TECHNICAL FIELD

[0001] The utility model relates to the field of dry filter dust removal, especially to a dust removal structure of dry filter. BACKGROUND

[0002] Dry filter is an important component in refrigeration system and some other fluid treatment systems, which is usually composed of shell, filter screen, desiccant and other parts. The filter screen mainly plays a role in intercepting large particles to prevent them from entering the desiccant and causing pollution. However, with long-term operation, the intercepted impurities gradually accumulate on the filter screen and need to be treated regularly.

[0003] Chinese patent CN221182260U discloses a dry filter with anti-blocking structure, which includes a dry filter body, an inlet pipe at the left end of the dry filter body, an outlet pipe at the right end of the dry filter body, and a fixed box fixedly connected to the upper end of the dry filter body. The cooperation with the spring can realize the horizontal shaking of the filter disc during the filtering process, preventing the impurities from blocking the filter disc and affecting the gas permeability.

[0004] The above-mentioned prior art has the following disadvantages: the device mainly uses the cooperation of the top block, the convex block and the spring to make the filter disc vibrate and prevent dust from adhering. However, in this way, dust usually accumulates in the end cover at the inlet end, so after long-term use, the end cover needs to be disassembled for cleaning dust. During the disassembly process of the end cover, the dry filter needs to be stopped, which affects the overall operation effect of the machine, so there is room for improvement.

Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the utility model.

[0023] Embodiment one

[0024] In order to solve the defect that the dust in the drying filter cannot be collected and removed separately in the prior art, the following scheme is disclosed, specifically as shown in Figures 1-4

[0025] A dust removal structure of a drying filter, comprising: a shell 1, one end of the shell 1 is communicated with an inlet pipe 2, the other end of the shell 1 is communicated with an outlet pipe 3, the inside of the shell 1 is filled with a drying agent 4, one end of the drying agent 4 close to the inlet pipe 2 is fixed with a first filter sheet 5, the other end of the drying agent 4 is fixed with a second filter sheet 6, the center of the first filter sheet 5 is penetrated by a rotating shaft 7, one end of the rotating shaft 7 close to the inlet pipe 2 is sleeved with a fixed sleeve 9, one side of the fixed sleeve 9 is fixed with a half-open scraping pipe 10, the opening side of the half-open scraping pipe 10 and the outer wall of the first filter sheet 5 abut, the inside of the half-open scraping pipe 10 movably sets a collecting mechanism 11, the collecting mechanism 11 comprises a clamping groove 115 opened at the bottom end of the inside of the half-open scraping pipe 10, the inside of the clamping groove 115 is rotatably connected with a rotating clamping ring 112, the inside of the rotating clamping ring 112 is fixed with an inner intercepting pipe 111, the top end of the inner intercepting pipe 111 extends to the outer wall of the half-open scraping pipe 10 and is sleeved with a bevel gear ring 113, the bottom end center of the first filter sheet 5 close to one side of the half-open scraping pipe 10 is fixed with an arc bevel gear plate 114, one end of the rotating shaft 7 close to the inlet pipe 2 is provided with a rotating assembly 8;

[0026] The opening arc of the half-open scraping pipe 10 is 160°, and the opening arc of the inner intercepting pipe 111 is 180°;

[0027] The moving path of the bevel gear ring 113 passes through the arc bevel gear plate 114, the bevel gear ring 113 and the arc bevel gear plate 114 are meshed with each other, and the bevel gear ring 113 rotates one circle under the meshing action of the arc bevel gear plate 114;

[0028] The rotating assembly 8 comprises a motor 81 fixed on the outside of the shell 1, the bottom end of the motor 81 is connected with a machine shaft 82, the bottom end of the machine shaft 82 extends to the inside of the shell 1 and is installed with a first bevel gear 83, the outer end of the rotating shaft 7 is fixed with a second bevel gear 84, the first bevel gear 83 and the second bevel gear 84 are meshed with each other.

[0029] ​In this embodiment, when the shell 1 runs for a period of time, the motor 81 is started, the shaft 82 drives the first bevel gear 83 to rotate, and the first bevel gear 83 and the second bevel gear 84 are meshed with each other, so that the rotating shaft 7 rotates, and the semi-open scraping pipe 10 rotates along the outer wall of the first filter piece 5. By using the scratching effect of the semi-open scraping pipe 10 during rotation, the dust attached to the outer surface of the first filter piece 5 is rolled into the inner cavity of the inner interception pipe 111. Since the inner cavity of the inner interception pipe 111 is in a columnar structure, the dust is collected and concentrated inside the inner interception pipe 111.

[0030] When the semi-open scraping pipe 10 approaches the bottom end, the bevel gear ring 113 and the arc-shaped bevel gear plate 114 come into contact and meshing, so that the inner interception pipe 111 rotates outward from the inside of the semi-open scraping pipe 10 under the rotation of the bevel gear ring 113. When the semi-open scraping pipe 10 moves to the bottom end, the inner interception pipe 111 and the semi-open scraping pipe 10 form a hollow columnar structure, so as to wrap the dust collected outside the first filter piece 5 to prevent the dust from overflowing outward.

[0031] Embodiment two

[0032] In order to further improve the collection effect of the dust in the shell 1, the collected dust is transferred to realize the subsequent non-stop cleaning effect. Therefore, the following scheme is disclosed, as shown in Figure 1 and Figure 5 as shown:

[0033] The transfer assembly 12 is arranged outside the shell 1 relative to the position of the rotating assembly 8, and the transfer assembly 12 is located directly below the arc-shaped bevel gear plate 114.

[0034] The transfer assembly 12 includes a transfer box 121 fixed outside the shell 1, and a connecting port 123 is communicated between the transfer box 121 and the shell 1. The connecting port 123 is provided with an electromagnetic valve 124 inside, and one side of the transfer box 121 is provided with a suction pump 122. The suction end of the suction pump 122 and one side of the transfer box 121 are communicated with each other.

[0035] The bottom end of the transfer box 121 is provided with a detachable end cover.

[0036] In this embodiment, when the half-opened scraping pipe 10 is at the lowest end, the electromagnetic valve 124 can be automatically started by using the inductor on the inner wall of the shell 1, so that the hollow column opening formed by the half-opened scraping pipe 10 and the inner intercepting pipe 111 is opposite to the inside of the transfer box 121, thereby starting the air suction pump 122 to generate downward suction force on the transfer box 121, and then the dust in the hollow column is directly transferred to the transfer box 121 for separate collection. In the daily drying and filtering process, the electromagnetic valve 124 is set to a normally closed state, and the cleaning frequency is set to periodically collect dust at the inlet end of the shell 1. When the shell 1 works for a long time, the bottom end cover of the transfer box 121 can be disassembled under the closed state of the electromagnetic valve 124, so that the long-term collected dust can be uniformly removed, and the shutdown of the shell 1 is avoided.

[0037] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the present application, and these modifications and changes should be within the protection scope of the present application.
