Description

Purified ash conveying device

Technical Field

The utility model relates to a purify grey transport technical field, specifically be a purify grey conveyor.

Background

The calcium carbide production process utilizes lime and coke as raw materials to perform solid phase cauterization reaction in a closed calcium carbide furnace through electric arc heat, a large amount of high-temperature calcium carbide furnace tail gas is generated in the reaction process, the main component of the tail gas is carbon monoxide and contains a large amount of solid dust, and the solid dust is generally called as purified ash. The purified ash has the characteristics of fine granularity, light specific gravity, high viscosity, difficult water dissolution, easy dust raising and the like, so the purified ash is very easy to be blocked in a conveying device, a large amount of nitrogen is lost and wasted, and the purified ash is conveyed too slowly or incompletely. Therefore, people urgently need a purified ash conveying device which is smooth in conveying, not easy to block and capable of saving nitrogen cost for enterprises.

SUMMERY OF THE UTILITY MODEL

For solving the deficiency of the prior art, the utility model provides a technical scheme as follows:

a purified ash conveying device comprises a pipeline blowing-blocking valve, a nitrogen conveying pipe, a fluidization valve, an ash storage tank, a feeding valve, a material blocking valve, a conveying pipe and a bin pump.

The nitrogen conveying pipe is communicated with the conical bottom of the ash storage tank through a pipeline blowing and blocking valve and a fluidizing valve in sequence. The bin pump is positioned below the ash storage tank; the discharge hole of the ash storage tank is communicated with the bin pump through a conveying pipe; the material conveying pipe is sequentially provided with a material stop valve and a material inlet valve.

The working pressure of the fluidization valve is 50-200 Pa; the preferred operating pressure of the fluidizing valve is 60 Pa.

The fluidization valve and the feed valve may be manually controlled by a manual control console.

The utility model avoids the ash purification clamping stagnation caused by insufficient nitrogen pressure by opening the fluidization valve and the feed valve simultaneously; the nitrogen is used in a centralized way, so that the phenomenon of ineffective blowing can be avoided, and the nitrogen cost is saved for enterprises. Because fluidization valve and feed valve and manual control platform electric connection, the utility model discloses can the manual control purify the volume and the nitrogen gas quantity that the ash was carried, avoid extravagant.

The utility model discloses carry smoothly, difficult jamming practices thrift the nitrogen cost for the enterprise.

Drawings

FIG. 1 is a schematic view of a purified ash conveying apparatus;

wherein: 1. a nitrogen conveying pipe; 2. a pipeline blow-blocking valve; 3. a fluidization valve; 4. a dust storage tank; 5. a feed valve; 6. a material blocking valve; 7. a delivery pipe; 8. a bin pump.

Detailed Description

The technical solution in the embodiment of the present invention will be described below with reference to the accompanying drawings.

Referring to fig. 1, the purified ash conveying device comprises a nitrogen conveying pipe 1, a pipeline blowing and blocking valve 2, a fluidizing valve 3, an ash storage tank 4, a feeding valve 5, a material blocking valve 6, a material conveying pipe 7 and a bin pump 8.

The ash storage tank 4 main part is hollow cylinder, and the cylinder below is installed and is bored the end. The nitrogen conveying pipe 1 is communicated with the conical bottom of the ash storage tank 4, and the conical bottom discharge port of the ash storage tank 4 is communicated with the bin pump 8 through the conveying pipe 7. A pipeline blowing-blocking valve 2 and a fluidizing valve 3 are sequentially arranged on the nitrogen conveying pipe 1 from left to right. The fluidizing valve 3 may use a DN50 solenoid valve. A feed valve 5 and a material stop valve 6 are sequentially arranged on the feed delivery pipe 7 from the ash storage tank 4 to the bin pump 8. Wherein the fluidization valve 3 and the feeding valve 5 are electrically connected with the manual center console.

The utility model discloses the theory of operation as follows: after the purified ash enters the ash storage tank 4, the fluidization valve 3 and the feed valve 5 are simultaneously opened, nitrogen is centralized, and the stable state of the purified ash is changed by strong nitrogen flow, so that the purified ash flows out of the conical bottom of the ash storage tank 4, enters the bin pump through the feed delivery pipe 7, and is finally conveyed out by the bin pump. When the weight of the purified ash in the bin pump is too large, the material conveying pipe 7 can be temporarily closed through the material blocking valve 6, so that the purified ash is prevented from being conveyed too much. When the purified ash is not smooth, the fluidization valve 3 can be controlled by the manual center console to be repeatedly opened and closed to fluidize the ash and blow the ash into the bin pump 8, so that the ash can be manually discharged according to the weight of the bin pump, nitrogen loss is not easy to cause, and the purified ash is smoothly conveyed. If there is a small amount of purification ash backward flow nitrogen gas conveyer pipe 1, can control pipeline and blow stifled valve 2 and sweep, prevent that nitrogen gas conveyer pipe 1 from blockking up.
