Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment devices, specifically to a simple water bath type cow mattress material system exhaust treatment device. Background Technology

[0002] With the rapid development of the dairy farming industry in China, the number of medium and large-scale farms is increasing, and the problem of centralized manure treatment is becoming increasingly serious. The cattle bedding system is a continuous production equipment that transforms cattle farm manure into hygienic, sterile, and appropriately moist cattle bedding through solid-liquid separation and high-temperature fermentation. In recent years, it has been increasingly widely used in large-scale cattle farms.

[0003] The fermentation process of cow manure can raise the temperature to 60-70℃, accompanied by the generation of a large amount of humid hot steam. This humid hot steam is discharged from the fermentation space through the exhaust chimney by an induced draft fan to remove a large amount of moisture from the fermenting material. Due to the temperature difference between the exhaust pipe and the humid hot steam, this process inevitably produces a large amount of condensate, which needs to be removed promptly. Therefore, conventional cow manure bedding systems, in addition to the vertically upward exhaust chimney, usually have a downward branch, with an open bottom for collection by a floor drain or a water collection hopper, so that the condensate on the inner wall of the chimney can flow back and be discharged. However, this has some drawbacks: the open exhaust structure at the bottom inevitably allows some uncondensed gas to escape into the surrounding air. This uncondensed gas contains a considerable amount of ammonia, which, if released into the plant space, can harm operators. The released ammonia can also easily mix with the condensate on metal surfaces to form ammonia water (NH3·H2O), causing corrosion to metal components and affecting the lifespan of equipment and the plant. Utility Model Content

[0004] The present invention provides a simple water bath type exhaust treatment device for a cow bedding system, which can improve the technical problem of exhaust gas escape in existing cow bedding systems.

[0005] In a first aspect, embodiments of this utility model provide a simple water bath type calf mattress system exhaust treatment device, including a water bath tank. The water bath tank is provided with a water inlet and a drain outlet. A first liquid level switch, a second liquid level switch, and a third liquid level switch are respectively provided in the upper, middle, and lower parts of the water bath tank. The water inlet is provided with a water inlet solenoid valve, and the drain outlet is provided with a drain solenoid valve. The first liquid level switch is communicatively connected to the drain solenoid valve, the second liquid level switch is communicatively connected to the water inlet solenoid valve, and the third liquid level switch is communicatively connected to both the drain solenoid valve and the water inlet solenoid valve. The calf mattress system includes an exhaust chimney arranged vertically, and the lower end of the exhaust chimney is located inside the water bath tank.

[0006] The beneficial effects of the embodiments of this utility model are as follows: In the embodiments of this utility model, the liquid level in the water bath can be controlled by the first liquid level switch, the second liquid level switch, and the third liquid level switch, as well as the water inlet and the drain outlet, so that the liquid level in the water bath is always between the highest and lowest liquid levels, thereby achieving control of the liquid level in the water bath and thus realizing automatic operation of the water bath. By setting the lower end of the exhaust chimney inside the water bath, the exhaust gas discharged from the lower end of the exhaust chimney can be dissolved in the water in the water bath, thereby realizing the recovery and treatment of exhaust gas generated by the cow bedding system and preventing exhaust gas from escaping. The communication connection between the first liquid level switch and the drain solenoid valve, the communication connection between the second liquid level switch and the water inlet solenoid valve, and the communication connection between the third liquid level switch and the drain solenoid valve and the water inlet solenoid valve can be realized by the controller.

[0007] In one embodiment, the height difference between the lower end of the exhaust chimney and the first liquid level switch inside the water bath is ≤150mm.

[0008] The beneficial effects of this invention are as follows: By controlling the height difference between the lower end of the exhaust chimney and the first liquid level switch, the pressure of ammonia dissolved in water within the exhaust chimney can be controlled, thereby achieving better condensation and ammonia removal effects on the water vapor within the exhaust chimney. The height difference between the lower end of the exhaust chimney and the first liquid level switch refers to the height difference between the lowest point of the exhaust chimney outlet and the lower edge of the detection surface of the first liquid level switch.

[0009] In one embodiment, the height difference between the lower end of the exhaust chimney and the third liquid level switch inside the water bath is 10-15 mm.

[0010] The beneficial effects of this utility model embodiment are as follows: By controlling the height difference between the lower end of the exhaust chimney and the third liquid level switch, it can be ensured that the ammonia gas in the exhaust chimney is always below the liquid level in the water bath, preventing the ammonia gas from escaping into the surrounding air. The height difference between the lower end of the exhaust chimney and the third liquid level switch refers to the height difference between the lowest point of the lower outlet of the exhaust chimney and the lower edge of the detection surface of the third liquid level switch.

[0011] In one embodiment, the drain outlet is located at the bottom of the water bath.

[0012] The beneficial effects of the embodiments of this utility model are as follows: by setting the drain port at the bottom of the water bath, it is convenient to drain the liquid in the water bath.

[0013] In one embodiment, a water supply pipe is provided inside the water supply port, and the outlet of the water supply pipe is located below the first liquid level switch.

