Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, and in particular relates to a dust removal and purification device for printing equipment workshops. Background Technology

[0002] A printing press is the primary equipment for printing text and images. It typically consists of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). Modern printing presses can be categorized based on the type of printing plate used, such as letterpress printing presses, offset printing presses, gravure printing presses, screen printing presses, and specialty printing presses. Printing workshops generate significant amounts of dust and harmful gases during production. These pollutants not only affect print quality and the normal operation of equipment but also pose health risks to workshop workers.

[0003] An existing patent (publication number: CN208075174U) discloses a dust removal and purification device for a printing workshop, including a housing, a power storage device, and a motor. The top of the housing is provided with a top cover, and a first air inlet is provided below the top cover. A dust collection trough is installed on the right side of the first air inlet. The right end of the filter screen is connected to a deodorizing box. The lower end of the first air outlet is connected to a second air inlet. A blower is fixed below the fixed sleeve. The power storage device is located below the blower, and a water tank is provided below the power storage device. A pressure pump is installed inside the water tank, and the motor is located below the water tank.

[0004] Currently, traditional dust removal and purification devices have many shortcomings, such as poor dust removal effect, inconvenient maintenance, dust accumulation inside existing devices, time-consuming and labor-intensive cleaning and maintenance, and inability to effectively collect and purify pollutants, which may lead to poor dust removal effect inside the printing equipment workshop. Therefore, a dust removal and purification device for printing equipment workshops is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a dust removal and purification device for printing equipment workshops. This device has the advantages of enabling multi-stage filtration and purification of dust and harmful gases, thereby improving the collection and purification effect of dust and harmful gases. It solves the problems mentioned in the aforementioned prior art, such as time-consuming and labor-intensive cleaning and maintenance work, and the inability to effectively collect and purify pollutants, which may lead to poor dust removal effects inside the printing equipment workshop.

[0006] To achieve the above objectives, this application provides the following technical solution: a dust removal and purification device for a printing equipment workshop, comprising a dust removal box, a dust collection component inserted into the top of the dust removal box, a sliding mechanism provided on the outer surface of the dust collection component, a first filter device provided inside the dust removal box, an adsorption dust removal device provided at the bottom of the first filter device, a first dust collection box provided at the bottom of the adsorption dust removal device, a suction device connected to one side of the adsorption dust removal device, a photocatalytic purification box connected to the output end of the suction device, a second dust collection box provided at the bottom of the photocatalytic purification box, a driving device provided on the outer surface of the dust removal box, the output end of the driving device extending into the interior of the first filter device, and the dust collection component comprising a suction pipe, one end of which is fixedly connected to a dust collection hood.

[0007] The above solution connects the output end of the suction pipe in the dust collection assembly to the first filter device. When dust in the printing equipment needs to be absorbed, a sliding mechanism is installed near the paper feeding channel or printing roller of the printing equipment. The suction device generates suction force so that the dust can be initially filtered by the first filter device and then further adsorbed and purified by the adsorption dust removal device. Finally, the dust is pumped into the photocatalytic purification box for final purification. This multi-stage filtration and purification process improves the collection and purification effect of dust and harmful gases.

[0008] Furthermore, the sliding mechanism includes an electric slide rail, with mounting plates fixedly connected to both ends of the electric slide rail. A slide block is slidably connected to the inner wall of the electric slide rail, and a sleeve is fixedly connected to the bottom of the slide block. The dust suction pipe is sleeved inside the sleeve.

[0009] The above solution involves mounting the mounting plate on the printing equipment. When the electric slide rail is activated, its drive slide moves the sleeve below the electric slide rail, thereby providing displacement driving force for the dust suction pipe. This allows the dust suction pipe to move laterally in the dust suction position, fully absorbing the dust and gas generated during the printing process.

[0010] Furthermore, the first filtration device includes a first filter box, inside which a filter element is disposed, and a rod is inserted into the filter element, one end of which is threadedly connected to the output end of the drive device.

[0011] By connecting the output end of the drive device to the plug rod, when the drive device is started, the plug rod drives the filter element to rotate inside the first filter box, so that the dust entering the box can fully contact the dust suction gaps on the inside of the filter element, and can fully adsorb and filter fine dust.

[0012] Furthermore, the driving device includes a drive motor, an output shaft is fixedly mounted on the output end of the drive motor, a gear is fixedly mounted on the output end of the output shaft, and the output end of the gear is threadedly connected to the insertion rod.

[0013] With the above solution, when the drive motor is started, its drive output shaft drives the gear to rotate to provide rotational driving force for the insert rod, so that the insert rod can drive the filter element to rotate at a constant speed, thereby allowing the dust to fully contact each side of the filter element and improving the adsorption and filtration effect of the filter element.

