Description

Technical Field

[0001] This utility model relates to the field of testing, and in particular to an automatic and precise liquid addition washing system. Background Technology

[0002] Currently, the common method for determining the free silica content in dust is the pyrophosphate method. A crucial step in this process is placing the sample in a filtration device and repeatedly adding water until the filtrate no longer shows acidity. The detection equipment used includes basic tools such as a funnel and beaker. The funnel supports and fixes the filter paper, while the beaker heats distilled water in the funnel to rinse impurities from the filter paper, thus purifying the silica. Because the liquid can only slowly penetrate the fine pores of the filter paper by gravity, forming a limited flow area only at the bottom of the funnel, this directly results in a slow filtration rate and low efficiency. During this process, a continuous supply of hot distilled water must be provided for rinsing to prevent the pyrophosphate from forming a difficult-to-filter gel when the temperature drops below 50°C. Furthermore, the water level must be kept at least two-thirds of the funnel's height, making the entire detection process both time-consuming and labor-intensive.

[0003] If a testing device with an automated and precise liquid addition system is designed, it can effectively improve the filtration efficiency of samples, shorten the filtration time, and reduce time and labor costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low efficiency, time and labor consumption when rinsing and filtering samples through inspection equipment, and to provide an automatic and precise liquid addition washing system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic and precise liquid-adding washing system is used on a testing instrument. The testing instrument includes a body with a water-adding station. The washing system includes a filtration device, a weighing device, and a spraying device mounted on the body. The filtration device includes a conveying mechanism and a filter container. The filter container is mounted on the conveying mechanism and is conveyed by the conveying mechanism to enter or leave the water-adding station. The spraying device and the weighing device are mounted on the water-adding station. The weighing device weighs the filter container and generates a sensing signal. The spraying device starts spraying into or stops spraying into the filter chamber of the filter container based on the sensing signal.

[0007] This invention's washing system transports filter containers to the water-filling station via a conveying mechanism. A weighing device measures the weight of the filter containers at the water-filling station in real time, generating a sensor signal. The spraying equipment automatically starts / stops water filling based on this signal. After water filling one filter container, the conveying mechanism moves the filter container away from the water-filling station and transports the next filter container to it. Compared to existing technologies, this washing system, when used on a testing instrument, achieves fully automated and precise water filling without manual operation, effectively improving efficiency.

[0008] Furthermore, the spraying equipment is located above the water filling station, and the weighing equipment is located below the water filling station, with their positions opposite each other. The weighing equipment includes a lifting mechanism and a weighing instrument. The weighing instrument is mounted on the lifting mechanism to rise or return to its original position under the drive of the lifting mechanism. When the filter container is conveyed to the water filling station, the filter container is lifted and weighed by the weighing instrument, and the spraying equipment sprays water onto the filter chamber of the filter container. In this solution, the spraying equipment is located above the water filling station, while the weighing equipment is located below the water filling station, with their positions opposite each other. This layout allows the spraying and weighing processes to proceed more smoothly, avoiding mutual interference. Through the combined use of the lifting support and the weighing instrument, it can be ensured that the filter container is stably supported and lifted during the weighing process, thereby improving the accuracy and stability of the weighing.

[0009] Furthermore, the conveying mechanism includes a turntable and a rotary drive mechanism. The output end of the rotary drive mechanism is connected to the center of the turntable, causing the turntable to rotate under the drive of the rotary drive mechanism. The turntable has at least one placement cavity that runs longitudinally through the turntable, and its bottom inner circumference has a support protrusion for supporting the filter containers. In this solution, the turntable is provided with several placement cavities for placing filter containers, thereby forming several filtration stations. The rotation of the turntable allows several filter containers to be queued for water filling. After each filter container has been filled, it can wait outside the water filling station for the next water filling. The water filling and waiting time can be adjusted by changing the turntable speed according to the testing needs, achieving efficient and flexible filter container transport and water filling operations.

[0010] Furthermore, the weighing equipment includes a lifting bracket, which is located at the upper end of the weighing instrument. The upper end of the lifting bracket has a lifting section, and the bottom of the filter container has a connecting groove adapted to the lifting section. The weighing instrument abuts against the filter container through the lifting section of the lifting bracket. In this design, when the lifting bracket supports the weighing instrument to rise, the lifting section and the connecting groove are engaged, and the two work together to ensure a stable connection between the weighing instrument and the filter container.

[0011] Furthermore, the lifting mechanism includes a lifting bracket and a lifting drive mechanism. The lifting bracket includes a support base, lifting guide rods, and a connecting seat. Two lifting guide rods are provided and longitudinally arranged on the support base. The connecting seat has a sleeve hole, through which the connecting seat can be lifted and lowered onto the lifting guide rods, so as to be lifted or lowered relative to the support base or reset under the drive of the lifting drive mechanism. This scheme is the specific structural design of the lifting bracket.

