Description

Technical Field

[0001] The present invention relates to the technical field of wastewater sedimentation, and more specifically, to a modular multi-stage sedimentation tank and an assembly method thereof. Background Art

[0002] Construction wastewater needs to be treated before being discharged into the municipal pipe network. Currently, the treatment of construction wastewater usually uses a three-stage sedimentation tank to sediment the wastewater. The three-stage sedimentation tank has two types: finished products and non-finished products. The non-finished three-stage sedimentation tank is generally made of bricks. After the project construction is completed, this type of sedimentation tank is abandoned. The finished three-stage sedimentation tank is generally made of steel plates. After the project ends, it is transported to other projects for repeated use. However, due to differences in project types, on-site process practices, water quality conditions, etc., different projects have different requirements for the specifications and sedimentation times of the sedimentation tank. The same three-stage sedimentation tank is difficult to meet the needs of different projects, and the size of the three-stage sedimentation tank is large, making transportation inconvenient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a modular multi-stage sedimentation tank and an assembly method thereof, which can be freely assembled according to the sedimentation needs of construction wastewater, greatly improving the demand for the sedimentation of construction wastewater. At the same time, it can be assembled on the construction site, making transportation more convenient, and can be stored and recycled highly after use.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The present invention will be described in detail below.

[0045] As Figures 1-7 shown:

[0046] A modular multi-stage sedimentation tank includes multiple groups of tank 1 with the same structure and connected in sequence, and tank 2 connected and communicated with tank 1;

[0047] As Figure 4 shown, the tank 1 includes a bottom plate 11, two groups of side plates 12 arranged in parallel and installed on the bottom plate, and end plates 13 located between the two groups of side plates 12 and respectively connected to the two groups of side plates 12; the end plates 13 and the two groups of side plates 12 cooperate to form a cavity 14 with an opening on the side away from the end plates 13;

[0048] In adjacent two groups of tank 1, the end plate 13 of one group of tank 1 is installed at the opening of the other group of tank 1 and cooperates to form a sedimentation cavity 10;

[0049] In adjacent two groups of tank 1 and tank 2, the tank 2 is installed at the opening of the other group of tank 1 and cooperates to form a sedimentation cavity 20.

[0050] During use, more than two sets of the first ponds 1 with the same structure are assembled, and then the last first pond 1 is assembled and connected to the second pond 2, so as to realize on-site assembly according to the sedimentation level required for construction wastewater; through the connection of multiple sets of the first ponds 1, the sedimentation requirements for construction wastewater with different sedimentation levels can be met. For example, when secondary sedimentation is required for construction wastewater, one set of the first pond 1 and one set of the second pond 2 can be used in combination to achieve tertiary sedimentation; when tertiary sedimentation is required for construction wastewater, two sets of the first ponds 1 and one set of the second pond 2 can be used in combination to achieve tertiary sedimentation; when sedimentation of four levels or above is required, more than three sets of the first ponds 1 and one set of the second pond 2 can be used in combination to achieve it; compared with the finished sedimentation tank in the prior art, it can meet the sedimentation requirements of on-site construction wastewater. Compared with the sedimentation tank constructed by on-site masonry, the present invention only needs to be assembled, with high construction efficiency and can be recycled after use, greatly saving the construction cost.

[0051] In some possible implementation manners, in order to effectively realize the connection with the first pond 1;

[0052] Such as Figure 5 As shown, the second pond 2 includes a bottom plate two 21, two groups of side plates two 22 arranged in parallel and installed on the bottom plate two 21, an end plate two 23 located between the two groups of side plates two 22 and respectively connected to the two groups of side plates two 22, and a sealing plate 24 arranged parallel to the end plate two 23 and forming a sedimentation chamber two 20; the end plate two 23 is located on the opening side of the first pond 1 connected to it.

[0053] In some possible implementation manners, in order to effectively realize the step-by-step sedimentation of construction wastewater;

[0054] The end plate one 13 has the same structure as the end plate two 23, and includes a plate body with a water passing hole 131 arranged at the top and a plug-in part 16 installed on the outer side of the plate body.

