Description

Technical Field

[0001] The present application relates to the technical field of sand mills, and in particular to a sand mill with a cooling function. Background Art

[0002] Horizontal sand mill is a kind of grinding equipment which is widely used in coating industry. This kind of grinding machine can work continuously without interruption and has the characteristics of high speed and high efficiency. It is widely used in non-metallic mining industries such as coatings, dyes, paints, inks, medicines, magnetic powders, ferrites, photographic films, pesticides, papermaking and cosmetics.

[0003] A sand mill anti-blocking mechanism mentioned in an existing Chinese public patent (authorization announcement number: CN219849913U) can use a purely physical structure to automatically slow down the feeding speed in the feed port when materials accumulate above the filter plate, coordinate the feeding speed and processing speed of the sand mill, and effectively reduce the possibility of the sand mill being blocked.

The coolant in the water tank gradually becomes hot, which reduces the cooling effect of the grinding barrel, thus affecting the subsequent processing. Utility Model Content

[0033] The following is combined with Figures 1 to 5 This application is described in further detail.

[0034] The embodiment of the present application discloses a sand grinder with a cooling function.

[0035] Reference Figure 1 , Figure 2 and Figure 4 A sand mill with a cooling function comprises a base 1, a vertical plate 2 is fixedly connected to the top of the base 1, a control panel 8 is fixedly connected to one side of the vertical plate 2, a rotating motor 3 is fixedly connected to one side of the vertical plate 2, a cylinder 4 is fixedly connected to one side of the vertical plate 2 below the rotating motor 3, a heat dissipation cylinder 6 is fixedly connected to the outer surface of the cylinder 4, a temperature sensor 1 is arranged inside the heat dissipation cylinder 6, the temperature sensor 1 is electrically connected to the control panel 8, a discharge port 5 is fixedly connected to one side of the cylinder 4, a fixing seat 7 is fixedly connected to the bottom of the cylinder 4, the bottom of the fixing seat 7 is fixedly connected to the base 1, a control panel 8 is fixedly connected to one side of the vertical plate 2, the control panel 8 is electrically connected to the rotating motor 3, a temperature control mechanism is arranged on one side of the base 1, and fixing mechanisms are arranged on both sides of the top of the base 1.

[0036] When grinding the material, first drive the rotating motor 3 through the control panel 8 to start grinding the material inside the barrel 4, and the ground material is discharged through the discharge port 5. During the grinding process, the temperature inside the barrel 4 is sensed by the temperature sensor 1. At this time, the temperature sensor 1 sends a signal to the control panel 8, and the temperature control mechanism is started through a preset program to dissipate heat inside the barrel 4, thereby increasing the service life of the barrel 4. When the barrel 4 is working, the barrel 4 is fixed by a fixing mechanism to reduce the risk of the sand mill body shaking during operation.

[0037] Reference Figure 2 and Figure 3 The temperature control mechanism includes a water tank 9 fixedly connected to one side of the base 1, and a temperature sensor 19 is fixedly connected to the inner wall of the water tank 9, and the temperature sensor 19 is electrically connected to the control panel 8. A water inlet 10 is fixedly connected to one side of the water tank 9, and the water inlet 10 is connected to the water tank 9. A water pump 11 is fixedly connected to the top of the water tank 9, and the water pump 11 is electrically connected to the control panel 8. The water inlet end of the water pump 11 passes through the water tank 9 and is fixedly connected to a water inlet pipe 12, and the water inlet pipe 12 is connected to the water pump 11. A water outlet pipe 13 is fixedly connected to the top of the water pump 11, and the water outlet pipe 13 is connected to the water pump 11. A cavity is opened inside the heat dissipation tube 6, and a heat absorption tube 14 is arranged inside the cavity. The end of the water outlet pipe 13 away from the water pump 11 passes through the heat dissipation tube 6 and is connected to the heat absorption tube 14. A refrigeration component is arranged inside the water tank 9.

[0038] One end of the heat absorption pipe 14 away from the water outlet pipe 13 is fixedly connected to the circulation pipe 15 , and one end of the circulation pipe 15 away from the heat absorption pipe 14 penetrates the water tank 9 and extends to the inside of the water tank 9 .

[0039] In addition, the heat absorbing pipe 14 is provided in a spiral shape.