[0012] Furthermore, the exterior of the filter container is cylindrical. This design allows the filter container to be placed stably in the placement chamber and on the weighing equipment, and also simplifies the shape of the filter container.

[0013] Furthermore, the bottom height of the filter container is designed to be flush with the bottom height of the placement cavity. A connecting protrusion is provided on the lower part of the side wall of the filter container, and a recess is formed between the connecting protrusion and the bottom of the filter container. The filter container abuts against the supporting protrusion through the recess.

[0014] Furthermore, the weighing equipment includes a lifting mechanism and a weighing instrument. The lifting height of the weighing equipment is equal to the height of the supporting protrusion. This design ensures that the filter container, after being lifted, does not contact the turntable, thereby avoiding inaccurate measurements.

[0015] Furthermore, the sprinkler equipment includes a sprinkler head, a water supply pipe, and a switch valve. The sprinkler head is connected to an external water supply device through the water supply pipe, and the switch valve is located on the water supply pipe.

[0016] Furthermore, the spraying equipment includes a connecting cover, the opening diameter of which is larger than the opening diameter of the filter container. When the spraying equipment sprays onto the filter container, the connecting cover abuts against the opening of the filter container.

[0017] Furthermore, the filtration equipment includes a water receiving tank, which is located below the conveying mechanism, and the water receiving tank is equipped with a clearance section in conjunction with the water filling station. Attached Figure Description

Detailed Implementation

[0032] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "horizontal", "inner", and "outer" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0033] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0034] See Figures 1 to 12This embodiment discloses an automatic and precise liquid addition washing system 2 for use on a detector 1. The detector 1 includes a body 10 with a water addition station. The washing system 2 includes a filtration device 5, a weighing device 3, and a spraying device 4 on the body 10. The filtration device 5 includes a conveying mechanism 51 and a filter container 52. The filter container 52 is mounted on the conveying mechanism 51 and is conveyed by the conveying mechanism 51 to enter or leave the water addition station. The spraying device 4 and the weighing device 3 are mounted on the water addition station. The weighing device 3 weighs the filter container 52 and generates a sensing signal. The spraying device 4 starts spraying into or stops spraying into the filter chamber of the filter container 52 according to the sensing signal.

[0035] See Figure 1-5 As shown, to avoid interference between the spraying device 4 and the weighing device 3, the spraying device 4 is located above the water filling station, and the weighing device 3 is located below the water filling station, with their positions opposite each other. When the filter container 52 is conveyed to the water filling station, it is located between the two. The weighing device 3 includes a lifting mechanism and a weighing instrument 33. The weighing instrument 33 is mounted on the lifting mechanism so that it can rise or reset under the drive of the lifting mechanism, so that the filter container 52 is lifted by the weighing instrument 33 and weighed. Through the cooperative use of the lifting bracket 31 and the weighing instrument 33, it can be ensured that the filter container 52 is stably supported and lifted during the weighing process, thereby improving the accuracy and stability of the weighing.

[0036] Referring to Figures 1 and 3-6, the specific design of the aforementioned conveying mechanism 51 is as follows: it includes a turntable 511 and a rotary drive mechanism 512. The output end of the rotary drive mechanism 512 is connected to the middle of the turntable 511, causing the turntable 511 to rotate under the drive of the rotary drive mechanism 512. The turntable 511 is provided with at least one placement cavity 514, which extends longitudinally through the turntable 511, and its bottom inner circumference is provided with a support protrusion 513 for supporting the filter container 52. In this way, the turntable 511 is provided with several placement cavities 514 for placing the filter container 52, thereby forming several filtration stations. Furthermore, by rotating the turntable 511, several filter containers 52 can be queued for water filling. After each filter container 52 has finished filling with water, it can wait outside the water filling station for the next water filling. The water filling and waiting time can be adjusted by rotating the turntable 511 according to the testing needs, thus realizing efficient and flexible filter container 52 conveying and water filling operations.

[0037] To make the connection between the weighing instrument 33 and the filter container 52 more stable, the weighing device 3 includes a lifting bracket 34, which is located at the upper end of the weighing instrument 33. The upper end of the lifting bracket 34 is provided with a lifting part 341, and the bottom of the filter container 52 is provided with a connecting groove 521 that matches the lifting part 341. The weighing instrument 33 abuts against the filter container 52 through the lifting part 341 of the lifting bracket 34.

