Abstract
Description
Technical Field
[0001] This utility model relates to the field of tank skin technology, and in particular to a corrosion-resistant tank skin for livestock and poultry manure fermentation equipment. Background Technology
[0002] Manure fermentation is a biological treatment technology that refers to the process of converting manure into organic fertilizer or biofuel through the fermentation of microorganisms. This process mainly involves the decomposition and transformation of organic matter by microorganisms, producing gases such as methane and carbon dioxide, while releasing energy. Therefore, livestock and poultry manure fermentation equipment made of tank shells is required.
[0003] For most existing tank shells used in livestock and poultry manure fermentation equipment, their service life can be guaranteed by the combination of various composite materials. However, for some tank shells used in livestock and poultry manure fermentation equipment, the tank shells are directly welded at the joints using relevant processes during assembly. Although this welding provides a fixing effect after assembly, the joints are often the weakest points and the fastest corroding areas. Therefore, there is an urgent need for a corrosion-resistant tank shell for livestock and poultry manure fermentation equipment. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant tank shell for livestock and poultry manure fermentation equipment, comprising a tank shell body one and a tank shell body two. The front and rear sides of the tank shell body one are respectively provided with a first groove and a second groove. A sealing groove is provided on the inner side of the tank shell body one. A sealing protrusion is bonded and installed on the inner wall of the sealing groove on the tank shell body one. The surface of the sealing protrusion is welded and installed on the surface of the tank shell body two. An internal sealing layer is fixedly installed on the inner side of the tank shell body one and the tank shell body two. An external sealing layer is welded and installed on the outer side of the tank shell body one and the tank shell body two.
[0006] Preferably, the can body includes a PP material layer, a rock wool layer, and a stainless steel layer.
[0007] Preferably, the front and rear sides of the can body two are also provided with a first groove and a second groove, and the second groove on the can body one is welded and installed with the first groove on the can body two.
[0008] Preferably, both the first and second can body bodies are provided with sealing grooves and welded with sealing protrusions, and the sealing grooves and sealing protrusions on the first and second can body bodies are staggered.
[0009] Preferably, auxiliary protrusions are welded and installed on the surfaces of both the first and second can body bodies.
[0010] Preferably, the shapes of the first and second grooves on the can body one and can body two are in an L-shape.
[0011] Preferably, the inner side of the PP material layer is fixedly installed on the outer side of the rock wool layer, and the inner side of the rock wool layer is fixedly installed on the outer side of the stainless steel layer.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) The corrosion-resistant tank of the livestock and poultry manure fermentation equipment is improved by setting an internal sealing layer and an external sealing layer at the tank body one and the tank body two, thereby improving the joint strength and anti-permeability and preventing liquid leakage from the joint. This method adopts the effect of bonding and misaligning the tank body one and the tank body two, misaligning the connection and sealing the gaps on the inside and outside, which greatly improves the sealing effect formed after the tank body one and the tank body two are assembled, greatly improves the overall corrosion resistance of the livestock and poultry manure fermentation equipment, and ensures the service life of the livestock and poultry manure fermentation equipment.
