Description

Technical Field

[0001] The utility model relates to the technical field of turbidity material pretreatment, in particular to a POSM device outlet turbidity analyzer pretreatment system. Background Art

[0002] The turbidity analyzer is a very precise turbidity measuring instrument. It is based on the principle that an 880nm infrared light source passes through an optical lens and penetrates the sample liquid, and measures scattered light in a 90° direction according to the ISO7072 standard. This turbidity analyzer can be used on filtration devices in different places to measure the turbidity of raw water or purified water, such as drinking water, various production and industrial water, and any place where qualified water is required.

[0003] During the measurement process of the turbidity analyzer, when bubbles, particulate impurities, etc. exist in the liquid, they will cause great interference to the measurement, especially when detecting and analyzing substances in industrial water, the substances in the industrial water are prone to foam during the flow process. At the same time, because when detecting industrial water, there are toxic substances such as ethylbenzene, phenylethanol, acetophenone, benzyl alcohol, etc. in the industrial water samples, the pipelines in the turbidity analyzer are all closed, but the closed pipelines will increase the difficulty of bubble elimination, impurity treatment and other technologies. In order to facilitate the elimination of bubbles, the utility model provides a POSM device outlet turbidity analyzer pretreatment system. Utility Model Content

[0004] The purpose of the utility model is to provide a POSM device outlet turbidity analyzer pretreatment system in view of the defects of the prior art, so as to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a POSM device outlet turbidity analyzer pretreatment system, which includes a sample tube, a control valve is installed in the middle of the sample tube, a defoaming device is arranged on one side of the sample tube, the sample tube and the defoaming device are connected through a root ball valve, a ball valve and a solenoid valve, a sampler is connected to the defoaming device, the sampler is connected to the turbidity analyzer, a pump is connected to the sampler, one end of the pump is connected to the discharge port of the flushing liquid through the solenoid valve, the defoaming device includes a defoaming barrel, and the defoaming A top cover is installed on the top of the barrel, a defoaming mechanism is arranged on the lower side of the top cover, and a driving motor is installed on the upper side of the top cover, and the driving motor is used to drive the defoaming mechanism to perform intermittent bidirectional rotation. When the defoaming mechanism rotates clockwise, the liquid inside the defoaming barrel is stirred, and the foam is guided upward during the stirring process, and the foam is broken in the process of guiding upward. When the liquid in the defoaming barrel rotates clockwise, the defoaming mechanism rotates counterclockwise, and at this time the defoaming mechanism guides the foam downward so that the foam is pressed into the liquid.

[0006] As a further improvement of the technical solution, an electromagnetic valve is arranged between the defoaming device and the electromagnetic valve close to the sample tube, and the solenoid valve is connected to the ball valve and the liquid inlet in sequence. At the same time, a ball valve is connected to the defoaming device, and the other end of the ball valve is connected between the pump and the sampler. Desalted water adds liquid to the defoaming device through the liquid inlet.

[0007] As a further improvement of the technical solution, the other end of the sample tube is connected with a root valve and a solenoid valve in sequence, and the other end of the solenoid valve is installed between the pump and the solenoid valve close to the discharge port.

[0008] As a further improvement of the present technical solution, the bottom of the defoaming barrel is a downwardly protruding conical structure, and a receiving tube is installed in the middle position of the bottom of the defoaming barrel. When the defoaming mechanism rotates, it drives the liquid in the defoaming barrel to rotate, and impurities in the liquid enter the receiving tube with the help of the force of the liquid rotation.

[0009] As a further improvement of the technical solution, the defoaming mechanism includes a rotating disk, which is arranged in the middle position of the lower side of the top cover, and the rotating shaft of the driving motor passes through the side wall of the top cover and is rotatably connected to the rotating disk.

