Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation equipment, in particular to a spiral tube type oil-water separator. Background Art

[0002] Environmentally friendly treatment of kitchen waste will produce a lot of sewage. This sewage contains a large amount of food particles and grease. It is nutrient-rich and easily breeds bacteria. The foul odor produced seriously affects the air quality, and the impact of sewage on the soil environment is even worse.

[0003] At present, the equipment used by the kitchen waste treatment stations for oil-water separation of sewage generated by kitchen waste are all various general oil-water separators on the market. Traditional oil-water separators usually use air flotation to accelerate the separation of grease or use inclined tubes to use scraper mechanisms to collect grease. Although the air flotation oil-water separator can accelerate the floating of grease, it also brings more suspended matter. The suspended matter particles in kitchen waste sewage have particularly strong adhesion, which easily causes floating oil to adhere to a large number of kitchen waste particles, resulting in difficulty in separation. The surface of the inclined tube oil-water separator is adhered to a large number of kitchen waste particles, which are difficult to clean, causing the inclined tube oil-water separator to lose its function. In addition, these two water separators also have the following problems: kitchen waste particles adhere to the water level sensor, causing it to malfunction, and when the oil content of the sewage is high, the grease is not collected thoroughly, and when the oil content is low, the collected grease has a large water content, so that these traditional oil-water separators are only suitable for the treatment of sewage generated by kitchen and restaurant cleaning, but are unable to cope with large-scale industrial treatment of kitchen waste sewage.

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like used in the present invention to indicate the orientation or position relationship is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 As shown, a preferred embodiment of a spiral tube oil-water separator provided by the present invention comprises a liquid infusion pipe 1, a base frame 2, an oil infusion pipe 3, a water collecting tank 4 and a water pump 5, wherein the liquid infusion pipe 1 is arranged on the base frame 2, specifically, the liquid infusion pipe 1 is mounted on the base frame 2, the liquid infusion pipe 1 is a spiral tube, the axis of the liquid infusion pipe 1 is horizontally arranged, the liquid inlet end of the liquid infusion pipe 1 is connected to the water pump 5, the liquid outlet end of the liquid infusion pipe 1 is located at the lowest end of the liquid infusion pipe 1 and its axis is horizontally arranged, the upper part of the liquid outlet end of the liquid infusion pipe 1 is connected to the oil infusion pipe 3, the oil infusion pipe 3 is arranged on the base frame 2, the lower part of the liquid outlet end of the liquid infusion pipe 1 is connected to the water collecting tank 4, specifically, the water inlet of the water pump 5 is connected to a sewage source, and the bottom surface of the water collecting tank 4 is connected with a water outlet pipe 41.

[0027] When in use, sewage is sucked into the infusion tube 1 through the water pump 5, and the sewage flows in the infusion tube 1. Under the action of centrifugal force, the density of oil is less than that of water, so that the oil with relatively small density gradually gathers on the side of the infusion tube 1 close to the center line of the infusion tube, and the water with relatively large density is thrown to the side of the spiral tube away from the center line of the infusion tube. The oil flows out through the oil pipe 3 and the water is diverted to the water collecting tank 4, thereby realizing oil-water stratification. The invention is convenient to operate, small in size, and low in manufacturing cost. It can be used to treat a large amount of sewage, has high operating efficiency, and high sewage treatment performance. It is particularly suitable for use in large industrial production sites and most small civilian sites, and has few mechanical moving parts, simple structure, and convenient maintenance.

[0028] For example, Figure 1 As shown, in order to facilitate the installation of parts, a liquid inlet pipe is provided at the liquid inlet end of the infusion tube 1, and the liquid inlet end of the infusion tube 1 is located at the lowest end of the infusion tube 1. One end of the liquid inlet pipe is horizontally connected to the infusion tube 1, and the other end of the liquid inlet pipe is vertically connected to the water pump 5; specifically, the liquid inlet pipe is an L-shaped tube.

