Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, in particular to a dripping liquid temperature control component for a peristaltic pump. Background Art

[0002] A peristaltic pump is a liquid delivery device that can control the flow rate. The peristaltic pump generates the power for fluid delivery by compressing the hose, so that the fluid in the hose is pushed to the outlet of the pipe, forming a continuous flow. There is no direct contact between the fluid and the pump structure of the peristaltic pump, so pollution-free delivery can be achieved, which is suitable for occasions with high requirements for fluid purity. Since the peristaltic pump controls the delivery volume of the fluid by rotating the roller, it can achieve more accurate flow control and metering, which is suitable for experiments and processes that require precise control of the liquid flow rate.

[0003] However, in the traditional method, it is relatively inconvenient to use a peristaltic pump to control the temperature of the dripping liquid, and large temperature fluctuations are prone to occur. Especially in a low-temperature environment, the temperature of the dripping liquid is difficult to maintain stable, affecting the accuracy and stability of the experiment.

[0004] In view of this, the utility model provides a dripping liquid temperature control component for a peristaltic pump. Utility Model Content

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] Example: Figure 1-3 As shown, the device includes a temperature control structure 1. Considering that in traditional methods, it is relatively inconvenient for a peristaltic pump to control the temperature of the dripping liquid, and large temperature fluctuations are prone to occur, especially in a low-temperature environment. The temperature of the dripping liquid is difficult to maintain stable, affecting the accuracy and stability of the experiment. Therefore, the specific structure is as follows: the temperature control structure 1 includes a delivery pipe 10 and a guide pipe 11. A sleeve 101 is provided on the axial side of the delivery pipe 10. A cavity is formed between the delivery pipe 10 and the sleeve 101. A water inlet 1011 is installed at the bottom of the outer wall of the sleeve 101, and a water outlet 1012 is installed at the top. The water inlet 1011 and the water outlet 1012 are both connected to the cavity, and the water inlet 1011 and the water outlet 1012 are commonly connected to a circulating water device, and the end of the guide pipe 11 is movably connected to the end of the delivery pipe 10.

[0022] The improvement of this embodiment is that:

[0023] By forming a double-layer glass tube structure through the delivery tube 10 and the sleeve 101 and combining it with an external circulating water device, the temperature of the added monomer can be accurately controlled, avoiding the influence of temperature fluctuations on the experimental results. At the same time, the design of the double-layer glass tube structure effectively reduces heat loss and improves the accuracy of temperature control.

[0024] Taking into account the need to control the liquid flow rate, the guide tube 11 includes a mounting tube 111 and a connecting tube 112. A support plate 1123 is installed inside the connecting tube 112. A flow hole 1124 is provided on the surface of the support plate 1123. A support column 1125 is fixedly connected to the surface of the support plate 1123. A cover plate 1126 is rotatably connected to the side of the support column 1125 axis. The size of the flow hole 1124 can be controlled by manually adjusting the area of ​​the flow hole 1124 covered by the cover plate 1126. The larger the covered area, the greater the liquid flow rate. Conversely, the smaller the covered area, the smaller the liquid flow rate, thereby controlling the liquid flow rate.

[0025] In order to facilitate the cleaning of the guide tube 11, an internal thread is provided on the inner wall below the mounting tube 111, a mounting cylinder 1122 is fixedly connected to the upper surface of the connecting tube 112, and an external thread is provided on the outer wall of the mounting cylinder 1122, wherein: the internal thread and the external thread cooperate with each other, and the connecting tube 112 and the mounting tube 111 can be controlled to be installed or disassembled by rotating the connecting tube 112, thereby facilitating the cleaning of the interior.

[0026] In order to prevent the circulating water and the dripping liquid from mixing and flowing into the guide tube 11, a rubber sealing sleeve 1010 is provided on the outer wall of the delivery pipe 10, one end of the rubber sealing sleeve 1010 is connected to the end of the mounting tube 111, and the other end is provided at the end of the sleeve 101. The rubber sealing sleeve 1010 is used to seal the mounting tube 111 and the sleeve 101.

[0027] Considering that the dropping liquid needs to enter the interior of the delivery tube 10 for transportation, a sealing plug 102 is movably connected to the end of the delivery tube 10, a delivery hole 1021 is opened on the surface of the sealing plug 102, and a compression hose is installed at the end of the delivery hole 1021. The dropping liquid passes through the compression hose and then passes through the peristaltic pump and then enters the delivery tube 10 through the compression hose.

[0028] In order to control the liquid flow rate, a dripping port 1121 is installed at the end of the connecting pipe 112, and the dripping port 1121 is designed to be thinner.

[0029] Secondly, the covering plate 1126 is set to a sickle-shaped structure, which is convenient for partially covering the flow hole 1124 and controlling the flow rate of the liquid.

[0030] In summary, the working principle of this solution is as follows:

[0031] A compression hose is installed at the end of the delivery hole 1021. The peristaltic pump generates power for fluid delivery by compressing the hose, so that the fluid in the hose is pushed into the interior of the delivery tube 10 to form a continuous flow. There is no direct contact between the fluid of the peristaltic pump and the pump structure itself, so pollution-free delivery can be achieved; the water inlet 1011 and the water outlet 1012 are jointly connected to a temperature-controlled water circulation device. The delivery tube 10 is relatively thin, and the inside is used to pass the monomer added by the peristaltic pump. The sleeve 101 is relatively thick, and the cavity formed between the sleeve 101 and the delivery tube 10 is used to pass circulating water. The temperature of the added monomer is precisely controlled by the temperature conduction principle, and the temperature control is The circulating water in the water circulation device enters the cavity from the water inlet 1011 and flows out of the cavity from the water outlet 1012. By controlling the temperature of the circulating water inside the cavity, the temperature of the dripping monomer in the delivery pipe 10 is indirectly affected, thereby achieving precise control of the temperature of the dripping monomer; thereafter, the dripping liquid enters the reaction container through the guide tube 11, wherein 111 and 112 can be installed and disassembled by means of internal and external threads, so that the user can manually adjust the size of the area of ​​the flow hole 1124 covered by the cover plate 1126, so as to control the size of the flow hole 1124, thereby controlling the size of the liquid flow, and also facilitating the cleaning of the guide tube 11.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
