Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment accessories, specifically relating to a template for integrally cast filter plates. Background Technology

[0002] In water treatment processes, filtration is an important measure to ensure water quality, while backwashing is the most critical step to restore the cleanliness of the filter media and enable the filter to operate continuously. The water distribution and aeration system is the core component that accomplishes this crucial step.

[0003] In conventional water treatment processes, raw water first undergoes a coagulation-sedimentation process to remove most particulate matter (or direct filtration if water quality is good) before entering the filter tank to prevent rapid clogging of the filter bed. During water filtration, suspended solids and colloidal matter mostly remain on the surface or within the filter bed. Therefore, backwashing is necessary after a period of operation to regenerate the filter bed and ensure the normal operation of the filter tank. In the air-water backwashing process, the key to uniform air and water distribution lies in the flatness of the filter head, which essentially requires the air inlet holes on the filter rod to be on the same horizontal plane. In the past, the filter plates in backwashing processes were mostly small concrete filter plates. Due to the large area of ​​the filter tank, the filter plates in the filter tank were composed of many small unit filter plates spliced ​​together.

[0004] The current integrated casting process for filter plates involves first laying small template pieces in the filter tank, then installing embedded seats in the pre-drilled holes in the template pieces, and finally pouring concrete to form a single filter plate. This solves the sealant problem that existed when splicing small filter plates previously. However, when using this method, the connection structure between the template pieces is not ideal, and gaps may exist between them, causing the caster material to leak through these gaps during casting. Utility Model Content

[0005] This utility model provides a template for integral casting of filter plates, aiming to solve the problem of unreasonable connection structure between template bodies in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A template for integrally cast filter plates includes a template body, wherein the template body is provided with mounting holes;

[0008] Two adjacent template bodies are connected by a connecting component, which includes a connector. The connector has two connecting slots, which are located on both sides of the connector. A portion of each of the two template bodies located on both sides of the connector is located within the connecting slot.

[0009] The connecting assembly further includes a locking device for locking the position of the template body relative to the connector, the locking device being inserted into the connector and the template body.

[0010] A further improved solution: The connector includes an upper plate and a lower plate, with the connecting groove formed between the upper plate and the lower plate, and an intermediate plate disposed between the upper plate and the lower plate, and both the upper plate and the lower plate are integrally formed with the intermediate plate.

[0011] Based on the above technical solution, the upper plate, lower plate, and middle plate adopt an integrated structural design, making the entire connector a continuous and complete whole. In terms of mechanical performance, the integrated structure can better distribute stress, avoiding stress concentration problems caused by the connection of multiple components. When subjected to external forces, traditional connectors composed of multiple independent components are prone to stress concentration at the joints, leading to loosening or damage; while the integrated structure connector can evenly distribute stress throughout the entire structure, greatly improving its resistance to external damage and enhancing structural stability.

[0012] A further improved solution: The template body is provided with a notch to accommodate the lower plate, and the lower surface of the lower plate is flush with the lower surface of the template body.

[0013] Based on the above technical solution: a notch is provided on the template body to accommodate the lower plate. This design allows the lower plate to be precisely embedded into the template body, much like specific shaped pieces in a jigsaw puzzle fitting into corresponding grooves. This precise fitting method greatly increases the contact area between the connector and the template body, thereby improving the strength and stability of the connection. In actual installation and use, mechanical testing has shown that the connection parts using this fitting design can withstand greater external forces and are less prone to loosening or separation.

[0014] A further improved solution: The locking device includes an insert plate, an upper insert hole on the upper plate, a lower insert hole on the lower plate, and a middle insert hole on the template body. The insert plate is inserted into the upper insert hole, the middle insert hole, and then into the lower insert hole in sequence.

[0015] Based on the above technical solution, the insert plate is sequentially inserted into the upper, middle, and lower insertion holes, forming a multi-point locking connection. This design allows the connector and the template body to be fixed at multiple positions, greatly enhancing the stability of the connection. When subjected to external forces, such as lateral pressure from concrete or vibration, the multi-point locking structure can better disperse the external forces, preventing loosening or separation of the connection.

[0016] A further improved solution: There are two insert plates, and the upper insertion hole and the lower insertion hole correspond one-to-one with the insert plates. The locking device also includes a connecting plate that connects the two insert plates.

