Abstract
Description
Technical Field
[0001] This utility model relates to the field of hole technology, specifically a conical manhole. Background Technology
[0002] A manhole is a type of passageway structure, primarily used for workers to enter and exit large containers (such as oil tanks and boilers), pipelines (such as sewers and communication / weak current wells), or enclosed spaces (such as internal passages of bridges) for installation, maintenance, cleaning, and other operations.
[0003] In addition to serving as passageways for staff, manholes can also be used for ventilation, lighting, and material discharge outlets (such as discharge outlets for equipment like mixing tanks, evaporators, or three-in-one filters).
[0004] When used as a material outlet, material often gets stuck in the manhole, causing localized accumulation. For example, if material gets stuck in the manhole of a mixing vessel, it will cause uneven mixing and affect the mixing effect. Similarly, if material gets stuck in the manhole of an evaporator, it will cause accumulation and affect the evaporation effect. Utility Model Content
[0005] In view of the above-mentioned shortcomings in the related technologies, the purpose is to provide a conical manhole to solve the technical problem that material gets stuck in the manhole, causing local accumulation of material.
[0006] The technical solution to achieve the objective is: a conical manhole, comprising:
[0007] A fastener, one end of which is connected to the equipment tank, the fastener is in communication with the equipment tank, and the inner wall of the fastener has a first conical surface;
[0008] A detachable component is inserted into the fixing component, with one end connected to the other end of the fixing component. The outer wall of the detachable component has a second conical surface, and the other end of the detachable component has a concave arc-shaped surface. The second conical surface fits into the first conical surface, and the concave arc-shaped surface is flush with the inner wall of the equipment tank.
[0009] And at least one seal is attached to the outer wall of the detachable part, fits against the first conical surface, and is spaced apart from the equipment tank.
[0010] Furthermore: the fastener includes: a first tube, one end of which is connected to and communicates with the equipment tank;
[0011] And a flange, which is connected to the other end of the first pipe body.
[0012] Furthermore: the first tube is a section of circular tube with the first conical surface on its inner wall.
[0013] Furthermore: the detachable component includes: an insertion core having the second conical surface and the concave arcuate surface, the insertion core being used to insert into the fixing component, and the outer wall of the insertion core having at least one annular groove, the sealing component being disposed at the annular groove;
[0014] A cap is attached to the insert core for connection with the flange;
[0015] And two handles, spaced apart and connected to the end cap.
[0016] Furthermore: the insert core includes: a second tube, one end of which is connected to the end cap;
[0017] And a cover plate, connected to the other end of the second tube, having the concave arc-shaped surface.
[0018] Furthermore: the second tube is a section of circular tube, with the annular groove and the second conical surface on its outer wall.
[0019] Furthermore: the cover is a circular plate structure with several through holes spaced apart.
[0020] Furthermore, the through hole is a round hole.
[0021] Furthermore: the handle is a bent part with a "[" shaped structure.
[0022] Furthermore: the sealing element is an O-ring, which is disposed in the annular groove to form a seal between the fixed element and the detachable element.
[0023] The above technical solution has the following beneficial effects: a conical manhole, compared with related technologies, is provided with a fixing component, a detachable component and a sealing component;
[0024] One end of the fastener is connected to the equipment tank, and the seal is connected to the detachable part. The seal is inserted into the fastener together with the detachable part. The second conical surface on the detachable part fits with the first conical surface on the fastener, and the concave arc surface on the detachable part is flush with the inner wall of the equipment tank.
[0025] Because the second conical surface fits into the first conical surface, and the concave arc surface is flush with the inner wall of the equipment tank, the gaps between the fixed parts, detachable parts and the equipment tank after assembly are reduced, reducing the probability of material accumulating in the gaps. In addition, the sealing parts have a sealing effect, which reduces the probability of material getting stuck in the manhole and reduces the probability of material accumulation.
[0026] This overcomes the technical problem of materials getting stuck in the manhole, causing localized material accumulation. It reduces the probability of materials getting stuck in the manhole and the probability of material accumulation, thus demonstrating its practicality. Attached Figure Description

[0033] A conical manhole design solves the technical problem of material getting stuck in the manhole, causing localized material accumulation, in related technologies. This design can be manufactured and used, achieving the positive effects of reducing the probability of material getting stuck in the manhole and reducing the probability of material accumulation. The overall concept is as follows:
[0034] Implementation
[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; a conical manhole, comprising:
[0036] The fastener 10 has one end connected to the equipment tank 100 and communicates with the equipment tank 100. The fastener 10 also has a first conical surface 11 on its inner wall.
[0037] The detachable component 20 is inserted into the fixing component 10, with one end connected to the other end of the fixing component 10. The outer wall of the detachable component 20 has a second conical surface 21, and the other end of the detachable component 20 has a concave arc surface 22. The second conical surface 21 fits against the first conical surface 11, and the concave arc surface 22 is flush with the inner wall of the equipment tank 100.
