped on the outer surface of the cloth bag 51 by the cloth bag 51, and the clean gas passes through the inner surface of the cloth bag 51 and enters the No. 1 air outlet pipe 4 from the air vent 537 to be discharged, so as to realize the filtering work;

[0038] Take the bag assembly containing three bag cages as an example, two of which are located in the filter space 58 to filter dust-containing gas, and one bag cage is located in the cleaning space 59. When in use, the partition 511 is intermittently controlled to rotate upward until the partition 511 isolates the No. 1 ash receiving plate 510 and the cleaning space 59 to prevent the dust on the No. 1 ash receiving plate 510 from entering the filter space 58 from the cleaning space 59, and then the No. 2 block 572 of the sealing assembly 57 is controlled to shrink. While the No. 2 block 572 shrinks, the No. 2 block 572 is controlled to rotate counterclockwise relative to the No. 1 block 571 so that there is a gap between the two adjacent No. 1 blocks 571. At this time, the No. 1 connecting plate 55 is controlled to rotate. The rotation of the No. 1 connecting plate 55 causes the filter plate 513 on the No. 1 connecting plate 55 to rotate, and a bag 51 in the filter space 58 is rotated into the cleaning space 59, and the clean bag 51 in the cleaning space 59 is rotated into the filter space 58. After the rotation is completed, the sealing assembly is controlled. 57 isolates the filter space 58 and the cleaning space 59 again. At this time, the control partition 511 is rotated to the original state, so that the No. 1 dust collecting plate 510 is connected with the cleaning space 59, and then air is introduced into the No. 2 air inlet pipe 512. The air enters the interior of the cloth bag 51 from the No. 2 air inlet pipe 512 and is discharged from the gap of the cloth bag 51. During the discharge process, the dust and other particles on the cloth bag 51 can be blown away from the cloth bag 51 to the No. 1 dust collecting plate 510. The dust and the like are collected on the No. 1 dust collecting plate 510, and the air is discharged from the body 1 through the filter plate 513, that is, the cloth bag 51 is cleaned by backblowing; by setting up multiple groups of cloth bags 51, the cloth bag 51 can switch between the filter space 58 and the cleaning space 59. After the cloth bag 51 is cleaned in the cleaning space 59, it rotates to the filter space 58 for filtering and dust removal. During the rotation process, the sealing component 57 is temporarily opened to open each channel, and isolation is required at other times to achieve a better cleaning effect.

[0039] like Figure 2 , Figure 3 As shown, the dust removal part 5 further includes: a filter plate 513 on the first dust receiving plate 510 in an upwardly convex shape.

[0040] Specifically, by providing the raised filter plate 513 , particles such as dust that fall onto the dust collecting plate cannot completely block the gaps of the filter plate 513 , thereby ensuring that air can be discharged from the machine body 1 through the filter plate 513 .

[0041] like Figure 4 , Figure 5 As shown, the dust removal part 5 also includes a number of No. 3 plates 54 rotatably mounted on the No. 1 plate 52, a number of bag assemblies are distributed in a circular array on the No. 3 plate 54, and a telescopic rod 514 is fixedly mounted on the sealing assembly 57 between the two No. 1 connecting plates 55 of the same No. 3 plate 54, and the other end of the telescopic rod 514 is fixed to the inner wall of the body 1.

[0042] Specifically, the telescopic rod 514 is electrically controlled. In the initial state, the telescopic rod 514 is in an extended state. After the partition 511 rotates upward until the partition 511 isolates the No. 1 dust collecting plate 510 and the cleaning space 59, the No. 2 block 572 of the sealing assembly 57 is controlled to shrink. While the No. 2 block 572 shrinks, the No. 2 block 572 is controlled to rotate counterclockwise relative to the No. 1 block 571. Then, the telescopic rod 514 is controlled to shrink backward, driving the sealing assembly 57 to shrink backward synchronously, so that a gap is generated between the two No. 1 connecting plates 55 of the same No. 3 plate 54, so that the No. 1 connecting plate 55 can be driven to rotate when the No. 3 plate 54 rotates. By setting the rotating No. 3 plate 54 and the No. 1 connecting plates 55 distributed in a ring array on the No. 3 plate 54, as many cloth bags 51 as possible can be loaded into the filter space 58 to improve the working efficiency of the dust collector.

