Description

Technical Field

[0001] The utility model belongs to the technical field of heavy ash preparation, and in particular relates to a soda ash heavy ash crystallization device. Background Art

[0002] In the production of soda ash, heavy soda ash, especially low-salt high-quality heavy soda ash, is becoming more and more popular among users due to its excellent properties such as large particle density, small stacking angle, low impurity content and non-agglomeration. So far, the production of heavy soda ash using light soda ash as raw material in China is usually carried out using liquid phase hydration method and solid phase hydration method.

[0003] In the solid-phase hydration method, crystals are generated through a hydrator. During the production process, process water is added to powdered solid light soda ash, and a chemical reaction occurs under sufficient stirring and mixing conditions. However, during the crystallization process, crystals easily adhere to the inner wall of the container to form alkali scars. As the crystals accumulate, they need to be cleaned frequently. Stirring alone cannot effectively inhibit the adhesion of crystals. For this reason, the inventors proposed a soda ash heavy ash crystallization device. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the accumulation of crystals needs to be frequently cleaned up later. Aiming at the deficiencies of the prior art, a soda ash heavy ash crystallization device is provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] It includes a barrel body and a box body, the barrel body is fixedly installed inside the box body, a barrel cover is installed on the top of the barrel body, a reciprocating screw is fixedly installed on the inner bottom wall of the barrel cover, a cleaning component is rotatably arranged on the surface of the reciprocating screw, the cleaning component is used to utilize the rotation of the liquid and the friction with the inner wall of the barrel body to clean the barrel body, and a stirring component is arranged on the inner bottom wall of the barrel body, the stirring component is used to drive the liquid inside the barrel body to rotate.

[0007] Furthermore, the cleaning assembly includes a lifting ring slidably arranged on the outer surface of the reciprocating screw, a wire groove slider is fixedly installed on the inner wall of the lifting ring, the wire groove slider is slidably connected to the wire groove on the surface of the reciprocating screw, and a water-driven wheel piece is fixedly installed on the surface of the lifting ring.

[0008] Furthermore, a cleaning plate is rotatably provided at one end of the water-driven wheel piece, a spring piece is installed on one side of the cleaning plate, and one end of the spring piece abuts against the surface of the water-driven wheel piece.

[0009] Furthermore, a distribution ring is fixedly installed on one end of the surface of the water-driven wheel blade, and an elastic scraper is provided on the surface of the distribution ring.

[0010] Furthermore, the stirring assembly includes an impeller rotatably arranged on the bottom wall of the barrel body, and a driving motor is fixedly installed on one side of the box body, and the driving motor is used to drive the impeller to rotate.

[0011] Furthermore, the surface of the barrel body is provided with heat dissipation fins, a sealing bottom plate is fixedly installed inside the box body, a water inlet pipe is provided on the top of the box body, and a water outlet pipe is provided on the bottom of the box body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The stirring component drives the liquid inside the barrel to rotate, and the cleaning component is driven to rotate when the liquid rotates. While the cleaning component rotates, it reciprocates up and down along the reciprocating screw rod, so that the cleaning component rubs against the inner wall of the barrel, making it difficult for crystals to adhere to the inner wall of the container during the crystallization process, delaying the accumulation of crystals and reducing the frequency of cleaning. The friction cleaning of the stirring and cleaning components can better inhibit the adhesion of crystals.

[0014] 2. The device uses the driving force of the stirring component to borrow the flow of liquid to enable the cleaning component to complete the up and down reciprocating movement and rotation cleaning, while maintaining a relatively simple structure and having a relatively comprehensive cleaning effect, and the cleaning effect is better.

[0015] 3. When the cleaning plate rotates, one side contacts the inner wall of the barrel. Under the push of the inner wall, the cleaning plate deflects with one side of the water drive wheel as the center, causing one end of the spring to slide along the surface of the water drive wheel and deform. Under the elastic force of the spring, one side of the cleaning plate is always in contact with the inner wall of the barrel, thereby ensuring the cleaning effect of the cleaning plate.

The surface of the reciprocating screw 12 is provided with two wire grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. A cleaning component 30 is rotatably arranged on the surface of the reciprocating screw 12. The cleaning component 30 reciprocates up and down along the reciprocating screw 12 while rotating. The cleaning component 30 is used to utilize the rotation of the liquid to rub against the inner wall of the barrel body 10 to clean The barrel body 10 is provided with a stirring assembly 40 on the inner bottom wall thereof so that the crystals are not easily adhered to the inner wall of the container during the crystallization process, the accumulation of the crystals is delayed, and the frequency of cleaning is reduced. The inner bottom wall of the barrel body 10 is provided with a stirring assembly 40, and the stirring assembly 40 is used to drive the liquid inside the barrel body 10 to rotate.

A feeding pipe 13 is provided on the top of the barrel cover 11, and a discharge pipe 14 is provided on the side of the barrel body 10. The liquid enters the barrel body 10 through the feeding pipe 13 to react and generate crystals to form a mixed liquid which is discharged from the discharge pipe 14 to the device.

