Description

The present invention relates to a liquid recovery float apparatus connected to a liquid recovery apparatus that recovers floating oil and slam floating on the liquid surface.

As a means of recovering floating oil and slums floating in the washing and processing liquid tanks used in conventional food and industrial product manufacturing factories, use the float pipe with the suction port of the discharge pipe facing upward. There are known means for recovering floating oil and slam floating on the liquid surface by a liquid recovery device by connecting and maintaining a constant water immersion position from the liquid surface.

For example, “a cooperative structure between a recovery unit and a recovery pump in an oil recovery / separation apparatus” (Patent Document 1) has been proposed. However, since the proposal employs a structure in which the direction of the discharge pipe for collecting floating oil, slum, etc. floating on the liquid surface is upward, the following problems are pointed out.
(1) Since the upward suction port with respect to the diameter of the discharge pipe is small, it is impossible to continuously collect a large amount of floating oil, slum, etc. floating on the liquid surface.
(2) When the liquid level is undulating, liquids other than floating oil and slum flow into the inlet of the discharge pipe.
(3) Since the discharge pipe and the float body protrude from the main body to the side surface, the mounting position is limited, and a certain installation space is required, so it cannot be installed in a small liquid tank.
(4) Since the scraping and collecting blade rotates on the liquid level at the center of the suction port of the discharge pipe, the vortex flow from the center is generated and the floating oil and slam are dispersed and the floating oil and slum Recovery force is poor because the force that pushes near the suction port is partially offset. (If a certain amount of floating oil or slam is generated, there is no problem because the pushing force is better)
(5) Since the recovery pump of the liquid recovery device is always operating regardless of the degree of floating oil and slum generation, it consumes a lot of power.
(6) In the case of a gyro-type liquid recovery device, the discharge pipe is located below and around the surface of the main body of the device. The float balance of the device body is poor.

On the other hand, a “floating oil recovery tank” (Patent Document 1) that collects floating oil that has flowed out to the sea surface using a natural phenomenon has been proposed. However, in the proposal, the bellows portion is extended by the weight of the floating oil flowing in, and the weight and the buoyancy corresponding to the pushed-off seawater amount are almost equalized so that the position of the oil inflow inlet faces the floating oil layer. However, it is used in manufacturing plants, such as the management of the installation position of the tank body, the problem of visual management of the recovery state, the problem of manual operation of the recovery work, the problem of clogging with dust and slum near the oil inflow weir, etc. There was a problem in applying it to a liquid recovery device.

In view of the current state of the conventional liquid recovery device as described above, the present applicant arranges the sliding pipe portion, the inflow weir adjusting portion, the float portion, and the scraping rotation device on the vertical axis, The recovered liquid storage recess of the float part and the suction port of the drain pipe are separately provided below the inflow weir of the inflow weir adjustment part, thereby reducing the size of the liquid recovery device, reducing power consumption, and improving the recovery efficiency. Focusing on the fact that it can be improved, the present inventors have proposed the “liquid recovery float device” in the present invention.

The float sensor 22 is installed on the upper surface of the lid 21 and detects the recovered liquid level S of the floating oil F1 and slam F2 recovered in the recovered liquid storage recess 37 of the float 30. Sensors are used. Further, a balance weight B is disposed at the opposite position by the weight of the float sensor 22. If the liquid recovery device K and the recovery pump 2 are always operated, the float sensor 22 is not necessary.

A plurality of inflow weirs 25 are provided at equal intervals on the outer peripheral wall surface 24 extending below the periphery of the lid portion 21 so as to have the height of the amount of change in the liquid level L. This is a gate port for taking oil F1, slam F2, and the like into the recovery chamber 31 of the float unit 30. Further, the inflow weir 25 extends downward by an adjustment stroke distance (change amount of the liquid level) of the inflow weir adjustment mechanism 26, and the inflow weir adjustment mechanism 26 provided on the inside adjusts the float 30. When the upper end portion 36 is lowered, the inflow weir lower side 25a (the upper end portion 36 of the float portion 30) is lowered to follow the liquid level L in the liquid tank.

The float part 30 forms a cylindrical collection chamber 31 whose upper part is open, and the inner bottom part is formed with a bowl-shaped slope part 32 whose center part is tapered to a taper, and the bottom part is a hole below. A recovery liquid storage recess 37 that is recessed in a shape is formed, a float body 33 having a floating body structure is formed in the lower part, and an inflow weir adjustment that is connected to the inflow weir adjustment mechanism 26 of the lid body part 21 at the upper part of the outer peripheral edge.

Clogging of the inflow weir 25 is prevented by positively attracting the floating oil F1 and slam F2 that float to the collection chamber 31 of the float section 30, thereby improving the collection efficiency of the floating oil F1 and slam F2. The scraping and rotating device 50 is not necessary when used when the fluid has high fluidity, such as floating oil having high fluidity or the ocean, and when the waveform is high and the wave pressure is high.

The drive device 51 is driven by a gear wheel meshing with the drive motor 52 as a drive source, and is operated at a low speed of about 20 to 30 rpm. Further, the transmission means to the scraping rotation device 50 side employs a structure in which the relay gear wheel 55 is indirectly connected. Specifically, the transmission means is slidably pressed by a spring 56 on a shaft having a square diameter of the drive motor 52. The connecting piece 57 is loosely fitted to the shaft in a free state, and is connected via the chevron engaging groove 59 of the relay gear wheel 55 that is locked by the W nut 58 and the chevron engaging groove 59 of the connecting piece 57, Further, it is meshed with a scraping gear wheel 54 connected to the scraping rotation device 50, and it adopts a transmission means for preventing the drive motor 52 from being burned out by being caught by the inflow weir 25.