[0043] like Figure 7-Figure 9 As shown, a No. 2 plate 53 is fixedly installed on the machine body 1, the cloth bag assembly also includes a No. 2 connecting plate 56 fixedly installed on the No. 2 plate 53, the bag cage also includes a ring 518 fixedly installed on the No. 2 connecting plate 56, the upper end of the cloth bag 51 is slidably connected to the ring 518, a plurality of round rods 519 are slidably installed on the ring 518 and the cloth bag 51, a protrusion 520 is fixedly installed on the round rod 519, and the round rod 519 limits the sliding of the upper end of the cloth bag 51 through the protrusion 520, a plurality of connecting rods 521 are fixedly installed inside the cloth bag 51, a long rod 522 is fixedly installed between the No. 1 connecting plate 55 and the No. 2 connecting plate 56, a slip ring 523 is slidably installed on the long rod 522, a rotating plate 524 is installed between the slip ring 523 and the connecting rod 521, and the two ends of the rotating plate 524 are rotatably connected to the connecting rod 521 and the slip ring 523 respectively, and a No. 1 spring 529 is installed between the upper end of the cloth bag 51 and the ring 518.

[0044] Specifically, after the cloth bag 51 enters the cleaning space 59, the round rod 519 on the cloth bag 51 is controlled to move downward, and the round rod 519 drives the protrusion 520 to move downward synchronously. Without the restriction of the protrusion 520, the upper end of the cloth bag 51 can move downward relative to the circular ring 518, and the cloth bag 51 moves to adapt to the shaking of the cloth bag 51 concave inward, so as to prevent the cloth bag 51 from being deformed or damaged due to the increase in tension; the slip ring 523 is controlled to move reciprocatingly up and down, and the movement of the slip ring 523 causes the rotating plate 524 to rotate. The rotation of the rotating plate 524 causes the connecting rod 521 to move radially back and forth in the direction close to the center of the cloth bag 51, and the movement of the connecting rod 521 causes the cloth bag 51 to shake, so that the dust particles on the cloth bag 51 fall off from the outer surface of the cloth bag 51.

[0045] like Figure 7-Figure 9As shown, the dust removal part 5 also includes: a rotating plate 525 rotatably installed on the long rod 522, a slide groove 526 is opened on the rotating plate 525, the slip ring 523 is slidably connected with the slide groove 526, and the rotating plate 525 rotates through the slide groove 526 to drive the slip ring 523 to move back and forth up and down; a plurality of wind shield plates 527 fixedly installed on the second plate 53; an air inlet 528 opened on the circular ring 518, and air enters the interior of the cloth bag 51 from the air inlet 528. After the air enters the interior of the cloth bag 51, it blows the rotating plate 525 to rotate.

[0046] Specifically, after the cloth bag 51 is transferred into the cleaning space 59, the No. 2 air inlet pipe 512 blows air toward the air inlet 528 of the ring 518, and the air obliquely enters the interior of the cloth bag 51 from the air inlet 528 downward, and the air contacts the rotating plate 525 and pushes the rotating plate 525 to rotate. The rotation of the rotating plate 525 causes the slip ring 523 to move up and down to realize the shaking of the cloth bag 51. Compared with the air entering the cloth bag 51 vertically downward, the oblique entry of air can produce rotation, which is more conducive to the removal of dust and the like from the cloth bag 51.

[0047] like Figure 5 , Fig. 9 As shown, the round rod 519 passes through the circular ring 518 , a No. 2 spring is installed between the protrusion 520 and the circular ring 518 , and a plurality of through holes 530 are opened on the No. 2 plate 53 .

[0048] Specifically, by setting the through hole 530, the round rod 519 is in contact with the air in both the filtering space 58 and the cleaning space 59. In the filtering space 58, the suction pump draws the gas upward, so that the round rod 519 moves upward synchronously. The movement of the round rod 519 drives the protrusion 520 to move upward to limit the movement of the upper end of the cloth bag 51. In the cleaning space 59, the gas blows the round rod 519 downward. The downward movement of the round rod 519 drives the protrusion 520 to move downward synchronously, so that the upper end of the cloth bag 51 can move up and down.

