Description

Technical Field

[0001] The present invention relates to the technical field of zirconium and hafnium production, in particular to a weighing and sealing device and method for soft connection between the outlet of zirconium tetrachloride and a storage and transportation tank in the production of zirconium tetrachloride. Background Art

[0002] Currently, in the production of zirconium and hafnium, the receiving and transfer of zirconium tetrachloride condensate materials are completed in the zirconium tetrachloride condensate material receiving workshop. The receiving workshop is provided with a hoisting area I and a receiving area II. The collection and transfer process is as follows: First, use a crane to hoist the storage and transportation tank to the hoisting area I of the receiving workshop, place the storage and transportation tank on a forklift, and then use the forklift to transfer the storage and transportation tank from the hoisting area I to the receiving port of the receiving area II. In the receiving area II, the zirconium tetrachloride condensate material is fed from the outlet of the primary condenser to the receiving port of the zirconium tetrachloride condensate material storage and transportation tank. The storage and transportation tank collects the zirconium tetrachloride condensate material. After the receiving is completed, the storage and transportation tank filled with zirconium tetrachloride condensate is transferred from the receiving area II to the hoisting area I by a forklift, and then lifted to the purification workshop by a crane. The entire receiving and transfer process is completed manually.

[0003] Currently, the main problems existing in the process of zirconium tetrachloride collection and transfer are as follows:

[0004] 1. During the receiving process, the connection between the receiving port of the storage and transportation tank and the outlet of zirconium tetrachloride is not tight, resulting in spraying of materials during discharging. Since chlorine gas will be released from the zirconium tetrachloride condensate material, chlorine gas reacts with moisture in the air

[0005] to produce hydrochloric acid smoke upon contact, causing environmental pollution.

[0006] 2. In the prior art, the zirconium tetrachloride pipelines are all rigidly connected through flange plates and bolts. During the process of filling the storage and transportation tank with zirconium tetrachloride, workers manually tap the storage and transportation tank and judge whether the zirconium tetrachloride in the storage and transportation tank is full by listening to the sound inside the storage and transportation tank. The method of manually tapping the storage and transportation tank to judge whether the zirconium tetrachloride in the storage and transportation tank is full is difficult to accurately judge the fullness degree of zirconium tetrachloride in the storage and transportation tank, and it will cause overfilling and underfilling phenomena in the storage and transportation tank. This phenomenon will have two negative impacts. First, the underfilling phenomenon will affect the next process of zirconium tetrachloride reduction, resulting in a decrease in product output and product profit. Second, the overfilling phenomenon will affect the connection between the next receiving port and the outlet of zirconium tetrachloride, and at the same time, the overflowing chlorine gas will affect the environment and

[0007] cause loss of some zirconium tetrachloride products.

[0008] 3. In the prior art, workers manually operate the forklift to the position of the zirconium tetrachloride outlet. The positioning time is long and the positioning is inaccurate. The manual operation is used to complete the threaded connection between the zirconium tetrachloride outlet and the receiving port of the storage and transportation tank

[0009] with low efficiency and inaccurate sealing position.

[0010] 4. Currently, the transfer process of zirconium tetrachloride collection and storage and transportation tanks is completed manually. The labor intensity of workers is high and the efficiency is low. Operators need to wear protective clothing and gas masks to work in an environment with harmful substances such as hydrochloric acid fumes

[0011] and other harmful substances, which seriously affects the occupational safety and health of workers. Summary of the Invention

The push rod connecting seat is installed at the bottom of the moving platform and is connected to the horizontal electric push rod. The moving platform is driven by the horizontal electric push rod to move, so as to position the storage and transportation tank.

[0023] A still further technical solution of the present invention is that a laser rangefinder is installed on the electromagnetic iron limit device in the lifting area, and the laser rangefinder is used to measure the moving position of the transfer trolley.

[0024] The method applied to the weighing and sealing device for the soft connection between the zirconium tetrachloride discharge port and the storage and transportation tank described above includes the following process:

[0025] A. Before the start of loading, the hydraulic cylinder controls the transfer trolley to move to the lifting area. At the same time, the electromagnetic iron of the electromagnetic iron limit device in the lifting area is energized, and the electromagnetic iron on the transfer trolley adsorbs the iron plate and is adsorbed together with this electromagnetic iron, and the transfer trolley is fixed in the lifting area.

