Description

Technical Field

[0001] The utility model belongs to the field of facilitating the maintenance of chamber vacuum during the absorption of metatitanic acid, and relates to a structure for facilitating the maintenance of chamber vacuum during the absorption of metatitanic acid. Background Art

[0002] Metatitanic acid is a white powder with a bulk density of 1.0 - 1.2 g / cm 3 , belonging to non-hazardous chemicals, insoluble in inorganic acids and alkalis (except freshly precipitated metatitanic acid) and insoluble in water. Metatitanic acid can also be used as a delustering agent for chemical fibers, a catalyst, and an adsorbent for uranium in seawater; when a fire occurs with metatitanic acid, it can be extinguished with water, sand, and various fire extinguishers; one method for preparing metatitanic acid is to react ilmenite with sulfuric acid by the sulfuric acid method to generate titanyl sulfate, which is then purified, frozen to remove ferrous sulfate, pressure-filtered, concentrated, and then the titanyl sulfate is hydrolyzed, followed by washing, filtering, and drying to obtain metatitanic acid; during the existing production process of metatitanic acid, after washing and filtering, the metatitanic acid blocks are separated from the slurry by means of vacuum pumping, but once the vacuum pumping stops, the metatitanic acid blocks will fall into the water. Therefore, in order to solve the above technical problems, the technical solution of this application is set up. Content of the Utility Model

[0003] The purpose of the utility model is to provide a structure for facilitating the maintenance of chamber vacuum during the absorption of metatitanic acid, which solves the above technical problems.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A structure for facilitating the maintenance of chamber vacuum during the absorption of metatitanic acid, including a vertically arranged storage tank.

The adsorption structure and the second vacuum extraction pipes are detachably connected through a locking structure. An auxiliary vacuum extraction structure is communicated with the upper part of one of the support pipes.

[0006] The working principle of the present utility model is as follows: The storage pool is internally used to store the metatitanic acid slurry to be sucked. Through the upper opening of the storage pool, the top of the storage pool is used to place the support frame. Between the support frames, a support cavity is connected. Both ends of the support cavity are connected to the support pipes. Both ends of the support pipes are respectively connected to the first vacuum extraction pipe, and the other end of the first vacuum extraction pipe is connected to a vacuum pump. Through the detachable connection between the upper ends of the support pipes and the first vacuum extraction pipe, it is convenient to remove the support pipes together with the support frames and the support cavity, and then remove the second vacuum extraction pipe together with the support cavity. Finally, it is convenient to remove the metatitanic acid blocks adsorbed on the adsorption blocks. By improving the support pipes, when the support pipes need to be removed, by closing the first on-off valve, the vacuum degree inside the vacuum cavity is maintained, and then the auxiliary vacuum extraction structure is started to work. During the working process of the auxiliary vacuum extraction structure, the adsorption structure can continue to maintain the vacuum state during the movement process, so as to facilitate the metatitanic acid blocks to continue to be adsorbed on the adsorption structure, avoiding the state where the inside of the support cavity cannot maintain the vacuum when the support pipes are separated from the first vacuum extraction pipe, and further avoiding the problem that the metatitanic acid blocks are separated from the adsorption structure.

[0007] Further: The lower ends of the support pipes are respectively clamped with the upper ends of the first vacuum extraction pipes, and the first on-off valve is located above the clamping position of the support pipes and the first vacuum extraction pipes.

[0008] Further: The adsorption structure includes an adsorption plate. A number of screening holes for the passage of water bodies are evenly distributed on the adsorption plate. The screening holes include a number of small holes that are horizontally and vertically connected. An adsorption net for adsorbing metatitanic acid blocks is covered and connected to the outer wall of the adsorption plate. The top of the adsorption plate is connected to the lower end of the locking structure.

[0009] Further: The locking structure includes a locking pipe. The lower end of the locking pipe is connected to the top of the adsorption plate by threads and is communicated with the screening holes on the adsorption plate. A buckle is connected to the upper end of the locking pipe. A ferrule is connected to the lower end of the second vacuum extraction pipe, and the ferrule and the buckle are connected by clamping.

[0010] Further: The auxiliary vacuum extraction structure includes a third vacuum extraction pipe. One end of the third vacuum extraction pipe is communicated with the upper part of one of the support pipes, and the other end of the third vacuum extraction pipe is communicated with a fourth vacuum extraction pipe.

[0011] Further: A second on-off valve is connected between the third vacuum extraction pipes. The second on-off valve is located on the side close to the fourth vacuum extraction pipe.

