Description

Technical Field

[0001] This application relates to the technical field of water treatment, and particularly to an inclined plate assembly for a sedimentation tank and an inclined plate sedimentation tank. Background Art

[0002] An inclined plate sedimentation tank is an efficient water treatment device, mainly used to remove suspended substances and particulate matters in water. The inclined plate sedimentation tank occupies a relatively small area, and the inclined plate assembly is designed with multiple parallel inclined plates, constructing channels between each pair of parallel inclined plates. Using the principle of laminar flow, the water to be treated flows between the plates, and the water flow presents a laminar state, which is extremely beneficial for sedimentation, making the inclined plate sedimentation tank more efficient than ordinary sedimentation tanks.

[0003] The inclined plate sedimentation tank includes an inclined plate assembly composed of multiple inclined plates. Currently, most water treatment plants use inclined plate assemblies made of acrylonitrile-butadiene-styrene copolymer (ABS) materials, and most of them are of fixed structures. Multiple parallel inclined plates are fixed together, making it difficult to disassemble a single inclined plate, and the inclined plate assembly with a fixed structure size is only used for a specific application scenario.

[0004] Due to the softness of the ABS material, it is prone to deformation under conditions such as water pressure or sunlight, and its service life is short, requiring regular replacement, resulting in the inclined plate assembly being unable to be reused for a long time; at the same time, due to the fixed structure of the inclined plate assembly, it is not easy to operate and maintain. Summary of the Utility Model

[0005] In view of the above problems in the prior art, this application provides an inclined plate assembly for a sedimentation tank and an inclined plate sedimentation tank to solve the problems that the inclined plate assembly in the related art cannot be reused for a long time and is not easy to operate and maintain.

[0006] To achieve the above object, this application provides the following technical solutions:

[0008] The positioning plates include a plurality of spaced-apart notches, and the remaining parts of the positioning rods passing through the inclined plates are configured to be placed on a set of aligned notches to achieve the fixation of the inclined plates;

[0009] At least two sets of aligned through holes are provided on the angled plate, and one set of through holes is for one of the positioning rods to pass through; there are at least two positioning plates fixed on each side wall, and each positioning plate corresponds to one set of through holes, so that the positioning rod passing through the corresponding set of through holes can be placed through the notch on the positioning plate;

[0010] In an implementable manner, the angle formed by the notch on the positioning plate and the bottom edge of the positioning plate is an acute angle;

[0011] In an implementable manner, the angled plate is integrally formed;

[0012] In an implementable manner, the positioning plate, the angled plate, the positioning rod and the positioning plate are all made of 304 stainless steel;

[0013] In an implementable manner, the thickness of the first stainless steel plate and the second stainless steel plate of the angled plate is less than or equal to 0.635 mm;

[0014] In an implementable manner, the preset angle of the inclined plate assembly is equal to the inclination angle of the inclined plate, and the preset angle is between 75 degrees and 85 degrees;

[0015] On the other hand, the present application provides an inclined plate sedimentation tank, including a first reaction chamber, a second reaction chamber and a third reaction chamber; wherein, the first reaction chamber is located on the left side of the inclined plate sedimentation tank and includes an inlet pipe and a partition for pre-treating the water to be treated. The water to be treated flows through the inlet pipe to the second reaction chamber. The second reaction chamber is located in the middle of the inclined plate sedimentation tank and includes an outlet trough and the inclined plate assembly described in any one of the above items. The inclined plate assembly is used for precipitating suspended substances and particulate matters in the water to be treated, and the precipitated water flows through the outlet trough to the third reaction chamber.

[0016] For the inclined plate assembly and the inclined plate sedimentation tank for a sedimentation tank provided in the embodiments of the present application, the inclined plate assembly replaces the existing ABS material with stainless steel material. Since the stainless steel material has the characteristics of not being easily deformed and high stability, the service life of the inclined plate assembly is improved and it can be reused for a long time. Moreover, the stainless steel material is smoother, so that the sludge can be cleaned in the inclined plate sedimentation tank; the inclined plate assembly is assembled by placing a plurality of positioning rods passing through the inclined plates at the notch positions of the positioning plates, which is convenient for inserting and removing each inclined plate, and changes the fixed inclined plate assembly in the prior art to a plug-in inclined plate assembly, improving the convenience of operation and maintenance of the inclined plate assembly.

