Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water treatment control, in particular to a sedimentation device. BACKGROUND

[0002] The inclined plate (inclined tube) sedimentation tank is a kind of sedimentation tank which uses "shallow layer theory" and adds inclined plate or inclined tube filler in the sedimentation tank to improve sedimentation efficiency. In the actual operation process of water treatment facilities, the inclined plate (inclined tube) sedimentation tank may have the following problems in different process applications:

[0003] (1) The sludge is blocked in the inclined plate or inclined tube and deposited on the top. If appropriate measures are not taken in time, the sludge will be deposited in large quantities on the top of the inclined plate and inclined tube and spread around, and the sludge cannot be normally discharged from the hopper;

[0004] (2) Air bubbles will come out of the water surface of the sedimentation tank and be accompanied by a large amount of floating sludge, and the water quality will be deteriorated due to a large amount of particulate matter carried out of the water;

[0005] (3) The inclined plate and inclined tube are compressed and deformed, causing continuous deterioration of the water quality of the equipment, and in severe cases, the filler layer collapses and even the filler support is crushed, causing the equipment to be shut down, which affects the stability of production.

[0006] The above problems are related to the blockage of the filler layer of the inclined tube or inclined plate. The filler layer of the traditional inclined tube sedimentation tank or inclined plate sedimentation tank is fixed above the filler support and submerged in water. In the operation process of the sedimentation tank, the initial blockage of the filler layer is not easy to find. When the blockage of the filler layer is found to be visible to the naked eye, the blockage is already very serious, causing deformation and collapse of the filler layer, resulting in the filler layer being scrapped, and the sedimentation device having to be shut down for replacement of the filler layer. SUMMARY

[0007] The purpose of the present application is to provide a sedimentation device which can timely find the blockage of the filler layer and determine the direction of the blockage.

Therefore, the features defined as "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0036] like Figure 1 As shown, the present invention provides a sedimentation device, which includes a sedimentation shell 1, a filling rack 3 and a level 5, wherein:

[0037] The precipitation shell 1 is a hollow structure with an open upper end. Specifically, the upper end of the precipitation shell 1 forms a water outlet, and a water inlet (not shown in the figure) is arranged on the side wall of the precipitation shell 1 below the filler frame 3. A plurality of spaced-apart weighing members 2 are connected to the upper end of the precipitation shell 1. The upper end of each weighing member 2 is connected to a cantilever 21 that extends horizontally towards the inside of the precipitation shell 1. Specifically, the cantilever 21 is arranged horizontally and made of rigid material. The first end of the cantilever 21 is connected to the upper surface of the weighing member 2, and the second end of the cantilever 21 is located inside the precipitation shell 1. The weighing member 2 is a weighing sensor, and it can also be other components that can detect weight, such as a weighing balance.

[0038] The filler frame 3 is arranged movably up and down in the precipitation shell 1 to adapt to changes in the water level in the precipitation shell 1. The filler frame 3 is provided with a filler layer 4 composed of filler. The specific material of the filler is known in the art and will not be described here. The filler frame 3 includes a peripheral side wall 31 and a bottom wall 32 connected to the lower end of the peripheral side wall 31. A plurality of spaced-apart water inlet holes (not shown in the figure) are arranged on the bottom wall 32, and the filler cannot leak through the water inlet holes. Specifically, the filler frame 3 is a frame made of metal with an open upper end forming a drainage outlet. The bottom of the frame is made of a mesh metal plate, and the mesh holes of the mesh metal plate form water inlet holes. A sealing member is arranged between the peripheral side wall 31 and the side wall of the precipitation shell 1 to seal the gap between the filler frame 3 and the precipitation shell 1, so that water can only be discharged after being filtered by the filler layer 4. Each cantilever 21 is connected to the upper end of the peripheral side wall 31 through an elastic connecting member 211. Specifically, the first end of the elastic connecting member 211 is connected to the second end of the cantilever 21, and the second end of the elastic connecting member 211 is connected to the upper end of the peripheral side wall 31. That is, the filler frame 3 is suspended in the precipitation shell 1 by a plurality of spaced-apart cantilevers 21. The cantilevers 21 can bear the weight of the filler frame 3 and transmit the weight to the weighing members 2. The weighing members 2 can measure the weight transmitted by the cantilevers 21 in real time. The connection of the cantilevers 21 and the filler frame 3 through the elastic connecting members 211 allows the filler frame 3 to be suspended in the precipitation shell 1 without affecting the up-and-down movement of the filler frame 3 relative to the precipitation shell 1.