[0038] And at least one sealing element 30, connected to the outer wall of the detachable part 20, fitting against the first conical surface 11, and spaced apart from the equipment tank 100;
[0039] Specifically, during implementation, one end of the fastener 10 is connected to the equipment tank 100, the seal 30 is connected to the detachable part 20, and the seal 30 is inserted into the fastener 10 together with the detachable part 20. The second conical surface 21 on the detachable part 20 fits against the first conical surface 11 on the fastener 10, and the concave arc surface 22 on the detachable part 20 is flush with the inner wall of the equipment tank 100.
[0040] Since the second conical surface 21 fits into the first conical surface 11, and the concave arc surface 22 is flush with the inner wall of the equipment tank 100, the gaps after the fastener 10, the detachable part 20 and the equipment tank 100 are assembled are reduced, which reduces the probability of material accumulating in the gaps. In addition, the sealing part 30 has a sealing function, which reduces the probability of material getting stuck in the manhole and reduces the probability of material accumulation.
[0041] Another implementation method:
[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in implementation, the fastener 10 includes: a first pipe body 10-1, one end of which is connected to and communicates with the equipment tank 100; and a flange 10-2, which is connected to the other end of the first pipe body 10-1;
[0043] The first pipe body 10-1 is a section of round pipe, one end of which is welded to the equipment tank 100. The first pipe body 10-1 is connected to the equipment tank 100, and the inner wall of the first pipe body 10-1 has a first conical surface 11. By fitting the first conical surface 11 with the second conical surface 21, not only is it relatively convenient to install and remove the detachable part 20, but also after fitting, the gap between the fixed part 10 and the detachable part 20 is relatively small, reducing the probability of material accumulating in the gap.
[0044] Flange 10-2 is welded to the first pipe body 10-1 for connection with end cap 20-2 via bolts, making installation and removal relatively convenient;
[0045] Another implementation method:
[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in implementation, the detachable component 20 includes: an insertion core 20-1, the insertion core 20-1 having a second conical surface 21 and a concave arc surface 22, the insertion core 20-1 being used to insert into the fixing component 10, and the outer wall of the insertion core 20-1 having at least one annular groove 20-11, at which the sealing component 30 is disposed; a cap 20-2, connected to the insertion core 20-1, for connecting to the flange 10-2; and two handles 20-3, spaced apart and connected to the cap 20-2;
[0047] The insert core 20-1 includes: a second tube 20-12, one end of which is connected to the end cap 20-2; and a cover plate 20-13, which is connected to the other end of the second tube 20-12 and has the concave arc-shaped surface 22.
[0048] The second tube body 20-12 is a section of circular tube, with the annular groove 20-11 and the second conical surface 21 on its outer wall;
[0049] The annular groove 20-11 is provided to facilitate the connection of the sealing element 30;
[0050] The second conical surface 21 is provided to fit with the first conical surface 11, making it relatively convenient to install and remove the detachable part 20. Moreover, after fitting, the gap between the fixing part 10 and the detachable part 20 is relatively small, reducing the chance of material accumulating in the gap.
[0051] The cover plate 20-13 is welded to the second pipe body 20-12, and the cover plate 20-13 has a concave arc surface 22. The concave arc surface 22 is flush with the inner wall of the equipment tank 100, so that the shape of the concave arc surface 22 is consistent with the inner wall of the equipment tank 100, which reduces the gap after the detachable part 20 and the equipment tank 100 are assembled, and reduces the probability of material accumulating in the gap.
[0052] The cover 20-2 is a circular plate structure with a plurality of through holes 20-21, which are spaced apart.
[0053] The through holes 20-21 are round holes, through which bolts are inserted to connect to the flange 10-2, making assembly and disassembly relatively convenient;
[0054] The handle 20-3 is a bent part with a "[" shaped structure. It is welded to the end cap 20-2, which is conducive to the grip of the staff and makes it easy to install and remove the detachable part 20. It is relatively convenient to use.
[0055] Another implementation method:
[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown; in practice, the sealing element 30 is an O-ring, which is set in the annular groove 20-11 to form a seal between the fixing element 10 and the detachable element 20, further forming a barrier, ensuring the sealing performance, and preventing material leakage.
[0057] Regarding equipment tank 100:
[0058] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The equipment tank 100 is a common structure in the prior art, such as the tank on a mixing vessel. It is roughly cylindrical in shape and has an arc-shaped surface on the inner wall (the concave arc surface 22 is consistent with the shape of the inner wall of the equipment tank 100, which reduces the gap between the detachable part 20 and the equipment tank 100 after assembly and reduces the probability of material accumulating in the gap). The equipment tank 100 is not the inventive point of this utility model. It is only used to better describe this utility model and facilitate the understanding of the technical solution of this utility model.
