This invention relates to a Dry Running Flexible Impeller Pump and Method of Manufacture that is specifically designed to provide a flexible impeller pump that is capable of being run dry for extended periods of time without damaging the impeller. The pump's housing and end plates are coated with a low friction industrial coating to limit the heat of friction created by the flexible impeller while in use. Additionally the flexible impeller is cast from a pre-molding silicone substrate that contains no mold release and is cast in a mold that is treated with a low friction industrial coating and is cast without mold release. Once the flexible impeller is removed from the mold it is cleaned with alcohol, baked in a vacuum at a temperature of at least 100° C., and then coated with a Paralene N coating by vacuum deposition.

A paintball loader has a motor-driven impeller with a plurality of resilient arms that engage and move paintballs in the loader housing. The resilient arms preferably are spaced to accommodate paintballs therebetween. The arms are sufficiently flexible to yield so as not to rupture the paintball shells.

The invention discloses a mussel shell removing machine which belongs to shell removing machines. The mussel shell removing machine comprises an opening extension box, a shell removing box and an oscillating screen, wherein the lower part of the opening extension box is provided with a transmission belt; the lower part of the transmission belt is provided with the shell removing box; the lower part of the shell removing box is provided with the oscillating screen; the top of the opening extension box is provided with a feed opening, and the inner part is provided with a flexible impeller; theflexible impeller is connected with a first motor; four symmetrical brushes are arranged in the shell removing box; convex groove plates are respectively arranged between the two brushes at the upperpart and both sides of the two brushes at the lower part; uneven objects are arranged on the convex groove plates; the oscillating screen is connected with a screen frame by a cranked lever; the upper part of the oscillating screen is connected with the screen frame by a support tension spring; a plurality of screen holes are arranged on the oscillating screen; and the brushes, the oscillating screen and the transmission belt are respectively connected with a second motor. The mussel shell removing machine has the characteristics of realizing automated production, solving the problems of mussel extrusion, and the like due to labor force shortage in the producing process of mussels, and the like.

The invention relates to a flexible impeller of an airlock device of a soldering flux recycling machine, comprising an impeller shaft, a first wheel disc, a second wheel disc and a plurality of blades, wherein the first wheel disc and the second wheel disc are fixedly connected on the impeller shaft; and the plurality of blades are arranged between the first wheel disc and the second wheel disc. The flexible impeller of the airlock device of the soldering flux recycling machine is characterized in that the impeller shaft as well as the first wheel disc and the second wheel disc are made from metal to form a metal impeller framework; a flexible colloid cladding layer is arranged on the outer surface of the metal impeller framework; and the blades are made from the flexible colloid. In the invention, the metal impeller framework is adopted for the impeller to ensure the strength and the rigidity of the impeller; and the flexible colloid cladding layer outside the metal impeller framework and the blades made from the flexible colloid can be both deformed, thereby the phenomena of jamming and blocking by large-particle materials do not occur, and the airlock device is safe and reliable to run.

The invention discloses a pump impeller press mounting device in the pump processing technology field, and a press mounting method thereof; the pump impeller press mounting device is provided with a support plate and is characterized in that four guideposts are arranged on the support plate; a support spring is sheathed at the external part of each guidepost; locating plates are sheathed on the guideposts; the support springs are positioned between the support plate and the locating plates; the central position of the support spring is fixed with a locating block; the center of the locating block is provided with a flexible impeller positioning core axle; the central position of the locating plate is provided with a communicating pore and the impeller can pass through the communicating pore; the locating plate is provided with two positioning pins; positioning holes which are matched with the positioning pins are arranged on a pump component; the matching of the positioning pins and the positioning holes, and the matching of the end face of the pump component and the upper face of the locating plate form one-face two-pin positioning and cause the center of the pump component and the flexible impeller positioning core axle mechanism to be concentric. Compared with the prior art, the invention has compact structure, easy operation and high production efficiency, causes the impeller and a rotating shaft to be assembled accurately, and saves the manufacturing cost of a fixture.
