Description

Technical Field

[0001] The invention relates to the technical field of etching liquid transportation, and in particular to a storage tank for etching liquid transportation. Background Art

[0002] In the field of etching liquid transportation technology, a storage tank composed of a tank body, a universal wheel and a threaded pipe is usually used to store etching liquid. The tank body is moved to a transport vehicle using the universal wheel, and the staff injects the etching liquid from the threaded pipe into the inner side of the tank body for temporary storage and ensures sealing. At the same time, a safety valve is used to ensure the pressure safety in the tank body, and the storage tank storing the etching liquid is transported using a transport vehicle. However, there are still problems in the actual operation of the traditional etching liquid transfer storage tank.

[0003] For example, in actual operation, the transportation of etching liquid usually needs to be kept stable to reduce shaking. After the storage tank is moved to the transport vehicle, if it is not arranged tightly enough, it will be displaced due to the inertia generated during transportation, and the etching liquid will shake too much, resulting in a greater risk of etching liquid leakage or storage tank damage.

[0076] The fixed connection part includes a linkage part and a magnetic fixed part, the linkage part is connected to the magnetic fixed part, the linkage part is lifted and lowered through the tank body 1, and is elastically sealed and connected to the tank body 1, and is connected to the cover part, so as to push the magnetic fixed part down when the etching liquid is added, and the magnetic fixed part is located under the tank body 1, so as to use magnetic force to absorb and position the tank body 1 after being pushed down;

[0077] The retracting part includes a rotating member and a wheel-shifting member. The rotating member is connected to the tank body 1 and the linkage member, and the wheel-shifting member is connected to the universal wheel 41 and the rotating member to drive the universal wheel 41 to be retracted upwards when the magnetic fixed member descends.

The threaded tube 5 can provide a channel for the etching liquid to pass through the tank body 1 and enter the inner liner 3 for storage, and the inner liner 3 can provide a storage space for the etching liquid.

[0080] In the actual application of this embodiment: the staff can pull or push the tank body 1 through the handle 2 according to the actual needs, so that the tank body 1 drives the universal wheel 41 to roll through the screw 37 and the rotating rod 40. At the same time, the universal wheel 41 will rotate with the rotating rod 40 as the center according to the direction of the external force using the friction with the ground, so that the tank body 1 can drive the inner tank 3 to move through the support frame 4, so that the transfer storage tank can be moved to the transport vehicle for transportation. The staff can remove the threaded cover 6 from the threaded tube 5 by the threaded action as needed, and then inject the etching liquid into the inner side of the threaded tube 5. The etching liquid will pass through the tank body 1 along the threaded tube 5 and enter the inner side of the inner tank 3.

[0081] As a preferred embodiment of the present invention, the support member comprises:

[0082] The inner liner 3 is fixed to the inner side of the tank body 1 and is sleeved outside the threaded tube 5;

[0083] A support sleeve 9 is fixed on the inner side of the inner liner 3;

[0084] The inclined holes 10 are evenly arranged throughout the interior of the support sleeve 9.

[0085] Specifically, the inner tank 3 can provide storage space for the etching liquid and can provide stable support for the support sleeve 9. The support sleeve 9 has an inclined angle, can provide a resisting and buffering effect for the etching liquid, and can provide a through channel for the etching liquid. The support sleeve 9 can provide an opening space for the inclined hole 10. The inclined hole 10 has an inclined angle, which can provide a circulation channel for the etching liquid, so that the etching liquid falling on the support sleeve 9 can pass through the etching liquid and the inclined hole 10 and fall onto the pressure plate 11.

[0086] The closure includes:

[0087] The hydraulic parts are arranged on the inner side of the inner tank 3 and below the support sleeve 9;

[0088] A pull rod 15, one end of which is fixed to the hydraulic part, and the other end of which passes through the support sleeve 9;

[0089] A plug disc 16 is fixed to the other end of the pull rod 15;

[0090] The pressing plate 11 is arranged on the inner side of the inner liner 3 and below the supporting sleeve 9 .

[0091] Specifically, the pull rod 15 can provide support for the plug disc 16 under the support of the pressure plate 11. The plug disc 16 is made of rubber and can fit with the inner side of the support sleeve 9 to play a sealing role. It also has an inclined angle and can provide a resisting and guiding effect for the etching liquid passing through the threaded tube 5, so that the etching liquid flows to the support sleeve 9 and passes through the support sleeve 9 and falls onto the pressure plate 11.

