DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-4 This is an embodiment of the utility model, which discloses a fertilizer processing dust and exhaust gas recovery device. Specifically, the exhaust gas recovery device includes a tank body 1 and a tank cover 2 connected to the top of the tank body 1. Furthermore, in this embodiment, the outside of the tank body 1 is provided with an exhaust gas inlet, and the top of the tank cover 2 is connected to an exhaust gas outlet. A filter unit 3 is placed on the inside of the tank body 1. A telescopic component 4 is installed on the side of the tank body 1. The telescopic component 4 is connected to the tank cover 2 and is used to support the tank cover 2 to move and rotate. Of course, since the tank cover 2 in this embodiment adopts a movable and rotatable structural design, the exhaust gas outlet on its top should be connected to a flexible pipe, such as a bellows, to provide displacement space. In addition, the exhaust gas inlet described in this embodiment is arranged above the filter unit 3;

[0025] As a preference, the filter unit 3 can be used to filter dust by connecting a mesh to a filler in the prior art, or can be directly filtered by a filter plate structure, which can be selected by technicians in the field, and will not be reviewed here;

[0026] A spray assembly 5 is provided on the inner side of the tank cover 2 , and a pump 6 is connected to the outer side of the tank body 1 . The output end of the pump 6 is connected to the spray assembly 5 through a delivery pipe 7 .

[0027] In some embodiments, the telescopic assembly 4 in the present invention includes a sleeve 41 fixed on the side of the tank body 1, and an insertion rod 43 is movably inserted into the inner side of the sleeve 41 through a spring 42. The insertion rod 43 contacts the spring 42 and is rotatably connected to the sleeve 41. The top end of the insertion rod 43 is fixedly connected to the tank cover 2.

[0028] That is to say, this embodiment adopts the design of a movable plug-in rod 43 for supporting the tank cover 2. When the tank cover 2 needs to be opened, the plug-in rod 43 moves upward under the thrust of the spring 42 to drive the tank cover 2 to move upward. Secondly, since the plug-in rod 43 and the sleeve 41 are rotatable, after the tank cover 2 is opened, the plug-in rod 43 can be rotated to drive the tank cover 2 to rotate to one side of the tank cover 2, thereby realizing convenient removal of the internal filter unit 3 and cleaning and replacement.

[0029] On the basis of the above embodiment, in order to realize the positioning of the moving position of the insertion rod 43, a positioning hole 44 is opened on the outer side of the sleeve 41 in this embodiment, and a positioning glass bead 45 is embedded in the outer side of the insertion rod 43. The telescopic end of the positioning glass bead 45 is engaged with the positioning hole 44, that is, when the insertion rod 43 drives the tank cover 2 to reset downward, the positioning glass bead 45 is engaged with the positioning hole 44 to complete the positioning of the storage position of the insertion rod 43. Similarly, when the insertion rod 43 moves upward, the telescopic end of the positioning glass bead 45 is engaged with the top edge of the sleeve 41 to position the extended position of the insertion rod 43, thereby improving the support stability of the tank cover 2.

[0030] In addition, in this embodiment, a socket is fixed on the top side of the tank cover 2, the insertion rod 43 is plugged into the socket, and a bolt for fastening the insertion rod 43 is threadedly connected to the socket. This structural design is used to achieve a detachable connection between the insertion rod 43 and the tank cover 2, and the initial position of the tank cover 2 can also be adjusted during assembly.

[0031] Furthermore, the spray assembly 5 in this embodiment includes a circular tube 51 fixedly mounted on the inner bottom of the tank cover 2, and a plurality of atomizing nozzles 52 are connected to the circular tube 51. The atomizing nozzles 52 can spray out mist-like water vapor, so that the water mist particles can condense with the dust particles in the exhaust gas and aggregate into large granular dust particles, thereby preventing dust from being discharged with the exhaust gas, making the exhaust gas treatment more environmentally friendly.

[0032] In some embodiments, the delivery pipe 7 in the present invention includes a first pipe 71 connected to the delivery end of the pump 6 and a second pipe 72 connected to the circular pipe 51;

[0033] The first pipe 71 and the second pipe 72 are connected by water via a detachable joint 73. It should be noted that the first pipe 71 and the second pipe 72 described in this embodiment are both configured as rigid pipes, specifically stainless steel pipes, etc. The purpose of adopting the rigid pipe design is to ensure that the water is connected while also realizing the positioning between the tank cover 2 and the tank body 1. That is, when the insertion rod 43 moves downward, the other side of the tank cover 2 is connected by the first pipe 71 and the second pipe 72 to ensure the position stability of the downward movement of the insertion rod 43. Specifically, the detachable joint 73 described in this embodiment is configured as a compression joint, and its plug and socket are respectively connected to the first pipe 71 and the second pipe 72.

[0034] It should be noted that, in the embodiment of the present invention, an annular protrusion 11 is fixedly installed on the inner side of the tank body 1, and the filter unit 3 is placed above the annular protrusion 11. In a movable manner, when the tank cover 2 is raised and rotated, the filter unit 3 can be directly lifted to complete the convenient removal of the filter unit 3, thereby improving the convenience of maintenance;

[0035] The tank body 1 forms a liquid storage portion below the filter unit 3 , and the pump 6 is connected to the liquid storage portion.

[0036] Of course, in order to ensure the sealing of the connection between the tank cover 2 and the tank body 1, the embodiment of the present invention has an outward expansion surface 12 on the top of the tank body 1, and a sealing gasket that fits the tank cover 2 is provided on the outward expansion surface 12.

[0037] In summary, the present invention adopts the design of a liftable and rotatable tank cover 2. When the filter unit 3 inside the tank body 1 has been used for a long time, the tank cover 2 can be opened to conveniently take out the internal filter unit 3, thereby effectively improving the convenience of cleaning and maintenance of the filter unit 3. The telescopic component 4 is used to support the tank cover 2, and the structure is simple and easy to operate, thereby improving the convenience of operating the tank cover 2. In addition, the pump component 6 is used in conjunction with the spray component 5 to spray the cleaning liquid in a reciprocating cycle, which can effectively save the use of cleaning liquid and achieve the purpose of resource recycling and saving.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
