Description

Technical Field

[0001] The utility model relates to the technical field of disc sand mills, in particular to an automatic temperature control device for an eccentric disc sand mill. Background Art

[0002] The eccentric disc sand mill is a device used for grinding. The delivery pump pumps the pre-diluted and stirred liquid-solid mixed raw materials into the cylinder. The main shaft drives the dispersion turbine to rotate at high speed and stirs the grinding medium in the cylinder to produce swirl and radial and axial movement, thereby forcibly grinding and dispersing the product to achieve the specified fineness. At the same time, the electric contact pressure gauge and electric contact temperature gauge automatically control its working pressure and working temperature to ensure the safe operation of the whole machine.

[0003] The existing Chinese patent CN217856510U disclosed a temperature control structure and a sand mill on November 22, 2022. The temperature control structure and the sand mill include a grinding cylinder shell and a main frame. A water outlet pipe is fixedly connected to the upper right side of the grinding cylinder shell, and a pipe is arranged on the upper left side of the water outlet pipe. An auxiliary heat dissipation component is arranged on the outside of the pipe, and the auxiliary heat dissipation component includes a fixed frame, heat dissipation fins and a heat dissipation cover. The outer wall of the fixed frame is fixedly connected to the heat dissipation fins, and a heat dissipation cover is arranged on the outside of the heat dissipation fins. A fan is arranged at the lower left side of the heat dissipation cover, and the main frame is arranged below the fan. However, when the above-mentioned device is temperature controlled as a whole, heat is dissipated through the heat dissipation fins, the heat dissipation cover and the fan. During the heat dissipation, the temperature of the heat dissipation fins cannot be effectively and quickly dissipated, and the temperature emitted by the heat dissipation fins is still easily transferred to the grinding cylinder shell, which makes the heat dissipation not very efficient.

[0004] In order to solve the above problems, the present application proposes an automatic temperature control device for an eccentric disc sand mill. Utility Model Content

[0027] The temperature sensors 101 symmetrically installed on both sides receive the temperature of the eccentric disc sand mill body 1. When the temperature inside the eccentric disc sand mill body 1 rises, the temperature sensor 101 is electrically connected to the thermostat 6 through a wire, and the thermostat 6 is electrically connected to the controller 4 through a wire. Thus, the temperature sensor 101 sends a signal to the controller 4 through the thermostat 6. The controller 4 controls the first liquid pump 702 of the circulating cooling mechanism 7 to supply liquid for cooling. The hollow circulating coiled heat dissipating fin plate 510 of the secondary cooling mechanism 5 controls the circulating cooling mechanism 7 for cooling, thereby realizing the overall secondary cooling liquid supply temperature control.

[0028] like Figure 1 and Figure 2 As shown, the outer end of the first liquid pump 702 is located on the first cooling water tank 3 and is provided with a delivery water pipe 703. The input pipe 704 is connected to the cooling wrapping sleeve 8. The first liquid pump 702 can extract the coolant in the first cooling water tank 3 through the delivery water pipe 703 for delivery. The coolant is delivered to the disc circulation pipe 701 through the first liquid pump 702, and then passes through the input pipe 704 at the right end of the disc circulation pipe 701, and then is delivered to the cooling wrapping sleeve 8 through the input pipe 704. The cooling wrapping sleeve 8 is wrapped on the outer side of the eccentric disc sand mill body 1, so that the delivery of the cooling liquid is realized. The cooling wrapping sleeve 8 is connected to the first cooling water tank 3, thereby realizing the circulation delivery of the cooling liquid.

[0029] like Figure 1 and Figure 3As shown, the cooling wrapping sleeve 8 includes a hollow open sleeve plate 804, which is hollow inside so that the coolant can be stored for wrapping and absorbing heat and cooling. The front end opening of the hollow open sleeve plate 804 is equipped with a locking screw 802, so as to facilitate the fixation of the hollow open sleeve plate 804. The lower end of the hollow open sleeve plate 804 is located on the first cooling water tank 3 and is screwed to the water tank connecting pipe 803. The coolant inside the hollow open sleeve plate 804 can be discharged into the first cooling water tank 3, so that it can be circulated for cooling. The outer side of the water tank connecting pipe 803 is located A supporting column 801 is fixedly connected to the hollow open sleeve 804, so that it can be supported and placed to maintain the placement stability of the water tank connecting pipe 803. An internal copper plate 805 is fixedly connected to the inner side of the hollow open sleeve 804. The internal copper plate 805 can efficiently absorb the internal temperature of the eccentric disc sand mill body 1, and then the temperature can be efficiently diffused into the coolant inside the hollow open sleeve 804, which is more efficient in heat dissipation. The hollow open sleeve 804 is sleeved on the peripheral side of the eccentric disc sand mill body 1 for easy installation and use.

[0030] Figure 1 , Figure 2 and Figure 4As shown, the secondary cooling mechanism 5 includes a heat insulation panel 520, and three groups of heat dissipation fans 550 are fixed to the inner side of the upper end of the heat insulation panel 520 by screws, and each group is provided with two, so that the three groups of heat dissipation fans 550 can dissipate heat to the outside, and the lower end inner side of the heat insulation panel 520 is fixedly connected to a connecting end plate 540, and the connecting end plate 540 is fixedly connected to the eccentric disc sand mill body 1, so that the heat insulation panel 520 can be placed on the outside of the eccentric disc sand mill body 1, which can isolate the temperature emitted by the hollow circulating coiled heat dissipation fin plate 510 and prevent the temperature from diffusing to the eccentric disc sand mill body 1. The heat dissipation fan 550 can blow air to dissipate heat to the eight outer hollow circulating coiled heat dissipation fin plates 510, and the water inlet ends of the eight hollow circulating coiled heat dissipation fin plates 510 are all connected to the collecting and shunt pipe 570, and the transported coolant can be diverted and transported to each hollow circulating coiled heat dissipation fin plate 510. The cooling is carried out in the cooling unit, and the water outlet ends of the eight hollow circulating coiled heat dissipating fins 510 are all connected to the collecting and draining pipe 530. The coolant in the eight hollow circulating coiled heat dissipating fins 510 can be collected and discharged. The lower end of the collecting and draining pipe 530 is connected to the secondary cooling water tank 2, so that it can be discharged into the secondary cooling water tank 2 for collection. The outer end of the collecting and shunt pipe 570 is screwed to a second liquid pump 560. The second liquid pump 560 is connected to the secondary cooling water tank 2 through a pipeline. In this way, the coolant in the secondary cooling water tank 2 can be circulated and transported through the second liquid pump 560. The hollow circulating coiled heat dissipating fins 510 are coiled and fixedly connected to the disc circulation pipe 701, so that the heat absorbed by the hollow circulating coiled heat dissipating fins 510 can be dissipated, which effectively ensures the heat absorption state of the hollow circulating coiled heat dissipating fins 510 and effectively cools down, making the automatic temperature control cooling more efficient.
