Embodiment 2

[0033] refer to Figure 5 , a water heat treatment device for shale processing, the bottom of the inner wall of the auxiliary chamber 7 is slidingly connected with a connecting ring 19, and a plurality of springs 20 are connected between the bottom outer wall of the connecting ring 19 and the bottom inner wall of the auxiliary chamber 7, and the top of the connecting ring 19 There are grooves 21 distributed in an annular array, and the cross section of the sipe 21 is set in a V-shaped structure.

[0034] When in use, the elastic force of the spring 20 is used to make the air chamber in the auxiliary chamber 7 have a certain range of variation, and the multiple grooves 21 on the top of the connecting ring 19 are used to enhance the cushioning effect of the connecting ring 19, so as to enhance the air pressure in the auxiliary chamber 7. The effect of scatter buffering.

Abstract

The invention belongs to the technical field of shale processing, and in particular, relates to a hydro-thermal treatment device for shale processing; the problem that in the prior art, the hydro-thermal treatment effect is affected by a treatment mode for too large shale hydro-thermal treatment air pressure is solved. Presented are solutions, the hydro-thermal treatment device includes a treatment cylinder; a sealing cover plate is fixed at the top end of the treatment cylinder; a feeding pipe and a liquid discharging pipe are respectively arranged at the top and the bottom of the treatment cylinder; a pressure relief pipe is arranged at the top of the treatment cylinder, a heating piece and a stirring mechanism are arranged in the treatment cylinder, an inner cylinder with an opening inthe top is fixed to the inner wall of the bottom of the treatment cylinder, the top end of the inner cylinder and the sealing cover plate are arranged in a sealed mode, and an auxiliary cavity is formed between the outer wall of the inner cylinder and the inner wall of the treatment cylinder. According to the hydro-thermal treatment device, when the air pressure is increased to exceed the elasticforce of an air spring, a plug body is pressed to one side of the auxiliary cavity, part of the air pressure in the inner barrel is dispersed into the auxiliary cavity from a connecting cylinder, theair pressure in the inner cylinder is reduced, and the hydro-thermal treatment effect is prevented from being affected by too high air pressure in the inner cylinder.

Description

technical field [0001] The invention relates to the technical field of shale processing, in particular to a water heat treatment device for shale processing. Background technique [0002] Shale is a kind of sedimentary rock with complex composition, but all have thin sheet-like or thin-sheet-like joints. It is mainly a rock formed by clay deposition through pressure and temperature, but it is mixed with quartz, feldspar debris and other chemical substances. In order to improve the utilization rate of shale oil production, shale is often hydrothermally pretreated before shale processing operations. [0003] In the process of hydrothermal treatment of shale, the pulverized shale solid is put into the kettle body, and the corresponding reaction melt is added to carry out hydrothermal treatment of shale under high temperature and high pressure. In actual hydrothermal treatment, often with As the reaction progresses, the pressure in the kettle body will increase. In the prior ar...