[0017] Based on the above technical solution: two insert plates are set up, each corresponding to an upper and lower insertion hole, forming a double locking mechanism. Each insert plate is independently inserted into its corresponding upper and lower insertion holes, which is equivalent to setting up two lines of defense at the connection point. When subjected to external impact, such as the vibration force during concrete pouring or the water flow impact force during filter operation, even if one insert plate is loosened to a certain extent, the other insert plate can still maintain the connection state, effectively preventing the connector from separating from the template body.

[0018] A further improved solution: the insert plate and the connecting plate are an integral structure, and the connecting plate is provided with a handle for easy operation of the locking device.

[0019] Based on the above technical solution: the insert plate and connecting plate adopt an integrated structure, eliminating the connection gaps and weak points that may exist in traditional assembled structures. When subjected to external forces, the force can be evenly distributed throughout the entire integrated structure, avoiding structural damage caused by localized stress concentration. The integrated structure makes all parts of the locking device an organic whole, with better overall rigidity and resistance to deformation. During long-term use, even under frequent external forces and environmental factors such as temperature changes and chemical corrosion, deformation is not easily observed.

[0020] A further improved solution: the handle is located on the side of the connecting plate away from the insert plate, and the handle is welded to the connecting plate.

[0021] Based on the above technical solution: because the handle is far from the insert plate, operators maintain a safe distance between their hands and the sharp edges of the insert plate when holding the handle, greatly reducing the risk of hand cuts or punctures. In some filter bed construction projects with high safety requirements, this design can effectively protect the personal safety of operators and reduce the occurrence of safety accidents.

[0022] A further improved solution: The template body is provided with protrusions, which are evenly distributed on the template body, and the mounting holes are provided on the protrusions.

[0023] Based on the above technical solution, the uniform distribution of protrusions enhances the rigidity of the template in all directions. During the use of the template, whether subjected to the impact of horizontal water flow or the gravity of concrete in the vertical direction, the uniformly distributed protrusions provide support and stability, allowing the template to maintain its original shape and size, thus ensuring the precision and quality of the filter structure. Actual structural mechanics tests have shown that the template with uniform protrusions deforms significantly less than ordinary templates under the same external force.

[0024] A further improved solution: the mounting holes are evenly distributed on the protrusion, and the protrusion and the template are an integral structure.

[0025] Based on the above technical solution: the protrusions of the integrated structure are tightly integrated with the template, which is equivalent to adding multiple reinforcing ribs to the template. The presence of the protrusions increases the moment of inertia of the template section, improving the template's ability to resist bending deformation. At the same time, the evenly distributed mounting holes work together with the protrusions to form a stable force-bearing system when the template is subjected to external forces, enhancing the overall rigidity and strength of the template.

[0026] A further improved solution: The protrusion is further provided with an auxiliary ring to increase the depth of the mounting hole. The auxiliary ring corresponds one-to-one with the mounting hole. The auxiliary ring and the protrusion are an integral structure. The auxiliary ring communicates with the mounting hole and is coaxially arranged with the mounting hole.

[0027] Based on the above technical solution: because the auxiliary ring and the protrusion are an integral structure and coaxially connected with the mounting hole, this design makes the template form a more robust whole at the connection point. When subjected to external forces, the force can be transmitted more evenly to the entire template structure through the auxiliary ring and the mounting hole, reducing local stress concentration, thereby improving the overall rigidity of the template system and ensuring the dimensional accuracy and stability of the filter structure.

[0028] The beneficial effects of this utility model are as follows:

[0029] This invention uses a connector's connecting slot to tightly fit the template body, and further secured by a locking device, physically eliminating the possibility of gaps. During long-term operation of the filter, the impact of water flow and changes in water pressure can affect the filter plate structure. This template's connection structure can withstand these external forces, maintaining a tight connection between the template bodies and preventing loosening and leakage.

