Description

[0001] Technical field

[0002] The utility model relates to the field of emulsion pumping station technology, in particular to a single-block emulsion pumping station.

[0003] Technology Level

[0004] Existing emulsion pumping stations typically include emulsion pumps, a reverse emulsion filter, an automatic dosing unit, and a liquid supply station. Various equipment is located close together, and existing emulsion pumping station equipment is large. Pipelines are used to connect the equipment, and for ease of installation, the spacing between devices is typically 1.5 meters. Multiple devices extend over ten meters in length, requiring significant space. When working in mines or other space-constrained environments, accommodating large and numerous pieces of equipment becomes impossible.

[0005] The essence of the utility model

[0006] The purpose of the utility model: in order to overcome the shortcomings of the existing level of technology, a monoblock emulsion pumping station is proposed, which solves the problem of the large occupied space of emulsion pumping stations.

[0007] The technical solution of the present utility model: a monoblock emulsion pumping station includes a frame (1) and emulsion pumps (2) connected to a mining face. An emulsion chamber (11) and an oil chamber (12) are located inside the frame (1). A detection unit for determining the emulsion concentration in the emulsion chamber (11) is installed on the frame (1). A dosing mechanism (3) and an incoming water filter (4) are located on the upper part of the frame (1). Water is fed through the incoming water filter (4) to the dosing mechanism (3) for preparing the emulsion and then fed to the emulsion chamber (11). A suction filter (5) is installed between the emulsion chamber (11) and the emulsion pump (2). A reverse emulsion filter (6) is installed between the emulsion chamber (11) and the mining face.

[0008] This technical solution eliminates the need for a reverse emulsion filter, automatic dosing unit, and liquid supply station. Instead, an emulsion chamber (11) and an oil chamber (12) are located directly within the frame. The automatic dosing unit is divided into a dosing mechanism (3) and a detection unit for determining the emulsion concentration, both mounted on the frame (1), saving space. The installation of a compact inlet water filter (4), suction filter (5), and reverse emulsion filter (6) replaces the reverse emulsion filter. This ensures the filtration of impurities such as metal particles during the emulsion preparation, feeding, and return stages, saving space occupied by the reverse emulsion filter and automatic dosing unit.

[0009] Additional installations of the present utility model: the dosing mechanism (3) includes an inlet electromagnetic valve (31) communicating with the inlet water filter (4), a dosing pump (32) communicating with the oil chamber (12), and an emulsifier (33) communicating with both the inlet electromagnetic valve (31) and the dosing pump (32). The emulsifier (33) communicates with the emulsion chamber (11).

[0010] In a preferred embodiment, an additional configuration is used: water and oil are separately fed into the emulsifier (33) for mixing. After reaching the required concentration, the mixture is fed into the emulsion chamber (11) for storage. The inlet solenoid valve (31), the metering pump (32), and the emulsifier (33) can be compact devices that occupy little space and are placed on the upper part of the frame (1). Feeding the emulsion to the upper part of the emulsion chamber (11) makes it possible to use gravity to accelerate the movement of the medium inside the chamber and improve mixing with the emulsion therein.

[0011] Additional installations of the present utility model: the detection unit for determining the emulsion concentration includes a concentration sensor (8) and a circulation pump (7) designed to feed the emulsion from the emulsion chamber (11) through the concentration sensor (8) and return it after measurement back to the emulsion chamber (11). The circulation pump (7) is mounted on the frame (1). Its inlet and outlet openings communicate with opposite sides of the emulsion chamber (11) to ensure circulation of the medium inside the chamber.

[0012] Additional installations of this utility model: the circulation pump (7) pumps out the emulsion from the bottom of one side of the emulsion chamber (11) and feeds it through the concentration sensor (8). This allows the dosing mechanism to adjust the concentration of the emulsion being prepared based on measurements, striving to achieve the required concentration in the emulsion chamber (11). Then, the circulation pump (7) feeds the measured emulsion back from the opposite side of the emulsion chamber (11), ensuring circulation of the emulsion inside the emulsion chamber (11) and intensifying the mixing of the emulsion composition.

[0013] In a preferred embodiment, an additional configuration is adopted: the emulsion chamber (11) includes an emulsion storage room (111), an upper inverse emulsion room (112), and a lower inverse emulsion room (113). The liquid storage room (111) communicates with the upper inverse emulsion room (112). The upper inverse emulsion room (112) and the lower inverse emulsion room (113) communicate with each other through an inverse emulsion filter (6). The emulsion returning from the production face enters the lower inverse emulsion room (113), after which it enters the emulsion storage room (111) through the inverse emulsion filter (6).

[0014] Additional installations of this utility model: the returning emulsion is fed into the lower inverse emulsion chamber (113). Heavy impurities (metallic or rubber) settle to the bottom, providing preliminary filtration. The remaining emulsion rises and passes through the inverse emulsion filter (6) for further purification, entering the upper inverse emulsion chamber (112), and then into the emulsion storage room (111) for subsequent use.

