Description

Technical Field

[0001] This utility model belongs to the field of molecular sieve processing technology, and more specifically, it relates to a molding pressure control device for improving the compressive strength of molecular sieves. Background Technology

[0002] Molecular sieves, as materials with specific pore structures and adsorption properties, play an important role in various fields such as petrochemicals, air separation, and environmental protection. Their compressive strength is one of the key indicators affecting the application performance and service life of molecular sieves. During the production process of molecular sieves, the control of molding pressure plays a crucial role in the compressive strength of the sieves.

[0003] Traditional molecular sieve forming pressure control devices often have some defects. Some devices have low pressure control accuracy and cannot accurately control the forming pressure, resulting in unstable compressive strength of molecular sieves. Some devices lack flexible pressure adjustment mechanisms and cannot be adjusted according to the characteristics and forming requirements of different molecular sieves.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a molding pressure control device to improve the compressive strength of molecular sieves, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a molding pressure control device for improving the compressive strength of molecular sieves, which is achieved by the following specific technical means:

[0006] A molding pressure regulating device for improving the compressive strength of molecular sieves includes a base, an oil tank, and a solenoid valve. A pressure sensor is mounted on the upper surface of the base, and a mounting base is mounted on the upper surface of the pressure sensor. A lower mold is mounted on the upper surface of the mounting base. Several support rods are mounted on the upper surface of the base. The mounting base is movably connected to the several support rods. A mounting plate is mounted on the top of each support rod. A hydraulic rod is mounted on the upper surface of the mounting plate. The output end of the hydraulic rod passes through the bottom surface of the mounting plate and is mounted on a support plate. The support plate is movably connected to the several support rods. Next, an upper mold is installed on the bottom surface of the support plate, a filter mechanism is installed on one side of the base, an oil pump is installed on the upper surface of the oil tank, the oil pump is connected to the oil tank through an oil supply pipe one, a solenoid valve is installed on the upper surface of the oil tank near the oil pump, the solenoid valve is equipped with an oil supply pipe two, an oil supply pipe three, an oil supply pipe four, and an oil supply pipe five, the solenoid valve is connected to the oil pump through an oil supply pipe two, the solenoid valve is connected to the oil inlet of the hydraulic rod through an oil supply pipe three, the solenoid valve is connected to the oil outlet of the hydraulic rod through an oil supply pipe four, and the solenoid valve is connected to the oil tank through an oil supply pipe five.

[0007] Furthermore, the filtration mechanism includes a filter box, filter screens, and a fan. A pair of filter screens are installed inside the filter box, a fan is installed on one side of the filter box, and a flexible hose is installed on the other side of the filter box.

[0008] Furthermore, a cover is installed on the bottom surface of the support plate, the size of which matches the size of the mounting base, and the other end of the hose is connected to the cover.

[0009] Furthermore, a handle is installed on the upper surface of the filter screen.

[0010] Furthermore, a controller is installed on the upper surface of the fuel tank.

[0011] Furthermore, the pressure sensor is electrically connected to the solenoid valve, controller, and oil pump.

[0012] Furthermore, a heating mechanism is provided inside the lower mold.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By using an oil pump, solenoid valve, hydraulic rod, and pressure sensor in conjunction, the oil pump delivers hydraulic oil to the hydraulic rod through oil supply pipe one, oil supply pipe two, solenoid valve, and oil supply pipe three. The hydraulic rod pushes the upper mold to the position of the lower mold via the support plate. At this time, the pressure sensor transmits a signal to the controller and adjusts the opening of the solenoid valve according to the preset pressure value, thereby controlling the amount of oil entering the hydraulic rod and the forming pressure. This allows for precise control of the molecular sieve forming pressure, significantly improving the compressive strength of the molecular sieve and ensuring its stability and durability under high pressure. At the same time, the use of intelligent pressure regulation achieves efficient allocation and utilization of pressure resources, reducing energy consumption and raw material waste.

