Abstract
The utility model relates to a dustproof flexible connection device, which comprises an inner tube, a sleeve, a filter cloth belt and an outer tube, wherein the outside diameter of the inner tube is less than the inside diameter of the outer tube; the sleeve is fixed on the external circular surface of the inner tube; one end of the inner tube is inserted into the interior of the outer tube; the filter cloth belt is encircled into a filter cloth ring, the diameter of which is slightly more than the outside diameter of the outer tube; and upper and lower ends of the filter cloth ring are respectively fixed on the external circular surfaces of the sleeve and the outer tube. According to the utility model, by adopting the flexible connection structure that the outer tube is sleeved with the inner tube, the interaction effect between the outer tube and the inner tube can be avoided; the measuring precision is increased; flowing materials cannot be directly acted on the filter cloth; the service life of the filter cloth can be effectively prolonged; influence on a measuring scale caused by feeding and discharging devices can be effectively avoided; and the dustproof flexible connection device disclosed by the utility model has the advantages of being simple in structure, high in use reliability and good in dustproof effect and has wide practicability.
Description
Technical field
The utility model relates to a kind of jockey, particularly a kind of dustproof soft connection device that is applicable to each weigher charging aperture of dry-mixed mortar plant and discharging opening.
Background technology
Dry-mixed mortar is by mixing in proportion through each component such as dry sand, cement, flyash and additive after the accurate measurement, and whether accurate measurement has a significant impact the quality of finished product dry-mixed mortar.Also there is following deficiency in the interconnection technique of the bucket body of existing weigher and feed arrangement and drawing mechanism: (1) external device (ED) can produce the active force of uncertainty, randomness to bucket body, so that measure inaccurately, works unreliable; (2) because unreasonable structure, as directly the circulated effect of material of the filter cloth belt that is flexible coupling, be easy to damage.
The utility model content
The purpose of this utility model is the weak point that overcomes in the prior art, and the dustproof soft connection device of a kind of simple in structure, accurate measurement, reliable operation, long service life, good dustproof effect is provided.
For achieving the above object, a kind of dustproof soft connection device of the present utility model comprises inner tube, sleeve pipe, filter cloth belt, outer tube, and the external diameter of inner tube is less than the internal diameter of outer tube, and sleeve pipe is fixed on the periphery of inner tube, and an end of inner tube inserts the inside of outer tube; Filter cloth belt surrounds the filter cloth ring that diameter is a bit larger tham the outer tube external diameter, and filter cloth ring upper/lower terminal is separately fixed on the periphery of sleeve pipe and outer tube.
Beneficial effect: the utility model adopts the structure of outer tube sleeve inner tube, and connect with filter cloth belt between the two, can avoid influencing each other between outer tube and the inner tube, if namely inner tube connects the discharging opening of metering hopper or the charging aperture of external pipe connection metering hopper, then can solve outside device for discharging or feed arrangement to the problem that affects of weigher, improve measuring accuracy; In addition, filter cloth belt places the outer surface of inner and outer tubes, and the material that therefrom flows through can not act directly on the filter cloth, can effectively prolong its service life.It is simple in structure, can effectively avoid charging/discharging device on the impact of weigher, and dependability is high, and good dustproof effect has widely practicality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The 1-inner tube; The 2-sleeve pipe; The 3-filter cloth belt; The 4-outer tube.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Dustproof soft connection device of the present utility model mainly is made of inner tube 1, sleeve pipe 2, filter cloth belt 3, outer tube 4, and the external diameter of inner tube 1 is less than the internal diameter of outer tube 4, and sleeve pipe 2 screw threads are fixed on the periphery of inner tube 1, and an end of inner tube 1 inserts the inside of outer tube 4; Filter cloth belt surrounds the filter cloth ring that diameter is a bit larger tham outer tube 4 external diameters, and filter cloth ring upper/lower terminal is separately fixed on the outer surface of the outer surface of sleeve pipe 2 and outer tube 4.
