Description

Technical Field

[0001] The present invention relates to the technical field of cryogenic coolers, and more particularly to a dynamically adjustable cryogenic cooler for a pressure vessel. Background Art

[0002] Cooler is a type of heat exchange equipment used to cool fluids, usually using water or air as a coolant to remove heat. There are wall coolers, spray coolers, jacket coolers, and coil coolers. The low-temperature polytetrafluoroethylene cooler for power plants is a new type of device used by power plants to reduce the exhaust temperature and recover waste heat.

[0003] In the prior art, the dynamically adjustable low-temperature cooler for pressure vessels usually places a heat exchange tube on the outer side of the pressure vessel during use, and controls the cooling of the pressure vessel by cooling the outer surface of the pressure vessel. In actual use, it is necessary to adjust the cooling temperature of the cooler according to the requirements of the pressure vessel, and usually the control effect is achieved by controlling the temperature of the cooling water. However, the current control means are relatively limited, and only the method of controlling the cooling water temperature is used. When the temperature needs to be adjusted back, the target temperature of the coolant cannot be quickly restored, the actual adjustment speed is slow, and the use effect is not good. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a dynamically adjustable low-temperature cooler for a pressure vessel, which has the advantages of improving the cooling and regulating effect and convenient filtering treatment.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a dynamically adjustable low-temperature cooler for a pressure vessel, comprising a pressure vessel, a heat exchange frame fixedly connected to the outer surface of the pressure vessel, a control frame sleeved inside the heat exchange frame, a fixed pipe fixedly connected to the top surface of the heat exchange frame, a sealing plate provided inside the fixed pipe, a connecting rod fixedly connected to the bottom surface of the sealing plate, an inner end of the connecting rod passes through the heat exchange frame and is fixedly connected to the control frame, a pull rod fixedly connected to the top surface of the sealing plate, a No. 1 spring fixedly connected to the top surface of the sealing plate, a bottom frame fixedly installed on the bottom surface of the pressure vessel, a connecting pipe fixedly connected to the end surface of the heat exchange frame, a connecting pipe fixedly connected to the end surface of the connecting pipe, a connecting frame fixedly connected to the side surface of the connecting frame, and a water inlet pipe fixedly connected to the side surface of the water inlet pipe.

[0006] As a preferred technical solution of the present invention, a fixing rod is fixedly connected to the top surface of the heat exchange frame, a transverse plate is movably sleeved on the outer surface of the fixing rod, and the transverse plate is fixedly connected to the pull rod.

[0007] By using the transverse plate to symmetrically connect the two groups of left and right fixing rods, when the control frame is actually moved and adjusted, the hollow control frame is guaranteed to move stably, and the asymmetry between the left and right sides is avoided to cause jamming.

[0008] As a preferred technical solution of the present invention, an adjusting cap is threadedly sleeved on the outer surface of the fixing rod, and the adjusting cap is located on the outer side of the transverse plate.

[0009] By utilizing the threaded connection between the adjusting cap and the fixing rod, the adjusting cap can be directly rotated to push the cross plate to move. With the compression of the No. 1 spring, the movement and adjustment of the control frame can be achieved, and the elasticity of the No. 1 spring can be used to quickly reset when it is rotated outward, which makes the adjustment convenient.

[0010] As a preferred technical solution of the present invention, the end face of the water inlet pipe is threadedly sleeved with a sealing cover, the front face of the sealing cover is movably sleeved with an adjusting rod, the inner end face of the adjusting rod is fixedly connected to a filter plate, and the side of the filter plate is provided with filter holes.

[0011] By utilizing the threaded sleeve connection between the sealing cover and the water inlet pipe, the filter plate can be conveniently taken out when the sealing cover is screwed out, thereby facilitating cleaning and maintenance.

[0012] As a preferred technical solution of the present invention, a round rod is fixedly connected to the interior of the communication frame, the round rod is located inside the water inlet pipe, the diameter of the round rod is smaller than the inner diameter of the filter hole, and the round rod and the filter hole correspond one to one.

[0013] By utilizing a round rod with a diameter slightly smaller than the inner diameter of the filter hole, and when the adjusting rod is pushed to move, the filter holes on the aligned filter plates are sleeved with the round rod, thereby squeezing out the blockages in the filter holes and achieving a quick and convenient clearing operation.

