Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a box-type wastewater treatment device. Background Technology

[0002] Wastewater treatment equipment refers to a type of environmental protection equipment used to physically, chemically, and biologically treat domestic sewage, industrial wastewater, or similar wastewater to remove pollutants (such as suspended solids, organic matter, nitrogen, phosphorus, pathogens, etc.) and bring them up to meet discharge standards or reuse requirements. This type of equipment is widely used in urban wastewater treatment plants, residential communities, industrial parks, hospitals, schools, tourist attractions, and decentralized rural wastewater treatment.

[0003] In existing technologies, multiple processing units are typically integrated into one or more enclosures, which gives them advantages such as easy installation, small footprint, and high degree of automation, making them suitable for small and medium-sized sites.

[0004] To save ground space, protect equipment, and beautify the environment, wastewater treatment equipment is typically a box-type structure, often installed using a pre-embedded method. Pre-embedded methods are mainly divided into two types: fully pre-embedded and semi-pre-embedded. Fully pre-embedded equipment places the entire unit underground, leaving only the manhole cover above ground. While this maximizes the use of surface space, it requires re-excavation for equipment failure repair or replacement, resulting in high maintenance costs and operational difficulties. Semi-pre-embedded equipment, on the other hand, places part of the equipment above ground. After installation, the box is usually directly fixed in a concrete pit, with the gap between the box and the pit wall compacted with backfill. While this reduces the difficulty of replacement to some extent, problems remain when disassembly, maintenance, or component replacement, such as limited operating space, difficulty in lifting, and potential damage to the surrounding backfill and structure. This is especially true when multiple boxes are combined, making overall lifting difficult and hindering rapid maintenance. Summary of the Invention

[0005] In view of this, the present invention proposes a box-type sewage treatment equipment that can maintain stable installation and is easy to disassemble and maintain, thereby improving the ease of use of sewage treatment equipment.

[0006] The technical solution of this invention is implemented as follows: This invention provides a box-type sewage treatment device, including a base, two clean water tanks, an intermediate tank, and a raised edge. The clean water tanks are fixedly mounted on the base for purifying sewage. The intermediate tank is abutted between the two clean water tanks and is detachably fixedly connected to them. The intermediate tank contains a heating device, an air supply device, and a water driving device. These devices are all connected to the two clean water tanks to heat, supply air, and drive the water within them. The raised edge is fixedly mounted on the side of each clean water tank away from the intermediate tank, for engaging with the backfill soil in a concrete pit. The distance between the two clean water tanks is adjustable; when the intermediate tank is removed, the two clean water tanks move closer together, causing the raised edge to separate from the backfill soil.

[0007] Based on the above technical solutions, preferably, neither end of the intermediate box extends beyond the side wall of the water purification tank.

[0008] Based on the above technical solution, preferably, it also includes two baffles, which are located at both ends of the intermediate box and fixedly connected to the water purification tank. The baffles are flush with the side wall of the water purification tank to prevent backfill soil from entering between the two water purification tanks when the intermediate box is disassembled.

[0009] Based on the above technical solutions, preferably, the baffle includes a first folding plate and a second folding plate, the first folding plate and the second folding plate are respectively rotatably disposed on the two water purification tanks and abut against the intermediate tank, and the first folding plate and the second folding plate are rotatably connected.

When the intermediate box is lifted, a portion of the elastic seat extends between the two water purification tanks and abuts against the first folding plate and the second folding plate.

[0011] Based on the above technical solutions, preferably, the elastic seat includes a base plate, a top plate, and multiple springs. The base plate is fixedly mounted on the base. The top plate is spaced above the base plate and abuts against the bottom side of the intermediate box. The springs are abutted between the top plate and the base plate. When the intermediate box is lifted, the top plate rises and abuts against the first folding plate and the second folding plate.

[0012] Based on the above technical solutions, preferably, the elastic seat further includes a pull rope, the two ends of which are fixedly connected to the top plate and the intermediate box respectively, and the pull rope passes through the base and is slidably connected to the base, and the position on the base connected to the pull rope is located below the intermediate box.

[0013] Based on the above technical solutions, preferably, a reinforcing frame is also included, which is fixedly mounted on the protruding edge and fixedly connected to the side wall of the water purification tank.

