Abrasive jet technology comprises a front mixing technology and a rear mixing technology, most of the abrasive jet technologies used for cutting casing pipes, pile legs and the like at present are rear mixing technologies, and the rear mixing technologies have the defects of uneven sand mixing, more gas phases in cutting water beams and the like, so that the cutting efficiency is low. The front mixing type abrasive jet cutting technology is that the abrasive is firstly mixed with liquid in a high-pressure tank and then is pressurized and conveyed to a nozzle. By adopting the front mixing mode, the liquid and the abrasive are mixed most uniformly, the energy obtained by the abrasive particles is also the highest, and the operation effect is the best. Abrasive jet cutting techniques are generally in the ultra-high pressure range, and particularly the pressure of the premixed abrasive jet cutting technique is generally in excess of 2000 bar. The front mixing type abrasive jet technology is less in application, the front mixing type abrasive jet technology with few applications has the defect that the sand adding process needs to be stopped, even if the technology without stopping exists, the whole sand adding mechanism is complex in design, a high-pressure area and a low-pressure area need to be effectively separated in the sand adding mechanism, the instability is high, and once the high-pressure area and the low-pressure area cannot be effectively separated, the whole sand adding mechanism loses the due functions.

At least one embodiment of this disclosure provides a sand mixing device, this sand mixing device includes M sand mixing tank, M pipeline and controller, and every sand mixing tank is provided with inlet and liquid outlet. M conveying pipeline includes M input pipeline and M output pipeline, and M input pipeline is connected with M sand mixing tank's inlet respectively to provide high-pressure liquid for M sand mixing tank respectively. M output pipelines are respectively connected with the liquid outlets of the M sand mixing tanks to respectively output the sand mixing liquid in the sand mixing tanks. Each input pipeline is provided with a first valve, and each output pipeline is provided with a second valve. The controller is in communication connection with the first valves and the second valves of the M conveying pipelines, and M is an integer greater than or equal to 2.

Fig. 1 shows a schematic diagram of a sand mulling device provided by at least one embodiment of the present disclosure.

As shown in fig. 1, the sand mulling apparatus 100 includes M sand mulling tanks 110, M delivery lines, and a controller 130. Each sand mixing tank 110 is provided with a liquid inlet 111 and a liquid outlet 112. The M transfer lines include M input lines 121 and M output lines 122. The M input pipelines 121 are respectively connected with the liquid inlets 111 of the M sand mixing tanks to respectively provide high-pressure liquid for the M sand mixing tanks 110. The M output pipelines 122 are respectively connected to the liquid outlets 112 of the M sand mixing tanks to respectively output the sand mixing liquid in the sand mixing tank 110. Each input line 121 is provided with a first valve 1211 and each output line 122 is provided with a second valve 1221. The controller 130 is communicatively coupled to the first and second valves of the M delivery lines.

For example, M may be an integer greater than or equal to 2, and M is equal to 2 in some embodiments below, but the embodiments of the present disclosure are not limited thereto, and in other embodiments, M may also be equal to 3 or another integer greater than 2, and a value of M may be specifically determined according to actual needs.

For example, an input line 121, a sand mulling tank 110, and an output line 122 connected in series may form a mulling line. Taking a sand mulling line as an example, a first end of the input pipeline 121 may be connected to a liquid supply device, which may be a high pressure water source, for example, and a second end of the input pipeline 121 may be connected to the liquid inlet 111 of the sand mulling tank 110. In the case that the first valve 1211 on the input line 121 is in the open state, the input line 121 may communicate the high-pressure water source with the sand mixing tank 110, and the high-pressure water provided by the high-pressure water source may enter the sand mixing tank 110 through the input line 121. Conversely, with the first valve 1211 on the input line 121 in the closed state, the high-pressure water source may be disconnected from the sand mixing tank 110.

For example, a first end of the output line 122 is connected to the liquid outlet 112 of the sand mixing tank 110, a second end of the output line 122 may be connected to the high pressure nozzle, and the output line 122 may communicate the sand mixing tank 110 and the high pressure nozzle with the second valve 1221 on the output line 122 in the open state. Conversely, with the second valve 1221 on the outlet line 122 in the off state, the sand mixing tank 110 and the high-pressure nozzle may be disconnected.