[0039] The level 5 is connected to the upper end of the peripheral side wall 31, specifically, the level 5 is connected to the upper end of the peripheral side wall 31 through a connecting rod, and the level 5 is located outside the sediment shell 1, when the filler layer 4 is blocked by the sludge, the weight of the filler layer 4 changes, on the one hand, the weight of the filler frame 3 causes the elastic connecting piece 211 to deform, and the filler frame 3 is displaced in the vertical direction, so that the level 5 changes, by observing the change of the level 5, the staff can find the sludge blockage and determine the blockage direction in time, on the other hand, the weight of the filler frame 3 changes the weight of the load cell 2 through the cantilever 21, by comparing the initial measurement result of the load cell 2 with the real-time measurement result, the weight of the sludge causing the blockage can be obtained, so that the staff can clean the filler layer 4 in time, thereby effectively avoiding the deformation and even collapse of the filler layer.

[0040] The sedimentation device of the present application can find the sludge blockage of the filler layer 4 and determine the blockage direction in time by observing the change of the level 5, by comparing the initial measurement result of the load cell 2 with the real-time measurement result, the weight of the sludge causing the blockage can be obtained, so that the staff can clean the filler layer 4 in time, thereby prolonging the service life of the filler layer 4.

[0041] Further, the cross-sectional shape of the filler frame 3 is the same as that of the sediment shell 1, so that the filler layer 4 in the filler frame 3 can filter the water in the sediment shell 1 with the maximum area, preferably, the cross-section of the filler frame 3 and the cross-section of the sediment shell 1 are both rectangular, of course, the cross-section of the filler frame 3 and the cross-section of the sediment shell 1 can also be both circular or elliptical, which will not be described here.

[0042] Of course, the cross-sectional shape of the filler frame 3 can also be different from that of the sediment shell 1, for example, the cross-section of the filler frame 3 is rectangular, and the cross-section of the sediment shell 1 is elliptical, or the cross-section of the filler frame 3 is elliptical, and the cross-section of the sediment shell 1 is rectangular, which will not be described here.

[0043] Further, as shown in Figure 1 The load indicator 22 is connected to the load cell 2, the load indicator 22 can directly display the measurement result of the load cell, so that the operation of obtaining the measurement result of the load cell 2 is simple and convenient, wherein the specific structure of the load indicator 22 and its working principle are both prior art, which will not be described in detail here.

[0044] Further, as shown in Figure 1As shown, the seal is at least one follow-up sealing ring plate 33 sleeved on the outer part of the peripheral wall 31, the outer circumferential surface of the follow-up sealing ring plate 33 is sealingly attached to the inner surface of the sediment housing 1, and the follow-up sealing ring plate 33 can move up and down with the filler support 3, so that the follow-up sealing ring plate 33 can play a sealing role and will not affect the movement of the filler support 3, thereby ensuring the accuracy of the detection result of the level meter 5.

[0045] Further, as shown in the drawings, Figure 2 The outer part of the peripheral wall 31 is sleeved with two follow-up sealing ring plates 33, and the two follow-up sealing ring plates 33 are located at the upper and lower ends of the peripheral wall 31. The arrangement of the two follow-up sealing ring plates 33 can effectively ensure the sealing between the filler support 3 and the sediment housing 1, thereby ensuring that the water discharged by the sedimentation device is filtered water.

[0046] Further, the elastic connecting piece 211 is a tension spring, which can bear axial tension and restore after losing force, so that the filler support 3 can return to the horizontal state after the filler layer 4 is cleaned.

[0047] Of course, the elastic connecting piece 211 can also use other elastic components, such as rubber.

