Description

Technical Field

[0001] This utility model relates to the field of salt testing technology, and in particular to a special salt testing device. Background Technology

[0002] The purity, component content, and impurity levels of specialty salts (such as iodized edible salt, low-sodium salt, and industrial specialty salt) are directly related to food safety, industrial production quality, and human health. Therefore, they need to be accurately tested using professional testing equipment.

[0003] In existing technologies, the sieve structure used for filtering salt samples is too simple and lacks a scientifically sound anti-clogging design. In actual operation, the salt sample inevitably contains tiny impurity particles or agglomerated salt particles due to changes in environmental humidity. These substances easily adhere to and accumulate on the sieve surface. As the filtration process continues, these deposits gradually accumulate, eventually causing complete blockage of the sieve pores. This blockage not only interrupts the normal inspection workflow, forcing operators to frequently stop the machine, disassemble the equipment, and manually clean it, but also requires readjusting the equipment after each cleaning, seriously affecting the continuity and stability of the inspection work. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that the screen is prone to clogging and requires frequent cleaning of the screen plate, which affects the inspection efficiency, and to propose a special salt inspection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a special salt testing device, comprising a fixing frame, a filter cylinder, a mixing chamber, and a testing instrument.

[0006] A connecting plate is fixedly connected to the outer surface of the fixed frame. A connecting groove is provided on the top of the connecting plate. The inner wall of the connecting groove is fixedly connected to the outer wall of the filter cylinder. An anti-clogging mechanism is provided on the outer surface of the filter cylinder. A screen is snapped into the inner wall of the filter cylinder. A base plate is fixedly connected to the bottom end of the fixed frame. A support frame is fixedly connected to the top of the base plate. A circular groove is fixedly connected to the top of the support frame. The mixing chamber is rotatably connected to the inner wall of the circular groove. An inspection instrument is fixedly connected to the top of the base plate. The inspection instrument is located directly below the mixing chamber. A rotating mechanism is provided on the outer surface of the support frame.

[0007] Furthermore, the anti-clogging mechanism includes a first motor fixedly installed on the outer wall of the filter cylinder, a rotating rod fixedly connected to the output end of the first motor, a side of the rotating rod away from the first motor being rotatably connected to the inner wall of the filter cylinder, and centrifugal circles fixedly connected to both ends of the outer surface of the rotating rod. The anti-clogging mechanism is located below the screen.

[0008] Furthermore, the inner wall of the filter cylinder is provided with a sliding groove, which is slidably engaged with the screen. Springs are fixedly connected to both ends of the top of the screen, and the top of the springs is fixedly connected to the inner wall of the sliding groove.

[0009] Furthermore, a discharge pipe is connected through the bottom of the filter cartridge, and a valve is provided on the outer surface of the discharge pipe.

[0010] Furthermore, the rotating mechanism includes a second motor fixedly installed at the bottom of the support frame, the output end of the second motor is fixedly connected to a drive gear, the outer surface of the drive gear is meshed with a gear ring, and the gear ring is fixedly connected to the outer wall of the mixing chamber.

[0011] Furthermore, a dropper is connected through the bottom of the mixing chamber, and a control valve is provided on the outer surface of the dropper.

[0012] Furthermore, a fixed suction cup is fixedly connected to the bottom of the base plate, and the fixed suction cup is distributed in a rectangular shape at the bottom of the base plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the problem of screen clogging is solved by setting an anti-clogging mechanism and a screen. When the first motor starts, its output end drives the rotating rod and the centrifugal circles at both ends to rotate inside the filter cylinder. The centrifugal force generated by the rotation of the centrifugal circles can push the salt sample on the screen to quickly pass through the screen. At the same time, the screen slides and engages with the inner wall of the filter cylinder through a sliding groove, and the top is connected to the inner wall of the sliding groove through a spring. Under the action of centrifugal force, the screen will vibrate slightly up and down along the sliding groove. The vibration can shake off the fine impurities attached to the surface of the screen, avoiding the accumulation of impurities and clogging of the screen holes. There is no need to frequently stop the machine to clean the screen, which effectively ensures the continuous operation of the inspection process and significantly improves the inspection efficiency.

[0014] 2. In this utility model, the mixing chamber is rotated as a whole by a rotating mechanism, and the stability of the equipment is enhanced by a fixed suction cup, taking into account both the uniformity of mixing and the safety of operation. On the one hand, the second motor drives the active gear to rotate, and the active gear meshes with the gear ring on the outer wall of the mixing chamber, driving the mixing chamber to rotate stably along the circular groove at the top of the support frame, ensuring uniform salt solution concentration, providing accurate test samples for the testing instrument, and improving the detection accuracy.