[0010] As a further improvement of the present technical solution, a plurality of guide plates are arranged in a circular array on the side wall of the rotating disk. The guide plates are arranged at an angle and have a plurality of holes. When the defoaming mechanism rotates clockwise, the guide plates guide the liquid and foam upward. When the defoaming mechanism rotates counterclockwise, the guide plates guide the liquid and foam downward.

[0011] As a further improvement of the technical solution, a pressure plate is fixed on the upper end of the guide plate away from the rotating disk. The pressure plate and the guide plate are inclined in the same direction. When the guide plate guides the liquid and foam to move upward, the pressure plate blocks the liquid and foam.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Liquid is injected into the defoaming equipment through the liquid inlet, and the liquid is driven to circulate in the system by a pump, so that the liquid backwashes the system and flushes away the industrial water to prevent the industrial water from corroding the inside of the device. At the same time, by washing away the industrial water, the device can detect other industrial waters later, thereby improving the accuracy of the device's detection.

[0014] When the defoaming mechanism is rotated, the liquid and foam are first guided upward to remove the foam, and then the defoaming mechanism is rotated in the opposite direction to guide the liquid downward to mix the foam and liquid together, thereby ensuring that the liquid and foam can be fully mixed, thereby improving the accuracy of the device in detecting turbidity.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] like Figure 1-4 As shown, the device includes a sample tube, a control valve is installed in the middle of the sample tube, a defoaming device is arranged on one side of the sample tube, the sample tube and the defoaming device are connected through a root ball valve, a ball valve and a solenoid valve, the defoaming device is connected to a sampler, the sampler is connected to a turbidity analyzer, a pump is connected to the sampler, one end of the pump is connected to a discharge port of a flushing liquid through a solenoid valve, and a solenoid valve is arranged between the defoaming device and the solenoid valve close to the sample tube, a ball valve and a liquid inlet are connected to the solenoid valve in sequence, and a ball valve is connected to the defoaming device, the other end of the ball valve is connected between the pump and the sampler, desalted water adds liquid to the defoaming device through the liquid inlet, the other end of the sample tube is connected to a root valve and a solenoid valve in sequence, and the other end of the solenoid valve is installed between the pump and the solenoid valve close to the discharge port.

[0023] When testing the sample, the industrial water sample is placed in the sample tube, and the industrial water is brought into the defoaming equipment by the pump. The defoaming equipment treats the industrial water to remove particulate impurities and bubbles in the industrial water. After the industrial water treatment is completed, the turbidity analyzer takes out the tested liquid through the sampler. After the industrial water testing is completed, the control valve on the sample tube and the solenoid valve and root valve near the other end of the sample tube are opened, and the ball valve and solenoid valve near the liquid inlet are opened at the same time. Desalted water is added to the system through the liquid inlet, and the pump drives the desalted water to pass through the defoaming equipment, the sampler, and the control valve on the sample tube. The sampler, pump, sample tube, and then the liquid returns to the defoaming equipment. The cycle is repeated to flush the industrial water in the pipeline to ensure that no industrial water remains in the defoaming equipment. When the pipeline is flushed, the solenoid valve near the other end of the sample tube is closed, and the solenoid valve near the flushing liquid discharge port is opened. The pump drives the liquid to leave the device through the flushing liquid discharge port. In this way, the liquid backwashes the system to flush the industrial water to prevent the industrial water from corroding the inside of the device. At the same time, by flushing the industrial water, the device can detect other industrial waters later, thereby improving the accuracy of the device detection.

[0024] In order to facilitate the control of the solenoid valve and turbidity analyzer in the system, a detection controller is set up, which is used to control the opening and closing of the solenoid valve and the detection of industrial water by the turbidity analyzer.

