[0038] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] like Figure 1-6As shown, the utility model discloses a biochemical treatment device for food waste, including a shell 1 and a biochemical reaction box 2, a constant temperature control system 3, a first water spraying device 5 and a water storage device 4 arranged in the shell 1, wherein the biochemical reaction box 2 is used for biochemical degradation treatment of food waste; the constant temperature control system 3 is located on one side of the biochemical reaction box 2, and the water storage device 4 is located below the constant temperature control system 3, and the water in the water storage device 4 is cooled or heated by the constant temperature control system 3; the first water spraying device 5 is fixed to the top of the biochemical reaction box 2, and the water inlet of the first water spraying device 5 is connected to the water storage device 4, and the water in the water storage device 4 is sprayed into the biochemical reaction box 2 by the first water spraying device 5 to realize the regulation of the temperature in the biochemical reaction box 2.

[0040] When in use, the temperature in the biochemical reaction box 2 is monitored. If the temperature in the biochemical reaction box 2 is lower than the set threshold, the constant temperature control system 3 heats the water in the water storage device 4, and the first water spraying device 5 sprays the heated water into the biochemical reaction box 2 to cause the temperature in the biochemical reaction box 2 to rise. When it is monitored that the temperature in the biochemical reaction box 2 reaches the set threshold, the water spraying is stopped and the biochemical degradation of the food waste is carried out; if the temperature in the biochemical reaction box 2 is higher than the set threshold, the constant temperature control system 3 cools the water in the water storage device 4, and the first water spraying device 5 sprays the cooled water into the biochemical reaction box 2 to cause the temperature in the biochemical reaction box 2 to decrease. When it is monitored that the temperature in the biochemical reaction box 2 reaches the set threshold, the water spraying is stopped and the biochemical degradation of the food waste is carried out. In the present application, the temperature in the biochemical reaction box 2 is regulated by the constant temperature control system 3, the water storage device 4 and the first water spray device 5. Compared with the temperature regulation by the electric heating plate in the prior art, it can not only achieve the regulation of the biochemical reaction temperature being too high or too low, but also further improve the accuracy of the biochemical reaction temperature regulation; at the same time, it can also reduce the equipment cost.

[0041] Furthermore, the biochemical reaction box 2 includes a box body 21, a box door 22 and a stirring device 23. A reaction chamber 201 is provided in the box body 21. The reaction chamber 201 is used to hold food waste and reaction fillers. A feed port connecting the outside and the reaction chamber 201 is provided on the top of the box body 21. The box door 22 is hinged to the feed port of the box body 21. The stirring device 23 is located in the reaction chamber 201 and is used to mix and stir the materials in the reaction chamber 201. The reaction fillers include active bacterial strains and fillers. The active bacterial strains include one or more of any active bacteria with good biodegradability, including Bacillus subtilis, lactic acid bacteria, yeast, etc. The fillers include any materials that can provide a living environment for the growth and reproduction of the strains, including straw, tea residues, fruit wood chips, etc. The specific types of active bacterial strains and fillers are not limited in this application. When in use, reaction fillers and food waste are sequentially added into the biochemical reaction box 2 through the feed port, and the reaction fillers and food waste are mixed and stirred by the stirring device 23 to promote full contact and reaction between the food waste and the reaction fillers, thereby achieving biochemical degradation of the food waste.

[0042] Furthermore, the stirring device 23 includes a rotating rod 231 and a stirring paddle 232. The rotating rod 231 is arranged along the length direction of the box body 21, and the two ends of the rotating rod 231 are movably connected to the inner wall of the box body 21. There are multiple stirring paddles 232, and the multiple stirring paddles 232 are fixedly installed on the rotating rod 231. The lengths of the multiple stirring paddles 232 are all less than half of the width of the reaction chamber 201, and the initial rotation positions between two adjacent stirring paddles 232 are staggered. By rotating the multiple stirring paddles 232 driven by the rotating rod 231, the food waste and the reaction filler can be fully stirred and mixed.

[0043] Further, the box body 21 is set in a cubic shape, and an arc is set at the bottom thereof. A plurality of filter holes 202 are centrally set along the length direction of the box body 21 at the bottom of the arc, and the filter holes 202 are used to discharge the water in the reaction chamber 201. The arc is set at the bottom of the box body 21, which can promote the water generated during the biochemical degradation of the food waste in the reaction chamber 201 to converge to the bottom of the box body 21. The filter hole 202 is set in the center of the bottom, that is, at the lowest point of the arc bottom, so that the water is generated and converged to the lowest point of the bottom under the action of its gravity and discharged through the filter hole 202. The filter hole 202 is set in a long strip shape, and the width of the filter hole 202 is 0.5mm to 5mm. The filter holes 202 are set in at least three groups, and the three groups of filter holes 202 are all arranged in parallel along the length direction of the box body 21, and the filter holes 202 of adjacent groups are staggered. The above-mentioned configuration can promote the discharge of water after the reaction in the reaction chamber 201 through the filter holes 202, thereby preventing undegraded food waste from being discharged through the filter holes 202; setting multiple groups of filter holes 202 can better promote the discharge of water and reduce the clogging of the filter holes 202 by garbage in the reaction chamber 201.

[0044] Furthermore, the first water spray device 5 is circumferentially fixed to the feed port. The first water spray device 5 is a water pipe arranged along the circumference of the feed port. A plurality of water spray holes (not shown in the figure) are arranged on the side of the water pipe facing the reaction chamber 201. Water is sprayed into the reaction chamber 201 through the water spray holes. The water inlet of the first water spray device 5 is connected to the water storage device 4 to spray the heated or cooled water in the water storage device 4 into the reaction chamber 201, so as to achieve the purpose of increasing or decreasing the reaction temperature in the reaction chamber 201.

