Description

Technical Field

[0001] The utility model belongs to the technical field of rural sewage treatment, and particularly relates to a box bottom plate of a modular humus filler biological filter tank. Background Technique

[0002] The rural domestic sewage treatment modes are usually divided into the following three categories: town centralized (large centralized), village centralized (small centralized), and household decentralized (scattered). Among them, the village centralized and household decentralized modes are the most widely used. However, there are many problems in the construction process, such as wide distribution, complex terrain conditions, and complex construction boundary conditions.

[0003] Chinese Patent ZL202310501162.2 discloses a modular humus filler biological filter tank and a sewage treatment system and method using the same. The modular humus filler biological filter tank includes a water distribution layer, a filter tank layer, and a water collection layer that are arranged from top to bottom and communicate with each other. The water distribution layer, the filter tank layer, and the water collection layer are all independent boxes. The box includes a pull rod, a B column, a central pipe, an A column, a side plate, and a bottom plate. A columns and B columns are fixedly erected at the four corners and four sides of the bottom plate, and side plates are arranged between the A columns and B columns. This solution realizes the rapid installation and maintenance of equipment under the limited conditions of agricultural machinery through modular and lightweight design, and solves the problems encountered in the construction process of traditional treatment facilities. However, the box bottom plate used in this solution is fixed on the pins at the bottoms of the A columns, B columns, and side plates. When the load in the box is large, the force at the pins is too large, and problems such as structural cracking and downward displacement of the bottom plate are likely to occur. At the same time, the box bottom plate lacks restraint on the square structure surrounded by the A columns, B columns, and side plates. After the filler is loaded, the top of the box is likely to explode outward, and metal pull rods are needed for restraint, increasing the equipment cost and the filling and replacement of the filler. Therefore, it is necessary to optimize the design of the above box bottom plate to solve the existing problems. Summary of the Invention

[0004] Aiming at the problems that the box bottom plate of the existing modular humus filler biological filter tank is prone to deformation and displacement and cannot restrain the square box, the purpose of the utility model is to provide a new box bottom plate suitable for the modular humus filler biological filter tank, realizing the rapid positioning and restraint of the A columns, B columns, and side plates during assembly, and having a higher load and being not easily deformed during the hoisting and operation of the box.

[0005] In order to solve the above problems, the technical solutions adopted by the utility model are as follows:

[0006] The bottom plate of the modular humus filler biological filter tank, the bottom plate of the tank body includes a bottom plate body and an insertion plate groove, a central pipe socket, a back restraint frame, a reinforcing rib, and a water permeable hole provided on the bottom plate body; the insertion plate groove is located on the front of the bottom plate body, and is a square groove formed at an equal distance parallel to the four sides of the bottom plate body and around the center of the bottom plate body, with the same width as the side plate of the tank body, for positioning and restraining the side plates, A-columns, and B-columns inserted into the modular humus filler biological filter tank; the central pipe socket is located at the center of the bottom plate body, and includes an upper socket located on the front of the bottom plate body and a lower socket located on the back of the bottom plate body; the back restraint frame is located on the back of the bottom plate body, and the outer dimensions of the back restraint frame are the same as those of the insertion plate groove, realizing the restraint of the upper parts of the side plates, A-columns, and B-columns of the lower tank body.

[0030] Embodiment 1

[0031] The bottom plate of the box body of the modular humus filler biological filter in this embodiment is a square plate formed by molding recycled plastic, and includes a bottom plate body, a plug-in slot 1, a central pipe socket 6, a back restraint frame 10, a reinforcing rib 11, and a water-permeable hole 12;

[0032] Among them, the plug-in slot 1 is located on the front surface of the bottom plate body, and is a square groove formed by being equidistant and parallel to the four sides of the bottom plate body and surrounding the center. The width of the groove is equal to the width of the box body side plate of the modular humus filler biological filter, and is mainly used to position and restrain the inserted box body side plate. Of course, it also includes positioning the A-pillars and B-pillars between the side plates.

[0033] The plug-in slot 1 is also provided with an A-pillar through-hole 2, a B-pillar through-hole 3, a drainage and ventilation through-hole 4, and a glue-applying section 5. The A-pillar through-hole 2 is located at the four vertices of the plug-in slot 1, and the B-pillar through-hole 3 is located at the midpoints of the sides of the plug-in slot 1. The shapes of the A-pillar through-hole 2 and the B-pillar through-hole 3 are respectively the same as the cross-sections of the A-pillar and the B-pillar, and are used to position and restrain the inserted A-pillar and B-pillar.

[0034] The size and position of the drainage and ventilation through-hole 4 correspond to the drainage and ventilation through-holes of the box body side plate.

[0035] The glue-applying section 5 is located on both sides of the top of the plug-in slot 1. After the box body side plate and the A-pillar and B-pillar are inserted into the plug-in slot 1, glue is applied at the glue-applying section 5 for reinforcement and sealing.

[0036] Among them, the central pipe socket 6 is located at the center of the bottom plate body, and includes an upper socket 7 and a lower socket 8. The upper socket 7 is located on the front surface of the bottom plate body, and its diameter is the same as the outer diameter of the central pipe, and is used to position and restrain the inserted central pipe.

[0037] The lower receiving interface 8 is located on the back surface of the bottom plate body. The lower receiving interface 8 from top to bottom is respectively a socket body and an annular section 9. When two boxes are docked and installed up and down, the central pipe of the lower box enters the socket body along the guidance of the annular section 9 and is restricted by the socket body, so that the central pipe of the lower box is connected and fixed to the lower receiving interface 8.

[0038] Among them, the back restraint frame 10 is located on the back surface of the bottom plate body and is a ring-shaped rib structure. The outer dimension of the back restraint frame 10 is the same as that of the insertion plate groove 1. When two boxes are docked and installed up and down, the square structure formed by the A-column, B-column and side plates in the lower box just fits into the back restraint frame 10 of the upper box. That is, the back restraint frame 10 in this embodiment can replace the restraint function of the metal cross tie rod in the original scheme.

[0039] Among them, the reinforcing ribs 11 are located on the back surface of the bottom plate body, arranged equidistantly in a crisscross pattern. The bottom height of the reinforcing ribs 11 is slightly higher than the bottom of the back restraint frame 10, which is used to reduce the self-weight while ensuring the overall strength of the box bottom plate.

[0040] Among them, the water permeable holes 12 are distributed at the center of the square frame formed by the vertical and horizontal reinforcing ribs 11. The lower part of the water permeable holes 12 penetrates the back surface of the bottom plate body, and there is a certain distance between the upper part of the water permeable holes 12 and the front surface of the bottom plate body.

[0041] When the box bottom plate is used for a water distribution tank (the box of the water distribution layer) or a water collection tank (the box of the water collection layer), the water permeable holes 12 do not need to be drilled through for water storage; when the box bottom plate is used for a packing filter tank (the box of the filter layer), the water permeable holes 12 are drilled through the front surface of the bottom plate body, so that water can flow evenly to the next layer of boxes through the water permeable holes 12.
