Description

Technical Field

[0001] This invention relates to the field of industrial dust removal technology, specifically to an industrial dust collector. Background Technology

[0002] There are many types of industrial dust collectors, including baghouse dust collectors. Baghouse dust collectors are dry filtration devices suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter cloth, as the dust is trapped.

[0003] Filter bag damage is one of the most common causes of damage to baghouse dust collectors. Because flue gas and other adsorbed gases contain various corrosive substances, it is necessary to adsorb the gas entering the dust collector to prevent toxic gases, corrosive gases, water vapor, and other harmful gases from entering and damaging the filter bags. Factories use adsorbents to adsorb harmful gases and prevent them from entering the dust collector. However, adsorbents have a limit to their use; when they reach their adsorption limit, they can no longer adsorb. If the adsorbent is not replaced in time, harmful gases will enter the dust collector, damaging the filter bags and rendering the dust collector unusable.

[0004] To address this, an industrial dust collector is proposed. The suction force of the dust collector drives a sliding plate to move, and the movement of the sliding plate switches the adsorption channel to achieve the effect of automatically replacing the adsorbent. Summary of the Invention

[0005] The purpose of this invention is to provide an industrial dust collector that uses the suction force of the dust collector to drive a sliding plate to move. The movement of the sliding plate switches the adsorption channel to achieve the effect of automatically replacing the adsorbent, preventing harmful gases from entering the dust collector and damaging it when the adsorbent becomes ineffective, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An industrial dust collector, comprising:

[0008] A filter box is provided with an air pump connected to one side of the filter box and an insulated box on the other side of the filter box. A connecting pipe is fixedly installed between the insulated box and the filter box. A gas sensor and a humidity sensor are installed inside the insulated box near the connecting pipe, and a dust suction pipe is fixedly installed on the side of the insulated box away from the connecting pipe.

[0009] The air pump operates, drawing dust-laden air from outside into the filter box through the connecting pipe and suction pipe, where the dust is filtered by the filter bags.

[0010] Also includes:

[0011] A replacement device is installed inside the insulated box, which contains an adsorption box. Multiple partitions are fixedly installed inside the adsorption box, dividing it into multiple adsorption channels. Adsorbent is placed in each adsorption channel. A locking mechanism is installed inside the insulated box. When the adsorbent in a channel becomes ineffective, the replacement device switches the adsorption channel where the adsorbent has failed. Simultaneously, the locking mechanism locks the replaced adsorption channel to prevent it from being opened while it is in operation.

[0012] When the gas sensor and humidity sensor detect that the content of harmful gases or water vapor in the air is too high, it indicates that the adsorption channel is not working properly and that the adsorbent inside has reached its limit. The gas sensor and humidity sensor are both connected to a control chip installed in the insulation box. The control chip activates a replacement device, which switches the adsorption channels, closing the adsorption channels that can no longer adsorb and opening new adsorption channels.

[0013] The replacement device includes sliding plates that slide and seal the two ends of the adsorption channel. Multiple filling frames arranged in a figure-eight shape are fixedly installed inside the adsorption channel. Connecting frames are provided at both ends of the adsorption channel. The connecting frames on both sides are fixedly installed to the multiple sliding plates on both sides. The connecting frames are connected to a pushing mechanism. The gas sensor and the humidity sensor detect the adsorbed gas and the humidity of the air. When the gas sensor and the humidity sensor detect that the humidity or harmful gas in the air reaches a set standard, the pushing mechanism pushes the sliding plates to move, thereby switching the adsorption channel.

[0014] The air pump draws air into the insulated box. Because the partition plate divides the adsorption box into multiple adsorption channels, the incoming air can be adsorbed through any adsorption channel before entering the connecting pipe. However, there are multiple sliding plates on both sides of the adsorption channels, which can block half of the adsorption channels. Air cannot enter the blocked adsorption channels and can only be adsorbed through the unblocked adsorption pipes. Because the adsorbent will become saturated after a long period of reaction, it can no longer adsorb. When the gas sensor and humidity sensor detect that the content of harmful gases or water vapor in the air is too high, they push the sliding plates to block the failed adsorption channels and open new adsorption channels, so that the adsorbent can be replaced in time. This ensures that the adsorption device can adsorb harmful gases entering the vacuum cleaner for a long time.

