Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a biological filling box of sewage treatment equipment. Background Art

[0002] The biological filler box is a type of sewage treatment equipment, mainly used for filler suspension and microbial biofilm formation in biological treatment processes. The biological filler box is usually made of corrosion-resistant and high-strength materials such as plastic, fiberglass, and stainless steel. The shape is mostly rectangular or cylindrical, and the inside is filled with fillers of different materials and shapes. The material and shape of the filler have a great influence on the effect of biological biofilm formation. Commonly used fillers include plastic, ceramics, activated carbon, etc., and the shapes include spherical, cylindrical, annular, etc. The higher the surface roughness of the filler, the more conducive it is to the attachment and growth of microorganisms.

[0003] After searching, the applicant discovered that a Chinese patent disclosed an “integrated sewage treatment equipment biological filler box”, and its publication (announcement) number is “CN 219098902 U”. This patent mainly facilitates the replacement and maintenance of the biological filler in the filler box by setting up an installation frame, a fixing groove, a spring, a fixing block, a disassembly rod, a connecting rod and an inner recessed handle. However, this device is only convenient to use when only one biological filler is set in the biological filler box. If multiple biological fillers are set in the biological filler box, it is necessary to take out the filler boxes with a single biological filler one by one and then replace the biological filler. It is inconvenient to take out multiple filler boxes at the same time, and the operation is cumbersome, which reduces the convenience of the equipment. To this end, we propose a biological filler box for sewage treatment equipment. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] A biological stuffing box for sewage treatment equipment comprises a box body with a fan-shaped cross section, a water inlet pipe fixedly connected to the top surface of the box body, a water outlet pipe fixedly connected to the bottom surface of the box body, a fixed pipe rotatably connected to the right side of the lower side of the inner wall of the box body, the upper end of the fixed pipe passes through the upper side of the inner wall of the box body and extends to its top surface, a plurality of fan-shaped frames are rotatably connected to the fixed pipe, a support net is fixedly connected to the lower side of the inner wall of the fan-shaped frame, and a limit device with a variable covering range is provided on the inner wall of the fixed pipe. When the biological stuffing in the biological stuffing box needs to be replaced, after opening the sealing plate, if only one of the biological stuffings needs to be replaced, the fan-shaped frame where the biological stuffing is placed can be directly pulled out, thereby facilitating the removal of the biological stuffing inside.

[0006] Furthermore, the limiting device includes a screw rod rotatably connected to the lower side of the inner wall of the fixed tube, the upper end of the screw rod penetrates the upper side of the inner wall of the fixed tube and extends to its upper end, the rod wall of the screw rod is threadedly connected with a plurality of conical blocks, a plurality of conical blocks are provided with limiting grooves on the left sides, the inner walls of the plurality of limiting grooves are slidably connected with limiting blocks, the left sides of the plurality of limiting blocks are fixedly connected with extrusion blocks, and the left sides of the plurality of extrusion blocks penetrate the left side of the inner wall of the fixed tube and extend to its left side.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] The device's "front, back, left, right" viewing angles are Figure 1 The directions in the attached drawings are taken as reference.

