Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a wastewater sedimentation and impurity separation device. Background Technology

[0002] Wastewater treatment sedimentation processes require a variety of equipment that work together to effectively settle and separate suspended solids, sludge, and other impurities from wastewater. Existing wastewater sedimentation and impurity separation devices mainly include: firstly, using a screen as the first stage of filtration to intercept large particles and suspended solids, preventing them from entering subsequent treatment equipment and causing blockages and damage; then, the wastewater enters an equalization tank, primarily used to regulate the water quality and quantity to maintain stability; next, the wastewater enters a sedimentation tank, the core equipment in the wastewater treatment sedimentation process, mainly used to remove suspended particles, sludge, and other impurities; finally, the sludge separated from the sedimentation tank requires further treatment and disposal. Common sludge treatment equipment includes sludge pumps, sludge thickeners, and sludge dewatering machines, which reduce and stabilize the moisture content of the sludge, facilitating subsequent disposal.

[0003] However, when wastewater is filtered and separated by a screen, existing screens are all integrally molded after production. They mainly consist of a rectangular frame and internally fixed welded horizontal and vertical partitions. The rectangular frame is fixedly connected and cannot be separated. The horizontal and vertical partitions are also welded to the inner wall of the fixed frame. In use, firstly, it is inconvenient to carry and transport; secondly, it is impossible to adjust the spacing between adjacent vertical partitions according to filtration needs; and thirdly, once one or more horizontal or vertical partitions are damaged or deformed, they cannot be disassembled and replaced individually, and the entire screen needs to be replaced, making it quite inconvenient to use.

[0004] Therefore, it is necessary to invent a wastewater sedimentation and impurity separation device. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater sedimentation and impurity separation device, comprising a fixed frame A and a fixed frame B, wherein the fixed frame B is movably connected to the fixed frame A, a limiting component is installed on the upper end of the fixed frame B, and longitudinal partitions are installed inside the fixed frame A and the fixed frame B, with a transverse partition snapped onto the upper part of the longitudinal partition.

[0007] Based on the above features: Fixing frame A and fixing frame B can be pre-assembled into a frame, which forms a rectangular U-shaped structure. Then, longitudinal partitions are installed at intervals inside the frame, and then transverse partitions are snapped onto the upper part of the longitudinal partitions to form a grid. After the longitudinal partitions are installed, limiting components can be used to limit their sides to improve the fixing effect. This not only facilitates quick assembly of the whole, but also makes it easy to carry and transport before assembly.

[0008] Preferably, the fixing frame A has slots symmetrically opened at both ends, and an insertion hole is opened above the slot.

[0009] Based on the above features, it is convenient for the mounting bracket A to be connected and fixed to the mounting bracket B using slots and holes.

[0010] Preferably, the upper end of the fixing frame B is provided with a connecting groove spaced apart on one side, and the fixing frame B is symmetrically installed with plugs on both sides, and the plugs are provided with a through hole in the middle.

[0011] Based on the above features: when assembling the fixing frame A and the fixing frame B, the insert block is inserted into the slot so that the two ends of the fixing frame A are quickly fitted and aligned with the two sides of the fixing frame B.

[0012] Preferably, the through hole and the insertion hole have the same diameter.

[0013] Based on the above features: when the through hole in the middle of the plug is aligned with the plug hole above the slot, screws or locating pins can be inserted into the plug hole and through hole to fix them in place, preventing them from separating on their own.

[0014] Preferably, the limiting component includes a fixed base and a movable groove opened on one side of the fixed base. A limiting plate is movably connected inside the movable groove. A baffle is installed at one end of the limiting plate, and a buffer spring is installed at the end of the baffle away from the limiting plate.

[0015] Based on the above features, the limiting plate can be easily extended and retracted on one side of the fixed seat via the movable groove, which can limit the movement of both sides of the longitudinal partition after installation.

[0016] Preferably, the fixed base has a hollow structure inside, and the baffle and buffer spring are located in the inner cavity of the fixed base.

[0017] Based on the above characteristics: When installing the longitudinal partition, push the limiting plate into the fixed seat, so that the limiting plate compresses and deforms the buffer spring. After the longitudinal partitions are installed one by one, the limiting plate can be released. At this time, the buffer spring will rebound the limiting plate to the upper limit of the connecting groove.

