[0002] High-salinity wastewater mainly originates from chemical plants and the extraction and processing of oil and natural gas. This wastewater contains various substances, including salt, oil, organic heavy metals, and radioactive materials. Evaporation and crystallization are necessary to treat high-salinity wastewater. During operation, salt crystals from the high-salinity wastewater gradually adhere to the inner wall of the tank or the scraper ring, creating gaps between the scraper ring and the tank wall.

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The evaporation and crystallization equipment of this embodiment includes a scraper assembly 3, a tank 2, and a drive assembly 1. The tank 2 has a cavity 21. The drive assembly 1 is mounted on the tank 2, and its output end extends into the cavity 21 and is connected to the scraper assembly 3. The scraper assembly 3 includes a connecting component 31, an elastic element 32, and a scraper 33. The connecting component 31 is mounted on the output end of the drive assembly 1 and has a sliding groove 3111 for mounting the scraper 33. The elastic element 32 is mounted on the connecting component 31 and connected to the scraper 33, so that the end of the scraper 33 away from the elastic element 32 extends out of the sliding groove 3111 and abuts against the wall of the cavity 21.

[0030] Rotate the adjusting component, which is threaded into the tank body 2, and rotate the adjusting component to move the end of the adjusting component that extends into the cavity 21 away from or towards the scraper 33.

[0031] Specifically, such as Figures 1 to 4 As shown, the tank body 2 extends in the vertical direction, the scraper assembly 3 is disposed in the cavity 21, and the output end of the drive assembly 1 is connected to the scraper assembly 3 to drive the scraper assembly 3 to rotate in the cavity 21. The scraper 33 of the scraper assembly 3 contacts the inner wall surface of the cavity 21 to remove the crystals on the inner wall surface.

[0032] The connecting component 31 is connected to the output end of the driving component. The connecting component 31 is equipped with an elastic element 32 and a scraper 33. A sliding groove 3111 is provided on the connecting component 31 to mount the scraper 33. The scraper 33 moves within the sliding groove 3111 to approach or move away from the inner wall of the cavity 21. The elastic element 32 is located on the connecting component 31, with one end of the elastic element 32 away from the inner wall of the cavity 21. The elastic element 32 applies a spring force to the scraper 33 to bring it into contact with the inner wall of the cavity 21. This removes crystals from the inner wall of the cavity 21 within the tank 2. A rotating adjusting component is threaded into the tank 2. Rotating the adjusting component moves the end of the rotating adjusting component that extends into the cavity 21 in a direction away from or towards the scraper 33.

[0033] The rotating adjustment component is rotated so that it extends into the cavity 21, and moves in a direction away from or towards the scraper 33. For example, the rotating adjustment component moves away from the scraper 33 so that the scraper 33 can scrape away the crystals on the inner wall surface. Conversely, the rotating adjustment component moves towards the scraper 33, causing the scraper 33 to interfere with the rotating adjustment component during rotation, resulting in the rotating adjustment component repeatedly moving or vibrating in both directions. This causes the scraper 33 to impact the inner wall surface, removing the crystals. Simultaneously, during movement and vibration, the crystals on the scraper 33 are removed and prevented from remaining on the scraper 33.

[0034] The evaporation crystallization equipment of this utility model is equipped with an elastic element 32 to allow the scraper 33 to abut against the inner wall surface of the cavity 21 of the tank 2. At the same time, a rotation adjustment component is provided. After the evaporation crystallization equipment has been running for a period of time, the rotation adjustment component moves towards the scraper 33 to interfere with the rotation of the scraper 33, so as to facilitate the cleaning of the inner wall surface of the tank 2, avoid crystallization on the inner wall surface of the cavity 21 of the tank 2, and improve the stability of the equipment.

[0035] In some embodiments, the rotating adjustment component 4 includes a connecting rod 41 and a handle 42 connected to each other. The handle 42 is disposed outside the tank body 2. The connecting rod 41 is threadedly engaged with the tank body 2. One end of the connecting rod 41 extends into the cavity 21. Rotating the handle 42 causes the end of the connecting rod 41 extending into the cavity 21 to move away from or towards the scraper 33.

[0036] Specifically, such as Figures 1 to 4As shown, one end of the connecting rod 41 is threaded into the tank body 2, so that when the handle 42 rotates the connecting rod 41, the end of the connecting rod 41 that extends into the cavity 21 moves toward or away from the scraper 33, so that the scraper 33 impacts the connecting rod 41 during operation to remove the crystals on the scraper 33. At the same time, after impacting the connecting rod 41, the scraper 33 moves back and forth in the sliding groove 3111 to remove the crystals on the inner wall of the cavity 21. By providing the handle 42, it is easy to rotate the connecting rod 41, thus improving the convenience of rotating the connecting rod 41.

