Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of livestock breeding waste treatment, and particularly relates to a livestock breeding waste treatment device and a use method thereof. BACKGROUND

[0002] Livestock breeding waste refers to livestock and poultry manure, livestock and poultry shed litter, waste feed and scattered feather waste of a breeding farm, most of which is livestock and poultry manure. A large amount of clean water is used when cleaning livestock and poultry breeding places, and a large amount of manure water mixture with high liquid-solid ratio is generated after flushing. Therefore, the main components of breeding waste include protein, hemicellulose, cellulose, lignin and ash.

[0003] In China, a large proportion of livestock is still raised by scattered households, and these scattered households are usually not good at treating waste generated by livestock breeding. There is a case of directly composting in an open space. However, the manure contains a large number of organic microbial colonies, which consume a large amount of oxygen in the water body during the decomposition of organic matter, and emit a large amount of odor, affecting the quality of underground water and the air environment. At the same time, the manure contains a large amount of smelly water, which is easy to feed mosquitoes and cause certain safety and health hazards.

[0004] Therefore, if the livestock breeding waste is not treated reasonably, it will not only cause serious environmental pollution problems, but also cause waste of resources. Since the moisture content of livestock and poultry manure is high (usually the moisture content is greater than or equal to 80%), the traditional heat treatment processes such as incineration, pyrolysis and gasification inevitably need to be subjected to solid-liquid separation and drying pretreatment, which is high in energy consumption and low in efficiency. Therefore, a livestock breeding waste treatment device that can be popularized is needed.

[0005] Hydrothermal carbonization is a process in which raw materials and water in a proper proportion are reacted in a sealed reactor under a certain temperature and autogenous pressure for a certain time to generate a carbon-rich solid product (hydrothermal carbon). Hydrothermal carbonization can convert biomass into biofuel and stable solid carbon material, realize high-value recycling of low-value waste biomass, and solve the carbon emission problem of waste biomass treatment.

[0078] A method for using the livestock breeding waste treatment device, comprising the following steps:

[0079] A: First, the solid-liquid mixture of livestock breeding waste is introduced into the second inlet 24, the first motor 23 is started to drive the auger 22 to scatter and enter the first cavity 11 through the inlet 13, the third motor 41 is started to drive the driving block 42 and the driving plate 43 to rotate, the driving plate 43 drives the fixed plate 44 in contact with it to rotate, indirectly driving the entire filter assembly to rotate intermittently, preventing the fixed position of the inlet from causing blockage.

After the mixture of fecal water passes through the filter cloth layer 351 and the activated carbon layer 352, the sewage flows to the second cavity 12, and the solid remains above each arc-shaped plate 35. After the feeding is completed, the second telescopic rod 82 is started to drive the horizontal plate 84 to move downward. When the horizontal plate 84 moves below the inlet 13, the shell 1 becomes a closed space at this time. As the horizontal plate 84 moves downward, the pressure in the first cavity 11 increases, which can promote the residual moisture to flow downward through the filter cloth layer 351 and the activated carbon layer 352 into the second cavity. Until the second telescopic rod 82 moves to the preset position, each weight sensor 91 measures the weight of the solid and sends a signal to the controller.

[0080] B: The filtered sewage flows into the second cavity 12, and the liquid level height measured by the liquid level sensor 92 sends a signal to the controller. The volume and the preset density are combined to calculate the weight of the sewage in the second cavity 12, the liquid-solid ratio is calculated, and the sewage in the second cavity 12 is pumped out or supplemented according to the preset liquid-solid ratio. When the liquid-solid ratio is greater than the preset value, the water pump 62 on the outlet pipe is started to pump the sewage in the second cavity 12 into the water tank 63 until the preset liquid-solid ratio is reached. When the liquid-solid ratio is less than the preset value, the second telescopic rod 82 is reset, and the water pump 62 on the inlet pipe is started to supplement the water in the water tank 63. After the supplement, the second telescopic rod 82 is repeatedly operated to move downward until the preset liquid-solid ratio is reached.