[0018] Preferably, protrusions are symmetrically installed on both sides of the upper end of the longitudinal partition, and positioning slots are spaced apart on the upper surface of the longitudinal partition.

[0019] Based on the above features: when the longitudinal partition is inserted into the frame, the protrusion will also be locked inside the connecting groove. Then, the transverse partition can be inserted into the positioning slot, so that the longitudinal partition and the transverse partition form a cross-shaped structure.

[0020] The beneficial effects of this utility model are:

[0021] 1. Fixture A and Fixture B can be movably assembled into a rectangular frame for easy carrying and transportation. Then, the longitudinal and transverse partitions are installed inside the frame. When installing the longitudinal partition, align the protrusions on both sides of its upper end with the connecting groove, and then insert the longitudinal partition into the frame. The protrusions will also be locked inside the connecting groove. During this process, the spacing between adjacent longitudinal partitions can be adjusted according to the filtration needs. Finally, the transverse partition can be inserted into the positioning slot above the longitudinal partition and fixed to facilitate the formation of the entire screen for filtering sewage. When the entire screen is not in use or when the longitudinal or transverse partitions are damaged, the damaged longitudinal or transverse partitions can also be disassembled and replaced.

[0022] 2. Before installing the longitudinal partition in the inner cavity of the frame, the limiting plate can be pushed into the fixed seat to deform the limiting plate by squeezing the buffer spring. At this time, the connecting groove will also be exposed. When the protrusion is engaged in the inner side of the connecting groove, the limiting plate can be released. At this time, the buffer spring will rebound the limiting plate to the upper limit of the connecting groove, preventing the protrusion from separating from the connecting groove and improving the fixing effect and stability.

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] See attached document Figure 1-4 This utility model provides a wastewater sedimentation and impurity separation device. The first step in wastewater treatment is to use a bar screen as the first filtration device. The bar screen used for wastewater separation in this application is assembled from a fixed frame A1, a fixed frame B2, a limiting component 3, a longitudinal partition 4, and a transverse partition 5. The fixed frame A1 and fixed frame B2 can be pre-assembled into a frame, which, after assembly, forms a rectangular U-shaped structure. There are two sets of fixed frames A1 and B2. Before assembling the fixed frames A1 and B2, the two sets of fixed frames B2 are symmetrically arranged at both ends of the fixed frame A1, and the inserts 22 symmetrically installed on one side of the fixed frame B2 are aligned with the slots 11 at both ends of the fixed frame A1. During the assembly of the fixed frames A1 and B2... Insert the plug 22 into the slot 11 so that the two ends of the fixing bracket A1 are aligned with the two sides of the fixing bracket B2. Since the plug 22 has a through hole 23 in the middle and the slot 11 has a plug hole 12 on the top, the through hole 23 in the middle of the plug 22 will be aligned with the plug hole 12. Finally, use screws or positioning pins (not shown in the figure, existing technology, explained here) to fix it inside the plug hole 12 and the through hole 23. When it is necessary to disassemble, simply remove the screws or positioning pins from the plug hole 12 and the through hole 23, and then pull the fixing bracket B2 away from the fixing bracket A1 to separate the plug 22 from the slot 11. This not only facilitates the quick assembly of the fixing bracket A1 and the fixing bracket B2, but also makes it convenient to carry and transport before assembly.

[0030] The limiting component 3 includes a fixed base 31, a movable groove 32, a limiting plate 33, a baffle 34, and a buffer spring 35. The fixed base 31 is fixedly installed on the upper end of the fixed frame B2. The inner cavity of the fixed base 31 is a hollow structure, and a movable groove 32 is also provided on the lower end of one side of the fixed base 31. The limiting plate 33 can move through the movable groove 32. A baffle 34 is fixedly installed on one side of the limiting plate 33. The diameter of the baffle 34 is larger than that of the movable groove 32. A buffer spring 35 is installed on the end of the baffle 34 away from the limiting plate 33. The baffle 34 and the buffer spring 35 are located in the inner cavity of the fixed base 31 to prevent the limiting plate 33 from separating from the fixed base 31, and at the same time facilitate the extension and retraction adjustment of the limiting plate 33 on one side of the fixed base 31 through the movable groove 32.

