Description

Technical Field

[0001] This invention relates to the field of chemical spill handling equipment technology, and in particular to an emergency treatment device and its operating method for handling titanium tetrachloride spills. Background Technology

[0002] Titanium chloride, also known as titanium tetrachloride, is an inorganic compound with the chemical formula TiCl4. It is mainly used to produce sponge titanium and titanium dioxide, and can also be used as a catalyst. Titanium tetrachloride is a colorless, dense liquid. When the sample is impure, it is often yellow or reddish-brown. Similar to vanadium tetrachloride, it is one of the few transition metal chlorides that are liquid at room temperature. Its low melting and boiling points are related to the weak intermolecular forces. Most metal chlorides are polymers containing metal atoms connected by chlorine bridges, but the intermolecular forces of titanium tetrachloride are mainly weak van der Waals forces, hence its low melting and boiling points.

[0003] Titanium tetrachloride poses a significant hazard to human health. Direct skin contact with liquid titanium tetrachloride can cause burns of varying degrees. If leaks occur during the preparation or transportation of titanium tetrachloride and are not handled properly, they can cause enormous harm. Current technology uses soda ash to cover and absorb leaked titanium tetrachloride. However, manual ash application is not only inefficient but also makes it difficult to ensure the uniformity of the soda ash application. Furthermore, wearing protective clothing is required when manually handling titanium tetrachloride leaks, making ash application inconvenient.

[0004] Therefore, it is necessary to invent an emergency treatment device and its operation method for handling titanium tetrachloride leaks to solve the above problems. Summary of the Invention

[0020] The present invention also provides an operating method for an emergency treatment device for handling titanium tetrachloride leaks, comprising the following steps:

[0021] Step 1: Cover with ash. Move the device to the titanium tetrachloride leak area and then use the ash-spraying component to spray soda ash onto the ground in the titanium tetrachloride leak area.

[0022] Step 2: Spreading soda ash. The mobile device spreads the soda ash using the spreading components to ensure that the soda ash is fully mixed with the titanium tetrachloride on the ground.

[0023] Step 3: Waste recycling. The mobile device collects the soda ash mixed with titanium tetrachloride into a collection bin through the collection component. After the soda ash is collected, the collection bin is sealed.

[0024] Step 4: Alkaline water spraying. Use a sprayer to spray an alkaline aqueous solution such as lime water onto the titanium tetrachloride leak area in a misting manner to treat the titanium tetrachloride vapor. Alkaline water spraying can be carried out simultaneously with steps 1, 2 and 3.

[0025] The technical effects and advantages of this invention are as follows:

[0026] 1. This invention features a frame on which a spraying component, a spreading component, a collecting component, and a sprayer are mounted. The spraying component spreads soda ash, which covers and absorbs leaked titanium tetrachloride solution. The spreading component disperses the spread soda ash to ensure thorough mixing with the titanium tetrachloride liquid. The collecting component collects the soda ash containing titanium tetrachloride, thus enabling the treatment of titanium tetrachloride leaks. The device can be moved by pushing the frame. The spraying, spreading, and collecting components treat the titanium tetrachloride solution as they move with the frame, making it easy for users to operate the device, even while wearing protective clothing.

[0027] 2. The present invention provides a ash-spraying component, which includes a movable block with a guide trough and a movable guide plate. When the movable block rotates, the guide trough on its surface can convey the soda ash. The soda ash is conveyed through the movable block to the surface of the guide plate and slides down the guide plate onto the surface of the titanium tetrachloride solution, thereby achieving uniform feeding of the soda ash and ensuring the uniformity of the soda ash spreading.

[0028] 3. This invention incorporates a spreading component and a collecting component. The spreading component includes a movable plate and a pressure roller. The movable plate guides and gathers the soda ash so that the collecting component can collect it. The pressure roller applies pressure to the soda ash, flattening it on the surface of the titanium tetrachloride solution. The outer wall of the pressure roller has multiple annular grooves. When the pressure roller applies pressure to the soda ash, the soda ash is squeezed and slides towards the annular grooves to a certain extent, thereby improving the mixing effect of the soda ash and the titanium tetrachloride solution.