[0015] By using the hood, fan, and filter screen in combination, when the upper and lower molds extrude raw materials into molecular sieves and generate smoke and dust, the fan is started. The fan creates negative pressure in the filter box, which allows the smoke and dust inside the hood to be sucked into the filter box through the hose. The filter screen filters the smoke and dust, thereby improving the environmental friendliness of the device. Attached Figure Description

[0027] This utility model provides a molding pressure control device for improving the compressive strength of molecular sieves, including a base 1, an oil tank 2, and a solenoid valve 3. A pressure sensor 4 is installed on the upper surface of the base 1, and a mounting seat 5 is installed on the upper surface of the pressure sensor 4. A lower mold 501 is installed on the upper surface of the mounting seat 5. Several support rods 101 are installed on the upper surface of the base 1. The mounting seat 5 is movably connected to the several support rods 101. A mounting plate 6 is installed at the top of the several support rods 101. A hydraulic rod 7 is installed on the upper surface of the mounting plate 6. A support plate 8 is installed through the bottom surface of the mounting plate 6 at the output end of the hydraulic rod 7. The support plate 8 is movably connected to the several support rods 101. The bottom end of plate 8 is equipped with an upper mold 801. A filter mechanism 9 is installed on one side of base 1. An oil pump 10 is installed on the upper end of oil tank 2. The oil pump 10 is connected to oil tank 2 through oil supply pipe 11. A solenoid valve 3 is installed on the upper end of oil tank 2 near oil pump 10. Oil supply pipes 2, 3, 4, and 5 are installed on solenoid valve 3. Solenoid valve 3 is connected to oil pump 10 through oil supply pipe 2 12. Solenoid valve 3 is connected to the oil inlet of hydraulic rod 7 through oil supply pipe 3 13. Solenoid valve 3 is connected to the oil outlet of hydraulic rod 7 through oil supply pipe 4 14. Solenoid valve 3 is connected to oil tank 2 through oil supply pipe 5 15.

[0028] The filtration mechanism 9 includes a filter box 901, a filter screen 902, and a fan 903. A pair of filter screens 902 are installed inside the filter box 901. A fan 903 is installed on one side of the filter box 901, and a hose 904 is installed on the other side of the filter box 901.

[0029] The support plate 8 has a cover 16 installed on its bottom surface. The cover 16 is matched with the size of the mounting base 5. The other end of the hose 904 is connected to the cover 16. When the upper mold 801 and the lower mold 501 extrude the raw materials into molecular sieves and generate smoke and dust, the blower 903 is started. The blower 903 generates negative pressure in the filter box 901, so that the smoke and dust in the cover 16 can be sucked into the filter box 901 through the hose 904. The filter screen 902 filters the smoke and dust.

[0030] The filter screen 902 has a handle 905 installed on its upper surface, which makes it easy to remove the filter screen 902.

[0031] The controller 17 is installed on the upper surface of the oil tank 2.

[0032] The pressure sensor 4 is electrically connected to the solenoid valve 3, the controller 17 and the oil pump 10. The pressure sensor 4 transmits a signal to the controller 17 and adjusts the opening of the solenoid valve 3 according to the preset pressure value, thereby controlling the amount of oil entering the hydraulic rod 7 and the forming pressure.

[0033] The lower mold 501 is equipped with a heating mechanism 18, which can heat the molecular sieve during the molding process to improve the crystallinity and compressive strength of the molecular sieve.

[0034] The working principle of this embodiment:

[0035] First, the molecular sieve raw material is added to the lower mold 501. Then, the oil pump 10 is started. The oil pump 10 delivers hydraulic oil to the hydraulic rod 7 through oil supply pipe 11, oil supply pipe 2 12, solenoid valve 3, and oil supply pipe 3 13. The hydraulic rod 7 pushes the upper mold 801 to move to the position of the lower mold 501 through the support plate 8. At this time, the pressure sensor 4 transmits a signal to the controller 17 and adjusts the opening of the solenoid valve 3 according to the preset pressure value, thereby controlling the amount of oil entering the hydraulic rod 7 and the molding pressure. When the molding pressure reaches the preset value, it is maintained for a period of time. During this process, the molecular sieve is fully formed and solidified. Then, the controller 17 slowly opens the solenoid valve 3 to discharge the hydraulic oil in the hydraulic rod 7, reducing the forming pressure. When the upper mold 801 and the lower mold 501 extrude the raw materials into molecular sieves and generate smoke and dust, the blower 903 is started. The blower 903 creates negative pressure in the filter box 901, which allows the smoke and dust in the cover 16 to be sucked into the filter box 901 through the hose 904. The filter screen 902 filters the smoke and dust, thereby improving the environmental friendliness of the device.