[0014] Furthermore, the adsorption dust removal device includes an adsorption box, the inner wall of which is provided with an activated carbon adsorption layer, and an electrostatic generator is provided on the inner wall of the adsorption box, the electrostatic generator being located below the activated carbon adsorption layer.

[0015] With the above scheme, after the dust is initially filtered by the filter element, it continues to flow into the adsorption box, where the activated carbon adsorption layer continues to adsorb the dust and remove odors. At the same time, the electrostatic generator generates electrostatic dust removal. Through the dual action of the high-efficiency filter element and the electrostatic generator, fine dust in the workshop can be effectively removed.

[0016] Furthermore, the suction device includes a dust pump, the outer surface of which is connected to an input pipe and an output pipe, one end of which is connected to the adsorption box, and the output pipe is connected to the photocatalytic purification box.

[0017] The above solution involves installing a vacuum pump inside the dust collection box. When the vacuum pump is started, it generates a suction force to draw dust through the adsorption box and into the photocatalytic purification box. This provides a rapid flow driving force for dust transport, thereby improving the adsorption efficiency of dust and harmful gases. The photocatalytic purification box can effectively remove harmful gases and odors from the air.

[0018] Furthermore, a dustproof box is fixedly connected to the outer surface of the dust collection box, and the drive motor is located in the dustproof box.

[0019] The above solution provides dustproof installation and support for the drive motor through the dustproof box.

[0020] Furthermore, the filter elements are symmetrically arranged inside the first filter box.

[0021] The above solution, by placing the filter inside the first filter box and cooperating with two sets of gears to simultaneously provide driving force, increases the contact area with dust, thus achieving a better filtration effect.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This dust removal and purification device for printing equipment workshops connects the output end of the dust collection pipe in the dust collection component to a first filter device. When dust in the printing equipment needs to be absorbed, a sliding mechanism is installed near the paper feeding channel or printing roller of the printing equipment. The suction device generates suction force so that the dust can be initially filtered by the first filter device and then further adsorbed and purified by the adsorption dust removal device. Finally, the dust is further pumped into the interior of the photocatalytic purification box for final purification. This allows dust and harmful gases to undergo multi-stage filtration and purification, improving the collection and purification effect of dust and harmful gases. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 and Figure 2 This embodiment provides a dust removal and purification device for a printing equipment workshop, comprising a dust collection box 1, a dust collection assembly 2 inserted into the top of the dust collection box 1, a sliding mechanism 3 provided on the outer surface of the dust collection assembly 2, a first filter device 4 disposed inside the dust collection box 1, an adsorption dust removal device 5 disposed at the bottom of the first filter device 4, a first dust collection box 6 disposed at the bottom of the adsorption dust removal device 5, a suction device 7 connected to one side of the adsorption dust removal device 5, a photocatalytic purification box 8 connected to the output end of the suction device 7, a second dust collection box 9 disposed at the bottom of the photocatalytic purification box 8, a driving device 10 disposed on the outer surface of the dust collection box 1, the output end of the driving device 10 extending into the interior of the first filter device 4, and the dust collection assembly 2 including a suction pipe 20. 1. One end of the suction pipe 201 is fixedly connected to the suction hood 202. By connecting the output end of the suction pipe 201 in the suction assembly 2 to the first filter device 4, when it is necessary to absorb dust in the printing equipment, the sliding mechanism 3 is set up near the paper feeding channel or printing roller of the printing equipment. The suction device 7 generates suction force so that the dust can be initially filtered by the first filter device 4 and then further adsorbed and purified by the adsorption dust removal device 5. Finally, the dust is continued to be pumped into the photocatalytic purification box 8 by the suction device 7 for final purification treatment, so that dust and harmful gases can be purified through multi-stage filtration, thereby improving the collection and purification effect of dust and harmful gases.

[0032] Please see Figure 2 and Figure 3 The sliding mechanism 3 includes an electric slide rail 301, with mounting plates 302 fixedly connected to both ends of the electric slide rail 301. A slide block 303 is slidably connected to the inner wall of the electric slide rail 301, and a sleeve 304 is fixedly connected to the bottom of the slide block 303. The suction pipe 201 is sleeved inside the sleeve 304. By mounting the mounting plate 302 on the printing equipment, when the electric slide rail 301 is started, it drives the slide block 303 to move the sleeve 304 below the electric slide rail 301, thereby providing displacement driving force for the suction pipe 201. This allows the suction pipe 201 to drive the dust hood 202 to move laterally in the dust suction position, so as to fully absorb the dust and gas generated during the printing process.

