Description

Technical Field

[0001] This utility model relates to the field of liquid quality testing, specifically to a liquid flow rate testing device. Background Technology

[0002] In the chemical industry, many solutions are involved in production processes, and the filtration flow rate of these solutions plays a crucial role in various aspects of chemical production. In the field of digital inkjet ink preparation, the filtration flow rate of liquid raw materials and ink is a vital parameter for verifying the quality of raw materials and ink. Impurities in the ink and raw materials (insoluble matter, gels, etc.) are a significant cause of slow filtration speeds. By detecting the filtration flow rate of liquid raw materials and ink, the quality of the ink and raw materials can be well understood.

[0003] However, existing technologies for measuring the flow rate of liquid raw materials and ink filtration typically require manual extraction of small batches of liquid and waiting for filtration. When testing large quantities of raw materials / ink, the operation is not only complex and time-consuming, but the manual timing also introduces errors into the test data. Therefore, the problems with existing technologies are their operational complexity and inaccurate quality monitoring of ink and raw materials. Utility Model Content

[0004] The purpose of this invention is to provide a liquid flow rate detection device to solve the problems of complex operation and inaccurate detection in existing flow rate detection technologies.

[0005] To achieve the primary objective of this invention, a liquid flow rate detection device is provided, comprising a frame, a liquid extraction module, a recording module, and a control module. The control module controls the operation of the liquid extraction and recording modules, all of which are mounted on the frame. The liquid extraction module includes at least one storage tank, a filtration instrument, and a filter. The storage tank includes a negative pressure air channel, a feed inlet, and a solution storage chamber. The filtration instrument includes a connection port, and the filtration instrument is connected to the storage tank via the negative pressure air channel and the connection port. The feed inlet is used for liquid injection, the solution storage chamber is used for solution storage, and the filter is used for solution filtration. The recording module includes at least one timer and at least one weighing instrument. The storage tank can be placed on the weighing instrument, which is used to detect the mass of the solution in the solution storage chamber, and the timer is used for timing.

[0006] The technical effect achievable by the above solution is the automation of liquid flow rate detection. This solution primarily controls the operation of the pumping and recording modules through the control module of the liquid flow rate detection equipment. When the pumping module is working, the negative pressure created in the storage tank enables automatic liquid pumping and feeding. Simultaneously, the recording module automatically weighs and times the liquid, displaying the filtration time result on the timer. The entire process is automated, eliminating the need for manual pumping and sampling. This allows for rapid detection and data display of liquid filtration flow rate, reducing issues such as individual operational differences and reading delays caused by manual operation and counting.

[0007] A further proposed solution is to use a stainless steel storage tank, a vacuum pump as the filtration instrument, and an electronic scale as the weighing instrument.

[0008] In the above scheme, the stainless steel storage tank can withstand negative pressure, ensuring the stability of the liquid storage function. Vacuum pump filtration is a mature technology that can be purchased directly from the market, resulting in low equipment manufacturing costs. Electronic scales offer precise technology and are easy to control.

[0009] A further proposed solution is to have at least two timers, storage tanks, and weighing instruments, all of the same number, arranged in sequence.

[0010] The above scheme incorporates multiple timers, liquid storage tanks, and weighing instruments, enabling simultaneous parallel and non-interfering filtration rate tests on the same horizontal plane, thus improving work efficiency.

[0011] A further embodiment includes a cover and a drain port in the storage tank. The negative pressure gas channel and the feed port are both located on the cover and are connected to the solution storage chamber. The drain port is located on the tank body of the storage tank.

[0012] The cover in the above design can be opened for easy cleaning of the inside of the storage tank. The drain port is used to drain liquids from the storage tank, such as cleaning fluid, ink, or raw materials. Ink / raw materials can be discharged back into the original solution or used for further testing via a pipeline connected to the drain port. Cleaning fluid can be discharged to a waste liquid recycling facility.

[0013] A further solution is to install a drain port for the weighing instrument on the corresponding frame below the weighing instrument.

[0014] The liquid drain port of the weighing instrument in the above scheme is used to drain the liquid in time when there is an accidental liquid leakage during operation, so as to prevent corrosive liquid from damaging the weighing instrument.

[0015] A further design includes a pressure gauge and a pressure relief tube on the cover. The pressure gauge is used to detect the pressure in the solution storage chamber, and the pressure relief tube is connected to the solution storage chamber.

[0016] The pressure gauge in the above scheme is used to monitor and provide feedback on the vacuum level in the storage tank in real time, and the pressure relief pipe is set up to connect to the ambient air pressure when material needs to be discharged or in an emergency, so as to ensure the safety of the equipment.

[0017] A further option is to provide a filter housing cavity on the feed inlet, which is used to house the filter.

[0018] The filter in the above scheme is set at the feed inlet, and filtration is achieved during the feeding process. The filter can be filter paper, eliminating the need for an external filter. The structure is simple and saves space.

[0019] A further proposed solution is to install a feed switch at the end of the filter housing that is away from the solution storage chamber.