[0092] Hydraulic parts include:

[0093] There are multiple first telescopic rods 12, the fixed ends of the multiple first telescopic rods 12 are evenly fixed in the pressing plate 11, and the telescopic ends of the first telescopic rods 12 are located outside the pressing plate 11;

[0095] The rubber sleeve 14 is symmetrically fixed on the outside of the pressing plate 11, adjacent to the rubber strip 13, and located on the outside of the first telescopic rod 12, connected to the telescopic end of the first telescopic rod 12, and the end of the rubber sleeve 14 away from the pressing plate 11 is in contact with the inner wall of the liner 3.

[0096] Specifically, the pressing plate 11 can provide stable support for the rubber strip 13, and can provide stable support for the rubber sleeve 14 and the first telescopic rod 12. The first telescopic rod 12 can provide support for the rubber sleeve 14. The rubber sleeve 14 can shrink and fold under the squeeze of external force, and can use external force to push the first telescopic rod 12 to shrink under the support of the pressing plate 11.

The rubber strip 13 and the rubber sleeve 14 are made of rubber material, can fit with the inner wall of the liner 3, play a sealing role, and cooperate with the pressing plate 11 to provide support for the etching liquid above.

[0097] In the actual application of this embodiment, when the etching liquid passing through the support sleeve 9 falls on the pressing plate 11, the pressing plate 11 will move downward along the inner wall of the inner liner 3 as the etching liquid injected into the inner liner 3 increases, and the gravity of the etched liquid moves downward, and in the process of movement, the rubber strip 13, the rubber sleeve 14 and the first telescopic rod 12 are driven to move downward together. At the same time, the rubber sleeve 14 and the first telescopic rod 12 are squeezed by the contour of the inner liner 3 and the external force during the movement, so that the first telescopic rod 12 and the rubber sleeve 14 shrink under the support of the pressing plate 11, and the rubber sleeve 14 uses elasticity to keep in contact with the inner wall of the inner liner 3. As the pressing plate 11 moves downward, the pressing plate 11 will simultaneously drive the pull rod 15 to move downward together, so that the pull rod 1 Under the action of external force, the plug disc 16 is driven to move downward together. When the etching liquid is about to fill the space in the inner container 3 between the pressing plate 11 and the support sleeve 9, the pressing plate 11 will pull the plug disc 16 downward to fit with the inner side of the support sleeve 9 through the pull rod 15 under the action of the weight of the etching liquid, thereby closing the inner opening of the support sleeve 9. At this time, the etching liquid is stopped from being added to the threaded tube 5, and the excess etching liquid on the support sleeve 9 and the plug disc 16 will pass through the support sleeve 9 through the inclined hole 10, so that the plug disc 16 and the support sleeve 9 limit the liquid level of the etching liquid injected into the inner container 3, so that the etching liquid has enough buffer space in the inner container 3, and provide resistance for the liquid surface of the etching liquid, reduce shaking, and prevent the liquid from overflowing due to shaking or temperature changes.

[0120] In the actual application of this embodiment, when the pressing plate 11 is pushed downward by the weight of the etching liquid, the connecting rod 19 is pushed downward by the external force, so that the connecting rod 19 uses the external force and friction force to push the rubber ring 18 to rotate under the support of the first support ring 17, so that the connecting rod 19 can pass through the rubber ring 18 and move downward. At the same time, the connecting rod 19 pushes the cone plate 20 downward under the action of the external force, so that the cone plate 20 uses the external force to move downward through the arc edge hole 43 under the support of the tank body 1 and stretch the elastic sleeve 21, so that one end of the elastic sleeve 21 passes through the arc edge hole 43, and the cone plate 20 is downward. During the movement, the connecting disk 22 is pushed downward, and the connecting plate 23 is pushed downward by the connecting disk 22, so that the connecting plate 23 uses external force to drive the fixing plate 24 and the magnet 25 to move downward together, so that the magnet 25 can contact the transport vehicle and be adsorbed on the transport vehicle by the magnetic force of the magnet 25, thereby utilizing the magnetic connection with the transport vehicle to position the tank body 1 on the transport vehicle through the magnet 25, the fixing plate 24, the connecting disk 22, the cone disk 20, the elastic sleeve 21, the connecting rod 19, the rubber ring 18 and the first support rod to prevent the tank body 1 from being displaced due to the inertia generated during the driving of the transport vehicle.

