Technical Field
[0001] The utility model relates to a simple filtering device for circulating return water. Background Art
[0002] In the production process of printing plate materials, the aluminum plate base needs to be treated with chemical surface treatment and then washed. The washing process is a common and important process, which usually consists of a circulating water loop consisting of a storage tank, a pump, a spray nozzle and a pipeline (refer to Figure 7 ), industrial water is generally used here, which contains mud and sand impurities, and impurities are also produced in the production process. These impurities are likely to cause product defects, affecting product quality and yield rate. Filtering this circulating water will have better benefits. Due to different understandings of the process, some manufacturers design and install independent filters in the circulation loop, and the filters are installed on the supply end of the pump outlet, but this method generally requires the use of two sets of filters, "one for use and one for backup", for switching use, which will significantly increase costs and require more floor space. Therefore, designing a simple filtering device that can save costs and achieve the purpose of filtering is the research direction of this utility model. Utility Model Content

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.
[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0028] This embodiment provides a simple circulating water filtering device, the structure of which is as follows Figure 1 and Figure 2As shown, it includes a tank cover plate 1, a top of which is provided with a return pipe 2 for connecting to a process tank, an outer wall of the return pipe 2 is provided with a connecting flange 3, and a plurality of locking bolts (not shown in the figure) are provided on the connecting flange 3 for fixing the return pipe 2.
[0029] like Figure 1 and Figure 2 As shown, an adapter component 4 is arranged at the bottom of the tank cover 1; the adapter component 4 includes a fixing member 40, a card slot 42 is provided in the fixing member 40, and the edge of the card slot 42 extends inward to form a support portion 43, and the support portion 43 is used to fix the support card plate 50 in the connecting component 5 in the card slot 42, and the first end of the support card plate 50 is provided with a sleeve 51 communicated with the return pipe 2, so that the return water flows from the sleeve 51 to the filter bag sleeved on the end of the sleeve 51, and the second end of the support card plate 50 is provided with a pull-out handle 54, and the pull-out handle 54 is provided with a threading hole 55 for connecting the closing rope on the filter bag, so that the filter bag is fixed to the sleeve 51 through the closing rope, and the first end of the sleeve 51 is formed with an anti-slip flange 56 for fixing the filter bag.
[0030] The through hole 55 is arranged on the pull handle 54 obliquely upward, parallel or obliquely outward (see Figure 8 ). Preferably, the tie hole 55 is arranged obliquely upward on the pull-out handle 54. The advantages of such arrangement are: (1) it can be used to provide a stable support point. By passing the closing rope through the tie hole 55 and tying a knot or using other fixing devices, it can be ensured that the closing rope will not slip when subjected to force; (2) the tie hole 55 opened obliquely upward can make the closing rope form an angle with the vertical or horizontal direction, thereby changing the direction of the force, which is very important in mechanics because it can help disperse the load, reduce the pressure on a certain point, or make the force more effectively transmitted to the target object; (3) the tie hole 55 opened obliquely upward can reduce the wear of the closing rope when subjected to force, because the tie hole 55 opened obliquely upward can make the closing rope maintain a certain curvature when subjected to force, thereby reducing the direct friction area; (4) the tie hole 55 opened obliquely upward can adjust the tension and angle of the closing rope according to actual needs, so that it can adapt to various usage scenarios and conditions.
[0031] In this embodiment, the anti-slip flange 56 (also called flared opening or flange) can: (1) increase the surface area of the end of the sleeve 51, thereby providing a larger contact surface and better support, which helps to fix the filter bag and reduce the movement or fall of the filter bag caused by water flow impact or external force; (2) the design of the anti-slip flange 56 (flared opening or flange) can make it easier to install the filter bag on the sleeve 51, and also facilitate future removal and replacement. At the same time, this design can also be used in conjunction with a clamp or other fixing device to achieve quick and easy installation; (3) the anti-slip flange The design of 56 (flared or flange) provides a flat sealing surface, which helps to achieve a good seal between the filter bag and the sleeve 51, which is crucial to preventing liquid leakage and ensuring filtration efficiency; (3) The anti-slip flange 56 treatment can enhance the mechanical strength of the end of the sleeve 51, making it more able to withstand the stress that may be generated during connection and use, and reduce the filter bag from falling off due to material fatigue or damage; (4) The design of the anti-slip flange 56 can adapt to a variety of connection methods, such as threaded connection, flange connection, clamp connection, etc., which provides flexibility for the configuration and maintenance of the filtration system. However, it should be noted that although the anti-slip flange 56 treatment can significantly improve the stability and reliability of the connection between the filter bag and the sleeve 51, it does not mean that the filter bag will never fall off. Therefore, in actual applications, factors such as the working pressure, temperature, chemical compatibility of the filtration system, and the material and quality of the filter bag and sleeve 51 need to be considered.
[0032] Furthermore, the closing rope of the filter bag passes through the tie-through hole 55 of the pull-out handle 54 and is tied securely, which is the second line of defense to prevent the filter bag from falling off and plays a double insurance role.
[0033] In this embodiment, the filter bag is installed at the first end of the casing 51 (the end of the return pipe 2), rather than at the supply end of the pump outlet. Therefore, the pump head requirement is smaller, the power of the motor matched with the pump can be smaller, the pump set cost is lower, and it is more power-saving and energy-saving in normal use. Moreover, if an independent filter is installed at the supply end of the pump outlet, it is generally necessary to use two sets of filters, "one for use and one for backup", for switching use, which will significantly increase the cost and require a larger floor space. Therefore, the location where the filter bag is installed in this embodiment is obviously more energy-saving and more suitable for promotion and use by enterprises.
