Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a cooling structure for the housing of an electric actuator used for liquid level control in a crystallizer. Background Technology

[0002] Electric actuators, also known as electric cylinders, are high-precision transmission devices that use electrical energy to drive linear motion. Compared with traditional hydraulic drives, they have lower noise levels and more stable operating accuracy. They also have advantages such as fast response, excellent accuracy, and repeatability. When electric cylinders are used for crystallizer level control, the outer shell of the electric cylinder needs to be cooled to prevent the temperature inside the crystallizer from affecting the electric cylinder.

[0003] A search revealed a Chinese patent (application number "202311726643.X") disclosing "an external high-efficiency cooling circulation structure for a high-load-bearing electric cylinder." This cooling circulation structure includes an electric cylinder body, an oil cooling device, an oil tank, and a water tank. The electric cylinder body has an internal cooling channel; the oil cooling device is connected to the cooling channel within the electric cylinder body via a delivery pipe; the oil tank is connected to the oil cooling device and the cooling channel via a delivery pipe; and the water tank is connected to the oil cooling device via a delivery pipe. However, this cooling circulation structure does not provide heat insulation for the servo motor of the electric actuator during use, making the servo motor prone to overheating and reducing its operating efficiency. Utility Model Content

[0004] This invention provides a cooling structure for the housing of an electric actuator cylinder used for liquid level control in a crystallizer. It solves the problem proposed in the prior art that the cooling circulation structure does not insulate the servo motor of the electric actuator cylinder, which easily leads to overheating of the servo motor and reduced operating efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling structure for the outer shell of an electric actuator cylinder used for liquid level control in a crystallizer includes a cooling mechanism disposed on the outer wall of the electric actuator cylinder body. The cooling mechanism includes a cooling cylinder fixed to the outer wall of the electric actuator cylinder body, a spiral guide vane fixed to the inner wall of the cooling cylinder, and a spiral air guide groove formed on the outer wall of the cooling cylinder. A heat dissipation assembly is provided outside the cooling cylinder. The heat dissipation assembly includes a mounting cylinder bolted to the outer wall of the cooling cylinder and several heat dissipation fins respectively welded to the outer wall of the mounting cylinder. Several heat-resistant cooling fans are provided at one end of the mounting cylinder. A guide assembly is provided at one end of the mounting cylinder. The guide assembly includes a guide cover and a guide fan fixed to the outer wall of one end of the mounting cylinder. A heat insulation cover is bolted to the outer wall of the servo motor end of the electric actuator cylinder body.

[0006] Preferably, the spiral guide vane abuts against the outer wall of the electric actuator cylinder body via a sealing strip, an inlet pipe is fixedly provided on one inner wall of the cooling cylinder, and an outlet pipe is fixedly provided on the inner wall of the end of the cooling cylinder away from the inlet pipe, and the spiral air guide groove is located between the inlet pipe and the outlet pipe.

[0007] Preferably, the inlet pipe and the outlet pipe are respectively inserted through and connected to the outer wall of the mounting cylinder. A connecting pipe is fixed on the inner wall of the mounting cylinder near the inlet pipe, and an air outlet is opened on the outer wall of the mounting cylinder near the outlet pipe. The connecting pipe is connected to the spiral air guide groove.

[0008] The above scheme uses a cooling cylinder and an installation cylinder to form a complete sleeve. The inlet pipe and outlet pipe are connected to the coolant storage tank through metal hoses. A circulation pump is used to transport the coolant. The coolant enters the spiral guide vanes inside the cooling cylinder through the inlet pipe. The coolant flows spirally along the spiral guide vanes, increasing the coolant flow time and allowing the coolant to fully exchange heat with the heat on the electric actuator cylinder body.

[0009] Preferably, a mounting ring is bolted to the outer wall of the end of the mounting cylinder away from the liquid inlet pipe, and several heat-resistant cooling fans are bolted to the outer wall of one side of the mounting ring.

[0010] Preferably, an air guide ring is fixed on the outer wall of one end of the mounting cylinder, and air outlets are evenly distributed on the outer wall of the air guide ring, with the air outlets located inside the air guide ring.

[0011] Preferably, a mounting block is welded to one side of the outer wall of the guide cover, and the guide fan is bolted to the outer wall of the mounting block.

[0012] Preferably, an air inlet pipe is fixedly provided on one inner wall of the heat insulation cover, and an air outlet pipe is fixedly provided on one inner wall of the heat insulation cover. A conveying pipe is fixedly provided on the outer wall of one end of the air outlet pipe, and one end of the conveying pipe is fixedly provided on the outer wall of one end of the connecting pipe.

[0013] The above scheme connects the intake pipe to the compressed gas source (such as an air compressor) via a metal flexible hose. Compressed air enters the heat insulation cover along the intake pipe, transferring the heat generated by the servo motor of the electric actuator to the delivery pipe. The delivery pipe then transports the hot air to the spiral air guide groove. The hot air flows along the spiral air guide groove, where the coolant exchanges heat with the hot air. Simultaneously, the hot air exchanges heat with the mounting cylinder and multiple sets of heat dissipation fins. The cooled air is discharged through the air guide ring, and multiple sets of heat-resistant cooling fans operate to deliver cold air from one side of the mounting ring to the heat dissipation fins. The cold air transfers the heat from the heat dissipation fins to the guide cover, and then the guide fan delivers the hot air to the outside.