[0014] (2) The corrosion-resistant tank skin of the livestock and poultry manure fermentation equipment is bonded and installed at the second and first grooves on the tank skin body one and tank skin body two. At the same time, the staggered sealing grooves and sealing protrusions are used for staggered bonding, which ensures a good sealing effect at the gap when the tank skin body one and tank skin body two are welded later. This reduces the disadvantage of the livestock and poultry manure water accumulation and corrosion at the tank skin body one and tank skin body two, and improves the corrosion prevention effect during the fermentation of livestock and poultry manure.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0025] Please see Figure 1-4This utility model provides a technical solution: a corrosion-resistant tank shell for livestock and poultry manure fermentation equipment, comprising a tank shell body 1 and a tank shell body 2 9. The front and rear sides of the tank shell body 1 are respectively provided with a first groove 2 and a second groove 3. The front and rear sides of the tank shell body 2 9 are also provided with a first groove 2 and a second groove 3. The first groove 2 and the second groove 3 on the tank shell body 1 and the tank shell body 2 9 are L-shaped. The second groove 3 on the tank shell body 1 is welded to the first groove 2 on the tank shell body 2 9. When assembling the livestock and poultry manure fermentation equipment using the tank shell body 1 and the tank shell body 2 9, the L-shaped second groove 3 on the tank shell body 1 and the L-shaped first groove 2 on the tank shell body 2 9 form a mating fit. Then, adhesive is used for bonding, which allows the tank shell body 1 and the tank shell body 2 9 to form a preliminary positioning and has a staggered mating fit, thus ensuring the convenience of subsequent welding and fixing operations between the tank shell body 1 and the tank shell body 2 9.
[0026] Furthermore, a sealing groove 4 is provided on the inner side of the can body 1. A sealing protrusion 5 is bonded to the inner wall of the sealing groove 4 on the can body 1. The surface of the sealing protrusion 5 is welded to the surface of the can body 2 9. Both the can body 1 and the can body 2 9 have sealing grooves 4 and welding installations of sealing protrusions 5. The sealing grooves 4 and sealing protrusions 5 on the can body 1 and the can body 2 9 are staggered. By bonding and installing the second groove 3 and the first groove 2 on the can body 1 and the can body 2 9, and by using the staggered sealing grooves 4 and sealing protrusions 5 for staggered bonding, a good sealing effect is ensured at the gap when welding the can body 1 and the can body 2 9 in the future. This reduces the disadvantage of easy water accumulation of livestock and poultry manure and corrosion at the can body 1 and the can body 2 9, and improves the anti-corrosion effect during the fermentation of livestock and poultry manure.
[0027] Furthermore, auxiliary protrusions 6 are welded and installed on the surfaces of both tank body 1 and tank body 2 9. By welding and installing auxiliary protrusions 6 on the outside of tank body 1 and tank body 2 9, the disadvantage of the livestock and poultry manure fermentation equipment being damaged or squeezed during transportation is reduced. This reduces the risk of the surface of tank body 1 or tank body 2 9 being damaged and causing overall dents or bulges, thus reducing the disadvantage of easy corrosion at the damaged areas.
[0028] Furthermore, an internal sealing layer 7 is fixedly installed on the inner side of the tank body 1 and the tank body 2 9, and an external sealing layer 8 is welded and installed on the outer side of the tank body 1 and the tank body 2 9. The internal sealing layer 7 is bonded with resin and fiberglass cloth by lamination. First, unsaturated polyester resin or vinyl ester resin is applied to the joint, and then alkali-free fiberglass cloth is laid. After ensuring that the layer is tightly laid without air bubbles, the curing operation is carried out. The external sealing layer 8 is reinforced with fiberglass felt (thickness ≥ 2mm) to improve the joint strength and impermeability and prevent liquid from leaking from the joint. This method uses the bonding and misalignment of the tank body 1 and the tank body 2 9, the misalignment of the joint, and the sealing effect of the inner and outer sewing of the gaps. This greatly improves the sealing effect formed after the tank body 1 and the tank body 2 9 are assembled, greatly improves the overall corrosion resistance of the livestock and poultry manure fermentation equipment, and ensures the service life of the livestock and poultry manure fermentation equipment.
[0029] Furthermore, the tank body 2 9 includes a PP material layer 901, a rock wool layer 902, and a stainless steel layer 903. The inner side of the PP material layer 901 is fixedly installed on the outer side of the rock wool layer 902, and the inner side of the rock wool layer 902 is fixedly installed on the outer side of the stainless steel layer 903. Through the composite assembly of the PP material layer 901, the rock wool layer 902, and the stainless steel layer 903, the individual pieces of this livestock and poultry manure fermentation equipment can have good corrosion resistance.
[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