For example, M delivery lines may be connected in parallel, and the first valve 1211 and the second valve 1221 on the same delivery line are turned on and off in the same state. Before the first valve 1211 is opened, sand may be injected into the sand mixing tank 110 in advance, and after the first valve 1211 is opened, high-pressure water enters the sand mixing tank 111 and is mixed with the sand in the sand mixing tank 111 to form a sand mixing liquid, which is a high-pressure abrasive suspension. The sand-mixing fluid flows out through the fluid outlet 112 of the sand-mixing tank 110 and reaches the high-pressure nozzle through the output pipeline 122 to be sprayed by the high-pressure nozzle for cutting operation. In the case where both the first valve 1211 and the second valve 1221 are in the open state, the sand mixing tank located between the two valves is in a high-pressure state; when both the first valve 1211 and the second valve 1221 are in the off state, the sand mixing tank located between the two valves is in the normal pressure state, and the normal pressure is the atmospheric pressure. In the disclosed embodiment, the abrasive material is a water jet cutting abrasive material, and the abrasive material is in the form of particles and is divided into a natural abrasive material (such as garnet abrasive material) and a man-made abrasive material (such as white corundum abrasive material).

For example, the first valve 1211 and the second valve 1221 may be controlled in a pneumatic, electric, or other manner, and the first valve 1211 and the second valve 1221 may be a pneumatic ball valve, for example.

For example, the controller 130 may be configured to control the on-off states of the first valve 1211 and the second valve 1221 of the M delivery lines to switch different sand mulling tanks to perform the mulling work.

For example, the controller 130 may be in communication connection with the first valve 1211 and the second valve 1221 on each of the delivery lines in a wired or wireless manner to transmit control instructions to each of the first valve 1211 and the second valve 1221. The controller may be implemented as a hardware device such as a microprocessor, a Central Processing Unit (CPU), a hardware circuit, which may be a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), a system on a chip, a system on a substrate, an Application Specific Integrated Circuit (ASIC), or any other reasonable manner of hardware or firmware for integrating or packaging a circuit.

The sand mulling device of the embodiment of the disclosure can form a plurality of sand mulling lines, and can control the opening and closing of each sand mulling line through the controller, so that different sand mulling lines can be switched to provide sand mulling liquid for the high-pressure nozzle in the sand mulling operation process, and continuous operation is realized. And, under a sand mulling line open mode, the sand mulling jar on another sand mulling line that is in the closed state is in the ordinary pressure state, and then can realize the ordinary pressure and add sand, that is to say, based on this sand mulling device, can realize not shutting down and add sand, improved the efficiency of sand mulling operation to simple structure, stability is good.

Fig. 2 shows a schematic view of another sand mixing device provided in at least one embodiment of the present disclosure.

As shown in fig. 2, for example, the sand mulling apparatus may further include M pressure relief lines 140, the M pressure relief lines 140 are respectively communicated with the M output lines 122, and each pressure relief line 140 is provided with a third valve 141.

For example, in a normal operation state, the third valve 141 may be in a shut-off state. When a pressure build-up occurs due to a blockage in a sand mixing line, the third valve 141 may be controlled to switch from the off state to the on state to release the pressure in the line. For example, the third valve 141 may be controlled pneumatically, electrically, or otherwise.

For example, the on/off state of the third valve 141 may be automatically controlled by the controller 130, and the controller 130 may be communicatively connected to the M third valves 141 to send control signals to the third valves. Each of the output pipes 122 may be further provided with a pressure detecting device for detecting an internal pressure of the output pipe 122. The pressure detection device is communicatively connected to the controller 130 and may transmit the detected internal pressure to the controller 130, and when the controller determines that the internal pressure of a certain output line is higher than the predetermined pressure, the controller may control the third valve 141 corresponding to the output line to open to release the internal pressure of the output line.

For example, for each outlet line 122, the connection location of outlet line 122 to pressure relief line 140 is closer to outlet port 112 than the location of second valve 1221. In this way, the pressure relief may be performed with the second valve 1221 in the off state, for example, after the first valve 1211 and the second valve 1221 are both closed, if a pressure build-up exists in a line between the first valve 1211 and the second valve 1221, the pressure relief may be performed through the pressure relief line 140.

Fig. 3 shows a schematic view of another sand mixing device provided in at least one embodiment of the present disclosure.

As shown in fig. 3, for example, each sand mixing tank 110 is integrated with the first valve 1211 and the second valve 1221 of the connected conveying line in one module to form M sand mixing modules. For example, in case the output line is connected to the third valve 141, each sand mixing tank 110 is integrated with the corresponding first valve 1211, second valve 1221 and third valve 141 into one module.

For example, the first valve 1211, the sand-blending tank 110, the second valve 1221 and the third valve 141 connected to the upper one of the conveying lines shown in fig. 3 are integrated into one module M1, and the first valve 1211, the sand-blending tank 110, the second valve 1221 and the third valve 141 connected to the lower one of the conveying lines are integrated into another module M2. The integration into a module may be formed in a unitary structure, e.g. the various components of the module are combined in a housing and interfaced with the outside. Each module is relatively independent.