[0014] Based on the above technical solution, preferably, the water purification tank has multiple raised edges on its periphery, and the multiple raised edges are parallel and spaced apart; the reinforcing frame includes a central rod, two clamping seats, a sliding seat, and a welding plate, and the central rod is disposed between two adjacent raised edges; the two clamping seats are threadedly connected to both ends of the central rod and abut against the raised edges; the sliding seat is slidably disposed on the central rod; the welding plate is fixedly disposed on the sliding seat and fixedly connected to the periphery of the water purification tank.

[0015] Based on the above technical solutions, preferably, the top of the water purification tank and the intermediate tank extends beyond the top side of the backfill soil, and connecting joints are provided on the top of the side of the water purification tank away from the intermediate tank, the top side of the water purification tank, and the top side of the intermediate tank.

[0016] The box-type sewage treatment equipment of the present invention has the following advantages over the prior art:

[0018] (2) By installing the equipment that drives, heats and supplies air to the water in the water tank in the intermediate box, not only can the heat source, air source and drive source be fully utilized to improve the integration of the device, but also the core components can be protected and the core components can be easily maintained, thus extending the service life of the device.

[0019] (3) By setting up baffles, the impact of backfill collapse on sewage treatment equipment can be reduced; by setting up elastic seats, the structural stability of baffles can be improved; by setting up reinforcement frames, the stress uniformity of sewage treatment equipment can be improved, and the service life of the equipment can be further extended.

Detailed Implementation

[0031] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] The present invention provides a box-type sewage treatment device, comprising a base 1, two clean water tanks 2, an intermediate tank 3, a raised edge 4, a baffle 5, an elastic seat 6, and a reinforcing frame 7.

[0033] To enhance equipment stability, protect it from external environmental influences, save ground space, and beautify the environment, wastewater treatment equipment is typically pre-buried underground. There are two pre-buried methods for wastewater treatment equipment: one is full pre-buried, where the entire main structure of the wastewater treatment equipment is located underground. From the outside, only one or a few manhole covers are usually visible, and the ground can be completely restored to green space, parking lots, roads, etc.; the second is semi-pre-buried, where part of the main structure of the wastewater treatment equipment is underground, and the other part is exposed above ground. Typically, an equipment room is built on the ground or protected by railings.

[0034] While fully pre-buried wastewater treatment equipment can maximize the use of ground space, subsequent troubleshooting and equipment replacement are very difficult, usually requiring large machinery to excavate again, which greatly increases the operation and maintenance costs of wastewater treatment equipment. Therefore, semi-pre-buried wastewater treatment equipment is more widely used.

[0035] like Figure 2 As shown, firstly, excavate the soil at the installation location of the sewage treatment equipment and pour a concrete pit 8. Then, install the sewage treatment equipment in the concrete pit 8, so that the lower half of the sewage treatment equipment is located in the concrete pit 8 and the upper half of the sewage treatment equipment is located above the concrete pit 8. Finally, fill the gap between the concrete pit 8 and the sewage treatment equipment with soil and compact the soil to form backfill 9, thereby strengthening the fixation of the sewage treatment equipment.

[0036] Both the water purification tank 2 and the intermediate tank 3 extend above the top of the backfill 9. Connecting joints 201 are provided on the top of the side of the water purification tank 2 away from the intermediate tank 3, on the top side of the water purification tank 2, and on the top side of the intermediate tank 3. The connecting joints 201 are used to connect the two water purification tanks 2 and the intermediate tank 3 with the water purification tank 2.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, the water purification tank 2 is fixedly mounted on the base 1, and the intermediate tank 3 is abutted between the two water purification tanks 2 and is detachably fixedly connected to the water purification tanks 2. The water purification tank 2 is provided with multiple cavities for purifying sewage, such as sedimentation chambers and aeration chambers. The intermediate tank 3 is provided with heating equipment, air supply equipment and water driving equipment. The heating equipment, air supply equipment and water driving equipment are all connected to the two water purification tanks 2. The heating equipment heats the water in the water purification tank 2 to a specified temperature. The air supply equipment supplies oxygen to the water in the water purification tank 2. The driving equipment is used to circulate the water in the water purification tank 2, so that the water passes through each water purification cavity in the water purification tank 2 in sequence.

[0038] Both water purification tanks 2 require heating equipment, air supply equipment, and water driving equipment. Placing the intermediate tank 3 between the two water purification tanks 2 can improve the integration of the heating equipment, air supply equipment, and water driving equipment with the water purification tanks 2, and increase the heat source utilization rate of the heating equipment.

