Description

Technical Field

[0001] The utility model relates to the technical field of a calorimeter condensate check structure, in particular to a device for preventing the condensate of an adiabatic accelerated calorimeter from flowing back. Background Art

[0002] The accelerating calorimeter is a thermal analyzer based on an adiabatic design. It simulates and measures potential runaway reactions and quantifies the thermal and pressure hazards of certain chemicals and mixtures. To ensure performance, current calorimeters also require equipment cooling components, and the cooling components require the use of condensate, which flows in the pipes to cool the battery.

[0003] To ensure the heating performance, the condensate needs to be collected into the corresponding storage device during the heating process, and then the condensate is transported out through the pipeline. In order to prevent the condensate from affecting the normal heating operation of the equipment, it is necessary to ensure the normal flow of the condensate in the pipeline, and no backflow will occur to affect the normal heating of the equipment. For this purpose, a backflow prevention device is set up. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a device for preventing the backflow of condensate of an adiabatic accelerating calorimeter, comprising a check tube, a pressure reducing column fixedly connected to the middle of the top side wall of the check tube, a conical baffle fixedly connected to the inner wall of the check tube near one end, a blocking column inserted in the baffle, grooves evenly arranged on the inner wall of the blocking column, protrusions fixedly connected to the outer wall of the blocking column, four moving blocks fixedly connected to the outer wall of the blocking column near one end edge, a sliding groove arranged on the side wall of the check tube opposite to the moving block, the moving block is slidably connected in the sliding groove, and an arc structure is established in the middle of one end of the blocking column.

[0005] As a preferred technical solution of the utility model, the inner wall of one end of the check tube away from the baffle is evenly provided with arc grooves, the side wall of the check tube located at the edge of one end of the arc groove is fixedly connected with a spoiler, the spoiler is an inclined structure, the pressure reducing column is a hollow structure and the pressure reducing column is communicated with the inside of the check tube, two semicircular clamps are fixedly connected at both ends of the check tube, the clamps are horn-shaped structures, a tightening nut is provided for rotation outside the clamp, a conical threaded groove structure is provided through the middle of the tightening nut, the tightening nut is threadedly connected to the outer wall of the clamp, the end of the clamp away from the check tube is fixedly connected with a horizontal cross plate, and an inclined sealing gasket is fixedly connected to the bottom side wall of the cross plate.

[0006] As a preferred technical solution of the utility model, one end of the check pipe is detachably connected to a bent pipe by a tightening nut and a clamp, and the bent pipe is a Z-shaped structure.

[0007] The utility model has the following advantages: when backflow occurs, the condensate will impact on one end of the blocking column, and the impact of the condensate will cause a driving force on the blocking column, so the blocking column will be pushed toward the baffle, because the baffle and the blocking column are set up as corresponding conical structures, so when the blocking column is pushed, it will be squeezed and fit on the inner wall of the baffle, so as to achieve a blocking effect, thereby achieving a non-return effect, an arc groove is provided on the inner wall of the non-return tube, and a spoiler corresponding to the arc groove is fixed on the inner wall of the non-return tube, the flowing condensate will flow into the arc groove to form a tributary, which can alleviate the impact force generated by the flow of the condensate, and at the same time, the flowing condensate can be blocked by the established spoiler, and the above two components can effectively reduce the flow rate of the condensate, thereby reducing the impact damage of the condensate on the blocking column, and improving the service life of the equipment, when the condensate impacts the blocking column, it will overflow into the pressure reduction column, thereby further reducing the impact damage of the condensate on the blocking column.

