[0002] A hydrochloride collection tank is a container specifically designed for collecting and storing hydrochloride solutions. These tanks are commonly used in chemical, pharmaceutical, and laboratory environments. Their design and construction must take into account the chemical properties of hydrochloride and its corrosiveness to materials. When using hydrochloride collection tanks, relevant safety procedures and operating guidelines must be followed to ensure the safety of operators and environmental protection.

[0003] The existing connection structure of some hydrochloric acid collection tanks connects the tank body to the downstream equipment through pipes and flanges. However, during the installation process, in the limited construction space, personnel need to manually lift the connection structure to a suitable height and then connect multiple sets of bolts for positioning and installation. In actual operation, the long-term lifting of the bolt holes will greatly consume the physical strength of the personnel, which will not only consume a lot of labor, but also have a relatively negative impact on the installation efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome existing defects and provide a connection structure for hydrochloric acid collection tanks. This addresses the issue mentioned in the background section where existing connection structures for some hydrochloric acid collection tanks connect the tank body to the downstream equipment via pipes and flanges. During installation, within a limited construction space, personnel need to manually lift the connection structure to a suitable height before connecting multiple sets of bolts for positioning and installation. In actual operation, prolonged lifting of the bolt holes greatly consumes the physical strength of personnel, resulting in significant labor costs and negatively impacting installation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for a hydrochloric acid collection tank, comprising a connection mechanism and a limiting mechanism disposed outside the connection mechanism to temporarily limit the lifting time required for personnel during installation. The limiting mechanism includes clamping rings symmetrically arranged on the outside of the pipe body, with several limiting pins symmetrically arranged on one side of each clamping ring, and telescopic sliding rods fixedly connected to the other side of each clamping ring. Insertion holes are provided inside each clamping ring, and several first screws are threadedly connected between adjacent clamping rings. Nuts are threadedly connected to the outer side of the bottom end of each first screw. Several foot pads are symmetrically arranged outside the clamping rings, and second screws are slidably connected to the inner side of each foot pad. A spring is movably connected to the outer side of one end of each second screw, and a pressure ring is threadedly connected to the outer side of the second screw. A base column is rotatably connected to the outer side of the bottom end of the spring, and a ball bearing is rotatably connected to the inner side of the base column. By inserting limiting pins into several threaded holes in adjacent flanges, the height position of the device can be temporarily limited, facilitating the installation of multiple sets of fixing screws and reducing the time required for personnel to lift the device.

[0006] Preferably, the outer sides of both ends of the pipe are fixedly connected to a transition flange, and the inner side of the transition flange is symmetrically provided with a number of connecting screw holes.

[0007] Preferably, the inner diameter of the insertion hole is larger than the outer diameter of the connecting screw between the devices.

[0008] Preferably, a knob is fixedly connected to one side of the pressure ring, and several knobs are symmetrically arranged. A second screw is threadedly connected to the inner side of the pressure ring.

[0009] Preferably, the foot pads are fixedly connected with reinforcing ribs, and the reinforcing ribs are arc-shaped.

[0010] Preferably, a buffer pad is fixedly connected to the outside of the reinforcing rib, and several buffer pads are symmetrically arranged, and the buffer pads are made of flexible material.

[0011] Preferably, a limiting piece is fixedly connected to one end of the second screw, and the limiting pieces are all located on one side of the foot pad.

[0012] Preferably, a washer is movably connected to the outer side of the tip of the first screw.

[0013] Compared with the prior art, the present invention provides a connection structure for a hydrochloride collection tank, which has the following advantages:

