Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, and in particular to a dust removal equipment for paper product manufacturing. Background Technology

[0002] Dust removal devices for paper product manufacturing are specialized environmental protection and production safety equipment designed for paper product processing production lines. They are mainly used to collect, filter, separate, and purify the gas containing paper scraps generated during the operation of equipment in paper product manufacturing processes such as cutting, printing, die-cutting, folding, and binding. These devices typically rely on the negative pressure generated by a fan to draw lightweight paper scraps and dust floating in the production area into the equipment. Through structures such as filter screens, filter elements, cyclone separators, bag filters, or electrostatic adsorption, solid paper scraps in the gas are intercepted, achieving separation of gas and paper scraps. The purified gas is then discharged in compliance with standards or returned to the workshop, thereby improving the production environment, preventing paper scraps from affecting equipment precision, product quality, and the working environment of operators, while also reducing the safety hazards caused by dust accumulation.

[0003] In current technologies, most dust removal devices conventionally used in paper product manufacturing only have simple filtration and collection functions. They can only roughly intercept larger paper particles and have limited effectiveness in capturing fine paper dust and lightweight flocculent paper particles. They are unable to achieve sufficient, stable, and effective treatment of paper particles in the gas. Moreover, these devices generally only have collection and storage functions and lack structural designs for squeezing and compacting the collected paper particles. This results in loose accumulation of paper particles, occupying a large space, and requiring frequent cleaning. They cannot simultaneously compact and reduce the volume of paper particles during the processing, leading to problems such as insufficient processing efficiency and troublesome subsequent cleaning in actual use.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] Example 1, as Figure 1 , Figure 2 and Figure 3As shown, a dust removal device for paper product production includes a housing 1, a cover plate 2 fixedly connected to the upper end of the housing 1, a protective plate 3 fixedly connected to the upper end of the cover plate 2, a motor 4 fixedly connected to the top wall of the protective plate 3, an installation groove provided on the lower rear side of the outer surface of the housing 1, a baffle 5 slidably connected to the inner surface of the installation groove, a drain pipe 6 fixedly connected to the lower front side of the outer surface of the housing 1 and communicating with its inner cavity, an air inlet pipe 7 fixedly connected to the upper left side of the outer surface of the housing 1 and communicating with its inner cavity, a U-shaped water storage box 8 fixedly connected to the upper part of the outer surface of the housing 1, a dust removal component 9 fixedly installed on the upper part of the inner surface of the housing 1, and an exhaust component 10 fixedly installed on the lower part of the inner surface of the housing 1.

[0032] In the process of using this solution, the air inlet pipe 7 can be fixedly connected to the conveying pipe in the prior art. Then the conveying pipe will transport the waste gas in the paper product production device into the air inlet pipe 7. Then the waste gas will enter the inner cavity of the outer shell 1 through the air inlet pipe 7. At this time, the motor 4 is started, which drives the dust removal component 9 to run. During the operation of the dust removal component 9, it can humidify the waste gas entering the inner cavity of the outer shell 1 by cooperating with the U-shaped water storage box 8. This will cause the paper scraps in the waste gas to become damp and settle downwards. In this process, the dust removal component 9 can also scrape the damp paper scraps into the upper side of the exhaust component 10.

[0033] During use, the exhaust assembly 10 can continuously crush the damp paper scraps that fall onto its surface, causing them to fall to the bottom of the outer casing 1 and accumulate. The accumulated paper scraps are then continuously squeezed by the exhaust assembly 10, compacting them and squeezing out the moisture. The squeezed-out moisture is discharged through the drain pipe 6, while the exhaust gas is discharged from the exhaust assembly 10. Finally, by pulling the baffle 5, the baffle 5 is removed from the mounting groove on the lower rear side of the outer surface of the outer casing 1, and the compacted paper scraps on the bottom wall of the outer casing 1 can be scraped out.

[0034] The conveying pipe and paper product production device mentioned above are conventional settings in the prior art. In this solution, it is only necessary to ensure that one end of the conveying pipe is fixedly connected to the exhaust end of the paper product production device, and then the other end of the conveying pipe is fixedly connected to the air inlet pipe 7, so that the exhaust gas and dust generated during the production of the paper product production device can enter the inner cavity of the outer shell 1 together. The specific installation method and shape characteristics can be adjusted according to the actual production needs, so this solution will not elaborate on them in detail.

[0035] Example 2, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, in this embodiment, a guide block 71 is fixedly connected to the front right side of the inner surface of the air intake pipe 7, and the guide block 71 is set in an inclined position.

[0036] Furthermore, the dust removal component 9 includes a main rod 91, which is rotatably connected to the lower middle part of the cover plate 2.

