Description

Technical Field

[0001] The present invention relates to the technical field of excrement and urine fermentation, and in particular to a combined excrement and urine fermentation device. Background Art

[0002] As the core device for the resource treatment of organic waste, feces and urine fermentation equipment is widely used in agriculture, animal husbandry and environmental protection. Traditional fermentation equipment mostly adopts a fixed integrated structure, and its volume and processing capacity are limited at the beginning of the design, making it difficult to flexibly adjust the scale according to actual needs. When the processing volume increases, it is necessary to replace the equipment as a whole or repeat investment in construction, resulting in high costs and low space utilization. In addition, most existing equipment uses a fixed oxygen-enhancing structure (such as a built-in aeration pipe or a static ventilation layer). Although this type of design can provide basic oxygen supply, it is easy to cause blockage due to material accumulation or microbial film adhesion after long-term operation, and it is difficult to disassemble and maintain, which directly affects the fermentation efficiency and stability.

[0003] In the fermentation process, the uniform distribution and continuous supply of oxygen are the key to ensuring the activity of aerobic microorganisms and shortening the fermentation cycle. However, the traditional oxygenation mechanism is welded or fixedly connected to the tank body, and maintenance requires shutdown and cleaning of the entire fermentation chamber, which is complicated to operate and affects continuous production. At the same time, fixed-volume equipment is difficult to adapt to the manure and urine treatment needs of different scales, especially in small and medium-sized farms or seasonal production fluctuations. Equipment is prone to idleness or overload. Therefore, there is an urgent need for a fermentation equipment that can be modularly assembled, flexibly expandable in volume, and easy to maintain, so as to achieve efficient oxygenation and long-term stable operation through structural innovation. Summary of the invention

[0004] In order to solve the technical problems raised in the background technology, the present invention provides a combined feces and urine fermentation equipment.

[0005] The present invention is implemented by the following technical scheme: a combined feces and urine fermentation equipment, which is composed of a plurality of stacked unit fermentation boxes, and the top of each unit fermentation box is open, the bottom of the unit fermentation box is provided with a slag discharge port, and the outer walls of the unit fermentation box are respectively provided with annular lower outer bosses and upper outer bosses.

[0006] A locking groove is arranged on the top surface of the unit fermentation box, and a docking portion which can be plugged into the locking groove extends from the bottom of the shell of the unit fermentation box.

[0007] Adjacent unit fermentation boxes are connected via a locking mechanism.

[0008] Furthermore, the top of the fermentation box is cylindrical, the bottom of the fermentation box is conical, and a plurality of connection holes are circumferentially distributed on the lower outer boss and the upper outer boss, and the connection holes are used to install the locking mechanism.

[0009] Through the above solution, it is convenient to assemble multiple unit fermentation boxes for expansion according to actual conditions.

[0010] Furthermore, the locking mechanism includes a connecting screw rod passing through the lower outer boss and the upper outer boss, and locking nuts are spirally installed at both ends of the connecting screw rod, so as to facilitate the assembly and fixation of two adjacent unit fermentation boxes.

An air intake pipe connected to the placement ring is also inserted on the unit fermentation box, and the other end of the air intake pipe is connected to an external oxygen supply device.

[0015] External oxygen supply equipment is used to deliver fresh air to the fermentation box to facilitate the fermentation of feces inside. Since the oxygen supply mechanism includes a plurality of air-permeable rods distributed in the unit fermentation box, air can be delivered to various positions in the unit fermentation box, thereby making the fermentation more complete and improving the efficiency.

[0016] Furthermore, the placement ring is placed on the upper surface of the inner boss and is detachably connected to the inner boss via bolts, so as to facilitate quick disassembly and assembly of the oxygen supply mechanism.

[0017] Furthermore, a top plate may be provided in the unit fermentation box, a interlayer may be provided in the top plate, a plurality of waste gas collection holes may be provided on the bottom surface of the top plate, a connecting hole connected to the interlayer may be provided on the side of the top plate, and an air outlet pipe may be inserted into the unit fermentation box, one end of the air outlet pipe is connected to the connecting hole, and the other end of the air outlet pipe is connected to an air suction device for discharging waste gas generated by fermentation.

[0018] The above mechanism can facilitate the collection of waste gas generated by fermentation. Collecting the waste gas can effectively improve the surrounding air environment and make it healthier and more environmentally friendly.

[0019] Furthermore, the top of the air rod is open, and the top movable sleeve of the air rod is provided with a connecting sleeve.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0035] Embodiment 1:

[0036] Please combine Figure 1-Figure 8 The combined feces and urine fermentation equipment of this embodiment is composed of a plurality of stacked unit fermentation boxes 1, and the top of each unit fermentation box 1 is open, and the bottom of the unit fermentation box 1 is provided with a slag discharge port 103, and the outer wall of the unit fermentation box 1 is respectively provided with a ring-shaped lower outer boss 101 and an upper outer boss 102.

[0037] A locking groove 104 is provided on the top surface of the unit fermentation box 1 , and a docking portion 105 that can be plugged into the locking groove 104 extends from the bottom of the shell of the unit fermentation box 1 .

[0038] Adjacent unit fermentation boxes 1 are connected via a locking mechanism.

[0039] In this solution, the top of the fermentation box 1 is cylindrical, the bottom of the fermentation box 1 is conical, and a plurality of connection holes are circumferentially distributed on the lower outer boss 101 and the upper outer boss 102, and the connection holes are used to install the locking mechanism. The number and diameter of the connection holes vary according to the volume of the unit fermentation box. If the volume of the unit fermentation box is larger, the number and diameter of the connection holes are larger, so as to make the connection more stable. Adjacent unit fermentation boxes 1 are connected by a locking mechanism, so that it is convenient to assemble multiple unit fermentation boxes 1 for expansion according to actual conditions, so as to ferment more animal excrement.

[0040] As an optional embodiment of the present invention, the locking mechanism includes a connecting screw 2 passing through the lower outer boss 101 and the upper outer boss 102, and locking nuts 3 are screwed on both ends of the connecting screw 2.

The inner boss 106 can be further conveniently installed to further facilitate the installation of the oxygen supply mechanism, and the modularly designed oxygen supply mechanism can be easily disassembled to facilitate later replacement and maintenance. The height of the inner boss 106 determines the installation position of the oxygen supply mechanism, and the inner boss 106 can be set at one-third of the depth of the unit fermentation box.

Since the oxygen supply mechanism includes a plurality of air-permeable rods 4 distributed in the unit fermentation box, air can be delivered to various positions in the unit fermentation box, thereby making the fermentation more complete and improving the efficiency.
