DETAILED DESCRIPTION
[0021] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described in combination with specific embodiments.
[0022] Please refer to Figures 1 to 3 The utility model provides a technical scheme: a cold storage ventilation device, including warehouse outer wall 1 and air filter part 6, the warehouse outer wall 1 is the outer wall of cold storage, and the air filter part 6 has the effect of filtering and sterilizing air.
[0023] In the technical solution, two adapter tubes 3 are installed on one side of the warehouse outer wall 1 close to the top, the adapter tubes 3 are air inlets into the cold storage, in use, a wall hole can be processed on the warehouse outer wall 1, then the adapter tubes 3 are installed on the wall of the warehouse outer wall 1 through flanges and bolts, and one end of the adapter tubes 3 is inserted into the wall hole. The two adapter tubes 3 are arranged close to the two ends of the warehouse outer wall 1, and the outer port ends of the two adapter tubes 3 are rotatably connected with the telescopic air pipes 4. The positions at which the two adapter tubes 3 are installed increase the speed of the fresh air covering the cold storage. A three-way air pipe 5 is slidably connected to the middle of one side of the warehouse outer wall 1. Two rear straight pipes 51 on the three-way air pipe 5 are rotatably connected with the free ends of the telescopic air pipes 4 connected with the two adapter tubes 3. In specific implementation, preferably, the two ends of the telescopic air pipe 4 are respectively welded with an adapter elbow one 41 and an adapter elbow two 42. One section of the adapter elbow one 41 is sleeved in the adapter tube 3. A sealing rubber sleeve one 31 is nested in the adapter tube 3. The sealing rubber sleeve one 31 is located at the rotating connection position of the adapter elbow one 41 and the adapter tube 3, and plays a sealing role. One end of the adapter elbow two 42 is sleeved in the rear straight pipe 51. A sealing rubber sleeve two 512 is nested in the rear straight pipe 51. Similarly, the sealing rubber sleeve two 512 is arranged at the rotating connection position of the adapter elbow two 42 and the rear straight pipe 51, and also plays a sealing role. The external air enters the three-way air pipe 5, is then divided into two parts by the two telescopic air pipes 4, and finally enters the cold storage. When the three-way air pipe 5 moves up and down, the telescopic air pipes 4 on the two sides of the three-way air pipe 5 perform telescopic action. Specifically, the telescopic air pipe 4 has a two-section telescopic structure, and the telescopic sliding positions of the two sections are provided with a sealing rubber sleeve three 43, so that the sealing degree of the telescopic movement of the telescopic air pipe 4 is improved.
[0024] The front straight pipe 52 is detachably connected with an air filter part 6. When the telescopic air pipe 4 is lowered to a position close to the ground, the height of the air filter part 6 is also lowered, so that the maintenance personnel can replace the air filter part 6 on the ground. One side of the warehouse outer wall 1 is provided with a control combination 7 for controlling the lifting of the three-way air pipe 5.
[0025] Specifically, the control combination 7 includes a positioning plate 71 and a lead screw 72. The positioning plate 71 is fixedly arranged on the outer side wall of the warehouse outer wall 1. The lead screw 72 is rotatably connected to one side of the positioning plate 71. A connecting plate 511 is fixedly connected between the two rear straight pipes 51. A lead sleeve 5111 that is screw-connected with the lead screw 72 is welded on the connecting plate 511. When the lead screw 72 rotates, the rotating action can drive the lead sleeve 5111 to move up and down, thereby driving the three-way air pipe 5 to move up and down. In use, a control motor 8 is fixedly connected to one side of the positioning plate 71. The output shaft of the control motor 8 is fixedly connected with the bottom of the lead screw 72. The control motor 8 provides driving force for the rotation of the lead screw 72.
[0026] A fan 2 is arranged in the front straight pipe 52 of the three-way air duct 5, and the fan 2 is installed at the rear of the air filtering part 6. When the fan 2 is started, the speed and flow of the external air passing through the air filtering part 6 can be improved, and the supply of fresh air can be increased.
[0027] In the embodiment, the air filtering part 6 is disc-shaped, and a notch 521 is formed at the top of the front straight pipe 52 and is matched with the air filtering part 6. That is, the air filtering part 6 can be inserted into the front straight pipe 52 through the notch 521, and the air filtering part 6 can be removed by pulling it upwards. The structure of the insertion and matching combination makes the replacement of the air filtering part 6 more convenient.
[0028] Further, a support column 9 is connected to the bottom of the front straight pipe 52 in a penetrating and up-and-down sliding manner. The top of the support column 9 is opposite to the air filtering part 6. When the front straight pipe 52 is lowered to a certain height, the bottom of the support column 9 is in contact with the ground. When the front straight pipe 52 continues to drop, the support column 9 will push the air filtering part 6 outwards, and the air filtering part 6 can be removed more easily.
[0029] The air filtering part 6 includes a positioning ring 61 and a filtering and sterilizing part 62 embedded in the positioning ring 61. The two sides of the positioning ring 61 are bonded with sealing rings 611. The sealing rings 611 improve the sealing degree of the combination of the positioning ring 61 and the front straight pipe 52. The filtering and sterilizing part 62 includes filter cotton and activated carbon, which are stacked in front of and behind each other after being packaged. The filter cotton filters dust and sundries in the air, and the activated carbon adsorbs bacteria in the air.
[0030] Working principle: when the air filtering part 6 needs to be replaced, the control motor 8 is started, the screw rod 72 is rotated to drive the silk sleeve 5111 to drop, the three-way air duct 5 carrying the air filtering part 6 drops, and the support column 9 is in contact with the ground. The support column 9 will push the entire air filtering part 6 out of the notch 521. Then, the bottom of the new air filtering part 6 is inserted into the top of the notch 521, and the three-way air duct 5 is controlled to rise slightly, so that the air filtering part 6 is pressed into the front straight pipe 52. Finally, the three-way air duct 5 is controlled to rise and reset.
[0031] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
