Description

Technical Field

[0001] This utility model relates to the field of chilled brine pipeline technology, specifically a chilled brine pipeline that can reduce cold loss. Background Technology

[0002] A brine chiller is an industrial refrigeration device that uses a brine solution (such as calcium chloride or sodium chloride solution) as a refrigerant. It is widely used in industries requiring low-temperature environments, such as pharmaceuticals, chemicals, food processing, and photovoltaics. Its core function is to cool brine to the target temperature (-40℃ to 0℃) through a refrigeration cycle system, and then use a circulating pump to deliver the low-temperature brine to the equipment being cooled, thereby achieving process cooling or temperature control.

[0003] In some existing brine chillers, the brine has a long contact time with the pipes when guiding it, resulting in some temperature loss due to conduction. Furthermore, some existing pipes are prone to turbulence, which reduces the brine flow rate and further accelerates temperature loss, thus reducing the suitability of the pipes. Utility Model Content

[0004] The purpose of this invention is to provide a chilled brine pipe that can reduce cold loss, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chilled brine pipe that can reduce cold loss, comprising a connecting pipe and mounting holes formed on its surface, and further comprising:

[0006] An insulation plate is provided on the surface of the connecting pipe. A guide plate that generates a vortex in the brine by means of its shape is fixedly connected to the upper part of the inner cavity of the connecting pipe. A flow guide frame that enables the brine to rotate continuously by means of its shape to increase the flow rate is fixedly connected to the bottom of the guide plate.

[0007] An auxiliary mechanism installed below the inner cavity of the connecting pipe reduces the flow rate by separating the brine. The connecting pipe is fixedly connected to a drag-reducing plate that reduces the friction between the brine and the inner wall of the connecting pipe by means of its position and arrangement.

[0008] Preferably, the auxiliary mechanism includes a connecting plate fixed to the inner wall of the connecting pipe, a positioning pipe fixedly connected to one side of the connecting plate, and a guide groove formed on the inner wall of the positioning pipe.

[0009] Preferably, there are several guide plates, all of which are arranged in a ring array around the center of the connecting pipe, and the guide plates are designed with an inclined structure.

[0010] Preferably, the flow guide has a spiral structure design, and there are three flow guides, all of which are used in conjunction with the guide plate.

[0011] Preferably, the number of the resistance-reducing plates is several, and the upper resistance-reducing plates and the lower ones are designed to be staggered and used in pairs.

[0012] Preferably, the flow guide groove rotates in the same direction as the guide plate and the flow guide frame, and the flow guide groove is used in conjunction with the guide plate and the flow guide frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the cooperation of a guide plate and a flow guide frame, allows the brine inside the connecting pipe to rotate and form a vortex, thereby increasing the water flow speed and reducing the contact between the brine and the connecting pipe. Furthermore, with the assistance of a resistance-reducing plate, the friction between the connecting pipe and the brine can be further reduced, further increasing the flow rate. This reduces the loss of brine temperature during use, effectively improving the applicability of the pipe and solving the problem of slow brine flow and rapid temperature loss in existing pipes.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a chilled brine pipeline that reduces cold loss includes a connecting pipe 1. The surface of the connecting pipe 1 has mounting holes 2 for easy installation. An insulation board 3, made of a material with good thermal insulation properties, is installed on the surface of the connecting pipe 1. This insulation structure reduces heat loss from the inside of the connecting pipe 1. Several guide plates 4 are fixedly connected to the upper part of the inner cavity of the connecting pipe 1, arranged in a circular array around the center of the connecting pipe 1. The guide plates 4 have an inclined design, which allows the brine entering the connecting pipe 1 to form a spiral flow channel, thereby increasing... The increased flow rate of the brine reduces the contact time between the brine and the connecting pipe 1, thereby reducing the loss of brine temperature. A flow guide 5 is fixedly connected to the bottom of the guide plate 4. The flow guide 5 has a spiral structure design, and there are three flow guides 5, all of which work in conjunction with the guide plate 4. This allows the brine, after being guided by the guide plate 4, to be further guided continuously by the flow guides 5, enabling the brine to continuously rotate inside the connecting pipe 1, thus forming a vortex to increase the discharge of brine. Furthermore, this increased flow rate of the brine also reduces the residue of foreign matter inside the connecting pipe 1, effectively improving the applicability of the pipeline.

[0023] An auxiliary mechanism 6 is installed at the bottom of the inner cavity of the connecting pipe 1. The auxiliary mechanism 6 can support the flow guide 5, making the flow guide 5 more stable during use and preventing it from being unstable and affecting the flow of brine. Moreover, the auxiliary mechanism 6 can also calm the rotating brine, thereby reducing the rotation speed of the brine and preventing the brine from rotating too fast and affecting subsequent use. Several resistance-reducing plates 7 are fixedly connected inside the connecting pipe 1. The upper resistance-reducing plates 7 are staggered with the lower ones and used in pairs. Under this action, the water flow can be guided by the resistance-reducing plates 7, thereby reducing the friction between the water flow and the connecting pipe 1, further increasing the water flow rate and reducing the loss of brine temperature.

[0024] The auxiliary mechanism 6 includes a connecting plate 61 fixed to the inner wall of the connecting pipe 1. A positioning pipe 62 is fixedly connected to one side of the connecting plate 61. A guide groove 63 is provided on the inner wall of the positioning pipe 62. The guide groove 63 rotates in the same direction as the guide plate 4 and the guide frame 5. The guide groove 63 works in conjunction with the guide plate 4 and the guide frame 5. Under this action, the brine can be continuously accelerated through the cooperation of the guide groove 63, the guide plate 4 and the guide frame 5 to facilitate the discharge of brine. The brine outside the positioning pipe 62 will be guided by the connecting plate 61 to reduce the rotation amplitude. This reduces the rotation speed when the brine outside the positioning pipe 62 comes into contact with the brine inside the positioning pipe 62. The top of the positioning pipe 62 is fixedly connected to the bottom of the guide frame 5. Under this action, the guide frame 5 can be supported, making the guide frame 5 more stable during use and preventing it from shaking or shifting due to the influence of water flow rotation. This effectively improves the guiding effect of the guide frame 5 on the brine.

[0025] It is worth noting that the technical features such as the connecting pipe 1 and the insulation board 3 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, the pipe is connected to the brine chiller. When the brine chiller is in use, the brine enters the interior of the connecting pipe 1 from above. As the brine flows, it rotates under the guidance of the guide plate 4. With the continuous cooperation of the flow guide frame 5, the brine inside the connecting pipe 1 can form a vortex, thereby accelerating the flow rate of the brine and reducing the temperature loss of the brine. Furthermore, with the coordination of the number and position of the resistance reducing plates 7, the friction between the inner wall of the connecting pipe 1 and the brine can be further reduced, further accelerating the flow rate of the brine. When the brine flows to the lower part of the inner cavity of the connecting pipe 1, the positioning pipe 62 and the connecting plate 61 can guide part of the brine and reduce its rotation speed. With the cooperation of the flow guide groove 63, the flow rate of the brine inside the positioning pipe 62 is increased. Thus, when the brine is discharged from the pipe, the rotation speed of the brine on the outside is smaller, while that on the inside is larger, which facilitates the subsequent use of the brine.
