Abstract

The utility model relates to a wooden powder removing device, which is composed of a transmission mechanism and a wooden powder removing device main body, wherein, the wooden powder removing device main body comprises a set of double crank shaft mechanism, an upper shaft and a lower shaft are respectively connected with the double crank shaft through connecting boards, and an upper and a lower sieving boards are respectively arranged on the upper shaft and the lower shaft. The utility model adopts the crank eccentricity to make the upper and the lower sieving boards rotatablely move along the respective shaft and move back and forth so that coal bricks falling on a sieving plane pass through smoothly without being clamped and the coal powder stuck on a sieving strip is automatically removed in order not to be stuck thicker and thicker. The utility model has the advantages of reliable working performance, simple structure, convenient assembly and disassembly, and convenient maintenance. The utility model can automatically remove adhesive objects.

Description

A kind of Wooden screen for removing powder

The utility model is a kind of power plant Wooden screen for removing powder.

Power plant is fully burned in order to make coal, and coal is entered boiler after pulverizer is clayed into power, and coal is in a series of processes such as digging, transportation, pulverizing, and various impurity mix wherein, resemble wooden unit, iron block etc.These foreign material usually block equipment in pulverizer, make the user have to shut down maintenance, and influence is produced.In addition, these foreign material are entrained in the coal, influence the purity of coal, can not correctly measure the caloric value of coal.China adopts in the past asks shape, petal, the peach shape Wood-removing device of plum, and its principle, structure are roughly the same, and the wood effect that removes of these Wood-removing devices is paid no attention to and resembled, and can not guarantee the ordinary production of power plant.

The purpose of this utility model provides a kind of novel Wood-removing device, it to remove foreign material effective, and simple in structure.

The purpose of this utility model is achieved in that it is made up of transmission mechanism and Wooden screen for removing powder main body, it is characterized in that the Wooden screen for removing powder main body comprises a cover hyperbolic axis mechanism, upper and lower axle links to each other with the hyperbolic axle respectively by gusset piece, and upper and lower sieve plate is installed in respectively on the upper and lower axle.

The utility model adopts hyperbolic axle, double-amplitude structure, utilizes the eccentric throw of military handle, makes upper and lower sieve plate do gyration along axle separately, moves back and forth simultaneously.The upper and lower mobile generation of sieve plate was imitated fruit for two kinds, the one, make the coal cinder that drops on the compass screen surface smoothly by and unlikely blocking, the 2nd, give birth to the coal dust that is bonded on the sieve plate to clear up automatically, and be unlikely sticking more thick more, sieve plate reciprocating motion is in the horizontal direction delivered to discharging opening with foreign material such as the iron that cleans out, wood.So the utility model reliable working performance can be removed adhesive automatically, device structure is simple simultaneously, adorns, tears open conveniently, is convenient to maintenance.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done the thin explanation of further rubber.

Fig. 1 is the lateral plan of Wooden screen for removing powder main body of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

1 is to go up axle among the figure, the 2nd, lower shaft, the 7th, the hyperbolic axle, last axle links to each other with the hyperbolic axle by two connecting plates 6, and lower shaft links to each other with the hyperbolic axle by two connecting plates 8, all adopts welding between upper and lower axle and the connecting plate, connecting plate has semi-circular groove, be stuck on the hyperbolic axle, transmission mechanisms such as motor, decelerator drive bent axle and rotate, and drive upper and lower axle by connecting plate simultaneously and make circular motion.Suit between upper sieve plate 4 and the last axle, suit between following sieve plate 5 and the lower shaft, connecting plate 6 and 8 tail end respectively have an

axle

9 and 10, and the tail end of upper and lower sieve plate is set on this axle.3 is hyperbolic axle end bearings among the figure, and transmission mechanisms such as motor, decelerator pass to the hyperbolic axle thus with power, makes it to drive upper and lower axle and upper and lower sieve plate and finishes separately action.

Claims

1, a kind of Wooden screen for removing powder, it is made up of transmission mechanism and Wooden screen for removing powder main body, it is characterized in that the Wooden screen for removing powder main body comprises a cover hyperbolic axis mechanism, and upper and lower axle links to each other with the hyperbolic axle respectively by gusset piece, and upper and lower sieve plate is installed in respectively on the upper and lower axle.
