Description

Technical Field

[0001] This utility model relates to the field of dairy product manufacturing technology, specifically a precision control double-layer three-tube heating device for a goat milk dairy product CIP cleaning line. Background Technology

[0002] Dairy product manufacturing refers to the production of various foods using cow's milk or sheep's milk and their processed products as the main raw materials, with or without the addition of appropriate amounts of vitamins, minerals and other auxiliary materials. A dairy product manufacturing CIP cleaning line is a system used for equipment cleaning during the dairy product production process.

[0003] The main function of a CIP cleaning line is to remove dirt and residues from inside the equipment through chemical and mechanical action without disassembling the equipment, ensuring the hygiene and cleanliness of the production equipment. The double-layer three-tube heating equipment of the CIP cleaning line is a high-efficiency, energy-saving, and hygienic heating device specifically designed for dairy processing. It is mainly used for heating the medium (water, acid, alkali, etc.) in the CIP cleaning process or heating the liquid material in the production process. Currently, double-layer three-tube heating devices cannot filter impurities in the circulating liquid heating medium during use. When these impurities enter the device, they can easily cause pipe blockage and are difficult to clean. At the same time, they cannot monitor the heating temperature, resulting in uneven and incomplete heating, and they cannot flexibly adjust the liquid flow rate according to the temperature. In order to solve the above technical problems, we have designed a precision-controlled double-layer three-tube heating device for goat milk dairy product CIP cleaning lines. Utility Model Content

[0004] The purpose of this invention is to provide a precision-controlled double-layer three-tube heating device for CIP cleaning lines of goat milk dairy products. It has a pre-filtration function to prevent impurities in the heating medium from entering the tubes, avoiding blockage and reducing cleaning difficulty. It can adjust the flow rate according to the heating temperature to ensure uniform heating. It solves the problems of not being able to filter impurities in the heating medium, which easily causes pipe blockage, increases cleaning difficulty, and not being able to adjust the flow rate according to the heating temperature, resulting in uneven and incomplete heating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision-controlled double-layer three-tube heating device for a CIP cleaning line of goat milk dairy products, comprising an outer tube, with outer end plates welded to the top and bottom of the outer tube, a filter mechanism fixedly installed on the bottom of the outer surface of the outer tube, the filter mechanism comprising a fixed shell, a filter screen plate fixedly connected to the inner cavity of the fixed shell, a middle tube and an inner tube respectively welded between the two outer end plates, a spiral heat-conducting pipe welded to the inner cavity of the inner tube, an installation shell fixedly connected to the bottom of the outer end plates, and a temperature sensor installed through the left side of the installation shell.

[0006] Preferably, the bottom of the mounting housing is connected to a drain pipe, and a first electric valve is sleeved on the surface of the drain pipe.

[0007] Preferably, the top of the outer end plate is welded to a liquid injection tube, and a pressure sensor is installed through the bottom of the right side of the outer tube.

[0008] Preferably, the top right side of the intermediate tube is connected to an outlet tube, and the right side of the outlet tube penetrates the outer tube and is fitted with a second electric valve.

[0009] Preferably, a slag discharge opening is provided at the bottom of the left side of the fixed shell, and a cover plate is installed on the outside of the slag discharge opening by bolts.

[0010] Preferably, a gas filling pipe is welded to the left side of the top of the outer end plate, and a third electric valve is sleeved on the surface of the gas filling pipe.

[0011] Preferably, the inner wall of the outer tube is coated with a mercury coating, the top of the fixed shell is fixedly connected to an installation water pipe, and the bottom of the fixed shell is connected to a connecting water pipe that passes through the outer tube and is fixedly connected to the middle tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The heating medium flows into the fixed shell, and the filter screen filters the impurities in the heating medium. The filtered heating medium enters the bottom of the intermediate tube and finally flows out from the outlet pipe. This can filter the impurities in the heating medium to avoid clogging the pipeline and reduce the difficulty of cleaning.

