Description

Technical Field

[0001] The present application relates to the technical field of exhaust facilities for cream tanks, and in particular to an exhaust device for a cream tank. Background Art

[0002] Cream refers to the light cream obtained by centrifugally separating milk, and is a dairy product made by stirring, disinfecting, filling, and packaging. During the production process of cream, cream is added to the cream tank when passing through the production process. Generally, an exhaust device is installed on the cream tank, and the exhaust device can be used to discharge the gas generated in the cream tank.

[0003] Under the existing technology, the exhaust device of the cream tank generally uses a one-way air guiding structure to enable the gas in the cream tank to be discharged through the exhaust device, and to prevent external air from mixing into the cream tank. However, when cleaning the cream tank, there is a certain pressure inside the cream tank, and the cleaning liquid is likely to spray out from the exhaust port, and the cleaning liquid is also likely to remain in the exhaust device, thereby affecting its subsequent use. Utility Model Content

[0004] In order to improve the problems proposed in the above background art, the present application provides an exhaust device for a cream tank.

[0005] An exhaust device for a cream tank provided by the present application adopts the following technical solutions:

Specific embodiments

[0019] The technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] An exhaust device for a cream can is disclosed in an embodiment of the present application. Refer to Figures 1 to 3 , the exhaust device of the cream can includes a housing part 10, a machine cover part 20, an exhaust pipe 40 and an opening and closing part 50. Openings are formed on the side and the lower end of the housing part 10. The machine cover part 20 is detachably covered on the side of the housing part 10, and an inlet 30 is formed between the machine cover part 20 and the housing part 10. When the exhaust device is installed and used, the inlet 30 can be used to communicate with the cream can. The exhaust pipe 40 is installed in the housing part 10. One end of the exhaust pipe 40 communicates with the inlet 30, and the other end of the exhaust pipe 40 passes out of the outside of the housing part 10 and the machine cover part 20. The exhaust pipe 40 is used to discharge the gas generated in the cream can to the outside. The opening and closing part 50 is installed in the housing part 10, and the opening and closing part 50 is used for the opening and closing operation of the inlet 30, so that when the cream can is cleaned, the opening and closing part 50 can be used to block the inlet 30 to prevent the cleaning liquid from entering the housing part 10 and the exhaust pipe 40.

[0021] Refer to Figure 4, the housing part 10 includes a side surface and a base box 11 with an opening formed at the lower end. An inner box 12 is formed at the inner top of the base box 11, and an L-shaped groove 13 for installing and setting the opening and closing part 50 is formed in the base box 11. The inner box 12 is used for installing and setting the exhaust pipe 40, and a pipe through hole 14 that cooperates with the exhaust pipe 40 and penetrates the inner box 12 is formed on the inner box 12. An outwardly protruding connection port 15 is formed at the lower end opening of the base box 11, and the connection port 15 and the machine cover part 20 fixed by shielding on its side surface can be combined to form an inflow port 30. A limiting step 16 for limiting the shielding mechanism in the opening and closing part 50 can be formed on the inner side of the connection port 15.

[0022] Refer to Figure 3 , the exhaust pipe 40 includes an input section 41, a diversion section 42, a one-way valve, and an output section 43. The input section 41 and the output section 43 are respectively connected and arranged at both ends of the diversion section 42, and the input section 41 and the output section 43 pass through the pipe through hole 14 on the inner box 12, so that when exhausting gas, the air flow can flow through the input section 41, the diversion section 42, and the output section 43 in sequence from the inflow port 30. A one-way valve is installed in the diversion section 42, and the one-way valve can be used to make the air flow only discharge outward from the cream can and prevent external air from entering the cream can.

[0023] Refer to Figure 5 , the opening and closing part 50 includes a driving mechanism, a transmission mechanism, and a shielding mechanism. The output end of the driving mechanism is connected to the transmission mechanism, and the transmission mechanism can be driven to be movably arranged in the housing part 10. The shielding mechanism is connected to the transmission mechanism, and the shielding mechanism can be driven to move, thereby adjusting the opening and closing states of the inflow port 30.

[0024] The driving mechanism includes a guide frame 51, a support frame 55, a linear driving source 56, and a push rod 57. The support frame 55 is installed and fixed on the inner wall of the top of the guide frame 51. The top of the linear driving source 56 is connected and fixed to the support frame 55. The output end of the linear driving source 56 is clamped and connected to the adjacent end of the push rod 57, so that the push rod 57 can be driven to move up and down. The aforementioned linear driving source 56 can adopt driving sources such as electric push rods, pneumatic push rods, or hydraulic push rods existing in the prior art. The other end of the push rod 57 is used for cooperating and connecting with the transmission mechanism.

[0025] The transmission mechanism includes a slider 52 and a parallel link 53. A chute 511 is formed on the side surface of the guide frame 51, and the slider 52 is slidably arranged in the chute 511. The parallel link 53 includes two rod bodies of equal length and parallel to each other. The side of the slider 52 facing the push rod 57 is fixedly connected to the adjacent end of the push rod 57, so that it can be driven to move up and down in the chute 511. One ends of the two rod bodies close to the slider 52 are respectively rotatably connected to both ends of the slider 52, and the other ends of the two rod bodies are used for cooperating and connecting with the shielding mechanism.

[0026] The shielding mechanism includes a cover plate 54 whose shape and size are adapted to those of the inlet port 30. On the side of the cover plate 54 facing the inside of the casing portion 10, two connecting lugs 541 are formed, and the two connecting lugs 541 are respectively rotatably connected to the two rod bodies.

[0027] When the slider 52 moves downward in the chute 511, limited by the inner wall of the vertical portion in the L-shaped groove 13, the parallel link 53 cannot deflect, and the cover plate 54 moves downward as a whole following the transmission mechanism. When the cover plate 54 faces the horizontal portion of the L-shaped groove 13 and faces the inlet port 30, at this time the L-shaped groove 13 no longer blocks the movement of the cover plate 54, and during the continuous downward movement of the slider 52 in the chute 511, the parallel link 53 can be deflected, and the cover plate 54 is pushed towards the inlet port 30 until it abuts against the limiting step 16 and shields the inlet port 30.

[0028] The system of the present invention may further include a control system for controlling the operation of the above-mentioned linear drive source to perform automatic operation of opening and closing the inlet port. It should be understood that there is no particular limitation on this control system, and it can be implemented by control techniques in the prior art, which will not be elaborated here.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