[0014] 1. This utility model features a limiting pin with a clamping ring fixedly connected to one side. Several foot pads are symmetrically arranged on the outer side of the clamping ring. Adjacent foot pads are threadedly connected to a first screw, and a second screw is slidably connected to the inner side of each foot pad. A spring is movably connected to the outer side of one end of the second screw, and a pressure ring is threadedly connected to the outer side of the second screw. A base column is rotatably connected to the outer side of the bottom end of the second screw, and a ball bearing is rotatably connected to the inner side of the base column. Foot pads are slidably connected to the outer side of the base column. Rotating counterclockwise and loosening each of the first screws reduces the force of the adjacent base columns engaging the outer wall of the pipe in the vertical direction. At this time, the springs extend and push the second screws towards the center by squeezing the pressure ring until the ball bearing on the inner side of the bottom end of the base column contacts the outer wall of the pipe. The limiting mechanism, in conjunction with the rolling of the ball bearing and the extension of the telescopic slide rod, allows the pipe to slide to both sides on the outer wall of the pipe. The pipe is then lifted to the height where the connecting bolt hole in the adapter flange is flush with the connecting flange of the hydrochloric acid collection tank and the downstream equipment. Holding the reinforcing rib, the ball bearing on the outer wall of the pipe... Roll and slide the clamping rings to both sides until the limit pin passes through the connecting bolt hole of the adapter flange. Continue to slide the clamping rings so that the limit pin is inserted into the inner wall of the flange bolt hole set at both ends of the equipment. Rotate the first screw clockwise to tighten the clamping rings. The ball is squeezed back into the clamping rings by the outer wall of the pipe body. At this time, the limiting mechanism switches to the state of clamping the outer wall of the pipe body with the clamping rings, and the limiting mechanism is fixed. In this state, the connecting mechanism is limited by the insertion of the limit pin into the bolt hole of the connecting flange of both ends of the equipment, and can be stabilized without personnel lifting. Finally, the limit screw is passed through the insertion hole and threaded to both ends of the equipment to initially fix the device. Reverse the operation to make the limit pin disengage from the occupied bolt hole, and install the limit screw in the remaining bolt hole to completely fix the connecting mechanism and complete the connection between the hydrochloric acid collection tank and the downstream equipment. By inserting the limit pin into the bolt hole of the connecting mechanism and the bolt holes of the hydrochloric acid collection tank and the downstream equipment, the time required for personnel to lift the device can be greatly reduced, thereby effectively reducing the labor input of personnel and ensuring installation efficiency.

[0015] 2. This utility model features a knob with a pressure ring fixedly connected to one side, and a second screw threaded to the inner side of the pressure ring, which allows for convenient and easy manipulation and rotation by personnel.

[0016] 3. By setting up reinforcing ribs, with foot pads fixedly connected to both sides of the reinforcing ribs, and a clamping ring fixedly connected to one side of the foot pads, this utility model can effectively ensure the stability of the foot pads during long-term use.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This utility model provides a technical solution: a connection structure for a hydrochloric acid collection tank, including a connection mechanism 1 and a limiting mechanism 2 disposed outside the connection mechanism 1 to temporarily limit the lifting time required for personnel during installation. The limiting mechanism 2 includes clamping rings 201 symmetrically arranged on the outside of the pipe body 101. Several limiting pins 202 are symmetrically arranged on one side of the clamping rings 201, and telescopic sliding rods 203 are fixedly connected to the other side of the clamping rings 201. Insertion holes 212 are provided on the inner side of the clamping rings 201. Several first screws 204 are threadedly connected between adjacent clamping rings 201. Nuts 205 are threadedly connected to the outer side of the bottom end of the first screws 204. Several foot pads 206 are symmetrically arranged on the outside of the clamping rings 201. A second screw 207 is slidably connected to the inner side of the 6th flange. A spring 208 is movably connected to the outer side of one end of the second screw 207. A pressure ring 209 is threadedly connected to the outer side of the second screw 207. A base column 210 is rotatably connected to the outer side of the bottom end of the spring 208. A ball bearing 211 is rotatably connected to the inner side of the base column 210. By inserting a limiting pin 202 into several threaded holes of adjacent flanges, the height position of the device can be temporarily limited, facilitating the installation of multiple sets of fixing screws and reducing the time required for personnel to lift the device. Rotating counterclockwise and loosening each gasket 7 reduces the force of the base column 210 engaging the outer wall of the pipe body 101 between adjacent base columns in the vertical direction. At this time, the spring 208 relaxes and extends, pushing the second screw 207 by squeezing the pressure ring 209. 07. Move towards the center until the ball bearing 211 on the inner side of the bottom of the base column 210 contacts the outer wall of the pipe body 101. At this time, the limiting mechanism 2, in conjunction with the rolling of the ball bearing 211 and the extension of the telescopic slide rod 203, can slide to both sides on the outer wall of the pipe body 101. Then, lift the pipe body 101 to the height where the connecting bolt hole 103 in the transition flange 102 is flush with the connecting flange of the hydrochloric acid collection tank and the downstream equipment. Hold the reinforcing rib 4 and, through the rolling of the ball bearing 211 on the outer wall of the pipe body 101, slide the clamping ring 201 to both sides until the limiting pin 202 passes through the connecting bolt hole 103 of the transition flange 102. Continue to slide the clamping ring 201 so that the limiting pin 202 is inserted into the inner wall of the flange bolt hole of the equipment at both ends, clockwise. Rotating the first screw 204 tightens the clamping ring 201, and the ball 211 is squeezed back into the clamping ring 201 by the outer wall of the pipe body 101. At this time, the limiting mechanism 2 switches to the state where the clamping ring 201 clamps the outer wall of the pipe body 101, and the limiting mechanism 2 is fixed. In this state, the connecting mechanism 1 is limited by the insertion of the limiting pin 202 into the threaded hole of the connecting flange of the two end equipment, and can be stabilized without personnel lifting. Finally, the limiting screw is passed through the insertion hole 212 and threadedly connected to the two end equipment to initially fix the device. The reverse operation is then performed to disengage the limiting pin 202 from the occupied threaded hole, and the limiting screw is installed in the remaining threaded hole to completely fix the connecting mechanism 1, thus completing the connection between the hydrochloric acid collection tank and the downstream equipment.