[0055] The water passing hole 131 is used for the construction wastewater in the upper-level pond to flow downward and into the pond, realizing sedimentation;

[0056] In some possible implementation manners, in order to increase the sedimentation path of construction wastewater in the sedimentation chamber one 10 or the sedimentation chamber two 20 and improve the sedimentation effect;

[0057] Each group of water passing holes 131 in the plate body is two groups and arranged in parallel, and a plug board 18 for closing the water passing hole 131 is arranged on the plate body; a slot component 17 for installing the plug board 18 and arranged in one-to-one correspondence with the water passing hole 131 is arranged on the inner side surface of the plate body.

[0058] Such as Figure 1As shown, there are two groups of water passing holes 131 on each group of plate bodies. The axes of the two groups of water passing holes 131 in all the plate bodies are on two straight lines respectively and the two straight lines are arranged in parallel. The reason for setting two groups is that when used in cooperation with the slot component 17, the opened water passing holes 131 can be arranged staggeredly, so that the sedimentation path of the construction wastewater is longer and the sedimentation effect is greatly improved. For the water passing holes 131 on the first pool 1, two plug boards 18 can be used for closing. In the present invention, only two structures can realize the assembly of the multi-stage sedimentation tank, which will greatly improve the on-site assembly efficiency.

[0059] In some possible implementation manners, in order to effectively realize the insertion of the slot component 17, so as to realize the closing or opening of the water passing holes 131 as required;

[0060] The slot component 17 has a U-shaped structure, and a slot for mating with the plug board 18 is arranged on the inner side surface of the slot component 17.

[0061] Such as Figure 3 、 Figure 6 As shown, the slot component 17 includes two limiting plates 171 arranged in parallel with a chamber formed therebetween and communicating with the water passing holes 131, and a supporting plate 172 connected to the bottom of the limiting plate 171 and used for supporting the plug board 18. The supporting plate 172 and the limiting plate 171 have the same structure and both have an L-shaped cross-section;

[0062] The limiting plate 171 includes a horizontal plate connected to the plate body and a clamping plate arranged in parallel with the plate body and forming a groove. The openings of the two grooves are arranged on the side close to each other; the two grooves and the chamber cooperate to form a slot.

[0063] When closing the water passing holes 131, the plug board 18 will be installed in the slot to close the water passing holes 131, so that the construction wastewater cannot pass through the water passing holes 131;

[0064] Furthermore, a water-swelling rubber pad is arranged in the slot. The plug board 18 is installed between the two water-swelling rubber pads. When in use, the water-swelling rubber pad swells when encountering water, so that there will be no water leakage at this place;

[0065] In some possible implementation manners, in order to effectively realize the connection between adjacent pool 1 and pool 1, and between adjacent pool 1 and pool 2;

[0066] Such as Figure 2 As shown, the plug-in member 16 includes a U-shaped plate 161 installed on the outer side of the plate body of the first end plate 13 or the second end plate 23 and having a U-shaped structure, and water-swelling rubber bands 162 arranged on the inner and outer sides of the U-shaped plate 161; the cross-sectional length D of the U-shaped plate 161 along the length direction of the first side plate 12 is greater than the cross-sectional length d of the water-swelling rubber band 162 along the length direction of the first side plate 12.

[0067] In some possible embodiments, in order to effectively achieve the connection between adjacent Pool 1 and Pool 1 or Pool 1 and Pool 2 through the cooperation of the plug 15 and the socket 16;

[0068] On the opening side of the Pool 1, there are two groups of plugs 15 with a Z-shaped cross-section respectively connected to two groups of side plates 12 one by one, and the plug 15 is connected to the socket 16 in an adjacent group of Pool 1 or Pool 2.

