Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, and particularly relates to a sewage sedimentation tank which is convenient for discharging mud. Background Art

[0002] Sewage purification is an important part of environmental protection and an important means to improve the living environment of human beings. With the intensification of human activities, more and more sewage and its types are generated, such as domestic sewage, industrial sewage, etc. Sedimentation tanks use the principle of natural sedimentation. Sewage is left to stand in it, and the insoluble impurities in the sewage settle to the bottom of the tank under the action of gravity to form sludge.

[0003] In the prior art, there are many different types of sewage sedimentation tanks. Most of the sedimentation tanks are just containers. When discharging mud, it is necessary to pump out the water in the sedimentation tank. A small number of sedimentation tanks are also equipped with mud discharge mechanisms, which can assist users to discharge mud when there is water in the tank. Common mud discharge mechanisms are mud discharge valves, mud pumps, and movable scrapers. Among them, when the mud discharge valve discharges mud, the sludge needs to pass through its interior, and there will inevitably be large-sized impurities in the sewage sediment (that is, the above-mentioned sludge). Large-sized impurities are easy to cause blockage or damage the internal structure of the mud discharge valve when passing through the mud discharge valve; when the mud pump and the movable scraper are discharging mud, they will disturb the sludge, causing part of the sludge to float up and mix into the sewage, resulting in incomplete mud discharge.

[0004] Therefore, we feel that the sewage sedimentation tanks that can assist in sludge discharge in the prior art still have technical problems of inconvenient and incomplete sludge discharge. Utility Model Content

[0029] Compared with the prior art, the utility model has the following beneficial effects:

[0030] The utility model provides a sewage sedimentation tank for facilitating sludge discharge, which comprises a tank body, a sealing plate, a partition plate and a translation driving assembly. The top and bottom of the tank body are penetrated to form an upper opening and a lower opening respectively. The upper opening is used to inject and discharge sewage. The tank body is also connected to a support frame so that the tank body is lifted off the ground. A through opening is provided at the lower part of the right side wall of the tank body. The sealing plate is detachably connected to the bottom of the tank body. The sealing plate blocks the lower opening. The partition plate can block the through opening. The partition plate is inserted in the through opening by sliding left and right, so that the through opening The opening is blocked, and a platform that can overlap the above-mentioned partition plate is provided inside the above-mentioned tank body. When the above-mentioned partition plate is inserted into the tank body and overlapped on the platform, the partition plate divides the internal space of the above-mentioned tank body into disconnected upper and lower chambers, and when the above-mentioned partition plate is pulled out from the internal space of the tank body, the above-mentioned upper and lower chambers are connected to form a complete chamber. A translation drive component is installed on the above-mentioned tank body, and a power output end of the translation drive component is connected to the above-mentioned partition plate. Therefore, the translation drive component can drive the above-mentioned partition plate to translate in the through-opening.

[0031] When the sewage settling tank does not need to discharge mud, the partition plate is driven to move to the rightmost end by the translation drive assembly.

DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0053] Embodiment 1:

[0054] like Figure 1-Figure 16 As shown, the sewage sedimentation tank for facilitating sludge discharge provided in this embodiment includes a tank body 1, a sealing plate 3, a partition plate 4 and a translation drive assembly, wherein:

[0055] The top and bottom of the tank body 1 are penetrated to form an upper opening and a lower opening respectively. Optionally, the tank body 1 is a square straight cylinder structure, and the upper opening is used to inject sewage to be precipitated and discharge sewage obtained after precipitation. The tank body 1 is also connected to a support frame 2, so that the tank body 1 is lifted off the ground. A through opening is opened at the lower part of the right side wall of the tank body 1.

[0056] The sealing plate 3 is detachably connected to the bottom of the tank body 1, and the sealing plate 3 blocks the lower opening. At this time, the sealing plate 3 and the tank body 1 form a container, and the sewage is statically settled in the container, and the undissolved impurities in the sewage are settled on the sealing plate 3 and the bottom of the tank body 1.