[0026] In this utility model, preferably, the outer sides of both ends of the pipe body 101 are fixedly connected with transition flanges 102, and a plurality of connecting screw holes 103 are symmetrically arranged on the inner side of the transition flanges 102. The pipe body 101 is placed between the connecting end flange of the hydrochloric acid collection tank and the connecting flange of the rear equipment. The limiting screws are respectively inserted into the connecting screw holes 103, and the other end is connected to the screw holes of the connecting end flanges of the two end equipment, so as to realize the connection between the hydrochloric acid collection tank and the rear equipment.

[0027] In this invention, preferably, the inner diameter of the insertion hole 212 is larger than the outer diameter of the connecting screw between the devices, so that after the connecting screw is inserted into the insertion hole 212 and connected to the screw holes of the flanges at both ends, the clamping ring 201 can be moved back.

[0028] In this utility model, preferably, a knob 3 is fixedly connected to one side of the pressure ring 209, and several knobs 3 are symmetrically arranged. A second screw 207 is threadedly connected to the inner side of the pressure ring 209, which can effectively and conveniently allow personnel to directly pinch and rotate it.

[0029] In this utility model, preferably, the foot pads 206 are fixedly connected with reinforcing ribs 4, which are arc-shaped structures, and can effectively ensure the stability of the position of the foot pads 206 during long-term use.

[0030] In this utility model, preferably, a buffer pad 5 is fixedly connected to the outside of the reinforcing rib 4. Several buffer pads 5 are symmetrically arranged. The buffer pads 5 are made of flexible material, which can effectively facilitate the sliding of the person after holding them.

[0031] In this invention, preferably, one end of the second screw 207 is fixedly connected to a limiting piece 6, and the limiting pieces 6 are all located on one side of the foot pad 206, which can effectively limit the sliding stroke of the second screw 207.

[0032] In this invention, preferably, a washer 7 is movably connected to the outer side of the top end of the first screw 204, which can effectively ensure the stability of the position of the first screw 204 during long-term use.

[0033] The working principle and usage process of this utility model are as follows: During use, rotating counterclockwise loosens each of the first screws 204, reducing the force with which adjacent base columns 210 engage with the outer wall of the tube body 101 in the vertical direction. At this time, the spring 208 relaxes and extends, pushing the second screw 207 towards the center by squeezing the pressure ring 209 until the ball bearing 211 on the inner side of the bottom end of the base column 210 contacts the outer wall of the tube body 101. At this point, the limiting mechanism 2, in conjunction with the rolling of the ball bearing 211 and the extension / retraction of the slide rod 2... The extension of 03 allows it to slide to both sides on the outer wall of the pipe body 101. At this time, the pipe body 101 is lifted to the height where the connecting bolt hole 103 in the transition flange 102 is flush with the connecting flange of the hydrochloric acid collection tank and the downstream equipment. After holding the reinforcing rib 4, the rollers 211 roll on the outer wall of the pipe body 101, and the clamping ring 201 slides to both sides until the limiting pin 202 passes through the connecting bolt hole 103 of the transition flange 102. Continue to slide the clamping ring 201 so that the limiting pin 202 is inserted into the connecting flange of the two ends of the equipment. The first screw 204 is rotated clockwise to tighten the clamping ring 201, and the ball 211 is squeezed back into the clamping ring 201 by the outer wall of the pipe body 101. At this time, the limiting mechanism 2 switches to the state where the clamping ring 201 clamps the outer wall of the pipe body 101, thus fixing the limiting mechanism 2. In this state, the connecting mechanism 1 is stabilized without the need for personnel to lift it because the limiting pin 202 is inserted into the screw holes of the connecting flanges of the two end equipments. Finally, the limiting screw is passed through the insertion hole 212 and threadedly connected to the two end equipments to initially fix the device. The reverse operation is then performed to disengage the limiting pin 202 from the occupied screw hole and install the limiting screw in the remaining screw hole to completely fix the connecting mechanism 1, thus completing the connection between the hydrochloric acid collection tank and the downstream equipment. By inserting the limiting pin 202 into the screw holes of the connecting mechanism 1 and the hydrochloric acid collection tank and the downstream equipment, the time required for personnel to lift the device can be greatly reduced, thereby effectively reducing the labor input of personnel and ensuring installation efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