[0015] By placing the filling rack in an arrow or trumpet shape, the harmful gases entering the adsorption box can come into contact with the adsorbent placed inside the filling rack over a large area, thus improving the adsorption effect of the adsorption channel. Of course, the filling rack can also be used to replace the ineffective adsorbent, allowing the adsorption box to be used for a long time.

[0016] Of course, more adsorption channels can be set in the adsorption box. Only four channels are shown in this invention. There can be multiple adsorption boxes. An electric telescopic rod is installed at the bottom of the adsorption box. Multiple adsorption boxes are stacked up and down. When all the adsorption channels of the upper layer are used up, the electric telescopic rod pushes the new adsorption box into the designated position and pushes out the adsorption box that has been used up.

[0017] Preferably, the pushing mechanism includes connecting frames disposed at both ends of the adsorption channel. The connecting frames on both sides are respectively fixedly installed with a plurality of sliding plates on both sides. A pushing rod extending outside the insulation box is fixedly installed on each connecting frame, and the insulation box has a circular hole for the pushing rod to slide through. A pushing plate is fixedly installed between the pushing rods on both sides. A piston cylinder is provided on one side of the insulation box, and a support frame is fixedly installed on the piston cylinder to support it. The support frame is fixedly installed on the insulation box. A piston block is slidably connected inside the piston cylinder, and a piston rod extending outside the piston cylinder is fixedly installed at one end of the piston block. The piston rod is connected to the piston cylinder... The piston rod is slidably connected, with one end of the piston rod away from the piston block fixedly installed to the push plate. A compression spring abuts against the inner wall of the piston cylinder at the other end of the piston block. An air extraction pipe is fixedly installed between the piston cylinder and the connecting pipe. A first solenoid valve is installed on the air extraction pipe, and a vent pipe communicating with it is fixedly installed on the air extraction pipe. A second solenoid valve is installed on the vent pipe, and a third solenoid valve is installed on the connecting pipe. The first, second, and third solenoid valves are connected to a triggering component installed inside the insulation box. The triggering component controls the on / off state of the three solenoid valves by detecting the usage of the calcium chloride desiccant.

[0018] When the gas sensor and humidity sensor detect excessive levels of harmful gases or water vapor in the air, the installed control chip energizes the connected third solenoid valve. This energized valve blocks the air inlet of the connecting pipe, preventing dust from being drawn through the suction pipe and forcing air to be drawn through the extraction pipe on one side. Simultaneously, the first solenoid valve opens, drawing air from the piston cylinder through the extraction pipe. This causes the piston block to move to one side, moving the connected piston rod. The moving piston block compresses the compression spring, and the moving piston rod moves the connected push plate. The moving push plate then moves the push rods connected to both sides. The moving push rod drives the sliding plate fixed on the connecting frame to move, replacing the adsorption channel. After the first solenoid valve is energized for a period of time, it is de-energized, blocking the air extraction pipe. At this time, the third solenoid valve is de-energized, the connecting pipe is opened, and the dust extraction pipe can remove dust normally. When the adsorption channel needs to be replaced again, the second solenoid valve is energized, causing the air pipe to open, allowing outside air to enter the piston cylinder through the air pipe. This causes the compression spring inside the piston cylinder to push the piston plate back to its original position. The piston plate, back to its original position, pushes the push plate through the piston rod. The moving push plate, through the push rod and the connecting frame, drives the sliding plate to slide to the original adsorption channel.

[0019] The pushing mechanism also includes an electric telescopic rod disposed on one side of the insulation box. The movable end of the electric telescopic rod is fixedly installed with the pushing plate, and the support frame is fixedly installed with the fixed end of the electric telescopic rod. The electric telescopic rod is connected to the triggering component. The electric telescopic rod can push the pushing plate to move, and can push the sliding plate to move more precisely. It is suitable for use with multiple sets of adsorption pipes. However, the electric telescopic rod is expensive, consumes a lot of electricity, and is not environmentally friendly.

