Detailed Description

The existing small oil-water separation equipment used in the catering industry is generally composed of a shell 1 used for storing oil water to be separated, a water inlet 1a and a water outlet 1b are arranged on the shell 1, in addition, a filter plate 2 which is used for filtering oil stains and is provided with filter holes 2a is transversely arranged in the shell 1, when the small oil-water separation equipment is used, untreated oil water flows into the shell 1 from the water inlet 1a, the water inlet 1a is usually arranged on the upper part of the shell 1 and above the filter plate 2 for the convenience of flowing in, so that the oil water can flow through the filter plate 2 by means of self gravity to play a role of filtering the oil stains, and the water passing through the filter plate 2 is directly discharged from the shell 1 through the water outlet 1b, and the oil absorption is insufficient due to the short contact time of the filter plate and the filter plate 2.

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

As shown in fig. 1 and 2, the present pressure type oil-water separation apparatus is different from the above-mentioned conventional oil-water separation apparatus in that a water pressurizing assembly for pressurizing oil-water below the filter plate 2 toward the filter plate 2 is provided below the filter plate 2 in the casing 1.

As an alternative structure of the water pressurizing assembly, the water pressurizing assembly consists of a driver 5a, a telescopic shaft 5b and a pressure plate 5c, and when the water pressurizing assembly is used, the driver 5a pushes the pressure plate 5c for pressurizing water to move back and forth through the telescopic shaft 5 b.

It should be noted that the driver 5a has a function of pushing the pressing plate 5c to perform a linear reciprocating motion, and an air cylinder may be generally selected, but of course, another driver capable of implementing the function or a matching of the driver and the corresponding linkage member may be used as required.

It should be noted that the position of the water inlet 1a is not necessarily provided at the upper portion of the casing 1, i.e., above the filter sheet 2, but may be provided below the filter sheet 2, and it is needless to say that the water inlet 1a may be preferably provided above the filter sheet 2, which increases the chance of primary oil-water separation.

In order to push as much floating oil as possible from the oil water into the filter sheet 2 when the water is pressurized, the size and shape of the surface of the pressure plate 5c adjacent to the filter sheet 2 on one side is substantially the same as those of the surface of the filter sheet 2 corresponding to the side surface, so that each of the filter holes 2a of the filter sheet 2 can be fully utilized.

In some embodiments, in order to keep the path of the pressure plate 5c moving back and forth substantially the same all the time, a position limiting component is disposed between the pressure plate 5c and a pair of inner side walls correspondingly disposed along the inside of the housing 1 in the moving direction of the pressure plate 5 c.

As an optional limiting component, it includes a pair of limiting grooves on a pair of inner side walls correspondingly arranged and opened in the housing 1, and a pair of limiting blocks convexly arranged on the outer edge of the pressure plate 5 c.

As another alternative limiting component, as shown in fig. 1, it includes a pair of limiting blocks 8a protruding from a pair of inner side walls disposed correspondingly in the housing 1, and a pair of limiting grooves formed on the outer edge of the pressing plate 5 c.

In some embodiments, in order to reduce the backflow of the oil content pushed to the opposite upper surface of the filter plate 2 by the pressure plate 5c into the oil below the filter plate, as shown in fig. 3 and 4, the filter holes 2a in the filter plate 2 are configured to be smaller on the upper side and larger on the lower side, and in addition, as shown in fig. 4, in order to reduce the resistance of the oil content after entering the filter holes 2a, the filter holes 2a are arranged in a parabolic shape along the oil content moving direction.

In some embodiments, in order to reduce the frequency of removing the oil stains on the filter plate 2, the oil storage chamber 3 is arranged on one side in the housing 1, and one side of the filter plate 2 is connected with the opening at the top of the oil storage chamber 3, so that the oil stains attached to the filter plate 2 flow into the oil storage chamber 3 under the pushing of the water pressurizing assembly, and the oil stain removing frequency is reduced because the oil storage chamber 3 has a large space and can store more oil stains.

In addition, in order to clean the oil stain conveniently, an oil storage cylinder 3a for storing the oil stain can be placed in the oil storage chamber 3, so that the oil storage cylinder 3a filled with the oil stain is only required to be taken out during cleaning each time, and then the oil storage cylinder 3a is placed into an empty oil storage cylinder.

In some embodiments, in order to make the oil content in the filter plate 2 flow into the oil storage chamber 3 better, the filter plate 2 is positioned so as to be inclined upward from the side of the filter plate 2 connected to the oil storage chamber 3 to the side corresponding thereto, so that the oil content adhered to the filter plate 2 flows toward the oil storage chamber 3 by the gravity of itself, and at the same time, the filter plate 2 is made to make room for adsorbing more new oil content.

In some embodiments, it is considered that the oil in the filter plate 2 contains a lot of water (because most of the oil and water pressed in through the pressure plate 2 flows back into the oil below the filter plate 2 through the filter plate 2, but there is a lot of water flowing out on the upper surface of the filter plate 2), and therefore, a water outlet plate 4 is provided between the oil storage chamber 3 and the filter plate 2, and water outlet holes through which water flows out and oil cannot flow out are provided on the water outlet plate 4, so that the water flowing into the oil storage chamber 3 can be reduced, and the frequency of cleaning the oil storage chamber 3 can be reduced.

In some embodiments, in order to make the oil in the oil water float up to the upper part of the oil water as soon as possible, an aeration head 6 is arranged in the housing 1 below the filter plate 2, a large amount of micro bubbles are generated through the aeration head 6, and the micro bubbles can rise continuously to reach the upper part of the oil water, so that the oil in the oil water moves upwards along with the bubbles by attaching to the aeration head, the oil floating speed is accelerated, more oil is accumulated on the upper surface of the oil water in a short time, and the pressing plate 5c can press more oil to the pressing plate 5c at a time to improve the efficiency.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms of the housing 1, the water inlet 1a, the water outlet 1b, the filter plate 2, the filter hole 2a, the oil storage chamber 3, the oil storage cylinder 3a, the water outlet plate 4, the driver 5a, the telescopic shaft 5b, the pressure plate 5c, the aeration head 6, etc. are used more herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