[0014] The heated medium flows out from the mounting shell. The temperature sensor monitors the temperature of the cleaning medium. When the temperature does not reach the preset temperature, the opening of the first electric valve is reduced to decrease the flow rate and extend the time the cleaning medium stays in the inner tube for more thorough heating. This allows for monitoring of the heating temperature and flexible adjustment of the medium flow rate to ensure more uniform heating. Attached Figure Description

[0019] Please see Figures 1-3 A precision-controlled double-layer three-tube heating device for a goat milk dairy product CIP cleaning line includes an outer tube 1. By setting the outer tube 1, heat-insulating gas can be injected into the tube to prevent heat loss. The top and bottom of the outer tube 1 are welded with outer end plates 2. A filter mechanism 7 is fixedly installed at the bottom of the outer surface of the outer tube 1. The filter mechanism 7 includes a fixed shell 18. A filter screen plate 17 is fixedly connected to the inner cavity of the fixed shell 18. An intermediate tube 19 and an inner tube 20 are welded between the two outer end plates 2 respectively. A spiral heat-conducting tube 21 is welded and connected to the inner cavity of the inner tube 20. By setting the spiral heat-conducting tube 21, the heating medium can flow through from the inside to increase the heating area with the cleaning medium and make the heating more uniform and thorough. The bottom of the outer end plate 2 is fixedly connected to an installation shell 11. A temperature sensor 8 is installed through the left side of the installation shell 11.

[0020] Please see Figure 1 The bottom of the mounting housing 11 is connected to a drain pipe 10, and a first electric valve 9 is sleeved on the surface of the drain pipe 10. By setting the first electric valve 9, the flow rate of the medium can be flexibly adjusted.

[0021] Please see Figure 1 The top of the outer end plate 2 is welded to the injection pipe 3, and the bottom right side of the outer tube 1 is fitted with a pressure sensor 12. By setting the pressure sensor 12, the pressure of the insulation gas in the outer tube 1 can be monitored in real time. When the pressure drops, the information is transmitted to the PLC controller to control the third electric valve 4 to open and inject insulation gas into the tube 1.

[0022] Please see Figure 2 The top right side of the intermediate tube 19 is connected to the outlet tube 13. The right side of the outlet tube 13 passes through the outer tube 1 and is fitted with a second electric valve 14. By setting the second electric valve 14, the flow rate of the heating medium can be controlled by controlling the size of the valve core opening, so that the cleaning medium in the tube can be fully heated.

[0023] Please see Figure 2The bottom left side of the fixed shell 18 has a slag discharge opening 16. By setting the slag discharge opening 16, the filtered impurities can be cleaned inside the open cover plate 15. The outside of the slag discharge opening 16 is sealed with a cover plate 15 by bolts.

[0024] Please see Figure 2 A gas filling pipe 5 is welded to the left side of the top of the outer end plate 2. By setting the gas filling pipe 5, it can be connected to the external heat insulation gas injection pipe, so as to conveniently add heat insulation gas into the outer pipe 1. A third electric valve 4 is sleeved on the surface of the gas filling pipe 5.

[0025] Please see Figure 2 and Figure 3 The inner wall of the outer tube 1 is coated with a mercury coating 22. By setting the mercury coating 22, the path of heat radiation can be blocked, making the heat preservation effect more significant. The top of the fixed shell 18 is fixedly connected to the installation water pipe 6. By setting the installation water pipe 6, it can be connected to the external heating medium input pipe. The connecting water pipe at the bottom of the fixed shell 18 passes through the outer tube 1 and is fixedly connected to the middle tube 19.

[0026] In use, the input pipe of the cleaning medium is connected to the injection pipe 3, and then the output pipe is connected to the drain pipe 10. The input and output pipes of the heating medium are then connected to the installation water pipe 6 and the outlet pipe 13, respectively. The heating medium first flows into the fixed shell 18, and then the filter screen 17 filters the impurities in the heating medium. The filtered heating medium enters the bottom of the intermediate pipe 19, and the spiral heat conduction pipe 21 is also filled. Finally, it flows out from the outlet pipe 13. This can filter the impurities in the heating medium to avoid clogging the pipe and reduce the difficulty of cleaning. At this time, the cleaning medium flows into the inner tube 20 for heating. After heating, it flows out from the installation shell 11. The temperature sensor 8 monitors the temperature of the heated cleaning medium. The detected temperature value is transmitted to the PLC controller and displayed on the control screen. When the temperature does not reach the preset temperature, the opening of the first electric valve 9 is reduced to reduce the flow rate and extend the time of the cleaning medium in the inner tube 20 for more thorough heating. This allows for monitoring of the heating temperature and flexible adjustment of the medium flow rate to make the heating more uniform.

[0027] In summary, this CIP cleaning line for goat milk dairy products uses a precise control double-layer three-tube heating device. Through the coordinated use of the outer tube 1, outer end plate 2, third electric valve 4, filter mechanism 7, temperature sensor 8, liquid outlet tube 13, second electric valve 14, middle tube 19, and inner tube 20, it solves the problems of not being able to filter impurities in the heating medium, easily causing pipeline blockage, increasing cleaning difficulty, not being able to adjust the flow rate according to the heating temperature, and insufficient and uneven heating.
