Description

Technical Field

[0001] The utility model relates to the technical field of dehumidifiers, in particular to a self-cleaning rotary dehumidifier. Background Art

[0002] In the production process of new energy cathode materials, a rotary dehumidifier is generally used to control the temperature and humidity of the workshop. However, because a lot of dust is generated during the production process, the core component of the rotary dehumidifier, the "rotor", will become dirty and clogged, affecting the dehumidification efficiency. The dust particles in the production process are extremely small. Even if a filter is installed in front of the wheel, the wheel will still become dirty and clogged over time in the actual production process.

[0003] In the prior art, the general solution process for the dirty and blocked condition of the impeller is: the staff determines whether the dirty and blocked condition affects the dehumidification of the dehumidifier - shuts down the dehumidifier - uses compressed air to spray the impeller - removes dust - restarts the machine after cleaning. The above process of cleaning the dirty and blocked impeller has the following problems:

[0004] 1. The cleaning process requires shutdown, which affects workshop production.

[0005] 2. The dirtiness, blockage and cleanliness conditions are judged manually, and ineffective cleaning is caused by poor technical skills and lack of responsibility of the personnel.

[0006] 3. The entire cleaning process takes a long time, is time-consuming and labor-intensive, and affects production efficiency. Utility Model Content

[0023] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the present application.

[0024] As attached Figure 1 As shown, the utility model provides a self-cleaning rotary dehumidifier, including a box body 1, in which a front surface cooler 2, a compressed air injection device 3, a rotary wheel 4, a telescopic dust collecting device 5, a rear surface cooler 6, a fan 7, and a filter 8 are arranged in sequence along the air inlet direction. The telescopic dust collecting device 5 includes a dust collecting bag 51 and a telescopic mechanism for controlling the telescopic movement of the dust collecting bag 51.

[0025] The utility model can start the compressed air injection device 3 regularly to clean the runner 4, and can also start the compressed air injection device 3 to clean the runner 4 according to the dirt and blockage of the runner 4. Before starting the compressed air injection device 3, the telescopic mechanism is first started to expand the dust collecting bag 51 to facilitate dust collection.

[0026] Further, as attached Figure 2 As shown, the telescopic mechanism includes a motor 52, a slide rail 53, and a screw rod 54. The slide rail 53 and the screw rod 54 are both arranged in parallel in two numbers and are symmetrically arranged on both sides of the rotating wheel 4 along the circumferential direction. The slide rail 53 is fixedly connected to the box body 1, and the screw rod 54 is rotationally connected to the box body 1. The motor 52 is transmission-connected to one of the screw rods 54. The two screw rods 54 are connected by a synchronous belt 55 / chain. The screw rod 54 is provided with a nut 56 that cooperates with it. The nut 56 is slidably connected to the slide rail 53. At least two ends of the opening of the dust bag 51 are fixed in the box body 1, and at least the other two ends of the opening of the dust bag 51 are respectively arranged on two nuts 56.

[0027] Specifically, the dust bag 51 has an opening. When the opening of the dust bag 51 is unfolded, it corresponds to the position of the compressed air injection device 3 and can cover the lower half of the rotating wheel 4. Therefore, when the compressed air injection device 3 is started, the compressed air carries the dust on the rotating wheel 4 into the dust bag 51, so that the dust is collected in the dust bag 51, and the air after dust removal is discharged from the dust bag 51. The opening of the dust bag 51 is divided into at least four corners, wherein two adjacent corners are fixed in the box body 1, and the other two corners move with the nut 56, so as to control the opening and closing of the opening of the dust bag 51. The rotation of the screw rod 54 is controlled by the operation of the motor 52. Since the nut 56 is threadedly matched with the screw rod 54 and is slidably connected with the slide rail 53, when the screw rod 54 rotates, the nut 55 moves along the slide rail 53, thereby driving the two ends of the opening of the dust bag 51 to move, and controlling the opening and closing of the opening of the dust bag 51.

[0028] Further, such as Figure 2 , Figure 3 As shown, the dust collecting bag 51 is detachably connected to the nut 56, a limiting ring 57 is arranged on the opening of the dust collecting bag 51, and a "T-shaped" limiting column 58 adapted to the limiting ring 57 is threadedly arranged on the nut 56. The limiting ring 57 is fixed between the nut 56 and the "T-shaped" limiting column 58 through the "T-shaped" limiting column 58, so as to facilitate the replacement of the dust collecting bag 51.

[0029] Further, such as Figure 2 As shown, a plurality of slide blocks 59 are disposed on the slide rail 53, and the opening of the dust collecting bag 51 is connected to the slide blocks 59, so that the opening of the dust collecting bag 51 can be fixed in multiple directions.

[0030] Furthermore, the opening of the dust bag 51 is detachably connected to the slider 59. Specifically, a limiting ring 57 is provided on the opening of the dust bag 51, and a "T-shaped" limiting column 58 adapted to the limiting ring 57 is threadedly provided on the slider 59, and the limiting ring 57 is fixed between the slider 59 and the "T-shaped" limiting column 58 through the "T-shaped" limiting column 58. The dust bag 51 is easily replaced.

[0031] Furthermore, the self-cleaning rotary dehumidifier also includes a controller and a pressure difference sensor 6 connected to the controller. The pressure difference sensor 6 is arranged in the rotary section. The pressure difference sensor 6 is used to detect the pressure difference on the front and rear sides of the rotary wheel 4 along the air inlet flow. An electric valve is arranged on the compressed air injection device 3, and the electric valve is connected to the controller.

[0032] The utility model provides a self-cleaning rotary dehumidifier with a pressure difference sensor and a built-in compressed air injection device in the rotary section. The compressed air injection device is controlled by an electric valve. The pressure difference sensor and the electric valve of the compressed air injection device are jointly controlled. When the rotary wheel is dirty and clogged, the feedback pressure of the rotary wheel pressure difference sensor will increase. When the first set pressure is reached (such as the first set pressure is 600Pa), the electric valve will be opened to spray compressed air on the rotary wheel to clean the dust on the rotary wheel. When the pressure drops to the second set pressure (such as the second set pressure is 300Pa) and the purge time is met, the electric valve will be managed to end the cleaning. In this way, the adsorption capacity of the rotary wheel is restored.

[0033] Furthermore, the controller is connected to the motor 52 of the telescopic mechanism to control the telescopic movement of the dust collecting bag 51 .