[0014] As a preferred technical solution of the present invention, the outer end surface of the adjusting rod is fixedly connected with a side plate, and a No. 2 spring is fixedly connected between the side plate and the sealing cover, and the No. 2 spring is located on the outer side of the adjusting rod.

[0015] By utilizing the elasticity of the No. 2 spring, after pressing the adjustment rod to move, when the filter hole is cleared, the side plate can be loosened to utilize the elasticity of the No. 2 spring to achieve rapid reset.

[0016] As a preferred technical solution of the present invention, the number of the heat exchange frames is six, and the six heat exchange frames are grouped into two groups, which are divided into left and right groups. The two groups of heat exchange frames are symmetrically distributed on the left and right sides of the pressure vessel.

[0017] By utilizing symmetrically distributed heat exchange frames, the surface of the pressure vessel is cooled from both sides, thereby reducing the internal temperature of the pressure vessel.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention adds a control frame inside the heat exchange frame to ensure that the interior of the control frame is a central hole, and the control frame is made of insulating material. A connecting rod is fixedly installed on the outer side of the control frame, and a fixed pipe is installed on the top surface of the heat exchange frame, so that the connecting rod is connected to the pull rod through a sealing plate. In the actual adjustment process, the movement of the pull rod is achieved by changing the position of the cross plate, so that the control frame located in the heat exchange frame gradually fits onto the outer surface of the pressure vessel. A hollow control frame is used to increase the actual heat exchange distance, and a control frame made of insulating material is used to achieve mechanical adjustment, thereby increasing the heat exchange distance of cooling water. When recovery is required, the control frame can be pulled to reset, thereby achieving instant recovery and achieving good adjustment effect.

[0020] 2. The present invention fixes a connecting side pipe on the side of the water inlet pipe, and threads a sealing cover on the end face of the metal pipe, so that the end face of the sealing cover can be movably sleeved with an adjusting rod, and the inner end face of the adjusting rod is fixedly connected to a filter plate, and a round rod is added inside the connecting frame so that the diameter of the round rod is smaller than the inner diameter of the filter hole. During the filtering process, the filter hole on the filter plate can be passed along the round rod by pressing the adjusting rod and driving the filter plate to move, thereby cleaning the blockage. After the blockage is cleared, the sealing cover can be disassembled for cleaning and maintenance, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 5 As shown, the present invention provides a dynamically adjustable low temperature cooler for a pressure vessel, comprising a pressure vessel 1, a heat exchange frame 3 is fixedly connected to the outer surface of the pressure vessel 1, a control frame 8 is sleeved inside the heat exchange frame 3, a fixed pipe 7 is fixedly connected to the top surface of the heat exchange frame 3, a sealing plate 10 is provided inside the fixed pipe 7, a connecting rod 9 is fixedly connected to the bottom surface of the sealing plate 10, the inner end of the connecting rod 9 passes through the heat exchange frame 3 and is fixedly connected to the control frame 8, the control frame 8 is a sealing frame with a hollow interior, and in accordance with the properties of the heat insulating material, when the control frame 8 is moved to contact the surface of the pressure vessel, the heat exchange frame 8 is enlarged. 3 The heat exchange distance between the internal cooling water and the pressure vessel is changed, thereby changing the cooling effect. The top surface of the sealing plate 10 is fixedly connected with a pull rod 12. The diameter of the sealing plate 10 is slightly smaller than the inner diameter of the fixed pipe 7 to ensure a certain sealing performance while moving to avoid leakage. The top surface of the sealing plate 10 is fixedly connected with a spring 11. The bottom surface of the pressure vessel 1 is fixedly installed with a bottom frame 2. The end surface of the heat exchange frame 3 is fixedly connected with a connecting pipe 4. The end surface of the connecting pipe 4 is fixedly connected with a connecting frame 5. The side of the connecting frame 5 is fixedly connected with a water inlet pipe 6. The side of the water inlet pipe 6 is fixedly connected with a side pipe 16.

