Description

Technical Field

[0001] The present application relates to the field of centrifugal separation technology, and in particular to a marine disc separator with a pressure-stabilizing valve. Background Art

[0002] Disc separator is a machine that uses the separation force generated by high-speed rotation to separate, clarify, and concentrate immiscible materials such as suspensions and emulsions. It is mainly composed of a base, transmission parts, a drum, inlet and outlet pipes, a cover, a motor, and a sensor. The drum is the main component for separating, clarifying, and concentrating materials. During the working process, the drum rotates at high speed to generate a large separation force.

[0003] In order to make the disc separator work properly, the interface between the light phase and the heavy phase in the flow field inside the disc of the disc separator needs to be kept at the appropriate position. At this time, the light phase outlet and the heavy phase outlet of the disc separator need to be kept in an appropriate pressure combination to ensure that the heavy phase of the disc separator cannot leak from the light phase outlet, and the light phase cannot leak from the heavy phase outlet, ensuring the normal operation of the disc separator.

[0004] For disc separators used on land, the outlet pressure is relatively fixed, so the drum can be designed during the design phase to ensure that the interface remains in the proper position to ensure the separation effect. However, for marine disc separators, there are often a large number of pipelines connected to the outlet, so it is impossible to ensure that the outlet pressure of the disc separator remains at the proper pressure. Therefore, some methods are needed to ensure that the outlet of the marine disc separator is stabilized at the proper pressure. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the existing disc separator is not suitable for the marine environment with a large number of connecting pipelines; to solve the problem that the outlet back pressure of the existing disc separator needs to be manually adjusted; to reduce the human resources required for the disc separator, and effectively reduce the difficulty of using the disc separator.

[0006] The embodiment of the present invention provides a marine disc separator with a pressure stabilizing valve, comprising: a marine disc separator body, an inlet and outlet pipe system and a pressure stabilizing valve;

[0007] The inlet and outlet pipe system includes a feed inlet, a light phase outlet and a heavy phase outlet;

[0008] The pressure stabilizing valve is arranged on the pipeline of the light phase outlet.

[0009] In some embodiments, the pressure-stabilizing valve includes: a valve body, a valve cover, a spring pressure regulating button, a spring, a diaphragm and a piston.

[0010] In some embodiments, the valve cover cooperates with the valve body to provide a flow passage for the fluid and fix internal components.

[0011] In some embodiments, the spring pressure adjustment button is mounted on the valve cover.

[0012] In some embodiments, the spring is arranged corresponding to the spring pressure adjustment button.

[0013] In some embodiments, the diaphragm is fixed between the valve body and the valve cover to perform liquid sealing and adjust the position of the piston.

[0014] In some embodiments, the diaphragm material comprises oil resistant rubber.

[0015] In some embodiments, the piston is arranged corresponding to the spring and the diaphragm, and can move under the action of the elastic force of the spring and the pressure of the diaphragm.

[0016] In some embodiments, the pressure-stabilizing valve adjusts its opening through the combined action of fluid pressure and elastic force, thereby adjusting the pressure of the light phase outlet.

[0017] In some embodiments, the pressure regulating valve adjusts the opening through the combined action of fluid pressure and elastic force, thereby adjusting the pressure of the light phase outlet, including:

[0018] The piston is tightened by applying a pre-tightening force through the spring. When the light phase outlet pressure is greater than a preset upper limit threshold, the outlet fluid pressure causes the pressure in the cavity above the diaphragm to rise. Under the action of the elastic force of the spring and the fluid pressure, the piston moves downward, the opening of the pressure-stabilizing valve increases, and the downstream flow resistance decreases, thereby reducing the back pressure of the marine disc separator body.

[0019] On the contrary, when the light phase outlet pressure is less than the preset lower limit threshold, the outlet fluid pressure causes the pressure in the cavity above the diaphragm to drop. Under the action of the elastic force of the spring and the fluid pressure, the piston moves upward, the opening of the pressure-stabilizing valve decreases, and the downstream flow resistance increases, thereby increasing the back pressure of the marine disc separator body.

[0020] The beneficial effects of the above embodiments include:

[0021] Using a pressure-stabilizing valve at the light phase outlet helps ensure that the marine disc separator works stably and meets the separation requirements; using a pressure-stabilizing valve at the light phase outlet helps reduce human resources and improve the convenience of using the disc separator.

The attached drawings are for reference only and are not used to limit the embodiments of the present application.

For example, it can be an electrical connection or a connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0030] It should be noted that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects, and do not represent a specific order for the objects. It is understandable that the specific order or sequence of "first\second\third" can be interchanged where permitted. It should be understood that the objects distinguished by "first\second\third" can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0031] The embodiment of the present invention provides a marine disc separator with a pressure stabilizing valve, such as Figure 1 and Figure 2 As shown, the marine disc separator is divided into two parts: the marine disc separator body 1 and the inlet and outlet pipe system. The inlet and outlet pipe system includes the feed inlet 2, the light phase outlet 3, and the heavy phase outlet 4. The pressure regulating valve 5 is installed on the pipeline of the light phase outlet 3. The working state of the heavy phase outlet 4 is relatively stable, and there is no need to use a pressure regulating valve.

[0032] The marine disc separator of this embodiment comprises a marine disc separator and a pressure stabilizing valve, wherein the pressure stabilizing valve 5 is connected and installed on the pipeline of the light phase outlet 3. The structure of the pressure stabilizing valve 5 is as shown in the attached figure. Figure 3As shown, the valve body 6 and valve cover 7 of the pressure-stabilizing valve 5 are made of stainless steel, which provide a flow channel for the fluid and fix the internal components; the spring pressure regulating button 8 is installed on the valve cover 7; the spring 9 is placed on the spring pressure regulating button 8, and a material that does not pollute the oil is used; the diaphragm 10 is fixed between the valve body 6 and the valve cover 7, which plays the role of liquid sealing and adjusting the piston position, and the material selected is oil-resistant rubber; the piston 11 is installed under the spring and the diaphragm, and moves under the action of elastic force and diaphragm pressure.

[0033] The pressure-stabilizing valve 5 adjusts the opening by the combined action of fluid pressure and elastic force, and then adjusts the pressure of the light phase outlet 3 of the marine disc separator, specifically as follows: the piston 11 is tightened by applying a preload force through the spring 9. When the pressure at the light phase outlet 3 of the marine disc separator is relatively large, here, the relatively large pressure can be determined according to the preset upper pressure limit threshold, the outlet fluid pressure causes the pressure in the cavity above the diaphragm 10 to rise, under the action of the elastic force of the spring 9 and the fluid pressure, the piston 11 moves downward, the opening of the pressure-stabilizing valve 5 increases, the downstream flow resistance decreases, and the back pressure of the marine disc separator body is reduced; on the contrary, when the pressure at the light phase outlet 3 of the marine disc separator is relatively small, here, the relatively small pressure can be determined according to the preset lower pressure limit threshold, the outlet fluid pressure causes the pressure in the cavity above the diaphragm 10 to decrease, under the action of the elastic force of the spring 9 and the fluid pressure, the piston 11 moves upward, the opening of the pressure-stabilizing valve 5 decreases, the downstream flow resistance increases, and the back pressure of the marine disc separator body is increased. In this way, the pressure at the light phase outlet 3 of the marine disc separator can be kept stable. The stable pressure required for the light phase outlet 3 of the marine disc separator can be adjusted by selecting the stiffness of the spring and adjusting the spring pressure adjustment button 8. This stabilizes the position of the interface inside the disc separator and ensures the normal operation of the disc separator.

[0034] The technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