[0049] like Figure 2 , Figure 7 As shown, the dust removal part 5 also includes: a main gear 515 fixedly mounted on the body 1; a sub-gear 516 fixedly mounted on the second connecting plate 56, the main gear 515 and the sub-gear 516 are meshingly connected; a round shell 517 rotatably mounted on the second connecting plate 56, the round shell 517 is slidably connected to the second plate 53.

[0050] Specifically, when the No. 3 plate 54 rotates, it drives the No. 1 connecting plate 55 and the No. 2 connecting plate 56 to rotate synchronously. The rotation of the No. 2 connecting plate 56 drives the sub-gear 516 to rotate. When the No. 2 connecting plate 56 rotates close to the sealing assembly 57, the sub-gear 516 contacts the main gear 515. Since the main gear 515 is stationary, the sub-gear 516 rotates. The rotation of the sub-gear 516 drives the No. 2 connecting block and the No. 1 connecting block to rotate synchronously. The rotation of the No. 2 connecting block and the No. 1 connecting block causes the cloth bags 51 on the No. 2 connecting block and the No. 1 connecting block to rotate around the axis of the No. 2 connecting block, thereby realizing the position conversion of the cloth bags 51 on the No. 2 connecting block and the No. 1 connecting block, to ensure that each cloth bag 51 can be rotated into the cleaning space 59 for cleaning.

[0051] like Fig. 9 As shown, it also includes: a No. 1 rack plate 531 slidably installed on the ring 518, and a sensor 532 is fixedly installed below the No. 1 rack plate 531; a No. 1 gear 533 rotatably installed in the ring 518, and the No. 1 gear 533 is used to drive the No. 1 rack plate 531 to slide up and down; a No. 2 rack plate 534 is used to drive the No. 1 gear 533 to rotate, and the No. 2 rack plate 534 slides up and down with the ring 518.

[0052] Specifically, affected by factors such as long-term wear and tear and mouse gnawing, the cloth bag 51 may be damaged, which will cause part of the dust-containing gas to enter the cloth bag 51 from the damaged part of the cloth bag 51 when the dust collector is in use, and be directly discharged from the No. 1 air outlet pipe 4; the sensor 532 uses a pressure sensor 532. When the dust collector is in a non-working state, the upper end of the cloth bag 51 is not in contact with the protrusion 520, and there is a distance between the upper end of the cloth bag 51 and the sensor 532. When the dust collector is in a working state, the cloth bag 51 located in the filter space 58 is sucked by the suction pump, and the air pressure inside the cloth bag 51 is less than the air pressure around the cloth bag 51. Therefore, the cloth bag 51 is partially recessed inward. At this time, the upper end of the cloth bag 51 moves down to contact with the protrusion 520, and the upper end of the cloth bag 51 is not in contact with the sensor 532, and the No. 1 spring 529 is in a compressed state; when the cloth bag 51 is damaged, the air pressure inside the cloth bag 51 and the air pressure around the cloth bag 51 are When the pressure difference decreases, the upper end of the cloth bag 51 can move up under the action of the elastic force of the No. 1 spring 529 and contact the sensor 532. The sensor 532 is triggered by the pressure and can transmit a signal to the staff so that the staff can repair it in time. When the cloth bag 51 is located in the cleaning space 59, it is blown by the gas and the No. 2 rack plate 534 moves downward. The No. 2 rack plate 534 drives the No. 1 rack plate 531 and the sensor 532 to move upward through the No. 1 gear 533, so that the sensor 532 moves out of the moving range of the upper end of the cloth bag 51, avoiding the situation that the upper end of the cloth bag 51 moves up and down due to the shaking of the cloth bag 51 and frequently contacts the pressure sensor 532. When the cloth bag 51 is transferred to the filtering space 58, it is sucked and the No. 2 rack plate 534 moves upward. The No. 2 rack plate 534 drives the No. 1 rack plate 531 and the sensor 532 to move downward through the No. 1 gear 533, so that the sensor 532 moves into the moving range of the upper end of the cloth bag 51.

