Description

Technical Field

[0001] This invention relates to the field of evaporation equipment technology, and more particularly to an evaporator with a scraping structure. Background Technology

[0002] Scaling is a common problem in the evaporation and concentration process during evaporator operation, which can cause significant economic losses. It reduces the heat transfer coefficient, lowers evaporation efficiency, increases pipeline pressure loss, increases steam consumption, and raises the overall maintenance costs of the evaporator.

[0003] The prior art discloses a novel evaporator with application number 201810911418.6. The evaporator has triangular support legs at the bottom, a mounting plate on the left side of the triangular support legs, a heat exchanger on the top of the mounting plate, and the top right side of the heat exchanger connected to the evaporator via a heat transfer pipe. A water storage tank is located on the top left side of the evaporator. A spray plate device is located on the top left side of the evaporator. A water pump is located on the right side of the bottom of the water storage tank. The water pump is connected to the spray plate device via a water guide pipe. A drive motor is located at the bottom of the evaporator. A wire mesh demister is fitted onto the outer wall of the rotating shaft. Two sets of crossbars are provided on the outer wall of the rotating shaft. Scraping devices are provided at the left and right ends of the crossbars. A discharge port is located at the bottom of the evaporator. A control valve is located at the bottom of the discharge port. An air outlet is located at the top of the evaporator. However, this technology cannot clean the inner wall of the evaporator. During the extraction of the medicine, the residue and sugary slurry tend to stick to the inner wall of the evaporator, making it difficult to complete the descaling work inside the evaporator by scraping alone, resulting in incomplete descaling.

[0004] Therefore, it is necessary to propose an improvement to overcome the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by providing an evaporator with a scraping structure, which solves the problems of incomplete descaling and low descaling efficiency in the prior art.

[0006] The technical solution of this invention is: An evaporator with a scraping structure includes: The first lifting assembly, the first drive motor, the brush, and the housing are provided. The first lifting assembly is located on the housing, the first drive motor is located on the first lifting assembly, the output end of the first drive motor is connected to a rotating shaft, a connecting rod steering assembly is provided on one side of the rotating shaft that extends into the housing, the brush is located on the connecting rod steering assembly, a support baffle for positioning the connecting rod steering assembly is provided on the rotating shaft, a steering groove for steering the connecting rod steering assembly is provided in the housing, and the brush can fit and separate from the inner side of the housing. The housing is equipped with a scraper and a second lifting assembly for raising and lowering the scraper. The outer side of the scraper fits against the inner side of the housing, and the scraper has a through hole for passing through the brush and the connecting rod steering assembly.

[0007] Through the above technical solution, the brush rotates via a linkage steering assembly, allowing it to engage and disengage with the inner side of the enclosure for cleaning. As the brush rotates and separates from the inner side, the distance between the brush and the enclosure increases, and the scraper is raised and lowered via a second lifting assembly. The scraper passes through the gap between the brush and the inner side of the enclosure, scraping and removing scale from the inner side. The combined use of the brush and scraper achieves both cleaning and scraping of the inner side of the enclosure, ensuring thorough and clean descaling.

[0008] Furthermore, the linkage steering assembly includes a first hinge seat, a second hinge seat, a first support rod, and a second support rod. Both the first hinge seat and the second hinge seat are located on the rotating shaft. The first support rod is hinged to the first hinge seat, and the second support rod is hinged to the second hinge seat. A hinge rod is hinged between the first support rod and the second support rod, and the brush is located on the hinge rod.

[0009] The first support rod, the second support rod, the hinge rod, and the rotating shaft form a parallelogram structure. The first support rod and the second support rod rotate around the first hinge seat and the second hinge seat on the rotating shaft, respectively, thereby driving the hinge rod to rotate and realizing the contact or separation of the brush with the inner side of the box.

[0010] Furthermore, the support baffle is located at the bottom of the first hinge seat and is used for horizontal positioning when the first support rod rotates, ensuring that the brush is in contact with the inner side of the box, so as to facilitate the cleaning operation of the inner side of the box.

[0011] Furthermore, the steering groove is located below the second hinge seat, and the steering groove corresponds to the rotating shaft.