[0029] 4. This invention, through the cooperation of a sleeve, an elliptical protrusion, a control spring, a magnetic component, a sensing plate, a sensing spring, a sensor, a guide plate, a connecting arm, and a telescopic rod, can sense the mixing degree of soda ash and titanium tetrachloride solution. When mixing is insufficient, the controller controls the elliptical protrusion to protrude beyond a preset height on the turntable. Simultaneously, the speed of the drive motor is appropriately adjusted to increase the vibration of the guide plate, resulting in greater vibration when the elliptical protrusion contacts the movable wall. This increased vibration causes the soda ash to shake into the gap between the two pressure rollers, where it is blocked and rebounded by the elastic layer on the sensing plate, allowing the soda ash to fall... Even when soda ash is insufficient, a certain amount of soda ash can be applied again in the gap between the pressure rollers after passing through the pressure rollers, thereby improving the mixing effect. As the speed of the drive motor increases, the amount of soda ash applied increases. When the mixing effect is improved, the mixed mixture can form a micro-cluster structure, which can then squeeze the induction plate. The pressure of this squeezing can be detected by the sensor, and when a certain pressure value is maintained for a predetermined time, it is determined that the mixing effect meets the requirements. This allows the elliptical protrusion to be retracted into the sleeve, thereby effectively improving the mixing effect and the utilization efficiency of soda ash. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides, for example Figures 1 to 12 An emergency response device for handling titanium tetrachloride leaks is shown, comprising a frame 1, a dusting assembly 2, a spreading assembly 3, a collecting assembly 4, and a sprayer 5. The dusting assembly 2 and the sprayer 5 are both located above the frame 1, and the spreading assembly 3 and the collecting assembly 4 are both located below the frame 1.

[0045] The frame 1 includes a mounting frame 101, and each of the four corners of the lower surface of the mounting frame 101 is provided with a traveling wheel 102;

[0046] Mounting bracket 101 can be connected to an external remote control traction mechanism to realize remote control of the device, so that personnel do not need to wear protective clothing to operate the device;

[0047] The ash-spraying assembly 2 includes a transmission rod 201. Both ends of the transmission rod 201 are movably connected to a support seat 202 via bearings. The support seat 202 is fixedly mounted on the upper surface of the mounting frame 101 and can support the transmission rod 201.

[0048] Specifically, both ends of the outer side of the transmission rod 201 are provided with a ring-shaped fixed cover 203. A movable block 204 is fixedly installed inside the fixed cover 203, and the movable block 204 is fixedly installed on the outer side of the transmission rod 201. Multiple guide grooves 205 are formed around the outer wall of the movable block 204. A discharge frame 206 is fixedly installed in the middle of the bottom end of the fixed cover 203. A guide plate 207 is installed below the discharge frame 206. The drive motor 217 drives the transmission rod 201 to rotate, and the transmission rod 201 drives the movable block 204 to rotate. The movable block 204 is located within the fixed cover 201. 3. When the guide trough 205 on the outside of the movable block 204 moves to the top of the fixed cover 203, the soda ash in the storage box 216 falls into the guide trough 205 under the action of gravity. At this time, the movable block 204 drives the soda ash to move through the guide trough 205 until the soda ash moves to the bottom of the fixed cover 203. At this time, the soda ash falls onto the guide plate 207 through the discharge frame 206, and then slides down the guide plate 207 to the ground below the frame 1. At this time, the soda ash mixes with the titanium tetrachloride solution on the ground to achieve the coverage and adsorption of the titanium tetrachloride solution.

