Description

Coal powder conveyer

A kind of coal dust conveyer relates to the conveyer that contains the loop pulling element and be fixed with a series of impellers on traction element.

The coal dust conveyer is mainly used in the conveying of granular material, carries as the coal dust of coal-fired plant boiler pulverized coal preparation system, also can be used for the conveying of cement, chemical fertilizer, potter's clay etc.Wherein modal is exactly slat conveyer, and it is to utilize sprocket wheel to drive chain and the scraper plate that is fixed on the chain is carried powder.Therefore it is big to have resistance, the big shortcoming of wearing and tearing, and be easy to generate and take off chain, climb the chain phenomenon.For solving this type of deficiency, Chinese patent application has disclosed a kind of " conveyer " for No. 92215474.0, by driving wheel, follower, annular tooth rope and on the tooth rope scraper of band roller constitute.It does not have, and chain rests slippage on the housing, worn-down situation in the embedded scraper transporter, yet this machine also has following deficiency: 1. the scraper plate resistance of motion is big, so the complete machine consumption of current is big; 2. the tooth rope tightens pine down in course of conveying, easily produces chain, floats chain, jumps the chain phenomenon; 3. can not two-wayly carry, degree of utilization is lower.

At above-mentioned deficiency, the purpose of this utility model provides a kind of improved coal dust conveyer, and it can prevent effectively that the tooth rope tightens loose phenomenon down in course of conveying, and transporting resistance is little, degree of utilization is high.

The utility model is achieved by the following scheme: the loop pulling element of being made up of two steel ropes at least is installed in seal casing, and described loop pulling element is by two gear drivens at a distance of certain distance, two motors drive described gear respectively, scraping teeth is fixed on the loop pulling element, and scraper then is fixed on the scraping teeth.When convey materials, the thrust of scraper sense of motion is extruded material, because the constraint of deadweight and two side produces friction force at storeroom, thereby makes material form the state of kinematic motion of continous-stable.

The utility model is owing to adopt steel rope to add the structure of scraper, and therefore resistance in light weight is few, can grow distance and carry.Driven by two motor synchronous simultaneously, solved and tightened down loose phenomenon, can not fall chain, float chain, jump chain, and all right two-way drive of this device, it is low to have an operating costs, economize on electricity durable, maintenance rate is low, advantage that again can continuously-running.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

The coal dust conveyor construction scheme drawing that Fig. 1 the utility model proposes for foundation.

The coal dust conveyer traction element structural representation that Fig. 2 the utility model proposes for foundation.

Coal dust conveyer scraping teeth, scraper assembly relation scheme drawing that Fig. 3 the utility model proposes for foundation.

The coal dust conveyer Guiding wheel structure scheme drawing that Fig. 4 the utility model proposes for foundation.

Below in conjunction with the details of accompanying drawing detailed description according to the coal dust conveyer that the utility model proposes.

This coal dust conveyer includes motor (1), leak free casing (2), as shown in Figure 1.The leak free casing is made by steel plate, and the loop pulling element (3) that is made of two steel ropes at least is installed in casing.Gear (4) is housed at the two ends of loop pulling element, and between gear at a distance of certain distance, and drive the loop pulling element by gear.Electrical motor links with gear behind retarder and two motors link with different gears respectively, drives the loop pulling element synchronously and rotates.Motor, retarder all are fixed on the frame (6), and the axis of two gears is contained on the fixed mount by bearing, and fixed mount (5) then is fixed on the frame.The pulling force of loop pulling element is applied on the frame, and not on casing.Frame then is placed on the track (7), and can be by its position of bolt so that regulate the tightness of annular traction element.

Be fixed with scraping teeth (10) on the loop pulling element of being made up of steel rope (3), be fixed with scraper (11) on the scraping teeth, scraping teeth is the U font together with scraper.Simultaneously, on the loop pulling element, go back fixed interval guide wheel (9) is arranged.The guide wheel pavilion is put on the guide rail (8) that is fixed on the casing, so that support annular traction element.

And for example shown in Figure 2, the scraping teeth (10) that is fixed on the loop pulling element (3) is meshed with gear (4).Therefore when two gears rotate synchronously, can drive the full annular traction element and rotate.Then be fixed with scraper (11) on the scraping teeth, therefore when the loop pulling element rotated, material was subjected to the thrust of scraper sense of motion.Because the constraint of deadweight and two side produces friction force at storeroom, thereby formed the state that continous-stable moves.When fed distance is longer, that is the distance between two gears is when big, and unlikely sagging for making the loop pulling element, fixed interval has guide wheel (9) on the loop pulling element.Guide wheel then is shelved on the guide rail in the casing, thereby can support traction element by guide wheel.In order not influence the forward and reverse of loop pulling element, the groove that is meshed with scraping teeth on the gear (12) is trapezoidal, and it is trapezoidal that the part that scraping teeth is meshed with groove also is.Because in the process of carrying powder, groove might be clogged by powder, so the bottom surface of groove (13) middle part is like the both sides height, so that powder can flow out groove.

As shown in Figure 3, scraper (11) constitutes the U font with scraping teeth (10).Scraper is fixed on the scraping teeth.Scraping teeth is made of two parts, and a part is a tooth, and another part is a pressing plate.The wire rope grip of looping traction element and is fixed by screw rod between tooth and pressing plate.

Fig. 4 is the Guiding wheel structure scheme drawing, and axle one end of guide wheel (9) is fixed on the scraping teeth, and the other end is fixed with wheel shaft retaining ring (14).And horizontal wheel (15) is housed on the wheel shaft retaining ring, in case the capable traction element of stop ring sideslip in use.
