Description

Technical Field

[0001] The utility model belongs to the technical field of waste liquid treatment equipment, and in particular relates to a waste liquid evaporation and concentration treatment device. Background Art

[0002] The evaporation and concentration treatment device for waste liquid is a device specially used for treating waste liquid. Its core function is to remove water from the waste liquid through the evaporation process to obtain a concentrate. This device usually includes key components such as an evaporator, a heater, a condenser, and a collector. In the evaporation and concentration treatment process of the waste liquid, the waste liquid is first introduced into the evaporator, and the heater provides heat to evaporate the water in the waste liquid. The evaporated water vapor is then cooled by the condenser and converted into liquid water, while the concentrate remains in the evaporator or is further collected and treated.

[0003] In the existing waste liquid evaporation and concentration treatment device, the stirring mechanism and the scraping mechanism often exist as two independent units, which are respectively used to accelerate the evaporation process and clean the concentrate on the inner wall. The stirring mechanism improves the heat transfer efficiency and promotes the evaporation of water by stirring the waste liquid, while the scraping mechanism regularly or irregularly scrapes the concentrate on the inner wall of the evaporation box to prevent scaling and clogging. The independent operation of the stirring mechanism and the scraping mechanism may cause operational inconvenience and low efficiency. The operating parameters and timing of the two mechanisms need to be controlled separately, which increases the complexity and difficulty of the operation. Improvements are needed. To this end, a waste liquid evaporation and concentration treatment device is proposed. Utility Model Content

[0023] 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 of 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.

[0024] See also Figure 1-7 The utility model provides a technical solution: a waste liquid evaporation and concentration treatment device, comprising an evaporation box 1 and an air outlet pipe 2 arranged on the top of the evaporation box 1, the evaporation box 1 is arranged in an inverted truncated cone shape, the top of the evaporation box 1 is fixedly installed with a mounting plate 3 through a support rod, a rotating motor 4 is fixedly installed on the mounting plate 3, the output shaft end of the rotating motor 4 is slidably provided with a cross plate 5, a spring 11 is fixedly installed in the motor output shaft, the bottom end of the spring 11 is fixedly installed with the top end of the cross plate 5, a rotating rod 6 is rotatably arranged on the top of the evaporation box 1, the rotating rod 6 is fixedly installed on the cross plate 5, a symmetrical stirring rod 7 is fixedly installed on the rotating rod 6, scraping strips 8 are arranged on both sides of the rotating rod 6, the ends of the stirring rod 7 are respectively fixedly installed with the side edges of the scraping strip 8, the scraping strip 8 is arranged in an inclined shape, and the inclination of the scraping strip 8 is the same as the inclination of the inner wall of the evaporation box 1, and a lifting member 9 for driving the rotating rod 6 and the scraping strip 8 to vertically rise and fall is arranged on the evaporation box 1.

[0025] First, the waste liquid to be treated is introduced into the evaporation box 1 through a pipeline. The evaporation box 1 temporarily stores the waste liquid. The heating component is started to heat the waste liquid in the evaporation box 1 to increase the temperature of the waste liquid so that it reaches the conditions required for evaporation. As the temperature of the waste liquid increases, the water in it begins to evaporate. The evaporated water vapor is discharged from the outlet pipe 2. The various components originally existing in the waste liquid form condensates after the water evaporates and remain at the bottom of the evaporation box 1.

[0026] During the evaporation of the waste liquid, the rotating motor 4 on the mounting plate 3 is started, and the output shaft of the rotating motor 4 rotates to drive the cross plate 5, the rotating rod 6, the stirring rod 7 and the scraping bar 8 to rotate simultaneously. The stirring rod 7 and the scraping bar 8 rotate to stir the waste water in the evaporation box 1, thereby accelerating the evaporation of the waste water.

[0027] During the evaporation and concentration process of the waste liquid, some components will be concentrated and adhere to the inner wall of the evaporation box 1. At this time, the lifting member 9 is started, and the lifting member 9 drives the rotating rod 6 and the cross plate 5 to pull the spring 11 to vertically descend on the evaporation box 1. The rotating rod 6 drives the stirring rod 7 and the scraping bar 8 to vertically descend in the evaporation box 1. Since the evaporation box 1 is set to an inverted truncated cone shape, and the inclination of the scraping bar 8 is the same as the inclination of the inner wall of the evaporation box 1, the side of the scraping bar 8 is in contact with the inner wall of the evaporation box 1 during the descent of the scraping bar 8. After the contact, the rotating motor 4 is started to drive the scraping bar 8 to rotate in contact with the inner wall of the evaporation box 1 to scrape off the concentrate adhered to the inner wall of the evaporation box 1. After scraping, the lifting member 9 is restarted to reset, and the scraping bar 8 is pulled away from the inner wall of the evaporation box 1 by the restoring force of the spring 11, and the stirring rod 7 and the scraping bar 8 are driven to rotate again to stir the waste water. During the stirring process, the concentrate on the scraping bar 8 automatically separates from the scraping bar 8 and falls to the bottom of the evaporation box 1;

[0028] The waste liquid evaporation and concentration treatment device combines a stirring mechanism with a scraping mechanism, which can not only stir to accelerate evaporation, but also scrape off the concentrate on the inner wall of the evaporation box 1, thereby ensuring the continuous and efficient operation of the evaporation box 1, and has a simple structure, convenient operation, and strong practicality.