[0049] More specifically, one end of the guide plate 207 is movably connected to the outer wall of the discharge frame 206 via a pin, and the other end of the guide plate 207 is movably provided with a telescopic rod 208 via a pin. One end of the telescopic rod 208 is movably provided with the outer wall of the discharge frame 206 via a pin, and a tension spring is provided around the outer side of the telescopic rod 208. A movable arm 209 is movably provided with a pin in the middle of the upper surface of the guide plate 207, and a connecting arm 210 is movably provided with a pin at the top of the movable arm 209. The bottom end of the connecting arm 210 is movably provided with a pin at one end of the outer wall of the discharge frame 206, and a turntable 2 is provided at the top of the connecting arm 210. 11. The turntable 211 is fixedly set in the middle of the transmission rod 201. Multiple protrusions 212 are arranged around the outer side of the turntable 211. The movable rod 201 drives the turntable 211 to rotate, and the turntable 211 drives the protrusions 212 to rotate. When the protrusions 212 press the top of the movable arm 209, the movable arm 209 drives the guide plate 207 to move, so that the guide plate 207 rotates around the pin. When the protrusions 212 separate from the movable arm 209, the tension spring on the outer side of the telescopic rod 208 acts on the guide plate 207, so that the guide plate 207 returns to its original position. At this time, the guide plate 207 completes the shaking action, and the soda ash on the guide plate 207 is shaken off.

[0050] Furthermore, multiple fixing rods 213 are fixedly installed on the inner wall of the bottom end of the feed chute 205, and a cone-shaped crushing block 214 is fixedly installed at the top of the fixing rod 213. Multiple partitions 215 are fixedly installed inside the discharge frame 206, and the cross section of the partitions 215 is set as a triangular structure. The setting of the crushing block 214 can crush the agglomerated soda ash, and the setting of the partitions 215 can further improve the crushing effect of soda ash, thereby improving the covering and adsorption effect of soda ash on titanium tetrachloride solution.

[0051] Furthermore, a storage box 216 is fixedly installed above the fixed cover 203. The storage box 216 can store soda ash, and a funnel-shaped connecting pipe is provided between the storage box 216 and the fixed cover 203 to facilitate the transfer of soda ash. A drive motor 217 is fixedly installed at one end of the transmission rod 201, and the drive motor 217 is fixedly installed on the outer wall of the support base 202.

[0052] The paving assembly 3 includes a fixing frame 301, which is fixedly disposed in the middle of the lower surface of the mounting frame 101;

[0053] Specifically, movable plates 302 are movably mounted on both ends of the lower surface of the fixed frame 301 via pins. A groove 303 is formed in the middle of the upper surface of the movable plate 302. A slider 304 is disposed inside the groove 303. A threaded groove 305 is formed through the middle of the slider 304. A double-ended screw 306 is formed through the threaded groove 305. A bracket 307 is provided in the middle of the double-ended screw 306, and the bracket 307 is fixedly mounted on one side of the fixed frame 301. By rotating the double-ended screw 306, the two sliders 304... 4. Relative motion occurs, and the slider 304 can squeeze the inner wall of the groove 303, causing the two movable plates 302 to rotate around the pin shaft. This allows the opening range of the two movable plates 302 to be adjusted. When the leakage of titanium tetrachloride solution is large, the opening range of the two movable plates 302 can be reduced. At this time, the gathering range of the two movable plates 302 on the soda ash is reduced, and the gathering force of the movable plates 302 on the soda ash is improved. This can avoid the problem that the soda ash will stick to the ground and be difficult to gather due to excessive adsorption of titanium tetrachloride solution.

[0054] More specifically, the bottom end of the movable plate 302 is fixedly provided with an inclined scraper 308. The scraper 308 improves the agglomeration effect of the movable plate 302 on the soda ash. A movable frame 309 is provided on one side of the fixed frame 301. Fixed seats 310 are provided at the four corners of the upper surface of the movable frame 309. The fixed seats 310 are fixedly provided on the inner side wall of the mounting frame 101. A spring is provided between the fixed seat 310 and the movable frame 309. The spring provides a certain force between the fixed seat 310 and the movable frame 309, so that the pressure roller 311 can apply a certain pressure to the soda ash.

[0055] Furthermore, two pressure rollers 311 are provided below the movable frame 309. Multiple annular grooves 312 are provided on the outer side wall of the pressure rollers 311. The annular grooves 312 on the outer side of the two pressure rollers 311 are staggered. When the pressure rollers 311 apply pressure to the soda ash, the soda ash can slide towards the annular grooves 312 to ensure its flatness. At the same time, the mixing effect of the soda ash with the titanium tetrachloride solution is improved during the sliding process. Since the annular grooves 312 on the outer side of the two pressure rollers 311 are staggered, the two pressure rollers 311 cooperate to ensure the flattening effect of the soda ash.