[0031] Multiple longitudinal partitions 4 and transverse partitions 5 are provided. When it is necessary to install longitudinal partitions 4 and transverse partitions 5 inside the frame, multiple connecting slots 21 need to be opened in advance on the upper side of one side of the fixed frame B2. The connecting slots 21 are spaced apart, with the distance between adjacent connecting slots 21 set to 5mm. The inner diameter of the connecting slots 21 is set to 5mm, and the thickness of the longitudinal partitions 4 is also set to 5mm. Protrusions 41 are fixedly installed on both sides of the upper end of the longitudinal partitions 4. Before installing the longitudinal partitions 4, the distance between adjacent longitudinal partitions 4 should be adjusted as needed. When the distance between adjacent longitudinal partitions 4 needs to be 5mm, longitudinal partitions 4 can be installed in each connecting slot 21. When the distance between adjacent longitudinal partitions 4 needs to be 10mm, one longitudinal partition 4 can be installed every other connecting slot 21, and so on. This makes it convenient to adjust the distance between adjacent longitudinal partitions 4 according to the filtration requirements. When installing the longitudinal partitions 4, the limiting plate 33 is pushed into the fixed seat 31, so that the limiting plate 33 compresses the buffer spring. The longitudinal partition 4 is deformed to facilitate the leakage of the connecting groove 21. Then, the protrusions 41 on both sides of the upper end of the longitudinal partition 4 are aligned with the connecting groove 21. Next, the longitudinal partition 4 is inserted into the frame, and the protrusions 41 will also be stuck inside the connecting groove 21. After the longitudinal partitions 4 are installed one by one, the limiting plate 33 can be released. At this time, the buffer spring 35 will rebound the limiting plate 33 to the top of the connecting groove 21, which is convenient for limiting the protrusions 41 stuck inside the connecting groove 21 and preventing the protrusions 41 from separating from the connecting groove 21. Since the longitudinal partition 4 has a positioning slot 42 (the spacing and number of positioning slots 42 are not specifically limited and can be set according to the needs), the inner diameter of the positioning slot 42 is adapted to the thickness of the transverse partition 5. Finally, the transverse partition 5 can be inserted into the positioning slot 42, so that the longitudinal partition 4 and the transverse partition 5 form a cross-shaped structure, thereby forming the entire screen for separating sewage. It is convenient to adjust the spacing or replace the longitudinal partition 4 and the transverse partition 5 individually according to the filtration needs.

[0032] It should be noted that the lengths of the fixing frame A1, fixing frame B2, limiting component 3, longitudinal partition 4 and transverse partition 5 are not specifically limited in this application, and the connecting groove 21 above the fixing frame B2 and the positioning slot 42 above the longitudinal partition 4 are also not specifically limited. The number of longitudinal partition 4 and transverse partition 5 is also not specifically limited and can be set according to the needs of use. This application is for reference only.

[0033] The usage process of this utility model is as follows: When assembling the grille, insert the two side blocks 22 of one end of the fixing frame B2 into the slots 11 on both sides of the fixing frame A1, so that the two ends of the fixing frame A1 are quickly aligned with the two sides of the fixing frame B2. At this time, the through hole 23 in the middle of the insert 22 will be aligned with the insertion hole 12 above the slot 11. Then, use screws or positioning pins to insert into the insertion hole 12 and the through hole 23 to fix it, so that the fixing frame A1 and the fixing frame B2 are assembled into a rectangular frame. When disassembly is required, simply remove the screws or positioning pins from the insertion hole 12 and the through hole 23, and then pull the fixing frame B2 away from the fixing frame A1 to separate the insert 22 from the slot 11. When installing the longitudinal partition 4 and the transverse partition 5, first push the limiting plate 33 into the fixed seat 31, so that the limiting plate 33 compresses the buffer spring 35 and deforms. Then, align the protrusions 41 on both sides of the upper end of the longitudinal partition 4 with the connecting groove 21. Next, insert the longitudinal partition 4 into the frame, and the protrusions 41 will also be stuck inside the connecting groove 21. After the longitudinal partitions 4 are installed one by one, the limiting plate 33 can be released. At this time, the buffer spring 35 will rebound the limiting plate 33 to the upper limit of the connecting groove 21. Finally, the transverse partition 5 can be inserted into the positioning slot 42 above the longitudinal partition 4, so that the longitudinal partition 4 and the transverse partition 5 form a cross-shaped structure, thereby forming the entire screen for separating sewage.
