The lower part of the tank body is symmetrically provided with a plurality of supporting legs 11, and the stability of the whole structure of the treatment tank is ensured.
The upper filter module comprises an upper filter top plate 12 and an upper filter bottom plate 13, a plurality of upper filter inlets 14 are formed in the upper filter top plate, upper filter outlets are formed in the upper filter bottom plate in one-to-one correspondence with the upper filter inlets, the lower filter module comprises a lower filter top plate 15 and a lower filter bottom plate 16, a plurality of lower filter inlets 17 are formed in the lower filter top plate, and lower filter outlets are formed in the lower filter bottom plate in one-to-one correspondence with the lower filter inlets; the upper filter outlet and the lower filter outlet are both provided with stop meshes, and the stop meshes are provided with meshes, so that water flow can not be blocked.
Liquid pipes 18 are provided between the upper filter inlet (of the upper filter top plate) and the upper filter outlet (of the upper filter bottom plate) corresponding thereto, and between the lower filter inlet (of the lower filter top plate) and the lower filter outlet (of the lower filter bottom plate) corresponding thereto; the liquid passing pipe comprises a main pipe body 19 and at least one arc-shaped pipe body 20 on the main pipe body, wherein a transition bend 21 is formed at the joint of the two ends of the arc-shaped pipe body and the main pipe body, a filter piece 22 is arranged in the transition bend, and meanwhile, a flexible deformation zone 23 and a limit stop structure 24 corresponding to the flexible deformation zone are arranged at the transition bend. The limit stop structure can be a protruding structure formed by stamping from outside to inside. The cross-sectional area of the transition bend is smaller than that of the main pipe body (and the arc-shaped pipe body), and the filter element is kept in the transition bend in a normal state so as to fully play the filtering function.
The diameter of the liquid passing pipe gradually increases from the liquid inlet direction to the liquid outlet direction, and the arc-shaped pipe body part of each liquid passing pipe in the upper filter module is communicated with the arc-shaped pipe body parts of at least 1 liquid passing pipe except the liquid passing pipe in the upper filter module through a bypass pipe 25, and the arc-shaped pipe body part of each liquid passing pipe in the lower filter module is communicated with the arc-shaped pipe body parts of at least 1 liquid passing pipe except the liquid passing pipe in the lower filter module through a bypass pipe.
Under normal state, the limit stop structure keeps the filter element on one side of the liquid inlet direction of the flexible deformation area, or the limit stop structure is used for propping against the filter element, so that the filter element is clung to the flexible deformation area, when the filter element is blocked, the flexible deformation area is allowed to expand outwards, so that the filter element which is blocked at present passes over the limit stop structure and moves towards one large-diameter end (lower side) of the liquid passing pipe, and the filter element below is propped against (namely, the filter element below is used for blocking the filter element falling from the upper side, in the process, the filter element can deflect in the direction, and the unblocked mesh part still allows water to pass through, namely, the filter element which is blocked still can play a certain filtering role.
Even if the (upper) filter element is completely blocked, the sewage and waste water can flow at least through the gap between the filter element and the liquid passing pipe due to the reducing structure design of the liquid passing pipe. After the lower filter piece is blocked, the flexible deformation area corresponding to the lower filter piece is deformed, the lower filter piece and the previous falling (upper) filter piece are all crossed with the current limit stop structure so as to eliminate the blocking, and the like, until all filter pieces are blocked, all filter pieces are crossed with the last (i.e. the lowest) limit stop structure, and the limit is formed by the stop net piece at the corresponding liquid outlet, so that the filter pieces are prevented from falling off from the filter module. Compared with a conventional filtering device, the cleaning and maintenance period of the filtering module in the sewage and wastewater treatment equipment is obviously prolonged, and the use and maintenance cost is reduced.
In an alternative embodiment, the flexible deformation zone includes deformable structures 26 on the inner wall of the transition curve or in lieu of the transition curve localized structures. The deformable structure is sealed with the transition bend. As an example, as shown in fig. 7, the deformable structure adopts a plate-like structure capable of being deformed. Typically, the plate-like deformable structure may be made of spring steel. Specifically, the deformable structure with deformation performance can be arranged on the inner wall of the transition bend or the transition bend, and the hollow hole is welded. The filter element is clamped at the deformable structure. As shown in fig. 8, in order to further facilitate the deformation of the deformable structure in the radial direction of the liquid passing pipe, the deformable structure is preferably designed as a corrugated plate with deformation properties.
