Description

Technical Field

[0001] This utility model relates to the field of AKD production technology, specifically to an oil separation device used in the AKD production process. Background Technology

[0002] The production process of AKD (alkyl ketene dimer) sizing and water-resistant agent often involves the treatment of oily wastewater. This wastewater contains a certain amount of grease and other suspended solids. If it is not effectively separated, it will not only burden subsequent wastewater treatment processes, but may also affect product quality and environmental safety.

[0003] Traditional oil-water separation devices, such as gravity separators, are ineffective at removing emulsified oil and fine particulate matter, resulting in substandard effluent quality. Furthermore, the oil-water filter elements of existing devices are inconvenient to replace, affecting subsequent treatment effects. Therefore, a high-efficiency oil-water separation device with pretreatment capabilities is needed in the AKD production process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide an oil separation device with pretreatment function in the AKD production process.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an oil separation device for AKD production process, including a processing box, a partition, a quick-release mechanism, a filter element and a pretreatment mechanism;

[0006] After the treatment box is placed stably by the support frame, there is a partition placed horizontally inside. The filter element is fixed to the top surface of the partition by a quick release mechanism, and multiple filter elements are arranged in sequence. Each filter element extends into the clean water chamber below the partition. The side wall of the treatment box is connected to a wastewater valve to discharge the impurities isolated by the filter element.

[0007] The treatment tank is equipped with a pretreatment mechanism. After the wastewater passes through the pretreatment mechanism to break up the emulsion, it enters the treatment tank. After being treated by the filter element to separate oil, the purified water automatically enters the purified water chamber.

[0008] As an improvement, the pretreatment mechanism includes a pretreatment chamber and heating coils;

[0009] The pretreatment box is fixed on the top surface of the treatment box. One side is connected to the feed pipe, and the other side is connected to the guide pipe extending into the treatment box. Multiple heating coils are embedded in the bottom inner wall. Under the action of the temperature controller on the outer wall of the pretreatment box, the heating coils heat the wastewater to the required temperature to achieve demulsification and improve the treatment quality.

[0010] As an improvement, a pressure pump is installed on the top surface of the treatment tank to pump the pretreated and demulsified wastewater from the pretreatment tank into the treatment tank, facilitating oil separation treatment by the filter element, which is an ultrafiltration membrane filter element.

[0011] As an improvement, the pretreatment mechanism also includes a stirrer; the stirrers are rotatably arranged inside the pretreatment tank, and multiple stirrers are arranged in sequence, each of which is driven to rotate by a motor on the top surface of the pretreatment tank.

[0012] As an improvement, the quick-release mechanism includes a service cover, a mounting through hole, and a sealing ring;

[0013] The bottom wall of the treatment chamber is hinged to a maintenance cover. After the maintenance cover is opened, each filter element passes through the mounting holes on the partition until it is tightly attached to the inner wall of the top of the treatment chamber. The inner wall of the top of the treatment chamber is fixed with a sealing ring that is tightly attached to the outer wall of each filter element, and the bottom of the filter element is limited and fixed by a positioning component, so as to realize the quick installation of the filter element and facilitate maintenance and replacement.

[0014] As an improvement, the positioning component is a cylindrical structure with an open top. After the positioning component is placed around the bottom of the filter element, it is threaded to the threaded groove on the inner wall of the mounting hole to support the bottom of the filter element, which can quickly and stably support the bottom of the filter element.

[0015] As an improvement, a cleaning nozzle is also included. A cleaning nozzle connected to an external water source is installed on the inner wall of the top of the treatment box. After the cleaning nozzle is installed inside the sealing ring, it extends into the filter element for rinsing, which facilitates backwashing of the filter element and removes impurities from the outer surface of the filter element.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. A pretreatment mechanism can be set up to break down the emulsion structure through heating, making it easier for the oil to be retained by the membrane and improving the treatment quality;

[0018] 2. The quick-release mechanism of the filter element facilitates its replacement, ensuring subsequent processing efficiency while improving subsequent processing results;

[0019] 3. The combination of multiple filter elements can greatly improve processing efficiency and quality. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] An oil separator for use in the AKD production process, combined with an attached Figure 1-5 As shown, it includes a treatment box 1, a partition 2, a quick-release mechanism, and a filter element 3. After the treatment box 1 is placed stably by the support frame 4, the partition 2 is placed horizontally inside. The filter element 3 is fixed to the top surface of the partition 2 by the quick-release mechanism, and multiple filter elements are arranged in sequence. The bottom of each filter element 3 extends into the clean water chamber 5 below the partition 2. The side wall of the treatment box 1 is connected to a wastewater valve 6, which is used to discharge the impurities isolated by the filter element 3.