[0039] As mentioned in the background technology, the inclined plate assembly in the prior art has the problem that it cannot be reused for a long time and is not easy to operate and maintain. The inventors have found that the reason for this problem is that in the prior art, the inclined plate assembly used by most water plants is acrylonitrile-butadiene-styrene copolymer (ABS) material. Since ABS material is relatively soft, it is easy to deform under factors such as water pressure or sunlight during long-term use, which ultimately leads to poor sedimentation effect and requires regular replacement of the inclined plate. In addition, most of the prior art uses a fixed structure, and when replacing the inclined plate, the entire inclined plate assembly needs to be replaced, and it is not easy to clean.

[0040] In response to the above technical problems, an embodiment of the present application provides an inclined plate assembly for a sedimentation tank, which is composed of a plurality of parallel inclined plates, positioning rods and positioning plates, and is assembled and fixed by placing a plurality of positioning rods passing through the inclined plates in the notches of the positioning plates, so that each inclined plate can be easily removed from the inclined plate assembly. The plug-in inclined plate assembly realized in the above manner can be assembled more conveniently and quickly, and is easy to operate and maintain. By using stainless steel material, the problem of easy deformation of the inclined plate in the prior art is solved because stainless steel material has the characteristics of not being easy to deform and high stability; and stainless steel material is smoother, and suspended matter and particulate matter are not easy to adhere to the inclined plate, so self-cleaning can be achieved during the sedimentation process, and each inclined plate can also be pulled out of the inclined plate assembly for rinsing in the sedimentation tank.

[0041] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0042] An embodiment of the present application provides an inclined plate assembly 100 for a sedimentation tank. The inclined plate assembly 100 includes a plurality of parallel inclined plates 110, positioning rods 120, and positioning plates 130. Refer to Figures 1-4 . Figure 1 is a schematic three-dimensional structure diagram of the inclined plate assembly 100 provided by an embodiment of the present application. Figure 2 is a schematic structure diagram of the inclined plate and the positioning rod after assembly in the inclined plate assembly provided by an embodiment of the present application. Figure 3 is a schematic structure diagram of the positioning rod 120 in the inclined plate assembly provided by an embodiment of the present application. Figure 4 is a schematic structure diagram of the positioning plate 130 in the inclined plate assembly provided by an embodiment of the present application.

[0043] The inclined plate assembly 100 is used to achieve the precipitation of suspended substances and particulate matters during the water treatment process through the laminar flow principle.

[0044] The inclined plate 110 includes a folding plate 111, and the folding plate 111 is as shown in Figure 5 . The inclined plate 110 includes a plurality of folding plates 111, and the inclined plate is composed of a plurality of folding plates 111 arranged closely. The folding plate 111 is composed of two stainless steel plates 112 at a preset angle, and horizontal aligned through holes 113 are provided on the two stainless steel plates 112 that make up the folding plate 111. Figure 1 In

[0045] the example, 2 through holes 113 are provided on one stainless steel plate 112.

[0046] In some embodiments of the present application, 1 through hole 113 can also be provided on one stainless steel plate 112, such as being provided at the middle position of the stainless steel plate 112, and more than 2 through holes 113 can also be provided, such as being evenly spaced along the height direction. In some embodiments, the diameter of the through hole 113 is larger than the diameter of the positioning rod.

[0047] For the convenience of processing and aesthetics, the multiple through holes 113 provided on one stainless steel plate 112 can be aligned, that is, located on a straight line.

[0048] The shape of the stainless steel plate 112 is strip-shaped, and the length is generally set between 1.0 meter and 2.0 meters. This length is crucial for the precipitation effect of suspended substances and particulate matters. This length range can ensure that the suspended substances and particulate matters have sufficient time and space to precipitate.

[0049] It should be noted that the size of the stainless steel plate 112 can be set according to the actual use situation, such as different water quality conditions, water volume, and the size of the sedimentation tank, etc. In some embodiments, the stainless steel plate 112 can also be set as other sheet-like structures.

[0050] The positioning rod 120 is used for the assembly and fixation of the inclined plate 110. The assembly of the inclined plate 110 can be carried out outside the sedimentation tank. The external view of the inclined plate 110 after being assembled using the positioning rod 120 is as shown in Figure 2 shown. The positioning rod 120 is configured to pass through the through hole 113 on the folding plate 111 that makes up the inclined plate 110, and there is an extra protruding part after it passes through the through hole 113. The protruding part is placed on the positioning plate to fix the inclined plate 110.

[0051] The positioning rod 120 is made of 304 stainless steel.

[0052] The shape of the positioning rod 120 can be cylindrical, or it can be other shapes that can pass through the through hole 113 on the folding plate 111, such as a prism. The length of the positioning rod 120 can be approximately equal to the length of the sedimentation tank in the preset direction, and the preset direction is the extending direction of the inclined plate 110.

