Description

Technical Field

[0001] The present invention relates to the technical field of aerobic fermentation chambers, and in particular to a modular quick-pack aerobic fermentation chamber for organic solid waste. Background Art

[0002] Aerobic fermentation is a conventional environmentally friendly treatment process for organic solid waste. Aerobic fermentation technology is stable, the process flow is simple, the operation and maintenance are convenient, there is no secondary pollution, the energy consumption is low, the operating cost is low, and the outlets for finished products are diversified. It is a solid waste disposal method recommended by the state.

[0003] During the aerobic fermentation process, in order to meet the process requirements of aerobic fermentation, the fermentation chamber is required to be a fully enclosed structure and divided into functional areas to meet the functions of sealing, insulation, external drainage, etc.

[0004] A conventional fermentation chamber includes a steel structure and an outer cover. The main structure columns are installed on anchor bolts embedded in the civil engineering. The periphery of the columns is connected to the surrounding beams with bolts. The inner side of the columns is reinforced with truss beams. The top of the columns is bolted to the rain gutter and the steel A-frame. For example, the application number: CN201710262566.5 discloses a steel structure scaffolding, which includes several steel columns. The adjacent steel columns are connected together by steel beams. Each of the steel columns is set on a support. The support is provided with embedded steel bars around the circumference of the steel column. The upper end of the embedded steel bars is also passed through the base of the steel column, and the embedded steel bars are provided with nuts above the base to make the base and the support fit tightly together. The support is provided with several baffles abutting the base along the circumference of the base. This technical solution uses a pre-buried steel bar that is partially buried underground, with the exposed portion just enough to thread the support and base together. Nuts are then used to lock the support and base together, thus securing the ground, support, and base. However, its drawback is that the lack of effective positioning of the pre-buried steel bar base leads to large errors, which can easily cause the steel column and the pre-buried steel bar base to be misaligned, causing significant inconvenience during later installation and low installation efficiency.

[0005] Conventional fermentation chambers use a herringbone frame on the roof, covered with rainproof FRP panels / sun panels, which are assembled piece by piece using self-tapping screws. After the main structure is installed, the gaps need to be sealed with foam, and insulation panels are installed on the exterior of the steel structure. While this structure meets the requirements of aerobic fermentation, it takes more than three months to install, the process is cumbersome, and the cost of the structure is high.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1:

[0049] A modular quick-install aerobic fermentation chamber for organic solid waste, comprising an integrated concrete fermentation tank 1, such as Figure 2 As shown, the integrated concrete fermentation tank 1 includes a concrete raft foundation 11, a track wall 12, and a partition wall 13. The concrete raft foundation 11 is the bottom surface, and the track wall 12 is connected on both sides thereof. Partition walls 13 are set at both ends to form a rectangular tank body for fermentation. During actual use, the fermentation raw materials are accumulated in the rectangular tank body for aerobic fermentation; an installation edge 14 for quickly fixing the dry door type module frame is set on the outside of the track wall 12.

[0050] like Figure 1As shown, a number of door-type module frames are set up in the length direction of the integrated concrete fermentation tank 1. It can be understood that as the length of the concrete fermentation tank increases or decreases, the door-type module frames can also be adjusted accordingly in number, so as to adapt to the construction or renovation of concrete fermentation tanks of different lengths. In actual use, if the fermentation tank needs to be expanded, its length can be increased at one end of the integrated concrete fermentation tank 1, and then the corresponding door-type module frame can be set up; the modular frame can adjust the number according to the length of the fermentation tank to meet the needs of fermentation tanks of various lengths. Furthermore, a number of longitudinal pull rods 5 are interspersed between the several door-type module frames; a number of fastening structures for quick connection with the longitudinal pull rods 5 are distributed on the door-type module frames; the longitudinal pull rods 5 can connect the several door-type module frames into a whole, thereby improving the firmness of the entire fermentation chamber. In actual use, the longitudinal pull rods 5 can be through all the door-type module frames from beginning to end. It can be understood that at this time the longitudinal pull rods 5 are a whole, and their fixing strength to the door-type module frames can be guaranteed, but due to their long length, they are inconvenient to install; in actual operation, the longitudinal pull rods 5 can be divided into multiple sections, and the longitudinal pull rods 5 set on the door-type module frames are fixed in sections, and the sections are staggered to increase the longitudinal pull rods 5 to connect them into a whole.