The filtering piece adopts a spherical structure preferably, and can fully exert the filtering performance by matching with the special structural design of the liquid passing pipe. By way of example, the filter element adopts a spherical structure formed by braiding and winding stainless steel wires, and can be filled with filter filler at the gap in the spherical structure, and when the filter element adopts the spherical structure design, the contact area is very small no matter the filter element is propped against the filter element or the filter element is propped against the stop net sheet, and the water flow can not be influenced, so that the spherical filter element can also play a part of filtering effect after crossing the limit stop structure, but not completely fail. In particular, after the filter element moves in position, the angle of the filter element changes (the loaded surface changes), and the unblocked mesh allows water to pass through, so that the filtering performance is recovered, and the service life of the filter element is prolonged.
It should be noted that the mesh diameter of the filter element in the upper filter module is smaller than the mesh diameter of the filter element in the lower filter module, and the mesh diameter of the stop net sheet is larger than the mesh diameter of the filter element in the lower filter module, so that the stop net sheet does not influence the water flow. The filter elements in the upper filter module and the lower filter module form a two-stage filter system, the upper filter module close to the liquid inlet side performs primary coarse screen filtration, and the lower filter module close to the liquid outlet side realizes secondary fine filtration, so that the sewage filtering treatment effect is very remarkable. The designed bypass pipe can effectively play a role of connecting through the liquid pipe, and because the blockage of the filtering pieces in each liquid passing pipe is not generated at the same time, the bypass pipe can effectively and uniformly disperse water flow, ensure that the structure of the filtering module is stable and the filtering module is kept at the optimal filtering effect, and even if the blockage degree in the liquid passing pipe is different, the water pressure in the liquid passing pipe can be enabled to approach to balance under the communication effect of the bypass pipe.
In a further improved scheme, the diameter of the bypass pipe is 1/2-1/4 of the diameter of the arc-shaped pipe body of the liquid passing pipe, and the joint of the bypass pipe and the arc-shaped pipe body adopts a smooth transition structure. Under the operating mode of high-flow-rate sewage and wastewater treatment operation, by adopting the structural design, the bypass pipe can be approximately venturi effect, when water flows through the bypass pipe, the speed of the water flow can be increased due to the limiting effect of the bypass pipe, the flow can be reduced, a certain flow limiting effect is realized, meanwhile, along with the increase of the water flow speed and the increase of the water pressure, the formed pressure pulse is favorable for improving cavitation intensity, and the sewage and wastewater purification treatment effect is better under the condition that a medicine adding pipe is introduced into a treatment tank. It should be noted that the above structural design is generally used for the high flow rate working condition of sewage and wastewater, and under the conventional working condition, the bypass pipe mainly plays a role in communication, and the structural and pipe diameter designs are unlimited.
The inner wall of the treatment tank is provided with an upper baffle ring 27 and a lower baffle ring 28, the upper surface of the upper baffle ring is attached to the lower end surface of the upper filter bottom plate, and the lower surface of the lower baffle ring is attached to the upper end surface of the lower filter top plate. For example, the upper filter top plate and the lower filter bottom plate are tensioned and fixed by a pull rod 29, so that the upper surface of the upper baffle ring is tightly attached to the lower end surface of the upper filter bottom plate, and the lower surface of the lower baffle ring is tightly attached to the upper end surface of the lower filter top plate. The upper filtering top plate and the lower filtering bottom plate are in sliding fit with the inner wall of the treatment tank, the fit between the filtering module and the treatment tank is very stable when the filtering module is assembled and disassembled, the tightness between the upper filtering top plate and the lower filtering bottom plate and the treatment tank is not required to be ensured, and only the sealing is formed between the upper filtering bottom plate and the treatment tank and between the lower filtering top plate and the treatment tank. In order to further improve the sealing performance, sealing gaskets can be arranged on the upper surface of the upper baffle ring and the lower surface of the lower baffle ring, so that the inside of the treatment tank is divided into a relatively independent water storage cavity, a middle water mixing cavity and a drainage cavity by the filter module, and sewage and wastewater can only flow through the liquid passing pipe between the cavities.
The top end cover is detachably arranged at the top of the tank body, and the bottom end cover is detachably arranged at the bottom of the tank body, so that equipment assembly and cleaning and maintenance of the internal filter module are facilitated. In addition, the stop meshes at the upper filtering outlet and the lower filtering outlet are in a detachable installation mode, and the filtering piece in the filtering module (liquid filtering pipe) is easy to take out and is very convenient to clean, maintain or replace.
The utility model is provided with the upper filtering module and the lower filtering module in the treatment tank, and the inside of the treatment tank is divided into the water storage cavity, the middle muddy water cavity and the drainage cavity which can be independently added with medicaments, thereby laying a good structural foundation for reasonably arranging the water treatment process. The dirty waste water only passes through from the liquid pipe that crosses in the filtration module, fully filters by the filter element in the liquid pipe, and when filter element blocks up, allows the transition bend part deformation of liquid pipe to cross, removes the jam, has prolonged the life of filtration module, and water treatment efficiency and effect homoenergetic can obtain reliable guarantee.
The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the present utility model, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