For example, based on the way that the sand mixing tank and the corresponding valve are integrated together, the external connecting pipelines of each module are less, and the occupied space of the whole equipment is less compared with the way that a plurality of valves are integrated into a single independent module.

Fig. 4 shows a schematic view of another sand mixing device provided in at least one embodiment of the present disclosure.

As shown in fig. 4, for example, the first valves 1211 and the second valves 1221 of the M transfer lines are integrated in one module to form a switching module independent of the M sand mulling tanks.

For example, the plurality of first valves 1211, the plurality of second valves 1221 and the plurality of third valves 141 are all integrated in the module M3, and the advantage of separately integrating the components having the switching function into one module is that the internal piping of the module in which each sand mixing tank is located is relatively reduced, the arrangement of components is convenient, and the field layout of the equipment is relatively flexible.

For example, the controller 130 is further configured to: the first valves 1211 controlling the M input lines are alternately opened and closed, and the on-off states of the first valves 1211 and the second valves 1221 controlling each of the delivery lines are identical to perform the sand mulling work alternately using the M sand mulling tanks 110.

For example, taking M as 2 as an example, the M input pipelines include a first input pipeline and a second input pipeline, the M sand mulling tanks include a first sand mulling tank and a second sand mulling tank, and the M output pipelines include a first output pipeline and a second output pipeline. The first input pipeline, the first sand mixing tank and the second output pipeline are sequentially connected, and the second input pipeline, the second sand mixing tank and the second output pipeline are sequentially connected. Before the sand mulling operation starts, sand materials can be injected into the first sand mulling tank and the second sand mulling tank in advance, and after the sand mulling operation starts, the controller can control the first valve on the first input pipeline and the second valve on the first output pipeline to be opened first, and the first sand mulling tank is utilized for the sand mulling operation. After the first sand mulling tank works for a period of time, the first valve on the first input pipeline and the second valve on the first output pipeline can be closed, and the first valve on the second input pipeline and the second valve on the second output pipeline are simultaneously opened so as to switch to the second sand mulling tank for mulling work. During the operation of the second sand mixing tank, sand materials can be supplemented to the first sand mixing tank, and after the second sand mixing tank operates for a period of time, the first sand mixing tank is switched back, so that the circulation can realize long-time continuous operation. Similarly, for the case that M is an integer larger than 2, the sand mixing tanks can be operated alternately by controlling the valves on the plurality of input pipelines to be opened and closed alternately.

For example, in some embodiments, the sand mulling apparatus may further include a feeding assembly that may be connected to the M mulling tanks 110 to deliver sand to the M mulling tanks, respectively.

Fig. 5 shows a schematic view of another sand mixing device provided in at least one embodiment of the present disclosure. As shown in FIG. 5, for example, the loading assembly may include a loading tank 151 and M fourth valves 152 connecting the loading tank to the M sand mixing tanks 110, respectively. In addition, the charging assembly may further include a power unit such as a charging pump, and the sand in the charging tank 151 may be pumped into the corresponding sand mixing tank 110 when the fourth valve is opened. For example, the fourth valve 152 may be controlled pneumatically, electrically, or otherwise.

For example, the controller 130 is communicatively coupled to the feeding assembly, e.g., the controller 130 is communicatively coupled to the M fourth valves to control the on-off states of the M fourth valves. The controller is further configured to: the feed assembly is controlled to deliver sand to the sand mixing tank 110 in an inactive state. For example, for a sand mixing tank in a non-operating state, a fourth valve connected to the sand mixing tank may be controlled to open, so that sand in the feed tank 151 is added to the sand mixing tank, and the sand mixing tank 110 is refilled with sand.

For example, in some embodiments, the sand mulling apparatus may further include a detection component configured to detect an amount of remaining sand in the M sand mulling tanks 110.