[0037] In some embodiments, the evaporation crystallization apparatus further includes an abutment block 43, which is rotatably connected to one end of the connecting rod 41 that extends into the cavity 21. The tank body 2 has a groove into which the abutment block 43 can extend or extend. The abutment block 43 extends into the groove to prevent the scraper 33 from contacting it during operation. The abutment block 43 extends out of the groove to allow the scraper 33 to contact it during operation, thus impacting the abutment block 43. The rotatable connection between the abutment block 43 and the end of the connecting rod 41 extending into the cavity 21 allows one end of the abutment block 43 to smoothly extend into the cavity 21, while the other end does not extend into the cavity 21, causing the abutment block 43 to tilt relative to the scraper 33. This causes the scraper 33 to gradually move away from the abutment block 43 when impacting it, reducing the abrasion caused by the impact between the abutment block 43 and the scraper 33.

[0038] In other words, the interior of tank 2 is designed with a recess. The position and shape of this recess are specifically designed to mate with the abutment block 43. The abutment block 43 can extend out of the recess as needed. When the abutment block 43 extends into the recess, the connecting rod 41 stops rotating, thus fixing the position of the abutment block 43 and preventing it from contacting the scraper 33 operating inside tank 2. This design avoids equipment damage or malfunction caused by collisions between the scraper 33 and the abutment block 43 during scraping operation. When the scraper 33 needs to perform some form of impact or cleaning on the abutment block 43, the abutment block 43 can be operated to extend out of the recess. In this way, when the scraper 33 operates, it will contact the extended abutment block 43, thereby producing the required impact effect to clean the crystals or other impurities accumulated on the inner wall of cavity 21.

[0039] The evaporation crystallization equipment of this utility model, through the cooperation between the abutment block 43 and the groove, and the rotatable connection between the abutment block 43 and the connecting rod 41, realizes flexible control over the contact between the scraper 33 and the abutment block 43. This not only protects the normal operation of the equipment, but also meets the needs of cleaning crystallization.

[0040] In some embodiments, the abutment block 43 includes a slider 431 and an abutment block body 432. One end of the abutment block body 432 is rotatably mounted in a groove. The abutment block body 432 is provided with a slot 4322 for rotatably mounting the slider 431, and the connecting rod 41 is rotatably connected to the slider 431.

[0041] Specifically, such as Figures 1 to 4 As shown, a slot 4322 is designed on the abutment block body 432. The shape and position of the slot 4322 are designed for mounting the slider 431. The design of the slot 4322 allows the slider 431 to be rotatably mounted on the abutment block body 432, so that when the connecting rod 41 rotates to move closer to or away from the scraper 33, the slider 431 can also swing or rotate within a certain range to make the abutment block body 432 rotate, thereby improving the smoothness and stability of the abutment block 43 in use.

[0042] In some embodiments, the end face of the contact block body 432 facing the scraper 33 is an arc-shaped surface 4321. This reduces friction and wear when the scraper 33 and the contact block body 432 come into contact. When the scraper 33 impacts the contact block body, the arc-shaped surface 4321 can guide the scraper 33 through more smoothly, reducing unnecessary resistance and loss. At the same time, the smooth transition of the arc-shaped surface 4321 helps to reduce the bumps or vibrations that the scraper 33 may experience when passing through the contact block 43, which helps to improve the operational stability and reliability of the entire evaporation crystallization equipment.

[0043] Furthermore, there are multiple rotating adjustment components, which are spaced apart circumferentially on the tank body 2.

[0044] In some embodiments, the connecting component 31 includes a connector 311 and a mounting housing 312. The mounting housing 312 is disposed on the connector 311. A sliding groove 3111 is disposed at one end of the connector 311 adjacent to the inner wall of the tank 2. One end of the elastic member 32 is installed in the mounting housing 312, and the other end of the elastic member 32 is connected to the scraper 33.

[0045] The mounting housing 312 serves to house and protect the elastic element 32. It also guides or supports the elastic element 32 to ensure its stable operation, thereby allowing the scraper 33 to move smoothly within the sliding groove 3111. One end of the elastic element 32 is installed inside the mounting housing 312, and the other end is connected to the scraper 33. The elastic element 32 provides a continuous thrust or pull force, enabling the scraper 33 to move closely against the inner wall of the tank 2. When the scraper 33 encounters resistance or obstacles, the elastic element 32 absorbs the impact force and stores the impact energy as elastic potential energy, allowing the scraper 33 to subsequently impact the inner wall of the cavity 21.