[0039] like Figure 2 As shown, the protruding edge 4 is fixedly installed on the side of the water purification tank 2 away from the intermediate tank 3. The protruding edge 4 extends out of the side wall of the water purification tank 2 and is engaged with the backing soil 9, thereby improving the fixation firmness and anti-shaking performance of the water purification tank 2.

[0040] The water purification tank 2 is fixedly connected to the base 1 by bolts and other connecting components. When the connecting components between the water purification tank 2 and the base 1 are removed, the water purification tank 2 can slide on the base 1, thereby adjusting the distance between the two water purification tanks 2.

[0041] When maintaining wastewater treatment equipment, such as Figure 3 As shown, first remove the intermediate box 3, then move the two clean water tanks 2 closer to each other, so that the convex edge 4 can be separated from the backfill 9, thus making it easier to remove the remaining components of the sewage treatment equipment from the concrete pit 8 and improving the maintenance convenience of the sewage treatment equipment.

[0042] like Figure 1 and Figure 4 As shown, the length of the intermediate box 3 is less than the length of the clean water tank 2, and neither end of the intermediate box 3 extends beyond the side wall of the clean water tank 2, so that the two ends of the intermediate box 3 do not come into contact with the backfill soil 9, thereby improving the ease of disassembly of the intermediate box 3.

[0043] When the fill soil 9 is loose or water flows into the fill soil 9, the fill soil 9 is prone to collapse, which will come into contact with the intermediate box 3. At the same time, when the intermediate box 3 is removed, some of the fill soil 9 moves between the two clean water tanks 2, which hinders the movement of the two clean water tanks 2.

[0044] like Figure 4As shown, there are two baffles 5, which are located at both ends of the intermediate tank 3, and each baffle 5 is connected to the two water purification tanks 2. The side of the baffle 5 away from the intermediate tank 3 is flush with the side wall of the water purification tank 2.

[0045] When the sewage treatment equipment is installed, the baffle 5 can prevent the backfill 9 from contacting the intermediate tank 3. After the intermediate tank 3 is dismantled, the baffle 5 can prevent the backfill 9 from collapsing between the two clean water tanks 2 and affecting the movement of the clean water tanks 2.

[0046] In order to protect the intermediate tank 3 with the baffle 5 and to prevent the baffle 5 from affecting the movement of the water purification tank 2, the baffle 5 is configured to include a first folding plate 51 and a second folding plate 52. The first folding plate 51 and the second folding plate 52 are respectively rotatably mounted on the two water purification tanks 2 and abut against the intermediate tank 3, and the first folding plate 51 and the second folding plate 52 are rotatably connected to each other.

[0047] like Figure 5 As shown, when the sewage treatment equipment is in the installation state, the first folding plate 51 and the second folding plate 52 are both in contact with the intermediate box 3, and the side of the first folding plate 51 away from the intermediate box 3 and the side of the second folding plate 52 away from the intermediate box 3 are both flush with the side wall of the clean water tank 2. This not only prevents the filler soil 9 from entering between the two clean water tanks 2, but also prevents the filler soil 9 from contacting the intermediate box 3.

[0048] like Figure 6 As shown, after the intermediate box 3 is disassembled, when the two clean water tanks 2 are moved towards each other using the telescopic device, the first folding plate 51 and the second folding plate 52 rotate and combine to form a V shape, which can prevent a large amount of fill soil 9 from moving between the two clean water tanks 2.

[0049] When the wastewater treatment equipment is in the installation state, both the first folding plate 51 and the second folding plate 52 are in contact with the intermediate box 3. However, the wastewater treatment equipment has a certain height. During the lifting of the intermediate box 3, the upper ends of the first folding plate 51 and the second folding plate 52 can abut against the side wall of the intermediate box 3, but their lower ends lack support and are prone to bending. The elastic seat 6 is used to solve the problem of bending of the first folding plate 51 and the second folding plate 52 during the lifting of the intermediate box 3.