[0020] A corrugated pipe sleeved on the push rod is fixedly installed between the push plate and the outer wall of the insulation box.

[0021] Because the push rod needs to slide back and forth inside the insulation box, a round hole needs to be made in the insulation box. However, the push rod sliding in the round hole will create a gap, which will reduce the sealing of the insulation box and reduce the dust removal efficiency of the dust collector. Therefore, a corrugated pipe is used to cover the round hole so that external gas will not enter the insulation box through the gap between the push rod and the round hole.

[0022] Each of the adsorption channels is equipped with a sealing plate, and there are rotating blocks on both sides of the sealing plate to fix it. The rotating blocks are rotatably connected to the heat preservation box, and a sealing box is fixedly installed on the heat preservation box, with a sealing cover placed on the sealing box.

[0023] When the adsorbent in the filling rack needs to be refilled after the reaction is complete, remove the sealing cap from the sealing box, open the corresponding adsorption channel, find the corresponding adsorption channel, rotate the rotating block on it, remove the sealing plate above, place the new adsorbent into the filling rack, put the sealing plate back in its original position after filling, rotate the rotating block to fix the sealing plate, and then put the sealing cap back into the sealing box. Different sealing methods can make the sealing effect in the adsorption channel better.

[0024] The insulated box is equipped with a locking device connected to the partition plate, which prevents the adsorption channel from being opened while it is in operation.

[0025] Preferably, the locking component includes a sliding chamber formed inside the insulation box, a locking rod fixedly connected to the push rod inside the sliding chamber, the rotating shafts of the rotating blocks all extending into the sliding chamber, and a circular hole formed on the rotating shafts of the rotating blocks. A plurality of locking pins for limiting the rotation of the rotating blocks are fixedly installed on the locking rod. When the push rod pushes the sliding plate to open the corresponding adsorption channel, the locking pins move into the circular holes formed on the corresponding rotating shafts of the rotating blocks.

[0026] When the push rod moves, causing the sliding plate to move to one side, it blocks two of the adsorption channels. The moving push rod then moves the locking rod fixed thereon, causing multiple locking pins fixed thereon to move into the circular holes on the rotating block. At the same time, the locking pins that entered the circular holes on the rotating block are moved out, preventing the rotating pins above the normally operating adsorption channel from rotating and thus preventing the sealing plate from opening. Meanwhile, the rotating pins above the blocked adsorption channel can rotate normally. Through the cooperation between the locking pins and the holes on the circular shaft of the rotating block, the sealing plate on the adsorption channel cannot be opened during normal operation. This prevents operators from accidentally blocking the normally operating adsorption channel when they need to fill it, which could cause equipment failure or personal injury.

[0027] The locking mechanism also includes multiple electromagnets installed in the sliding chamber. One end of each electromagnet is provided with a fixed post. The insulation box is equipped with a trigger button that cooperates with the push plate. When the push rod moves and blocks two of the adsorption channels, the push rod drives the push plate to press against the trigger button, energizing the electromagnet. The electromagnet pushes the fixed post into the circular hole opened in the rotating block, preventing the corresponding rotating block from rotating. Of course, the electromagnet can quickly lock the rotating block. However, it requires electrical energy to control its movement and requires a corresponding electromagnet and trigger button, increasing the overall cost of the equipment.

[0028] The insulated box is equipped with an alarm device, and alarm buttons connected to the alarm device are installed on both inner walls of the sliding chamber. When the locking rod abuts against the alarm button on one side, the alarm device sends an alarm signal to prompt the operator to replace the adsorbent.

[0029] The alarm device includes a buzzer installed above each adsorption channel. When the locking lever slides to the other side, it pushes the alarm button to trigger it. The alarm button controls the corresponding buzzer to sound an alarm, notifying the operator to replace the adsorbent in time. The alarm device also includes an alarm light installed on the insulated box. By observing the alarm light, it can be determined which adsorption channel needs to be replaced with adsorbent. Of course, the two can also be combined to make the effect more obvious.

