A kind of screw concrete formula dedusting recovery system
The present invention relates to building dedusting technology field, in particular to a kind of screw concrete formula dedusting recovery system.
As Urbanization in China is constantly accelerated, the development of the engineering projects such as high-speed railway, water conservancy and hydropower has also obtained fast
Speed development, also increasing for the demand of commerical ready-mixed concrete, building of the commerical ready-mixed concrete not only in each big and medium-sized cities in the whole nation is applied
It is widely used in work, and continuous popularization has also been obtained in many small towns, existing concrete mixing plant is generally only small
Scale carries out processing discharge to stirring dust, lacks the recycling to dusty gas, and to the dust removing effects of dust also not
Too preferable, common filter device is difficult to realize hold the thorough dedusting discharge of dusty gas and deduster after a period of use
It easily blocks, it is necessary to be replaced, be that the gas of thorough dedusting easily generates environment certain influence, be unfavorable for concrete stirring
The development for the long duration stood.
The purpose of the present invention is to provide a kind of screw concrete formula dedusting recovery systems to reach stirred to concrete
The centralized processing of dusty gas in journey, effective dust inside recycling dusty gas, solve the discharge of existing concrete mixing plant
The problem of dusty gas filtering is not thorough, environmental pollution is serious, the wasting of resources is larger.
Purpose to realize the present invention, the technical solution used for：A kind of screw concrete formula dedusting recovery system, feature
It is, including mixing drum, cleaner, gather dust cylinder, and the exhaust outlet of the mixing drum is connected with wind turbine, and wind turbine is connected with drying and sets
Standby, the inner cavity of the drying equipment is equipped with pressure sensor and heating coil, is connected between drying equipment and cleaner logical
Tracheae, the snorkel are equipped with pneumatic operated valve, and the air inlet of the cleaner is equipped with baffle, is equipped with vertically in cleaner
Except dirt cup, except spiral plate is connected between dirt cup and the inner wall of cleaner, helical duct is formd between the spiral plate, is removed
The bottom of dirt equipment is connected with the cylinder that gathers dust, and the discharge port of the cylinder that gathers dust is equipped with conveyer belt, the conveyer belt and mixing drum into
Material mouth connects.
Further, the pneumatic operated valve is electrically connected with pressure sensor.
Further, the cylinder that gathers dust is set as back taper structure.
Further, described except deduster is equipped in dirt cup, the deduster is sack cleaner.
Further, the inner wall of the baffle and cleaner is equipped with certain angle.
The invention has the advantages that screw concrete formula dedusting recovery system using the present invention has the following advantages：
1st, the processing that the discharge dusty gas of concrete mixing plant is dried prevents moist dusty gas from easily making cleaner
Deduster the advantages of resulting in blockage；2nd, the bottom of cleaner is connect with the cylinder that gathers dust, and the useful dust of dusty gas is carried out
It recycles, economizes on resources, improve the utilization rate of concrete raw material；3rd, except the outside of dirt cup leads to equipped with screw type dedusting
Road, dusty gas generate multiple impacts inside helical duct, are conducive to detach after larger solid particle is fallen, pass through spiral
Channel is slipped to inside the cylinder that gathers dust, and the smaller particle of remaining dusty gas carries out further adsorbing separation by deduster, reaches
To thorough dedusting effect and the blocking of deduster will not be caused.
Description of the drawings
Fig. 1 is the structure diagram of screw concrete formula dedusting recovery system provided by the invention.
The present invention is described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
Fig. 1 illustrates the structure diagram of the screw concrete formula dedusting recovery system of the present invention, including mixing drum 1, removes
Dirt equipment 9, gather dust cylinder 10, and the exhaust outlet of the mixing drum 1 is connected with wind turbine 3, and wind turbine 3 is connected with drying equipment 6, the drying
The inner cavity of equipment 6 is equipped with pressure sensor 5 and heating coil 4, and snorkel 13 is connected between drying equipment 6 and cleaner 9,
The snorkel 13 is equipped with pneumatic operated valve 7, and the air inlet of the cleaner 9 is equipped with baffle 15, is equipped in cleaner 9 vertical
Except dirt cup 8, except spiral plate 14 is connected between the inner wall of dirt cup 8 and cleaner 9, spiral shell is formd between the spiral plate 14
Channel is revolved, the bottom of cleaner 9 is connected with the cylinder 10 that gathers dust, and the discharge port 11 of the cylinder 10 that gathers dust is equipped with conveyer belt 12, described
One end of conveyer belt 12 is located at the feed inlet 2 of mixing drum 1, and conveyer belt 12 conveys effective dust that deduster 8 filters automatically
To the feed inlet 2 of mixing drum 1, so as to fulfill the recycling of entire concentrated dust collecting system, achieve the purpose that economize on resources.
Pneumatic operated valve 7 is electrically connected with pressure sensor 5, and pressure sensor 5 controls 6 inner cavity of drying equipment by pneumatic operated valve 7
Air pressure, so as to ensure the heating effect of dusty gas, ensure to enter the degree of drying of gas in cleaner 9.
The cylinder 10 that gathers dust is set as back taper structure, and such structure cylinder 10 that is conducive to gather dust falls into the precipitation dust of cleaner 9
Onto conveyer belt.
Except deduster 8 is equipped in dirt cup 8, deduster 8 is sack cleaner, and sack cleaner is compared with electrostatic precipitator energy saving
In terms of emission reduction there is the advantage of bigger, under the increasingly stringenter situation of discharging standards, will be become using sack cleaner
The main selection of dust pollution is controlled, is conducive to improve the dust removing effects of the application.
The inner wall of baffle 15 and cleaner 9 is equipped with certain angle, the baffle 15 at this inclination angle can change gas into
Enter the direction of cleaner 9, gas is made to enter helical duct in rotation status, promotion gas is fully touched with helical baffle 14
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, that is made any repaiies
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