[0029] The lifting member 9 includes a lifting motor 91 fixedly mounted on the mounting plate 3, a screw rod 92 rotatably arranged between the mounting plate 3 and the evaporation box 1, a lifting plate 93 threadedly connected to the screw rod 92, a ring 94 fixedly mounted at one end of the lifting plate 93, and a disc 95 fixedly mounted on the rotating rod 6. The top of the screw rod 92 at the end of the output shaft of the lifting motor 91 is fixedly mounted, the ring 94 is sleeved on the rotating rod 6, and the ring 94 is arranged above the disc 95; the lifting motor 91 on the mounting plate 3 is started, and the output shaft of the lifting motor 91 rotates to drive the screw rod 92 to rotate, and the screw rod 92 rotates to drive the lifting plate 93 threadedly connected thereto to rise or fall, and the lifting plate 93 drives the ring 94 to rise or fall. When the ring 94 falls, the disc 95, the rotating rod 6 and the scraper 8 are pushed to fall vertically. When the ring 94 rises, the scraper 8 is pulled away from the inner wall of the evaporation box 1 by the restoring force of the spring 11, so that the height of the scraper 8 can be easily adjusted.

[0030] The diameter of the ring 94 is larger than the diameter of the rotating rod 6, and the diameter of the ring 94 is smaller than the diameter of the disk 95; the diameter of the ring 94 is larger than the diameter of the rotating rod 6, so that the ring 94 does not contact the rotating rod 6 after adjusting the position of the rotating rod 6, thereby reducing the pressure on the rotating rod 6 and the scraper 8 when the rotating rod 6 and the scraper 8 rotate. The diameter of the ring 94 is smaller than the diameter of the disk 95, which makes it easier for the ring 94 to drive and adjust the height of the disk 95, the rotating rod 6 and the scraper 8.

[0031] The evaporator box 1 is configured to have two sections, which are threadedly connected. A handle 10 is fixedly mounted at the bottom of the evaporator box 1 . By turning the handle 10 at the bottom, the evaporator box 1 can be divided into sections, which is convenient for maintenance and repair of the interior of the evaporator box 1 .

[0032] A controller is provided on the mounting plate 3 , and the controller is electrically connected to the rotating motor 4 and the lifting motor 91 respectively; the controller can realize automatic control of the device components.

[0033] Working principle:

[0034] 1. Waste liquid introduction and evaporation stage:

[0035] The waste liquid to be treated is introduced into the evaporation box 1 through a pipeline. The evaporation box 1 is used as a temporary storage container to temporarily store the waste liquid;

[0036] The heating component is started to heat the waste liquid in the evaporation box 1. As the temperature rises, the water in the waste liquid begins to evaporate, and the formed water vapor is discharged out of the device through the outlet pipe 2;

[0037] During the evaporation process, other components in the waste liquid gradually concentrate to form concentrates, which stay at the bottom of the evaporation box 1;

[0038] 2. Stirring and accelerated evaporation stage:

[0039] Start the rotating motor 4 on the mounting plate 3, and the output shaft of the motor rotates to drive the cross plate 5, the rotating rod 6, the stirring rod 7 and the scraper 8 to rotate synchronously;

[0040] The stirring rod 7 continuously stirs the waste liquid during the rotation process, accelerating the mixing of the waste liquid and the hot air, thereby further improving the evaporation efficiency;

[0041] At the same time, the scraper bar 8 also produces a certain stirring effect on the waste liquid during the rotation process, further promoting the evaporation process;

[0042] 3. Inner wall concentrate scraping stage:

[0043] When the waste liquid evaporates to a certain extent, part of the concentrate will adhere to the inner wall of the evaporation box 1. At this time, the lifting motor 91 in the lifting member 9 is started;

[0044] The lifting motor 91 drives the screw rod 92 to rotate, and the screw rod 92 is connected with the lifting plate 93 by a thread, so that the lifting plate 93 drives the ring 94 to descend; when the ring 94 descends, it pushes the disc 95, the rotating rod 6, the cross plate 5 and the scraper 8 to pull the spring 11 to descend vertically as a whole;

[0045] Since the evaporation box 1 is designed to be in the shape of an inverted truncated cone, and the inclination of the scraper strip 8 matches the inclination of the inner wall of the evaporation box 1, the scraper strip 8 can fit the inner wall of the evaporation box 1 during the descending process;

[0046] After lamination, the rotating motor 4 is started again, and the scraper 8 is driven by the motor to rotate along the inner wall of the evaporation box 1 to scrape off the attached concentrate;

[0047] After scraping is completed, the lifting motor 91 is restarted to make the lifting plate 93 and the ring 94 rise, and the scraper strip 8 is moved away from the inner wall of the evaporator box 1 again by the restoring force of the spring 11;

[0048] 4. Concentrate collection and device reset stage:

[0049] The concentrate scraped off from the scraper bar 8 automatically separates from the scraper bar 8 under the action of sewage stirring and falls into the bottom of the evaporation box 1 for collection;

[0050] After the device is reset, the stirring rod 7 and the scraper 8 continue to rotate to stir the waste liquid to ensure the continuation of the evaporation process;

[0051] 5. Maintenance and overhaul stage:

[0052] When it is necessary to maintain or overhaul the interior of the evaporator box 1, the evaporator box 1 can be divided into two sections, upper and lower, by rotating the handle 10 at the bottom of the evaporator box 1, so as to facilitate operations such as cleaning and maintenance.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
