Containers such as reaction vessels, storage vessels, and separation vessels are common equipment in the chemical industry. One of the structural types of such vessels is a split structure, which has two parts, the upper part and the lower part. The two parts are connected by flanges and tightened with bolts. Fixed connection. For example, the utility model whose publication number is CN2265069Y disclosed a kind of multi-layer rotating sieve plate type mist flow plant tissue culture container on October 22, 1997, which includes a top cover, a tank body, and a sieve plate net; wherein the top cover, with The tank body and the conical chassis of the rotating sieve mesh are connected together through flanges, gaskets and bolts; the top cover is equipped with an inoculation port with an air inlet and a gas-liquid nozzle device; the gas-liquid nozzle device consists of a gas inlet pipe, a liquid inlet The pipe and the spray head are composed of three parts; the sieve net is uniformly arranged in the tank, and the bottom of the tank is provided with a discharge port near the gas distribution plate; the bottom of the conical chassis is connected to the intake pipe, and the upper part is provided with a gas distribution plate. The side is provided with a liquid outlet pipe from the bottom. The utility model has the advantages of strong practicability, easy enlargement and industrialization, etc., but also has the disadvantage that it takes a long time to disassemble and assemble the bolts. Now in the field of chemical equipment manufacturing, the large-scale equipment is gradually becoming a development trend, and the equipment body is relatively large. Usually, the flange connection will inevitably require more bolts. Generally, the number of flange connection bolts in large containers is often more than 40. Based on the average tightening time of each bolt of 3 minutes, it takes more than 120 minutes to tighten all the bolts. It takes more than 240 minutes to open and close once, and a large-scale production enterprise generally has dozens of equipment, and the comprehensive output loss caused by excessive time-consuming container disassembly and assembly is relatively large every year. If there is a new The fastening method of flange connection can complete a fastening or loosening in a shorter time, which will greatly help improve production efficiency and reduce production loss.

Contents of the invention

In order to overcome the troublesome disassembly and assembly of common flange-bonded split containers and the defects that affect production efficiency, the present invention provides a method that can quickly realize the fastening and loosening of container flanges, thereby greatly reducing the consumption of container disassembly and assembly. When the container is disassembled, it is a quick clamping mechanism for the container that is more convenient.

The technical solution of the present invention is: a quick clamping mechanism for a container, the container includes a bell body and a base that can be separated from each other, the bell body and the base are respectively provided with a bell flange and a base flange, the container The quick clamping mechanism includes a rotatable flange pressing part and a driving device for driving the flange pressing part to rotate. The flange pressing part is sleeved on the junction of the bell body and the base through a flange pressing part support structure. peripheral. The flange pressing part can generate axial extrusion force through circumferential rotation. When the rotating device drives the flange pressing part, the flange pressing part can compress the bell flange and the base flange on the entire outer circumference. , Complete the installation, fastening or unlocking and release between the container bell body and the base in a short period of time. Compared with the traditional flange connection that requires screwing the bolts one by one, the operation is greatly simplified and the work efficiency is greatly improved.

Preferably, the flange pressing member includes a coaxial and parallel clamping ring and a bottom ring, the clamping ring and the bottom ring are fixedly connected, the clamping ring is located above the bottom ring, and the inner circumference of the clamping ring is evenly distributed A number of centripetal clamping ring teeth, which are evenly distributed on the outer circumference of the bell jar flange and have the same number of clamping ring teeth, and can pass through the gap between the teeth of the clamping ring teeth along the axial direction of the base The bottom of each clamping ring tooth and the top of each bell flange tooth are equipped with wedges. The inclined surfaces of the wedges on the bell flange teeth are relatively fit. After the flange of the bell jar and the flange of the base are fitted, if the flange pressing part rotates relative to the bell jar body, the positions of the teeth of the bell jar flange and the teeth of the clamping ring gradually overlap up and down, and the position of the wedges on the teeth of the clamping ring The inclined surface and the inclined surface of the wedge on the bell flange teeth are also gradually fitted, and the pressure between the clamping ring and the bell flange gradually increases. When the flange pressing part turns to the limit position, the upper wedge on the clamping ring teeth The inclined surface of the block and the inclined surface of the wedge on the bell flange tooth reach the maximum. At this time, the clamping ring presses the bell flange to make it closely fit with the base flange, and the bell body and the base enter a locked state. ; Conversely, if the flange pressing part turns over a certain angle relative to the bell body, the bell flange teeth are just staggered from the position of the clamping ring teeth. Through the center, the bell body can be lifted without hindrance and separated from the base.

