Abstract

The utility model provides a reaction kettle for pickling high-purity quartz sand, which is provided with a piston and comprises a kettle body. A heating layer and a heat-insulation layer are arranged on the outer wall of the kettle body, an inner cavity of the kettle body is a piston pressurizing type inner cavity, and the piston is arranged in the inner cavity. Compared with an existing integrated reaction kettle, the reaction kettle for pickling the high-purity quartz sand is provided with the pressure piston, pressure of acid liquor on sand in a pickling process can be increased, accordingly, the permeation efficiency of acid liquor permeating into the sand at the bottom of a tank is increased, a pickling effect is thorough, and the quality and the yield of quartz sand products can be greatly improved.

Description

Agitated reactor is used in a kind of glass sand pickling

Technical field

The utility model relates to a kind of chemical industry equipment, is specially a kind of glass sand pickling and uses the agitated reactor device.

Background technology

The glass sand product (purity>99.99%) be used widely in high-tech areas such as semiconductor, photovoltaic, precision optical instruments; Supply falls short of demand basically for produce market; Domestic production producer is limited by the shortage of high-quality tcrude ore and the bottleneck of quartz sand purification technique mostly, and at present numerous and confused input cost carries out the research and development of Processes and apparatus.

Acid cleaning process is a requisite important step in the glass sand purification process; Its main purpose is to react through impurity in acid solution and the quartz sand to make impurity be able to remove, and the structure of pickling agitated reactor device has determined pickling effect to a great extent, traditional pickling agitated reactor device; It only is a tank body structure of container that machinery is single; Since the grain graininess of glass sand less usually (< 1 millimeter), so can be piled up in the agitated reactor bottom comparatively closely in the acid cleaning process, make acid solution be difficult to effectively infiltrate and contact whole sand grains; Moreover use traditional agitated reactor to carry out the reactive mode that pickling can only take normal temperature to leave standstill; Acid liquid reaction efficient is not high, needs the stand-by period longer, has had a strong impact on the raising of the output and the quality of product.

The utility model content

In order to remedy the technological deficiency that existing pickling agitated reactor exists, the utility model spy provides a kind of glass sand pickling that has piston to use agitated reactor.

Agitated reactor is used in a kind of glass sand pickling, and it comprises kettle, and the kettle lower end is provided with discharging opening, and the kettle outer wall is provided with zone of heating, heat-insulation layer, and the kettle inner chamber is a piston adding pressure type inner chamber, and inner chamber is provided with piston.

Described piston is the agitated reactor end cap, and end cap and inner wall of kettle sealed sliding are dynamically connected, and end cap is connected with pressure actuated device.

Described pressure actuated device is an air cylinder driven, also can be Driven by Hydraulic Cylinder.

Described zone of heating adopts Electric heating.

Kettle is provided with temperature sensor, pressure sensor, is connected with switch board through cable.

Described agitated reactor end cap is withstand voltage, acidproof material.

The beneficial effect of the utility model is: compare existing integral type agitated reactor, the introducing of zone of heating and heat-insulation layer, can so that in the acid cleaning process in the agitated reactor acid solution be in higher temperature all the time, thereby strengthen acid and impurity reactivity, improve reaction efficiency; The introducing of pressure piston can increase in the acid cleaning process acid solution to the pressure of sand body, thereby improves the infiltration efficient of acid solution to the tank base sand body, makes pickling effect more thorough, can significantly improve the quality and the output of glass sand product.

Description of drawings

Fig. 1 is the utility model example structure sketch map.

The specific embodiment

Use agitated reactor like a kind of glass sand pickling shown in the drawings, it comprises kettle 1, and kettle 1 lower end is provided with discharging opening, and kettle 1 outer wall is provided with zone of heating 2, heat-insulation layer, and kettle 1 inner chamber is a piston adding pressure type inner chamber, and inner chamber is provided with piston.

Described piston is an agitated reactor end cap 3 withstand voltage, acidproof material, and end cap 3 is slidingly connected with kettle 1 inner wall sealing, and end cap 3 is connected with pressure actuated device.

Described zone of heating adopts Electric heating, and zone of heating is the heat conduction oil pocket.

Kettle 1 is provided with temperature sensor, pressure sensor, is connected with switch board through cable, is convenient to the staff and monitors the agitated reactor technological parameter.

The course of work of present embodiment is: the quartz sand that will treat pickling drops in the agitated reactor closing presure piston together with acid solution; With agitated reactor zone of heating energising, begin acid solution in the agitated reactor is heated and is incubated, through adjustment heating tape power, acid liquor temperature is stabilized in about 60 ℃ in the control agitated reactor; Open hydraulic press piston is pressurizeed, the piston pressurized progresses into agitated reactor, and air in the agitated reactor and acid solution are continued to exert pressure; Acid cleaning process continues to stop heating after 8 hours, removes piston pressure, and acid cleaning process finishes.