[0040] When the internal temperature of the cylinder 4 rises to the specified temperature, a signal is sent to the control panel 8 through the temperature sensor 1. After receiving the signal, the control panel 8 starts the water pump 11 to extract the coolant in the water tank 9. The extracted coolant enters the water outlet pipe 13 and is connected with the heat absorption pipe 14 through the water outlet pipe 13, so that the coolant enters the heat absorption pipe 14, and then takes away the heat generated when the cylinder 4 is working, reduces the temperature of the grinding cylinder, thereby improving the grinding performance of the material, preventing the material from agglomerating, and improving the grinding efficiency. After the coolant absorbs the heat, it is connected with the heat absorption pipe 14 through the circulation pipe 15, so that the coolant enters the water tank 9 through the circulation pipe 15, thereby continuously cooling the grinding cylinder. When the coolant absorbs heat, the heat absorption pipe 14 is set to a threaded shape, so that the contact area between the heat absorption pipe 14 and the cylinder 4 becomes larger, thereby improving the heat absorption performance of the heat absorption pipe 14.

[0041] Reference Figure 4The refrigeration component includes a heat absorbing tube 16 arranged inside the water tank 9. The top of the heat absorbing tube 16 is set to be open. A through hole 17 is opened on the top of the water tank 9. The through hole 17 matches the opening of the heat absorbing tube 16. The heat absorbing tube 16 is fixedly connected to the inner wall of the through hole 17.

[0042] Among them, the top of the water tank 9 is fixedly connected to a heat sink 20, the bottom of the heat sink 20 is set to an opening shape, the top of the water tank 9 is fixedly connected to a mounting seat 21, the top of the mounting seat 21 is fixedly connected to a fan 22, and a vent 23 is opened on one side of the heat sink 20, and the vent 23 is adapted to the blowing end of the fan 22.

[0043] When cooling the cylinder 4, the water after absorbing heat will gradually heat up the water inside the water tank 9. The material of the heat absorbing cylinder 16 is set to copper, which has good heat absorption performance, so that the temperature is absorbed into the inside of the heat absorbing cylinder 16. When the temperature rises to the specified temperature, the temperature sensor 19 sends a signal to the control panel 8. After the control panel 8 receives the signal, the fan 22 is started through a preset program. The blowing end of the fan 22 is adapted to the vent 23, so that the hot air inside the heat absorbing cylinder 16 is drawn out and discharged, thereby forming heat exchange with the external air, thereby increasing the heat exchange rate between the coolant and the external air, and taking away the temperature of the coolant through the flowing air, so that the coolant in the water tank 9 quickly dissipates heat, thereby facilitating the circulation and cooling of the cylinder 4.

[0044] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism includes a lifting plate 24 fixedly connected to both sides of the top of the base 1, a slide plate 25 is slidably connected between the lifting plates 24 on both sides, a lifting seat 26 is fixedly connected to the side of the lifting plates 24 close to each other, an electric push rod 27 is fixedly connected to the top of the lifting seat 26, the top of the electric push rod 27 is fixedly connected to the slide plate 25, and the electric push rod 27 is electrically connected to the control panel 8.

[0045] The bottom of the slide plate 25 is provided with an arc groove, which matches the shape of the heat dissipation tube 6.

[0046] When grinding materials, the electric push rod 27 is started through the control panel 8, and the electric push rod 27 drives the slide plate 25 to move downward until the slide plate 25 firmly contacts the heat sink 6, so that the slide plate 25 clamps the heat sink 6, thereby fixing the cylinder body 4, reducing the risk of the sand mill body shaking during operation. By matching the shape of the arc groove with the heat sink 6, the contact area between the slide plate 25 and the heat sink 6 is increased, thereby further improving the fixing effect.

[0047] Working principle: the rotating motor 3 is driven by the control panel 8 to start grinding the material inside the cylinder 4, and the ground material is discharged through the discharge port 5. During the grinding process, the temperature inside the cylinder 4 is sensed by the temperature sensor 1. At this time, the temperature sensor 1 sends a signal to the control panel 8. After receiving the signal, the control panel 8 starts the water pump 11 to extract the coolant in the water tank 9. The extracted coolant enters the water outlet pipe 13, and is connected with the heat absorption pipe 14 through the water outlet pipe 13, so that the coolant enters the heat absorption pipe 14, thereby taking away the heat generated by the cylinder 4 when working, and reducing the temperature of the grinding cylinder.

[0048] The blowing end of the fan 22 is adapted to the vent 23, so that the hot air inside the heat absorption tube 16 is drawn out and discharged, thereby forming heat exchange with the external air, thereby increasing the heat exchange rate, and taking away the temperature of the coolant through the flowing air. The electric push rod 27 is started through the control panel 8, and the electric push rod 27 drives the slide plate 25 to move downward until the slide plate 25 firmly contacts the heat dissipation tube 6, so that the slide plate 25 clamps the heat dissipation tube 6, thereby fixing the tube body 4, reducing the risk of shaking of the sand grinder during operation.
