DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A lye metering tank for producing hydroxypropyl methylcellulose comprises a tank body 1, a sealing top cover 2 is provided at the top position of the tank body 1, a liquid level transmitter 3 is fixedly installed at the middle position of the top of the sealing top cover 2, a connecting wire body 4 is provided at the bottom position of the liquid level transmitter 3, a liquid level sensor body 9 is provided at the bottom position of the connecting wire body 4, mesh covers 5 are respectively provided at both sides of the outside of the connecting wire body 4, a limiting semi-ring 6 is fixedly connected to the bottom end of the mesh cover 5, a connecting rod 7 is fixedly connected to the inner side of the limiting semi-ring 6, a clamping ring 8 is fixedly connected to the side of the connecting rod 7 away from the limiting semi-ring 6, a limiting chuck 10 is fixedly connected to the top of the mesh cover 5, and a sliding block 11 is fixedly connected to the top of the limiting chuck 10.

[0020] like Figure 1 As shown, a liquid outlet pipe 16 is connected to the bottom position of the tank body 1, and the lower half of the tank body 1 is arranged in a conical structure, an outer sleeve of the tank body 1 is provided with an outer clamping ring 17, and a support column 18 is fixedly connected to the bottom of the outer clamping ring 17. When the metering operation is completed and the hydroxypropyl methylcellulose is taken out through the liquid outlet pipe 16, the conical structure of the lower half of the tank body 1 makes the entire taking-out operation more centralized; a liquid inlet pipe 15 is provided at one side position of the top end of the sealing top cover 2, and a conductive setting is set between the liquid inlet pipe 15 and the tank body 1, and the connecting wire body 4 and the liquid level sensor body 9 extend into the interior of the tank body 1 respectively. Under the setting of mutual conduction, the entire device can quickly introduce the refined hydroxypropyl methylcellulose into the interior of the tank body 1 through the liquid inlet pipe 15.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, the mesh cover 5 is symmetrically arranged along the vertical center axis of the sealing top cover 2, and the mesh cover 5 is arranged in a semi-annular structure. The mesh cover 5 and the limiting chuck 10 are coaxially arranged. When the extrusion limiting structure squeezes and limits the connecting wire body 4, a group of mesh covers 5 will cover the connecting wire body 4, which will play a filtering and protective role from the outside of the connecting wire body 4 when the hydroxypropyl methylcellulose is introduced into the interior of the tank body 1; the connection between the clamp ring 8 and the connecting rod 7 forms a "Y"-shaped structure, and there is a group of clamp rings 8. The bottom end surface of the sealing top cover 2 is provided with a slide groove 12, and the sealing The capping cover 2 is slidably connected to the slider 11 through a slide groove 12, a guide rod 13 is provided on the inner side of the slide groove 12, and the guide rod 13 and the slider 11 are slidably connected, a spring 14 is sleeved on the outer side of one side of the guide rod 13, and both side ends of the spring 14 are respectively connected to the slider 11 and the sealing top cover 2. After the metering structure is deeply installed and the outward traction force on a group of mesh covers 5 is removed, the limiting chuck 10 will use the rebound potential energy generated by the spring 14 through the slider 11, so that a group of mesh covers 5 and the extrusion limiting structure can be forced to rebound and reset, thereby realizing the corresponding external protection and extrusion limiting operations.

[0022] Workflow: The electric energy required for the startup and operation of the equipment in the utility model comes from an external power supply. When using the alkali liquid metering tank for the production of hydroxypropyl methylcellulose, first, as the refined hydroxypropyl methylcellulose passes through the liquid inlet pipe 15, it is gradually introduced into the interior of the tank body 1. Under the action of the outer protection and extrusion limiting structure of the left and right sets of mesh covers 5, the entire alkali liquid metering tank will measure and monitor the hydroxypropyl methylcellulose through the liquid level sensor body 9, and display the monitored data through the liquid level transmitter 3, thereby achieving the purpose of measuring the hydroxypropyl methylcellulose. The above technical scheme for metering and detection is a publicly available prior art. Finally, after the metering operation is completed, the hydroxypropyl methylcellulose can be discharged through the inside of the liquid outlet pipe 16. Because before the metering component is installed, A group of mesh covers 5 can be pushed outward in reverse by manual operation, so that the extrusion limiting structure composed of the limiting half ring 6, the connecting rod 7 and the clamp ring 8 is opened, so that the metering component can penetrate into the interior of the tank body 1. When the liquid level sensor body 9 is connected to the liquid level transmitter 3 through the connecting wire body 4 and is gradually lowered into the interior of the tank body 1, the outward traction force on the group of mesh covers 5 can be removed, so that the limiting chuck 10 can rebound and reset toward the middle position of the tank body 1 with the help of the rebound potential energy generated by the spring 14 through the slider 11, until the extrusion limiting structure squeezes and limits the connecting wire body 4 through a group of clamp rings 8, so that the metering structure is squeezed and limited, and it is prevented from swinging left and right inside the tank body 1 and hitting the inner wall, thereby achieving the purpose of protecting the metering component.