DETAILED DESCRIPTION

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1-3The utility model discloses a device for preventing condensate from flowing back in an adiabatic accelerating calorimeter, comprising a check tube 1, a pressure reducing column 4 is fixedly connected to the middle of the top side wall of the check tube 1, a conical baffle 6 is fixedly connected to the inner wall near one end of the check tube 1, a blocking column 8 is inserted in the baffle 6, grooves 7 are evenly arranged on the inner wall of the blocking column 8, a convex block 9 is fixedly connected to the outer wall of the blocking column 8, four moving blocks 11 are fixedly connected to the outer wall of the blocking column 8 near one end edge, a sliding groove 10 is arranged on the side wall of the check tube 1 opposite to the moving block 11, the moving block 11 is slidably connected in the sliding groove 10, and an arc structure is set in the middle of one end of the blocking column 8;

[0014] The inner wall of the end of the check tube 1 away from the baffle 6 is evenly provided with arc grooves 12, and the side wall of the check tube 1 at the edge of one end of the arc groove 12 is fixedly connected with a spoiler 13, and the spoiler 13 is an inclined structure. The pressure reducing column 4 is a hollow structure and the pressure reducing column 4 is communicated with the inside of the check tube 1, and two semicircular clamps 3 are fixedly connected at both ends of the check tube 1. The clamp 3 is a trumpet-shaped structure, and a tightening nut 2 is set outside the clamp 3 for rotation. The tightening nut 2 has a conical thread groove structure running through the middle, and the tightening nut 2 is threadedly connected to the outer wall of the clamp 3, and the end of the clamp 3 away from the check tube 1 is fixedly connected with a horizontal cross plate, and the bottom side wall of the cross plate is fixedly connected with an inclined sealing gasket.

[0015] The technical effect of this solution is that the check tube 1 is connected to the condenser and the bent pipe 5 by tightening the nut 2 and the clamp 3, and the liquid in the condenser is transported out normally through the check tube 1. When backflow occurs, the arc groove 12 and the spoiler 13 can block the backflowing condensate and reduce the flow rate and pressure of the backflowing condensate. Then, the condensate with reduced flow rate impacts the blocking column 8, which pushes the blocking column 8 to move and blocks the blocking column 8 in the baffle 6, effectively preventing the condensate from affecting the normal operation of the equipment due to the backflow.

[0016] One end of the check tube 1 is detachably connected to the bent tube 5 by means of a tightening nut 2 and a clamp 3. The bent tube 5 is a Z-shaped structure. The end of the check tube 1 away from the bent tube 5 is detachably connected to the end of the condenser tube by means of a tightening nut 2 and a clamp 3. A conical pressure column 14 is fixedly connected to the vertical inner wall of the bent tube 5. The transverse inner wall of the bent tube 5 is evenly provided with flow-blocking grooves 15, which are inwardly recessed structures.

[0017] The technical effect of this scheme is that the Z-shaped structure of the bent pipe 5 can increase the formation of condensate, and can increase the difficulty of the return condensate flowing under the action of weight, thereby improving the check effect, and the established flow blocking groove 15 can block the return condensate, and the pressurizing column 14 is a conical structure. When the return condensate flows to the pressurizing column 14, the condensate can be blocked by the pressurizing column 14. In order to avoid excessive accumulation of condensate causing excessive pressure in the check pipe 1 and causing damage to the bent pipe 5, a hole is opened in the middle of the pressurizing column 14, and the condensate overflows from the hole to reduce the pressure in the bent pipe 5.

[0018] Specifically, when the utility model is used, the two ends of the check tube 1 are respectively inserted into the end heads of the condenser and the elbow 5, and then the tightening nut 2 is rotated. As the tightening nut 2 rotates, the tightening nut 2 can be driven to move through the principle of threaded connection. As the tightening nut 2 moves, the clamp 3 can be pressed. The pressed clamp 3 will squeeze the end heads of the condenser and the elbow 5 to ensure the stability of the connection of the check tube 1. The sealing gasket can increase the sealing performance of the connection between the check tube 1 and the pipeline, and the leakage of condensate can be effectively prevented. The pressurized column 14 can reduce the inner diameter of the elbow 5, thereby increasing the flow pressure and thus increasing the flow rate. The spoiler 13 can also have the same effect, thereby increasing the condensate transportation efficiency and increasing the operating efficiency of the calorimeter.

It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
