Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide production technology, specifically to a titanium dioxide crystallization device that avoids valve blockage. Background Technology

[0002] Titanium dioxide is an important inorganic chemical pigment, whose main component is titanium dioxide. There are two production processes for titanium dioxide: the sulfuric acid process and the chloride process. It has important applications in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. It has two structures: rutile and anatase. Rutile crystals have a dense and stable structure with low optical activity.

[0003] The patent CN214344538U discloses a titanium dioxide concentration and crystallization device. This patent discloses a technical solution for liquid level control, which solves the problem that existing titanium dioxide concentration and crystallization devices all use vacuum crystallization tanks for crystallization. Vacuum crystallization tanks generally use continuous crystallization and then discharge the crystals through an overflow port. At that time, it was difficult to connect to the liquid level in the vacuum crystallization tank in real time during use, which caused the titanium liquid to easily overflow from the overflow port, resulting in the waste of raw materials.

[0004] When in use, the device controls the liquid level inside the vacuum crystallizer through a liquid level sensor and a viewing window. However, when discharging the material after crystallization, the control valve is easily jammed, which can clog the discharge pipe and reduce the discharge efficiency. Therefore, a titanium dioxide crystallization device that avoids valve clogging is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4This embodiment of a titanium dioxide crystallization device for preventing valve blockage includes a titanium dioxide crystallization device 1 and a collection tank 2, a discharge pipe 4 and a control valve 5 disposed on the titanium dioxide crystallization device 1. A connecting plate 3 is fixedly fitted on the outer peripheral wall of the collection tank 2, and a striking component for striking the discharge pipe 4 is provided on the connecting plate 3.

[0027] The striking assembly includes two mounting plates 6, both of which are placed at the bottom of the connecting plate 3. An electric push rod 22 is fixedly mounted on the opposite side of each of the two mounting plates 6. A linkage plate 19 is fixedly connected to the output end of each of the two electric push rods 22. Two contact plates 18 are fixedly connected to the opposite side of each of the two linkage plates 19. A limit groove 20 is formed on the side of each of the two mounting plates 6 near the linkage plate 19. A limit plate 21 with one end extending into the limit groove 20 is fixedly connected to the side of each of the two linkage plates 19 away from the contact plate 18.

[0028] Among them, the mounting plate 6 and the limiting plate 21 are both L-shaped plates, the contact plate 18 is a T-shaped plate, the limiting plate 21 and the limiting groove 20 are slidably connected, and the control valve 5 is located between the four contact plates 18.

[0029] Specifically, after the mounting plate 6 and the connecting plate 3 are connected, the electric push rod 22 is activated. The output end of the electric push rod 22 drives the linkage plate 19 to move, so that the contact plate 18 and the discharge pipe 4 are in contact, and the discharge pipe 4 is struck to avoid crystallization from jamming the control valve 5 as much as possible. The linkage plate 19 is supported by the sliding connection between the limiting plate 21 and the limiting groove 20, thereby improving the stability of the linkage plate 19.

[0030] It should be noted that the titanium dioxide crystallization device 1 and the electric push rod 22 are both conventional devices known to the public in the prior art. Their specific structure and working principle will not be described in detail in this article. Furthermore, when titanium dioxide is crystallized, the crystallization does not go through a pre-cooling method, but directly enters the vacuum crystallizer for crystallization.

[0031] Please see Figures 1 to 4 In this embodiment, the connecting plate 3 is provided with a limiting component for restricting the mounting plate 6. The limiting component includes a positioning plate 7. Two positioning plates 7 are placed on the top surfaces of the two mounting plates 6 respectively. Two mounting slots 9 are opened on the bottom surfaces of the two connecting plates 3. The two mounting plates 6 extend into the interior of the two mounting slots 9 respectively. Two positioning slots 24 are opened on the top surfaces of the connecting plate 3. The positioning plates 7 are located inside the positioning slots 24. A connecting rod 8 extending to the positioning plate 7 is fixedly connected to the top surfaces of the two mounting plates 6. Rubber rings 23 are fixedly fitted on the outer peripheral walls of the two positioning plates 7. The mounting slots 9 allow the rotating positioning plates 7 to pass through.

