Description

Technical Field

[0001] The utility model belongs to the technical field of efficient operation of hydrothermal reaction kettles, and particularly relates to a working device for quickly tightening and opening a subcritical hydrothermal kettle. Background Art

[0002] A hydrothermal reaction kettle, also known as a polymerization reaction kettle, digestion tank, high-pressure digestion tank, high-pressure tank, reaction kettle, pressure bomb, hydrothermal synthesis reaction kettle, digestion tank, hydrothermal synthesis kettle, experimental reaction kettle, etc., is a reactor for material synthesis under certain chemical ratio conditions by adjusting temperature, pressure and filling degree. It is widely used in research and production in departments such as petrochemical industry, biomedicine, material science, geochemistry, environmental science, food science, and commodity inspection. The components of the reaction kettle are divided into a metal outer shell and a lining. The metal outer shell is divided into a kettle cover, a kettle body, a lower gasket, and an explosion-proof sheet (upper gasket). When conducting experiments, it is necessary to tighten the kettle cover and the kettle body. Since the lining of the hydrothermal reaction kettle will expand and contract thermally, it will generate impact stress on the metal outer jacket at high temperatures. When the temperature drops, the expanded lining will shrink, and after the metal outer jacket is loosened by the top, the shrinkage is not synchronized with the lining, resulting in a loosening space, which leads to leakage of the lining solvent and causes experimental failure. Currently, there are usually two methods for tightening and opening the nuts of the hydrothermal kettle. One is manual. This method requires one hand to hold the bottom of the hydrothermal kettle and the other hand to use a metal grip rod to turn the kettle cover at the top of the hydrothermal kettle. It is very labor-consuming, the tightening degree is not easy to grasp, and it is easy to cause harm to the palm. It is time-consuming and laborious and has potential safety hazards. The other is to use a bench vice. It is necessary to clamp the hydrothermal kettle in the opening of the bench vice and then operate with a wrench or a metal rod. The bench vice can only fix one hydrothermal kettle at a time, and each time it is used, it is necessary to adjust the opening of the bench vice to clamp the bottom of the hydrothermal kettle. The operation efficiency is low. Moreover, the contact area between the bench vice and the hydrothermal kettle is small, and it is easy to slip when applying too much force. The efficiency is low and it is not safe. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for quickly and safely tightening and opening a hydrothermal reaction kettle.

[0004] Another purpose of the present invention is to provide a double-layer working device for quickly and safely tightening and opening a hydrothermal reaction kettle.

[0005] Another purpose of the present invention is to provide a double-layer working device for multiple people to operate simultaneously to improve the operation efficiency of the hydrothermal reaction kettle. The double-layer working device for quickly tightening and opening a hydrothermal reaction kettle relying on gravity lever is as follows:

[0006] A double-layer porous array working device for quickly tightening and opening a hydrothermal reaction kettle relying on a gravity lever, comprising a main body workbench surface and a wrench assembly. The main body workbench surface includes a solid metal plate as the lower bottom plate, a metal plate with an array of mounting holes as the operation table surface, and four metal struts as brackets. The metal plate and the metal struts are connected by welding. When using the wrench assembly to unscrew or tighten it, the opening device of the hydrothermal reaction kettle is not prone to sliding and deformation. The wrench assembly includes at least one type of wrench, and the socket hole of the wrench matches the kettle cover of the hydrothermal kettle. The socket hole of the wrench can be in the shape of a round outside and square inside, an open shape, or a square outside and square inside. The bottom of the kettle body of the reaction kettle is fixed to the operation table surface, and a lever structure is formed at the upper end through the wrench assembly. One holds the other end of the wrench to operate.

[0007] For the structure of the double-layer working device, the metal bracket and the metal plate are welded. There is a hollow structure between the lower bottom plate and the operation table surface. The lower bottom plate is a metal flat plate with a certain thickness and weight, which can store the wrench, saving storage space. The whole is stable, not prone to sliding, and not easily deformed by force. Compared with purely manually screwing the kettle to open and close it, it not only realizes the safety and high efficiency of the tightening and opening process, but also achieves labor saving in the tightening and opening process, ensures the continuity of work, and also solves the problem that the impact force generated by the possible residual pressure may push the kettle cover out and cause harm to the palm. It is safe and efficient to use.

[0008] The porous array structure of the double-layer working device is an array of mounting holes arranged in parallel at equal distances. By using the method of laser drilling holes on the operation table surface, multiple equally spaced mounting holes are formed horizontally and vertically. The size of each mounting hole matches the kettle body, and each mounting hole is independent. Multiple reaction kettles can be placed on the operation table at the same time, and multiple people can operate simultaneously, greatly improving work efficiency.

[0009] The two outer ends of the four metal struts of the double-layer working device are ground into semi-circular corners, which are not prone to causing harm to the human body and improve the safety factor.

[0010] For the double-layer working device, a wrench assembly is used, and the kettle body is tightened by leveraging the lever principle. The degree of tightness is easy to grasp, and the experimental accuracy is higher.

[0011] The available materials for the double-layer workbench surface device include various metals or alloys such as stainless steel, aluminum, copper, and iron.

[0012] Regarding the structure of the double-layer workbench device, the lower bottom plate, the operation tabletop, and the four metal pillars are welded to form a spatial structure. The lower bottom plate is used to place heavy objects or for people to step on during operation. During operation, the autoclave body and the work device form an integral whole, and the wrench assembly and the autoclave lid form an integral whole. When the autoclave lid is turned, the heavy object at the bottom and the wrench form a lever. The greater the gravity at the bottom, the more stable the lever. By using the gravity lever to counteract the torsional sliding generated during the operation of the hydrothermal autoclave, the goal of rapid and safe operation is achieved.

[0013] Regarding the structure of the double-layer workbench device, the lower end of the bracket is a metal flat plate with a certain thickness and weight as the lower bottom plate. The friction at the bottom of the bracket is large, and the opening device of the hydrothermal reaction kettle is stable and not easy to slide.

[0014] Regarding the use of the workbench surface, the autoclave body needs to be placed in the installation hole. The installation hole matches the shape of the bottom of the autoclave body, and the autoclave body can be placed in the installation hole without sliding. The wrench assembly and the autoclave lid are slightly larger and match in shape, and can hold the autoclave lid without sliding. During operation, place the autoclave body in the installation hole, and use the wrench to tighten or loosen the autoclave lid. By means of the self-gravity of the work device or the gravity of the heavy object placed at the lower bottom or the gravity of a person stepping on it, multiple autoclaves can be quickly and safely tightened or loosened simultaneously.

[0015] The beneficial effects of the present utility model: Multiple autoclaves can be quickly placed in the installation holes and fixed, and multiple people can operate simultaneously to quickly complete the tightening or loosening of the autoclaves. The work device is stable, with low cost, high efficiency, and convenient use. Description of the Drawings