[0025] See also Figure 3-5The cleaning assembly 30 includes a lifting ring 31 slidably arranged on the outer surface of the reciprocating screw rod 12, a wire groove slider 32 is fixedly installed on the inner wall of the lifting ring 31, and the wire groove slider 32 is slidably connected to the wire groove on the surface of the reciprocating screw rod 12, and a water drive wheel piece 33 is fixedly installed on the surface of the lifting ring 31. When the cleaning assembly 30 is cleaning, the rotation of the liquid drives the water drive wheel piece 33 to rotate, and the rotation of the water drive wheel piece 33 drives the lifting ring 31 to rotate, and a cleaning plate 34 is rotatably arranged on one end of the water drive wheel piece 33, and the lifting ring 31 reciprocates along the wire groove through the wire groove slider 32, so that the cleaning plate 34 cleans different areas at different heights of the barrel body 10, and the driving force of the stirring assembly 40 borrows the flow of liquid to enable the cleaning assembly 30 to complete the up and down reciprocating movement and rotation cleaning, while maintaining a relatively simple structure and having a relatively comprehensive cleaning function. To achieve a good cleaning effect, a spring sheet 35 is installed on one side of the cleaning plate 34, one end of the spring sheet 35 abuts against the surface of the water drive wheel sheet 33, and one side of the cleaning plate 34 contacts the inner wall of the barrel body 10 when the cleaning plate 34 rotates. Under the push of the inner wall, the cleaning plate 34 is deflected with one side of the water drive wheel sheet 33 as the center, so that one end of the spring sheet 35 slides along the surface of the water drive wheel sheet 33 and deforms. Under the elastic force of the spring sheet 35, one side of the cleaning plate 34 is always in contact with the inner wall of the barrel body 10, thereby ensuring the cleaning effect of the cleaning plate 34, a first shaft sleeve 36 is provided on one side of the water drive wheel sheet 33, and a second shaft sleeve 37 is provided on one side of the cleaning plate 34.

[0026] See also Figure 5 The stirring assembly 40 includes an impeller 41 rotatably arranged on the inner bottom wall of the barrel body 10, a driving motor 42 is fixedly installed on one side of the box body 20, the driving motor 42 is used to drive the impeller 41 to rotate, a driving wheel 43 is fixedly installed on the output end of the driving motor 42, the axis of the impeller 41 passes through the bottom of the barrel body 10 and is fixedly installed with a rotating wheel 44, and a belt 45 is arranged on the surface of the driving wheel 43 and the rotating wheel 44.

[0027] See also Figure 2 The surface of the barrel body 10 is provided with heat dissipation fins 21, and a sealing bottom plate 22 is fixedly installed inside the box body 20. A water inlet pipe 23 is provided on the top of the box body 20, and a water outlet pipe 24 is provided at the bottom of the box body 20. The coolant enters the box body 20 through the water inlet pipe 23, takes away the heat in the barrel body 10 through the heat dissipation fins 21, and is discharged through the water outlet pipe 24. The coolant circulates between the barrel body 10 and the box body 20 to take away the heat released during crystal formation, so that the liquid inside the barrel body 10 is maintained at a certain temperature, avoiding incomplete reaction due to temperature influence, and improving the crystal formation efficiency.

[0028] Beneficial effects:

[0029] 1. The stirring component 40 drives the liquid inside the barrel body 10 to rotate, and the cleaning component 30 is driven to rotate when the liquid rotates. While the cleaning component 30 rotates, it reciprocates up and down along the reciprocating screw rod 12, so that the cleaning component 30 rubs against the inner wall of the barrel body 10, making it difficult for crystals to adhere to the inner wall of the container during the crystallization process, greatly delaying the accumulation of crystals and reducing the frequency of cleaning. The adhesion of crystals can be better suppressed by stirring and cleaning with the friction of the cleaning component.

[0030] 2. When the cleaning component 30 is cleaning, the rotation of the liquid drives the water-driven wheel piece 33 to rotate, and the rotation of the water-driven wheel piece 33 drives the lifting ring 31 to rotate. The lifting ring 31 reciprocates along the wire groove through the wire groove slider 32, so that the cleaning plate 34 cleans different areas at different heights of the barrel body 10. The device uses the driving force of the stirring component 40 to borrow the flow of liquid to enable the cleaning component 30 to complete the up and down reciprocating movement and rotation cleaning, while maintaining a relatively simple structure. It has a more comprehensive cleaning effect, and the cleaning effect is better.

[0031] 3. When the cleaning plate 34 rotates, one side contacts the inner wall of the barrel body 10. Under the push of the inner wall, the cleaning plate 34 deflects around one side of the water drive wheel piece 33, causing one end of the spring piece 35 to slide along the surface of the water drive wheel piece 33 and deform. Under the elastic force of the spring piece 35, one side of the cleaning plate 34 is always in contact with the inner wall of the barrel body 10, thereby ensuring the cleaning effect of the cleaning plate 34.

[0032] Embodiment 2: Embodiment 2 is a further improvement made on the basis of Embodiment 1, see Figure 5 The present embodiment is a soda ash heavy ash crystallization device. Different from the embodiment 1, the present embodiment does not include the cleaning plate 34 and the spring piece 35. A distribution ring 39 is fixedly installed on one end of the surface of the water drive wheel piece 33. The distribution ring 39 is a closed circular ring. The inner wall of the circular ring is connected to all the water drive wheel pieces 33. An elastic scraper 391 is arranged on the surface of the distribution ring 39. The material of the elastic scraper 391 is rubber.

[0033] Beneficial effect: By setting the distribution ring 39, the elastic scraper 391 can be set in any number without being affected by the number of water-driven wheel blades 33. The number of elastic scrapers 391 can be increased to improve the cleaning effect while the number of water-driven wheel blades 33 is not increased, thereby avoiding the water-driven wheel blades 33 being too dense to reduce the passability of the water flow to the cleaning component 30.