[0048] In an embodiment of the present application, as shown in the drawings, Figure 1 and Figure 2 The extension end of each cantilever 21 is connected with a scale 6, and the upper end of the peripheral wall 31 is connected with a plurality of pointers 7 corresponding to each scale 6. Among them, the scale 6 and the pointer 7 are vertically arranged. When the filler layer 4 is blocked, the weight of the filler support 3 will increase, and the weight increase of the filler support 3 will cause the elastic connecting piece 211 to deform, causing the filler support 3 to displace in the vertical direction. The displacement of the filler support 3 will change the position of the pointer 7 pointing to the scale 6. By observing the change of the pointer 7 and combining the detection result of the level meter 5, the blocked position can be accurately determined.

[0049] Further, the upper end of the sediment housing 1 is connected with four equally spaced weighing members 2, the upper surface of each weighing member 2 is connected with a cantilever 21, and the extension end of each cantilever 21 is connected with a scale 6. Correspondingly, the upper end of the peripheral wall 31 is connected with four equally spaced pointers 7, that is, one pointer 7 corresponds to one scale 6. Such an arrangement can indicate the blocked position without affecting the discharge of water.

[0050] In an embodiment of the present application, as shown in the drawings, Figure 1 and Figure 2As shown, the sedimentation shell 1 comprises a filtering area 11 and a sludge discharge area 12 arranged in sequence from top to bottom, the filler frame 3 is arranged in the filtering area 11, the inner surface of the sedimentation shell 1 is connected with a lower limit ring plate 13 at the position corresponding to the bottom of the filtering area 11, the lower end surface of the peripheral side wall 31 can abut against the top surface of the lower limit ring plate 13, the lower limit ring plate 13 can effectively prevent the filler frame 3 from moving downward to the sludge discharge area 12, preferably, the water inlet is arranged between the top end of the sludge discharge area 12 and the lower limit ring plate 13, the filler frame 3 is limited from blocking the water inlet by the lower limit ring plate 13, so that the water to be treated can smoothly enter the sedimentation shell 1 through the water inlet.

[0051] Further, the sludge discharge area 12 is conical with the upper part being larger and the lower part being smaller, so that the sludge can move along the side wall of the sedimentation shell 1 to the bottom of the sludge discharge area 12 under the automatic gravity, preferably, a sludge discharge port is arranged at the bottom of the sludge discharge area 12, so that the operation of cleaning the sludge is simple and convenient.

[0052] The use process of the sedimentation device will be specifically described below in combination with the drawings:

[0053] As shown in Figure 1 and Figure 2 the water to be filtered is introduced from the water inlet between the lower limit ring plate 13 and the upper end of the sludge discharge area 12, after being filtered by the filler layer 4 in the filler frame 3, the filtered water is discharged through the outlet, the precipitated sludge falls to the bottom of the sludge discharge area 12 under the action of its own gravity and can be discharged through the sludge discharge port arranged at the bottom of the sludge discharge area 12, when the filler layer 4 is blocked, the weight of the filler will change, the weight increase of the filler frame 3 will cause the elastic connecting piece 211 to deform and the filler frame 3 to displace in the vertical direction, if the filler is unevenly blocked, the relative displacement in the direction where the blockage is more serious will be larger, so that the filler frame 3 will be more seriously tilted, thereby causing the change of the flatness of the level meter 5 and the obvious change of the relative position between the corresponding pointer 7 and the scale 6, in the normal use process, by frequently observing the relative position between the pointer 7 and the scale 6 and the condition of the level meter 5, the filler blockage can be found in time and the blockage direction can be determined, at the same time, by comparing the initial measurement result with the real-time measurement result of the weighing member 2, the weight of the sludge causing the blockage can be obtained, and the staff can clean the filler layer 4 in time according to the weight of the sludge causing the blockage.

[0054] In summary, the sedimentation device can find the filler blockage in time and determine the blockage direction by observing the flatness change of the level meter and the displacement condition of the corresponding pointer relative to the scale, and the weight of the sludge causing the blockage can be obtained by comparing the initial measurement result with the real-time measurement result of the weighing member, so that the staff can clean the filler layer in time to prolong the service life of the filler layer.

[0055] The precipitation device of the present application is simple and convenient in operation for obtaining the measurement result of the weighing member 2 by arranging the weight indicator.

[0056] The above merely illustrates the specific embodiments of the present application, and is not intended to limit the scope of the present application. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present application shall fall within the scope of the present application. It should be noted that the components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be selected for single use or combined use, and therefore, the present application naturally covers other combinations and specific applications related to the present application.
