Description
Technical Field
[0001] This utility model relates to the field of lubricating oil processing technology, and specifically to an emulsion separation and recovery device in lubricating oil processing. Background Technology
[0002] In the lubricating oil processing, the separation and recovery of emulsions are key technical aspects. Emulsions are typically formed by a mixture of lubricating oil, water, and impurities, requiring efficient separation equipment to separate the oil and water, recover usable lubricating oil, and reduce waste discharge. Traditional separation methods often employ static stratification or simple filtration, but these suffer from low separation efficiency, significant oil-water interface disturbance, and incomplete impurity removal, affecting the purity of the recovered oil and resource utilization. Furthermore, existing equipment often lacks heating capabilities, resulting in poor flowability of high-viscosity emulsions and prolonged separation time; the difficulty in cleaning filtered impurities also increases maintenance costs. Summary of the Invention
[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use emulsion separation and recovery device for lubricating oil processing, which can effectively solve the defects and shortcomings of the existing technology.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a separation box, support feet, and a feed pipe; support feet are fixed at the four corners of the outer bottom wall of the separation box, and a feed pipe is provided on the upper side wall of the separation box; it also includes:
[0005] Heating rods, wherein there are several heating rods and they are equally spaced inside the lower side of the feed tube, and the two ends of the heating rods are respectively fixed to the two inner walls of the feed tube;
[0006] The filter mechanism is located on the upper side inside the separation box. Collection boxes are embedded on both sides of the separation box, and the openings on the upper side of the inner wall of the collection boxes are connected to the interior of the separation box.
[0007] A flow guide plate is disposed on the lower side of the filtration mechanism. The outer peripheral wall of the flow guide plate is fixedly connected to the inner peripheral wall of the separation box. Several flow grooves are equidistantly arranged on one side wall of the flow guide plate.
[0008] The oil outlet pipe is located on one side of the separator. The inlet of the oil outlet pipe is inserted into and fixed inside the side wall of the separator. The end of the oil outlet pipe located inside the side wall of the separator is set in the same plane as the inner wall of the separator.
[0009] The water outlet pipe is arranged in a horizontal "Z" shape. The vertical pipe on one side of the water outlet pipe is connected to the bottom wall of the separation box, and the vertical pipe on the other side of the water outlet pipe is located in front of the oil outlet frame pipe.
[0010] With the above technical solution, the material is poured into the separation box through the feed pipe and heated by the heating rod at the same time. The heated material enters the separation box and is then filtered by the filtration mechanism. After filtration, it flows downward to the guide plate. Guided by the guide plate, it flows down the inner wall of the separation box from the guide channel to the lower side of the separation box, avoiding the impact on the liquid level during the flow. The liquid in the lower side of the separation box undergoes oil-water separation during the static process. After a period of time, when the oil level reaches the upper side of the oil outlet pipe, the oil is discharged through the oil outlet pipe. When the water level is too high, the control valve on the water outlet pipe is opened to facilitate the discharge of water.
[0011] As a further improvement of this utility model, a connecting pipe bracket is fitted and fixed on the horizontal pipe of the water outlet pipe and the cylindrical pipe on the lower side of the oil outlet bracket pipe, and the other side of the connecting pipe bracket is fixed on the outer wall of the separation box.
[0012] The above technical solutions can increase the stability of the water outlet pipe and the oil outlet support pipe.
[0013] As a further improvement of this utility model, the water outlet pipe is located on the top wall of the vertical pipe below the separation box and a discharge hopper is fixed thereon. The discharge hopper is embedded and fixed inside the bottom wall of the separation box, and the upper side of the discharge hopper is set on the same plane as the inner bottom wall of the separation box.
[0014] The above technical solution facilitates the guidance of materials within the separation box, preventing materials from remaining inside.
[0015] As a further improvement of this utility model, a guide bucket is suspended on the upper side of the guide plate, and the outer peripheral wall of the guide bucket is fixedly connected to the inner peripheral wall of the separation box.
[0016] The above technical solution facilitates the guidance of filtered materials and prevents materials from dripping directly down the flow channel, thus affecting the settling of the liquid.
[0017] As a further improvement of this utility model, the filtration mechanism includes:
[0018] The filter layer is located on the upper side inside the separation box. The filter layer is composed of several "W" shapes connected end to end. The front and rear sides of the filter layer are fixed to the inner walls of the front and rear sides of the separation box, respectively. The left and right sides of the filter layer are set to cooperate with and abut against the collection box.
[0019] The cleaning plate has its lower side clamped onto the upper surface of the filter layer. Reciprocating screws are inserted into the front and rear side walls of the cleaning plate. The two ends of the reciprocating screws are respectively screwed into the left and right side walls of the separation box through bearings. The two reciprocating screws are connected by a synchronous wheel transmission assembly. The screw nuts on the reciprocating screws are fixedly connected to the inner wall of the cleaning plate.
[0020] The cleaning motor is embedded and fixed in one side wall of the separation box, and the output shaft of the cleaning motor is connected to one end of one of the reciprocating lead screws.
[0021] Through the above technical solution, the starting cleaning motor enters the separation box through the feed pipe, and the cleaning motor drives the reciprocating lead screw connected to it to rotate. The reciprocating lead screw drives another reciprocating lead screw to rotate through the synchronous wheel transmission assembly. The two reciprocating lead screws drive the cleaning plate to move through their respective screw nuts. The cleaning plate moves within the filter layer, thereby cleaning the filter layer. The cleaned impurities enter the collection boxes on both sides respectively.
[0022] As a further improvement of this utility model, a support rod is sleeved on the outer side of the reciprocating screw, and the two ends of the support rod are respectively fixed on the inner walls of the two sides of the separation box. The screw nut on the reciprocating screw passes through the sliding groove on the lower side wall of the support rod and is fixedly connected to the cleaning plate.
[0023] The above technical solution allows the cleaning plate to be supported by a support rod, while simultaneously shielding the reciprocating screw and reducing the impact of materials on it.
[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The emulsion separation and recovery device in lubricating oil processing described in this utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

A discharge hopper 11 is welded and fixed to the top wall of the vertical pipe on the lower side of the water outlet pipe 9. The discharge hopper 11 is embedded and welded and fixed in the bottom wall of the separation box 1. The upper side of the discharge hopper 11 is set at the same plane as the inner bottom wall of the separation box 1, which can facilitate the guidance of materials in the separation box 1 and prevent materials from being stuck in the separation box 1. A connecting pipe frame 10 is sleeved and welded and fixed on the horizontal pipe of the water outlet pipe 9 and the cylindrical pipe on the lower side of the oil outlet frame pipe 8.

[0039] See Figure 2 , Figure 5 As shown, based on Embodiment 1, the filtering mechanism 5 includes:
[0040] The filter layer 5-1 is located on the upper side inside the separation box 1. The filter layer 5-1 is composed of several "W" shapes connected end to end. The front and rear sides of the filter layer 5-1 are welded and fixed to the inner walls of the front and rear sides of the separation box 1, respectively.

Impurities are automatically collected in the side box, reducing manual maintenance and extending the life of the device.
[0047] 3. The guide plate 7 and the guide bucket 12 work together to make the material flow smoothly along the box wall, avoid impacting the liquid surface, and ensure a more thorough oil-water separation effect.