[0012] The rotating shaft moves up and down via the first lifting assembly. When the rotating shaft moves downward, the bottom of the rotating shaft enters the steering groove. The upper edge of the steering groove blocks the second support rod. The second support rod rotates upward and drives the first support rod to rotate upward at the same time, thereby driving the brush to rotate upward. The distance between the brush and the inner side of the box increases, making it easier for the scraper to pass through the distance between the brush and the inner side of the box to perform scraping and descaling operations on the inner side of the box.

[0013] To prevent the steering groove from jamming the second support rod, the upper edge of the steering groove is provided with an outwardly expanding rounded corner to support the second support rod and ensure the stability of the second support rod when it rotates.

[0014] Furthermore, the first lifting assembly includes a lifting cylinder, which is mounted on the housing. The first drive motor is mounted on the piston rod of the lifting cylinder. The first drive motor is driven to lift and move via the lifting cylinder, and the rotation is driven by the first drive motor to move the brush.

[0015] The lifting cylinder can also be an electric lifting rod, a hydraulic cylinder, or other lifting components, used for the lifting and moving of the first drive motor.

[0016] Furthermore, the second lifting assembly includes a second drive motor and a threaded rod. The second drive motor is mounted on the housing, one end of the threaded rod is connected to the output shaft of the second drive motor, and the other end of the threaded rod is rotatably connected to the housing. The scraper is threadedly connected to the threaded rod.

[0017] The second drive motor drives the threaded rod to rotate, and the scraper moves up and down with the rotation of the threaded rod.

[0018] Furthermore, a high-pressure water pipe is connected to the housing, and a water distribution pipe is provided inside the housing. The water distribution pipe is equipped with a high-pressure nozzle for spraying cleaning fluid into the housing during descaling, thereby improving descaling efficiency.

[0019] Furthermore, the chamber is equipped with a heat exchanger, which is connected to a high-pressure steam pipe and a condensate pipe for heating the evaporating liquid inside the chamber.

[0020] Furthermore, the housing is connected to an exhaust pipe for the discharge of steam.

[0021] Furthermore, the box body is equipped with a discharge pipe, and the discharge pipe is equipped with a discharge valve for discharging the liquid material inside the box body.

[0022] Compared with the prior art, the beneficial effects of the present invention are: The evaporator with a scraping structure of the present invention, by setting up a first drive motor, a first lifting component, a brush, and a rotating shaft, realizes the lifting and rotation of the brush within the chamber. The brush adheres to the inner side of the chamber and rotates to scrub the inner side of the chamber, cleaning up the medicinal residue and sugar adhering to the inner side of the chamber. By setting up a scraper and a second lifting component, the scraper moves up and down within the chamber to scrape the inner side of the chamber, removing larger dirt particles. Through the cooperation of the brush and the scraper, the scrubbing and scraping of the evaporator are realized, improving the descaling efficiency of the evaporator and ensuring a more thorough and clean descaling process.

[0025] To make the technical means, technical features, inventive purpose and technical effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0026] like Figure 1-3 The figure shown is an overall schematic diagram of the evaporator with a scraping structure according to the present invention.

[0027] The evaporator with a scraping structure shown includes a housing 12, which is generally circular. A lifting cylinder 14 is fixed to the upper surface of the housing 12. A first drive motor 13 is fixed to the top of the piston rod of the lifting cylinder 14. A rotating shaft 10 is connected to the output shaft of the first drive motor 13. The rotating shaft 10 passes through the upper surface of the housing 12 and extends into the housing 12. Inside the housing 12, the rotating shaft 10 is fixed from top to bottom with a first hinge seat 19, a support baffle 4, and a second hinge seat 21. The support baffle 4 is horizontally fixed to the lower surface of the first hinge seat 19, and the outer diameter of the support baffle 4 is larger than that of the first hinge seat 19. The outer diameter of a hinge seat 19 is such that four sets of first support rods 3 are hinged at equal angles on the first hinge seat 19, and four sets of second support rods 6 are hinged at equal angles on the second hinge seat 21. All four sets of first support rods 3 and four sets of second support rods 6 are vertically aligned. A hinge rod 23 is hinged between each set of first support rods 3 and second support rods 6. A brush 5 is fixedly installed at the outer edge of the hinge rod 23. The hinge rod 23 and the rotating shaft 10 form a parallelogram. When the first support rods 3 and second support rods 6 are horizontal, the outer surface of the brush 5 is in contact with the inner surface of the housing 12. When the first support rods 3 and second support rods 6 rotate upwards, the outer surface of the brush 5 separates from the inner surface of the housing 12 by a certain gap.

