Description

barrel pump Technical Field

[0001] This invention relates to the field of fluid extraction, and in particular discloses a barrel pump that is smaller in size, lower in noise, safer, more reliable, more convenient, longer in life, and more intelligent than traditional barrel pumps. In particular, the intelligent control saves labor costs, and the automatic metering of extraction is more convenient and effective. Background Technology

[0002] Traditional manual barrel pumps use a reciprocating pump structure, which is particularly time-consuming and labor-intensive, requiring a high level of physical strength from the operator. Moreover, the pumping process is noisy and vibrates a lot, and the wear and tear during pumping leads to a short lifespan for the piston cup, resulting in frequent machine malfunctions.

[0003] Traditional manual drum pumps use a vane pump structure, which increases the labor cost of replacing the vanes after they wear out over time.

[0004] There is always residual liquid in the eccentric cavity of the vane pump. Although it provides pressure for suction, the hazard caused by the residual liquid in the upper part of the pump evaporating into the air after the operation is over may be greater.

[0005] Traditional electric drum pumps use an axial flow pump + long shaft + motor drive. Due to the excessive length of the motor shaft, they are prone to deformation and damage, and are also difficult to process, resulting in high overall costs.

[0006] In particular, the large motor, positioned at the top of the pump, makes it noticeably top-heavy and prone to tilting, causing the bottom part to detach from the bottom of the tank, resulting in incomplete pumping. This problem is also evident in vane pumps, whether hand-cranked or electric.

[0007] When dealing with liquids with high viscosity, this method requires the use of a high-power motor, resulting in a larger motor size, a top-heavy design, and a more serious problem of incomplete tilting.

[0008] Meanwhile, prolonged use at an angle may cause the motor bearings to become misaligned, reducing their service life.

[0009] These traditional electric tank pumps have a very low level of intelligence. They only solve the problem of replacing manual operation with machines, but they do not manage the pumping flow rate and operation process data, and lack anti-theft protection, resulting in property losses for owners.

[0010] In addition, this type of axial flow pump + long shaft + motor drive has many components and is very complex, making it difficult for users to disassemble and maintain.

[0011] All of the above-mentioned pump structures have shaft leakage, which can cause the liquid inside the tank to contaminate the motor or pollute the surrounding environment.

[0012] Linear fluid technology, also known as linear pumps, was first documented in patent ZL2012104365922, issued in November 2012, which discloses the key features of the technology in terms of its basic principles. However, its specific features were not disclosed when used in the scenario of extracting liquid from a container.

[0013] This invention is based on linear fluid technology and aims to achieve the following main characteristics of linear pumps: zero leakage, small size, low noise, long submersion time, high efficiency, easy disassembly and assembly, easy maintenance, and intelligent operation. It further discloses the structural features of the pump body and the intelligent control method. Summary of the Invention

[0014] This invention mainly addresses many issues related to the small size, long lifespan, low noise, zero leakage, safety, convenience, easy disassembly and assembly, easy maintenance, and high level of intelligence of liquid extraction devices, as well as how to achieve intelligent management.

[0098] According to the three-dimensional schematic diagram of the bucket pump in Figure 1 of the present invention, after ensuring that the battery power of the drive box (7) is sufficient, the lower end of the bucket pump is inserted into the bucket. After the start / stop button of the drive box is pressed for the first time, the liquid in the bucket enters from the filter (2) and reaches the pump body (3). Since the stator assembly of the pump body is energized, the rotor assembly rotates accordingly, lifting the liquid to the output pipe and discharging it from the output port (8). If the start / stop button of the drive box is pressed again, the operation will stop immediately.