[0069] In some possible embodiments,

[0070] As Figure 2 shown, the plug 15 includes a connecting plate 151 located in the Pool 1 and forming a U-shaped slot 150 between the connecting plate 151 and the inner side surface of the Pool 1, and a U-shaped mounting plate 152 connected to the connecting plate 151 and having a U-shaped structure. The U-shaped mounting plate 152 is located in the Pool 1 or Pool 2; the U-shaped mounting plate 152 is connected to two adjacent groups of end plates 13, or the end plate 13 and the end plate 23 through bolts; the outer side surface of the U-shaped mounting plate 152 is in the same plane as one end of the side plate 12 away from the end plate 13.

[0071] The connecting plate 151 has a U-shaped structure and cooperates with the inner side of the side plate 12 and the bottom of the bottom plate 11 to form a U-shaped slot 150.

[0072] As Figure 5 shown, the connecting plate 151 includes a plate one connected to the inner side surface of the Pool 1 and a plate two connected to the other end of the plate one; the other end of the plate two is connected to the U-shaped mounting plate 152; the U-shaped mounting plate 152 is provided with a hole one, and a hole two for cooperating with the hole one is provided on the adjacent plate body. One end of the bolt passes through the hole one and the hole two in sequence to realize the connection of two adjacent pools (Pool 1 and Pool 1, or Pool 1 and Pool 2).

[0073] In some possible embodiments, in order to effectively avoid water leakage at the bolt installation location;

[0074] A water-swellable rubber ring is sleeved on the bolt; the water-swellable rubber ring is located between the U-shaped mounting plate 152 of a group of Pool 1 and the U-shaped plate 161 of another adjacent Pool 1 or Pool 2 of this group of Pool 1.

[0075] After assembly, the U-shaped plate 161 will be inserted into the U-shaped slot 150; the water-swellable rubber strip 162 will be located in the gap formed between Pool 1 and Pool 1 or Pool 1 and Pool 2; the water-swellable rubber ring is also located in this gap. The water-swellable rubber ring is pre-tightened by bolts, so that the water-swellable rubber is compressed, and the waterproof effect is better; during use, it absorbs wastewater and swells to stop water at this place.

[0076] The width of the gap is smaller than the widths of the water-swelling rubber band and the water-swelling rubber ring, so as to ensure that the gap is compacted by extrusion.

[0077] In some possible embodiments,

[0078] Drainage holes are provided on the second side plate 22 or the sealing plate 24, and the drainage holes are connected to the municipal pipe network through pipelines, so as to discharge the precipitated wastewater into the municipal pipe network.

[0079] Furthermore, the distance between the drainage holes and the second bottom plate 21 is smaller than the distance between the water passing holes 131 and the first bottom plate 11, and a certain height difference is formed between the axes of the drainage holes and the axes of the water passing holes 131; thus, the construction wastewater entering the present invention can be effectively precipitated, and the precipitation time is longer;

[0080] Even further, there are two groups of drainage holes which are respectively arranged corresponding to the two groups of water passing holes 131 provided on the second end plate 23, and the axes of the drainage holes and the corresponding water passing holes are in the same vertical plane; when the two groups of drainage holes are draining water, a group of drainage holes that do not correspond to the opened water passing holes 131 on the second end plate 23 will be opened; in this way, the precipitation time of the construction wastewater in the second pool is increased, and the precipitation effect is improved;

[0081] An assembling method for a modular multi-stage sedimentation tank specifically includes the following steps:

[0082] Step S1: Detect the construction wastewater and determine that the number of sedimentation stages is n;

[0083] Step S2: According to the number of sedimentation stages, determine the number N of the first pools 1, N=n - 1;

[0084] Step S3: Assemble;

[0085] Step S31: Assemble and connect the first pools 1;

[0086] Step S32: Install the second pool 2 on the opening side of the last group of the first pools 1;

[0087] Step S33: Use the plug board 18 to close the water passing holes 131 of the first group of the first pools 1, close one group of the water passing holes 131 of the remaining plate bodies, and make the remaining group of water passing holes 131 on all the plate bodies be arranged staggeredly to complete the assembly.

[0088] The present invention is not limited to the foregoing specific embodiments. The present invention extends to any new feature or any new combination disclosed in this specification, as well as any new combination of the steps of any new method or process disclosed.
