Description

Technical Field

[0001] The utility model relates to the technical field of salt-making equipment, in particular to a device for conveniently monitoring the pressure state of a multi-effect evaporation chamber. Background Technique

[0002] The multi-effect evaporation salt-making method is an efficient and energy-saving salt-making process. It uses an evaporation concentration and crystallization system to remove or crystallize and precipitate inorganic salts in the waste liquid by evaporation. The main equipment of the multi-effect evaporation salt-making method is a multi-effect evaporation chamber, which is composed of a plurality of evaporators (or called evaporation chambers) connected in series. These evaporators are arranged in a certain order, and the steam of the previous evaporator is used as the heat source of the next evaporator to form a multi-stage utilization of heat energy. During the use of the multi-effect evaporation chamber, pressure state monitoring is a key link to ensure the smooth progress of the operation; by monitoring the pressure state, the progress of the evaporation process can be understood, and process parameters such as the flow rate and temperature of the heating steam can be adjusted in time to ensure the smooth progress of the evaporation process and the effective extraction of salt.

[0003] Each evaporator is directly installed with a precise pressure sensor or pressure gauge. Such monitoring equipment is embedded in the evaporator structure to accurately capture the pressure changes inside the evaporator; however, when installing the pressure sensor or pressure gauge, the probe part of the equipment penetrates deep into the evaporator to reflect the internal pressure state in real time and accurately, while its main body is fixed to the outer wall of the evaporator through fasteners such as bolts. Although this design is efficient, the exposed equipment main body is directly exposed to the external environment, including possible physical collisions, accidental scratches, and erosion by harsh climate conditions. Over time, these external factors may cause damage or performance degradation of the monitoring equipment, thereby affecting the accuracy and reliability of pressure monitoring. In view of this, we propose a device for conveniently monitoring the pressure state of a multi-effect evaporation chamber. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] This embodiment provides a technical solution:

[0031] Please refer to Figures 1-4As shown in the figure, a device for facilitating the monitoring of the pressure state of a multi-effect evaporation chamber includes a multi-effect evaporation chamber 1, and the multi-effect evaporation chamber 1 includes a plurality of evaporators; an installation plate 2 is provided at the front side of the plurality of evaporators, and a plurality of protection seats 20 are installed on the rear end face of the installation plate 2. A sealing groove 201 for clamping the evaporator is provided on the rear end face of the protection seat 20, and a protection hole 202 is provided on the inner wall of the sealing groove 201. A wireless pressure sensor 21 for monitoring the internal pressure state of the evaporator is provided at the protection hole 202. The wireless pressure sensor 21 passes through the outer wall of the evaporator and is fixed to the evaporator; a plurality of fixing seats 22 are installed on the front end face of the installation plate 2. Two symmetrically arranged grooves 221 are provided on the front end face of the fixing seat 22. A lead screw 24 is rotatably installed in each of the grooves 221, and the two lead screws 24 are coaxially fixed; a slider 25 is slidably installed in each of the grooves 221. A threaded hole 251 threadedly connected to the lead screw 24 is provided on the slider 25. Fixing rods 26 are fixed to the two opposite end faces of the two sliders 25, and the fixing rods 26 pass through the fixing seat 22; fixing frames 27 are provided at the rear sides of the protection seats 20. The evaporator is located at the opening of the fixing frame 27 and is clamped by the fixing frame 27; two connecting plates 28 are fixed to the front end of the fixing frame 27. The connecting plates 28 pass through the installation plate 2. Fixing holes 281 are provided at the ends of the connecting plates 28, and the fixing rods 26 are inserted and matched with the corresponding fixing holes 281; a display screen 3 for displaying the pressure state inside the evaporator is installed at the left end of the front end face of the installation plate 2.

[0032] In this embodiment, the fixing frame 27 and the connecting plate 28 are of an integrally formed structure, and the overall shape of the fixing frame 27 is arched. The integral forming ensures the stability and strength of the fixing frame 27 and the connecting plate 28, and the arched shape is conducive to fixing with the evaporator through the fixing frame 27.

[0033] In this embodiment, the cross-sectional shape of the sealing groove 201 is arc-shaped, and the sealing groove 201 abuts against the outer wall of the evaporator. The arc-shaped cross-section helps the sealing groove 201 to better fit the outer wall of the evaporator, enhancing the sealing effect, and the abutting design can prevent leakage of rainwater and the like.

[0034] In this embodiment, the protection seat 20 is fixedly connected to the installation plate 2 by bolts, and the protection seat 20 is made of rubber material. The bolt connection facilitates installation and disassembly. The rubber material has elasticity and wear resistance and can provide buffering and protection effects. Therefore, the rubber material can provide better protection for the wireless pressure sensor 21.

[0035] In this embodiment, a strip-shaped groove 220 is provided between the two grooves 221. An adjusting block 23 is rotatably installed in the strip-shaped groove 220, and the lead screw 24 is coaxially fixed to the adjusting block 23. The cross-sectional shape of the adjusting block 23 is regular hexagon, and this design facilitates the rotation of the adjusting block 23, and thus facilitates the rotation of the lead screws 24 on both sides.

[0036] In this embodiment, the slider 25 and the fixed rod 26 are of an integrally formed structure, and the overall shape of the fixed rod 26 is cylindrical. The integrally formed slider 25 and fixed rod 26 have better connection strength and service life, and the cylindrical design is conducive to the cooperation of the fixing holes 281.

[0037] In this embodiment, the cross-sectional shape of the slider 25 is rectangular, and the rear end of the slider 25 is in contact with the inner wall of the groove 221. This design ensures the stability and directionality of the movement of the slider 25, and avoids situations such as rotation caused by the rotation of the lead screw 24.

[0038] It should be added that the winding directions of the threads on the two lead screws 24 in this embodiment are opposite. When the two double-headed lead screws 24 rotate synchronously, the sliders 25 on both sides can move relatively synchronously, facilitating the synchronous relative movement of the fixed rods 26 on both sides, and thus facilitating the disassembly and assembly of the connecting plate 28 and the fixing bracket 27.

[0039] During specific use, the user first inserts the protection hole 202 into the corresponding wireless pressure sensor 21, and the sealing groove 201 is attached to the outer wall of the evaporator. Then, the user passes the opening of the fixing bracket 27 through the evaporator, and makes the connecting plate 28 pass through the mounting plate 2. Subsequently, the user rotates the adjusting block 23, and the adjusting block 23 drives the lead screw 24 to rotate. The sliders 25 on both sides move relatively synchronously towards both sides, and drive the fixed rod 26 to pass through the fixing hole 281, and the fixing bracket 27 is fixed on the evaporator, and the installation is completed.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention, and are not used to limit the present invention.
