Detailed Description
The technical solution of the present invention is further explained with reference to the following embodiments.
As shown in fig. 1 and 2, the flotation machine of the present invention includes a water tank 1 disposed obliquely and an auger installed inside the water tank 1. The water tank 1 is in a strip shape, the tank bottom 7 is obliquely arranged, the tank edges at two ends of the strip comprise an upper tank edge 4 and a lower tank edge, wherein the bottom of the upper tank edge 4 is higher than the bottom of the lower tank edge 5; the feed hopper 2 is arranged at one end of the lower groove edge 5; a discharge hole 10 is arranged below the tank bottom 7, water 3 is contained in the water tank 1, and the water surface height is lower than the height of the discharge hole 10, so that the material at the discharge hole 10 enters the next link after being drained.
The auger is also called a screw conveyor and comprises a power device 18, a rotating shaft 9 and blades 8. According to the working mode, the packing auger is divided into horizontal transmission, inclined transmission and vertical transmission, and the working distance can reach tens of meters. The working principle is that when the rotating shaft 9 rotates, the materials move forwards along the bottom of the conveyor under the pushing of the blades 8 by means of the gravity of the materials and the friction force generated between the materials and the wall of the groove body, and the rotating spiral blades push the materials to convey the materials.
The utility model discloses an auger pivot 9 is on a parallel with tank bottom 7 setting and fixed on lower groove limit 5, and power device 18 includes motor and reduction gear. Under the action of the power device 18, the material put in from the feed hopper 2 at one end of the lower groove edge 5 is conveyed to the discharge port 10 at one end of the upper groove edge 4 by the auger and conveyed to the next working procedure through the conveyor belt 13 arranged at the lower end of the discharge port. The feed hopper 2 is composed of an inclined plate 6, a lower groove edge 5 and a side groove edge 21, is of a structure with a large upper opening and a small lower opening, and is convenient for materials to be poured out from a previous large-caliber device and enter the designated position of the auger through a small opening. In order to prevent the water in the groove from flowing out through the gap of the rotating shaft, a commercially available rotary sealing ring 17 is arranged between the rotating shaft 9 and the lower groove edge 5, belongs to one type of dynamic seal, and consists of a sliding ring filled with polytetrafluoroethylene and a rubber O-shaped sealing ring providing elasticity, is used for sealing a rotating rod or shaft and can bear certain lateral pressure.
Generally, the crushed construction waste powder comprises heavy crushed stone, crushed brick material, soil, light plastic, wood dust and the like, and the soil, the light plastic and the wood dust need to be removed in the raw material screening step in the preparation of the water permeable brick, so that the quality of the finished pressed brick in the later period can be ensured. In the figure 1, when a mixture containing light materials and heavy materials enters the front end (namely the feeding end) of an auger arranged below the water surface through a feeding hopper 2, the mixture is conveyed to the rear end (namely the discharging end) of the auger through the rotation and friction action of an auger blade, wherein the light materials are scattered and float on the water surface under the stirring action to conveniently realize manual or mechanical cleaning, the heavy materials are conveyed to a conveying belt below a discharging port under the action of the auger and conveyed to the next link, and because the height of the discharging port 10 is higher than the water surface in a groove, the auger is longer, the water-containing materials are actually in a draining state at the rear end of the auger, and the water content of the materials reaching the discharging port can be effectively reduced. In addition, the soil mixed in the construction waste is dissolved in water, so that the materials leaked from the discharge port are all required crushed stone, crushed brick and the like, and the quality of pressed brick products is ensured. The muddy water in the tank can be changed periodically according to the turbidity condition, and the muddy water can be drained through a drain valve 19 arranged at one end of the tank bottom 7 close to the lower tank edge 5 or pumped out by a water pump for replacement.
As shown in fig. 1 and 2, the entire sink 1 is mounted on a bottom plate 15. The groove bottom 7 is fixed on the bottom plate 15 through the bracket 14, the power device 18 is installed on the fixed seat 16, and the fixed seat 16 is welded on the bottom plate 15. The inclination angle of the rotating shaft 9 of the packing auger, namely the included angle between the rotating shaft 9 and the horizontal plane is 20-50 degrees, and the preferred inclination angle is 30 degrees.
As shown in fig. 3, the cross section of the water tank 1 is a semi-circular arc shape, and the radius of the water tank is matched with the dimension of the auger blade. Compared with the traditional water tank with a square cross section, no dead angle is left at the bottom of the water tank in the rotary conveying process of the packing auger, so that materials entering the water tank from the feeding hole can be conveyed to the discharging end by the packing auger. The distance between the blade and the bottom of the groove refers to the parameters of a conventional auger so as to meet the requirement of conveying powder with conventional granularity.
The utility model discloses based on auger and slope basin structure, one set of equipment realizes the sorting of three kinds of material materials in the building rubbish, and equipment can be in succession function on follow-up brickmaking production line, has simple structure, with low costs, efficient characteristics, and market prospect is wide.