[0053] like Figure 3 , Figure 5 As shown, it also includes: a special-shaped hole 535 opened on the first plate 52; a second ash receiving plate 536 installed below the first plate 52, and the size of the second ash receiving plate 536 is smaller than the first ash receiving plate 510.

[0054] Specifically, by providing the second ash receiving plate 536 , when there are larger particles in the air entering from the first air inlet duct 3 , the particles can fall onto the second ash receiving plate 536 .

[0055] like Figure 5 As shown, the first connecting plate 55 is in a cone shape, and the cone angle of the cone faces upward.

[0056] Specifically, by providing the conical No. 1 connecting plate 55 , dust and the like can be prevented from gathering on the No. 1 connecting plate 55 .

[0057] Working steps:

[0058] Step 1, initial state, several sealing components 57 form a circle; control the vacuum pump in the No. 1 air outlet pipe 4 to start, the dust-containing gas enters the filter space 58 from the No. 1 air inlet pipe 3, the dust-containing gas passes through the cloth bag 51 in the filter space 58 and enters the No. 1 air outlet pipe 4 from the vent 537 to be discharged, when the dust-containing gas passes through the cloth bag 51, the dust and other particles are trapped on the outer surface of the cloth bag 51, and the clean gas passes through the inner surface of the cloth bag 51 from the vent 537 to be discharged from the No. 1 air outlet pipe 4, so as to realize the filtering work;

[0059] Step 2, after the dust collector has been used for a period of time, first control the partition 511 to rotate upward until the partition 511 isolates the No. 1 dust collecting plate 510 and the cleaning space 59, then control the No. 2 block 572 of the sealing assembly 57 to shrink, and control the No. 2 block 572 to rotate counterclockwise relative to the No. 1 block 571 while the No. 2 block 572 shrinks, so that there is a gap between the two adjacent No. 1 blocks 571, control the telescopic rod 514 to shrink backward, drive the sealing assembly 57 to shrink backward synchronously, so that a gap is generated between the two No. 1 connecting plates 55 of the same No. 3 plate 54, so that the No. 1 connecting plate 55 can be driven to rotate when the No. 3 plate 54 rotates, and control the No. 3 plate 54 to rotate so that the No. 1 connecting plate 55 and the No. 2 connecting plate 55 can be connected. The plate 56 rotates synchronously, and the rotation of the No. 2 connecting plate 56 drives the secondary gear 516 to rotate. When the No. 2 connecting plate 56 rotates to be close to the sealing assembly 57, the secondary gear 516 contacts the main gear 515. Since the main gear 515 is stationary, the secondary gear 516 rotates. The rotation of the secondary gear 516 drives the No. 2 connecting block and the No. 1 connecting block to rotate synchronously. The rotation of the No. 2 connecting block and the No. 1 connecting block causes the cloth bags 51 on the No. 2 connecting block and the No. 1 connecting block to rotate around the axis of the No. 2 connecting block, realizing the position conversion of the cloth bags 51 on the No. 2 connecting block and the No. 1 connecting block, and rotating a filter plate 513 in the filter space 58 into the cleaning space 59, and the clean cloth bag 51 in the cleaning space 59 rotates into the filter space 58;

[0060] Step 3: Control the sealing assembly 57 to isolate the filtering space 58 and the cleaning space 59 again, control the partition 511 to rotate to the original state, so that the No. 1 dust collecting plate 510 is connected with the cleaning space 59, and the No. 2 air inlet pipe 512 blows air to the air inlet 528 of the ring 518, and the air flies downward from the air inlet 528 into the interior of the cloth bag 51, and the air contacts the rotating plate 525 and drives the rotating plate 525 to rotate, and the rotating plate 525 rotates to make the slip ring 523 move up and down. 3 moves so that the rotating plate 524 rotates, and the rotation of the rotating plate 524 causes the connecting rod 521 to reciprocate radially toward the center of the cloth bag 51. The movement of the connecting rod 521 causes the cloth bag 51 to vibrate, and air is discharged from the gap of the cloth bag 51. During the discharge process, dust and other particles on the cloth bag 51 can be blown away from the cloth bag 51 to the filter plate 513, and the dust and other particles are collected on the filter plate 513, and the air passes through the filter plate 513 and is discharged into the machine body 1, thereby realizing the action of cleaning the cloth bag 51.