[0053] In some embodiments of the present application, the length of the positioning rod 120 minus the length of the inclined plate 110 is at least 2l, where l is the minimum length of the extra part at one end after the positioning rod passes through the preset number of folding plates 111. The preset number can be determined based on the ratio of the length of the sedimentation tank in the preset direction to the length of the folding plate 111 in the preset direction.

[0054] By adopting the method of passing the positioning rod 120 through the through hole 113, the splicing of multiple folding plates 111 is realized. The folding plates 111 are arranged adjacent to each other, and finally a long strip-shaped wavy inclined plate 110 is obtained.

[0055] The positioning plates 130 are installed on two opposite side walls of the sedimentation tank, and the distance between them is approximately equal to the length of the sedimentation tank in the preset direction. The extra protruding part after the positioning rod 120 passes through the through hole 113 is placed on the positioning plate, which is used to fix the inclined plate passed through by the positioning rod 120.

[0056] The length of the positioning plate 130 in the preset direction can be equal to the length of the sedimentation tank in the extending direction of the positioning plate 130, so that the inclined plate 110 covers the entire sedimentation tank, increasing the sedimentation area and improving the sedimentation speed of the sludge.

[0057] The positioning plate 130 is made of 304 stainless steel.

[0058] In some embodiments of the present application, the positioning plate 130 is used to fix the position of the inclined plate 110. As shown in Figure 4 shown, the positioning plate 130 includes a plurality of spaced-apart notches 131. The protruding part after the positioning rod 120 passes through the inclined plate 110 is placed on a set of aligned notches 131 on both sides of the inclined plate assembly 100 to realize the fixation of the inclined plate 110. The extra part after the positioning rod 120 passes through the through hole 113 is placed on the corresponding notch 131 to realize the plug-in installation of an inclined plate 110.

[0059] The number of notches 131 on a positioning plate 130 can be greater than or equal to the number of inclined plates 110 in the inclined plate assembly 100, preferably equal to it.

[0060] The notch can be in the shape of a round hole, and the diameter of the notch 131 is greater than or equal to the diameter of the positioning rod 120.

[0061] The angle formed by the notch and the bottom edge of the positioning plate 130 is an acute angle, such as 45°, 60°, etc., to facilitate the insertion and removal of the inclined plate 110.

[0062] In actual use, the positioning plate 130 is fixed on two opposite side walls of the sedimentation tank. When the number of through holes on the stainless steel plate 112 is 2, there are at least 2 positioning plates 130 on each side wall, and the total number of positioning plates 130 in the sedimentation tank is at least 4.

[0063] See Figure 4 , the outer shape structure of the positioning plate 130 can be set to any shape with a fixed groove. Its length can be approximately equal to the length of the sedimentation tank in the preset direction, and the preset direction is the extending direction of the positioning plate 130.

[0064] In some embodiments of the present application, the folding angle plate is composed of two 304 stainless steel plates at a preset angle, and the folding angle plate 111 is integrally formed. At least 2 groups of aligned through holes are provided on the two stainless steel plates 112 of the folding angle plate 111, and one positioning rod 120 passes through one group of through holes. Each positioning plate notch corresponds to one group of through holes to place the positioning rod passing through the corresponding group of through holes through the notch on the positioning plate 130. The included angle between the first stainless steel plate and the second stainless steel plate of the folding angle plate 111 is 80°, and the thickness is less than or equal to 0.635 mm.

[0065] It should be noted that in some instances, the preset number, preset included angle, and preset thickness of the folding angle plate 111 can be the above settings, but are not limited to the above settings and can be adjusted according to the actual size of the sedimentation tank and the water treatment requirements.

[0066] In some embodiments of the present application, the preset number of the folding angle plate 111 can also be specified, and it is achieved by adjusting the preset included angle of the folding angle plate 111. The preset angle can be based on the ratio of the length of the sedimentation tank in the preset direction to the preset number of the folding angle plate 111, and finally calculate the required preset angle of the folding angle plate.

[0067] In some embodiments of the present application, the spacing distance of the notches of the positioning plate 130 determines the spacing of the inclined plates 110, and the number of the notches corresponds to the number of the inclined plates 110 in the inclined plate assembly 100. The size of the positioning plate 130 and the number of the notches can be determined according to the usage situation. The length of the positioning plate 130 is generally the length of the sedimentation tank along the extending direction of the positioning plate 130, aiming to cover the entire sedimentation tank with the inclined plates 110; the number of the notches is the number of the inclined plates 110.

[0068] In some embodiments of the present application, on one side of the inclined plate assembly, the notches of the upper first positioning plate 130 and the lower second positioning plate are arranged staggeredly, so as to realize that the preset inclination angle of the inclined plate 110 is between 75° and 85°. The preset inclination angle of the inclined plate assembly 100 is equal to the inclination angle of the inclined plate 110, and both are between 75° and 85°.