[0033] Please see Figure 4The first filtration device 4 includes a first filter box 401, inside which a filter element 402 is disposed. A rod 403 is inserted into the filter element 402. One end of the rod 403 is threadedly connected to the output end of the drive device 10. The drive device 10 includes a drive motor 1011. An output shaft 1012 is fixedly mounted on the output end of the drive motor 1011. A gear 1013 is fixedly mounted on the output end of the output shaft 1012. The output end of the gear 1013 is threadedly connected to the rod 403. By connecting the output end of the drive device 10 to the rod 403, the drive device is activated. At 10 o'clock, the drive rod 403 drives the filter element 402 to rotate inside the first filter box 401, so that the dust entering the box can fully contact the dust suction gaps on the inner side of the filter element 402, and can fully adsorb and filter fine dust. When the drive motor 1011 is started, its drive output shaft 1012 drives the gear 1013 to rotate, providing rotational driving force for the drive rod 403, so that the drive rod 403 can drive the filter element 402 to rotate at a uniform speed, thereby allowing the dust to fully contact each side of the filter element 402, improving the adsorption and filtration effect of the filter element 402.

[0034] Please see Figure 4 and Figure 5 The adsorption dust removal device 5 includes an adsorption box 501, with an activated carbon adsorption layer 502 on the inner wall of the adsorption box 501. An electrostatic generator 503 is also located on the inner wall of the adsorption box 501, below the activated carbon adsorption layer 502. The suction device 7 includes a dust pump 701, with an input pipe 702 and an output pipe 703 connected to its outer surface. One end of the input pipe 702 is connected to the adsorption box 501, and the output pipe 703 is connected to the photocatalytic purification box 8. After the dust is initially filtered by the filter element 402, it continues to flow into the adsorption box 501 and is adsorbed by the activated carbon. Layer 502 continues to adsorb dust and remove odors, while electrostatic generator 503 generates electrostatic dust removal. Through the dual action of high-efficiency filter core 402 and electrostatic generator 503, fine dust in the workshop can be effectively removed. By installing dust pump 701 inside dust collection box 1, when dust pump 701 is started, its internal suction can generate moving suction to continue to pump dust through the inside of adsorption box 501 to the inside of photocatalytic purification box 8, so as to provide a fast flow driving force for dust transportation, thereby improving the adsorption efficiency of dust and harmful gases. The photocatalytic purification box 8 can effectively remove harmful gases and odors in the air.

[0035] This embodiment provides a dust removal and purification device for a printing equipment workshop. By mounting the support plate 302 on the printing equipment and cooperating with the slide 303, it provides displacement driving force to the suction pipe 201, enabling the suction pipe 201 to drive the suction hood 202 to move laterally at the suction position, thus fully absorbing the dust and gases generated during the printing process. By installing the suction pump 701 inside the dust collection box 1, it provides rapid flow driving force for dust transportation, thereby improving the adsorption efficiency of harmful gases. The drive motor 1011, in cooperation with the gear 1013, provides rotational driving force to the insertion rod 403, allowing the insertion rod 403 to drive the filter element 402 to rotate at a uniform speed, ensuring that the dust can fully contact every surface of the filter element 402, improving dust adsorption efficiency. The high-efficiency filter element 402 enhances the adsorption and filtration effect. The activated carbon adsorption layer 502 further adsorbs dust and removes odors. At the same time, the electrostatic generator 503 generates electrostatic dust removal. Through the dual action of the high-efficiency filter element 402 and the electrostatic generator 503, fine dust in the workshop can be effectively removed. The first dust collection box 6 and the second dust collection box 9 are respectively a liquid collection tank and a dust collection box. This design facilitates centralized treatment of dust and wastewater and reduces maintenance workload. The suction pipe 201 is equipped with a sensor to monitor the dust concentration and harmful gas content in the workshop in real time. The controller automatically adjusts the operating parameters of the device according to the feedback signal. When the monitored concentration exceeds the set value, the alarm device automatically sounds an alarm, so as to achieve a better dust monitoring and dust removal effect.

[0036] It should be noted that...

[0037] The working principle of the above embodiments is as follows:

[0038] The mounting plate 302 is mounted on the printing equipment. When the electric slide rail 301 is started, its drive slide 303 drives the sleeve 304 to move below the electric slide rail 301. After the dust pump 701 is started, it can generate a moving suction force inside, which, together with the dust suction hood 202, moves and sucks up dust on the printing equipment, allowing the dust to enter the interior of the first filter box 401. By starting the drive motor 1011, the output shaft 1012 drives the two sets of gears 1013 to rotate, providing rotational driving force for the insertion rod 403. The insertion rod 403 drives the filter element 402 at a constant speed. The rotation ensures that the dust comes into full contact with every surface of the filter element 402 and is filtered. The filtered dust and harmful gases enter the interior of the adsorption box 501, where the activated carbon adsorption layer 502 continues to adsorb the dust and remove odors. At the same time, the electrostatic generator 503 generates electrostatic dust removal, and some of the dust is collected inside the first dust collection box 6. With the help of the dust pump 701, the adsorbed and purified dust is further pumped into the photocatalytic purification box 8, where the harmful gases are purified and odors are removed by the internal photocatalytic purifier. The purified dust falls into the interior of the second dust collection box 9.
