Description

 The invention relates to the integrated processing of fried industrial stocks of food industry enterprises and can be used to purify water from oil and fat products.

 A device for cleaning water from grease products [1] includes a housing with a coaxially located flotation chamber in it, an annular chute for bleeding clarified water with an overflow wall and an opening for the weir in its lower part. The drainage channel for clarified water is located around the perimeter of the device casing from the outside. An overflow wall is installed in the central part of the gutter and serves to adjust the water level in the device. The overflow wall consists of two parts of the lower fixed annular, rigidly attached to the bottom of the gutter, and the upper part mounted on it, divided into separate segments, mounted on the lower part using bolted connections. If necessary, the water level in the device is adjusted by changing the location of both parts of the overflow wall relative to each other after relaxation and re-tightening of the bolted joints.

 The device also includes a pocket for collecting fat products, located in the upper part of the chamber with a side opening for fat discharge, made 2 3 cm above the edge of the overflow wall that defines the mirror for draining the water in the device.

 A disadvantage of the known device is the failure of the bolted joints of the movable and fixed parts of the overflow wall with fluctuations in the pH of the treated water. This prevents the operational regulation of the operation of the device by the moving part of the overflow wall. In addition, the absence of any direct adjustment of the level of grease prevents the operational management of the device in terms of removing extracted fat.

 The closest to the proposed technical essence and the achieved result is a device for purifying water from fat products [2] including a housing with a flotation chamber coaxially located in it, an annular trench for bleeding water with an overflow wall and a spill hole in its lower part. The device also contains a pocket for collecting fat products.

 An overflow wall is installed in the central part of the gutter, serves to adjust the water level in the device and consists of a fixed lower part, rigidly fixed to the base of the gutter, and a movable upper part, mounted on the bottom by means of bolt connections, which allow changing the height of the spillway if necessary by changing the position segments into which the upper part of the overflow wall is divided.

 A pocket for collecting grease products is located in the upper part of the chamber and is equipped with an adjustable slide that forms the overflow edge of the grease discharge, located above the edge of the overflow wall of the outlet for clarified water. The gate consists of a lower fixed part, rigidly fixed to the base, and a pocket near its side wall, and an upper part, mounted on the bottom with bolt connections, which allow changing the height of the grease if necessary.

 The disadvantage of this device is the fastening of the upper movable part of both the overflow wall and the gate to the lower, fixed, bolted connections. To adjust the drain level by changing the position of the movable part, it is necessary to loosen the bolted joints, which is associated with significant labor costs, especially in conditions of partial or complete corrosion of the bolted joints due to changes in the pH of the medium. This leads to the difficulty of operational adjustment of the ratio of the level of discharge of water and fat of the known device.

 Under conditions of a variable load on the device for water purification according to the content of technical fat and productivity, this leads to a partial ingress of purified water into grease and technical fat into purified water, which reduces the efficiency of the device.

 The basis of the invention is the task of increasing the efficiency of water purification by providing operational adjustment of the level of grease and weir of the device.

 The problem is solved in that in a device for purifying water from grease products, including a housing with a flotation chamber coaxially located therein, an annular chute for bleeding clarified water with an overflow wall and a drain hole in its lower part, a pocket for collecting grease products with an adjustable gate forming the grease discharge overflow edge located above the edge of the overflow wall of the clarified water drain chute, the clarified water drain chute is located around the perimeter of the device’s casing from the outside and is equipped with an adjustable gate mounted on an overflow wall in which rectangular holes and grooves are made, a rectangular hole and grooves are made in the side wall of the pocket for collecting grease products, and the gates are made in the form of several patch strips installed in grooves and overlapping rectangular holes with the formation of overflow the edges of the trench drainage clarified water and grease.

 In the overflow wall of the gutter of the drainage of clarified water, the holes are made around the perimeter and the length of each is 10-15% of its diameter.

 The presence of rectangular openings and grooves in the overflow wall of the clarified water gutter and in the side wall of the pocket for collecting grease products and the execution of gates in the form of several patch strips installed in the grooves and overlapping rectangular openings with the formation of overflow edges of the gutter of bleached water and grease discharge allowed provide operational adjustment of weir and grease levels.

 The length of one hole in the overflow wall of the drain of the clarified water, equal to 10-15% of its diameter, is selected based on the fact that the diameter determines the curvature of the circumference of the overflow wall, and the latter determines the possibility of a rectangular patch strip to overlap a segment of the corresponding length of this perimeter.

 In FIG. 1 schematically shows a device for water purification, a longitudinal section; in FIG. 2 shows the node I in FIG. 1; in FIG. 3 is a view along arrow A in FIG. 2.

 The proposed device comprises a housing 1 with a flotation chamber 2 coaxially located therein, an annular groove 3 for bleeding clarified water with an overflow wall 4 and a spill hole 5 in the lower part of the groove 3. The device also includes a pocket 6 for collecting grease products with an adjustable slide 7 forming an overflow edge 8 grease. Grease overflow edge 8 is placed above the edge 9 of the overflow wall 4 of the trough 3 of the drainage of clarified water. The clarified water discharge chute 3 is located around the perimeter of the device body 1 from the outside and is equipped with an adjustable gate 10 mounted on the overflow wall 4, in which rectangular holes 11 and grooves 12 are made. A rectangular hole 14 is made in the side wall 13 of the pocket 6 for collecting grease products and grooves 15. The gate 7 (10) is made in the form of several patch strips 16 installed respectively in the grooves 12 and 15 and overlapping the rectangular holes 11 and 14 with the formation of an overflow edge 9 of the gutter 3 of clarified water and overflow th edge 8 zhirosliva.

 The mark of the base of each hole 11 is set according to the permissible minimum level of purified water in the device, and the height of the maximum permissible level of purified water. The length of the hole is 10-15% of the diameter of the overflow wall 4, therefore, the height of the hole is 0.15 m and the length is 0.4 m. The height of the hole 14 is 0.15 m and the width is 0.3 m.

 The device operates as follows.

 The purified water enters the lower zone of the flotation chamber 2. Fatty substances are floated in the upper part of the chamber 2, and the water separated from them in the lower part of the chamber 2 enters the housing 1 of the device, rises into the annular groove 3, where it flows over the overflow edge 9 of the gate 10 and leaves through hole 5 of the gutter 3 into the circulating water supply. The fat mass that has surfaced on the surface of the flotation chamber 2 is dumped into the pocket 6, poured over the edge 8 of the gate 7 and goes into the grease chamber of the pump room (not shown).