[0037] Furthermore, the water spray assembly 93 includes a hollow disc 931, the outer surface of which is fixedly connected to the upper part of the inner surface of the outer casing 1. A shaped material discharge groove 932 extending through the lower end of the upper right side of the hollow disc 931 is provided. Limiting grooves 933 are provided on the rear left side and the front right side of the inner surface of the hollow disc 931. A mounting hole 934 is provided in the middle of the upper end of the hollow disc 931. Several fixing holes 935 are arranged in a circular array on the upper end of the hollow disc 931. The inner surface is fixedly connected to a nozzle 936. The front middle of the outer surface and the rear middle of the outer surface of the hollow disc 931 are fixedly connected to L-shaped water inlet pipes 937. The two L-shaped water inlet pipes 937 are close to each other and penetrate through the outer surface of the hollow disc 931 and extend into its inner cavity. The two L-shaped water inlet pipes 937 are far apart and penetrate through the inner surface of the outer shell 1 and extend to the outer side. The upper part of the vertical part of the two L-shaped water inlet pipes 937 penetrates through the lower end of the U-shaped water storage box 8 and communicates with its inner cavity.

[0038] Furthermore, the extrusion assembly 94 includes a bidirectional lead screw 941, which is fixedly connected to the lower end of the main rod 91. The bidirectional lead screw 941 is located inside the mounting hole 934. A shaped airbag 942 is fixedly connected to the top wall of the hollow disc 931. A shaped extrusion plate 943 is threadedly connected to the outer surface of the bidirectional lead screw 941. Limiting blocks 944 are fixedly connected to the rear left side and the front right side of the outer surface of the shaped extrusion plate 943. The lower end of the shaped airbag 942 is fixedly connected to the upper end of the shaped extrusion plate 943. A base plate 945 is fixedly connected to the lower end of the hollow disc 931.

[0039] Furthermore, the ends of the two L-shaped water inlet pipes 937 that are close to each other are fixedly connected to the outer surface of the irregular airbag 942, the lower ends of several nozzles 936 are fixedly connected to the upper end of the irregular airbag 942, the irregular airbag 942 and the irregular extrusion plate 943 are matched with the shape of the inner surface of the hollow disc 931, and the two limiting blocks 944 are respectively slidably connected to the inner surface of the two limiting grooves 933.

[0040] Furthermore, the exhaust assembly 10 includes a secondary rod 101, which is fixedly connected to the lower end of a bidirectional lead screw 941. A fixing ring 102 is fixedly connected to the upper part of the outer surface of the secondary rod 101, and a bidirectional lead screw 103 is fixedly connected to the lower end of the secondary rod 101. Four inclined rods 104 are fixedly connected to the lower end of the fixing ring 102 in a ring array. A flow guide assembly 105 is rotatably installed on the upper part of the outer surface of the fixing ring 102. A pressing assembly 106 is threadedly installed on the outer surface of the bidirectional lead screw 103. Limiting rods 107 are fixedly connected to the front side of the middle part of the bottom wall of the outer casing 1 and the rear side of the middle part of the bottom wall. An exhaust pipe 108 is fixedly connected to the lower right side of the outer surface of the outer casing 1, and the exhaust pipe 108 communicates with the inner cavity of the outer casing 1.

[0041] Furthermore, the flow guiding assembly 105 includes a conical flow guiding plate 1051, a cylinder 1052 is fixedly connected to the outer arc surface of the conical flow guiding plate 1051, four connecting blocks 1053 are fixedly connected to the upper part of the outer surface of the cylinder 1052 in a ring array, and a cylinder 2 1054 is fixedly connected to the ends of the four connecting blocks 1053 that are far apart from each other.

[0042] Furthermore, the pressing assembly 106 includes a pressing plate 1061, which is threaded to the outer surface of the bidirectional lead screw 103. A tapered groove 1062 is provided at the upper end of the pressing plate 1061. A rectangular groove 1063 is provided on the front side and the rear side of the middle part of the inner surface of the tapered groove 1062. A drainage groove 1064 is provided on the middle left side and the middle right side of the inner surface of the tapered groove 1062.

[0043] Furthermore, the two limiting rods 107 are slidably connected to the inner surfaces of the two rectangular grooves 1063 respectively, and the exhaust pipe 108 is located between the conical guide plate 1051 and the pressing plate 1061.

[0044] During use, the waste gas and dust generated by the paper product production device are first sent into the air inlet pipe 7 through the external conveying pipe. A guide block 71 is fixedly connected to the front right side of the inner surface of the air inlet pipe 7, and the guide block 71 is set at an inclination. Therefore, the gas entering the inner cavity of the air inlet pipe 7 will be guided by it, and at the same time, the gas will be blown towards the arc surface of the scraper 92. During this process, the motor 4 can be started, and the output end of the motor 4 will drive the main rod 91 fixedly connected to it to rotate through the coupling. When the main rod 91 rotates, since several scraper plates 92 are fixedly connected to the outer surface of the main rod 91, the several scraper plates 92 can continuously push the gas entering the upper part of the inner cavity of the outer shell 1.

