[0001] The utility model relates to the technical field of biogas slurry treatment, in particular to biogas slurry treatment equipment. Background Art

[0002] Biogas slurry is a wastewater with high concentration of organic or inorganic matter produced after anaerobic fermentation of food waste. Biogas slurry needs to be kept at a constant temperature during the fermentation process. Biogas slurry contains a large amount of impurities. To ensure the treatment effect, impurity treatment is required before anaerobic fermentation. Existing biogas slurry treatment equipment can only directly perform anaerobic fermentation on biogas slurry, but cannot perform impurity treatment on biogas slurry.

[0003] Therefore, it is necessary to propose a biogas slurry treatment device, which can treat impurities before the biogas slurry is subjected to anaerobic fermentation treatment, thereby improving the anaerobic fermentation treatment effect. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provides a biogas slurry treatment device, which firstly treats impurities before the biogas slurry is subjected to anaerobic fermentation treatment, thereby improving the anaerobic fermentation treatment effect.

[0005] The purpose of the utility model is achieved through the following technical scheme: a biogas slurry treatment device, including a fermentation body with a hollow interior, on which a filter body connected to the interior and hollow inside is arranged, in which a filter screen matching the internal cross-section is arranged, and a first sealing cover is detachably arranged on the filter body.

[0006] A discharge port is arranged at one side of the filter body, the filter screen is arranged obliquely, a lower end of the filter screen is connected to the discharge port, and a second sealing cover is detachably arranged on the discharge port.

[0007] The fermentation body is provided with a liquid outlet, and the liquid outlet is provided with a third sealing cover.

[0008] Water inlet pipes and water outlet pipes are arranged on both sides of the fermentation body. Multiple heat exchange pipes are evenly arranged in the fermentation body, and the multiple heat exchange pipes are connected with the water inlet pipe and the water outlet pipe.

[0009] The inner wall of the fermentation body is hollow, and the inner wall of the fermentation body is separated into left and right sides.

[0010] The inner wall of the fermentation body is hollow, and the inner wall of the fermentation body is separated into left and right sides. The left side of the fermentation body is connected to the water inlet pipe, and the right side is connected to the water outlet pipe. A one-way pressure valve is arranged on the heat exchange tube, and a switch valve is arranged on the water outlet pipe.

[0013] The beneficial effects of the utility model are:

[0014] (1) By setting up a filter part, a filter screen is arranged in the filter part. When the biogas slurry enters the fermentation body, the filter screen can filter out impurities in the biogas slurry, thereby improving the subsequent treatment effect of the biogas slurry. The filter screen is arranged obliquely and the discharge port is opened. Impurities on the filter screen can be discharged from the discharge port by gravity.

In addition, a one-way pressure valve is provided on the heat exchange tube and the outlet pipe. When the internal temperature of the biogas slurry is too high and it is necessary to keep the water in the fermentation body and the heat exchange tube in a flowing state for heat exchange, no matter what the water flow state is, it is ensured that the left inner wall of the fermentation body is filled with water before entering the heat exchange tube and the right inner wall of the fermentation body. When the heat exchange tube and the right inner wall of the fermentation body are filled with water, the water is discharged from the outlet pipe.

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0022] A biogas slurry treatment equipment, reference Figure 1 , comprising a fermentation body 1. A water outlet pipe 4 and a water inlet pipe 3 are connected to the left and right sides of the fermentation body 1. A filter body 2 is connected to the upper end of the fermentation body 1. A liquid outlet 11 is provided on the front side of the fermentation body 1, and a third sealing cover 12 is detachably provided on the liquid outlet 11. Four bases 63 uniformly surrounding the filter body are provided on the upper end of the fermentation body 1. A turntable 64 is fixedly provided on the base 63. A pointer 67 is rotatably provided on the turntable 64. A scale can be provided on the turntable 64 for easy reading.

[0023] refer to Figure 2 The filter body 2 and the fermentation body 1 are hollow inside and connected to each other. A first sealing cover 22 is detachably provided at the upper end of the filter body 2, and a discharge port 23 is provided on the left side. A second sealing cover 24 is detachably provided at the discharge port 23. A filter screen 21 is obliquely provided inside the filter body 2. The height of the left end of the filter screen 21 is lower than that of the right end.

[0024] The inner wall of the fermentation body 1 is hollow and divided into left and right. A plurality of heat exchange tubes 5 are arranged transversely inside the fermentation body 1. The heat exchange tubes 5 are connected to the inner walls on the left and right sides of the fermentation body 1. A first one-way pressure valve 51 is arranged on the heat exchange tube 5. A second one-way pressure valve 41 is arranged on the outlet pipe 4. A slide tube 61 connected to the base 63 is arranged through the upper side of the interior of the fermentation body 1. A slider 62 is arranged on the slide tube 61 for sliding sealing. A gear 65 is rotatably arranged on the base 63. The gear 65 is connected to one end of the pointer 67. A rack 66 meshing with the gear is arranged on the slider 62.

[0025] The operator opens the first sealing cover 22 and pours the biogas slurry into the filter body 2. The filter body 2 is filtered through the filter screen 21 and enters the fermentation body 1 for anaerobic fermentation. Impurities in the biogas slurry are filtered onto the filter screen 21. The second sealing cover 24 is opened, and the impurities are discharged from the discharge port 23 due to their own gravity.

[0026] When the biogas slurry is subjected to anaerobic fermentation treatment in the fermentation body 1, a large amount of heat is generated. Cold water is filled into the right half of the fermentation body 1, the heat exchange tube 5 and the left half of the fermentation body 1 in turn through the water inlet pipe 3, so as to perform sufficient heat exchange with the inside and outside of the biogas slurry and control the temperature of the biogas slurry. Since the biogas slurry generates a very large amount of heat in actual conditions, in order to ensure the heat exchange effect, it is necessary to ensure that the water in the fermentation body 1 is always in a flowing state. Therefore, a first one-way pressure valve 51 is provided on the heat exchange tube 5, and a second one-way pressure valve 41 is provided on the outlet pipe 4 to ensure that no matter how small the amount of flowing water is, the water can first fill the left half of the fermentation body 1, then fill the heat exchange tube 5, and finally fill the right half of the fermentation body 1 before being discharged from the outlet pipe 4.

[0027] Anaerobic fermentation in the fermentation body 1 generates a large amount of gas, causing the internal pressure of the fermentation body 1 to increase, thereby pushing the slider 62 up, and then driving the gear 65 to rotate, thereby rotating the pointer 67. By observing the rotation amplitude of the pointer 67 per time unit, the progress of the anaerobic fermentation can be determined.

[0028] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above description or the technology or knowledge in the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