[0056] The collecting component 4 includes a receiving hopper 401, which is fixedly disposed at one end of the lower surface of the mounting frame 101;

[0057] Specifically, a fixing block 402 is fixedly installed on the inner wall of the bottom end of the receiving hopper 401, and both sides of the fixing block 402 are set as inclined structures. The receiving hopper 401 can scoop up the mixture of soda ash and titanium tetrachloride. After the mixture of soda ash and titanium tetrachloride enters the receiving hopper 401, it slides along the inclined surface of one side of the fixing block 402 until the mixture of soda ash and titanium tetrachloride slides to one end of the conveyor belt 403. The inner side of the fixing block 402 is provided with the conveyor belt 403. A support 404 is provided on one side of the receiving hopper 401, and the support 404 is fixedly installed on one end of the mounting frame 101. A receiving bucket is provided above the support 404, and the receiving bucket is located below the conveyor belt 403. The conveyor belt 403 can transport the mixture of soda ash and titanium tetrachloride into the receiving bucket.

[0058] More specifically, connecting frames 405 are fixedly installed on the top of both sides of the receiving hopper 401, and the connecting frames 405 are fixedly installed on the inner side wall of the mounting frame 101. Adhesive wheels 406 are installed on the bottom of both sides of the receiving hopper 401. The setting of the adhesive wheels 406 allows one end of the receiving hopper 401 to slide on the ground. The diameter of the adhesive wheels 406 is small, which reduces the distance between the receiving hopper 401 and the ground while ensuring the sliding effect of the receiving hopper 401, thereby ensuring the material scooping effect of the receiving hopper 401.

