Description

Technical Field

[0001] The utility model belongs to the technical field of titanium dioxide production devices, in particular to an iron removal device for titanium dioxide production using a sulfuric acid process. Background Art

[0002] During the production of titanium dioxide by sulfuric acid method, impurities mainly composed of iron need to be removed to obtain pure titanium dioxide, so the whole production process needs to be iron-removed to achieve the purpose of purifying titanium dioxide. During the production process, the import and export of equipment involving titanium dioxide slurry will be equipped with iron removal devices to absorb visible iron impurities.

[0003] like Figure 8 , Fig. 9 As shown, it is an iron removal device for titanium dioxide slurry in the prior art, which is arranged at the inlet and outlet of the relevant equipment, including a material trough 1 and a magnetic bar 4 installed in the material trough. An upper fixed plate 8 and a lower fixed plate 9 parallel to each other are fixedly arranged in the material trough, and the upper fixed plate and the lower fixed plate are provided with corresponding sockets, and the magnetic bar is vertically inserted into the corresponding socket. When it is necessary to clean the iron impurities on the magnetic bar, the corresponding magnetic bar needs to be pulled out, but in the process of pulling out the magnetic bar, the socket will scrape off the impurities adsorbed on the magnetic bar and drop them into the material trough, causing secondary pollution to the material trough.

[0004] Therefore, there is an urgent need for an iron removal device for producing titanium dioxide by the sulfuric acid process to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the existing technical problems and provide an iron removal device for producing titanium dioxide by sulfuric acid process.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented according to the following technical scheme:

[0007] A deironing device for producing titanium dioxide by sulfuric acid process, comprising a trough and a deironing assembly arranged in the trough; the trough is a rectangular parallelepiped, and its rear end face and upper end face are open;

[0008] The rear side of the left inner wall and the rear side of the right inner wall of the material trough are symmetrically provided with rear clamping grooves;

[0009] The iron removal assembly includes a plurality of magnetic bars, a front fixing plate, a rear fixing plate, and a connecting plate; the plurality of magnetic bars are arranged in sequence from left to right; the front fixing plate and the rear fixing plate are both provided with a plurality of jacks from left to right; the front ends of the plurality of magnetic bars all penetrate the jacks on the front fixing plate, and the rear ends of the plurality of magnetic bars all penetrate the jacks on the rear fixing plate;

[0010] The left and right sides of the rear fixing plate are respectively inserted into the rear clamping grooves on the left and right sides, and the front end of the magnetic rod contacts the bottom of the material trough.

[0011] The magnetic bars involved in the utility model are prior art, and those skilled in the art can select magnetic bars of appropriate sizes for iron removal according to actual use requirements, and no further restrictions are imposed on their models herein.

[0012] When the utility model is in use, the magnetic bar, the front fixing plate, the rear fixing plate and the connecting plate form an integral iron removal assembly. If iron removal is required during use, the entire assembly can be directly taken out from the material trough, and then the corresponding magnetic bar can be cleaned. Therefore, the cleaned iron impurities will not fall into the material trough, avoiding contamination of the material trough. The setting of the connecting plate makes the structure of the entire iron removal assembly more stable, enhances its strength, and avoids the impact of the iron removal assembly on the slurry passing through the material trough to cause deformation.

[0013] Preferably, the front end of the material trough is open, so that the titanium dioxide slurry passing through the material trough can be directly discharged from the front end of the material trough and enter the next process.

[0014] Preferably, the front end surface of the trough is provided with an openable door. The arrangement of the openable door is convenient for choosing to open or close the door according to actual use requirements.

[0015] Preferably, front card slots are symmetrically arranged on the front sides of the left inner wall and the right inner wall of the material trough; and the left and right sides of the front fixing plate are respectively inserted into the front card slots on the left and right sides.

[0016] The setting of the front card slot can make the installation of the entire iron removal assembly more stable. The front card slot can be added when the flow rate of titanium dioxide slurry is large and the impact force of the outflow is strong.

[0017] Preferably, the installation height of the front card slot is lower than the installation height of the rear card slot.

[0018] The difference in installation height between the front card slot and the rear card slot enables the magnetic bar to be set obliquely in the material trough, increasing the contact area between the magnetic bar and the titanium dioxide slurry, so that it can better remove iron.

[0019] Preferably, a front clamping ring is detachably fixedly mounted on the magnetic bar located at the front side of the front fixing plate, and a rear clamping ring is detachably fixedly mounted on the magnetic bar located at the rear side of the rear fixing plate.

[0020] The setting of the front clamp ring and the rear clamp ring allows the magnetic bar to be detachably installed on the support frame formed by the front fixing plate, the rear fixing plate and the connecting plate, and magnetic bars of different lengths can be selected according to the actual iron removal needs. Specifically, when a longer magnetic bar is selected, the angle between the magnetic bar and the bottom of the trough is smaller; when a shorter magnetic bar is selected, the angle between the magnetic bar and the bottom of the trough is larger. The magnetic bar of appropriate length can be selected for iron removal according to the actual use needs, which is more flexible to use.

[0021] Preferably, the front clamping ring and the rear clamping ring are clamps or elastic rubber rings.

[0022] The clamp can be a detachable clamp commonly used in the prior art, and can be a worm gear clamp, a T-type clamp, a U-type clamp, etc., which can be selected according to actual use requirements. The elastic rubber ring can be a rubber rubber ring, a silicone rubber ring, etc. The elastic rubber ring can be tightly clamped on the magnetic rod to prevent the magnetic rod from moving.

[0023] Components not limited in the present invention all adopt conventional means in the field. Those skilled in the art can select their models and installation methods according to actual usage requirements and clearly understand how to install and control them, which will not be described in detail here.

[0024] The utility model achieves the following beneficial effects:

[0025] The utility model has a simple structure and is easy to operate; the magnetic rod of the utility model is easy to disassemble, and iron impurities will not fall into the material trough during the disassembly process, thereby preventing the material trough from being contaminated.