[0081] The liquid-solid ratio is 4 to 1.

[0082] C: After the second telescopic rod 82 moves downward to make the shell 1 a sealed space, the second motors 310 are started to drive the first connecting rod 36 to rotate 90 degrees in the forward direction, so that the arc plates 35 change from a flat state to a vertical state, so that the solid residue above the arc plates 35 falls into the second cavity 12. The resistance wire 51 is started to raise the temperature, and at the same time the second telescopic rod 82 is driven to move downward to increase the pressure inside the shell 1, so that the temperature rises to 180°C. The hydrothermal carbonization reaction is carried out for 12 hours. After the reaction is completed, all the sewage in the second cavity 12 is extracted, and the solid hydrothermal carbon produced by the reaction is heated and dried. The second telescopic rod 82 is reset, and the first telescopic rod 71 is started to extend upward, so that one end of the support plate 72 moves upward until it contacts the limiting plate 73. The discharge port 14 is opened to collect the material.

[0083] D: The wastewater generated by the hydrothermal carbonization reaction is added to the water storage tank 63 through the feeding port 65 with microbial agents. After the fourth motor 66 is started to drive the mixing mechanism 67 to mix and stir, the wastewater is discharged through the branch pipe. The water pump body in the water tank 81 is started to rinse the inside of the housing 1 through each of the nozzles 85.

[0084] Example 2

[0085] A livestock breeding waste treatment device, the structure of which is the same as described in Embodiment 1;

[0086] A method for using a livestock waste treatment device, the method comprising the following steps:

[0087] A: First, the solid-liquid mixture of livestock waste is fed into the filter through the second inlet 24. The first motor 23 is started to drive the auger 22 to break up the waste and allow it to enter the first cavity 11 through the inlet 13. The third motor 41 is started to drive the drive block 42 and drive plate 43 to rotate, causing the drive plate 43 to drive the fixed plate 44 in contact with it to rotate, indirectly causing the entire filter assembly to rotate intermittently to prevent the feed position from being fixed and causing blockage. After the drive plate 43 rotates one circumference, it will contact another adjacent fixed plate 44. The manure mixture passes through the filter cloth layer 351 and the activated carbon layer 3. After 52, the wastewater flows to the second chamber 12, while the solids remain above each of the arc-shaped plates 35. After feeding is completed, the second telescopic rod 82 is activated to move the horizontal plate 84 downward. When the horizontal plate 84 moves below the feed inlet 13, the shell 1 becomes a closed space. As the horizontal plate 84 moves downward, the pressure inside the first chamber 11 increases, which can cause the residual water to flow downward into the second chamber through the filter cloth layer 351 and the activated carbon layer 352. Until the second telescopic rod 82 moves to the preset position, each of the weight sensors 91 measures and sends a signal to the controller to measure the weight of the solids.

[0088] B: The filtered wastewater flows into the second chamber 12. The liquid level height measured by the liquid level sensor 92 is sent to the controller. The controller calculates the weight of the wastewater in the second chamber 12 based on the volume and preset density, and calculates the liquid-to-solid ratio. Based on the preset liquid-to-solid ratio, the controller decides whether to pump out or add wastewater to the second chamber 12. When the liquid-to-solid ratio is greater than the preset value, the water pump 62 on the outlet pipe is started to pump the wastewater in the second chamber 12 into the water storage tank 63 until the preset liquid-to-solid ratio is reached. When the liquid-to-solid ratio is less than the preset value, the second telescopic rod 82 is reset, and the water pump 62 on the inlet pipe is started again to add water to the water storage tank 63. After adding water, the operation of moving the second telescopic rod 82 downward is repeated until the preset liquid-to-solid ratio is reached.