[0014] The beneficial effects of this utility model are as follows: 1. The coolant enters the spiral guide vanes inside the cooling cylinder through the inlet pipe. The coolant flows spirally along the spiral guide vanes, increasing the coolant flow time and allowing the coolant to fully exchange heat with the heat on the electric actuator cylinder body.

[0015] 2. The heat generated by the servo motor of the electric actuator cylinder body is transported through the spiral air guide groove. The coolant exchanges heat with the hot air in the spiral air guide groove. At the same time, the hot air exchanges heat with the mounting cylinder and multiple sets of heat dissipation fins. The cooled air is discharged through the air guide ring. Multiple sets of heat-resistant cooling fans operate to transport the cold air on one side of the mounting ring to the heat dissipation fins. The cold air transfers the heat on the heat dissipation fins to the guide cover. Then, the guide fan transports the hot air to the outside.

[0016] In summary, this invention can insulate the servo motor of the electric actuator and exchange the heat generated by the servo motor during operation. Subsequently, the cooled gas is used to cool the cylinder body of the electric actuator, thereby improving the operating efficiency of the servo motor and the electric actuator.

The inlet pipe and the outlet pipe are respectively connected to a coolant storage tank through metal hoses, and the coolant is transported by a circulating pump (not shown in the figure, prior art).

[0025] like Figure 3-4 As shown, a heat dissipation assembly 3 is provided on the outside of the cooling cylinder 201. The heat dissipation assembly 3 includes a mounting cylinder 301 that is bolted to the outer wall of the cooling cylinder 201 and several heat dissipation fins 302 that are respectively welded to the outer wall of the mounting cylinder 301. The liquid inlet pipe 203 and the liquid outlet pipe 204 pass through and are inserted into the outer wall of the mounting cylinder 301. A connecting pipe 303 is fixed on the inner wall of the end of the mounting cylinder 301 near the liquid inlet pipe 203. An air outlet 304 is opened on the outer wall of the end of the mounting cylinder 301 near the liquid outlet pipe 204. The connecting pipe 303 is connected to the spiral air guide groove 205.

[0026] Example 2: A cooling structure for the housing of an electrically driven actuator cylinder used for crystallizer level control, such as... Figure 1As shown, the device includes a heat-resistant cooling fan 5. A mounting ring 4 is bolted to the outer wall of the mounting cylinder 301 at one end away from the liquid inlet pipe 203. Several heat-resistant cooling fans 5 are bolted to the outer wall of the mounting ring 4 on one side. A guide ring 6 is fixed on the outer wall of one end of the mounting cylinder 301. The guide ring 6 has equidistantly distributed air outlets on its outer wall. The air outlet 304 is located inside the guide ring 6.

[0027] like Figure 5 As shown, the guide assembly 7 includes a guide cover 701 and a guide fan 703 fixed to the outer wall of one end of the mounting cylinder 301. A mounting block 702 is welded to one side of the outer wall of the guide cover 701, and the guide fan 703 is bolted to one side of the outer wall of the mounting block 702.

[0028] Example 3: A cooling structure for the housing of an electrically driven actuator cylinder used for crystallizer level control, such as... Figure 1 As shown, a heat shield 8 is bolted to the outer wall of the servo motor end of the electric actuator cylinder body 1. The heat shield 8 covers the servo motor on the electric actuator cylinder body 1 to prevent the servo motor from being affected by the radiant heat of the crystallizer. An air inlet pipe 9 is fixed on one inner wall of the heat shield 8. The air inlet pipe 9 is connected to a compressed gas source (such as an air compressor) through a metal hose.

[0029] Working principle: Coolant enters the spiral guide vane 302 inside the cooling cylinder 301 through the inlet pipe 203. The coolant flows spirally along the spiral guide vane 302, increasing the coolant flow time and allowing the coolant to fully exchange heat with the cylinder body of the electric actuator 1. Compressed air enters the heat insulation cover 8 through the air inlet pipe 9, transferring the heat generated by the servo motor of the electric actuator 1 to the delivery pipe 10. The delivery pipe 10 then delivers the hot air to the spiral air guide groove 205. The hot air flows along the spiral air guide groove 205... 5. The coolant exchanges heat with the hot air in the spiral air guide groove 205. At the same time, the hot air exchanges heat with the mounting cylinder 301 and multiple sets of heat dissipation fins 302. The cooled air is discharged through the air guide ring 6. Multiple sets of heat-resistant cooling fans 5 operate to transport the cold air on one side of the mounting ring 4 to the heat dissipation fins 302. The cold air transfers the heat on the heat dissipation fins 302 to the guide cover 701. Then, the guide fan 703 transports the hot air to the outside, avoiding the hot air from blowing directly to the gearbox of the electric actuator cylinder body 1, which would cause the temperature inside the gearbox to rise.