[0017] Please see Figures 1-5 This utility model provides a technical solution: a special salt testing device, including a fixed frame 1, a filter cylinder 2, a mixing chamber 3 and a testing instrument 4.

[0018] The following section will explain the specific setup and function of the filter cartridge 2 and the mixing chamber 3.

[0019] In this embodiment: a connecting plate 11 is fixedly connected to the outer surface of the fixing frame 1, a connecting groove 12 is provided on the top of the connecting plate 11, the inner wall of the connecting groove 12 is fixedly connected to the outer wall of the filter cylinder 2, an anti-clogging mechanism 5 is provided on the outer surface of the filter cylinder 2, a screen 8 is snapped into the inner wall of the filter cylinder 2, a base plate 13 is fixedly connected to the bottom end of the fixing frame 1, a support frame 6 is fixedly connected to the top of the base plate 13, a circular groove 61 is fixedly connected to the top of the support frame 6, the mixing chamber 3 is rotatably connected to the inner wall of the circular groove 61, an inspection instrument 4 is fixedly connected to the top of the base plate 13, the inspection instrument 4 is located directly below the mixing chamber 3, and a rotating mechanism 7 is provided on the outer surface of the support frame 6.

[0020] The effects achieved by the above components are as follows: the fixing frame 1 provides stable support for the filter cylinder 2 through the connecting groove 12 of the connecting plate 11, ensuring that the filter cylinder 2 remains vertical during the inspection process and preventing salt samples from spilling; the base plate 13 provides an installation foundation for the support frame 6 and the testing instrument 4, realizing the integrated assembly of various components of the equipment; the rotating connection design between the mixing chamber 3 and the circular groove 61 provides structural support for the rotational mixing of the mixing chamber 3, while ensuring the sealing of the mixing chamber 3; the testing instrument 4 is located directly below the mixing chamber 3, which can accurately receive the mixed salt solution sample, providing convenience for subsequent testing. The overall structure realizes a streamlined layout of "filtration-mixing-testing", improving testing efficiency.

[0021] Specifically, the anti-clogging mechanism 5 includes a first motor 51 fixedly installed on the outer wall of the filter cylinder 2. A rotating rod 52 is fixedly connected to the output end of the first motor 51. The end of the rotating rod 52 away from the first motor 51 is rotatably connected to the inner wall of one side of the filter cylinder 2. Centrifugal circles 53 are fixedly connected to both ends of the outer surface of the rotating rod 52. The anti-clogging mechanism 5 is located below the screen 8.

[0022] The effects achieved by the above components are as follows: the first motor 51 serves as a power source, which can drive the rotating rod 52 and the centrifugal circle 53 to rotate stably inside the filter cylinder 2; when the centrifugal circle 53 rotates, it generates centrifugal force, which creates an upward thrust on the bottom of the screen 8. On the one hand, it pushes the salt sample on the screen 8 through the screen holes quickly, reducing the residence time of salt particles on the surface of the screen 8. On the other hand, in conjunction with the vibration structure of the screen 8, it breaks up the phenomenon of salt particles clumping, avoids the clumped salt particles from clogging the screen holes, and solves the problem of screen 8 clogging from the root, eliminating the need for frequent manual cleaning.

[0023] Specifically, the inner wall of the filter cylinder 2 is provided with a sliding groove 21, which is slidably engaged with the screen 8. Springs 81 are fixedly connected to both ends of the top of the screen 8, and the top of the springs 81 is fixedly connected to the inner wall of the sliding groove 21.

[0024] The effects achieved by the above components are as follows: the slide groove 21 provides a sliding track for the screen 8, ensuring that the screen 8 can only move in the vertical direction, avoiding screen 8 deviation and uneven filtration; the spring 81 has an elastic reset function. When the centrifugal force generated by the rotation of the centrifugal circle 53 pushes the screen 8 upward, the spring 81 is compressed. When the centrifugal force weakens, the spring 81 resets, driving the screen 8 to reset downward, forming the up and down vibration of the screen 8. The vibration can shake off the fine impurities attached to the surface of the screen 8, further enhancing the anti-clogging effect. At the same time, the buffering effect of the spring 81 can reduce the collision and wear between the screen 8 and the inner wall of the filter cylinder 2, extending the service life of the screen 8.