[0121] When it is necessary to release the positioning of the tank body 1, the staff can rotate the bolt 32 according to the actual needs, so that the bolt 32 moves downward by utilizing the threaded action with the fixing plate 24, and drives the roller 33 to move downward and contact the transport vehicle during the movement, and uses the threaded action of the bolt 32 and the fixing plate 24 to continue to push the roller 33 downward, so that the roller 33 in contact with the transport vehicle uses the reaction force to lift the fixing plate 24 upward, so that the fixing plate 24 uses external force to drive the magnet 25 adsorbed on the transport vehicle to separate from the transport vehicle, thereby releasing the positioning of the tank body 1, and when the staff needs to push the tank body 1 to move, the bolt 32 will provide support for the roller 33, and when the roller 33 contacts the transport vehicle or the ground, it will use the friction between the external force and the ground to rotate on the inside of the opening under the support of the bolt 32, and at the same time, the bolt 32 will rotate according to the direction of movement of the tank body 1 and using the friction of the roller 33, thereby preventing the bolt 32 from affecting the movement of the tank body 1.

[0122] When the connecting plate 22 is pushed downward by the connecting rod 19 and the conical plate 20, the connecting plate 22 will use external force to drive the side plate 26 to descend together, so that the side plate 26 pulls the curved rod 28 downward through the cross bar 29. The curved rod 28 will pull the telescopic end of the second telescopic rod 27 downward under the action of the external force, so that the second telescopic rod 27 is stretched and extended under the support of the tank body 1. At the same time, the curved rod 28 will push the anti-skid pad 31 downward under the reinforcement of the cross bar 29 and the reinforcement rod 30, so that the anti-skid pad 31 is in close contact with the transport vehicle, and the roughness of the anti-skid pad 31 is used to increase the friction force, and cooperate with the magnet 25 to prevent the tank body 1 from being displaced during transportation.

[0123] In another preferred embodiment of the present invention, the coupling member comprises:

[0124] The second support ring 34 is fixedly mounted on the outer side of the cone 20;

[0125] The bearing 35 is embedded in the side of the tank body 1 close to the connecting plate 23 and is located below the arc edge hole 43;

[0126] The winding reel 36 is connected to the inner side of the bearing 35 and is threadedly connected to the outer side of the second support ring 34 .

[0127] Specifically, the cone disk 20 can provide stable support for the second support ring 34 , the tank body 1 can provide support for the bearing 35 , the bearing 35 can provide rotational support for the winding drum 36 , and the winding drum 36 can provide a winding and winding space for the pull rope 42 .

[0128] The shifting wheel parts include:

[0129] The screw 37 has a thread that penetrates the side of the tank body 1 away from the threaded tube 5 and corresponds to the position of the universal wheel 41;

[0130] The rotating rod 40 is rotatably connected to the universal wheel 41 and fixedly connected to one end of the screw rod 37 close to the universal wheel 41;

[0131] The spring 38 is sleeved on the outside of the screw rod 37, and one end of the spring 38 is connected to the tank body 1;

[0132] One end of the pull rope 42 is fixedly connected to the rotating rod 40 and rolled up on the outside of the rotating rod 40 , and the other end is connected to the winding drum 36 .

[0133] Specifically, a baffle plate 39 is fixedly mounted on the outer side of the rotating rod 40, and the baffle plate 39 is fixedly connected to the other end of the spring 38. The tank body 1 can provide threaded support for the screw rod 37, so that the thread can firmly support the rotating rod 40. The rotating rod 40 can provide rotational support for the universal wheel 41, and the baffle plate 39 can provide support for the spring 38. The tank body 1 can provide support for the other end of the spring 38. The spring 38 is elastic and can be deformed under the action of external force, and will rebound after the external force disappears. The pull rope 42 can be bent and deformed arbitrarily under the action of external force. The rotating rod 40 can provide a winding and reeling space for the pull rope 42, and the baffle plate 39 can prevent the pull rope 42 reeled on the outer side of the rotating rod 40 from falling off.