[0045] Meanwhile, when the main rod 91 rotates, since the bidirectional lead screw 941 is fixedly connected to its lower end, and the shaped extrusion plate 943 is threadedly connected to the outer surface of the bidirectional lead screw 941, and the two limiting blocks 944 fixedly connected to the outer surface of the shaped extrusion plate 943 are respectively slidably connected to the two limiting grooves 933 opened on the inner surface of the hollow disk 931, when the bidirectional lead screw 941 rotates with the main rod 91, under the limiting and guiding action of the limiting grooves 933 and the limiting blocks 944 on both sides, the shaped extrusion plate 941 can rotate. The shaped extrusion plate 943 moves upward, and when the shaped extrusion plate 943 moves upward, the shaped extrusion plate 943 can squeeze the shaped airbag 942, and spray the water in the inner cavity of the shaped airbag 942 out from several nozzles 936. The sprayed water will enter between several scraping plates 92 and the inner wall of the outer shell 1, and then mix with the paper scraps in the exhaust gas. When the several scraping plates 92 rotate around the center point of the main rod 91, they can scrape the wet paper scraps onto the shaped discharge groove 932 opened at the upper end of the hollow disc 931.

[0046] As can be seen from the above, the irregularly shaped airbag 942 and the irregularly shaped extrusion plate 943 are both matched with the inner surface shape of the hollow disc 931, and the shape of the bottom plate 945 is matched with the shape of the hollow disc 931. Therefore, several scraping plates 92 can scrape the damp paper scraps from the irregularly shaped discharge groove 932 to the lower side of the inner cavity of the outer shell 1.

[0047] During the above operation, as the bidirectional lead screw 941 rotates, the irregular extrusion plate 943 can move up and down reciprocally. When the irregular extrusion plate 943 moves downward, the irregular airbag 942 can draw water from the inner cavity of the U-shaped water storage box 8 back into its inner cavity through the L-shaped water inlet pipes 937 on both sides for storage, so that the irregular airbag 942 can continuously spray water when it is squeezed later.

[0048] When damp paper scraps fall to the lower side of the inner cavity of the outer shell 1, they will fall onto the surface of the conical guide plate 1051. Since the fixing ring 102 is fixedly connected to the upper part of the outer surface of the auxiliary rod 101, and the upper end of the auxiliary rod 101 is fixedly connected to the lower end of the double-acting screw 941, the auxiliary rod 101 will rotate simultaneously with the double-acting screw 941. As the auxiliary rod 101 rotates, the fixing ring 102 drives the four inclined rods 104 fixedly connected to its lower end to slide continuously on the outer surface of the conical guide plate 1051. When the four inclined rods 104 rotate around the center point of the auxiliary rod 101, they can continuously grind the damp paper scraps that fall onto the surface of the conical guide plate 1051. The ground paper scraps will then flow downward along the gap between the first cylinder 1052 and the second cylinder 1054, and then flow to the bottom wall of the outer shell 1.

[0049] During the rotation of the auxiliary rod 101, since the bidirectional lead screw 103 is fixedly connected to its lower end, and the pressing plate 1061 is threadedly connected to the outer surface of the bidirectional lead screw 103 and the two limiting rods 107 fixedly connected to the bottom wall of the outer shell 1 are slidably connected to the inner surface of the rectangular groove 1063, when the bidirectional lead screw 103 rotates, under the limiting and guiding action of the limiting rods 107 on both sides, the pressing plate 1061 can move downwards and reciprocate. When the pressing plate 1061 moves downwards, since its lower end is set as a plane, it can squeeze out the damp paper scraps that fall to the bottom wall of the outer shell 1.

[0050] When the pressing plate 1061 moves, some liquid overflows from the drain trough 1064 into the conical groove 1062 at the upper end of the pressing plate 1061. Due to the shape of the conical groove 1062, when the pressing plate 1061 moves upward, the water flows downward along the inclined surface of the conical groove 1062 and then flows back from the drain trough 1064 to the bottom wall of the inner cavity of the outer casing 1. This process is repeated to gradually compact the damp paper scraps.

[0051] When the dust removal process is completed, an external air extraction mechanism can be connected to the exhaust pipe 108 to extract the gas after dust removal inside the outer shell 1. Then, the water in the lower part of the inner cavity of the outer shell 1 can be discharged by opening the drain pipe 6.

[0052] When it is necessary to remove the paper scraps from the bottom wall of the outer casing 1, the baffle 5 can be pulled out from the mounting groove opened on the lower rear side of the outer surface of the outer casing 1, and then the paper scraps on the bottom wall of the outer casing 1 can be scraped off.

[0053] The aforementioned air extraction mechanism is a conventional setup in the prior art. In this solution, it is only necessary to ensure that the exhaust pipes 108 are interconnected so as to extract the gas after dust removal from the inner cavity of the outer casing 1. The specific installation method, circuit connection method, and control method are all conventional designs and can be adjusted according to actual production needs. Therefore, this solution will not elaborate on them in detail.

[0054] It should be noted that the specific installation method of the motor 4, the circuit connection method, and the control method used in this invention are all conventional designs, and will not be described in detail here.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
