Abstract
Description
Technical Field
[0001] This utility model belongs to the field of evaporator technology, specifically relating to a feeding device for an evaporator. Background Technology
[0002] An evaporator is an industrial device used to concentrate solutions. It increases the concentration of the solute or recovers the solvent by heating the solvent (usually water). It is widely used in chemical, food, pharmaceutical, environmental protection, and seawater desalination industries. When using an evaporator, a feed pipe connected to a pump is used to input the liquid for evaporation, and the evaporator is continuously supplied during the evaporation process.
[0003] Currently, during the use of an evaporator, as the liquid evaporates, impurities in the liquid are easily adsorbed onto the inner wall of the evaporator. Impurities adsorbed on the heater side can block heat, and prolonged heating of impurities can cause them to turn black, affecting the evaporating liquid. Utility Model Content
[0004] (1) Technical problems to be solved
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a feeding device for an evaporator. The feeding device for the evaporator aims to solve the technical problems in the prior art that impurities in the liquid are easily adsorbed on the inner wall of the evaporator, impurities adsorbed on the heater side will block heat, and impurities will turn black after being heated for a long time, affecting the evaporation liquid.
[0006] (2) Technical solution
[0007] To solve the above-mentioned technical problems, this utility model provides a feeding device for an evaporator, including an evaporator tank and a top cover fixedly installed on the top of the evaporator tank. A steam output pipe is welded and fixed to the top of the top cover, and a feeding pipe is embedded and fixed in the top cover. A rotating pipe is rotatably connected to the bottom of the feeding pipe. Cleaning mechanisms for cleaning the inner wall of the evaporator tank are fixed at equal intervals on both sides of the outer wall of the rotating pipe, and a rotational force conveying mechanism is fixed at equal intervals on the rotating pipe.
[0008] When using this technical solution, a feed pipe is embedded in the top cover of the evaporator. When the feed pipe is conveying liquid, the force of the liquid discharged from the outlet pipe causes the rotating pipe to rotate at the bottom of the feed pipe. The evaporated liquid discharged from multiple outlet pipes can fully contact the spiral heater on the inner wall of the evaporator. During the rotation of the rotating pipe, the connecting rod and scraper drive the impurities adsorbed on the inner wall of the evaporator to clean them, thereby greatly reducing the impurities remaining on the inner wall of the evaporator and avoiding the problem of impurities blocking the heat of the heater and affecting the evaporated liquid.
[0009] Preferably, the bottom end of the evaporator is welded and fixed with support legs in a ring array, and a drain pipe is fixed at the center of the bottom end face of the evaporator, with a control valve installed on the drain pipe.
[0010] Furthermore, the top end of the feed pipe passes through the steam output pipe and protrudes above the steam output pipe, and the outer wall of the feed pipe is welded with crossbars fixed to the top cover in a ring array.
[0011] Furthermore, the top end of the rotating tube is integrally formed with a protrusion that is rotatably engaged in the feed tube.
[0012] Furthermore, the bottom of the evaporator is provided with an equipment compartment, in which a spiral heater is embedded. The inner wall of the equipment compartment is welded and fixed with heat-conducting fins fitted onto the spiral heater, and a control box for controlling the spiral heater is fixedly installed on the outer wall of the evaporator.

[0015] (3) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention features an inlet pipe embedded in the top cover of the evaporator. When the liquid is being transported, the force of the liquid discharged from the outlet pipe causes the rotating pipe to rotate at the bottom of the inlet pipe.

Figures 1 to 4 As shown, it includes an evaporator 1 and a top cover 4 fixedly installed on the top of the evaporator 1. A steam output pipe 3 is welded and fixed to the top of the top cover 4, and a feed pipe 2 is embedded and fixed in the top cover 4. A rotating pipe 10 is rotatably connected to the bottom end of the feed pipe 2. Cleaning mechanisms for cleaning the inner wall of the evaporator 1 are fixed at equal intervals on both sides of the outer wall of the rotating pipe 10, and a rotational force conveying mechanism is fixed at equal intervals on the rotating pipe 10.
[0027] The bottom of the evaporator 1 is welded with support legs 6 in a ring array, and a drain pipe 7 is fixed at the center of the bottom end face of the evaporator 1. A control valve is installed on the drain pipe 7. After the control valve is opened, the waste liquid generated by evaporation is discharged.
[0028] The top end of the feed pipe 2 passes through the steam output pipe 3 and protrudes above the steam output pipe 3. The outer wall of the feed pipe 2 is welded with crossbars 11 that are fixed to the top cover 4 in a ring array. The crossbars 11 keep the bottom end of the feed pipe 2 at a certain temperature. A cavity for steam to pass through is provided between multiple crossbars 11. The steam output pipe 3 is connected to a pipe (not shown in the figure) through a flange.
[0029] The top end of the rotating tube 10 is integrally formed with a protrusion 9 that is rotatably engaged in the feed tube 2. In order to further improve the rotation efficiency between the protrusion 9 and the feed tube 2, a sealed bearing is installed between the protrusion 9 and the feed tube 2.
[0030] An equipment compartment 8 is provided at the bottom of the evaporator 1. A spiral heater 14 is embedded in the equipment compartment 8. A heat-conducting plate 13 fitted on the spiral heater is welded and fixed to the inner wall of the equipment compartment 8. A control box 5 for controlling the spiral heater 14 is fixedly installed on the outer wall of the evaporator 1. The control box 5 is model MCC-200, and the spiral heater 14 is model HX-SP-304.

The evaporated liquid discharged from multiple outlet pipes 17 can fully contact the spiral heater 14 on the inner wall of the evaporator 1. During the rotation of the rotating pipe 10, the connecting rod 15 and the scraper 12 drive the impurities adsorbed on the inner wall of the evaporator 1 to clean them, thereby greatly reducing the impurities remaining on the inner wall of the evaporator 1 and avoiding the problem of impurities blocking the heat of the heater and affecting the evaporated liquid.