[0034] Among them, the filter bag is installed at the first end of the sleeve 51 (the end of the return pipe 2) instead of being installed at the supply end of the pump outlet. This arrangement means that the filter device does not need to overcome the flow and pressure losses of the entire system. Therefore, the required pump head can be relatively low, which can reduce the energy consumption of the pump and reduce the operating cost of the pump. At the same time, due to the low head and flow requirements of the pump, a smaller and lower-cost pump can be selected, which can save costs in the initial investment and also reduce the maintenance and replacement costs of the pump. Furthermore, installing a filter device at the return end can make full use of potential energy and reduce the energy consumption of the pump, because the pump does not need to provide additional pressure to overcome the resistance of the filter device, which can improve the energy efficiency of the entire system and reduce energy consumption. Secondly, since the filter device is installed at the return end, the pipeline design of the system can be simpler, reducing the need for additional pipelines and accessories, thereby reducing material costs and installation costs. Finally, the filter bag installed at the return end can more effectively capture impurities in the return flow and protect the pump and other system components from wear and blockage, thereby improving the reliability and life of the entire system. Therefore, in this case, installing the filter bag at the first end of the casing 51 (the end of the return pipe 2) can greatly save costs and reduce losses.
[0035] Furthermore, the material, size and pore size (precision) of the filter bag can be selected according to the requirements of the product production process.
[0036] like Figure 2 As shown, the second end of the sleeve 51 is sleeved and fixed on the first end of the supporting card plate 50, and a height difference is formed for installing the sealing ring 52, so that one end of the return pipe 2 extends into the fixing member 40 through the through hole 41 and abuts against the second end of the sleeve 51, thereby being sealed by the sealing ring 52, so that the return water can be smoothly discharged into the filter bag through the sleeve 51.
[0037] Embodiment 2, a simple filtering device for circulating return water, is different from Embodiment 1 in that: Figure 3-5 As shown, the structures of the support card plate 50 and the fixing member 40 are different from those in the first embodiment. In this embodiment, a second hidden groove 44 is provided on the card slot 42, and a locking opening 45 is formed at one end of the second hidden groove 44. A third hidden groove 57 is provided on both sides of the support card plate 50. A second connecting rod 510 is fixedly provided in the third hidden groove 57. A clamping rod 58 is rotatably provided on the second connecting rod 510. An abutting end 59 for connecting with the locking opening 45 is fixedly provided at one end of the clamping rod 58, so as to fix the support card plate 50. A second spring 511 for use with the clamping rod 58 is also provided inside the third hidden groove 57. A push-pull structure for use with the clamping rod 58 is symmetrically provided on both sides of the fixing member 40. The push-pull structure includes a push rod 46. A fixing ring 47 is sleeved on the outer wall of the push rod 46. A fourth spring 48 for retracting the push rod 46 is provided on the fixing ring 47.
[0038] In actual use, in order to make the supporting card plate 50 have the ability of self-locking and at the same time enhance the stability of the supporting card plate 50, the present embodiment is provided with a self-locking fixing structure on both sides of the supporting card plate 50. The structure can allow the card rod 58 to enter the third hidden groove 57 with the second spring 511 due to pressure when the supporting card plate 50 enters the card slot 42. When the supporting card plate 50 completely enters the card slot 42, the third spring 6 provided on the card slot 42 abuts against the middle of the arc edge of the supporting card plate 50, and the second hidden groove 44 is flush with the third hidden groove 57, and provides a space for the second spring 511 to release the card rod 58, so that the abutting end 59 at one end of the card rod 58 is inserted into the locking opening 45 , then, release the support card plate 50, the third spring 6 rebounds to make the card rod 58 more stable, and at the same time, fix the support card plate 50; during disassembly, since the push rod 46 extends into the fixing member 40 and can be stretched back and forth by the fourth spring 48, at this time, the support card plate 50 can be pressed backward by the third spring 6, so that the abutting end 59 on the card rod 58 is out of the locking opening 45, and then, the fourth spring 48 is used to press the push rod 46 toward the second hidden groove 44, so that the card rod 58 can be flush with the second hidden groove 44, and then, release the push rod 46, and the third spring 6 pushes the support card plate 50 out of the card slot 42, thereby completing the disassembly and realizing the rapid installation and disassembly of the support card plate 50.
[0039] Embodiment 3, a simple filtering device for circulating return water, is different from Embodiment 1 in that: Figure 6 As shown, the structure of the support portion 43 is different from that of Embodiment 1 or Embodiment 2. In this embodiment, a first hidden groove 430 is provided on the support portion 43, a first connecting rod 431 is rotatably provided inside the first hidden groove 430, a supporting rod 432 is sleeved on the outer wall of the first connecting rod 431, a first spring 433 for connecting with the supporting rod 432 is fixedly provided inside the first hidden groove 430, and a parallel portion 434 for supporting the bottom of the supporting card plate 50 is formed at one end of the supporting rod 432.
[0040] In actual use, since the support card plate 50 and the fixing member 40 are simple structures, there will be some differences from the actual required products during processing, such as some gaps after the two are combined, thereby leaking the smell in the backflow water, or the liquid will also leak under long-term use. Therefore, a structure for supporting and abutting the support card plate 50 is provided on the support portion 43. When the support card plate 50 is inserted into the slot 42 and supported by the support portion 43, the support rod 432 supports the support card plate 50 by the first spring 433, and the force generated by the first spring 433 makes the parallel portion 434 on the support rod 432 fit with the support card plate 50, and the top surface of the support card plate 50 can better fit with the fixing member 40, so that the support card plate 50 has a lifting effect and minimizes the gap between the two, thereby avoiding odor or liquid leakage in the backflow water.
[0041] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
