[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0026] In related technologies, a metering tank is a device for holding liquid catalysts. Metering tanks are commonly used in the production of hydrated catalysts to count the amount of catalyst used. For example, patent CN221280339U discloses a metering device for the production of hydrated catalysts. The metering tank 10 has an inlet 11 at the top and a drain pipe 12 at the bottom. The amount of hydrated catalyst used is measured by a flow meter 13 on the drain pipe 12. To seal the inlet 11, a sealing cap 20 is screwed on at the inlet 11. However, during stirring, material splashes and contaminates the sealing cap.

[0027] In view of this, this embodiment provides a metering device for the production of hydrated catalysts to avoid the sealing cap coming into contact with the material.

[0028] Please refer to Figures 1-3. In this embodiment, a metering device for the production of hydration catalyst includes a metering tank 10, a feed inlet 11, a drain pipe 12, and a flow meter 13. A support plate 30 with a feed hole 31 is fixedly connected inside the feed inlet 11. A guide post 32 is provided on the support plate 30, and a sliding sleeve 41 is sleeved on the guide post 32. The sliding sleeve 41 abuts against a compressed spring 34 inside the guide post 32. A sealing plate 40 corresponding to the feed hole 31 is provided on the sliding sleeve 41. After the sealing cover 20 is screwed into the feed inlet 11, it can press the sealing plate 40 into the feed hole 31.

[0029] In this embodiment, an inlet hole 31 and a sealing plate 40 are added inside the inlet 11. The sealing plate 40 can be pressed into the inlet hole 31 by the sealing cover 20, thereby isolating the sealing cover 20 from the material inside the metering tank 10 and preventing the sealing cover from contacting the material.

[0030] It should be noted that this embodiment is a structural improvement of the metering tank disclosed in patent CN221280339U. The main improvement is in the feed inlet. Compared with the feed inlet of the existing metering tank, the feed inlet of this embodiment is equipped with an inlet hole and a corresponding sealing plate. The sealing plate is movable and can be pressed into the inlet hole by the sealing cover during the process of screwing the sealing cover into the feed inlet, thereby sealing the inlet hole and isolating the sealing cover from the material inside the metering tank, preventing the sealing cover from contacting the material.

[0031] The feed inlet structure of this embodiment will be described in detail below with reference to the accompanying drawings.

[0032] In this embodiment, the support plate 30 is constructed as a disk shape arranged coaxially with the feed port 11. The feed hole 31 is formed on the support plate 30 and is constructed as a fan shape arranged coaxially with the support plate 30. The feed hole 31 is evenly arranged along the circumference of the support plate 30.

[0033] In addition, a guide post 32 is fixed to the upper surface of the support plate 30, and the guide post 32 is coaxially arranged with the support plate 30. The guide post 32 has a hollow structure. A limiting groove 33 is provided on the side wall of the guide post 32, and the limiting groove 33 is arranged parallel to the axis of the guide post 32. Two limiting grooves 33 are evenly arranged along the circumference of the guide post 32. A spring 34 is provided in the inner cavity of the guide post 32. At the same time, a sealing plug 35 is screwed on the top of the guide post 32.

[0034] In addition, a sliding sleeve 41 is sleeved on the outside of the guide post 32. A limiting plate 42 is fixedly connected to the top of the sliding sleeve 41. The limiting plate 42 is slidably engaged inside the limiting groove 33 and is arranged along the diameter direction of the guide post 32. The limiting plate 42 abuts against the top of the spring 34. A sealing plate 40 is fixedly connected to the lower end of the sliding sleeve 41. The sealing plate 40 is adapted to the shape of the feed hole 31 and is also constructed in a fan shape. The sealing plate 40 and the feed hole 31 are arranged in a one-to-one correspondence. The sealing plate 40 can move into the feed hole 31 and close the feed hole 31.

[0035] It should be noted that, under the elastic force of the spring 34, the sealing plate 40 is located above the support plate 30, and a material flow channel is formed between the two, which facilitates the addition of materials into the metering tank 10 through the feed inlet 11; when the sealing cover 20 is rotated into the feed inlet 11, the sealing cover 20 will push the sealing plate 40 downward until the sealing plate 40 moves into the feed hole 31 and closes the feed hole 31. At this time, the support plate 30 and the sealing plate 40 form a partition that separates the feed inlet 11.

[0036] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