[0099] According to the technical feature diagram of the present invention, Figure 2 shows a schematic diagram of the axial center section of the pump body. The vector current of the drive box enters the pump body terminal (308) through the conduit (4) and the cover (6). The winding (302) of the stator assembly is energized, and a rotating electromagnetic field is generated immediately. The magnetic force penetrates the sleeve (305) and interacts with the magnetic sensing / permanent magnet structure (312) of the rotating drum, thereby causing the rotating drum (311) to rotate. The rotating drum drives the input spiral ring (313) to rotate synchronously. After the liquid is rectified by the input cover (301), it is pressurized and gains energy under the rotation of the input spiral ring. The liquid enters the stationary guide ring (310). The rotating liquid is turned into axial forward movement and is pressurized again to gain energy. It then enters the output spiral ring (309) and gains secondary pressurization. The liquid then enters the guide structure of the output cover and gains energy again. It is then discharged from the output port of the output pipe (5).

[0100] The core rod (307), guide ring, input cover, output cover, winding, and iron core form a stationary body that limits the rotor assembly and ensures that it operates within a certain constraint range.

[0101] As shown in Figure 3, a three-dimensional schematic diagram of the filter nozzle according to the technical features of this invention, after the filter nozzle is installed on the pump body, it bears most of the weight of the pump via the grounding foot (12). The liquid first passes through the filter hole (11) of the filter nozzle and then enters the inlet cover of the main body. The more filter holes there are, the greater the flow rate of the fluid flowing through the filter holes, or the larger the diameter of the filter holes, the greater the flow rate. If the diameter of the filter holes exceeds half the inlet diameter of the pump body, then the filtering is meaningless.

[0102] The filter nozzle installation structure (13) is detachable and connected to the pump body, which improves the maintainability of the tank pump. In particular, when the filter nozzle is stuck or blocked by a large foreign object, it must be removed, handled separately, and restored before it can be reassembled.

[0103] The grounding feet of the filter nozzle contact the bottom of the container and are made of a specific material with vibration-absorbing properties to reduce resonance that may occur in rotating parts. The more grounding feet there are, the larger the contact area with the bottom of the container, the greater the anti-slip force, and the better the ability to resist the overall tilting of the container pump.

[0104] According to the technical features of the present invention, Figure 4 shows a three-dimensional schematic diagram of the drive box, and Figure 5 shows a low-view transparent schematic diagram of the drive box. The drive box's slot (74) is fixed to the output tube, the battery (77) is installed inside the drive box, the battery cover (71) is closed, and the start / stop button (721) on the panel is touched, then the pump body is powered on and starts to work.

[0105] The fixing of the card holder (74) to the output tube relies on the elasticity of the snap ring (743) and the cooperation of the snap ring (742) and the slot (741). The width of the snap ring is smaller than the diameter of the output tube, and the diameter of the slot is smaller than or equal to the diameter of the output tube, which is conducive to the tight fit between the card holder and the output tube.

[0106] If the spring force of the retaining ring can be overcome manually, it can be moved up and down manually, that is, the drive box moves up and down with the retaining seat, thus meeting different barrel height requirements and facilitating disassembly and assembly before and after transportation.

[0107] It uses an external power frequency adapter, which is plugged into the power input port of the driver box to directly supply power for liquid extraction, and can also automatically charge the battery.

[0108] If the battery is fully charged, the pump can be moved and used freely without the power supply of the mains frequency adapter.

[0109] The driver and the battery are two independent units of the driver box, which can be fixed in a detachable and assembled manner. If the pump is to be used for a long time and the required battery power is insufficient, a larger capacity battery can be replaced and the pump can be reassembled for continued use.

[0110] According to the technical feature diagram of the present invention, Figure 6 shows the function of the driver box panel. The start / stop button on the driver box panel can be manually touched directly, or it can be connected to a mobile phone via USB interface (722) or WIFI wireless connection, and can be started automatically or by gesture using a mobile APP program.

[0111] The display window on the driver box panel is a dialogue window between the user and the tank pump. It displays online status and target value information. It can also be connected to a mobile phone via USB interface (722) or WIFI wirelessly to view the information in the display window using a mobile APP.

[0112] For low-end users, a simple digital or indicator light display is sufficient.

[0113] For high-end users, the display window uses an LCD display or a mobile phone screen display via a mobile APP.