[0029] For example, Figure 1 and 2As shown, the liquid outlet end of the liquid infusion pipe 1 is connected to the box wall of the water collecting tank 4, and the oil pipe 3 is connected to the base frame 2 through an adjusting component 6. The adjusting component 6 can drive the oil pipe 3 to move up and down. The operator can adjust the position of the oil pipe 3 by driving the oil pipe 3 up and down through the adjusting component 6 according to the oil content of the sewage, so as to adjust the amount of oil entering the oil pipe 3 and the amount of water entering the water collecting tank 4, thereby changing the thickness of the intercepted oil layer, improving the effect of oil-water separation, and the collection effect of grease and moisture, and is suitable for treating sewage with different oil contents, with a wide range of applications and strong practicality.

[0030] For example, Figure 2 and 3 As shown, the adjustment component 6 includes a fixing frame 61, a screw rod 62, a hand wheel 63 and a limit plate 66. One side of the fixing frame 61 is connected to the base frame 2, and the limit plate 66 is fixedly arranged on the other side of the fixing frame 61. The hand wheel 63 is provided with the limit groove 631, and the limit plate 66 is provided with a limit hole 661 rotatably matched with the limit groove 631. The fixing frame 61 is provided with a through hole for the screw rod 62 to pass through. The upper part of the screw rod 62 is threadedly connected to the hand wheel 63, and the lower end of the screw rod 62 is fixedly connected to the oil pipeline 3. The oil inlet end face of the oil pipeline 3 is in close contact with the liquid outlet end face of the liquid delivery pipe 1. When in use, the operator rotates the hand wheel 63 to drive the screw rod 62 to move up and down, thereby driving the oil pipeline 3 to move up and down. It is easy to use, simple in structure and low in cost.

[0031] For example, Figures 3 to 5 As shown, the adjustment assembly also includes a pressure plate 64, one end of which is clamped with the limit groove 631, and the pressure plate 64 presses the hand wheel 63 onto the fixing frame 61 through the locking bolt 67. After adjusting the position of the oil pipeline 3, the locking bolt 67 is tightened to press the hand wheel 63 onto the fixing frame 61, thereby locking the hand wheel 63.

[0032] For example, Figures 2 to 5 As shown, the adjustment assembly 6 also includes a guide column 65, the lower end of which is fixed on the oil pipeline 3, and the upper part of the guide column 65 is slidably connected to the fixing frame 61. Specifically, two guide columns 65 are provided and symmetrically arranged on the left and right sides of the screw rod 62. The setting of the guide column 65 plays a guiding role, and at the same time, further prevents the oil pipeline 3 from rotating when moving, thereby ensuring the smoothness of the oil pipeline 3 when moving.

[0033] For example, Figure 5As shown, the guide column 65 is provided with a scale line 651; thus, the operator can pre-set the scale values ​​corresponding to different oil contents of treated sewage according to experiments, which is convenient for the operator to adjust the oil pipeline 3 up and down according to the oil content of the sewage until the guide column 65 moves to the effective scale, thereby improving the effect of oil-water separation, and there is no need to judge the position of the oil pipeline 3 based on work experience, which is particularly suitable for novices and easy to use.

[0034] For example, Figures 3 to 5 As shown, the fixing frame 61 includes a horizontal plate 611 and a vertical plate 612 which are vertically arranged. The lower end of the vertical plate 612 is connected to the base frame 2 via a connecting bolt, and the upper end of the vertical plate 612 is connected to one end of the horizontal plate 611 via a connecting bolt. The screw rod 62 and the guide column 65 are both arranged at the other end of the horizontal plate 611 to facilitate the loading and unloading of the horizontal plate 611 and the vertical plate 612.

[0035] For example, Figure 5 and 6 As shown, the oil delivery pipe 3 includes a first oil pipe 31 and a second oil pipe 32, one end of the first oil pipe 31 is connected to the liquid outlet end of the delivery pipe 1, the bottom of the other end of the first oil pipe 31 is connected to the top of one end of the second oil pipe 32, the other end of the second oil pipe 32 is open downward, and an oil collecting tank is provided below the other end of the second oil pipe 32, so that the grease in the first oil pipe 31 can flow smoothly to the oil collecting tank through the second oil pipe 32; specifically, in the present embodiment, the first oil pipe 31 and the second oil pipe 32 are vertically arranged, and the operator can place the oil collecting tank in different positions according to the working area, so as to realize the rationalization of the spatial layout and reduce the occupied space.

[0036] In the description of the present invention, it should be understood that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" used in the present invention should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
