Abstract
The utility model relates to a safety protection device of a twin screw machine for a laboratory. The cylindrical body of the traditional twin screw machine can not automatically release pressure, so that materials are probably to burn and explode. The safety protection device of a twin screw machine comprises a cylinder, wherein the cylinder comprises an upper half cylinder and a lower half cylinder which are hinged at one end by a cylinder rotation shaft, the free end of the upper half cylinder is connected with a compression handlebar, the lower end of the compression handlebar is provided with an unlocking spring which is perpendicular to the compression handlebar and is in contact with the compression handlebar, the outer side of the compression handlebar is provided with a hanging hook fixed by a hanging hook rotation shaft, the upper end part of the hanging hook is in contact with the compression handlebar, both sides at the lower end of the hanging hook are respectively provided with a locking spring and a millisecond-level presumption assembly, and the locking spring is transversely arranged at the lower end of the unlocking spring and is in contact with the hanging hook. When the utility model is used in emergency situations, the millisecond-level presumption assembly can pull the hanging hook to move away from the compression handlebar, so that the unlocking spring can automatically open the upper half cylinder to release pressure by means of own elastic force, thereby protecting safety of equipment and personnel.
Description
Technical field
The utility model relates to a kind of dual-screw-stem machine, specifically is a kind of safety guard of dual-screw-stem machine.
Background technology
At present; cylindrical shell in the dual-screw-stem machine both domestic and external all adopts monoblock type cylindrical shell or combined type cylindrical shell; the problem that existing tube structure exists is: safety guard is not set; when polymer in process because local pressure, temperature, moment of torsion etc. all can't be opened release when excessive automatically, thereby cause security incidents such as material burns, blast easily in cylindrical shell.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of safety guard of dual-screw-stem machine, and its cylindrical shell adopts dissection type open-and-close mechanism, and the cylindrical shell that effectively solves existing dual-screw-stem machine can not be opened automatically and the problem of security incident takes place easily.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of safety guard of dual-screw-stem machine; comprise cylindrical shell; it is characterized in that: described cylindrical shell is at one end formed by the cylindrical shell rotating shaft is hinged by first cylindrical shell and second cylindrical shell; first cylindrical shell termination of hinged end is not connected with and compresses handgrip; compress the handgrip lower end and be provided with the vertically disposed release spring that presses with it; compress the handgrip arranged outside by the fixing hook of hook rotating shaft; the upper end of hook with compress handgrip and press mutually; the both sides, lower end of hook are respectively arranged with locking spring and Millisecond is inferred assembly, and the lower end that locking spring is horizontally installed on the release spring presses mutually with hook.
Above-mentioned hook with compress handgrip and contact with the direct rigidity of arcuate version.
The above-mentioned handgrip that compresses is L shaped structure; Hook is and compresses the L shaped structure of falling of handgrip pressing.
Above-mentioned Millisecond is inferred assembly and is connected with computer.
This kind structure of the present utility model, cylindrical shell adopts the split type structure of combination up and down, and press up and down and tighten by release spring and hook, can be in case of emergency, Millisecond is inferred assembly and can be promoted hook and leave and compress handgrip, and the release spring relies on the elastic force of self to realize that first cylindrical shell opens pressure release, the safety of the protection equipment and the person automatically, eliminate the potential safety hazard of screw rod machine when processable polymer, be particularly suitable for the production and processing of inflammable and explosive polymer; Simultaneously, Millisecond is inferred assembly and can be adopted computer to operate control automatically, realizes unmanned operation, and is convenient and swift, and safety saves time.
Description of drawings
Fig. 1 is that the utility model tightens the status architecture schematic diagram.
Fig. 2 is the utility model released state structural representation.
Among the figure, the 1-Millisecond is inferred assembly, and 2-links up with rotating shaft, 3-hook, 4-handgrip, first cylindrical shell of 5-, 6-rotating shaft, second cylindrical shell of 7-, 8-release spring, 9-locking spring.
The specific embodiment
Below by accompanying drawing the utility model is elaborated.
Referring to Fig. 1; Fig. 2; a kind of safety guard of dual-screw-stem machine; comprise first cylindrical shell 5 and second cylindrical shell 7; cylindrical shell rotating shaft 6; compress handgrip 4; hook 3; hook rotating shaft 2; Millisecond promotes assembly 1 and release spring 8 and locking spring 9; one end of described first cylindrical shell 5 and second cylindrical shell 7 is hinged by cylindrical shell rotating shaft 6 and is in the same place; first cylindrical shell 5 ends of hinged end are not welded with and compress handgrip 4; first cylindrical shell 5 is one by 6 rotations of cylindrical shell rotating shaft with second cylindrical shell 7 closures; compress handgrip 4 and be L shaped handgrip; its lower end is provided with release spring 8; release spring 8 is a compressive state; release spring 8 vertically is provided with contact and presses mutually with the lower surface that compresses handgrip 4; the arranged outside that compresses handgrip 4 has hook 3; hook 3 is for L shaped; its upper end with compress handgrip 4 and overlap together mutually; and with the direct rigidity contact of arcuate version; link up with 3 middle parts and be provided with hook rotating shaft 2; hook rotating shaft 2 can 3 be fixed on the outside that compresses handgrip 4 and release spring 8 with hook, and links up with 3 and can realize and compress separating and pressing of handgrip 4 around 2 rotations of hook rotating shaft.The both sides of linking up with 3 bottoms are relatively set with locking spring 9 respectively and Millisecond is inferred assembly 1, wherein locking spring 9 is horizontally installed on the below of release spring 8, the flexible end of locking spring 9 contacts and presses laterally with hook 3 bottoms, the upper end of hook 3 then compresses handgrip 4 mutually down, to compress handgrip 4 be the cylindrical shell of a sealing with first cylindrical shell 5 with second cylindrical shell 7 closures because locking spring 9 power, therefore link up with 3 all the time greater than the power of release spring 8.Simultaneously the Millisecond contact of inferring assembly 1 then be arranged on the other end and and hook 3 between have the space, and Millisecond promotes assembly 1 and can be connected by computer control, and the computer triggering signal gets temperature sensor, pressure sensor, torque sensor by dual-screw-stem machine and provides.
Under the situation of dual-screw-stem machine in operate as normal; if temperature sensor; pressure sensor; torque sensor detects the temperature in the dual-screw-stem machine cylindrical shell; pressure; when moment of torsion surpasses setting value; at this moment; computer can send signal and promote assembly 1 to Millisecond; Millisecond promotes assembly 1 and promotes hook 3 bottoms; 9 phase inboard compression of locking spring; link up with 3 upper ends and compress handgrip 4 by 2 rotation disengagings laterally of rotating shaft; simultaneously; release spring 8 upwards extends under the situation of its elastic force and promotes to compress handgrip 4; first cylindrical shell 5 with cylindrical shell rotating shaft 6 Unscrews with pressure release, protection equipment and the person safety.