[0015] In a preferred embodiment, an additional configuration is used: a control unit (13) is additionally installed on the frame (1) for controlling the operation of the emulsion pump (2), the metering mechanism (3) and the detection unit for determining the concentration of the emulsion.

[0016] Additional features of this utility model: the control unit (13) integrates control of the emulsion pump (2), the dosing mechanism (3), and the emulsion concentration detection unit. This allows for control of all equipment from a single location, eliminating the need for personnel to move between devices, saving time and effort.

[0017] In a preferred embodiment, an additional configuration is adopted: a first oil level sensor 1 (9) and an emulsion level sensor (10) are respectively installed on the upper portion of the oil chamber (12) and the emulsion chamber (11). The readings of the oil level sensor 1 (9) and the emulsion level sensor (10) are displayed on the control unit (13).

[0018] In a preferred embodiment, an additional configuration is adopted: the liquid level in the oil chamber and the emulsion chamber is monitored, which allows personnel to monitor the volumes of oil and emulsion, and determine the need to start work or pump out oil.

[0019] In a preferred embodiment, an additional configuration is used: an oil temperature sensor (16) and a second oil level sensor (17) are installed on the emulsion pump (2). The readings of the oil temperature sensor (16) and the oil level sensor 2 (17) are displayed on the control unit (13).

[0020] Additional features of this utility model include monitoring the temperature and oil level in the emulsion pump (2). The results are displayed on the control unit (13), allowing personnel to assess the condition of the emulsion in the pump, determine its operating status, and plan further actions.

[0021] In a preferred embodiment, an additional configuration is used: the emulsion pump (2) is connected to the working face via a pressure accumulator (14) mounted on the frame (1). A system pressure sensor (15) is installed at the outlet of the pressure accumulator (14).

[0022] Additional features of this utility model: a pressure accumulator (14) compensates for leaks in the high-pressure hydraulic system, reducing the frequency of actuation of the electrohydraulic unloader valve in the emulsion pump (2), thereby extending its service life. It also absorbs hydraulic pulses in the system, eliminating vibrations in the pipelines caused by these pulses. A system pressure sensor (15) at the accumulator outlet monitors the pressure at the emulsion pump (2) outlet in real time, allowing for an assessment of its operating condition.

In the description of this utility model, the term "several" means at least two, for example, two, three, etc., unless explicitly stated otherwise.

[0033] Furthermore, the technical solutions of various embodiments of this utility model may be combined, but only on the basis of their feasibility by specialists in the given technical field. If a combination of technical solutions proves contradictory or impracticable, such a combination of technical solutions shall be deemed nonexistent and not covered by the scope of protection required by the utility model.

[0034] As shown in Fig. 1-3, the single-block emulsion pump station includes a frame (1) and an emulsion pump (2) connected to the working face. The frame (1) includes an emulsion chamber (11) and an oil chamber (12) located adjacent to each other. The oil chamber (12) is designed to store emulsified oil or highly concentrated emulsion, which is mixed with water to obtain an emulsion of a required concentration. The emulsion pump (2) is installed on the frame (1) and is located next to the emulsion chamber (11) and the oil chamber (12). A detection unit for detecting the concentration of the emulsion in the emulsion chamber (11) is installed on the frame (1). A metering mechanism (3) and an incoming water filter (4) are located on the upper part of the frame (1).

[0035] The metering mechanism (3) includes an inlet solenoid valve (31) communicating with the inlet water filter (4), a metering pump (32) communicating with the oil chamber (12), and an emulsifier (33) communicating with both the inlet solenoid valve (31) and the metering pump (32). Water is supplied through the inlet water filter (4) to the metering mechanism (3) to prepare an emulsion and then fed into the emulsion chamber (11). The water is preferably purified water. The inlet solenoid valve (31) regulates the flow rate of the inlet water. The emulsifier (33) is in communication with the upper part of the emulsion chamber (11), which allows the emulsion to be supplied to the upper part of the chamber.

[0036] By separately adjusting the flow rate of water (using the inlet solenoid valve (31)) and oil (using the metering pump (32)) supplied to the emulsifier (33), they are mixed in a required proportion. After reaching a certain concentration, the mixture is fed to the emulsion chamber (11) for mixing and storage. The metering pump (32) can not only feed oil to the emulsifier (33), but also pump oil from the external oil tank into the oil chamber of the oil (12). The inlet solenoid valve (31), the metering pump (32), and the emulsifier (33) can be compact equipment, occupying little space, and placed on the upper part of the frame (1). Feeding the emulsion to the upper part of the emulsion chamber (11) makes use of gravity to accelerate the movement of the medium inside the emulsion chamber (11) and improve mixing with the emulsion therein.

[0037] A suction filter (5) is installed between the emulsion chamber (11) and the emulsion pump (2). A reverse emulsion filter (6) is installed between the emulsion chamber (11) and the working face. The inlet filter (4) and suction filter (5) can be mesh filters. The inlet water filter (4) removes impurities from the water entering the metering mechanism. The suction filter (5) provides additional filtration of the emulsion entering the emulsion chamber (11) from the emulsion pump (2), effectively preventing metal impurities or other contaminants from entering the emulsion pump (2), which could lead to contamination or damage.

