Description

Technical Field

[0001] The utility model relates to the technical field of homogenizers, in particular to a homogenizer with a cooling system. Background Art

[0002] A homogenizer is a device used to homogenize or emulsify materials. Since the amount of samples that need to be homogenized in the laboratory is small, the common homogenizer structure is relatively simple. Its main structure includes a homogenizing head, a power device for controlling the operation of the homogenizing head, and a fixing frame for fixing the homogenizing head and the power device.

[0003] The existing traditional small homogenizer does not include a cooling system. During use, the homogenizer head will produce a large temperature difference and quickly heat up due to the impact of the material and cavitation explosion, which will cause the homogenizer to overheat and need to be stopped for cooling and restarted. This has the disadvantage that the homogenizer cannot operate continuously, efficiently, and for a long time, reducing work efficiency. At the same time, high temperature will also cause the material to volatilize, resulting in deviations in the solid content of the experimental finished product, thereby affecting the experimental data. In addition, if the seal is not tight, it will also pollute the environment and cause certain harm to the human body. Utility Model Content

[0004] In view of this, the purpose of the utility model is to overcome the problems existing in the prior art and provide a homogenizer with a cooling system. The homogenizer is provided with a cavity interlayer in the hopper and a spiral guide vane in the cavity interlayer. The spiral guide vane exchanges heat with the inner hopper body to cool down the temperature of the inner hopper body, thereby achieving simultaneous homogenization and cooling work, thereby improving the working efficiency of the homogenizer.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

By arranging the spiral guide vane 5 in the cavity interlayer 4, the cooling water of the chiller 8 passes through the water inlet pipe 6 and the water inlet 9 in turn, along the spiral guide vane 5, and exchanges heat with the inner bucket body 2, so that the inner bucket body 2 can be cooled down and the homogenizer can continue to operate; the cooling water then enters the chiller 8 through the water outlet 10 and the water outlet pipe 7 in turn, is condensed by the chiller 8, and then repeats the heat exchange along the spiral guide vane 5 to realize the condensed water circulation.

[0022] Furthermore, the spiral guide vane 5 is spirally wound around the outer wall of the inner bucket body 2, the inner side of the spiral guide vane 5 is in contact with the outer wall of the inner bucket body 2, and the outer side of the spiral guide vane 5 is in contact with the inner wall of the outer bucket body 3, and the spiral guide vane 5, the inner bucket body 2 and the outer bucket body 3 form a spiral liquid flow channel. Cooling water can flow in a spiral direction along the upper end surface of the spiral guide vane 5, contact various positions of the outer wall of the inner bucket body 2, and perform heat exchange with the inner bucket body 2, thereby realizing cooling of the inner bucket body that performs homogenization work.

[0023] Furthermore, the water inlet 9 is arranged at the lower end of the outer wall of the outer bucket 3 and communicated with the lower end of the spiral guide plate 5, and the water outlet 10 is arranged at the upper end of the outer wall of the outer bucket 3 and communicated with the upper end of the spiral guide plate 5. The water inlet 9 is arranged at the lower end of the outer wall of the outer bucket 3 and the water outlet 10 is arranged at the upper end of the outer wall of the outer bucket 3, which can prolong the time of cooling water in the cavity interlayer 4, so that the heat exchange between the cooling water and the inner bucket 2 is more sufficient, and the cooling effect is improved.

[0024] Furthermore, the cooling system further includes a first valve 11 and a second valve 12, wherein the first valve 11 is provided on the water inlet pipe 6 to control the cooling water to flow into the cavity interlayer 4 through the water inlet 9; the second valve 12 is provided on the water outlet pipe 7 to control the cooling water to flow out of the cavity interlayer 4 through the water outlet 10. In this embodiment, by providing the first valve 11 and the second valve 12 made of stainless steel, it is convenient to control the water flow rate and facilitate subsequent maintenance.

[0025] Furthermore, the chiller 8 includes an evaporator 13, a condenser 14, a compressor 15, a water pump 16, a water filling port 17 and a cooling water tank 18.

The evaporator 13 is arranged in the cooling water tank 18 in the form of a coil; one end of the water inlet pipe 6 is connected to the water inlet 9, and the other end of the water inlet pipe 6 is connected to the output end of the water pump 16; one end of the water outlet pipe 7 is connected to the water outlet 10, and the other end of the water outlet pipe 7 is connected to the input end of the cooling water tank 18, and the water filling port 17 is connected to the cooling water tank 18.

After cooling, the cooling water enters the cavity interlayer 4 again through the output end of the water pump 16, the water inlet pipe 6 and the water inlet 9, thereby completing the cooling water cycle. When the water in the cooling water tank 18 is consumed and lacks water or the water level is too low, pure water is added to the cooling water tank 18 through the water replenishment port 17; adding pure water can prevent the pipes, water inlet pipe 6, water outlet pipe 7 and cavity interlayer 4 in the chiller 8 from scaling. The evaporator 13 is arranged in the cooling water tank 18 in the form of a coil, which is used to refrigerate the water in the cooling water tank 18 so that the cooling water that absorbs the heat of the cavity interlayer 4 can be cooled down. In this embodiment, the cooling water temperature can be set within 16-30°C, ±3°C through the control panel of the chiller 8, and the chiller 8 is used to cool the cooling water to achieve cooling water recycling. In this embodiment, the working pressure of the water pump 16 is 0.1-0.3MPa, and the water flow rate is 50-200L / min.

In practical applications, the material of the inner bucket body 2, the outer bucket body 3 and the spiral guide vane 5 is selected according to the characteristics of the material.

[0027] Further, the water inlet pipe 6 and the water outlet pipe 7 are both made of transparent PU pipe or PVC pipe.

Start the homogenizer host 1, and the inner bucket 2 performs homogenization; 6.