[0045] Furthermore, it also includes a second water spray device 6, which is located below the biochemical reaction box 2 and is arranged along the length direction parallel to the box body 21, wherein the second water spray device 6 is a high-pressure water pipe arranged along the length direction parallel to the box body 21, and the second water spray device 6 is provided with a plurality of water spray nozzles 61 on the side facing the filter hole 202, and the water spray range of the water spray nozzles 61 corresponds to the filter hole 202. When in use, in the process of discharging the water in the reaction chamber 201 through the filter hole 202, there is still the problem of garbage residue blocking the filter hole 202. By arranging the second water spray device 6 parallel to the filter hole 202, the water spray nozzles 61 on the second water spray device 6 are prompted to spray water at high pressure on the filter hole 202, and under the action of the high-pressure water spray, the garbage residue blocked on the filter hole 202 is flushed to avoid the garbage residue blocking the filter hole 202.

[0046] Furthermore, a wastewater trough 7 is provided below the second water spray device 6. The length of the wastewater trough 7 is equal to the length of the biochemical reaction box 2, and the width of the wastewater trough 7 is equal to the width of the biochemical reaction box 2. The wastewater filtered and discharged from the biochemical reaction box 2 can be collected through the wastewater trough 7, and the water sprayed by the second water spray device 6 can also be collected. A drain port 71 is provided on one side of the wastewater trough 7 to discharge the water in the wastewater trough 7 to the outside of the biochemical treatment equipment for the next step of wastewater treatment.

[0047] Furthermore, it also includes an electric heating wire 24, which is arranged on the outer wall of the bottom of the box body 21 and is located on both sides of the filter hole 202. The electric heating wire 24 is distributed in an S shape, which can increase the contact area between the electric heating wire 24 and the box body 21. In winter, when the external ambient temperature is low, the heating efficiency is low only by spraying hot water through the first water spray device 5, and it will cause too much water in the reaction chamber 201. By setting the electric heating wire 24, the first water spray device 5 can be assisted to heat the reaction chamber 201, thereby improving the heating efficiency.

[0048] Furthermore, a temperature sensor (not shown in the figure) is included, which is arranged in the reaction chamber 201. There are 2 to 4 temperature sensors, which are used to monitor the temperature in the reaction chamber 201. The temperature sensor is electrically connected to the constant temperature control system 3. The temperature in the reaction chamber 201 is monitored by the temperature sensor, and the temperature of the temperature sensor is transmitted to the constant temperature control system 3 in real time, so that the constant temperature control system 3 heats or cools the water in the water storage device 4 according to the temperature of the temperature sensor.

[0049] Furthermore, the water storage device 4 includes a water tank 41 and a water pump 42, wherein the water tank 41 is located below the constant temperature control system 3, and the water pump 42 is located on one side of the water tank 41, wherein the water inlet of the water pump 42 is connected to the water tank 41, and the water outlet is respectively connected to the water inlets of the first water spraying device 5 and the second water spraying device 6, thereby supplying water to the first water spraying device 5 and the second water spraying device 6. The water tank 41 is connected to an external water source for automatic water replenishment.

[0050] Furthermore, the food waste biochemical treatment equipment of the present application also includes a general control system 8, which is located on the side of the biochemical reaction box 2 away from the constant temperature control system 3. The general control system includes a number of control switches and a control panel. The general control system 8 is electrically connected to the temperature sensor, the constant temperature control system 3, the first water spray device 5, the second water spray device 6 and the water storage device 4, and each operation is controlled by the general control system 8. It should be noted that the constant temperature control system 3 is any device that can realize cooling or heating the water in the water tank 41, such as a heat pump circulation device, etc., which is not limited in this application. A heat dissipation component 31 is provided on the side of the constant temperature control system 3 away from the biochemical reaction box 2, and the constant temperature control system 3 is cooled by the heat dissipation component 31 to avoid excessive temperature in the constant temperature control system 3.

[0051] When in use, the reaction filler and food waste are sequentially added into the biochemical reaction box 2 through the feed port, and the stirring device 23 is turned on for stirring and mixing. The temperature sensor monitors the temperature in the reaction chamber 201, and the temperature threshold is set according to the optimal reaction temperature of the active bacteria. If the real-time monitoring temperature is lower than the threshold, the constant temperature control system 3 and the electric heating wire 24 are started at the same time, wherein the constant temperature control system 3 heats the water in the water tank 41, the electric heating wire 24 heats the biochemical reaction box 2, and the first water spraying device 5 sprays the hot water in the water tank 41 into the reaction chamber 201 through the water pump 42 to increase the temperature; if the real-time monitoring temperature is higher than the threshold, only the constant temperature control system 3 is turned on, the constant temperature control system 3 cools the water in the water tank 41, and the first water spraying device 5 sprays the cold water in the water tank 41 into the reaction chamber 201 through the water pump 42 to cool it. When the real-time monitoring temperature is within the threshold range, the temperature increase or temperature reduction control is stopped. When the food waste is biochemically degraded, the stirring device 23 maintains uniform stirring throughout the process. The wastewater generated in the reaction chamber 201 is filtered into the wastewater tank 7 through the filter hole 202, and then discharged out of the equipment through the outlet of the wastewater tank 7 for wastewater treatment; at the same time, the filter hole 202 is sprayed regularly through the second water spray device 6 to remove the residue accumulated in the filter hole 202.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