Preferably, the supporting structure of the flange pressing member is a supporting ring, which is fixed around the outer periphery of the base, the supporting ring is located under the flange of the base, and the flange pressing member is placed on the supporting ring. The support ring provides support for the flange pressing part, so that the flange pressing part can be stably at a height no matter when the bell body and the base are docked or separated, and it is kept in a standby state, so that the bell can be operated at any time. The installation between the cover body and the base is fastened.

Preferably, the bottom ring is located between the base flange and the support ring, and a number of wear-resistant pads are arranged between the bottom ring and the base flange, and the wear-resistant pads are evenly distributed and fixed on the base flange. Wear pad abutment. When the flange pressing part turns to the wedges on the teeth of the clamping ring and the wedges on the teeth of the bell flange engage, the stacked base flange and bell flange are in the gap between the bottom ring and the clamping ring. Under the pair of clamps, the compression force between the base flange and the bell flange comes from the vertical extrusion of the clamping ring and the bottom ring, and this extrusion force is the internal force of the flange compression part system, not It will change the overall stress state of the flange compression parts in the vertical direction. Therefore, the use of flange pressing parts of this structure can simplify the overall structural layout of the equipment, and there is no need to use other structures or devices to provide external forces in the vertical direction to balance the opposing flanges generated when the base flange and the bell flange are pressed. The reaction force of the compression member. Since there is relative displacement between the bottom ring and the base flange when the flange pressing part rotates, wear-resistant pads are set to separate the bottom ring from the base flange to avoid rapid wear.

The clamping ring and the bottom ring are fixedly connected to each other through the connecting ring, and the connecting ring can be processed by integral molding, or cut from a ready-made cylindrical member, and the processing is relatively easy.

As an alternative, several connecting rods are arranged between the clamping ring and the bottom ring, and the two ends of the connecting rods are fixedly connected to the bottom end surface of the clamping ring and the top end surface of the bottom ring respectively. The clamping ring and the bottom ring can also be connected as a whole through a limited number of connecting rods, so that the obtained flange pressing part is lighter as a whole.

As a preference, the mechanism also includes a flange pressing member anti-retraction device, the flange compression member anti-retreat device includes an anti-retreat cylinder and an anti-retreat baffle plate, the anti-retreat cylinder is fixed on the base, and the piston rod of the anti-retreat cylinder A stop pin is fixed on the top, and the stop baffle is fixed on the outer peripheral surface of the flange pressing member. When the piston rod of the stop cylinder is extended, the stop pin abuts against one side of the stop baffle, and Now the top of the backstop pin is higher than the backstop baffle. When the piston rod of the backstop oil cylinder is retracted, the top of the backstop pin is lower than the backstop baffle, and the rotation of the flange pressing piece is not hindered by the backstop pin; when the drive device drives the flange press piece to press the bell jar After the flange and the base flange, the piston rod of the backstop oil cylinder stretches out, the backstop pin blocks the backstop baffle, prevents the flange pressing part from turning, and assists the driving device to keep the bell flange and the base flange stable The compressed state reduces the load on the driving device.

Preferably, the driving device is an oil cylinder, the cylinder body of the oil cylinder is hinged to the base, and the piston rod of the oil cylinder is hinged to the flange pressing member. The oil cylinder has a large output force, stable operation, fast response, and is easier to maintain pressure. It is more suitable for use on larger equipment.

Preferably, there are two oil cylinders at the same height, and the positions of the two oil cylinders are symmetrical about the center of the cross-section of the base at the height where the oil cylinders are located. The oil cylinder group arranged in this way can provide large and stable torque to ensure the rapid and stable rotation of the flange pressing part.

Preferably, a number of balls are embedded on the upper surface of the support ring, the balls are evenly distributed along the circumference of the support ring, and the bottom ring and the support ring are in rolling contact. By embedding balls, a closed rolling path is formed on the upper surface of the support ring.