[0057] The partition plate 4 can block the through-hole, and the partition plate 4 is inserted into the through-hole by sliding left and right, so that the through-hole is blocked to prevent water leakage from the through-hole. A platform that can overlap the partition plate 4 is provided inside the tank body 1. When the partition plate 4 is inserted into the tank body 1 and overlapped on the platform, the partition plate 4 divides the internal space of the tank body 1 into a disconnected upper chamber and a lower chamber, and when the partition plate 4 is pulled out from the tank body 1, the upper chamber and the lower chamber are connected to form a complete chamber. It should be noted that although the partition plate 4 is pulled out from the tank body 1, the partition plate 4 is still inserted in the through-hole. In this way, when mud discharge is not required, the partition plate 4 is pulled out from the tank body 1 and the left end of the partition plate 4 is placed in the through-hole. When mud discharge is required, the partition plate 4 is inserted into the tank body 1 and the partition plate 4 is overlapped on the platform.

[0058] The translation drive assembly is installed on the above-mentioned tank body 1, and the power output end of the translation drive assembly is connected to the above-mentioned partition plate 4. Therefore, the translation drive assembly can drive the above-mentioned partition plate 4 to translate in the through-hole so that the partition plate 4 can be inserted into or pulled out of the interior of the above-mentioned tank body 1.

[0059] When the sewage settling tank does not need to discharge mud, the partition plate 4 is driven to move to the rightmost end by the translation drive assembly. At this time, the partition plate 4 is withdrawn from the interior of the tank body 1, but the partition plate 4 is still placed in the through-hole to block the through-hole. In this case, the interior of the tank body 1 constitutes a complete chamber, and the insoluble impurities in the sewage are precipitated on the sealing plate 3 located at the bottom of the tank body 1. When it is necessary to discharge mud, the partition plate 4 is driven to move to the leftmost end by the translation drive assembly. At this time, the partition plate 4 is inserted into the interior of the tank body 1 to separate the internal space of the tank body 1 into an upper chamber and a lower chamber that are disconnected, and the partition plate 4 is overlapped on the platform inside the tank body 1, so that the partition plate 4 has a stronger load-bearing capacity. The upper chamber above the partition plate 4 is sewage without impurities, and the chamber below the partition plate 4 is sludge precipitated from the sewage. At this time, it is only necessary to remove the sealing plate 3 from the tank body 1, and then clean the sealing plate 3 and the sludge on the lower inner wall of the tank body 1.

[0060] Through the above structure, the sewage sedimentation tank provided in this embodiment uses the above-mentioned partition plate 4 to form a disconnected upper chamber and a lower chamber inside the tank body 1 when discharging sludge. The sealing plate 3 can be removed to conveniently and thoroughly remove and discharge the sludge settled at the bottom of the tank body 1. Due to the barrier effect of the partition plate 4, the sludge in the sludge discharge process will not float up to the sewage in the upper chamber, and there is no need to extract the sewage in the tank body 1 when discharging sludge. The sewage sedimentation tank with this structure is not easily blocked by sludge during use.

[0061] Optionally, the lower part of the left side wall, the front side wall and the rear side wall of the above-mentioned tank body 1 are all integrally formed with a boss 101, and the boss 101 can increase the wall thickness of the corresponding part of the tank body 1. The position of the above-mentioned boss 101 on the tank body 1 corresponds to the above-mentioned through-opening, that is, the boss 101 and the through-opening are at the same height. A slide groove 102 is provided on the above-mentioned boss 101, and the above-mentioned slide groove 102 is connected to the interior of the above-mentioned tank body 1, and the slide groove 102 corresponds to the above-mentioned through-opening. The bottom of the above-mentioned slide groove 102 constitutes the above-mentioned platform. When mud discharge is required, when the above-mentioned partition plate 4 is inserted into the above-mentioned tank body 1, the partition plate 4 is actually slidably inserted into the above-mentioned slide groove 102, so that the bottom of the slide groove 102 is supported below the partition plate 4 to support the partition plate 4. The chute 102 of the boss 101 on the left side of the tank body 1 is defined as the left notch, the chute 102 of the boss 101 on the front side of the tank body 1 is defined as the front notch, and the chute 102 of the boss 101 on the rear side of the tank body 1 is defined as the rear notch. Optimally, when discharging mud, the left end of the partition plate 4 is inserted into the left notch and abuts against the groove wall of the left notch, the rear end of the partition plate 4 is inserted into the rear notch and abuts against the groove wall of the rear notch, and the front end of the partition plate 4 is inserted into the front notch and abuts against the groove wall of the front notch. In this way, when discharging mud, the partition plate 4 divides the internal space of the tank body 1 into disconnected upper and lower chambers, and the gravity of the sewage is applied to the partition plate 4, which can also press the partition plate 4 on the groove bottom of the chute 102.