[0051] When the door-type module frame is connected and fixed with the integrated concrete fermentation tank 1, specifically, Figure 5 As shown, the concrete fermentation tank is provided with mounting rails 14 along both sides of its length for securing the column feet of the gate-type module frames. Several foundation pits 141 are distributed along the length of the mounting rails 14. The column feet are inserted into the foundation pits 141 and filled with grouting material 4; the grouting material 4 is micro-expanding fine stone concrete. The column feet of the gate-type module frames are placed in the foundation pits 141, and the grouting material 4 is poured into the gaps in the foundation pits 141 to secure the column feet. The column feet of each gate-type module frame are inserted into the foundation pits 141, and micro-expanding fine stone concrete is then poured into the gaps between the foundation pits 141 and the column feet, thereby firmly securing the column feet. Rapid pouring is used for the joints of the civil engineering connections, avoiding the inconvenience of installing pre-buried civil engineering bolts due to civil engineering errors in the prior art. Therefore, the present device improves installation efficiency. Example 2:

[0052] The lattice-type composite column 2 includes two parallel square tubes 21, with a plurality of web modules 22 evenly distributed between the two square tubes 21. The plurality of web modules 22 form a reinforcing rib portion connecting and fixing the square tubes 21 on both sides, and a fastening structure for fixing the longitudinal tie rod 5 is formed inside the web module 22.

[0053] Specifically, the fastening structure includes a U-shaped groove 221 for supporting the longitudinal rod 5, a positioning plate, and a steel bar clip 6. The longitudinal rod 5 is placed in the U-shaped groove 221. Figure 3As shown, positioning plates are provided on both sides of the U-shaped groove 221, and the steel bar clamp 6 clamps the longitudinal rod 5 in the U-shaped groove 221 and the two ends of the steel bar clamp 6 are buckled into the positioning plates for fixation; specifically, as shown in FIG. Figure 7 As shown, the web module 22 is in the shape of an isosceles trapezoid. The top and bottom of the trapezoid are welded to the square tubes 21 on both sides. A transverse plate 224 is provided along the symmetry line of the trapezoid, and the two ends of the transverse plate 224 are fixedly welded to the two square tubes 21, so that the transverse plate 224 and the two waists of the trapezoid form a stable triangular structure. Figure 6 As shown, two web modules 22 are overlapped and welded on both sides of the square tube 21, which not only firmly connects the two square tubes 21 together, but also forms a triangular stable structure with greatly improved strength. In addition, the provided transverse plate 224 is used to facilitate positioning of the longitudinal tie rod 5.

[0054] like Figure 6 、 Figure 7 As shown, the web module 22 is double-layered and clamped and welded to the outer walls of the two square tubes 21. A U-shaped groove 221 is provided on the upper edge of the horizontal plates 224 on both sides. The positioning plates on both sides of the U-shaped groove 221 are respectively a positioning vertical plate 1 222 and a positioning vertical plate 2 223; Figure 8 As shown, the steel bar clamp 6 includes an elastic portion 61, a straight arm portion 62, and a slot portion 63, and preferably, in a free state, the angle between the two straight arm portions 62 is 160°; the elastic portion 61 is in a semicircular arc shape, and the two ends of the semicircular arc are connected to straight arm portions 62 extending straight to both sides. The elastic deformation of the semicircular arc-shaped elastic portion 61 can change the angle between the straight arm portions 62 on both sides, thereby applying an extrusion and fixing force to the longitudinal pull rod 5; specifically, the outer end of the support arm portion is formed with a slot portion 63 with an opening facing upward, and the opening of the elastic portion 61 is opposite to the slot portion 63. The slot portions 63 at the ends of the two steel bar clamps 6 are connected to form a U-shaped double-clamp structure, and the elastic portion 61 is used to press on the upper side of the longitudinal pull rod 5, and the slot portions 63 on both sides are clamped on the positioning plates on both sides. During use, the longitudinal tie rod 5 is set in the U-shaped groove 221 on the web module 22, and then the slot portion 63 at one end of the steel bar clamp 6 is inserted into the bottom of the positioning vertical plate 1 2222, and then the other end is pressed downward. By utilizing the deformation of the steel bar clamp 6, the inner arc of the steel bar clamp 6 presses the longitudinal tie rod 5 while the other end is clamped at the bottom of the positioning vertical plate 223 to clamp it. When clamped, the straight arm portions 62 on both sides are 180° in shape. Example 3:

[0055] like Figure 3 、 Figure 4 As shown, the door-type module frame includes a lattice-type composite column 2 and a lattice-type scaffold 3. The lattice-type composite column 2 is vertically fixed in the foundation pit 141, and both ends of the lattice-type scaffold 3 are connected to the lattice-type composite column 2 through a plug-in structure; Figure 3As shown, the plug-in structure includes a plug-in sleeve 23; the plug-in sleeve 23 is fixedly arranged at the top end of the lattice-type combined column 2, and the lower end of the plug-in sleeve 23 is fixedly inserted into the lattice-type combined column 2, and is fixedly connected to the lattice-type combined column 2 by welding. The upper end of the plug-in sleeve 23 is inserted into the end of the lattice-type scaffolding 3, so that the lattice-type combined column 2 and the lattice-type scaffolding 3 are fixedly connected. In order to strengthen the fixing strength, a self-tapping screw 71 can be drilled from the side wall to pass through the lattice-type scaffolding 3 and the plug-in sleeve 23, which effectively prevents the plug-in from falling off and strengthens the connection effect.

[0056] Furthermore, the lattice-type scaffold 3 includes a lattice-type arched beam 31, a lower chord 32, and a web 33; the lattice-type arched beam 31 has the same structure as the lattice-type composite column, and is provided with two square tubes 21 and a web module 22 and a fastening structure between the square tubes 21, but the difference is that it is made into a herringbone structure with a raised middle portion, and the lattice-type arched beam 31 is a herringbone structure, such as Figure 4 As shown, the lower chord 32 is stretched between the two ends of the lower part of the lattice arched beam 31, and the web members 33 are continuously distributed in an M-shape in the crescent-shaped space formed between the lattice arched beam 31 and the lower chord 32.

The connecting male edge 72 is arranged on the upper edge of the thermal insulation composite wall panel 7, and the connecting female edge 73 is arranged on the lower edge thereof. When the two thermal insulation composite wall panels 7 are connected, the mutual insertion and overlap of the connecting male edge 72 and the connecting female edge 73 are used to ensure a firm connection and prevent rainwater from seeping in; the outer side of the connecting female edge 73 is provided with an overlapping edge 74, and the inner side is concave The portion 75 is provided with an inserting edge 76 on its inner bottom; a protrusion 77 is provided on the inner side of the connecting male edge 72 to cooperate with the inner recess 75, and a groove 78 is provided on the end of the protrusion 77 to cooperate with the inserting edge 76; during actual connection, when the protrusion 77 is inserted into the inner recess 75, the inserting edge 76 of the inner recess 75 is also inserted into the slot of the protrusion 77, so that a reciprocating multi-channel connecting surface is formed, which forms a labyrinth-like seal for external air or water vapor, thereby achieving a good separation effect. A stepped edge 79 is provided on the outer side of the connecting male edge, and the overlapping edge 74 covers the outer side of the stepped edge 79 to form a good joint covering effect, which is excellent for diverting rainwater or blocking wind; an accommodating space is provided on the inner wall of the overlapping edge 74 and the outer wall of the stepped edge 79, and a self-tapping screw 71 is used to pass through the protrusion 77 to fix the thermal insulation composite wall panel 7 on the dry door type module frame, and the nut of the self-tapping screw 71 is placed in the accommodating space.