[0032] In this configuration, the two connecting rods 8 are rotatably connected to the two positioning plates 7 via bearings, the mounting plate 6 and the mounting groove 9 are slidably connected, the rubber ring 23 and the positioning groove 24 are in contact, and the mounting groove 9 and the positioning groove 24 are connected.

[0033] Specifically, during installation of mounting plate 6, positioning plate 7 and mounting plate 6 are in a parallel state. When mounting plate 6 is pushed, it passes through mounting groove 9 and is located on top of connecting plate 3. The sliding connection between mounting plate 6 and mounting groove 9 supports mounting plate 6 and improves its stability. When positioning plate 7 is pushed, it rotates under the action of connecting rod 8, making positioning plate 7 and mounting plate 6 perpendicular. Mounting plate 6 is then reset, and positioning plate 7 is inserted into positioning groove 24 to restrict mounting plate 6. The fit between rubber ring 23 and positioning groove 24 supports positioning plate 7 and improves its stability.

[0034] Please see Figures 1 to 4 In this embodiment, the connecting plate 3 is provided with a fixing assembly for fixing the mounting plate 6. The fixing assembly includes two fixing plates 11, both of which are fixedly connected to the bottom surface of the connecting plate 3. Each of the two fixing plates 11 has a drive rod 10 that passes through the fixing plate 11 at one end, which is rotatably connected to the opposite side of the two fixing plates 11 via a bearing. Each of the two drive rods 10 has a screw 14 that extends into the drive rod 10 at one end, which is movably connected to the opposite side of the two screws 14. Each of the two movable plates 15 has a moving plate 15 that is fixedly connected to the opposite side of the two movable plates 15. Each of the two mounting plates 6 has a fixing hole 17 on the side near the fixing plate 11, and the fixing rod 16 extends into the fixing hole 17. Each of the two fixing plates 11 has a support hole 12 on the opposite side of the two fixing plates 11. Each of the two movable plates 15 has a support rod 13 that passes through the support hole 12 at one end, which is fixedly connected to the bottom surface of the two movable plates 15.

[0035] Among them, the two movable plates 15 are respectively attached to the two mounting plates 6, the fixed rod 16 and the fixed hole 17 are fitted with clearance, the two drive rods 10 are respectively provided with threaded holes on their opposite sides, and the two screws 14 extend into the interior of the two threaded holes and are threadedly connected to them.

[0036] Specifically, the fixing rod 16 and the fixing hole 17 are located on the same center line. Rotating the drive rod 10 causes the drive rod 10 to rotate. Through the threaded connection between the drive rod 10 and the screw 14 and the clearance fit between the support rod 13 and the support hole 12, the screw 14 drives the moving plate 15 to move. The moving plate 15 and the mounting plate 6 are in contact. The fixing rod 16 is inserted into the inside of the fixing hole 17. Through the clearance fit between the fixing rod 16 and the fixing hole 17, the mounting plate 6 is fixed.

[0037] The working principle of the above embodiments is as follows:

[0038] When the mounting plate 6 is installed, the positioning plate 7 and the mounting plate 6 are in a parallel state. Pushing the mounting plate 6 causes it to pass through the mounting groove 9 and be positioned on top of the connecting plate 3. Pushing the positioning plate 7 causes it to rotate under the action of the connecting rod 8, making the positioning plate 7 and the mounting plate 6 perpendicular. The mounting plate 6 is then reset, and the positioning plate 7 is inserted into the positioning groove 24 to restrict the mounting plate 6. The drive rod 10 is rotated, and through the threaded connection between the drive rod 10 and the screw 14 and the clearance fit between the support rod 13 and the support hole 12, the screw 14 drives the moving plate 15 to move. The fixing rod 16 is inserted into the fixing hole 17, and through the clearance fit between the fixing rod 16 and the fixing hole 17, the mounting plate 6 is fixed. The electric push rod 22 is activated, which drives the linkage plate 19 to move, so that the contact plate 18 and the discharge pipe 4 are in contact, striking the discharge pipe 4 to avoid crystallization from jamming the control valve 5.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