[0014] Beneficial effects: This utility model utilizes the characteristic that ammonia is highly soluble in water and employs a water bath device for the exhaust treatment of the cow bedding system. While ensuring the condensation effect, it reduces the escape of ammonia. By installing a drain solenoid valve and a water replenishment solenoid valve in the water bath, and equipped with three liquid level switches (high, medium, and low), the drain solenoid valve and the water replenishment solenoid valve operate in an orderly manner under the control of the controller. This allows the condensate in the water bath that is close to saturation with dissolved ammonia to be discharged in a timely manner, and fresh water to be added to the water bath in a timely manner. This maintains the liquid level of the condensate in the water bath within a certain range with slight fluctuations, thereby realizing the cycle of dissolving ammonia, draining liquid, replenishing water, and re-dissolving ammonia.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0019] Firstly, please refer to Figure 1This utility model provides a simple water bath type calf bedding system exhaust treatment device, including a water bath tank 1, which has a water inlet and a drain outlet. The water inlet is equipped with a water inlet solenoid valve 6 to control its opening and closing. The drain outlet is equipped with a drain solenoid valve 3 to control its opening and closing. The drain outlet is located at the bottom of the water bath tank 1 to facilitate the discharge of liquid from the tank. The calf bedding system includes a vertically arranged exhaust chimney 4, the lower end of which is located inside the water bath tank 1. Water vapor generated by the calf bedding system is sent into the exhaust chimney 4 by an induced draft fan. Most of the water vapor is discharged upwards to the outside through the exhaust chimney 4, while a small portion enters the water bath tank 1 from the lower end of the chimney 4.

[0020] A first level switch 7, a second level switch 2, and a third level switch 5 are respectively installed in the upper, middle, and lower parts of the water bath 1. The first level switch 7 is communicatively connected to the drain solenoid valve 3. When the liquid level in the water bath 1 reaches the position of the first level switch 7, the first level switch 7 sends a signal to the drain solenoid valve 3 to open the drain solenoid valve 3, thereby controlling the maximum liquid level in the water bath 1. The second level switch 2 is communicatively connected to the water supply solenoid valve 6. When the liquid level in the water bath 1 reaches the position of the second level switch 2, the second level switch 2 sends a signal to the water supply solenoid valve 6 to close the water supply solenoid valve 6, thereby adjusting the liquid level in the water bath 1 by controlling the water supply solenoid valve 6. The third liquid level switch 5 is communicatively connected to the drain solenoid valve 3 and the water replenishment solenoid valve 6. When the liquid level in the water bath 1 reaches the position of the third liquid level switch 5, the third liquid level switch 5 sends a signal to the drain solenoid valve 3 and the water replenishment solenoid valve 6 to open the water replenishment solenoid valve 6 and close the drain solenoid valve 3, thereby controlling the minimum liquid level height in the water bath 1.

[0021] The height difference between the lower end of the exhaust chimney 4 and the first liquid level switch 7 inside the water bath 1 is ≤150mm, and the height difference between the lower end of the exhaust chimney 4 and the third liquid level switch 5 inside the water bath 1 is 10-15mm. A water supply pipe 8 is installed inside the water supply port, and the outlet of the water supply pipe 8 is located below the first liquid level switch 7.

[0022] During use, the humid hot water vapor generated by the fermentation drum of the cow bedding system is drawn into the exhaust chimney 4 by the induced draft fan. Most of the humid hot water vapor rises along the exhaust chimney 4 and is directly discharged into the outdoor space or guided to a specialized deodorization treatment device; a small portion of the humid hot water vapor enters the water bath 1 along the lower end of the exhaust chimney 4. The treatment process in the exhaust treatment device of this practical simple water bath cow bedding system can be divided into two stages. Stage 1: The condensate droplets on the inner wall of the upper section of the exhaust chimney 4 and a small portion of the humid hot water vapor are introduced into the water bath 1 along the lower end of the exhaust chimney 4. The ammonia in the water vapor continuously dissolves in the water bath liquid. The continuous accumulation of condensate causes the liquid level in the water bath 1 to rise continuously. When the liquid level in the water bath reaches the position of the first liquid level switch 7, the first liquid level switch 7 will send a signal to the controller to open the drain solenoid valve 3, discharging the water bath liquid with high ammonia concentration. Phase 2: As drainage proceeds, the water bath liquid level continuously decreases. When the level drops to the position of the third level switch 5, the third level switch 5 sends a signal to the controller to close the drainage solenoid valve 3, stopping drainage. Simultaneously, the water replenishment solenoid valve 6 opens to replenish water. When the replenished water level reaches the position of the second level switch 2, the second level switch 2 sends a signal to the controller to close the water replenishment solenoid valve 6, stopping water replenishment. Thereafter, under the control of the controller, the drainage solenoid valve 3 and the water replenishment solenoid valve 6 operate sequentially, and the condensate in the water bath 1 will cycle repeatedly through Phases 1 and 2, automatically maintaining the condensate in the water bath 1 at a suitable level.

[0023] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