[0026] B. The storage and transportation tank to be loaded is transported to the center of the electronic scale on the transfer trolley by a crane and is positioned by four positioning wheels. The horizontal electric push rod on the positioning guide wheel member is started to push the moving platform forward, and the guide wheel on the moving platform contacts the storage and transportation tank.

[0027] C. The electromagnetic iron of the electromagnetic iron limit device in the lifting area is powered off. The hydraulic cylinder controls the transfer trolley to move to the material receiving area. At the same time, the electromagnetic iron of the electromagnetic iron limit device in the material receiving area is energized, and the electromagnetic iron on the transfer trolley adsorbs the iron plate and is adsorbed together with the electromagnetic iron. The transfer trolley equipped with the storage and transportation tank is fixed in the material receiving area.

[0028] D. The electromagnet of the electromagnet limit device in the material receiving area is powered off, and the laser rangefinder is started. The position error between the material receiving port of the storage tank and the material outlet of the lower tube of the corrugated pipe on the feeding component is corrected by fine-tuning the hydraulic cylinder so that the upper end of the material receiving port of the storage tank is located between the bottom plate and the pressure plate of the mounting frame on the clamping component.

[0029] E. Start the three vertical electric push rods of the clamping component to drive the pressure plate to move downward. During the movement, the pressure plate presses on the flange of the lower tube of the bellows, thereby pressing the flange of the lower tube of the bellows onto the flange of the material receiving port of the storage tank.

[0030] F. The electromagnet on the clamping member is energized, and the electromagnet adsorption iron plate on the clamping member is adsorbed together with the electromagnet on the clamping member, and the flange of the lower tube of the bellows is tightly sealed with the flange of the receiving port of the storage tank; the end of the vertical electric push rod continues to extend downward, and since the pressure plate and the flange of the lower tube of the bellows are fixed, the vertical electric push rod moves upward, thereby driving the entire clamping member to move upward relative to the clamping support member and separate from the clamping support plate, and recording the weight W1 displayed on the electronic scale. At this time, W1 is the sum of the weights of the clamping member, the lower tube of the bellows of the feeding member, and the storage tank.

[0031] G. Start the pneumatic flange butterfly valve of the feeding component. The material enters the storage tank through the feeding pipe, the upper tube of the bellows, the bellows, the lower tube of the bellows and the material receiving port of the storage tank. The weight W2 displayed on the electronic scale is used to calculate the weight of the material entering the storage tank in real time (W=W2-W1). During the feeding process, start the smoke detector to monitor in real time whether there is any leakage of the feed.

[0032] H. When the weight W of the material entering the storage tank reaches the set weight, the pneumatic flange butterfly valve of the feeding component is closed, the electromagnet on the clamping component is powered off, the electromagnet on the clamping component adsorbs the iron plate and the electromagnet on the clamping component is released, the vertical electric push rod is controlled to shrink, the pressure plate moves upward to drive the lower tube of the bellows to move upward, and the feeding component is separated from the storage tank; the hydraulic cylinder controls the transfer trolley to move to the lifting area, starts the horizontal electric push rod on the positioning guide wheel component to push the mobile platform to move backward, the guide wheel on the mobile platform is separated from the storage tank, and the storage tank containing the material is transported by the crane for the next step of processing.

[0033] Compared with the prior art, the present invention has the following characteristics:

[0034] 1. The present invention uses an electromagnet limiter and a laser distance sensor to enable the storage tank to be accurately stopped and fixed directly below the material receiving port without deviation.

[0035] 2. The docking process between the storage tank and the material receiving port of the present invention is accurate, fast and tight, which reduces the overflow of chlorine and the generation of hydrochloric acid fumes, improves the environment of the workshop, and reduces damage to the human body and corrosion of instruments and equipment.

[0036] 3. The material receiving process of the present invention realizes remote automatic control, avoiding operators from working in an environment with harmful substances such as hydrochloric acid fumes while wearing protective clothing and gas masks, reducing the harm to workers' bodies, lowering the labor intensity of workers, saving manpower, and improving efficiency.

[0037] 4. During the material receiving process of the present invention, an electronic scale dynamically displays the weight of the material entering the storage and transportation tank in real time, enabling the judgment of whether the feeding of zirconium tetrachloride in the storage and transportation tank meets the requirements.

[0038] 5. The present invention is equipped with a smoke alarm, which monitors the discharging process and the situation in the workshop in real time, can warn of dangers, and reduce accidents.

