Description

Technical Field

[0001] The utility model relates to the technical field of depolymerization kettles, in particular to a depolymerization kettle with a liquid level measurement function. Background Art

[0002] A depolymerization reactor is a key piece of equipment used in the chemical and pharmaceutical industries, primarily for the depolymerization of polymers. This equipment decomposes long-chain polymers into monomers or oligomers through heating, stirring, and pressure control. Typically constructed from high-strength metal materials, the reactor can withstand high temperatures and high pressures. The liquid level in a typical depolymerization reactor is controlled by a level sensor installed on the reactor to monitor the liquid level in real time. The level signal measured by the sensor automatically or manually controls the opening and closing of a control valve.

[0003] However, when the depolymerization kettle is stirred, violent fluctuations will occur inside the liquid, making it difficult for traditional liquid level measurement devices to provide accurate readings. The fluctuation of the liquid level may cause measurement errors, which in turn affects the precise control of the liquid in the depolymerization kettle, resulting in liquid level deviations in the process flow, affecting product quality and production efficiency.

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

[0018] See also Figure 1The embodiment of the utility model provides a depolymerization kettle with a liquid level measurement function, comprising: a depolymerization kettle 1, the top of the depolymerization kettle 1 is connected to a feed pipe 13, and the bottom of the depolymerization kettle 1 is connected to a discharge pipe 9.

[0019] Among them, such as Figure 1-Figure 3 As shown, a radar level gauge 14 is installed on the top of the depolymerization kettle 1, a fixed cylinder 3 is installed on the inner wall of the bottom of the depolymerization kettle 1, and a plurality of liquid inlets 4 are arranged equidistantly on the outer wall of the fixed cylinder 3. A sleeve 5 is slidably installed inside the fixed cylinder 3, and the top opening of the sleeve 5 is located at the bottom of the radar level gauge 14. By installing the radar level gauge 14 on the top of the depolymerization kettle 1 and setting the detection end toward the top of the sleeve 5, the radar level gauge 14 can monitor the liquid levels in the fixed cylinder 3 and the sleeve 5.

[0020] Furthermore, a motor 10 is installed on the top of the depolymerization kettle 1. The rotating shaft of the motor 10 passes through the top of the depolymerization kettle 1 and is fixedly connected to a stirring blade 11. The stirring blade 11 is driven to rotate by the motor 10 to stir and mix the raw materials inside the depolymerization kettle 1. A mask 2 is installed on the top of the depolymerization kettle 1. The motor 10 is located inside the mask 2. The mask 2 can cover and protect the motor 10.

[0021] In this embodiment, as 1 and Figure 3 As shown, one end of the top of the sleeve 5 is fixedly connected to a ring-shaped floating plate 6, the inner wall of the fixed cylinder 3 is symmetrically provided with two sliding grooves 16, and the outer wall of the sleeve 5 is symmetrically provided with two convex ridges 15, which are slidably installed inside the sliding grooves 16.

[0022] During use, the liquid in the depolymerization kettle 1 can enter the fixed cylinder 3 through the liquid inlet 4, and the sleeve 5 can be raised and lowered according to the change of the liquid level by using the annular floating plate 6. When the depolymerization kettle 1 is performing a stirring operation, the fluctuation of the liquid will cause unstable liquid level measurement. The fixed cylinder 3 is fixedly installed on the bottom inner wall of the depolymerization kettle 1, and cooperates with the sleeve 5 to reduce the direct fluctuation of the liquid during stirring.

[0023] like Figure 3 As shown, the outer wall of the sleeve 5 is provided with a number of threaded holes 7 arranged at equal intervals, and the outer wall of the fixing cylinder 3 is penetrated by a threaded rod 8. The operator can also connect the threaded rod 8 to the threaded hole 7 on the outer wall of the sleeve 5, and remove the annular floating plate 6, reducing accessories and completing the manual adjustment of the height of the sleeve 5.

[0024] Specifically, in order to reduce the increase in the temperature of the outer wall of the depolymerization vessel 1 caused by the excessively high temperature inside the depolymerization vessel 1 , the outer wall of the depolymerization vessel 1 is covered with a heat insulation cover 12 .

[0025] According to the above technical solution, the working steps of this solution are summarized and sorted out: when in use, a sleeve 5 is slidably installed in the fixed cylinder 3 at the bottom of the depolymerization kettle 1, and the radar level gauge 14 is installed on the top of the depolymerization kettle 1, and the detection end is set toward the top of the sleeve 5, so that the radar level gauge 14 can monitor the liquid level in the fixed cylinder 3 and the sleeve 5. When the liquid level reaches the set value, the radar level gauge 14 can send a detection signal to facilitate the subsequent control of the liquid level in the depolymerization kettle 1.

[0026] The liquid in the depolymerization kettle 1 can enter the fixed cylinder 3 through the liquid inlet 4, and the sleeve 5 can be raised and lowered according to the change of the liquid level using the annular float 6. When the depolymerization kettle 1 is stirring, the fluctuation of the liquid will cause unstable liquid level measurement. The fixed cylinder 3 is fixedly installed on the bottom inner wall of the depolymerization kettle 1, and cooperates with the sleeve 5 to reduce the direct fluctuation of the liquid during stirring, effectively maintaining the stability of the liquid level in the fixed cylinder 3 and the sleeve 5, thereby ensuring that the detection results of the radar level meter 14 are accurate and reliable.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