[0025] At the same time, considering that the defoaming equipment not only removes particulate impurities, but also needs to remove foam in industrial water, this case refines the structure of the defoaming equipment, please refer to Figure 2-Figure 4 As shown:

[0026] The defoaming device comprises a defoaming barrel 1, which is a hollow structure. A top cover 2 is installed on the top of the defoaming barrel 1, and the top cover 2 covers the top of the defoaming barrel 1. At the same time, a defoaming mechanism 5 is arranged on the lower side of the top cover 2, and a driving motor 4 is installed on the upper side of the top cover 2. The liquid in the defoaming barrel 1 immerses the lower half of the defoaming mechanism 5. The driving motor 4 is used to drive the defoaming mechanism 5 to perform intermittent bidirectional rotation. When the defoaming mechanism 5 rotates clockwise, the liquid inside the defoaming barrel 1 is stirred, and the foam is guided upward in the process of stirring, and the foam is broken in the process of guiding upward, so as to reduce the content of the foam in the defoaming barrel 1, and the liquid is stirred and rotated in the defoaming barrel 1, and the bottom of the defoaming barrel 1 is arranged It is arranged to be a cone-shaped structure protruding downward, and a receiving tube 3 is installed in the middle position of the bottom of the defoaming barrel 1. When the defoaming mechanism 5 rotates, it drives the liquid in the defoaming barrel 1 to rotate, and the impurities in the liquid are gathered to the middle by the force of the liquid rotation, so that the impurities enter the receiving tube 3 with the help of the force of the liquid rotation, and the impurities entering the receiving tube 3 are collected by the receiving tube 3, so as to reduce the content of impurities in the liquid. When the liquid in the defoaming barrel 1 rotates clockwise, the defoaming mechanism 5 rotates counterclockwise. At this time, the defoaming mechanism 5 guides the foam downward, so that the foam is pressed into the liquid, and the foam and the liquid are mixed together, ensuring that the liquid and the foam can be fully mixed, thereby improving the accuracy of the device in detecting turbidity.

[0027] The structure of the defoaming mechanism 5 is detailed below. The defoaming mechanism 5 includes a rotating disk 51, which is arranged in the middle position of the lower side of the top cover 2, and the rotating shaft of the driving motor 4 passes through the side wall of the top cover 2 and is rotatably connected to the rotating disk 51. The driving motor drives the rotating disk 51 to rotate inside the defoaming barrel 1. At the same time, a plurality of guide plates 52 are arranged in a circular array on the side wall of the rotating disk 51. One point of the guide plate 52 is clamped on the rotating disk 51, and a pressure ring 54 is sleeved on the upper side of the rotating disk 51. The pressure ring 54 is screwed to the rotating disk 51, and one end of the guide plate 52 is fixed by the pressure ring 54 so that the guide plate 52 is fixed on the rotating disk 51. At the same time, the guide plate 52 is tilted, and a plurality of holes are opened on the guide plate 52. When the defoaming mechanism 5 rotates clockwise, the guide plate 52 guides the liquid and foam upward, and part of the liquid guided upward flows into the liquid again through the holes on the guide plate 52. During this process, part of the foam in the liquid is broken, and part of the liquid moves upward along the guide plate 52. At this time, a pressing plate 53 is fixed to the end of the upper side of the guide plate 52 away from the rotating disk 51. The pressing plate 53 and the guide plate 52 are inclined in the same direction. When the guide plate 52 guides the liquid and foam to move upward, the pressing plate 53 blocks the liquid and foam, and the upwardly moving liquid is blocked by the pressing plate 53. With the help of the force of the pressing plate 53 blocking the liquid, the liquid and the foam collide with each other, and the foam and the liquid are mixed together. At the same time, the guide plate 52 drives the liquid inside the defoaming barrel 1 to rotate when it rotates. When the liquid rotates in the defoaming barrel 1, when the defoaming mechanism 5 rotates counterclockwise, the guide plate 52 guides the liquid and foam downward, presses the foam into the liquid, so that the foam is directly mixed with the liquid after breaking, and the substance in the foam is mixed with the liquid, ensuring that the liquid and the foam can be fully mixed, thereby improving the accuracy of the device in detecting turbidity.