Fig. 6 shows a schematic view of another sand mixing device provided in at least one embodiment of the present disclosure. As shown in fig. 6, for example, the detection means may include M first flow meters 161 respectively disposed on the M input pipes 121 and M second flow meters 162 respectively disposed on the M output pipes 122, the first flow meters 161 may measure the flow rates of the fluids in the corresponding input pipes 121, and the second flow meters 162 may measure the flow rates of the fluids in the corresponding output pipes 122. The signal values measured by the first flow meter 161 and the second flow meter 162 are transmitted to the controller, and the controller may determine the amount of remaining sand in the sand mixing tank, for example, from the front and rear flow rates. In one example, for each delivery line, the volume of water flowing into the sand mixing tank 110 can be determined according to the flow rate and the time length of the input line 121, the volume of the sand mixing fluid flowing out of the sand mixing tank 110 can be determined according to the flow rate and the time length of the output line 122, the subtraction result of the front and back fluid volumes can be regarded as the volume of the sand flowing out of the sand mixing tank 110, and the amount of sand remaining in the sand mixing tank 110 can be determined according to the total sand amount of the sand mixing tank 110 and the sand amount flowing out. Alternatively, in another example, in the case where the content of sand in the fracturing blender fluid is extremely high, the volume of the fracturing blender fluid flowing out of the fracturing blender jar 110 may be directly used as the volume of the output sand, and the remaining sand amount of the fracturing blender jar 110 may be determined.

For example, the M sand mulling tanks include a first sand mulling tank and a second sand mulling tank. The controller is further configured to: under the condition that the residual sand amount of the first sand mixing tank in the working state is less than the preset sand amount, controlling a first valve and a second valve of a conveying pipeline connected with the first sand mixing tank to be in a closed state from an open state so as to change the first sand mixing tank from the working state to a non-working state; and controlling a first valve and a second valve of a conveying pipeline connected with the second sand mixing tank to be changed from a closed state to an open state so as to change the second sand mixing tank from a non-working state to a working state.

For example, following the example where M is 2, the first sand mixing tank and the second sand mixing tank may be filled with sand in advance before the start of the sand mixing operation, and after the start of the sand mixing operation, the controller may control the first valve on the first input line and the second valve on the first output line to open to perform the sand mixing operation using the first sand mixing tank. During the operation of the first sand mixing tank, the flow in the first input pipeline and the flow in the first output pipeline are detected by using the corresponding first flow meter and the corresponding second flow meter, so that the residual sand amount in the first sand mixing tank can be determined according to the flow and the operation duration, when the residual sand amount in the first sand mixing tank is monitored to be smaller than a certain value, the residual sand amount in the first sand mixing tank is considered to be used up or the residual sand amount is small, and the operation can be switched to the second sand mixing tank. During operation of the second sand mixing tank, the first sand mixing tank may be replenished with sand material using a feed tank. And during the operation of the second sand mixing tank, the residual flow in the second sand mixing tank can be monitored, when the residual sand amount in the second sand mixing tank is monitored to be smaller than a certain value, the first sand mixing tank can be switched back to work, and after the first sand mixing tank is switched back to work, the charging tank 151 is used for replenishing sand materials to the second sand mixing tank, and the operation is circulated until the sand mixing operation is completed. Similarly, for the case that M is an integer larger than 2, the sand mixing tanks work in turn, during each sand mixing tank work, the residual sand amount in the sand mixing tank is monitored, when the residual sand amount is monitored to be small, the sand mixing tank is switched to work, sand materials are supplemented to the sand mixing tank in the previous non-working state, and the operation is circulated until the sand mixing work is completed.

For example, in other embodiments, the controller may be further configured to: under the condition that the working time of the first sand mixing tank in the working state is longer than the preset working time, controlling a first valve and a second valve of a conveying pipeline connected with the first sand mixing tank to be in a closed state from an open state so as to change the first sand mixing tank from the working state to a non-working state; and controlling a first valve and a second valve of a conveying pipeline connected with the second sand mixing tank to be changed from a closed state to an open state so as to change the second sand mixing tank from a non-working state to a working state.

For example, the remaining sand amount in the sand mix tank may be determined according to the operation time period, it may be detected in advance how long the sand mix tank filled with the sand material is operated and then the remaining sand amount may be smaller than a predetermined sand amount, and the detected time period may be taken as the maximum operation time period of the sand mix tank. For each sand mixing tank in the working state, the working time of the sand mixing tank can be monitored by using the controller, when the working time reaches the maximum working time, the sand mixing tank is switched to work, and sand materials are supplemented to the previous sand mixing tank in the non-working state.

For example, the controller is further configured to: and under the condition that the required flow of the sand mixing liquid is greater than the preset flow, controlling the first valves and the second valves of the at least two conveying pipelines to be opened so as to utilize the at least two sand mixing tanks to execute sand mixing work.

For example, under the condition that the required flow of the sand mixing liquid is large, two or more sand mixing tanks can be used for working at the same time, that is, the first valves and the second valves on two or more conveying pipelines are opened to meet the large flow demand, and the number of the opened conveying pipelines can be determined according to the required flow. In the case that the required flow of the sand mulling liquid is reduced, the sand mulling operation can be performed by switching to one sand mulling tank.
