Description

I

The invention relates to the industry where there is a need for the separation of fat from water, in particular to the meat industry.

A device for separating fat from water is known, including its sump with a sprayer and a discharge tray located in the upper part, a tank for separating a mixture of grease and water, a device for setting the water level and a fat intake p J.

The drawback of the device is that the fat intake is permanently installed with a gap of 15-20 mm from the level of pure water. This leads to the fact that during operation, when a fat layer is formed, fat is collected not from the upper layers of fat, where high concentration of fat accumulates, but from the bottom adjacent to water. As a result, when the auger operates, the fat enters the intake with a significant admixture of water, which leads to poor quality product selection and the need for subsequent separation of fat from water. In addition, for adjusting the level of the water column, the EQUIPMENT contains an additional capacity with a telescopic tube, which complicates the design.

The purpose of the invention. - selection of fat only from the upper layers and improvement

10 thereby its quality, as well as simplifying the design.

The goal is achieved by the fact that the device for separating the fat from the water, including its septic tank with

15 with a dispenser and an outlet tray located in the upper part, a tank for separating the mixture of fat and water, a device for setting the water level and a fat intake, is equipped with a fire 20, with upper and lower retainers for the fat intake, the latter consisting of a corrugated flexible pipe and a float , but

The lower end of the latrubka is installed below the waterline of the float.

(the device for setting the water level is made in the form of a weir and is located in a tank for separating a mixture of fat and water.

FIG. 1 shows the proposed device; in Fig „2 - section А-А. In fig. one; in fig. 3 — node 1 in FIG. one.

The device consists of a preliminary settler 1. with a sprayer 2 and an outlet tray 3 located in the upper part. The outlet tray 3 connects the preliminary settler 1c with a capacity of g for separating the mixture of fat and water, which is equipped with a spiral-shaped tray (not shown / The fat intake consists of a corrugated flexible pipe 5 and a float 6. The lower end of the pipe 5 is installed mm below the waferline of the 6o float. The float 6 is mounted and can be moved in a vertical plane. These, together with the fat intake, in tank A above the float 6, are an upper limiter 7 of the upper level of fat, which is a sensor, and below the float 6, there is a lower limiter of level 8, which is also a sensor.

The device also contains a device 9 for setting the water level, made in the form of a weir, located in the tank 4 for separating the mixture and water.

The lower parts of the settling tank 1 and the tank h for separating the mixture of fat and water are conical in shape, at the end of which there are valves 10 and 11 connected to pipelines 12 and 13 for draining water. The corrugated pipe 5 is connected to a fixed pipe H, at the end of which a self-priming pump (not shown) is mounted.

The device works as follows.

The device is filled with clear water and a certain level of water is established with the help of the spillway. In this case, the float 6 associated with the fat intake is located in the lower position and the restraint 8 rests. After that, the mixture of fat and water is supplied through the pipeline through the sprayer 2 to the pre-settling tank 1,

89687. four

where the fat floats to the surface of the water and the mixture of fat and water is fed through the bypass tray 3 and the spiral-shaped tray into the container k.

$ The passage through the spiral tray causes the mixture to rotate, with the fat tangential and easy to float on the surface. With the accumulation of fat and

10, the growth of the fat column, which is maintained at a constant level of the water column by means of the weir, the float 6 connected to the corrugated nozzle 5 floats up and, lifting

15 upwardly rests against the stop 7. This automatically switches on the self-priming pump, which extracts fat through the pipeline, due to the fact that the pipe 5 is installed in such a way - that its lower edge is located 3-6 mm below the waterline of the float 6, into the pipe 5 enters a high concentration of fat from the upper layers of the fat column, which

J5 provides high-quality product selection and reduces the cost of additional separation of water from fat. The defatted water is drained through the overflow and the sludge in the lower conical parts of the preliminary sedimentation tank 1 and the tank k through the valves. 10, 11 and pipes 12 and 13 are discharged into the sewer system with water.

As the fat is picked up, float 6,

Linked to the nozzle 5, it lowers and acts on the limiter 8, which disconnects the pump motor. After this, the height of the fat column increases again.

 raising the float 6. The cycle of fat extraction is repeated.

The use of the invention allows to improve the quality of the product selection due to the selection

5 products only from the upper layer of fat, reduce the cost of additional separation of water from fat and improve operating conditions. Moreover, the invention is simple in design.

50 because instead of a complex water level regulator, made in the form of a separate tank with a telescopic tube mounted in it, a device for mounting is installed

55 level of water - made as a simple weir located in a tank for separating a mixture of fat and water.
