Abstract

The invention discloses a reaction vessel. The reaction vessel comprises a reaction vessel body, a vessel cover, a stirring device, a motor, an inlet and a valve at the bottom of the vessel. The stirring device is composed of an agitator arm and agitating blades, wherein one end of the agitator arm is connected to a motor; the vessel bottom is provided with a filter screen, and the filter screen is positioned at the upper part of the valve. The reaction vessel has beneficial effects that solids generated in the reaction process cannot enter the valve at the vessel bottom, large solid particles are blocked on the filter screen, and small solid particles which pass the filter screen are discharged from the valve smoothly, so that the case that the valve is blocked by large particles is avoided, and a good condition is provided for smooth production.

Description

A kind of reactor

Technical field

The invention belongs to chemical industry equipment field, be specifically related to a kind of reactor.

Background technology

In chemical reaction; often there will be the situation of the valve blockage in the exit of Polycondensation Reactor and Esterification Reactor; in chemical process; need to be cleared up by the solid matter obstruction in reaction system if there is the valve at the bottom of reactor still time; just need to first take carrier pipe apart from reactor bottom; open valve; then with sticker, solid matter is smashed to pieces; but often can occur: the moment that solid is smashed to pieces; liquid is gushed; not only cause waste, polluted ground, and be probably sprayed onto on people's body and caused some potential safety hazards.

Summary of the invention

In order to address the above problem, the invention provides a kind of reactor, concrete technical scheme is as follows:

A kind of reactor, comprise the valve at the bottom of reactor body, kettle cover, agitating device, motor, import and still, described agitating device is made up of puddler and paddle, and one end of described puddler is connected on motor, at the bottom of described still, be provided with screen pack, described screen pack is positioned at described valve top.

In this reactor; if the solid producing in course of reaction can not enter into the valve place at the bottom of still; the solid particle of bulk can be trapped on screen pack; even and the solid particle of fritter also can flow out from valve smoothly through screen pack; can not cause the situation of bulk Particle Blocking valve, like this for the good condition that provides is more successfully provided.

Further improve and be: described screen pack is what raise up, middle high, both sides are low.

In this reactor, solid particle can, to the alluvial of screen pack both sides, in the situation that ensureing can not stop up valve, can ensure to be more or less the same before and after circulation, affect circulation, and then reduced operating efficiency otherwise bulky grain gets lodged in meeting on screen pack.

Further improve and be: described reactor main body outside is provided with a chuck layer.

In this reactor, for the reaction of needs heating, add chuck and can be incubated afterwards, save the energy, increase the utilization rate of heat, reduce production costs, be conducive to market competition.

Further improve and be: the top in described reactor main body is provided with the first screen pack, in the middle of described the first screen pack, the porose puddler that supplies passes.

In this reactor, the first screen pack is arranged on the top in reactor, all like this liquid all can be first through the first screen pack, automatically the bulky grain in a upper operation is got lodged on the first screen pack, avoid overstocking of screen pack place solid at the bottom of still, along with the repeatedly impact of liquid, become broken and can pass afterwards, do not affect the utilization to raw material.

Further improve and be: described puddler is provided with multiple paddles.

In this reactor, be provided with multiple paddles, can increase mixing effect, be more conducive to the carrying out of chemical reaction, extraction, washing.

Brief description of the drawings

Fig. 1 is structural representation of the present invention.

Wherein: 1-reactor main body, 2-kettle cover, 3-puddler, 4-paddle, 5-motor, 6-import, 7-valve, 8-screen pack, 9-the first screen pack, 10-chuck layer.

Detailed description of the invention

In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment, only for explaining the present invention, does not form and limits protection domain.

A kind of reactor, comprise reactor body 1, kettle cover 2, agitating device, motor 5, valve 7 at the bottom of import 6 and still, described agitating device is made up of puddler 3 and paddle 4, one end of described puddler 3 is connected on motor 5, at the bottom of described still, be provided with screen pack 8, described screen pack 8 is positioned at described valve 7 tops, described screen pack 8 is what raise up, middle high, both sides are low, described reactor main body 1 outside is provided with a chuck layer 10, top in described reactor main body 1 is provided with the first screen pack 9, in the middle of described the first screen pack 9, the porose puddler 3 that supplies passes, described puddler 3 is provided with two paddles 4.

A kind of reactor that the present embodiment provides, the large-scale particle flowing into because of pressure in still for a upper operation can be trapped on the first screen pack, can not stop up valve; For the solid particle that can produce in reaction, while sinking at the bottom of still, can get lodged on screen pack, and due to gradient, solid particle can be deposited on the both sides of screen pack, not only can not stop up valve, nor can affect the circulation of liquid.

Described chuck can maintain the heat of reaction system as far as possible, increases the utilization rate of heat, has reduced the cost of enterprise.

Two paddles can increase the mixing speed of liquid. For the bulk solid particle situation producing because of local vigorous reaction in some chemical reaction, increase mixing speed and can effectively prevent the generation of bulk solid particle, and be more conducive to the carrying out of chemical reaction.