[0114] To protect user assets, the driver box has a password disk. Only after passing the password via numeric password, fingerprint password, or voice password can the next step be performed. Alternatively, it can be passed via facial recognition, emoji password, or gesture password through the mobile APP. Once the anti-theft auto-start program is activated and unauthorized power-on is detected, the power can be remotely and automatically cut off immediately.

[0115] According to the technical feature of the present invention, Figure 7 shows a three-dimensional schematic diagram of the cover seat. The material of the cover seat has a certain mechanical elasticity. Therefore, the output tube can be squeezed into the cover seat notch (62) by external force and fit with the inner wall (63) of the cover seat. Moreover, the diameter of the inner wall of the cover seat is less than or equal to the diameter of the output tube. The elastic rebound force of the cover seat is used to achieve a tight fit.

[0116] The diameter of the outer wall (61) of the cover seat is larger than that of the bucket lid so that it will not fall into the bucket. Moreover, the step (65) of the cover seat faces downward and fits tightly with the lid opening of the bucket, so as to achieve the stability of the cover seat installation and avoid the possibility of the cover seat being moved by the output pipe, thereby improving the safe use of the bucket pump.

[0117] The cover material has a certain degree of elasticity, which absorbs the resonance energy that may come from the output pipe and prevents the barrel from resonating.

[0118] Multiple slots (64) are used for the cover seat, one of which is used for the conduit to pass through, and the rest are used for the liquid level to drop during the working process to automatically draw air into the tank.

[0119] As shown in Figure 8, a three-dimensional schematic diagram of the output tube according to the technical features of this invention, the output tube is formed in one piece from a rigid material, so that it can be directly inserted into the liquid in the tank, reaching the bottom of the tank, to ensure thorough extraction.

[0120] The inner diameter of the output pipe is greater than or equal to the inner diameter of the pump body's output port, and the radius of the bend is greater than three times the diameter of the output pipe. This reduces the flow resistance of the liquid flow process, including the output pipe, thereby increasing the flow velocity.

[0121] The height of the output pipe must be greater than the height of the tank in order to extract and discharge the liquid.

[0122] The lower end of the output pipe has a detachable structure, including at least threaded, snap-fit, and slotted types, to facilitate on-site installation of the pump body and convenient transportation of the tank pump.

[0123] The output structure features a detachable design, including at least threaded, snap-fit, and slotted types, to facilitate on-site installation and connection with external devices, achieving convenient use.

[0124] According to the technical features of this invention, Figure 9 shows the electrical working principle block diagram of the barrel pump. After the power frequency adapter (A1) is turned on, the current enters the power management module (B), forming different required working voltages to supply power to each module. After the microcontroller CPU circuit (C) is powered on, it immediately performs a self-test. If there are no abnormalities, it enters standby mode. When the start / stop button is touched for the first time, or after the communication radio frequency circuit (F) receives the start command, the CPU immediately sends an input alternating signal of vector current. After receiving the alternating signal, the drive circuit (D) sends vector current into the pump stator, that is, an alternating magnetic field is formed. This alternating magnetic field is transmitted to the magnetic field torque zone of the linear pump rotor, synchronously rotating and propelling the fluid.

[0125] When the battery (A2) is low on power, the power adapter is turned on, and the battery will automatically recognize the low power and start charging until charging is complete. Then the charging power will be automatically cut off to ensure that the battery has enough power to be ready for standby at any time.

[0126] When the pressure sensor (E) senses a signal exceeding a preset value, the CPU adjusts the alternating frequency of the input signal to the drive circuit, thereby adjusting the current of the drive circuit to adjust the speed and torque of the pump body rotor assembly, thus adjusting the working state and achieving the target sampling value to reach the expected value, thereby protecting other devices in the fluid process.

[0127] When it is necessary to set the target flow parameters, the operation input circuit and display driver circuit (G) will start automatically and track the set parameters and actual usage parameters in real time. The online parameters will be fed back to the display driver circuit or stored in the storage chip of the microcontroller CPU circuit for easy access at any time.

[0128] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the present invention claims.