[0134] In actual application of this embodiment, when the connecting rod 19 pushes the cone disk 20 downward under the action of external force, the cone disk 20 will drive the second support ring 34 to move downward together under the action of external force. At the same time, the second support ring 34 will use the thread action to push the winding disk 36 to rotate under the support of the bearing 35 under the action of external force and during the movement, so that the winding disk 36 uses external force to wind up the pull rope 42 during the rotation process, so that the pull rope 42 uses external force to pull the rotating rod 40 to rotate during the winding process. At the same time, the rotating rod 40 will drive the screw rod 37 to rotate together, so that the screw rod 37 uses the rotational power and the thread action with the tank body 1 to move upward, and then the screw rod 37 drives the universal wheel 41 to move upward through the rotating rod 40, and the universal wheel 41 will separate from the ground after the magnet 25 contacts the transport vehicle;

[0135] After the tank body 1 is transported, the staff can open the discharge valve 8 so that the etching liquid in the inner tank 3 can enter and pass through the discharge valve 8 to be discharged to the outside. After the etching liquid is discharged, the gravity applied to the pressure plate 11 will disappear. At this time, the stretched elastic sleeve 21 will use the rebound force to pull the cone plate 20 upward under the support of the tank body 1, so that the cone plate 20 drives the second support ring 34 under the action of the external force, and uses the threaded action of the second support ring 34 and the winding disk 36 to push the winding disk 36 to rotate under the support of the bearing 35, so that the etching liquid wound to the outside of the winding disk 36 can be discharged to the outside of the winding disk 36. The pull rope 42 can be released during the rotation process, and the spring 38 that is pulled and deformed will use its rebound force to push the rotating rod 40 to rotate under the support of the tank body 1 through the baffle plate 39 under the support of the universal wheel 41, so that the rotating rod 40 drives the screw rod 37 to rotate together, so that the screw rod 37 uses the threaded action with the tank body 1 to push the universal wheel 41 downward to approach the transport vehicle. At the same time, the cone disk 20 will drive the connecting disk 22, the connecting plate 23, the fixing plate 24 and the magnet 25 to move upward together, and cooperate with the staff to rotate the bolt 32 to separate the magnet 25 from the transport vehicle.

[0136] Working principle: the storage level of the etching liquid is controlled by the liquid limiting part, which includes a support member and a cover member. The cover member can be raised and lowered and fits with the support member to form a limit on the liquid. When the etching liquid is injected into the inner tank 3, the liquid pushes the cover member to move downward to ensure that the liquid does not exceed the set storage level and prevent the liquid from overflowing.

[0137] When the etching liquid is injected into the tank body 1, the gravity of the liquid pushes the magnetic fixing member down through the linkage, so that the magnet 25 contacts the metal surface of the transport vehicle, and the adsorption force of the magnet 25 fixes the position of the tank body 1 to prevent displacement during transportation, thereby ensuring that the tank body 1 always remains stable during transportation and avoiding danger caused by inertia of the vehicle when driving.

[0138] When the magnetic fixing member descends to fix the tank body 1, the screw 37 cooperates with the rotating rod 40 and the spring 38 to drive the rotating rod 40 to rotate when the winding disk 36 rotates, so that the screw 37 pushes the universal wheel 41 upward to leave the ground. After the tank body 1 is fixed on the transport vehicle, the universal wheel 41 is automatically retracted, avoiding unnecessary rolling of the tank body 1 during transportation.

[0139] When the transportation is completed, the staff can open the discharge valve 8, and the etching liquid is discharged through the discharge valve 8. As the liquid is discharged, the gravity on the pressure plate 11 disappears, and the elastic sleeve 21 returns to its initial position through the rebound force, driving the cone disk 20, the connecting disk 22 and other components to move upward. At this time, the threaded action of the second support ring 34 and the winding disk 36 will also cause the winding rope 42 to be released, and the universal wheel 41 will land again, and the moving function will be restored.

[0140] When it is necessary to release the fixed positioning of the tank body 1, the staff can push the roller 33 down by rotating the bolt 32, and gradually lift the magnet 25 in the magnetic fixer through the friction with the transport vehicle or the ground, so that the magnet 25 is separated from the transport vehicle, and the tank body 1 can resume the mobile state, ensuring the safety, stability and efficiency of the etching liquid during storage and transportation.

[0141] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
