Description

Sand material crushing and circulating system

The technical field is as follows:

the utility model relates to a sand material selects separately the field, specifically says a circulation system is smashed to sand material.

Background art:

in the mortar preparation enterprise, the sand material need be stored in the sand silo after drying, because there is fine material and coarse fodder in the sand material, need separately store, simultaneously, because the use amount of fine material is far greater than the coarse fodder use amount, for fine material and coarse fodder in the balanced supplied materials, need process part coarse fodder into fine material with the rubbing crusher, among the prior art, all separately go on, inefficiency, and the production environment is poor moreover, and the dust is many, causes environmental pollution.

The utility model has the following contents:

the utility model aims to solve the technical problem that a circulation system is smashed to sand material of convenient production is provided.

The technical solution of the utility model is, a circulation system is smashed to sand material is provided, including drum sieve and thin material sand silo, still include the rubbing crusher, first lifting machine and second lifting machine, the drum sieve sets up in the rubbing crusher top, the discharge gate of drum sieve is connected with the feed inlet of thin material sand silo through first lifting machine, the bin outlet of drum sieve is connected with the feed inlet of rubbing crusher through the decurrent row's material pipe of slope, the discharge gate of rubbing crusher passes through the second lifting machine and is connected with the feed inlet of drum sieve, row material pipe upper portion inboard is equipped with hinders formula charge level indicator soon, the row material outside of tubes is equipped with the buzzer siren, buzzer siren is connected with hindering formula charge level indicator soon and is connected, row material pipe upper portion still communicates there is the blast pipe, blast pipe one end is connected with the air-blower, the slope of the blast pipe.

Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: after supplied materials enter the drum screen for screening, qualified fine materials are directly stored in the fine material sand bin through the first lifting machine, coarse materials which do not accord with the fine material standard enter the grinding machine for grinding, then screening is carried out again, qualified fine materials are stored, unqualified fine materials are continuously ground until the fine material standard is met, the whole system is simple in structure, reasonable optimization of relative positions is carried out, contact between dust and ambient air in a conveying link is reduced, in order to prevent blockage of a discharging pipe, coarse materials are mixed into the first lifting machine and are conveyed to the fine material sand bin, a material level meter is further arranged, when the discharging pipe is blocked to a certain height, the material level meter sends an instruction to a buzzer alarm, the buzzer alarm is made to give an alarm, in addition, in order to reduce blockage of the discharging pipe, an air supply device is further arranged, and blockage of the coarse materials can be effectively reduced.

Preferably, a sealing pipeline is arranged outside the first hoisting machine and the second hoisting machine. Reduce dust pollution and form closed transportation.

Preferably, the device also comprises a coarse material sand bin, wherein a feed inlet of the coarse material sand bin is connected with a discharge outlet of the drum screen through a conveying pipe which is inclined upwards, and a switch valve is arranged on the conveying pipe. In actual operation, part of the coarse materials can be screened and stored for preparing mortar.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

the invention will be further explained with reference to the drawings and the detailed description below:

as shown in figure 1, the sand material crushing circulation system comprises a rotary screen 1 and a fine sand bin 2, and further comprises a crusher 3, a first elevator 4 and a second elevator 5, wherein the rotary screen 1 is arranged above the crusher 3, a discharge port of the rotary screen is connected with a feed port of the fine sand bin 2 through the first elevator 4, a discharge port of the rotary screen 1 is connected with a feed port of the crusher 3 through a discharge pipe 6 which is inclined downwards, a discharge port of the crusher 3 is connected with the feed port of the rotary screen 1 through the second elevator 5, a rotary resistance type material level meter is arranged on the inner side of the upper part of the discharge pipe 6, a buzzer alarm is arranged on the outer side of the discharge pipe 6 and is electrically connected with the rotary resistance type material level meter, and is connected with the power supply of the electric cabinet, the upper part of the discharge pipe 6 is also communicated with an air supply pipe 7, one end of the air supply pipe 7 is connected with a blower 8, and the other end of the air supply pipe 7 is obliquely and downwards welded with the discharge pipe in a sealing way. In order to reduce dust generated in the conveying process, a sealing pipeline 9 is covered outside the first lifter 4 and the second lifter 5, namely a pipeline is made of iron sheets, the lifters are accommodated in the pipeline, two ends of the sealing pipeline outside the first lifter are respectively welded on the fine material sand bin and the roller screen in a sealing mode, the sealing pipeline outside the second lifter is respectively welded on the pulverizer and the roller screen in a sealing mode, certainly, the conveying of incoming materials is still carried out according to the existing structure, the incoming materials are conveyed to the roller screen through the lifters, and similarly, a pipeline is arranged outside the lifters and communicated with the sealing pipeline of the first lifter at the feeding port of the roller screen.
