Abstract
An exhaust ventilator of a concrete mixing plate comprises a main tower body, a transitional feed bin and a powder metering device, and is structurally characterized in that an exhaust passage penetrates through the middle of the transitional feed bin, the upper portion of the exhaust passage is connected with a dust collection bag, the middle portion of the exhaust passage is integrally welded with the transitional feed bin while the lower portion is equipped with a connection hose, the lower end of the connection hose is communicated with a mixer via a mixer casing, the dust collection bag is suspended on a top beam of the main tower body, an induced draft device is arranged on the transitional feed bin, and an exhaust end of the induced draft device extends out of the main tower body. The exhaust ventilator guarantees accurate powder metering, has cost which is only one fifth of that of a forced dust collector, is low in maintenance cost, and is adaptable to occasions with high environment requirements and space limitation.
Description
Technical field
The utility model relates to building machinery, particularly a kind of concrete mixing plant exhaust ventilator.
Background technology
Present common concrete mixing plant exhaust ventilator, its structure mainly adopts the pressure dust collecter, and 14～24 groups of filter cores are contained in this dust collecter inside, and the forced draft machine is equipped with at the top.The sandstone material is delivered in the transition feed bin and the sandstone material is put into from the transition feed bin the process in the mixer at belt conveyor, this blower fan entry into service, air communication is crossed filter core and is drawn out of, dust then be bonded on the filter core or the transition feed bin that drops back in.Force dust collecter in the course of the work since the aqueous vapor when stirring with dust adhesion on filter core, filter core is stopped up easily, therefore to often open loam cake, cleaning and clean filter core is so not only wasted time and energy, and is influenced efficient; In addition, the life-span of filter core is shorter, and price comparison is expensive.
Summary of the invention
The purpose of this utility model is: a kind of concrete mixing plant exhaust ventilator is provided, it can overcome the deficiency of above-mentioned machine, guarantee the accurate metering of each granular material and the dust emission in the control mixing plant main building, raise the efficiency and reduce cost, be specially adapted to the mixing plant environment for use and require than higher and occasions with limited space.
The purpose of this utility model realizes by following approach:
A kind of concrete mixing plant exhaust ventilator, comprise main building body, transition feed bin, powder metering device, its design feature is: the exhaust passage is passed from the centre of transition feed bin, the top of exhaust passage is connected with the cloth bag that gathers dust, and middle part and the weldering of transition feed bin are one, and the connection flexible pipe has been installed in the bottom, connecting the flexible pipe below communicates with mixer by stirring cover, the cloth bag that gathers dust is suspended on the back timber of main building body, and blower unit is installed on the transition feed bin, and it is external that its exhaust end stretches out main building.
Described exhaust passage is passed from the centre of transition feed bin; the top of exhaust passage is connected with the cloth bag that gathers dust; the middle part is one with the weldering of transition feed bin; the connection flexible pipe has been installed in the bottom; connect the flexible pipe below and communicate with mixer, partly add in the storehouse at middle part, exhaust passage and welded the protection liner plate by stirring cover.The sandstone material is thrown in the process of mixer, the moment increasing of mixer internal gas pressure, and a large amount of dust are discharged from the exhaust passage, enter the cloth bag that gathers dust; After the sandstone material had been thrown, the mixer internal gas pressure reduced, and the dust in the cloth bag that gathers dust is back to mixer again.The protection liner plate can guarantee that the exhaust passage is subjected to that the sandstone material impacts also can be durable in use; exhaust passage and the weldering of transition feed bin not only make these equipment installation and transportation convenient for the structure of one; and help the cleaning of exhaust passage; not only improved efficient but also reduced cost; even under the very narrow and small situation of main building body space, this equipment also can be installed and used.
The described cloth bag that gathers dust has skeleton, and the cloth bag that gathers dust is suspended on the back timber of main building body, and the expanding volume of the cloth bag that gathers dust and mixer capacity are complementary.
Described blower unit is installed on the transition feed bin, and it is external that its exhaust end stretches out main building.Start blower unit when machine feeds intake, dust can be drawn.
By the cooperating of the cloth bag that gathers dust, blower unit and exhaust passage, can reduce to the dust in the main building body minimum.
In sum, concrete mixing plant exhaust ventilator of the present utility model is compared with existing concrete mixing plant exhaust ventilator, has following advantage:
Concrete mixing plant exhaust ventilator of the present utility model, result of use is good, is not subjected to the interference of air pressure drastic change in the time of guaranteeing the powder metering, accurate measurement; The cost of this exhaust ventilator has only 1/5th of common pressure dust collecter, and maintaining cost in the future is specially adapted to the mixing plant environment for use and requires than higher and occasions with limited space less than forcing 1/10th of dust collecter.

The specific embodiment
Below in conjunction with embodiment the utility model is described in more detail.
Concrete mixing plant exhaust ventilator as shown in Figure 1, comprise main building body 2, transition feed bin 4, powder metering device 6, its design feature is: exhaust passage 5 is passed from the centre of transition feed bin 4, the top of exhaust passage 5 is connected with the cloth bag 1 that gathers dust, the middle part is one with 4 welderings of transition feed bin, connection flexible pipe 7 has been installed in the bottom, connecting flexible pipe 7 belows communicates with mixer by stirring cover, the cloth bag 1 that gathers dust is suspended on the back timber of main building body 2, blower unit 3 is installed on the transition feed bin 4, and its exhaust end stretches out outside the main building body 2.
Described exhaust passage 5 is passed from the centre of transition feed bin 4; the top of exhaust passage 5 is connected with the cloth bag 1 that gathers dust; the middle part is one with 4 welderings of transition feed bin; connection flexible pipe 7 has been installed in the bottom; connect flexible pipe 7 belows and communicate with mixer, partly add in the storehouse at 5 middle parts, exhaust passage and welded the protection liner plate by stirring cover.The sandstone material is thrown in the process of mixer, the moment increasing of mixer internal gas pressure, and a large amount of dust is 5 discharges from the exhaust passage, enter the cloth bag 1 that gathers dust; After the sandstone material had been thrown, the mixer internal gas pressure reduced, and the dust in the cloth bag 1 that gathers dust is back to mixer again.The protection liner plate can guarantee that exhaust passage 5 is subjected to that the sandstone material impacts also can be durable in use; exhaust passage 5 not only makes these equipment installation and transportation convenient with 4 welderings of transition feed bin for the structure of one; and help the cleaning of exhaust passage 5; not only improved efficient but also reduced cost; even under the very narrow and small situation in main building body 2 spaces, this equipment also can be installed and used.