[0020] As can be seen from the above scheme, when the vacuum filtration instrument stops working, there is still solution residue in the filter. By setting the feed switch, the vacuum filtration instrument can be turned off at the same time after the target quality is reached and the timing is stopped. The residual negative pressure in the containment chamber ensures that there is no liquid residue in the filter.

[0021] A further solution is to connect a spherical safety bottle between the negative pressure air passage and the connection port.

[0022] The spherical safety bottle in the above scheme can prevent foam from entering the filtration instrument.

[0023] A further option is that the liquid flow rate detection device also includes a protective sleeve, which is located on one side of the weighing instrument, and the liquid storage tank can be placed inside the protective sleeve.

[0024] The above solution can prevent vibration from damaging the weighing instrument during transportation. When not in use, the liquid storage tank is placed inside the protective sleeve.

[0025] A further solution is to install a cushioning pad inside the protective sleeve, so that when the liquid storage tank is placed inside the protective sleeve, the cushioning pad is located below the liquid storage tank.

[0026] The buffer pad in the above scheme can prevent damage to the liquid storage tank and the protective cover.

[0027] A further option is to also include at least one omnidirectional wheel and a handle on the frame.

[0028] The above solution makes the liquid flow rate detection device of this utility model mobile, which is not only suitable for laboratories, but also for warehouses and places where materials or products are stored in online production. It is easy to store and move, has a wider range of applications, and is more convenient to use.

[0029] A further option is that the control module includes a control box, which is equipped with a main power switch, a timer reset button, a start / stop button, and a quantitative weighing control panel.

[0030] A further option is that the filtration instrument also includes a gas path solenoid valve and an electrical socket, both of which are located on the control box and controlled by the control module.

[0031] In the above scheme, the main power switch is used to control the entire liquid flow rate detection equipment. Pressing the timer reset button resets the timer to zero for the next test. When the start / stop button is pressed, the timer starts. When the start / stop button is pressed again manually or the weight reaches the target, the timer stops. This allows for both automatic and manual timing control. The quantitative weighing control panel is used to set the weight and monitor the weight in real time. When the measured weight reaches the target weight, the gas circuit solenoid valve is disconnected to stop filtration and timing.

[0032] A further option is that the frame includes a placement plate, which is positioned below the weighing instrument, and the filtration instrument is placed on the placement plate.

[0033] The placement of the plate in the above scheme divides the liquid flow rate detection device into two layers, effectively utilizing space and ensuring stable movement. Attached Figure Description

[0034] Figure 1 This is a schematic diagram of the structure of a liquid flow rate detection device according to this utility model.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] See Figure 1 The liquid flow rate detection device provided in this embodiment includes a frame 5, a liquid extraction module, a recording module, a control module, and a protective sleeve 6. The control module is used to control the operation of the liquid extraction module and the recording module. The liquid extraction module, the recording module, and the control module are all mounted on the frame 5.

[0037] The liquid extraction module includes at least one liquid storage tank 1, a filtration instrument and a filter. In this embodiment, there are two liquid storage tanks 1, and the filtration instrument is a vacuum pump (not shown in the figure). The vacuum pump is a commercially available vacuum pump.

[0038] The storage tank 1 is made of stainless steel, which allows it to withstand negative pressure and ensures the stability of its storage function. The storage tank includes a cover 11 and a solution storage chamber, which is the internal storage space of the tank. A negative pressure air channel 12, a feed inlet 13, a pressure relief pipe 14, and a pressure gauge (not shown in the figure) are all located on the cover 11, while a drain outlet (not shown in the figure) is located on the tank body. The negative pressure air channel 12, feed inlet 13, and pressure relief pipe 14 are all connected to the solution storage chamber. The pressure gauge is used to monitor and provide feedback on the vacuum level in the storage tank in real time. The pressure relief pipe is used to connect to the ambient air pressure when discharge is needed or in an emergency, ensuring equipment safety. A filter housing 131 is provided on the feed inlet 13 to house a filter. The filter is located at the feed inlet 13, achieving filtration during the feeding process. The filter can be filter paper, eliminating the need for an external filter, resulting in a simple structure and space-saving design. Preferably, a feed switch (not shown in the figure) is provided at the end of the filter housing 131 away from the solution storage chamber. When the filtration instrument stops working, the feed switch is closed at the same time, and the residual negative pressure in the solution storage chamber ensures that there is no liquid residue in the filter.

[0039] The filtration apparatus (not shown in the figure) includes a connection port, a gas path solenoid valve, and an electrical socket. The filtration apparatus is connected to the liquid storage tank 1 via a negative pressure gas channel 12 and the connection port. Preferably, a spherical safety bottle is connected between the negative pressure gas channel and the connection port to prevent foam from entering the filtration apparatus. The electrical socket is used to power the filtration apparatus. The gas path solenoid valve is connected between the negative pressure gas channel 12 and the connection port and is used to control the connection and disconnection of the gas path. The gas path solenoid valve is a commercially available common gas path solenoid valve. In this embodiment, there are two gas path solenoid valves, which are respectively connected between the connection port and the negative pressure gas channels 12 of the two liquid storage tanks 1. The two gas path solenoid valves are independent of each other and do not affect each other.

