Description

A kind of automatic separation equipment and separation method in food industry

technical field

The invention relates to the field of solid-liquid separation equipment, in particular to an automatic separation equipment and separation method in the food industry.

Background technique

The automatic separator is suitable for the separation of liquid and solid particles, especially plays a very important role in removing solid impurities contained in liquid. However, the structure of the traditional separator is relatively complicated, and the separation is not thorough enough. The separated solid impurities need to be cleaned manually after shutdown, which not only affects the separation efficiency, but also has a high labor intensity for workers.

Contents of the invention

Aiming at the deficiencies of the prior art, the invention provides an automatic separation equipment for the food industry, which has a simple structure and can automatically collect and discharge solid separations.

The present invention is achieved through the following technical scheme. It provides an automatic separation equipment for the food industry, which includes a cylinder body with a feed inlet on the top cover, and a screw with a discharge end located outside the cylinder body is pierced on the cylinder body. Conveyor, the feed inlet of the screw conveyor is located in the cylinder and is fixed with an inclined filter screen, the filter screen is arranged along the circumference of the feed inlet of the screw conveyor and forms a wedge shape with a large top and a small bottom. The upper edges of the upper edges are respectively arranged in close contact with the inner wall of the cylinder, and a feed pipe is fixed in the feed inlet, and the lower end of the feed pipe is at least divided into two branch pipes extending to the top of the filter screen.

The filter screen of this scheme is installed obliquely, the feed pipe extends above the filter screen, the liquid flowing in from the feed pipe penetrates the filter screen and falls into the cylinder, the solid matter is blocked by the filter screen and separated from the liquid, and is inclined along the slope The filter screen is rolled into the screw conveyor, collected by the screw conveyor and sent out of the cylinder to complete the filtration and solid separation; the filter screen is surrounded by a wedge shape, the upper port is close to the cylinder, and the lower port is adapted to the feed port of the screw conveyor , to ensure that the solid separator blocked by the filter screen completely falls into the screw conveyor to prevent the solid separator from being mixed into the liquid again; each branch pipe corresponds to a filter screen, which can greatly improve the filtration and separation efficiency.

As an optimization, the pipe wall of the branch pipe is provided with several filter holes along the length direction, and the lower end of the branch pipe is located at the front side or the rear side of the upper end of the branch pipe in the length direction of the filter screen. Through the filter holes set along the length direction, when the oil flows through the branch pipe, it flows out through the filter hole, and the oil residue falls from the end of the branch pipe, and the lower end and the upper end of the branch pipe are staggered along the length direction to avoid oil flowing down from the filter holes on the branch pipe. The liquid is mixed with the oil residue flowing out from the lower end of the branch pipe, which improves the filtration efficiency and shortens the filtration time.

As an optimization, there are two branch pipes arranged in a herringbone shape. The branch pipe setting of this optimization scheme makes the lower ends of the branch pipes face the filter screens on different sides respectively, which improves the utilization rate of the filter screen and ensures the filtering effect.

As an optimization, the blades of the screw conveyor are set with variable pitch, and the casing of the screw conveyor is provided with filter holes. In this optimization scheme, through variable pitch settings, the solid separator entering the screw conveyor is extruded, and the liquid absorbed by the solid separator is extruded, and the extruded liquid enters the cylinder through the filter hole, and the extruded solid separator It is sent to the outside of the cylinder by the screw conveyor, so that the solid-liquid separation is more thorough, and the waste of liquid is reduced.

As an optimization, a coiled pipe is fixed inside the cylinder, and the inlet and outlet of the coiled pipe communicate with the outside of the cylinder. This optimization scheme makes the separator more widely used. If the temperature of the filtered liquid is high, the heated object can be passed into the coil to make full use of the heat contained in the liquid; if the filtered liquid needs to be heated, it can be Heating is carried out by passing high-temperature medium into the coil.

As an optimization, a stirring device extending into the cylinder is also fixed on the cylinder. In this optimization scheme, regardless of whether the liquid in the cylinder is used as a heat source or as a heated object, the stirring device is used to stir the liquid in the cylinder to make the temperature of the liquid in the cylinder consistent in a short time and improve the heat exchange efficiency.

As an optimization, the top cover is stepped, and the part of the top cover opposite to the feed inlet of the screw conveyor is higher than the rest. On the one hand, the position of the edge of the filter can be raised to make the inclination angle larger, and the solid separator can be used to roll off;

As an optimization, it also includes a control system, and a liquid level gauge and a temperature sensor installed on the barrel and electrically connected with the control system. Receive liquid level and temperature signals through the control system, which is convenient for automatic control.

An automated separation method for the food industry:

(1) The oil to be filtered is injected into the feed pipe, which is branched into left and right branches through the lower end of the feed pipe. After being filtered by the filter screen, it enters the cylinder, and the solid separated by the filter screen rolls down along the surface of the filter screen under the action of its own weight and falls into the screw conveyor through the feeding port. When the oil flows through the branch pipe, part of the oil is filtered. The oil residue falls from the end of the branch pipe to the surface of the filter screen.

(2) Start the screw conveyor, and send the solid separation that enters the screw conveyor to the outside of the cylinder. When conveying the solid separation, use the variable pitch setting of the helical blade to squeeze out the oil absorbed in the solid separation. The oil leaks through the filter holes on the shell of the screw conveyor.

(3) Collect the solid separation at the discharge end of the screw conveyor.

By using the method for oil filtration, there is no need to manually clean the solid separation on the filter screen, which reduces labor intensity, realizes centralized collection of solid separation, avoids environmental pollution, and greatly improves the efficiency of solid-liquid separation.