[0089] The liquid-to-solid ratio is 4 to 1;

[0090] C: After the second telescopic rod 82 moves downward to make the shell 1 a sealed space, the second motors 310 are started to drive the first connecting rod 36 to rotate 90 degrees in the forward direction, so that the arc plates 35 change from a flat state to a vertical state, and the solid residue above the arc plates 35 falls into the second cavity 12.

[0092] Example 3

[0093] A livestock breeding waste treatment device, the structure of which is the same as described in Embodiment 1;

[0094] A method for using a livestock waste treatment device, the method comprising the following steps:

[0095] A: First, the solid-liquid mixture of livestock waste is fed into the filter through the second inlet 24. The first motor 23 is started to drive the auger 22 to break up the waste and allow it to enter the first cavity 11 through the inlet 13. The third motor 41 is started to drive the drive block 42 and drive plate 43 to rotate, causing the drive plate 43 to drive the fixed plate 44 in contact with it to rotate, indirectly causing the entire filter assembly to rotate intermittently to prevent the feed position from being fixed and causing blockage. After the drive plate 43 rotates one circumference, it will contact another adjacent fixed plate 44. The manure mixture passes through the filter cloth layer 351 and the activated carbon layer 3. After 52, the wastewater flows to the second chamber 12, while the solids remain above each of the arc-shaped plates 35. After feeding is completed, the second telescopic rod 82 is activated to move the horizontal plate 84 downward. When the horizontal plate 84 moves below the feed inlet 13, the shell 1 becomes a closed space. As the horizontal plate 84 moves downward, the pressure inside the first chamber 11 increases, which can cause the residual water to flow downward into the second chamber through the filter cloth layer 351 and the activated carbon layer 352. Until the second telescopic rod 82 moves to the preset position, each of the weight sensors 91 measures and sends a signal to the controller to measure the weight of the solids.

[0096] B: The filtered wastewater flows into the second chamber 12. The liquid level height measured by the liquid level sensor 92 is sent to the controller. The controller calculates the weight of the wastewater in the second chamber 12 based on the volume and preset density, and calculates the liquid-to-solid ratio. Based on the preset liquid-to-solid ratio, the controller decides whether to pump out or add wastewater to the second chamber 12. When the liquid-to-solid ratio is greater than the preset value, the water pump 62 on the outlet pipe is started to pump the wastewater in the second chamber 12 into the water storage tank 63 until the preset liquid-to-solid ratio is reached. When the liquid-to-solid ratio is less than the preset value, the second telescopic rod 82 is reset, and the water pump 62 on the inlet pipe is started again to add water to the water storage tank 63. After adding water, the operation of moving the second telescopic rod 82 downward is repeated until the preset liquid-to-solid ratio is reached.

[0097] The liquid-to-solid ratio is 4 to 1;

[0098] C: After the second telescopic rod 82 moves downward to make the shell 1 a sealed space, the second motors 310 are started to drive the first connecting rod 36 to rotate 90 degrees in the forward direction, so that the arc plates 35 change from a flat state to a vertical state, and the solid residue above the arc plates 35 falls into the second cavity 12. The resistance wire 51 is started to raise the temperature, and at the same time the second telescopic rod 82 is driven to move downward to increase the pressure inside the shell 1, so that the temperature rises to 260°C. The hydrothermal carbonization reaction is carried out for 6 hours. After the reaction is completed, all the sewage in the second cavity 12 is extracted, and the solid hydrothermal carbon produced by the reaction is heated and dried. The second telescopic rod 82 is reset, and the first telescopic rod 71 is started to extend upward, driving one end of the support plate 72 to move upward until it contacts the limiting plate 73. The discharge port 14 is opened to collect the material.

[0099] D: The wastewater generated by the hydrothermal carbonization reaction is added to the water storage tank 63 through the feeding port 65 with microbial agents. After the fourth motor 66 is started to drive the mixing mechanism 67 to mix and stir, the wastewater is discharged through the branch pipe. The water pump body in the water tank 81 is started to rinse the inside of the housing 1 through each of the nozzles 85.