[0012] Further: Fixing ropes are respectively connected to the tops of both sides of the support frame. Hanging rings are connected to the upper ends of the fixing ropes, and the hanging rings are matched with the hooks of the gantry crane.

[0014] 1. A structure for facilitating the maintenance of the vacuum in the cavity during the process of sucking metatitanic acid. When it is necessary to remove the support tube, by closing the first opening and closing valve, the vacuum degree inside the vacuum cavity is maintained, and then the auxiliary vacuum pumping structure is started to work. During the working process of the auxiliary vacuum pumping structure, the state of continuous vacuum pumping is satisfied during the movement of the adsorption structure, so as to facilitate the continuous adsorption of the metatitanic acid block on the adsorption structure;

[0015] 2. In the present utility model, the auxiliary vacuum pumping structure is convenient to move along with the support tube.

[0022] The features and performance of the present invention will be further described in detail below in conjunction with the embodiments.

[0023] Embodiment 1

[0024] A structure for facilitating the maintenance of the cavity vacuum during the process of sucking metatitanic acid according to the present invention, as Figure 1 shown, includes a vertically arranged storage tank 1. A space for storing metatitanic acid slurry is provided between the inner walls of the storage tank 1 and the upper end is open. A horizontally arranged support frame 2 is provided at the top of the storage tank 1. A support cavity 3 is connected between the support frames 2. Both ends of the support cavity 3 are respectively communicated with a support pipe 4. The intake ends of the support pipes 4 are respectively communicated with a first on-off valve 5. The lower ends of the support pipes 4 are respectively communicated with the upper ends of the first evacuation pipes 6 and are detachably connected. A plurality of second evacuation pipes 7 are respectively communicated with the outer walls on both sides of the support cavity 3. An adsorption structure for adsorbing metatitanic acid blocks is provided at the lower end of the second evacuation pipe 7. The adsorption structure and the second evacuation pipe 7 are detachably connected through a locking structure. An auxiliary evacuation structure is communicated with the upper part of one of the support pipes 4.

[0025] The specific implementation of this embodiment is as follows: The storage pool is internally used to store the metatitanic acid slurry to be sucked. Through the upper opening of the storage pool, the top of the storage pool is used to place the support frame. The support cavities are connected between the support frames. Both ends of the support cavity are connected to the support pipes. Both ends of the support pipes are respectively connected to the first evacuated pipe, and the other end of the first evacuated pipe is connected to the vacuum pump. The upper ends of the support pipes and the first evacuated pipe are detachably connected, which facilitates the removal of the support pipes together with the support frames and the support cavities, and then facilitates the removal of the second evacuated pipe along with the support cavity. Finally, it is convenient to remove the metatitanic acid blocks adsorbed on the adsorption block.

[0026] In this application, by improving the support pipe, when it is necessary to remove the support pipe, by closing the first on-off valve, the vacuum degree inside the vacuum cavity is maintained. Then, the auxiliary vacuum pumping structure is started to work. During the working process of the auxiliary vacuum pumping structure, the adsorption structure can continue to maintain the vacuum pumping state during the movement process, which facilitates the continued adsorption of the metatitanic acid blocks on the adsorption structure, avoiding the state where the inside of the support cavity cannot maintain vacuum when the support pipe is detached from the first evacuated pipe, and further avoiding the problem that the metatitanic acid blocks are detached from the adsorption structure.

[0027] When the adsorption structure is detached from the storage pool along with the support cavity, then the auxiliary vacuum pumping structure is closed, so that the metatitanic acid blocks on the adsorption structure are detached, which is convenient for collecting the metatitanic acid blocks. Finally, by loosening the locking structure, it is convenient to clean the inside of the adsorption structure.

[0028] In this application, by improving the existing support pipe, a first on-off valve is provided at the air inlet end of the support pipe, and an auxiliary vacuum pumping structure is connected to the support pipe. When the support pipe is removed from the first evacuated pipe, the first on-off valve is closed and the auxiliary vacuum pumping structure is started at the same time. Preferably, the auxiliary vacuum pumping structure is convenient to move along with the support pipe, and the suction force generated by the auxiliary vacuum pumping structure only needs to keep the metatitanic acid blocks adsorbed on the adsorption structure, avoiding the need for the auxiliary vacuum pumping structure to generate a large suction force inside the first evacuated pipe.