[0024] like Figure 1-5As shown, a biological filler box for sewage treatment equipment includes a box body 1 with a fan-shaped cross section, a water inlet pipe 10 is fixedly connected to the top surface of the box body 1, a water outlet pipe 11 is fixedly connected to the bottom surface of the box body 1, and a fixed pipe 2 is rotatably connected to the right side of the lower side of the inner wall of the box body 1. Because the fixed pipe 2 and the box body 1 are movably connected, when only one biological filler needs to be replaced, the other hand can be used to limit the fixed pipe 2 during the process of pulling the fan-shaped frame 3 to prevent other fan-shaped frames 3 from following the displacement. When multiple biological fillers need to be replaced, the other hand can be used to limit the upper end of the fixed pipe 2 when the handle 12 is turned, so that To assist the rotation of the screw 5, the upper end of the fixed pipe 2 passes through the upper side of the inner wall of the box body 1 and extends to its top surface. A plurality of fan-shaped frames 3 are rotatably connected to the fixed pipe 2. A support net 4 is fixedly connected to the lower side of the inner wall of the fan-shaped frame 3. The biological filler is arranged in the fan-shaped frame 3 and supported by the support net 4 without hindering the filtering effect of the sewage. A limit device with a variable covering range is arranged on the inner wall of the fixed pipe 2. The limit device includes a screw 5 rotatably connected to the lower side of the inner wall of the fixed pipe 2. The upper end of the screw 5 passes through the upper side of the inner wall of the fixed pipe 2 and extends to its upper end. The rod wall of the screw 5 is threadedly connected with a plurality of conical blocks 6. The left side of each conical block 6 is provided with a limiting groove 7, and the inner walls of the plurality of limiting grooves 7 are slidably connected to the limiting blocks 8. The limiting grooves 7 and the limiting blocks 8 limit the rotation of the conical block 6, so that the conical block 6 can only move up and down. Because the surface of the conical block 6 is inclined, it can drive the extrusion block 9 to shift horizontally during its up and down movement. The left sides of the plurality of limiting blocks 8 are fixedly connected with the extrusion block 9, and the left sides of the plurality of extrusion blocks 9 penetrate the left side of the inner wall of the fixed tube 2 and extend to its left side. When the biological filler in the biological filler box needs to be replaced, after opening the sealing plate 16, if only one of the biological fillers needs to be replaced Filler, the fan-shaped frame 3 placing the biological filler can be directly pulled out, so as to facilitate the removal of the biological filler. If all or multiple biological fillers need to be replaced, the handle 12 is turned, and the handle 12 drives the conical block 6 to move the extrusion block 9 through the screw 5, so that the extrusion block 9 squeezes and fixes all the fan-shaped frames 3, so that the fan-shaped frames 3 are fixed on the fixed tube 2. At this time, pulling one of the fan-shaped frames 3 to rotate can drive all the fan-shaped frames 3 to rotate and pull them out from the box body 1, thereby reducing the cumbersome operation when replacing multiple biological fillers and facilitating use.

[0025] like Figure 1-4As shown, in some embodiments, a handle 12 is fixedly connected to the upper end of the screw rod 5, and a plurality of support bars 13 are fixedly connected to the inner wall of the box body 1 on one side of its arc surface, and the upper surfaces of the plurality of support bars 13 are respectively in contact with the bottom surfaces of the corresponding fan-shaped frames 3, and the top surfaces of the support bars 13 are frosted, thereby increasing the friction between the support bars 13 and the fan-shaped frames 3 to prevent other fan-shaped frames 3 from rotating when a single fan-shaped frame 3 is extracted. A plurality of support legs 14 are fixedly connected to the bottom surface of the box body 1, and the handle 12 facilitates the rotation of the screw rod 5, which is helpful for the use of the equipment. The support effect of the support bars 13 on the fan-shaped frames 3 enhances the stability and firmness of the equipment and improves the quality of the equipment. The support legs 14 make the equipment more stable during use and improve the safety of the equipment.

[0026] like Figure 3-5 As shown, in some embodiments, a sealing block 15 is provided at the opening of the box body 1, a sealing plate 16 is fixedly connected to the front of the sealing block 15, and the rear of the sealing plate 16 is in contact with the front of the box body 1, and L-shaped clamps 17 are fixedly connected to the left and right sides of the box body 1, and the inner walls of the multiple clamps 17 are commonly provided with I-shaped plugs 18, and the sealing block 15 is made of rubber. The sealing block 15 is placed at the opening of the box body 1 and the plug 18 is inserted into the clamp 17 to squeeze the sealing block 15. Because the sealing block 15 is made of rubber, it has a certain elastic sealing effect, and the sealing block 15 is actually larger than the volume of the opening of the box body 1, so that when squeezed, the opening of the box body 1 can be sealed to prevent sewage from leaking.