[0046] In some embodiments, the scraper 33 includes a limiting section 331 and an abutting section 332. The limiting section 331 is disposed in the sliding groove 3111 and connected to the elastic member 32. One end of the abutting section 332 is connected to the limiting section 331, and the other end of the abutting section 332 abuts against the inner wall surface of the tank 2. The cross-sectional area of ​​the limiting section 331 in the direction orthogonal to the height of the tank 2 is greater than the cross-sectional area of ​​the outlet of the sliding groove 3111.

[0047] Specifically, such as Figures 1 to 4 As shown, the cross-sectional area of ​​the limiting section 331 in the plane orthogonal to the vertical direction is greater than that of the abutting section 332 in the same plane. Simultaneously, the cross-sectional area of ​​the limiting section 331 in the plane orthogonal to the vertical direction is greater than that of the abutting section 332 at the outlet of the sliding groove 3111 in the same plane. Conversely, the cross-sectional area of ​​the abutting section 332 in the plane orthogonal to the vertical direction is smaller than that at the outlet of the sliding groove 3111 in the same plane. This allows the limiting section 331 to move within the sliding groove 3111, causing the abutting section 332 to extend or retract into the outlet of the sliding groove 3111. This ensures that the limiting section 331 will not detach from the sliding groove 3111 during movement, while the abutting section 332 will extend or retract into the outlet of the sliding groove 3111 as needed, thereby contacting or separating from the inner wall of the tank 2.

[0048] The abutment section 332 contacts the inner wall surface of the outlet of the sliding groove 3111. It is understood that the contact between the abutment section 332 and the inner wall surface of the outlet of the sliding groove 3111 ensures that crystals on the outer side of the abutment section 332 are removed when entering or exiting the outlet of the sliding groove 3111, as the outlet of the sliding groove 3111 is in close contact with the abutment section 332, thus preventing crystal accumulation on the scraper 33. In other words, the close contact between the abutment section 332 and the inner wall of the tank 2 effectively scrapes away material or crystals adhering to the scraper 33. The scraper 33 can move in close contact with the inner wall at the opening of the sliding groove 3111, providing stability to prevent lateral displacement, which makes the equipment easier to clean and maintain.

[0049] In some embodiments, the evaporation crystallization apparatus further includes a heating element 5 and a feed pipe 6, which are disposed at the top of the tank 2, and the feed pipe 6 is connected to the cavity 21. The heating element 5 may be an electric heating rod.

[0050] High-salinity wastewater enters tank 2 through feed pipe 6. An electric heating rod fixedly installed on the top of tank 2 starts working to heat the high-salinity wastewater inside the tank. At the same time, a temperature sensor 7 can be installed on tank 2 to monitor the temperature inside the tank in real time and transmit the temperature signal to the temperature controller. The temperature controller compares the received actual temperature with the preset temperature value. When the actual temperature is lower than the set temperature, it sends a signal to the electric heating rod to turn on the power and heat the wastewater inside the tank. As heat is continuously input, the water in the wastewater gradually evaporates, and the salt begins to crystallize due to the increased concentration, realizing the evaporation and crystallization operation of high-salinity wastewater.

[0051] Subsequently, the drive unit is activated, and the output section of the drive unit drives the connecting part 31 connected to it to rotate. The scraper 33 on the connecting part 31 rotates with the connecting part 31 and makes a circular motion, thereby stirring the high-salt wastewater in the cavity 21 of the tank 2. At the same time, the elastic elements 32 in the mounting housing 312 located on the upper and lower sides of the connecting part 31 push the scraper 33 to move towards the inner wall of the cavity 21, thereby allowing the scraper 33 to extend and fit against the inner wall of the tank 2, thereby scraping off the deposits on the tank wall.

[0052] Periodically turn the hand-tightening handle 42, and one end of the connecting rod 41 is screwed into the cavity 21 of the tank body 2. The connecting rod 41 pushes one end of the abutment block 43 out of the groove. During the rotation of the scraper 33, when one end of the scraper 33 contacts the end of the abutment block 43 protruding from the groove, the scraper 33 will be pushed back into the sliding groove 3111. The salt crystals attached to both sides of the scraper 33 will fit against the inner wall surface on both sides of the opening of the sliding groove 3111 when it retracts into the inner cavity of the sliding groove 3111, thereby preventing the salt crystals from adhering to the two sides of the scraper 33 and affecting the scraping effect on the inside of the tank body 2. When the scraper 33 passes the abutment block 43, the scraper 33 will be automatically pushed out of the inner cavity of the sliding groove 3111 by the push of the elastic element 32.
