DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those skilled in the art without any creative effort fall within the scope of protection of the present application.

[0026] Reference Figures 1-5As shown, the embodiment discloses a sludge aerobic compost pile forming device, which comprises a shell 2, the lower side of the shell 2 is provided with a plurality of support wheels 3 for facilitating movement, the shell 2 is fixedly connected by a front end plate 203, a top plate 204 and two side plates 202, and an open forming cavity is formed in the interior of the shell 2, the front end plate 203, the top plate 204 and the two side plates 202 are metal materials, and the connection mode is welding; when the sludge aerobic compost pile forming device is placed on the ground supported by the support wheels 3, the lower end of the two side plates 202 is slightly higher than the ground, so as to ensure that the shell 2 can move close to the ground and avoid the material in the forming cavity flowing out from the gap between the two side plates 202 and the ground; the two side plates 202 are in an inclined state, the distance between the two side plates 202 gradually increases from top to bottom and from back to front, so that the cross section of the forming cavity is trapezoidal and gradually shrinks from front to back; a feeding hopper 1 is fixed above the shell 2, the interior of the feeding hopper 1 is communicated with the middle front part of the forming cavity, so that the sludge material can enter the middle front part of the forming cavity through the feeding hopper 1; a traction part 5 and a plurality of winding wheels 6 are installed on the front side of the shell 2; the traction part 5 is used to be connected with a tractor or other traction equipment to provide traction power for the movement of the sludge aerobic compost pile forming device, the winding wheels 6 are rotationally connected to the shell 2, and a tensile hose 7 is wound on each winding wheel 6, the tensile hose 7 at least comprises a supply pipe 701 and a heat exchange pipe 704; a plurality of guide-in barrels 12 extending rearward in the forming cavity are fixed on the front end plate 203 of the shell 2, the guide-in barrels 12 are tubular structures and are permeable from front to back, and the front end port of the guide-in barrel 12 is communicated with the front side space of the front end plate 203; the tensile hose 7 can pass through the guide-in barrel 12.

[0027] Referring to Figure 1 、 Figure 2 、 Figure 8 As shown, when the pretreated sludge material is subjected to composting treatment, the sludge aerobic compost pile forming device can quickly and efficiently complete the stacking of the material pile. Before the material pile is stacked, according to actual production needs, a plurality of tensile hoses 7 are extended into the forming cavity or the rear of the forming cavity through the guide-in barrels 12, the sludge aerobic compost pile forming device is slowly moved by using a tractor or a winching device, and at the same time, the sludge material is put into the feeding hopper 1, under the shaping action of the forming cavity, the sludge material is stacked into a strip-shaped material pile with a trapezoidal cross section; during the stacking of the material pile, the winding wheels 6 are automatically unwound under the action of the tensile hose 7, and under the guidance of the guide-in sleeve, the tensile hose 7 will be gradually embedded in the material pile; since the tensile hose 7 has the characteristic of tensile resistance and extends linearly in the material pile, when the material pile is fully fermented, the tensile hose 7 can be pulled out of the material pile to avoid hindering the subsequent mechanical operation.

[0028] This sludge aerobic composting stack forming equipment offers a fast, efficient, and time-saving solution for stacking materials. The gradually narrowing cavity design of the forming chamber applies pressure to the surface of the stack, improving adhesion and compaction between surface materials, thus enhancing stack stability, preventing collapse, and effectively preventing the loss of moisture and heat from within the stack. This sludge aerobic composting stack forming equipment can pre-embed multiple tensile hoses 7 within the stack as needed. During composting, water, nutrient solution, chemicals, and fresh air, necessary for fermentation, can be supplied to the stack via the supply pipe 701. Cooling or heating media can also be circulated through the heat exchange pipe 704 to regulate the internal temperature of the stack, preventing excessively high or low temperatures and ensuring composting efficiency and quality. In addition, the function of the inlet tube 12 is to guide the tensile hose 7 to be buried in the material pile. Furthermore, the presence of the inlet tube 12 will cause the material pile to form a local hollow, thereby increasing the permeability inside the material pile, making the temperature of the material inside the material pile more uniform, and improving the balance of fermentation.