[0029] Embodiment Two

[0030] A structure for facilitating the maintenance of the vacuum in the cavity during the process of sucking metatitanic acid according to the present utility model is as Figure 1 shown. The lower ends of the support pipes 4 are respectively clamped to the upper ends of the first evacuated pipes 6, and the first on-off valve 5 is located above the clamping position of the support pipes 4 and the first evacuated pipes 6.

[0031] The adsorption structure includes an adsorption plate 8. A plurality of screening holes 9 for the passage of the water body are evenly distributed on the adsorption plate 8. The screening holes 9 include a plurality of small holes that are horizontally and vertically connected. An adsorption net 10 for adsorbing metatitanic acid blocks is covered and connected to the outer wall of the adsorption plate 8. The top of the adsorption plate 8 is connected to the lower end of the locking structure.

[0032] The locking structure includes a locking tube 11, the lower end of the locking tube 11 is connected to the top of the adsorption plate 8 through a thread and is connected to the screening hole 9 on the adsorption plate 8, the upper end of the locking tube 11 is connected with a buckle 12, and the lower end of the second vacuum tube 7 is connected with a clamping sleeve 13, and the clamping sleeve 13 is connected to the buckle 12 by clamping.

[0033] The specific implementation method of this embodiment is: the lower end of the support tube is clamped with the first vacuum tube to facilitate the installation of the support tube on the first vacuum tube. When the adsorption structure completes the adsorption of the titanate block, the clamping connection between the support tube and the first vacuum tube is released, thereby facilitating the removal of the support tube from the first vacuum tube.

[0034] By setting a plurality of screening holes on the adsorption plate, the suction force generated by the first vacuum tube is transmitted to the screening holes, and the titanate powder inside the storage pool is adsorbed on the adsorption net. The pressure inside the screening hole is lower than the pressure on the outer wall, so that the titanate powder approaches the screening hole, and the titanate powder is isolated by the adsorption net, so that the titanate powder forms a block of titanate on the adsorption net, and then the water entering through the screening holes is temporarily stored in the support cavity, and the water is prevented from entering the first vacuum tube through the support cavity, and finally the water is prevented from entering the vacuum pump.

[0035] The lower end of the locking tube is connected to the adsorption plate through a thread and is connected to the screening hole, so that the generated suction force can be transmitted to the screening hole. At the same time, the buckle is installed or disassembled with the sleeve at the lower end of the second vacuum tube, which makes it easy to clean the adsorption plate after disassembly.

[0036] Embodiment 3

[0037] The utility model provides a structure for maintaining the vacuum of the cavity during the process of absorbing metatitanic acid. Figure 1 As shown, the auxiliary vacuum pumping structure includes a third vacuum pumping tube 14 , one end of the third vacuum pumping tube 14 is connected to the upper part of one of the support tubes 4 , and the other end of the third vacuum pumping tube 14 is connected to the fourth vacuum pumping tube 15 .

[0038] The third vacuum pipes 14 are connected with a second on-off valve 16 . The second on-off valve 16 is located on a side close to the fourth vacuum pipe 15 . The fourth vacuum pipe 15 is a flexible pipe and has a length greater than the height of the storage pool 1 .

[0039] The tops of both sides of the support frame 2 are respectively connected with fixing ropes 17, and the upper ends of the fixing ropes 17 are connected with hanging rings 18, and the hanging rings 18 cooperate with the hooks 19 of the gantry crane.

[0040] The specific implementation manner of this embodiment is as follows: One end of the third evacuation tube is communicated with one of the support tubes, and the other end of the third evacuation tube is communicated with the fourth evacuation tube. When the support tube is removed from the first evacuation tube, the first opening and closing valve is closed at this time, and the second opening and closing valve is opened simultaneously. The suction force generated by the fourth evacuation tube is convenient to be transmitted to the adsorption plate, so as to facilitate the adsorption of the metatitanic acid blocks on the adsorption net.

[0041] Preferably, by setting the fourth evacuation tube as a flexible tube, it is convenient for the fourth evacuation tube to maintain the function of evacuating the inside of the support cavity during the process of moving along with the support tube; by setting the length of the fourth evacuation tube, it is convenient for the fourth evacuation tube to move along with the support tube.

[0042] Both sides of the support are respectively used to connect the fixing ropes. The upper ends of the fixing ropes are used to connect with a hanging ring, and then the hanging ring is hooked with the hook on the gantry crane, or the hook is removed from the hanging ring. Through the gantry crane, the whole structure of this application can be moved conveniently, and then the adsorption structure for adsorbing the metatitanic acid blocks can be removed from the storage place.

[0043] The above are only the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, and improvements made by those skilled in the art within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
