Description

A kind of cement bin of mixing plant

Technical field

The utility model relates to a kind of cement bin of mixing plant.

Background technology

Cement bin is the visual plant of often using in the fields such as building concrete mixing plant, and it is a kind of sealingThe tank body of formula, can store a large amount of bulk cement, is generally provided with spiral transferring at the bottom opening place of cement binSend machine, can at any time the cement in cement bin be delivered to the place needing, therefore, cement bin has useConvenient and reliable advantage is the desirable bulk cement storage tank of various mixing plants. Due to the cement of prior artTop, storehouse is only provided with a lid, there is no the effect of dedusting, so this part air tends to take away part placeIn the cement of suspended state, not only cause the waste of cement, and caused environmental pollution. In addition, stirWhile mixing, the resistance in mixer is large, produces steam, and spills the globule, while running into tremie pipe, remains inInside pipe wall, cement can adhere to tremie pipe inwall while entering mixer from tremie pipe, and produces airborne dust, pipe of cementInner more and more narrow, affect the blanking of dry cement, even stop up, after stopping up, cement can not enter mixer.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodimentCase is clearly and completely described, and obviously, described embodiment is only that the utility model part is realExecute example, instead of whole embodiment. Based on the embodiment in the utility model, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to the utility modelThe scope of protection.

As shown in Figure 1, the utility model comprises warehouse 1, anti-block apparatus, deduster and approach switch stop 2;Anti-block apparatus comprises the tremie pipe 4 of inclination, and this tremie pipe 4 is connected to conveying arrangement 3 tail ends, also comprises helix tube10, the charging aperture of helix tube 10 is connected with tremie pipe 4 discharge ends, and the below of helix tube 10 inside is provided with spiralMaterial scraper, described helix tube upper end is provided with the motor 9 that drives material scraper motion, outside helix tube 10 lower endsWall is provided with heater, between tremie pipe 4 and helix tube 10, is flexible coupling. By spiral material scraper, at motorDrive under, each moment all, in the helix tube scraper cleaning to being connected with mixer, makes going out of helix tubeMaterial mouthful keeps clear always, is provided with electric heating tube 11 in helix tube lower end, and heat helix tube lower end,Make the moisture of assembling be able to rapid evaporation. Can evenly drop at transport dress for the ease of the cement in cement binBe set up, cement bin outlet is provided with Arch-Breaking Device, to prevent powder caking, by Arch-Breaking Device, cement bin is exportedCarrying out broken arch, that powder is drawn off is smooth and easy. For the caking that prevents from falling down is fallen into, in agitator 12, to splash new water stickyOn helix tube, under helix tube, be provided with and the inner sloping baffle 13 being connected of agitator, pass through baffle plate13 effect makes the spray splashing be blocked in baffle plate lower surface, has avoided new water to be splashed in helix tube.

Deduster of the present utility model comprises the deduster cylindrical shell 5 that is vertically fixed on warehouse 1 top open part,In this deduster cylindrical shell 5, be horizontally installed with supporting disk 7, on the lower surface of this supporting disk 7, be vertically fixed with multiple removingDirt cylinder 6 (shown in figure is eight) is all enclosed with dedusting filter on the outer surface of each dedusting cylinder 6Cloth simultaneously also has multiple passage (not shown)s on supporting disk 7, like this, when bulk cement byFeed pipe is driven in cement bin, when air is outwards distributed by deduster cylindrical shell 5 places, and these dust removal filter cloth energyEnough will be suspended in airborne cement and adsorb, and avoid cement to be taken out of the outside of cement bin, and air can be byPassage outwards distributes, and has so not only ensured the inside and outside pressure balance of cement bin, can avoid cement simultaneouslyWaste, effectively protected environment. In addition, on the upper surface of supporting disk 7, be also fixed with vibrating motor 8,When absorption on dust removal filter cloth has more cement and while no longer having stronger adsorption capacity, can Vibration on Start-up electricityMachine 8, drives supporting disk 7 and dedusting cylinder 6 constantly to vibrate by it, thereby by the water being adsorbed on dust removal filter clothMud is shaken off down, makes dust removal filter cloth again recover good adsorption capacity.

This practicality is newly provided with square opening at the outer wall of warehouse 1, and square opening position is provided with approach switch stop2, as shown in Figure 2, approach switch stop comprises flange 21, bolt 22, approach switch 23, canvas 24 andIron plate 25, the central authorities of canvas 24 clamp iron plate 25 are set, and four limits of canvas 24 compress by flange 21, and useBolt 22 is fixed on the bulkhead outside of warehouse 1, approach switch 23 be arranged on flange 21 central authorities just to iron plate 25 just beforeSide, and approach switch 23 is electrically connected to controller; When work, when the position of material is lower than canvas 24 centersWhen height in,, canvas 24 is subject to gathering dust negative pressure toward interior movement, and the iron plate 25 at canvas 24 centers is away from approach switch 23,Continue blanking, in the time that the position of material arrives the centre-height of canvas 24, canvas 24 by material 4 toward external pressure, sailThe iron plate 25 at Bu24 center is near approach switch 23, and controller commander stops feeding action, stops blanking.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., allWithin should being included in protection domain of the present utility model.
