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

[0002] In large-scale pig farms, centralized fermentation equipment often uses fermentation tanks with a volume exceeding 2 tons. Traditional stirring motors are used to stir the fermented material in the tanks, which presents problems such as high strength of the stirring rods, inconvenient installation, high power consumption of the stirring motor, and high investment and operating costs.

[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 stirring device for centralized fermentation equipment in pig farms, which solves the above problems.

[0005] To achieve the above objectives, this utility model discloses a stirring device for centralized fermentation equipment in pig farms, including an acid pump. The inlet of the acid pump is connected to the acid outlet on the fermentation tank, and the outlet of the acid pump is connected to the inlet of a circulation pipe. The outlet of the circulation pipe extends into the fermentation tank. It also includes a first valve installed on the circulation pipe for controlling its on / off state. Following the liquid flow direction, an acid extraction pipe is connected to the circulation pipe upstream of the first valve. The acid extraction pipe is equipped with a second valve for controlling its on / off state, so that when the second valve is closed and the first valve is open, the fermented material in the fermentation tank is drawn out from the acid outlet and passes through the acid pump and the circulation pipe before re-entering the fermentation tank, thereby achieving the circulation and stirring of the fermented material.

[0006] Compared with existing technologies, this application has the following advantages: The design is ingenious. Utilizing the existing acid pump in the fermentation equipment, and by adding components such as a circulation pipe, a first valve, and a second valve, only one pump is needed for both acid extraction and stirring. No stirring motor or stirring rod is required, making installation convenient and effectively reducing the investment and operating costs of centralized fermentation equipment. Specifically, when stirring is required, the second valve is closed and the first valve is opened. The fermented material in the fermentation tank is drawn out from the acid outlet and passes through the acid pump and circulation pipe before re-entering the fermentation tank, thus achieving the circulation and stirring of the fermented material. When acid extraction is required, the second valve is opened and the first valve is closed. The fermented material in the fermentation tank is drawn out from the acid outlet and passes through the acid pump and acid extraction pipe to a designated location, thus achieving the acid extraction of the fermentation equipment.

[0007] Furthermore, the length of the circulation pipe extending into the fermentation tank is 1 / 2 of the height of the fermentation tank.

[0008] Furthermore, the end of the circulation pipe is connected to the inlet of the circulation port, and the outlet of the circulation port faces the tangential direction of the outer diameter of the fermentation tank.

[0009] Furthermore, the circulation pipeline includes an inner pipeline disposed inside the fermentation tank and an outer pipeline disposed outside the fermentation tank, with the end of the inner pipeline connected to the circulation port; the inner pipeline and the outer pipeline are rotatably connected by a rotating device so that when the rotating device is working, it drives the inner pipeline to rotate inside the fermentation tank.

[0010] Furthermore, the rotating device includes a motor and a rotary joint. The motor's conveying shaft is connected to the rotary joint, the rotary joint's inlet is connected to the outer pipe, and the rotary joint's outlet is connected to the inner pipe, so that when the motor operates, it drives the rotary joint to rotate, thereby driving the inner pipe to rotate.

[0011] Furthermore, the acid outlet is located at the bottom of the fermentation tank.

[0012] Furthermore, the first valve is a first solenoid valve and / or a first manual valve.

[0013] Furthermore, it also includes a sludge extraction pipe located in parallel with the acid extraction pipe and positioned at the rear end of the second valve.

[0014] Furthermore, the second valve includes a second manual valve and a second solenoid valve. According to the flow direction of the liquid, the second manual valve is located at the front end of the second solenoid valve. The inlet of the second manual valve is connected to the circulation pipe located at the front end of the first valve through a pipe. The outlet of the second manual valve is connected to the acid extraction pipe and the sludge extraction pipe respectively. The second solenoid valve is respectively installed on the acid extraction pipe and the sludge extraction pipe.

[0015] Furthermore, it also includes a third hand valve connected in parallel with the second solenoid valve. The third hand valve is connected to the inlet and outlet of the second solenoid valve through a pipe, so that when the second solenoid valve fails, the operation of the third hand valve can maintain the normal operation of the acid extraction pipe and the sewage extraction pipe.

[0021] 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.

[0022] like Figure 1 As shown, this utility model discloses a stirring device for centralized fermentation equipment in pig farms, including an acid pump 1. The inlet of the acid pump 1 is connected to the acid outlet 3 on the fermentation tank 2, and the outlet of the acid pump 1 is connected to the inlet of a circulation pipe 4. The outlet of the circulation pipe 4 extends into the fermentation tank 2. It also includes a first valve 5 set on the circulation pipe 4 for controlling its opening and closing. According to the liquid flow direction, the circulation pipe 4 at the front end of the first valve 5 is also connected to an acid extraction pipe 6. The acid extraction pipe 6 is provided with a second valve 9 for controlling its opening and closing. When the second valve 9 is closed and the first valve 5 is open, the fermented material in the fermentation tank 2 is drawn out from the acid outlet 3 and enters the fermentation tank 2 again through the acid pump 1 and the circulation pipe 4, so as to realize the circulation and stirring of the fermented material.

[0023] Compared with existing technologies, this application has the following advantages: The design is ingenious. Utilizing the existing acid pump 1 in the fermentation equipment, and by adding components such as the circulation pipe 4, the first valve 5, and the second valve 9, only one pump is needed for both acid extraction and stirring. No stirring motor or stirring rod is required, making installation convenient and effectively reducing the investment and operating costs of centralized fermentation equipment. Specifically, when stirring is required, the second valve 9 is closed and the first valve 5 is opened. The fermented material in the fermentation tank 2 is drawn out from the acid outlet 3 and passes through the acid pump 1 and circulation pipe 4 before re-entering the fermentation tank 2, thus achieving the circulation and stirring of the fermented material. When acid extraction is required, the second valve 9 is opened and the first valve 5 is closed. The fermented material in the fermentation tank 2 is drawn out from the acid outlet 3 and passes through the acid pump 1 and acid extraction pipe 6 to a designated location, thus achieving the extraction of acid from the fermentation equipment.

