[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0023] Example:

[0024] like Figure 1-Figure 3As shown, a slurry automatic pressure control device includes a bottom plate 1, the inner cavity of the bottom plate 1 is provided with a support mechanism 2, the top of the bottom plate 1 is fixedly connected with a pressure tank 3, the pressure tank 3 is respectively provided with a pressurizing pipe 4, a pressure gauge 5 and a pressure pipe 6, and the pressure pipe 6 is provided with a solenoid valve 7. The pressure tank is connected to the casting box of the placement mechanism (it can also be other corresponding structures), and the bottom of the placement mechanism 8 is provided with a photoelectric sensor 9. It should be noted that the nitrogen pressure in the pressure tank 3 should be controlled at 0.2Mpa, and the internal pressure of the pressure tank 3 can be maintained by connecting the pressurizing pipe 4 to an external compressor, and the compressed gas is selected according to demand, such as nitrogen. When using this device, the pressure tube 6 can be connected to the casting box in the casting equipment, and the photoelectric sensor 9 can be set up at the casting equipment through the placement mechanism 8. The distance of the slurry is measured by the photoelectric sensor 9. A small distance means there is material, and a large distance means there is no slurry. The photoelectric sensor 9 detects the obtained signal and transmits the signal to the external PLC. When there is no slurry, the external PLC controls the solenoid valve 7 to operate, and pressurizes the casting box through the pressure tank 3 to facilitate the discharge of the slurry.

[0025] In the specific implementation process, Figure 1 and Figure 2 As shown, the support mechanism 2 includes a support rod 201, the outer side of the support rod 201 is threadedly connected to the inner cavity of the bottom plate 1, the bottom of the support rod 201 is rotatably matched with a support plate 202, the top of the support rod 201 is fixedly connected with a rotating block 203, and the number of the support rods 201 is set to four;

[0026] The bottom of the support plate 202 is fixedly connected with a rubber pad 10 , and the outer side of the rubber pad 10 is provided with anti-slip grooves.

[0027] It should be noted that: moving wheels are provided at the bottom of the base plate 1. When moving the pressure tank 3, the support rod 201 can be rotated so that the support rod 201 drives the support plate 202 to move upward, thereby making the support plate 202 away from the ground and supported by the moving wheels, which is convenient for the user to move the device. After moving to the desired position, the support rod 201 can be reversed so that the support rod 201 drives the support plate 202 to move downward and support the base plate 1 again, thereby improving the stability of the base plate 1 during use. By providing the rubber pad 10, the friction between the support plate 202 and the ground is improved.

[0028] like Figure 1 and Figure 3 As shown, the placement mechanism 8 includes a crossbar 801, a spacer 802 is fixedly connected to the inner cavity of the crossbar 801, a moving rod 803 is slidably connected to the inner cavity of the crossbar 801, and a vertical rod 804 is fixedly connected to the bottom of the moving rod 803;

[0029] The bottom of the crossbar 801 is fixedly connected with a fixing block 805, and the inner cavity of the fixing block 805 is threadedly connected with a fixing bolt 806; the moving rod 803 is close to one side of the inner cavity of the crossbar 801, and the fixing bolt 806 on the other side is tightened to fix the moving rod 803 between the inner cavity of the crossbar 801 and the fixing bolt 806. The front end of the fixing bolt 806 is provided with a gasket whose outer diameter is larger than the diameter of the fixing bolt 806, and the gasket can prevent the fixing bolt 806 from falling off and can also increase the contact area of ​​the front end.

[0030] The inner cavity of the moving rod 803 is slidably connected to the stabilizing rod 11, one end of which is fixedly connected to one side of the spacer 802, and the distance between the stabilizing rod 11 and the inner cavity of the cross bar 801 is greater than half of the outer diameter of the moving rod 803, so that the moving rod 803 has a moving gap with the inner cavity of the cross bar 801 after installation.

[0031] It should be noted that: when the photoelectric sensor 9 is installed at the casting equipment, in order to adapt to casting equipment of different sizes, the user can rotate the fixing bolt 806 to move the fixing bolt 806 downward to release the fixation of the moving rod 803, and then the user can pull the moving rod 803 to adjust the distance between the two vertical rods 804 to adapt to casting equipment of different sizes. After adjusting to the desired position, the fixing bolt 806 can be returned to its place to re-fix the moving rod 803. By setting the stabilizing rod 11, the stability of the moving rod 803 during movement is improved.

[0032] Working principle: When using this device, the pressure tube 6 can be connected to the casting box in the casting equipment, and the photoelectric sensor 9 can be set up at the casting equipment through the placement mechanism 8. The distance of the slurry is measured by the photoelectric sensor 9. A small distance means there is material, and a large distance means there is no slurry. The photoelectric sensor 9 detects the obtained signal and transmits the signal to the external PLC. When there is no slurry, the external PLC controls the solenoid valve 7 to operate, and pressurizes the casting box through the pressure tank 3 to facilitate the discharge of the slurry.