[0059] Furthermore, due to the limited capacity of the storage tank in emergency response devices, the effective use of a limited amount of soda ash is crucial for timely handling of large-scale leaks. Moreover, in actual ash application, controlling the application rate is often difficult. Too low a rate results in insufficient mixed soda ash, leading to inadequate adsorption of the leaked titanium tetrachloride; conversely, too high a rate results in excessive soda ash. Therefore, if… Figure 11-12As shown, three sleeves 218 are provided on the turntable 211. The three sleeves 218 are located at the midpoint between two adjacent protrusions 212 and are evenly distributed around the center of the turntable. A control spring 220 is provided inside each sleeve 218. One end of the control spring 220 is fixedly connected to the bottom of the sleeve 218, and the other end is fixedly connected to an elliptical protrusion 219. A magnetic component 221 is provided at the bottom of each sleeve 218, and the elliptical protrusion is magnetic. By retracting or not retracting the control spring through the sleeves 218, the protrusion amount of the elliptical protrusion 219 can be effectively controlled. The height difference between the convex elliptical protrusion 219 and the turntable, and between the elliptical protrusion 219 and the protrusion 212, is adjusted within a certain time period to regulate the vibration degree of the guide plate 207. When the vibration degree reaches a predetermined level, the soda ash can enter the gap between the two pressure rollers 311 under this vibration level. The soda ash can then adsorb a small amount of the insufficiently mixed titanium tetrachloride after being squeezed by the previous pressure roller, improving the uniformity of adsorption. A sensing plate 313 is provided at the bottom of the movable frame 309 and between the two pressure rollers 311. The sensing plate 313 is rotatably connected to the movable frame 309 via a rotating shaft. The sensing plate 313 is closer to the movable frame 309. A sensing spring 314 is provided between one end of the bottom of the frame 309 and the movable frame 309. One end of the sensing spring 314 is connected to one side of the sensing plate, and the other end of the sensing spring 314 is connected to the bottom of the movable frame 309 through a sensor 315. An elastic layer is provided on the side of the sensing plate away from the sensing spring 314. With the above arrangement, when the mixing is insufficient, the proportion of titanium tetrachloride solution is high and the proportion of soda ash is too small. The corresponding mixture has a certain fluidity, which can also be understood as insufficient adhesion to the pressure roller 311, so that a certain thickness of mixture will not accumulate on the pressure roller. When the mixing is sufficient, the soda ash can better adsorb titanium tetrachloride. The solution, which has a certain viscosity and insufficient fluidity, will adsorb a certain thickness of mixture on the pressure roller. This mixture can exert a squeezing effect on the lower end of the sensing plate 313, and this squeezing is a continuous action. Although local unevenness may cause short periods of non-squeezing, the whole process can be understood as continuous. The controller receives the pressure change signal and can judge the mixing effect in a timely and effective manner. The controller is configured to receive the pressure signal from the sensor 315, and when the pressure signal is less than a preset value, disconnect the magnetic connection between the magnetic component 221 and the elliptical protrusion 219, so that the elliptical protrusion 219 is housed in the sleeve 218.The pressure signal received by the sensor 315 is controlled to repel the magnetic component 221 and the elliptical protrusion 219 when the pressure signal is greater than or equal to the preset value. This causes the elliptical protrusion to stretch the control spring 220 and the elliptical protrusion 219 to protrude from the sleeve by a preset distance, which is greater than the radius of the protrusion 212.With the above settings, when mixing is insufficient, the controller can control the elliptical protrusion 219 to protrude beyond the turntable 211, and the protrusion distance is greater than the radius of the protrusion 212. This makes the height difference between the elliptical protrusion 219 and the turntable 211 greater than the height difference between the protrusion and the turntable 211, improving the shaking effect. This allows some soda ash to enter the gap between the two pressure rollers 311. Through the elastic layer on the sensing plate 313, the soda ash can be effectively and evenly dispersed in the gap, thereby supplementing the insufficiently mixed mixture to a certain extent, making the mixture relatively uniform. When the speed of the drive motor 217 increases to a certain level, the mixing is already relatively uniform. At this time, a certain thickness of the mixture will adhere to the pressure roller. This mixture can exert a squeezing effect on the lower end of the sensing plate 313, and this squeezing is continuous. Although local unevenness may cause short periods of non-squeezing, the whole process can be understood as continuous. The controller receives the above pressure change signal and can judge the mixing effect in a timely and effective manner. By repeatedly judging the above process, uniform mixing can be achieved throughout the process. Even when there are multiple leakage levels at different locations in the leakage area, it can be understood that the thickness or amount of titanium tetrachloride leakage varies in different areas. The technical solution of this invention can accurately identify these areas and adjust the soda ash sprinkling speed, as well as supplement the insufficiently mixed mixture with additional sprinkling. This invention, through the cooperation of a sleeve, elliptical protrusion, control spring, magnetic components, induction plate, induction spring, sensor, guide plate, connecting arm, and telescopic rod, can sense the mixing degree of soda ash and titanium tetrachloride solution. When mixing is insufficient, the controller controls the elliptical protrusion, causing it to protrude beyond the preset height of the turntable. Simultaneously, the speed of the drive motor is appropriately adjusted to increase the vibration of the guide plate, resulting in greater vibration when the elliptical protrusion contacts the movable wall. This increased vibration causes the soda ash to fall into the gap between the two pressure rollers, where it is blocked and rebounded by the elastic layer on the induction plate, allowing the soda ash to fall onto the ground. Even when soda ash is insufficient, a certain amount of soda ash can be added again through the gap between the pressure rollers after passing through the rollers, thereby improving the mixing effect. Furthermore, as the drive motor speed increases, the amount of soda ash applied increases. Once the mixing effect is achieved, the mixture forms micro-clumps, which can then compress the induction plate. This compression pressure is detected by a sensor, and if a certain pressure value is maintained for a predetermined time, the mixing effect is determined to be satisfactory. This allows the elliptical protrusion to retract back into the sleeve, effectively improving the mixing effect and the utilization efficiency of the soda ash.

[0060] The present invention also provides an operating method for an emergency treatment device for handling titanium tetrachloride leaks, comprising the following steps:

[0061] Step 1: Cover with ash. Move the device to the titanium tetrachloride leak area and then use the ash-spraying component 2 to spray soda ash onto the ground in the titanium tetrachloride leak area.

