Description

Technical Field

[0001] This utility model relates to the field of polyurethane coating conveying technology, specifically to a polyurethane coating conveying pipeline with filtration function. Background Technology

[0002] In order to ensure the final coating quality of polyurethane coatings, impurities in the polyurethane coatings need to be removed in a timely manner during the transportation process.

[0003] Currently, the pipelines used for transporting polyurethane coatings are mainly composed of a straight circular pipe. Although this type of pipeline can transport polyurethane coatings, it is necessary to use an additional filtration mechanism to filter the polyurethane coatings after transport before they can be sprayed. Because the transport and filtration processes are not continuous, it is not convenient for the efficient transport and use of polyurethane coatings. At the same time, there is also the risk that impurities will clog the transport pipeline, preventing the polyurethane coatings from being transported normally. Utility Model Content

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a polyurethane coating conveying pipe with a filtering function, including a connecting pipe. A conveying pipe one is installed at the inlet of the connecting pipe, and a conveying pipe two is installed at the outlet of the connecting pipe. The connecting pipe has a U-shaped structure. Two filter screens are symmetrically installed on the connecting pipe. An alternating sealing mechanism is installed on the connecting pipe between the two filter screens. The alternating sealing mechanism includes a rack, a gear, a motor, a vertical plate, a linkage rod, and a sealing plate.

[0008] Furthermore, both the first and second conveying pipes are threadedly connected to the connecting pipe, and the connection points of the first and second conveying pipes with the connecting pipe are equipped with sealing components.

[0009] Furthermore, the filter screen and the connecting pipe are connected by screws, and the contact area between the filter screen and the connecting pipe is equipped with a sealing gasket.

[0010] Furthermore, the upright plate is bolted to one side of the connecting pipe, and the motor is mounted on the upper part of one side wall of the upright plate.

[0011] Furthermore, the gear is mounted on the power output shaft of the motor, and there are two racks, which mesh with the two sides of the gear respectively.

[0012] Furthermore, the linkage rod is welded to the bottom end of the rack, and the sealing plate is connected to the bottom end of the linkage rod.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This invention involves installing a U-shaped connecting pipe between conveying pipe one and conveying pipe two, and symmetrically installing two filter screens on the U-shaped connecting pipe. Simultaneously, an alternating sealing mechanism consisting of a rack, pinion, motor, vertical plate, linkage rod, and sealing plate is installed on the U-shaped connecting pipe.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1-2As shown, this embodiment of a polyurethane coating conveying pipe with a filtering function includes a connecting pipe 3. A conveying pipe 2 is installed at the inlet of the connecting pipe 3, and a conveying pipe 4 is installed at the outlet of the connecting pipe 3. The connecting pipe 3 has a U-shaped structure, and two filter screens 5 are symmetrically installed on the connecting pipe 3. An alternating sealing mechanism 1 is installed on the connecting pipe 3 between the two filter screens 5. The alternating sealing mechanism 1 includes a rack 101, a gear 102, a motor 103, a vertical plate 104, a linkage rod 105, and a sealing plate 106. During the conveying process, it utilizes the... The filter screen 5 can filter the polyurethane coating during the conveying process. When one filter screen 5 becomes clogged, the gear 102 is rotated by the motor 103. The rotation of the gear 102 will cause one rack 101 to move upward and the other rack 101 to move downward, so as to seal both sides of the filter screen 5 after the blockage on the connecting pipe 3. This makes it easy to disassemble and clean the clogged filter screen 5. The conveying channel at the unblocked filter screen 5 on the other side will be connected to the conveying pipe 2 and the conveying pipe 4 to achieve continuous filtration of the polyurethane coating.

[0023] like Figures 1-2 As shown, in this embodiment, both the first conveying pipe 2 and the second conveying pipe 4 are threadedly connected to the connecting pipe 3. The connection points between the first conveying pipe 2 and the second conveying pipe 4 and the connecting pipe 3 are equipped with sealing components. Both the first conveying pipe 2 and the second conveying pipe 4 are polyurethane coating conveying pipes commonly used in the prior art. The filter screen 5 is connected to the connecting pipe 3 by screws. The contact points between the filter screen 5 and the connecting pipe 3 are equipped with sealing gaskets. The filter screen 5 is the main component for filtering the polyurethane coating.

[0024] like Figures 1-2 As shown, in this embodiment, the upright plate 104 is bolted to one side of the connecting pipe 3. The motor 103 is installed on the upper part of one side wall of the upright plate 104. The upright plate 104 is mainly used to provide the mounting base for the motor 103. The motor 103 is mainly used to provide power for the rotation of the gear 102. The gear 102 is installed on the power output shaft of the motor 103. There are two racks 101, which mesh with the two sides of the gear 102 respectively. After the gear 102 rotates under the action of the motor 103, the two racks 101 on both sides will move up and down relative to each other. A linkage rod 105 is welded to the bottom of the rack 101. A sealing plate 106 is connected to the bottom of the linkage rod 105. While the rack 101 moves up and down, it will use the linkage rod 105 to realize the convenient lifting and lowering of the sealing plate 106. The sealing plate 106 is slidably sealed to the upper part of the connecting pipe 3. The sealing plate 106 has an I-shaped structure. The sealing plate 106 is mainly used to alternately seal the two channels on the connecting pipe 3.

[0025] The specific implementation process of this embodiment is as follows: When in use, firstly, the first conveying pipe 2 and the second conveying pipe 4 are installed on the polyurethane coating conveying pipeline respectively. Then, simply connect the alternating sealing mechanism 1 to the external power supply and control components to put the conveying pipeline into use. During the conveying process, the polyurethane coating can be filtered by the filter screen plate 5. When one filter screen plate 5 is blocked, the gear 102 is rotated under the action of the motor 103. After the gear 102 rotates, one rack 101 moves up and the other rack 101 moves down, so as to seal both sides of the filter screen plate 5 after the blockage on the connecting pipe 3, making it convenient to disassemble and clean the blocked filter screen plate 5. The conveying channel at the unblocked filter screen plate 5 on the other side will be connected to the first conveying pipe 2 and the second conveying pipe 4 to achieve continuous filtration of polyurethane coating.

[0026] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