[0025] Specifically, a discharge pipe 22 is connected through the bottom of the filter cartridge 2, and a valve is provided on the outer surface of the discharge pipe 22.

[0026] The effects achieved by the above components are as follows: the discharge pipe 22 is the channel for the filtered salt sample to enter the mixing chamber 3, and the valve can precisely control the timing and amount of salt sample discharge; after the salt sample in the filter cylinder 2 has been filtered, opening the valve allows the salt sample to flow into the mixing chamber 3 at a uniform speed along the discharge pipe 22, avoiding a large amount of salt sample rushing in at once and causing uneven mixing; closing the valve can prevent unfiltered salt sample from entering the mixing chamber 3 when filtration is not completed or the equipment is paused, ensuring filtration quality and improving the controllability of the inspection process.

[0027] Specifically, the rotating mechanism 7 includes a second motor 71 fixedly installed at the bottom of the support frame 6. The output end of the second motor 71 is fixedly connected to a drive gear 72. A gear ring 73 meshes with the outer surface of the drive gear 72. The gear ring 73 is fixedly connected to the outer wall of the mixing chamber 3.

[0028] The effects achieved by the above components are as follows: the second motor 71 drives the drive gear 72 to rotate, and through gear meshing transmission, drives the gear ring 73 and the mixing chamber 3 to rotate synchronously; the gear transmission has the characteristics of stable transmission and controllable speed, and the rotation speed of the mixing chamber 3 can be adjusted according to the inspection requirements to ensure that the salt sample and the test reagent are in full contact; improve the mixing uniformity, provide the test instrument 4 with accurate test samples, and reduce the detection error.

[0029] Specifically, a dropper 31 is connected through the bottom of the mixing chamber 3, and a control valve is provided on the outer surface of the dropper 31.

[0030] The effects achieved by the above components are as follows: the dropper 31 adopts a narrow diameter design, which can realize the micro-volume and precise dripping of salt solution, which meets the precise requirements of the test instrument 4 for the amount of test samples and avoids sample waste; the control valve can flexibly adjust the dripping speed and dripping volume. After the salt solution in the mixing chamber 3 is mixed, the control valve can be opened to allow the salt solution to drip slowly into the detection area of ​​the test instrument 4 along the dropper 31, preventing the salt solution from flowing in quickly and causing the detection area to overflow, and ensuring that the testing process is carried out in an orderly manner.

[0031] Specifically, a fixed suction cup 14 is fixedly connected to the bottom of the base plate 13, and the fixed suction cup 14 is distributed in a rectangular shape at the bottom of the base plate 13.

[0032] The effects achieved by the above components are as follows: the fixed suction cup 14 squeezes out the internal air and uses atmospheric pressure to tightly adhere to the operating table. The rectangular distribution can make the equipment evenly stressed and enhance the overall stability. When the first motor 51 and the second motor 71 vibrate during operation, the fixed suction cup 14 can counteract the displacement trend caused by the vibration and ensure the stability of the inspection process.

[0033] Working principle: When using this special salt testing equipment, first pour the special salt sample to be tested into the filter cylinder 2, start the first motor 51, the first motor 51 drives the rotating rod 52 and the centrifugal circle 53 to rotate, the centrifugal force generated by the centrifugal circle 53 pushes the screen 8 to vibrate up and down along the slide groove 21, the salt sample quickly passes through the screen 8 under the action of centrifugal force and vibration, and impurities are trapped above the screen 8, thus achieving the filtration of the salt sample.

[0034] After filtration, open the valve of the discharge pipe 22, and the filtered salt sample flows into the mixing chamber 3 along the discharge pipe 22. Add an appropriate amount of test reagent into the mixing chamber 3, and start the second motor 71. The second motor 71 drives the mixing chamber 3 to rotate along the circular groove 61 through the meshing of the drive gear 72 and the gear ring 73, so that the salt sample and the test reagent are fully mixed. After mixing, open the control valve of the dropper 31, and the mixed salt solution is accurately dripped into the test instrument 4 below along the dropper 31. The test instrument 4 detects the purity, component content and other indicators of the salt solution, completing the special salt inspection process. Throughout the process, the fixed suction cup 14 at the bottom of the base plate 13 always adheres to the operating table, ensuring stable operation of the equipment and eliminating the need for frequent shutdowns to clean the screen 8, thus improving inspection efficiency and detection accuracy.