[0028] A fixing frame 8 is fixed inside the housing 12. The fixing frame 8 is fixed below the brush 5. A turning groove 7 is fixed at the center of the fixing frame 8. The upper edge of the turning groove 7 is a rounded corner that expands outward. The turning groove 7 is fixed directly below the rotating shaft 10. The rotating shaft 10 is driven by the lifting cylinder 14 and can move downward into the turning groove 7. The second support frame 6 is blocked by the upper edge of the turning groove 7 and rotates upward, driving the second support frame 3 and the hinge rod 23 to rotate upward synchronously. The outer side of the brush 5 separates from the inner side of the housing 12.

[0029] A second drive motor 16 is fixed on opposite sides of the upper end face of the housing 1. Threaded rods 20 are connected to the output shafts of both second drive motors 16. Both threaded rods 20 are installed inside the housing 12. Mounting seats 22 are fixed on opposite sides of the fixing bracket 8. The lower ends of the two threaded rods 20 are rotatably connected to the two mounting seats 22 respectively. Scraper blocks 18 are installed on the two threaded rods 20. Threaded holes 27 are opened on opposite sides of the scraper blocks 18. The scraper blocks 18 are threadedly connected to the threaded rods 20 through the threaded holes 27. A through hole 26 is opened in the middle of the scraper blocks 18. When the brush 5 rotates upward, the scraper blocks 18 move downward and pass through the brush 5 through the through hole 16.

[0030] A heat exchanger 29 is installed at the lower end of the housing 12. A high-pressure steam pipe 11 and a condensate pipe 28 are connected to the heat exchanger 29. The high-pressure steam pipe 11 is used for the input of high-pressure steam, and the condensate pipe 28 is used for the discharge of condensate. The high-pressure steam pipe 11 is connected to the side of the housing 12, and the condensate pipe is connected to the lower end face of the housing 12. A heater is connected between the high-pressure steam pipe 11 and the condensate pipe 28 on the outside of the housing 12 to provide high-pressure steam. A raw material inlet pipe 30 is also connected to the side of the housing 12 for inputting raw material liquid into the housing 12.

[0031] A discharge pipe 24 is fixedly installed at the bottom of the tank 12, and a discharge valve 25 is installed on the discharge pipe 24 to control the discharge of liquid material in the tank 12.

[0032] A base 9 is fixed to the lower end of the housing 12 for support of the housing 12 and to facilitate the installation of pipes.

[0033] like Figure 4 The diagram shown is a schematic of the brush 5 of the present invention after it is rotated upwards.

[0034] The brush 5 is driven to rotate by the first drive motor 13 to clean the inner surface of the housing 12. After cleaning, the rotating shaft 10 is driven to move downward by the lifting cylinder 14. The rotating shaft 10 moves into the turning groove 7, and the second support rod 6 rotates upward by the obstruction on the upper edge of the turning groove 7. The first support rod 3 and the hinge rod 26 rotate upward synchronously, and the brush 5 separates from the inner surface of the housing 12. The distance between the outer surfaces of the brushes 5 on both sides is less than the diameter of the through hole 26. Then, the scraper 18 is driven to move downward by the second drive motor 16 to scrape the inner surface of the housing 12. The brush 5 and the scraper 18 work alternately to clean and scrape the inner surface of the housing 12, ensuring that the scale is removed cleanly.

[0035] The first drive motor 13 moves upward, and the first support rod 3 and the second support rod 6 both rotate downward. When the first support rod 3 rotates the upper end face of the support baffle 4, the first drive motor 13 stops moving. A stable parallelogram structure is formed between the first support rod 3, the hinge rod 26 and the second support rod 6. Then, driven by the first drive motor 13, the inner side of the box 12 is cleaned.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the scope of the claims of this invention should fall within the technical scope of this invention.