[0062] When the ash-spreading component 2 spreads soda ash, the drive motor 217 drives the transmission rod 201 to rotate, and the transmission rod 201 drives the movable block 204 to rotate. The movable block 204 rotates in the fixed cover 203. When the guide trough 205 on the outside of the movable block 204 moves to the top of the fixed cover 203, the soda ash in the storage box 216 falls into the guide trough 205 under the action of gravity. At this time, the movable block 204 drives the soda ash to move through the guide trough 205 until the soda ash moves to the bottom of the fixed cover 203. At this time, the soda ash falls onto the guide plate 207 through the discharge frame 206, and then slides down the guide plate 207 to the ground below the frame 1. At this time, the soda ash mixes with the titanium tetrachloride solution on the ground to achieve the coverage and adsorption of the titanium tetrachloride solution.

[0063] During the spreading of soda ash, the movable rod 201 drives the turntable 211 to rotate, and the turntable 211 drives the protrusion 212 to rotate. When the protrusion 212 presses the top of the movable arm 209, the movable arm 209 drives the guide plate 207 to move, causing the guide plate 207 to rotate around the pin. When the protrusion 212 separates from the movable arm 209, the tension spring on the outside of the telescopic rod 208 acts on the guide plate 207, causing the guide plate 207 to return to its original position. At this time, the guide plate 207 completes the shaking action, and the soda ash on the guide plate 207 is shaken off.

[0064] Step 2: Spreading soda ash. The mobile device spreads the soda ash using spreading component 3 while spreading the soda ash to ensure that the soda ash is fully mixed with the titanium tetrachloride on the ground.

[0065] When the paving component 3 spreads soda ash, the mounting frame 101 drives the pressure roller 311 to move. During the movement, the pressure roller 311 can flatten the uneven soda ash. Since the outer wall of the pressure roller 311 has multiple annular grooves 312, when the pressure roller 311 applies pressure to the soda ash, the soda ash can slide towards the annular grooves 312 to ensure its flatness. At the same time, during the sliding process, the mixing effect of the soda ash with the titanium tetrachloride solution is improved. Since the annular grooves 312 on the outer sides of the two pressure rollers 311 are staggered, the two pressure rollers 311 cooperate to ensure the flattening effect of the soda ash. After flattening, the soda ash is gathered towards the center of the device by the scraper 308 at the bottom of the movable plate 302, waiting to be collected by the collection component 4.

[0066] Step 3: Waste recycling. The mobile device collects the soda ash mixed with titanium tetrachloride into the collection bin through the collection component 4. After the soda ash is collected, the collection bin is closed.

[0067] When collecting the mixture of soda ash and titanium tetrachloride, the collecting hopper 401 moves with the mounting frame 101. The collecting hopper 401 can scoop up the mixture of soda ash and titanium tetrachloride. After entering the collecting hopper 401, the mixture of soda ash and titanium tetrachloride slides along the inclined surface of the fixed block 402 until it slides to one end of the conveyor belt 403. At this time, the conveyor belt 403 can transport the mixture of soda ash and titanium tetrachloride to the collecting bucket, thus completing the collection of the mixture of soda ash and titanium tetrachloride.

[0068] Step 4: Alkaline water spraying. Use sprayer 5 to spray an alkaline aqueous solution such as lime water onto the titanium tetrachloride leak area in a misting manner to treat the titanium tetrachloride vapor. Alkaline water spraying can be carried out simultaneously with steps 1, 2, and 3. Sprayer 5 includes a water tank for storing alkaline water, a booster pump, and atomizing nozzles. The alkaline water is sprayed into the air in the titanium tetrachloride leak area in a misting manner. The alkaline water can be mixed with the titanium tetrachloride vapor to avoid the titanium tetrachloride vapor causing harm. When the titanium tetrachloride leak is large, the titanium tetrachloride solution on the ground can be treated with soda ash first, and then the titanium tetrachloride vapor in the air can be treated with alkaline water.

[0069] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