[0029] The quick-release mechanism includes a maintenance cover plate 13, a mounting through hole 14, and a sealing ring 15. The maintenance cover plate 13 is hinged to the bottom wall of the processing box 1. After the maintenance cover plate 13 is opened, each filter element 3 passes through the mounting through hole 14 on the partition plate 2 until it is close to the inner wall of the top of the processing box 1. The inner wall of the top of the processing box 1 is fixed with a sealing ring 15 that is close to the outer wall of each filter element 3. The bottom of the filter element 3 is limited and fixed by the positioning component 16. The positioning component 16 is a cylindrical structure with an open top. After the positioning component 16 is placed around the bottom of the filter element 3, it is threaded to the threaded groove of the inner wall of the mounting through hole 14 to support the bottom of the filter element 3. The bottom of the filter element 3 can be quickly and stably supported.

[0030] The pretreatment mechanism is installed on the treatment tank 1. After the wastewater passes through the pretreatment mechanism to break the emulsion, it enters the treatment tank 1. After being treated by the filter element 3 to separate the oil, the purified water automatically enters the purified water chamber 5. The pretreatment mechanism includes a pretreatment box 7 and heating coils 8. The pretreatment box 7 is fixed on the top surface of the treatment tank 1. One side is connected to the feed pipe 9, and the other side is connected to the guide pipe 10 extending into the treatment tank 1. Multiple heating coils 8 are embedded in the inner wall of the bottom end. Under the action of the temperature controller on the outer wall of the pretreatment box 7, the heating coils 8 heat the wastewater to the required temperature to achieve demulsification and improve the treatment quality.

[0031] The pretreatment mechanism also includes a stirrer 11; the stirrer 11 is rotatably disposed inside the pretreatment tank 7, and multiple stirrers 11 are arranged in sequence, and each stirrer 11 is driven to rotate by a motor 12 on the top surface of the pretreatment tank 7.

[0032] It also includes a cleaning nozzle 17. The cleaning nozzle 17, which is connected to an external water source, is provided on the inner wall of the top of the treatment box 1. After the cleaning nozzle 17 is set inside the sealing ring 15, it extends into the filter element 3 for rinsing, which facilitates backwashing of the filter element 3 and removes impurities from the outer surface of the filter element 3.

[0033] In a specific implementation of this invention, wastewater first enters the pretreatment tank 7 through the feed pipe 9. The heating coil 8 is turned on by the temperature controller to heat the wastewater and break the emulsion structure. During the pretreatment process, the motor 12 is turned on to drive the stirrer 11 to rotate, thereby improving the demulsification efficiency. After demulsification, the wastewater is pumped into the treatment tank 1 by the pressure pump. Then, multiple filter elements 3 in the treatment tank 1 work. Impurities such as grease in the wastewater remain on the outer surface of the filter element 3. The purified water passes through the wall of the filter element 3 and enters the interior. Finally, it is discharged into the purified water chamber 5 through the bottom of the filter element 3. It can be taken out for use through the water valve of the purified water chamber 5.

[0034] After using it for a period of time, open the wastewater valve 6 to release and remove the grease and other impurities that have been separated on the outer surface of the filter element 3. Connect the cleaning nozzle 17 to the external water source so that clean water can be injected into the filter element 3 to backwash the filter element 3 and wash off the impurities on the outer surface.

[0035] When necessary, the filter element 3 can be replaced. By opening the maintenance cover 13, the positioning part 16 can be rotated out from the installation through hole 14 and the filter element 3 can be pulled down. After replacing the new filter element 3, the positioning part 16 can be screwed back into the installation through hole 14 to complete the replacement operation, ensuring oil separation efficiency and quality.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