[0050] The elastic seat 6 is fixedly mounted on the base 1. For example... Figure 7 As shown, when the intermediate box 3 is fixedly installed between the two clean water tanks 2, the bottom side of the intermediate box 3 abuts against the top side of the elastic seat 6. At this time, the intermediate box 3 abuts against the upper and lower ends of the first folding plate 51 and the second folding plate 52; Figure 8As shown, when the intermediate box 3 is lifted, the bottom side of the intermediate box 3 separates from the elastic seat 6. At this time, the elastic seat 6 extends upward into the space between the two clean water tanks 2 and abuts against the first folding plate 51 and the second folding plate 52, thereby supporting the first folding plate 51 and the second folding plate 52 and preventing the first folding plate 51 and the second folding plate 52 from bending due to the pressure of the backfill soil 9.

[0051] The elastic seat 6 includes a base plate 61, a top plate 62, multiple springs 63, and a pull rope 64. The base plate 61 is fixedly mounted on the base 1, the top plate 62 is spaced above the base plate 61, and the springs 63 are positioned between the top plate 62 and the base plate 61. Figure 7 As shown, during normal use of the sewage treatment equipment, the bottom side of the intermediate tank 3 abuts against the top side of the top plate 62, as... Figure 8 As shown, when the intermediate box 3 is lifted, the top plate 62 is raised by the elastic force of the spring 63, thereby abutting against the first folding plate 51 and the second folding plate 52, improving the structural reliability of the first folding plate 51 and the second folding plate 52.

[0052] The two ends of the pull rope 64 are fixedly connected to the top plate 62 and the middle box 3 respectively, and the pull rope 64 passes through the base 1 and is slidably connected to the base 1. The position on the base 1 where the pull rope 64 is connected is located below the middle box 3.

[0053] When the intermediate tank 3 is raised and detached from the water purification tank 2, the end of the pull rope 64 away from the top plate 62 can be moved to the outside. At this time, the pull rope 64 can be tightened by hand and the top plate 62 can be moved downward, thereby detaching the top plate 62 from the first folding plate 51 and the second folding plate 52, allowing the first folding plate 51 and the second folding plate 52 to rotate, thus avoiding obstruction to the movement of the two water purification tanks 2.

[0054] The bottom of the water purification tank 2 is tightly surrounded by the backfill soil 9, which bears a continuous and uniform static soil pressure. The water position inside the water purification tank 2 is uneven, and the inner wall of the water purification tank 2 bears uneven water pressure. Under the combined effect of these two factors, uneven stress will appear on the side wall of the water purification tank 2, which will make the water purification tank 2 prone to damage during use.

[0055] Therefore, the stress on the side wall of the water purification tank 2 was simulated and analyzed in advance. The reinforcing frame 7 was fixedly installed on the protruding edge 4, and the reinforcing frame 7 was fixedly connected to the position on the side wall of the water purification tank 2 where the stress was uneven, so as to strengthen the structural strength of the side wall of the water purification tank 2.

[0056] like Figure 1 and Figure 9As shown, the water purification tank 2 has multiple protruding edges 4 on its periphery, which are parallel and spaced apart. The reinforcing frame 7 includes a central rod 71, two clamping seats 72, a slide seat 73, and a welding plate 74. The central rod 71 is positioned between two adjacent protruding edges 4. The two clamping seats 72 are threadedly connected to both ends of the central rod 71 and abut against the protruding edges 4. The slide seat 73 is slidably mounted on the central rod 71. The welding plate 74 is fixedly mounted on the slide seat 73 and fixedly connected to the periphery of the water purification tank 2. The adjacent protruding edges 4, the central rod 71, the slide seat 73, and the welding plate 74 are used to strengthen the structural strength of the periphery of the water purification tank 2 and extend its service life.

[0057] The method of using the box-type sewage treatment equipment of the present invention is as follows:

[0058] When installing the sewage treatment equipment, the two clean water tanks 2 are fixedly connected to the base 1, and the middle tank 3 is fixed between the two clean water tanks 2. After the concrete pit 8 is constructed, the sewage treatment equipment is first placed into the concrete pit 8, then the pipeline connection is completed, and finally the backfill soil 9 is filled between the concrete pit 8 and the sewage treatment equipment.

[0059] When replacing or maintaining the sewage treatment equipment, first disassemble the connecting components between the intermediate tank 3 and the clean water tank 2, use the lifting equipment to lift and remove the intermediate tank 3, then tighten the pull rope 64 to move the top plate 62 away from the first folding plate 51 and the second folding plate 52, then use the hydraulic telescopic equipment to pull the two clean water tanks 2 to move them towards each other, thereby separating the convex edge 4 from the backfill 9, and finally use the lifting equipment to lift out the base 1 and the clean water tank 2.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