[0062] Optionally, the translation drive assembly includes a connecting frame 6 and an electric telescopic rod 5 with a telescopic shaft. A mounting plate 103 is provided on the left outer wall of the tank body 1, and the electric telescopic rod 5 is mounted on the mounting plate 103. Of course, a power supply is also included to energize the electric telescopic rod 5. The connecting frame 6 is connected between the telescopic shaft and the partition plate 4. The telescopic direction of the electric telescopic rod 5 is left and right, so that when the telescopic shaft of the electric telescopic rod 5 is extended and retracted, the partition plate 4 can be driven to translate left and right through the connecting frame 6. When the partition plate 4 moves to the rightmost end, the partition plate 4 is in a state of being pulled out from the inside of the tank body 1, and the left end of the partition plate 4 is placed in the through opening; when the partition plate 4 moves to the leftmost end, the partition plate 4 is in a state of being inserted into the inside of the tank body 1, and the partition plate 4 divides the internal space of the tank body 1 into disconnected upper and lower chambers.

[0063] In order to make the partition plate 4 and the connecting frame 6 move left and right more smoothly, two slideways 61, one in front and one in the back, are provided on the connecting frame 6. The boss 101 on the front side wall of the tank body 1 is slidably inserted into the slideway 61 on the front side of the connecting frame 6, and the boss 101 on the rear side wall of the tank body 1 is slidably inserted into the slideway 61 on the rear side of the connecting frame 6.

[0064] More preferably, a shielding plate 7 is installed between the left outer walls of the tank body 1 , and the shielding plate 7 can cover the electric telescopic rod 5 , thereby shading the electric telescopic rod 5 from the sun and rain.

[0065] An optional implementation of this embodiment is as follows: a wing plate 104 is fixed on the outer wall of the bottom end of the tank body 1, the support frame 2 is welded to the wing plate 104, the sealing plate 3 is bolted and fixed to the wing plate 104 by bolts 8, and it is convenient to disassemble and assemble. In addition, a first sealing ring 9 is installed between the sealing plate 3 and the wing plate 104. Specifically, the first sealing ring 9 is bonded and fixed to the bottom surface of the wing plate 140. When the sealing plate 3 is installed on the wing plate 104, the sealing plate 3 is pressed against the first sealing ring 9, so that the gap between the sealing plate 3 and the wing plate 104 is sealed by the first sealing ring 9. Specifically, when mud discharge is not required, the sealing plate 3 is connected to the wing plate 104, and the sealing plate 3 and the wing plate 104 are sealed by means of the first sealing ring 9 to prevent water leakage from the gap between the sealing plate 3 and the wing plate 104.

[0066] In order to further improve the bearing capacity of the sealing plate 3, in this embodiment, a jack 10 is further installed below the sealing plate 3, and the top of the jack 10 is connected to the sealing plate 3, so that the jack 10 is used to support the sealing plate 3 when the mud is not discharged. When discharging mud, the bolts 8 connecting the sealing plate 3 and the wing plate 104 are first removed, and then the jack 10 is driven to retract, and the sealing plate 3 is lowered together with the top of the jack 10 until the mud on the sealing plate 3 is completely exposed from the tank body 1. After the mud is cleaned, the jack 10 is driven to extend and the sealing plate 3 is supported on the bottom end of the tank body 1 by the jack 10, and then the bolts 8 are installed to lock it.

