Description

Technical Field

[0001] The utility model relates to the technical field of pre-degreasing equipment for a pretreatment line, in particular to an oil skimming device applied to pre-degreasing and degreasing tanks of a pretreatment line. Background Art

[0002] The pre-degreasing and degreasing tanks of a pretreatment line are equipment for treating the grease on the vehicle body, and their function is to remove the grease on the vehicle body using the bath liquid added with a degreasing agent. As the number of uses increases, the grease on the liquid surface in the tank will gradually increase, affecting the degreasing effect after the vehicle body exits the tank. In order to improve the utilization rate of the bath liquid in the degreasing tank, an oil-water separator needs to be additionally provided to treat the grease in the bath liquid.

[0003] The existing oil-water separators in the prior art have a relatively complex structure and a relatively high cost. Summary of the Utility Model

[0004] How to realize the automatic treatment of the bath liquid in the degreasing tank to improve its utilization rate is a difficult point to be solved. At the same time, optimizing the installation method to make it adapt to liquid surfaces at different heights also needs to be considered together. Therefore, in view of these problems, the utility model designs an oil skimming device for pre-degreasing and degreasing tanks of a pretreatment line, which has an adjustable installation height, is convenient and reliable to install, has strong versatility, and can automatically treat the grease in the bath liquid of the degreasing tank.

[0005] The utility model is realized by the following technical solutions: An oil skimming device applied to pre-degreasing and degreasing tanks of a pretreatment line includes a rotating shaft assembly, a body, two tank fixing brackets, and a limiting device. The rotating shaft assembly includes a bracket connecting shaft and a rotating shaft, and the rotating shaft and the bracket connecting shaft are vertically arranged and fixedly connected to each other.

[0006] In order to realize the automatic oil skimming function of the device, the body is a semi-closed thin-walled structure, with a liquid inlet opened at the upper part, and is communicated with a waste liquid collection device through a hose at the bottom. One side of the body is sleeved on the rotating shaft through a bushing assembly, and the other side is connected to the end of the rotating shaft through a spacer sleeve assembly, and the body can swing freely around the rotating shaft.

[0007] Specifically, the bushing assembly includes a bushing, a pressing plate, and a bushing bolt and nut assembly. The bushing is sleeved on the rotating shaft, and the bushing bolt and nut assembly tightly connects the body and the pressing plate to both sides of the bushing respectively. The spacer sleeve assembly includes two spacer sleeves, a spacer sleeve bolt, and a spacer sleeve nut. The two spacer sleeves are coaxially sleeved on the spacer sleeve bolt and are screwed on the end of the rotating shaft through the spacer sleeve nut. The other side of the body is sleeved on the spacer sleeve bolt and is arranged between the two spacer sleeves.

[0008] In order to limit the rotation angle of the body around the rotating shaft, the limiting device includes a limiter and a limiting block. The limiter has a connecting portion, a connecting hole is formed in the connecting portion, two limiting portions extend outward from the connecting portion, a limiting groove is formed between the two limiting portions, the limiter is fixedly sleeved on the rotating shaft through the connecting hole, and the limiting block is fixedly connected to the bushing assembly corresponding to the limiting groove and can swing in the limiting groove along with the bushing assembly.

[0009] The tank body fixing bracket is used to install the entire oil skimming device at the corresponding position of the degreasing tank. In order to adapt to liquid levels at different heights and improve the versatility of the device, the tank body fixing bracket is height-adjustably connected to the bracket connecting shaft, thereby realizing the adjustment of the installation height of the body.

[0010] Preferably, the tank body fixing bracket is height-adjustably connected to the bracket connecting shaft through a U-shaped bolt assembly.

[0017] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0018] As Figure 1-2 shown, an oil skimming device applied to the pre-degreasing and degreasing tanks of a pre-treatment line includes a rotating shaft assembly 1, a body 2, two tank fixing brackets 3, and a limiting device 4. The rotating shaft assembly 1 includes a bracket connecting shaft 11 and a rotating shaft 12. The rotating shaft 12 and the bracket connecting shaft 11 are vertically arranged and fixedly connected to each other. The body 2 is a semi-closed thin-walled structure, with a liquid inlet 21 opened at the upper part, and the bottom is communicated with a waste liquid collection device through a hose 8. One side of the body 2 is sleeved on the rotating shaft 12 through a bushing assembly 5, and the other side is connected to the end of the rotating shaft 12 through a spacer sleeve assembly 6.

[0019] As Figure 3 shown, the bushing assembly 5 includes a bushing 51, a pressure plate 52, and a bushing bolt and nut assembly 53. The bushing 51 is sleeved on the rotating shaft 12, and the bushing bolt and nut assembly 53 presses and connects the body 2 and the pressure plate 52 on both sides of the bushing 51 respectively. As Figure 4 shown, the spacer sleeve assembly 6 includes two spacer sleeves 61, a spacer sleeve bolt 62, and a spacer sleeve nut 63. The two spacer sleeves 61 are coaxially sleeved on the spacer sleeve bolt 62 and are screwed on the end of the rotating shaft 12 through the spacer sleeve nut 63. The other side of the body 2 is sleeved on the spacer sleeve bolt 62 and is arranged between the two spacer sleeves 61. The body 2 can swing freely around the rotating shaft 12.

[0020] The limiting device 4 includes a limiter 41 and a limiting block 42. As Figure 5As shown, the stopper 41 has a connecting portion 411, on which a connecting hole 4111 is formed. The connecting portion 411 extends outwardly with two limiting portions 412, and a limiting groove 413 is formed between the two limiting portions 412. The stopper 41 is fixedly sleeved on the rotating shaft 12 through the connecting hole 4111. The limiting block 42 is fixedly connected to the bushing assembly 5 corresponding to the limiting groove 413 and can swing in the limiting groove 413 along with the bushing assembly 5.

[0021] The tank body fixing bracket 3 is height-adjustably connected to the bracket connecting shaft 11 through a U-bolt assembly 7.

[0022] The working principle of the skimming device applied to the pre-degreasing and degreasing tanks of the pre-treatment line is as follows:

[0023] First, according to the height of the liquid level in the degreasing tank and the installation position, the height of the tank body fixing bracket 3 on the bracket connecting shaft 11 is adjusted through the U-bolt assembly 7 and then locked. Then, the entire skimming device is installed at the corresponding position in the degreasing tank by adjusting the tank body fixing bracket 3. At this time, the liquid inlet 21 of the main body 2 is at the liquid level position, and the skimming device for the pre-degreasing and degreasing tanks of the pre-treatment line starts the skimming operation. Specifically, the tank liquid with grease enters the main body 2 from the liquid inlet 21, driving the main body 2 to swing around the rotating shaft 12. The tank liquid then flows to the bottom and is discharged into the waste liquid collection device through the hose 8 for centralized treatment. According to its own weight, the main body 2 swings back to the initial position for the next skimming. During the swinging process of the main body 2, the stopper 41 is used in cooperation with the limiting block 42 that swings together with the main body 2, which can limit the swinging angle of the main body 2 around the rotating shaft 12.