[0069] It should be noted that in some instances, parameters such as the inclination angle of the inclined plate 110, the spacing of the notches 131, and the size of the folding plate 111 need to consider specific treatment requirements, water quality conditions, treatment scale and other factors to ensure the rationality and effectiveness of the design.

[0070] In some embodiments of the present application, since the inclined plate assembly 100 is used for water treatment, the materials used are all 304 stainless steel materials, which are food-grade. However, in some application environments, if there are no specific requirements for the materials, other stainless steel materials can be used.

[0071] The embodiments of the present application further provide an inclined plate sedimentation tank, which can be an efficient sedimentation tank in a water treatment or sewage treatment system, and is used to remove suspended substances and particulate matters in water.

[0072] See Figure 6 As shown, the inclined plate sedimentation tank includes a first reaction chamber 200, a second reaction chamber 300 and a third reaction chamber 400. The first reaction chamber 200 includes a water inlet pipe 210 and a partition plate 220; the second reaction chamber 300 includes an inclined plate assembly 100 and an outlet trough 310.

[0073] The first reaction chamber 200 is located on the left side of the sedimentation tank. See Figure 6 As shown. It includes a water inlet pipe 210 and a partition plate 220. The water inlet pipe 210 is used to transport the water source to be treated, and the partition plate 220 pre-treats the water source to be treated.

[0074] The water inlet pipe 210 is composed of multiple pipes, including a water inlet 211 and a water outlet 212. The water inlet 211 is located outside the sedimentation tank. See Figure 7 As shown. The water to be treated enters the first reaction chamber 200 from the water inlet 211, and after being pre-treated by the partition plate 220, it enters the second reaction chamber through the water outlet 212.

[0075] A plurality of partition plates 220 are horizontally disposed in the first reaction chamber 200, and the partition plates are disposed in the cross-section of the water inlet pipe 210. There are regularly arranged through holes on the partition plates. When water flows through the partition plates 220, due to the mesh number at the position of the partition plates 220 where the water inlet pipe 210 is located, the flow rate of the water source to be treated is controlled, so that the water source to be treated flowing out through the water outlet is uniform and slow.

[0076] In some embodiments, the water inlet pipe 210 is composed of a plurality of pipes, aiming to pass through the partition plates 220 multiple times in a limited space. First, the water to be treated enters above the first reaction chamber 200 through the water inlet 211, then the pipes from top to bottom pass through the partition plates, and then at the bottom of the first reaction chamber 200, the pipes from bottom to top pass through the partition plates again. After multiple repetitions, the water source to be treated enters the second reaction chamber 300 through the water outlet 212.

[0077] It should be noted that the position of the water inlet 211 can be set according to the actual situation, its horizontal height can be set according to the operation situation, and it can be disposed above or below the first reaction chamber 200; Figure 6 The number and mesh number of the middle partition plates only show one embodiment and can be set according to the actual operation situation.

[0078] The second reaction chamber 300 is located in the middle of the sedimentation tank, mainly for sedimentation of suspended substances and particulate matters in the water source to be treated. It includes an inclined plate assembly 100 and a water outlet trough 310.

[0079] The water outlet 212 of the water inlet pipe 210 is communicated with the lower part of the second reaction chamber 300, transporting the water source pretreated in the first reaction chamber 200 to the lower part of the second reaction chamber 300. The water source to be treated enters the inclined plate assembly 100 through the lower part of the inclined plate assembly 100. Since there is a very shallow sedimentation tank equivalent between every two parallel inclined plates 110 in the inclined plate assembly 100, the water to be treated is separated from the settled suspended substances and particulate matters in the shallow sedimentation layer. The separated water moves upward and finally enters the third reaction chamber 400 through the water outlet trough 310 above the sedimentation tank; the separated suspended substances and particulate matters move downward and finally settle at the bottom of the sedimentation tank. Finally, the sedimentation of suspended substances and particulate matters is realized.

[0080] Finally, the water sedimented in the second reaction chamber 300 enters the third reaction chamber 400 through the water outlet trough 310 for the next step of treatment.

[0081] In some embodiments, the second reaction chamber 300 may also include a sludge discharge pipe. The sludge discharge pipe is located below the inclined plate assembly, and there is a sludge discharge pipe corresponding to the lower part of each corner of the folding plate, for collecting the settled suspended substances and particulate matters. The sludge discharge pipe can also quickly collect the settled suspended substances and particulate matters and is easy to clean.