[0030] The rotating block has a fixed limit block installed on its rotating shaft, and the insulation box has a rotating groove for the limit block to rotate. When the rotating block is rotated to the closed position by the limit block and the rotating groove, the locking pin can enter the circular hole opened on the rotating shaft of the rotating block.

[0031] The rotating groove and the limiting block that slides within it allow the locking pin to be smoothly inserted into the circular hole on the rotating block's shaft after the rotating block is closed. It should be noted that the diameter of the circular hole is larger than the diameter of the locking pin, so that the locking pin can still enter the circular hole on the rotating block's shaft even if the rotating block deviates slightly.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] 1. The adsorption channel uses adsorbent placed inside to adsorb harmful gases entering the vacuum cleaner. The adsorbent in the adsorption channel continuously adsorbs harmful gases. When the gas sensor and humidity sensor detect that the content of harmful gases or water vapor in the air is too high, it indicates that the adsorbent in the adsorption channel being used has reached saturation. The sliding plates on both sides block the adsorption channel that has reached saturation, so that the adsorption channel for filling with new adsorbent is opened. By changing to different adsorption channels, the adsorbent can be quickly replaced, so that the adsorption device can continuously adsorb harmful gases entering the vacuum cleaner and prevent harmful gases from entering the vacuum cleaner and causing damage.

[0034] 2. The moving push rod will drive the locking rod fixed on it to move. The movement of the locking rod can drive the multiple locking pins fixed on it to move into the round holes opened on the rotating block. The locking pins cooperate with the holes on the round shaft of the rotating block, so that the sealing plate on the adsorption channel cannot be opened when the adsorption channel is working normally. This prevents the operator from accidentally blocking the normally working adsorption channel when filling, which could cause equipment failure or personal injury.

[0035] 3. The energized third solenoid valve blocks the air inlet of the connecting pipe, preventing it from suctioning through the vacuum hose and allowing air to be drawn in through the suction pipe on one side. At the same time, the first solenoid valve is energized and opens, drawing air from the piston cylinder through the suction pipe, causing the piston block to move to one side. The moving piston block drives the connected piston rod to move, and the moving piston block compresses the compression spring. The moving piston rod drives the connected push plate to move. Through multiple different solenoid valves, the suction force of the vacuum cleaner is converted into thrust to move the sliding plate. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0048] Example 1:

[0049] Please see Figure 1 When the air pump 2 operates, it draws dust-laden gas from the outside into the filter box 1 through the connecting pipe 3, the insulation box, and the suction pipe 5, and filters the dust through the filter bag inside the filter box 1.

[0050] When the ambient humidity of the industrial dust collector reaches the limit, the adsorbent should be replaced with silica gel desiccant to reduce the water vapor content in the air.

[0051] Please see Figure 6 , Figure 8In the first set of adsorption channels, the vacuum pump 2 draws the harmful gas into the insulated box 4. Because the partition plate 25 divides the adsorption box 23 into multiple adsorption channels, the harmful gas can enter the connecting pipe 3 through any channel. However, there are multiple sliding plates 22 on both sides of the adsorption channel, which causes half of the adsorption channel to be blocked. The harmful gas cannot enter the blocked adsorption channel for adsorption, so the harmful gas can only be adsorbed through the adsorption pipe that is not blocked.