[0040] The recording module includes at least one timer 3 and at least one weighing instrument 2. In this embodiment, the weighing instrument 2 is an electronic scale. A storage tank 1 can be placed on the weighing instrument 2. The weighing instrument 2 is used to detect the mass of the solution in the storage chamber, and the timer 3 is used for timing. In this embodiment, there are two timers 3 and two weighing instruments 2, and the two recording modules are arranged side-by-side. Preferably, each weighing instrument 2 is provided with a protective frame 21 to protect the weighing instrument 2 and the storage tank 1 located on the weighing instrument 2, preventing the storage tank 1 from moving. More preferably, a weighing instrument drain port (not shown in the figure) is provided on the frame below the weighing instrument 2 to promptly drain any liquid leakage caused by accidental operation, preventing corrosive liquid from damaging the weighing instrument 2.

[0041] The control module includes a control box 4, which is equipped with a main power switch 41, a timing reset button 42, a start / stop button 43, and a quantitative weighing control panel 44. The pneumatic solenoid valve and electrical socket are both located on the control box and controlled by the control module. The main power switch 41 controls the entire liquid flow rate detection equipment and controls whether the electrical socket is connected to power. Pressing the timing reset button 42 resets the timer for the next test. Timing begins when the start / stop button 43 is pressed and stops when the start / stop button 43 is pressed again manually or when the target weight is reached. This allows for both automatic and manual timing control. The quantitative weighing control panel 44 is used to set the weight and monitor it in real time. When the measured weight reaches the target weight, the pneumatic solenoid valve is disconnected to stop filtration and timing.

[0042] The frame 5 includes a placement plate 51, a handle 52, and casters 53. The placement plate 51 is positioned below the weighing instrument 2, and the filtration instrument is placed on the placement plate 51. The placement plate 51 allows the liquid flow rate detection device to be arranged in two layers, solving space issues and ensuring stable movement. The handle 52 and casters 53 enable the liquid flow rate detection device to be moved, making it suitable not only for laboratories but also for warehouses and online production facilities where materials or products are stored. This facilitates storage and movement, broadens its application scenarios, and makes it more convenient to use.

[0043] A protective sleeve 6 is disposed on one side of the weighing instrument 2. In this embodiment, there are two protective sleeves 6, each corresponding to one of the two weighing instruments 2. A liquid storage tank 1 can be placed inside the protective sleeve 6. A buffer pad (not shown in the figure) is disposed inside the protective sleeve 6. When the liquid storage tank 1 is placed inside the protective sleeve, the buffer pad is located below the liquid storage tank 1. To prevent damage to the weighing instrument 2 due to vibration during transportation, the liquid storage tank 1 is placed inside the protective sleeve 6 when not in operation. The buffer pad prevents damage to the liquid storage tank 1 and the protective sleeve 6 during movement.

[0044] The working principle of the liquid flow rate detection device in this embodiment is as follows: When liquid filtration flow rate detection is required, the liquid flow rate detection device is pushed to the location of the solution to be tested, and the storage tank 1 is moved from the protective sleeve 6 to the weighing instrument 2. The feed inlet 13 is connected to the solution to be tested through a pipeline, and the negative pressure air channel 12 is connected to the connection port of the vacuum filtration instrument through a pipeline, on which a gas solenoid valve is installed. After installation, the main power switch 41 is turned on, the vacuum filtration instrument starts working but the gas solenoid valve is closed. The weight is set through the quantitative / weighing control panel 44 and the start / stop button is pressed. The gas solenoid valve is opened to perform vacuum filtration. When the weighing instrument 2 displays the weight, the timing stops and the test time is retained. At the same time, the feed switch is closed to stop feeding, the vacuum filtration instrument stops working and the gas solenoid valve is closed. The residual negative pressure cleans the solution in the filter, and the timer displays the timing duration. The flow rate can be obtained based on the duration and weight, thus completing the vacuum filtration flow rate detection. After the test is completed, the solution in storage tank 1 can be drained back into the original solution or used for the next test through the drain port connection pipe. Pressing the timer reset button 42 will reset the timer. After turning off the main power switch 41, the storage tank 1 can be placed back into the protective cover 6. The cover 11 of storage tank 1 can also be opened later to clean the storage tank 1.

[0045] The liquid flow rate detection device in this embodiment is controlled by a control module. Utilizing the pressure difference in the storage tank 1, it automatically draws and feeds the liquid, automatically weighs and times the flow, and displays the filtration flow rate result on the timer 3. The entire process is automated, eliminating the need for most manual drawing and sampling operations. The solution in this embodiment can be directly drawn from the product pool for testing without additional sampling. This allows for rapid detection and data display of liquid filtration flow rate, reducing issues such as individual differences in operation and reading delays caused by manual operation and counting. Two independent sets of timers 3, storage tank 1, and weighing instrument 2 are arranged side-by-side, enabling parallel and non-interfering filtration rate testing on the same horizontal plane, thus improving work efficiency.

[0046] The above embodiments are merely preferred examples of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles of this utility model patent application should be included within the scope of this utility model patent application.