[0081] C. The electromagnet 4-1 of the hoisting area electromagnet limiting device 4 is powered off. The hydraulic cylinder 3 controls the transfer cart 1 to move to the material receiving area. At the same time, the electromagnet 5-1 of the material receiving area electromagnet limiting device 5 is energized, and the electromagnet on the transfer cart 1 adsorbs the iron plate 1-3 to be adsorbed together with the electromagnet 5-1, so that the transfer cart 1 is fixed in the material receiving area.

[0082] D. The electromagnet 5-1 of the material receiving area electromagnet limiting device 5 is powered off. The laser rangefinder 4-2 is started, and the position error between the material receiving port of the storage and transportation tank 9 and the discharge port of the lower pipe 8-5 of the bellows on the feeding member 8 is finely adjusted and corrected by the hydraulic cylinder 3. Since the laser rangefinder 4-2 has good sealing performance, it can resist the influence of the corrosive environment in the zirconium tetrachloride material receiving workshop, ensuring the reliability of the laser rangefinder 4-2 during the working process, and ensuring that the upper end of the material receiving port of the storage and transportation tank 9 is located between the bottom plate and the pressing plate 7-4 of the mounting bracket 7-1 on the pressing member 7, as Figure 12 shown.

[0083] E. The three vertical electric push rods 7-2 of the pressing member 7 are started to drive the pressing plate 7-4 to move downward. During the movement, the pressing plate 7-4 presses on the flange of the lower pipe 8-5 of the bellows, thereby pressing the flange of the lower pipe 8-5 of the bellows firmly on the flange of the material receiving port of the storage and transportation tank 9.

[0084] F. The electromagnet 7-6 on the clamping member 7 is energized, and the electromagnet adsorption iron plate 7-5 on the clamping member 7 is adsorbed together with the electromagnet 7-6 on the clamping member 7, so that the flange of the bellows lower tube 8-5 is tightly sealed with the flange of the material receiving port of the storage tank 9. The end of the vertical electric push rod 7-2 continues to extend downward. Since the pressing plate 7-4 is fixed to the flange of the bellows lower tube 8-5, the vertical electric push rod 7-2 moves upward, thereby driving the entire clamping member 7 to move upward relative to the clamping support member 6 and separate from the clamping support plate. Figure 13 As shown, the weight W1 displayed by the electronic scale 1-4 is recorded. At this time, W1 is the sum of the weights of the pressing member 7, the bellows lower tube 8-5 of the feeding member 8, and the storage tank 9.

[0085] G. Start the pneumatic flange butterfly valve 8-2 of the feeding component 8. The material enters the storage tank 9 through the feeding pipe 8-1, the upper tube 8-3 of the bellows, the bellows 8-4, the lower tube 8-5 of the bellows and the material receiving port of the storage tank 9. The weight W2 displayed on the electronic scale 1-4 is used to calculate the weight W=W2-W1 of the material entering the storage tank 9 in real time.

[0086] During the feeding process, the smoke detector 6-1-4 is started to monitor in real time whether there is any leakage of the feed; since the clamping member 7 is separated from the clamping support member 6 during the feeding process, the weight W2 displayed on the electronic scale 1-4 is not affected by the clamping support member 6, and the bellows lower tube 8-5 in the feeding member 8 is softly connected to other components of the feeding member 8 through the bellows 8-4, the weight W2 displayed on the electronic scale 1-4 is also not affected by other components of the feeding member 8, but is only related to the sum W1 of the weights of the clamping member 7, the bellows lower tube 8-5 of the feeding member 8 and the storage tank 9, so the calculated weight W of the material is more accurate than the existing weighing device.

[0087] H. After the weight W of the material entering the storage tank 9 reaches the set weight, the pneumatic flange butterfly valve 8-2 of the feeding component is closed, the electromagnet 7-6 on the clamping component 7 is powered off, the electromagnet adsorbs the iron plate 7-5 on the clamping component 7 and the electromagnet 7-6 on the clamping component 7 is released, the vertical electric push rod 7-2 is controlled to shrink, the pressure plate 7-4 moves upward to drive the lower tube 8-5 of the bellows to move upward, and the feeding component 8 is separated from the storage tank 9; the hydraulic cylinder 3 controls the transfer trolley 1 to move to the lifting area, starts the horizontal electric push rod 1-6-3 on the positioning guide wheel component 1-6, and pushes the mobile platform 1-6-8 to move backward, and the guide wheel 1-6-9 on the mobile platform 1-6-8 is separated from the storage tank 9, and the storage tank 9 containing materials is transported by the crane for the next step of processing.
