Description

Technical Field

[0001] This utility model belongs to the technical field of pig farming, and in particular relates to a temperature control device for fermentation equipment. Background Technology

[0002] In the pig farming industry, large-scale pig farms use centralized fermentation equipment. Before adding microbial cultures to the fermentation tanks for fermentation, it is necessary to ensure that the water temperature inside the fermentation tanks is at a suitable level for fermentation. Currently, common solutions include: First, manually adding hot and cold water for mixing, which results in inaccurate temperature control and affects the fermentation effect; Second, using solenoid valves to automatically control the inflow of hot and cold water, which, although it can precisely control the temperature, has high system costs, a complex control system, and is unstable.

[0003] Therefore, how to solve the above problems has become a key research topic in the existing technology field. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a temperature control device for fermentation equipment, which solves the above problems.

[0005] To achieve the above objectives, this utility model discloses a temperature control device for fermentation equipment, comprising a hot water pipe, a cold water pipe, a temperature control valve, and a warm water pipe. Hot water flows through the hot water pipe, and one end of the hot water pipe is connected to the hot water end of the temperature control valve. Cold water flows through the cold water pipe, and one end of the cold water pipe is connected to the cold water end of the temperature control valve. The temperature control valve outputs warm water at a constant temperature, and the outlet end of the temperature control valve is connected to the warm water pipe, which flows into the fermentation equipment. The device also includes a temperature detection device for detecting the temperature of the hot water pipe and a first valve body for controlling the on / off state of the warm water pipe. The temperature detection device is mounted on the hot water pipe, and the first valve body is mounted on the warm water pipe.

[0006] Compared with existing technologies, this application offers the following advantages: The temperature detection device can monitor the water temperature in the hot water pipe, and the temperature control valve ensures that after the hot and cold water are mixed, the output water at a constant temperature meets the requirements and enters the fermentation equipment, thus guaranteeing the fermentation effect. Specifically, when the fermentation equipment needs water, the temperature detection device monitors the temperature in the hot water pipe. If the temperature exceeds the required fermentation temperature, the first valve opens, and the hot and cold water, after being mixed to a suitable temperature by the temperature control valve, enters the fermentation equipment through the warm water pipe. If the temperature detection device detects that the hot water temperature is lower than the required fermentation temperature, the first valve closes, stopping the water intake. Therefore, this invention, by adding a temperature detection device and a temperature control valve to the fermentation equipment, achieves temperature control of the water entering the fermentation equipment. The solution is simple, stable, and has low system cost.

[0007] Furthermore, the hot water pipe includes a first pipe and a second pipe connected to each other via two connectors. The first pipe is connected to the temperature control valve, and the second pipe is connected to the warm water pipe located at the rear end of the first valve body. A second valve body for controlling its on / off state is provided on the second pipe.

[0008] Furthermore, the second valve body includes a first manual valve and a solenoid valve connected in series, with the first manual valve positioned at the front end of the solenoid valve in accordance with the direction of liquid flow.

[0009] Furthermore, it also includes a second hand valve connected in parallel with the solenoid valve. The second hand valve is connected to the inlet and outlet of the solenoid valve through a pipeline, so that when the solenoid valve fails, the second hand valve can be operated to maintain the normal operation of the second pipeline.

[0010] Furthermore, the first valve body and the second valve body have the same structure.

[0011] Furthermore, the temperature control valve is a thermostatic mixing valve.

[0012] Furthermore, the temperature detection device is a temperature probe. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 As shown, this utility model discloses a temperature control device for fermentation equipment, including a hot water pipe 1, a cold water pipe 2, a temperature control valve 3, and a warm water pipe 4. Hot water flows into the hot water pipe 1, and one end of the hot water pipe 1 is connected to the hot water end of the temperature control valve 3. Cold water flows into the cold water pipe 2, and one end of the cold water pipe 2 is connected to the cold water end of the temperature control valve 3. The temperature control valve 3 is used to output warm water at a constant temperature, and the outlet end of the temperature control valve 3 is connected to the warm water pipe 4. The warm water pipe 4 flows into the fermentation equipment 5. It also includes a temperature detection device 6 for detecting the temperature of the hot water pipe 1 and a first valve body for controlling the on / off state of the warm water pipe 4. The temperature detection device 6 is installed on the hot water pipe 1, and the first valve body is installed on the warm water pipe 4.