[0067] An optional implementation of the present embodiment is as follows: a ring 105 surrounding the through-hole is integrally formed on the right outer wall of the tank body 1, and the partition plate 4 is slidably inserted into the inner hole of the ring 105 left and right, and a second sealing ring 11 is installed between the ring 105 and the partition plate 4. With the help of the second sealing ring 11, the gap between the partition plate 4 and the ring 105 can be better sealed, thereby avoiding water leakage from the through-hole.

[0068] Optionally, the second sealing ring 11 includes a rubber ring 111 and two rubber plates 112, wherein the rubber ring 111 is bonded and fixed to the inner wall of the ring 105, the two rubber plates 112 are integrally formed and arranged on one end face of the rubber ring 111, and the rubber plates 112 are located outside the ring 105. The partition plate 4 in this embodiment includes a horizontal plate 41 and a vertical plate 42, the horizontal plate 41 is connected to the middle of the vertical plate 42, and the horizontal plate 41 is inserted into the through opening and the rubber ring 111, the two rubber plates 112 are respectively located above and below the horizontal plate 41, and the vertical plate 42 is placed outside the ring 105. When discharging mud, the partition plate 4 is inserted into the interior of the tank body 1 (actually, the horizontal plate 41 is inserted into the interior of the tank body 1) and the internal space of the tank body 1 is divided into a disconnected upper chamber and a lower chamber, and the vertical plate 42 presses the two rubber plates 112 tightly against one end face of the ring 105. With the aid of the above structure, the rubber ring 111 seals the gap between the ring 105 and the horizontal plate 41, and when discharging mud, the two rubber plates 112 can seal the gap between the ring 105 and the vertical plate 42, thereby better preventing water leakage when discharging mud.

[0069] More preferably, the sewage sedimentation tank provided in this embodiment also includes two pressure plates 12, and both pressure plates 12 are detachably connected to the above-mentioned ring ring 105. Specifically, when the mud is discharged, the two pressure plates 12 are removed. When the mud is not discharged, the pressure plates 12 are installed on the ring ring 105, and the two pressure plates 12 are respectively located above and below the above-mentioned transverse plate 41. The pressure plate 12 located above the transverse plate 41 is defined as the upper pressure plate, and the pressure plate 12 located below the transverse plate 41 is defined as the lower pressure plate. When the mud is not discharged, that is, when the transverse plate 41 of the partition plate 4 is pulled out from the inside of the tank body 1, the rubber plate 112 located above the above-mentioned transverse plate 41 is pressed against the top surface of the transverse plate 41 through the upper pressure plate, and the rubber plate 112 located below the transverse plate 41 is pressed against the bottom surface of the transverse plate 41 through the lower pressure plate. In this way, it can better prevent water leakage when mud is not discharged, and the pressure plate 12 presses the rubber plate 112 against the surface of the horizontal plate 41, and can also act as a brake on the horizontal plate 41, so that the partition plate 4 is more firmly placed in the through-hole when mud is not discharged.

[0070] Specifically, a stud 106 is provided on the outer wall of the ring 105, a connecting plate 121 is provided on the pressing plate 12, a through hole is provided on the connecting plate 121, the stud 106 is inserted into the through hole, and a nut 13 for pressing the connecting plate 121 onto the ring 105 is also screwed on the stud 106. When mud is not discharged, the nut 13 is tightened, and the nut 13 presses the connecting plate 121 onto the ring 105, so that the pressing plate 12 presses the rubber plate 112 onto the surface of the horizontal plate 41; when mud is required to be discharged, the nut 13 is unscrewed and the mounting plate 103 is removed, and then the electric telescopic rod 5 is used to drive the partition plate 4 to move to the left, so that the horizontal plate 41 of the partition plate 4 divides the internal space of the tank body 1 into a disconnected upper chamber and a lower chamber.

[0071] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model.