[0029] like Figure 1 , Figure 2 As shown, in the specific implementation process, the strength of the shell 2 can be ensured and the weight of the shell 2 can be reduced by setting the frame 201. Specifically, the shell 2 is externally fixedly connected to the frame 201 for improving its structural strength. The frame 201 is formed by welding several metal rods. Furthermore, the support wheel 3, feed hopper 1, traction part 5 and winding wheel 6 are all installed on the frame 201 to improve the connection strength between these components and the shell 2.

[0030] See Figure 1 , Figure 2 As shown, in the specific implementation process, a number of wheel seats 4 are fixedly connected to the front side of the housing 2, the winding wheel 6 is rotatably fixed on the wheel seat 4, and the winding wheel 6 is fixedly connected to a handwheel 8; the handwheel 8 can be used to manually drive the winding wheel 6 to rotate, so that when using this sludge aerobic composting stack forming equipment, the tensile hose 7 can be conveniently wound around the winding wheel 6 in advance.

[0031] See Figure 3 As shown, in the specific implementation process, a guide plate 13 is fixedly connected to the upper side of the inlet cylinder 12, and at least one end of the guide plate 13 is fixedly connected to the shell 2. Thus, the guide plate 13 and the inlet cylinder 12 can support each other and improve the structural stability. At the same time, the main function of the guide plate 13 is to guide the falling direction of the material so that the material entering from the hopper can be more evenly dispersed to the corner area of ​​the shell 2, so that the formed material stack shape is more regular and standard.

[0032] See Figure 7As shown, in the specific implementation process, two roller frames 14 are fixed at the rear end of the housing 2. Rotatable pressure rollers 15 are respectively installed on the two roller frames 14. The two pressure rollers 15 are distributed in a figure-eight shape. Elastic elements that drive the two pressure rollers 15 to move closer are installed on the two roller frames 14. Thus, as the material stack is formed, the two pressure rollers 15 can roll and press the two sides of the material stack, further improving the density and strength of the surface layer on both sides of the material stack.

[0033] See Figure 2 , Figure 6 As shown, in the specific implementation process, a limiting seat 10 is fixed at the rear end of the housing 2. The limiting seat 10 is limited by a baffle 9 that can slide up and down and a locking member 11 for locking the baffle 9. The baffle 9 is used to block the upper middle area of ​​the rear port of the housing 2. Thus, by adjusting the baffle 9 up and down, the discharge height of the rear port of the housing 2, i.e. the stack height, can be adjusted.

[0034] like Figure 4 As shown, in the specific implementation process, one end of the supply pipe 701 is provided with a connector 703 for connection to a pressure device for pumping gas or liquid, and the other end of the supply pipe 701 is a sealed end; the pipe wall of the supply pipe 701 is made of elastic material, and a slit 702 in the shape of a straight line or a cross is opened on the pipe wall; when gas or liquid is supplied to the material pile using the supply pipe 701, the high-pressure medium in the supply pipe 701 can drive the slit 702 to open and discharge into the material pile. When no supply operation is performed, the slit 702 can automatically return to the closed state, thereby preventing material from entering the supply pipe 701 and preventing pipeline blockage; at the same time, based on the above design features of the supply pipe 701, after the slit 702 returns to the closed state, the outer wall of the supply pipe 701 is relatively smooth, making it easier to pull the supply pipe 701 out of the material pile and facilitating operation.

[0035] like Figure 5 As shown, in the specific implementation process, the heat exchange tube 704 is provided with joints 703 at both ends. When stacking the material, the joints 703 at both ends of the heat exchange tube 704 are exposed at both ends of the material stack so that the heat exchange tube 704 can be connected to the pressure equipment and the heat exchange equipment to form a closed loop. Furthermore, the supply pipe 701 and the heat exchange tube 704 can be reinforced to improve tensile strength.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