[0052] Please see Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 When the gas sensor and humidity sensor detect excessive levels of harmful gases or water vapor in the air, the control chip controls the first solenoid valve 9, the second solenoid valve 91, and the third solenoid valve 92 to operate on and off. The control chip energizes the third solenoid valve 92, which blocks the air inlet of the connecting pipe 3, preventing it from suctioning through the suction pipe 5. Instead, air is drawn through the suction pipe 6 on one side. Simultaneously, the first solenoid valve 9 is energized and opens, drawing air from the piston cylinder 10 through the suction pipe 6, causing the piston block 17 to move to one side. The moving piston block 17 drives the connected piston rod 19 to move, and at the same time, the moving piston block 17 will squeeze the compression spring 18. The moving piston rod 19 drives the connected push plate 7 to move, and the moving push plate 7 drives the push rods 20 connected on both sides to move. The moving push rods 20 drive the sliding plate 22 fixed on the connecting frame 21 to move through the connecting frame 21, and replace the adsorption channel. After the first solenoid valve 9 is energized for a period of time, it is de-energized and the suction pipe 6 is blocked. At this time, the third solenoid valve 92 is de-energized, the connecting pipe 3 is opened, and the dust suction pipe 5 can remove dust normally.

[0053] It should be noted that the first solenoid valve 9 and the second solenoid valve 91 are initially closed, while the third solenoid valve 92 is initially open. When the dust collector is in normal use, the connecting pipe 3 will not draw air through the extraction pipe 6.

[0054] Please see Figure 2 , Figure 3When it is necessary to refill the silica gel desiccant in the filling rack 24 after the reaction is completed, remove the sealing cover 14 from the sealing box 13, open the corresponding adsorption channel by observing the alarm device, find the corresponding adsorption channel, rotate the rotating block 16 on it, remove the sealing plate 15 above, place the silica gel desiccant into the filling rack 24, put the sealing plate 15 back in its original position after filling, rotate the rotating block 16 to fix the sealing plate 15, and then place the sealing cover 14 into the sealing box 13. By using different sealing methods, the sealing degree in the adsorption channel is better, and the silica gel desiccant can be filled while the dust collector is working.

[0055] Please see Figure 6 , Figure 7 By placing the filling rack 24 in an arrow or trumpet shape, the humid air entering the adsorption box 23 can fully react with the calcium chloride desiccant placed in the filling rack 24, thus improving the adsorption effect of the adsorption channel. Of course, the filling rack 24 can also be used to refill the calcium chloride desiccant after the reaction is complete, so that the adsorption box can be used for a long time.

[0056] Please see Figure 4 , Figure 5 , Figure 8 The second set of adsorption channels is used when the calcium chloride desiccant in the replaced adsorption channel has completely reacted. The adsorption channel needs to be replaced again. The second solenoid valve 91 is energized, which causes the vent pipe 8 to open, allowing external air to enter the piston cylinder 10 through the vent pipe 8. This causes the compression spring 18 in the piston cylinder 10 to push the piston plate back to its original position. The piston plate, which has returned to its original position, pushes the push plate 7 to move through the piston rod 19. The moving push plate 7 drives the sliding plate 22 to slide back to the original adsorption channel through the push rod 20 and the connecting frame 21. By replacing the adsorbent in a timely manner, the adsorption device can continuously adsorb the moisture entering the vacuum cleaner.

[0057] Example 2:

[0058] When the harmful gas levels in the environment where the industrial dust collector is used reach the limit, the adsorbent is replaced with activated carbon adsorbent to prevent harmful substances in the air from entering the dust collector. The sealing cover 14 is removed from the sealing box 13. By observing the alarm device, the corresponding adsorption channel is opened. After finding the corresponding adsorption channel, the rotating block 16 on it is rotated to remove the upper sealing plate 15. The activated carbon adsorbent is placed into the filling rack 24. After filling, the sealing plate 15 is put back in its original position. The rotating block 16 is rotated to fix the sealing plate 15. Then the sealing cover 14 is placed back into the sealing box 13.

[0059] Example 3:

[0060] When the harmful gases and humidity in the environment where the industrial dust collector is used reach the limit, replace the adsorbent with activated carbon adsorbent and silica gel desiccant, remove the sealing cover 14 from the sealing box 13, open the corresponding adsorption channel by observing the alarm device, find the corresponding adsorption channel and rotate the rotating block 16 on it, remove the sealing plate 15 above, and place the activated carbon adsorbent and silica gel desiccant into different filling racks 24 respectively.

[0061] Of course, the adsorbent can be replaced according to the specific operating environment of the industrial dust collector.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
