Technical Field
[0001] This utility model belongs to the field of circular agriculture technology, specifically relating to a circulating agricultural biogas slurry storage tank. Background Technology
[0002] Circular agriculture is an agricultural development model that focuses on the efficient and circular use of resources, adheres to the principles of "reduction, reuse, and recycling," and is characterized by low consumption, low emissions, and high efficiency.
[0003] Currently, conventional open-air ponds are used for biogas slurry storage in circular agriculture. These ponds have large capacity and are easy to construct. However, external debris can easily fall into the ponds and block the outlet pipes together with the biogas residue at the bottom, affecting the irrigation effect of the biogas slurry downstream. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a circulating agricultural biogas slurry storage tank that avoids blockage of the outlet pipe.
[0005] To achieve the above technical objectives, the present invention adopts the following technical solution:
[0006] A circulating agricultural biogas slurry storage tank includes a tank body, an inlet pipe, a cleaning mechanism, an outlet pipe, and a motor. The tank body has a support frame on its surface, and a fan-shaped dustproof plate is installed on the support frame. The inlet pipe extends into the tank body from the side. The cleaning mechanism is installed in the tank body below the support frame. The outlet pipe is located on the side wall of the tank body below the dustproof plate. The motor is installed above the support frame, and the power output end of the motor is connected to the power input end of the cleaning mechanism.
[0007] Furthermore, the pool wall has a multi-layered anti-seepage structure, consisting of an upper concrete brick layer, an anti-seepage membrane, and a lower concrete cushion layer.
[0008] Furthermore, the cleaning mechanism includes a transmission rod, a water surface scooping net, and a sludge scraper. The transmission rod is installed in the center of the support, with its upper end connected to a motor and its lower end extending into the bottom of the pool. The water surface scooping net is installed on the upper part of the transmission rod below the support at the water surface, and the sludge scraper is installed at the bottom of the transmission rod, contacting the bottom of the pool.
[0009] Furthermore, the pool body is equipped with protective railings on the upper part of the pool wall, and a sludge discharge port is opened at the bottom of the pool body.
[0010] Furthermore, a filter screen is installed at the connection between the water outlet pipe and the pool body.
[0011] According to the above technical solution, the beneficial effects of this utility model are as follows: This utility model adds a dustproof plate to the biogas slurry storage tank to prevent external debris from falling into the biogas slurry storage tank; the dredging net can dredge and collect the biogas residue and debris suspended in the biogas slurry; and the sludge scraper can collect the biogas residue settled at the bottom of the biogas slurry storage tank and discharge it into the sludge discharge pipe.

[0015] To more clearly illustrate the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0016] See Figure 1-2 A circulating agricultural biogas slurry storage tank includes a tank body 1, an inlet pipe 2, a cleaning mechanism 3, an outlet pipe 4, and a motor 5. A support 11 is provided on the surface of the tank body 1, and a fan-shaped dustproof plate 12 is installed on the support 11. The inlet pipe 2 extends into the tank body 1 from the side. The cleaning mechanism 3 is installed in the tank body 1 below the support 11. The outlet pipe 4 is opened on the side wall of the tank body 1 below the support 11, located above the ground. The motor 5 is installed above the dustproof plate 11, and the power output end of the motor 5 is connected to the power input end of the cleaning mechanism 3.
[0017] See Figure 1-2 The pool wall of the pool body 1 has a multi-layer seepage-proof structure, consisting of an upper concrete brick layer, a seepage-proof membrane, and a lower concrete cushion layer. The multi-layer seepage-proof structure of the pool wall can prevent biogas slurry from seeping into the soil and polluting groundwater resources.
[0018] See Figure 1-2The cleaning mechanism 3 includes a transmission rod 31, a water surface scooping net 32, and a sludge scraper 33. The transmission rod 31 is installed in the center of the bracket 11, with its upper end connected to the motor 5 and its lower end extending into the bottom of the tank body 1. The water surface scooping net 32 is installed on the upper part of the transmission rod 31 below the dustproof plate 11. The sludge scraper 33 is installed at the bottom of the transmission rod 31 and contacts the bottom of the tank body 1. The transmission rod 31 drives the water surface scooping net 32 and the sludge scraper 33 to rotate, thereby cleaning the water surface and bottom of the biogas slurry storage tank and accelerating the cleaning efficiency of the biogas slurry storage tank.
[0019] See Figure 1-2 The pool body 1 is equipped with a protective railing 12 on the upper part of the pool wall and a sludge discharge port is opened at the bottom of the pool body 1. The protective railing 12 can improve the safety of the biogas slurry storage pool and prevent accidental falls. The sludge discharge port is opened at regular intervals to facilitate the collection and discharge of sludge.
[0020] See Figure 1-2 A filter screen 41 is installed at the connection between the water outlet pipe 4 and the pool body 1. The filter screen can prevent impurities in the biogas slurry storage pool that have not been treated in time from entering the water outlet pipe 4 and blocking the pipe.
[0021] According to the above embodiments, the working process of this utility model is as follows:
[0022] The biogas slurry produced by the anaerobic digester is introduced into the tank 1 through the inlet pipe 2. At this time, there will be some biogas residue in the biogas slurry. After the biogas slurry is stored in the storage tank for a period of time, some biogas residue will settle at the bottom of the tank 1, and some light biogas residue will also be suspended on the surface. At this time, the motor 5 is started to drive the surface scooping net 32 and the sludge scraper 33. The surface scooping net 32 collects and scoops the suspended solids and biogas residue on the surface of the water, and the sludge scraper 33 discharges the biogas residue at the bottom of the tank into the sludge discharge pipe to prevent impurities from falling into the outlet pipe 3 and blocking the outlet pipe, thus affecting the flow of biogas slurry downstream.