[0024] Following the above embodiment, a more preferable embodiment is that the length of the circulation pipe 4 extending into the fermentation tank 2 is 1 / 2 of the height of the fermentation tank 2. This design ensures that the outlet of the circulation pipe 4 is located in the middle of the fermentation tank 2, meaning that the fermented material pushes the fermented material inside the fermentation tank 2 from the middle, causing it to rotate and agitate, which is beneficial for improving the stirring effect.

[0025] Following the above embodiments, a more preferred embodiment is, as follows: Figure 2 As shown, the end of the circulation pipe 4 is connected to the inlet of the circulation port 7, and the outlet of the circulation port 7 faces the tangential direction of the outer diameter of the fermentation tank 2. The fermentation material in the circulation pipe 4 enters the fermentation tank 2 from the tangential direction of the outer diameter of the fermentation tank 2, which helps to increase the thrust on the fermentation material inside the fermentation tank 2 and improve the stirring effect. Simultaneously, with the continuous discharge from the acid outlet 3, a vortex is easily formed inside the fermentation tank 2, which further facilitates the uniform stirring of the fermentation material and improves the stirring efficiency.

[0026] Following the above embodiment, more preferably, the circulation pipe 4 includes an inner pipe 41 disposed inside the fermentation tank 2 and an outer pipe 42 disposed outside the fermentation tank 2. The end of the inner pipe 41 is connected to the circulation port 7. The inner pipe 41 and the outer pipe 42 are rotatably connected by a rotating device, so that when the rotating device is working, it drives the inner pipe 41 to rotate inside the fermentation tank 2. The rotatable design of the inner pipe 41 enables the circulation port 7 to rotate, thereby adjusting the angle at which the fermented material enters the fermentation tank 2. This allows the fermented material to be pushed outwards from different directions, thereby improving the uniformity of stirring.

[0027] Specifically, the rotating device includes a motor and a rotary joint. The motor's conveying shaft is connected to the rotary joint, the inlet of the rotary joint is connected to the outer pipe 42, and the outlet of the rotary joint is connected to the inner pipe 41, so that when the motor works, it drives the rotary joint to rotate, thereby driving the inner pipe 41 to rotate.

[0028] Following the above embodiment, a more preferable embodiment is that the acid outlet 3 is located at the bottom of the fermentation tank 2, which is more conducive to extracting the fermented material in the fermentation tank 2 and realizing bottom-up circulating stirring.

[0029] Following the above embodiments, more specifically, the first valve 5 is a first solenoid valve 51 and / or a first manual valve 52. In one embodiment, the first valve 5 is a combination of the first solenoid valve 51 and the first manual valve 52, with the first manual valve 52 located at the front end of the first solenoid valve 51. Under normal circumstances, the first manual valve 52 is in a normally open state, and the opening and closing of the circulation pipeline 4 can be controlled by automatically controlling the opening and closing of the first solenoid valve 51. When the first solenoid valve 51 malfunctions, the first manual valve 52 can be manually closed to facilitate the maintenance of the first solenoid valve 51.

[0030] Following the above embodiment, a more preferable method is to further include a sludge extraction pipe 8 located at the rear end of the second valve 9, which is connected in parallel with the acid extraction pipe 6. Through the design of the sludge extraction pipe 8, only one pump is needed for simultaneous acid extraction, stirring, and sludge extraction. Specifically, when the fermentation tank 2 needs sludge extraction, the circulation pipe 4 and the acid extraction pipe 6 are closed, and the sludge extraction pipe 8 is opened to perform sludge extraction.

[0031] Following the above embodiment, more specifically, the second valve 9 includes a second manual valve 91 and a second solenoid valve 92. According to the liquid flow direction, the second manual valve 91 is located at the front end of the second solenoid valve 92. The inlet of the second manual valve 91 is connected via a pipe to the circulation pipe 4 located at the front end of the first valve 5. The outlet of the second manual valve 91 is connected to the acid extraction pipe 6 and the sludge extraction pipe 8, respectively. Second solenoid valves 92 are respectively installed on the acid extraction pipe 6 and the sludge extraction pipe 8. In one embodiment, the inlet of the second manual valve 91 is connected via a pipe to the circulation pipe 4 located at the front end of the first solenoid valve 51 and the rear end of the first manual valve 52. Under normal circumstances, the second manual valve 91 is normally open. The opening and closing of the acid extraction pipe 6 and the sludge extraction pipe 8 can be controlled automatically by controlling the opening and closing of the second solenoid valve 92. When acid extraction is required, the second solenoid valve 92 on the acid extraction pipe 6 is opened and the second solenoid valve 92 on the sludge extraction pipe 8 is closed. When the second solenoid valve 92 malfunctions, the second manual valve 91 can be manually closed to facilitate maintenance of the second solenoid valve 92.

[0032] Following the above embodiment, more specifically, it also includes a third hand valve 10 connected in parallel with the second solenoid valve 92. The third hand valve 10 is connected to the inlet and outlet of the second solenoid valve 92 via a pipe, so that when the second solenoid valve 92 fails, the operation of the third hand valve 10 can maintain the normal operation of the acid extraction pipeline 6 and the sludge extraction pipeline 8. Specifically, if the second solenoid valve 92 on the acid extraction pipeline 6 fails, the third hand valve 10 can be opened, thus ensuring the normal operation of the acid extraction pipeline 6.

[0033] 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.