[0038] The specific structural scheme of the aforementioned lifting mechanism is as follows: it includes a lifting bracket 31 and a lifting drive mechanism 32. The lifting bracket 31 includes a support base 311, a lifting guide rod 312, and a connecting seat 313. Two lifting guide rods 312 are provided and are longitudinally arranged on the support base 311. The connecting seat 313 has a sleeve hole, and the connecting seat 313 is movably sleeved on the lifting guide rod 312 through the sleeve hole, so that it can be raised or lowered relative to the support base 311 or reset under the drive of the lifting drive mechanism 32. The aforementioned lifting drive mechanism 32 is a lifting drive motor, and its output end is provided with a connecting block 321. One side of the connecting block 321 has an arc-shaped protruding wedge shape, and the connecting part abuts against the lower surface of the connecting seat 313. The lifting drive motor drives the connecting block 321 to rotate, thereby causing the connecting seat 313 to slide relative to the surface of the connecting block 321, thereby driving it to rise or fall.

[0039] As shown in 7-8, in order to make the filter container 52 simple in structure and able to be placed stably on the placement cavity 514 and the weighing device 3, the overall exterior of the filter container 52 is cylindrical.

[0040] The bottom height of the filter container 52 is designed to be flush with the bottom height of the placement cavity 514. A connecting protrusion 522 is provided on the lower part of the side wall of the filter container 52. A recess is formed between the connecting protrusion 522 and the bottom of the filter container 52. The filter container 52 abuts against the supporting protrusion 513 through the recess.

[0041] To avoid the turntable 511 affecting the measurement accuracy, the lifting height of the weighing device 3 is equal to the height of the supporting protrusion 513, so that after the filter container 52 is lifted, it is no longer in contact with the turntable 511.

[0042] The specific structural scheme of the above-mentioned spraying equipment 4 is as follows: it includes a spray head (not shown in the figure), a water supply pipe 42, a switch valve (not shown in the figure) and a water tank 44. The spray head is connected to the water tank 44 through the water supply pipe 42. The switch valve is located on the water supply pipe 42. A connecting cover 43 is provided at the spray head, and the distance between the connecting cover 43 and the filter container 52 is equal to the lifting height of the weighing equipment 3. After the filter container 52 is lifted, the connecting cover 43 covers the opening of the filter container 52 to isolate the filter container 52 from the outside world and prevent water from splashing outward.

[0043] The connecting cover 43 is generally conical. The upper part of the outer side wall of the filter container 52 is provided with a connecting boss 523 to match the connecting cover 43. The upper surface of the connecting boss 523 is an inclined surface that matches the connecting cover 43.

[0044] The aforementioned filtration device 5 includes a water receiving tank 53, which is located below the conveying mechanism 51. The water receiving tank 53 is equipped with a clearance section 531 in conjunction with the water filling station.

[0045] Referring to Figures 9-11, the main body 10 of the detector includes a base 11 and a housing. The housing is mounted on the base 11, and a water tank 53 is mounted on the base 11. A through hole is provided in the middle of the base 11. A turntable 511 is located on the upper side of the base 11, and a rotary drive mechanism 512 is located on the lower side of the base 11. The output end of the rotary drive mechanism 512 passes through the through hole and connects to the middle of the turntable 511. The spraying device 4 and the weighing device 3 are respectively located above and below the base 11.

[0046] The aforementioned water receiving trough 53 is formed on the machine base 11, and a water-blocking protrusion (not shown in the figure) is provided on the outer periphery of the through hole.

[0047] Workflow: The conveyor starts, driving the turntable 511 to rotate axially, conveying the filter container 52 to be filled with water to the water filling station and keeping it stopped. The weighing device 3 starts, lifting the filter container 52 and weighing it. The spraying device 4 sprays water onto the filter container 52. Spraying stops when the weight data sent by the weighing device 3 matches the preset data. The weighing device 3 lowers to reset the filter container 52. The turntable 511 rotates to convey the filter container 52 to the outside of the water filling station and conveys the next filter container 52 to be filled with water to the water filling station. The filter container 52 that has been filled with water undergoes the subsequent filtration process outside the water filling station and waits for the next water filling operation.

[0048] The washing system 2 of this invention transports the filter container 52 to the water filling station via a conveying mechanism 51. A weighing device 3 measures the weight of the filter container 52 at the water filling station in real time, generating a sensor signal. The spraying device 4 automatically starts / stops water filling based on the sensor signal. After water filling is completed for one filter container 52, the conveying mechanism 51 can move the filter container 52 away from the water filling station and transport the next filter container 52 to the water filling station. Compared with the prior art, the washing system 2 of this invention, used on the detector 1, can achieve fully automated and precise water filling without manual operation, effectively improving efficiency.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
