Gear pump for food processing

Abstract

The invention relates to a gear pump for food processing, which comprises a pump body, an eccentric shaft disk, a chain wheel and a star gear, wherein the left end of the pump body is provided with a feed port and a discharge port which are communicated with a pump cavity, and the right end of the pump body is provided with a pump cover; the eccentric shaft disk is arranged in the pump cavity, the left side of the eccentric shaft disk faces the feed port and the discharge port, the surface of the left side is provided with a crescent block and an eccentric shaft, the eccentric shaft is correspondingly arranged below the concave cambered surface of the crescent block, and the right side of the eccentric shaft disk is provided with a sliding seat; the right side of the chain wheel is provided with chain wheel teeth, the left side of the chain wheel constitutes the back end face of the chain wheel, the chain wheel teeth are matched with the crescent block, the middle of the back end faceof the chain wheel is provided with a chain wheel shaft, and the chain wheel shaft is connected with a power transmission device; and the star wheel is sheathed on the eccentric shaft, and is matchedwith the chain wheel teeth and the crescent block. The invention is characterized in that the sliding seat and the eccentric shaft disk form an integral body. The invention has simplified structure, thereby facilitating manufacturing and avoiding fitting allowance; the eccentric shaft disks have the same concentricity; and the invention embodies the food sanitation and safety.

Description

technical field [0001] The invention belongs to the technical field of food processing machinery, and in particular relates to a gear pump for food processing. Background technique [0002] Gear pumps for food processing are also used to be referred to as star pumps or internal gear pumps for short. As a conveying device for viscous materials, they are used in ice cream machines, jelly machines, and sauce products such as sesame paste, chili sauce filling machines, etc. [0003] Previously, most food processors used plunger pumps to transport materials. Since the plunger pumps move back and forth in the pump body, there is an empty return stroke, so the material transportation is intermittent, which affects production efficiency. Moreover, due to the existence of the empty return stroke, the material in the pump fluctuates periodically, the feeding and discharging speed is unstable, and the phenomenon of more and less occurs, which affects the accuracy of measurement.

AI Technical Summary

Problems solved by technology

On the surface, the cleaning should be thorough, but the actual situation is not like this, because there is usually material between the rear end of the tooth plate 3, that is, the outer wall of the end of the tooth plate 3 without the teeth of the tooth plate, and the wall of the pump chamber. , and it cannot be removed during cleaning, which not only affects hygiene, but also easily damages the gear pump