[0029] The top surface of the heat exchange frame 3 is fixedly connected with a fixing rod 14 , the outer surface of the fixing rod 14 is movably sleeved with a transverse plate 13 , and the transverse plate 13 is fixedly connected with the pull rod 12 .

[0030] By using the transverse plate 13 to symmetrically connect the left and right sets of fixing rods 14, when the control frame 8 is actually moved and adjusted, the hollow control frame 8 is guaranteed to move stably to avoid jamming due to left-right asymmetry.

[0031] The outer surface of the fixing rod 14 is threadedly sleeved with an adjusting cap 15 , and the adjusting cap 15 is located outside the transverse plate 13 .

[0032] By utilizing the threaded connection between the adjusting cap 15 and the fixing rod 14, the adjusting cap 15 can be directly rotated to push the cross plate 13 to move. With the compression of the No. 1 spring 11, the movement and adjustment of the control frame 8 can be achieved, and the elasticity of the No. 1 spring 11 can be used to quickly reset when it is screwed out, so the adjustment is convenient.

[0033] The end face of the water inlet pipe 6 is threadedly sleeved with a sealing cover 17, the front face of the sealing cover 17 is movably sleeved with an adjusting rod 18, the inner end face of the adjusting rod 18 is fixedly connected with a filter plate 19, and the side face of the filter plate 19 is provided with filter holes 20.

[0034] By utilizing the sealing cover 17 to be threadedly sleeved with the water inlet pipe 6 , it is convenient to take out the filter plate 19 when the sealing cover 17 is actually screwed out, so as to facilitate cleaning and maintenance.

[0035] A round rod 23 is fixedly connected inside the communication frame 5 , and the round rod 23 is located inside the water inlet pipe 6 . The diameter of the round rod 23 is smaller than the inner diameter of the filter hole 20 , and the round rod 23 and the filter hole 20 correspond one to one.

[0036] By utilizing a round rod 23 whose diameter is slightly smaller than the inner diameter of the filter hole 20 and pushing the adjustment rod 18 to move, the filter hole 20 on the aligned filter plate 19 is sleeved with the round rod 23, thereby squeezing out the blockage in the filter hole 20 and achieving a quick and convenient clearing operation.

[0037] The outer end surface of the adjusting rod 18 is fixedly connected with a side plate 21 , and a No. 2 spring 22 is fixedly connected between the side plate 21 and the sealing cover 17 . The No. 2 spring 22 is located on the outer side of the adjusting rod 18 .

[0038] By utilizing the elasticity of the No. 2 spring 22 , after the adjustment rod 18 is pressed and moved, when the filter hole 20 is cleared, the side plate 21 can be loosened to achieve rapid reset by utilizing the elasticity of the No. 2 spring 22 .

[0039] There are six heat exchange frames 3 , and each of the six heat exchange frames 3 is grouped into two groups, which are divided into two groups on the left and right. The two groups of heat exchange frames 3 are symmetrically distributed on the left and right sides of the pressure vessel 1 .

[0040] By utilizing the symmetrically distributed heat exchange frames 3, the surface of the pressure vessel is cooled from both the left and right sides, thereby reducing the internal temperature of the pressure vessel.

[0041] The working principle and use process of the present invention are as follows: when it is necessary to reduce the cooling effect, the adjusting cap 15 is rotated so that the adjusting cap 15 pushes the horizontal plate 13 to move, and then the pull rod 12 drives the sealing plate 10 and the connecting rod 9 to move, so that the connecting rod 9 drives the control frame 8 to move along the inside of the heat exchange frame 3 and contact the surface of the pressure vessel, so that the distance between the cooling water and the pressure vessel is increased, and the surface cooling rate of the pressure vessel is reduced. When the cooling temperature needs to be restored, the adjusting cap 15 is rotated, and the control frame 8 is reset with the push of the No. 1 spring 11; when it is necessary to clear the blockage, the side plate 21 is pressed, so that the side plate 21 pushes the No. 2 spring 22 to compress, and the adjusting rod 18 drives the filter plate 19 to move, so that the round rod 23 is connected with the filter hole 20, so that the blockage in the filter hole 20 is pushed out. When the blockage needs to be further cleared, the sealing cover 17 is unscrewed and the adjusting rod 18 and the filter plate 19 are taken out.