[0038] The emulsion chamber (11) includes an emulsion storage room (111), an upper inverse emulsion room (112), and a lower inverse emulsion room (113). The emulsion storage room (111) communicates with the upper inverse emulsion room (112). The upper inverse emulsion room (112) and the lower inverse emulsion room (113) communicate with each other through the inverse emulsion filter (6). The emulsion returning from the production face enters the lower inverse emulsion room (113), after which it enters the emulsion storage room (111) through the inverse emulsion filter (6). The inverse emulsion filter (6) can be of the filter element type, wherein the filter element is located inside the lower inverse emulsion room (113). The emulsion from the lower chamber of the reverse emulsion (113) passes through the layers of the filter element, is cleaned and enters the internal cavity of the cartridge.The purified emulsion then rises to the upper invert emulsion room (112) and then enters the emulsion storage room (111). The emulsifier (33) communicates with the emulsion storage room (111). The emulsion pump (2) is connected to the emulsion storage room (111) through the suction filter (5).

[0039] The emulsion concentration detection unit includes a concentration sensor (8) and a circulation pump (7) designed to feed the emulsion from the emulsion chamber (11) through the concentration sensor (8) and return it back to the emulsion chamber (11) after measurement. The circulation pump (7) is installed on the frame (1). The inlet and outlet ports of the circulation pump (7) communicate with the upper and lower parts of the emulsion chamber (11), respectively, which ensures circulation of the medium inside the emulsion chamber (11) when the pump is operating. The circulation pump (7) and the concentration sensor (8) can be fixed on the side wall of the oil chamber (12) and connected to the emulsion chamber (11) via pipelines.

[0040] The circulation pump (7) draws the emulsion from the bottom of one side of the emulsion chamber (11) and feeds it through the concentration sensor (8). This allows the dosing mechanism to adjust the concentration of the emulsion being prepared based on measurements, striving to achieve the desired concentration in the emulsion chamber (11). After measurement, the emulsion is returned by the circulation pump (7) to the top of the emulsion chamber (11) on the opposite side. The suction and pumping action of the circulation pump (7) creates a vertical movement of the emulsion in the chamber, promoting its mixing.

[0041] A control unit (13) is additionally mounted on the frame (1). The control unit (13) is mounted on the side wall of the oil chamber (12) next to the circulation pump (7), ensuring efficient use of space. The control unit (13) integrates control of the emulsion pump (2), metering mechanism (3), and emulsion concentration detection unit. This allows for control of all equipment from a single location, eliminating the need for personnel to move between devices, saving time and effort.

[0042] The first oil level sensor (9) and the emulsion level sensor (10) are installed in the oil chamber (12) and the emulsion chamber (11), respectively. This monitors the liquid level in the oil chamber and the emulsion chamber, allowing the personnel to monitor the volumes of oil and emulsion. An oil temperature sensor (16) and a second oil level sensor (17) are installed on the emulsion pump (2). This monitors the temperature and oil level in the emulsion pump (2), allowing the personnel to evaluate the state of the emulsion in the pump, determine its operating status, and plan further actions. The readings of the oil level sensor 1 (9), liquid level sensor (10), oil temperature sensor (16), and oil level sensor 2 (17) are displayed on the control unit (13), which facilitates the evaluation of the equipment status and allows the personnel to observe and perform corresponding operations from the control unit (13). The oil level sensors are liquid level sensors.

[0043] The emulsion pump (2) is connected to the working face via a pressure accumulator (14) mounted on the frame (1). A system pressure sensor (15) is installed at the outlet of the pressure accumulator (14).

[0044] The pressure accumulator (14) compensates for leaks in the high-pressure hydraulic system, reducing the frequency of actuation of the electro-hydraulic unloader valve in the emulsion pump (2), thereby extending its service life. It also absorbs hydraulic pulses in the system, eliminating vibrations caused by these pulses in the pipelines. The system pressure sensor (15) at the accumulator outlet monitors the outlet pressure of the emulsion pump (2) in real time, allowing for an assessment of its operating condition.

[0045] Specific application: The reverse emulsion filter device, automatic dosing device, and liquid supply station used in existing emulsion pumping stations are eliminated. Instead, an emulsion chamber (11) and an oil chamber (12) are created directly inside the frame (1). The automatic dosing device is divided into a dosing mechanism (3) and a detection unit for detecting the emulsion concentration, which are fixed on the frame (1), saving the occupied space. The installation of an inlet water filter (4), a suction filter (5), and a reverse emulsion filter (6) of a suitable type replaces the reverse emulsion filter device. This ensures the filtration of impurities such as metal or rubber particles during the stages of emulsion preparation, feeding, and return, saving the space occupied by the reverse emulsion filter device and automatic dosing device.This allows the entire emulsion pumping station to adapt to operate in a wider range of environmental conditions.