[0019] Compared with existing technologies, this application has the following advantages: the temperature detection device 6 can detect the water temperature of the hot water pipe 1, and the temperature control valve 3 can ensure that after the hot and cold water are mixed, the output of constant-temperature water that meets the requirements enters the fermentation equipment 5, thereby ensuring the fermentation effect. Specifically, when the fermentation equipment 5 needs water, the temperature detection device 6 detects the temperature in the hot water pipe 1. If the temperature exceeds the water temperature required for fermentation, the first valve opens, and the hot and cold water are mixed to a suitable temperature through the temperature control valve 3 and then enter the fermentation equipment 5 through the warm water pipe 4. If the temperature detection device 6 detects that the hot water temperature is lower than the water temperature required for fermentation, the first valve closes, and the water intake is stopped. Therefore, this invention achieves temperature control of the water entering the fermentation equipment 5 by adding a temperature detection device 6 and a temperature control valve 3 to the fermentation equipment 5. The solution is simple and stable, and the system cost is low.

[0020] Following the above embodiment, more preferably, the hot water pipe 1 includes a first pipe 7 and a second pipe 8 connected to each other via two connectors. The first pipe 7 is connected to a temperature control valve 3, and the second pipe 8 is connected to a warm water pipe 4 located at the rear end of the first valve body. A second valve body for controlling its on / off state is provided on the second pipe 8. It should be noted that during normal operation, the second valve body is in the closed state, and hot water only enters the temperature control valve 3 through the first pipe 7. However, when the fermentation equipment 5 needs to be cleaned, the first valve body is in the closed state, and the second valve body is opened. In this way, hot water directly enters the warm water pipe 4 at the rear end of the first valve body through the second pipe 8, thereby entering the fermentation equipment 5 for cleaning. Cleaning with hot water can improve the cleaning effect and efficiency of the fermentation equipment 5.

[0021] Following the above embodiment, more specifically, the second valve body includes a first manual valve 9 and a solenoid valve 10 connected in series. The first manual valve 9 is positioned at the front end of the solenoid valve 10, according to the direction of liquid flow. Under normal conditions, the first manual valve 9 is in the open state, and the second pipeline 8 is automatically controlled via the solenoid valve 10 without manual operation, saving effort and convenience. When the solenoid valve 10 is under maintenance, the first manual valve 9 can be operated to control the opening and closing of the second pipeline 8.

[0022] Following the above embodiment, a more preferred embodiment further includes a second hand valve 11 connected in parallel with the solenoid valve 10. The second hand valve 11 is connected to the inlet and outlet of the solenoid valve 10 via a pipe, so that when the solenoid valve 10 fails, the second hand valve 11 can be operated to maintain the normal operation of the second pipeline 8. In this way, even if the solenoid valve 10 fails, the normal operation of the second pipeline 8 can still be guaranteed by opening the second hand valve 11.

[0023] Following the above embodiment, more specifically, the first valve body and the second valve body have the same structure. That is, the first valve body on the warm water pipe 4 controls the second pipeline 8 in the same way as the second valve body does. Under normal conditions, the first manual valve 9 on the warm water pipe 4 is in the open state, and the automatic control of the warm water pipe 4 is realized through the solenoid valve 10; when the solenoid valve 10 is under maintenance, the first manual valve 9 can be operated to control the opening and closing of the warm water pipe 4, and the normal operation of the warm water pipe 4 can still be guaranteed through the second manual valve 11.

[0024] Following the above embodiments, more specifically, the temperature control valve 3 is a thermostatic mixing valve. Thermostatic valves, mixing valves, and temperature regulating valves with the same function are all within the scope of protection of this application.

[0025] Furthermore, the temperature detection device is a temperature probe, and thermocouples, resistance temperature detectors, and thermometers with the same function are all within the scope of protection of this application.

[0026] In summary, the design of the temperature detection device 6 and the temperature control valve 3 ensures that the water temperature inside the fermentation equipment 5 is at a suitable fermentation temperature, solving the problem of inaccurate temperature control caused by manually adding hot and cold water for mixing. Compared with simply using a solenoid valve to automatically control the inlet of hot and cold water, this design can accurately control the temperature, and the system is simpler, more stable, and lower in cost.

[0027] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