[0030] The monolithically cast filter plates have no seams, forming a continuous and complete structure. Compared with traditional spliced ​​filter plates, their structural strength is greatly improved. Under the same water pressure and external forces, monolithically cast filter plates can better distribute stress, avoid damage caused by local stress concentration, and ensure the safe and stable operation of the filter tank.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by users of the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] refer to Figures 1 to 3 A template for integrally cast filter plates includes a template body 1, wherein the template body 1 is provided with mounting holes 2;

[0039] Two adjacent template bodies 1 are connected by a connecting component 3. The connecting component 3 includes a connector, and the connector is provided with a connecting groove 4. There are two connecting grooves 4, which are located on both sides of the connector. A portion of each of the two template bodies 1 located on both sides of the connector is located in the connecting groove 4.

[0040] The connecting assembly 3 further includes a locking device 5 for locking the position of the template body 1 relative to the connector, the locking device 5 being inserted into the connector and the template body 1.

[0041] The connector includes an upper plate 6 and a lower plate 7, with a connecting groove 4 formed between the upper plate 6 and the lower plate 7. An intermediate plate 8 is provided between the upper plate 6 and the lower plate 7, and the upper plate 6 and the lower plate 7 are integrally formed with the intermediate plate 8. The template body 1 has a notch 9 for accommodating the lower plate 7, and the lower surface of the lower plate 7 is flush with the lower surface of the template body 1. The locking device 5 includes an insert plate 10. The upper plate 6 has an upper insertion hole 11, the lower plate 7 has a lower insertion hole, and the template body 1 has a middle insertion hole 12. The insert plate 10 is inserted into the upper insertion hole 11, the middle insertion hole 12, and then into the lower insertion hole. There are two insert plates 10, with the upper insertion hole 11 and the lower insertion hole corresponding one-to-one with each insert plate 10. The locking device 5 also includes a connecting plate connecting the two insert plates 10. The insert plate 10 and the connecting plate are integrally formed. The connecting plate is provided with a handle 14 for easy operation of the locking device 5. The handle 14 is located on the side of the connecting plate away from the insert plate 10 and is welded to the connecting plate. Positioning the handle 14 on the side of the connecting plate away from the insert plate 10 allows the operator's arm to be in a naturally extended position when holding the handle 14 to operate the locking device 5, reducing fatigue caused by arm twisting or excessive force. For example, when installing or removing the locking device 5 of the filter template, the operator can easily hold the handle 14 and apply force in a more comfortable posture to complete the insertion or removal of the insert plate 10, greatly improving the convenience and comfort of operation, especially suitable for work scenarios requiring prolonged operation of the locking device 5.

[0042] Specifically: The template body 1 is provided with protrusions 15, which are evenly distributed on the template body 1, and mounting holes 2 are provided on the protrusions 15. The mounting holes 2 are evenly distributed on the protrusions 15, and the protrusions 15 and the template are an integral structure. An auxiliary ring is also provided on the protrusions 15 to increase the depth of the mounting holes 2. The auxiliary ring corresponds one-to-one with the mounting holes 2, and the auxiliary ring is an integral structure with the protrusions 15. The auxiliary ring communicates with the mounting holes 2 and is coaxially arranged with the mounting holes 2. The auxiliary ring can be designed with different sizes and depths according to actual needs to accommodate bolts and other connecting parts of different specifications. This makes the template more adaptable and can be matched with various types of support structures and connection methods in different filter engineering projects. For example, in some special filter engineering projects with high requirements for connection strength, larger bolts can be used with auxiliary rings of appropriate depth to ensure the installation of the template firmly. This standardized design of the auxiliary ring and mounting holes 2 makes the template highly versatile. The templates produced in different batches maintain consistency in the size and position of mounting holes 2 and auxiliary rings, facilitating template reuse and interchangeability. In the construction of multiple filter projects, templates of the same specifications can be procured and used uniformly, reducing the cost and time of customizing templates for specific projects and improving template utilization efficiency and economic benefits.

[0043] The working principle of this embodiment:

[0044] Place the connector between two adjacent template bodies 1, so that a portion of the template body 1 is embedded in the connector's connecting groove 4. Then, insert the locking device 5 onto the connector and the template body 1 to lock the position of the template body 1 relative to the connector, completing the laying of the template body 1. Install the embedded seat in the reserved hole of the template body 1 to prepare for subsequent concrete pouring. Pour concrete into the filter tank, filling the space between the template bodies 1 and the space between the template body 1 and the embedded seat, forming a unified filter plate.
