[0002] In the operation of traditional salt-making evaporation tanks, the measurement of the solid-liquid ratio is a crucial link, which is related to the product quality and production efficiency. However, for a long time, this measurement process mainly relies on manual operation. Workers usually need to use a graduated measuring cup to sample the liquid in the tank and calculate the solid-liquid ratio through a series of complex steps.
[0003] This method not only has a cumbersome operation process, consuming time and effort, but also due to the instability and subjectivity of manual operation, the measurement results often have large deviations. Such deviations may lead to inaccurate control in the production process, thereby affecting the quality of the final product.
[0004] In addition, the manual measurement method also has the problem of low efficiency and cannot meet the requirements of modern and high-efficiency production. Especially in the salt-making industry, the frequent sampling and measurement work bring a huge labor load to workers, which not only affects the production efficiency but also increases the labor cost. Summary of the Utility Model

Cleaning pipes are installed on both the upper and lower sides of the solid-liquid separation disc. A sensor is installed on the solid quantity detection and sensing support near the discharge opening of the sampling pipe. A number of small holes are arranged on the surface of the solid-liquid separation disc.
[0007] Preferably, a baffle is fixedly installed on the solid quantity detection and sensing support near the upper side of the solid-liquid separation disc.
[0008] Preferably, a sampling valve is installed on the sampling pipe.
[0009] Preferably, a spray head is installed at the end of the cleaning pipe close to the solid-liquid separation disc, and the other end of the cleaning pipe away from the solid-liquid separation disc is externally connected to a water pipe.
[0010] Preferably, a movable baffle is installed inside the material retaining plate on the solid quantity detection and sensing bracket, and the movable baffle is hinged to the solid quantity detection and sensing bracket.
[0011] Preferably, the outer end of the solid quantity detection and sensing bracket is fixed on the ground or the wall.
[0012] Preferably, the sensor is a material quantity detection sensor.
[0013] Preferably, one end of the material retaining plate is open and the other end is closed, and the side wall is of an arc structure.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] In the automatic sampling device in the salt-making evaporation tank, through the automated and mechanized design, the measurement process of the solid-liquid ratio in the salt-making evaporation tank is significantly simplified, and the measurement accuracy and efficiency are improved.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] The present invention provides an automatic sampling device in a salt-making evaporation tank, as Figures 1 - 3 shown, which includes a solid-liquid separation disk 2. A solid quantity detection sensing bracket 3 is arranged on the solid-liquid separation disk 2. A transmission shaft 5 is installed in the middle of the solid-liquid separation disk 2. The top end of the transmission shaft 5 is driven to rotate by a motor 6. A sampling pipe 1 is arranged above the solid-liquid separation disk 2 for putting liquid materials onto the solid-liquid separation disk 2. Cleaning pipes 7 are installed on both the upper and lower sides of the solid-liquid separation disk 2 for cleaning operations. A sensor 4 is installed on the solid quantity detection sensing bracket 3 near the discharge port of the sampling pipe 1. A plurality of small holes are arranged on the surface of the solid-liquid separation disk 2 to facilitate the leakage of liquid and realize solid-liquid separation.
[0023] In this embodiment, a baffle plate 8 is fixedly installed on the solid quantity detection sensing bracket 3 near the upper side of the solid-liquid separation disk 2 for blocking materials.
[0024] Specifically, a sampling valve 11 is installed on the sampling pipe 1 for controlling the opening and closing of sampling.
[0025] Further, a spray head 71 is installed at the end of the cleaning pipe 7 close to the solid-liquid separation disk 2. One end of the cleaning pipe 7 far from the solid-liquid separation disk 2 is externally connected to a water pipe to facilitate external cleaning water for cleaning.
[0026] Further, a movable baffle 31 is installed on the inner side of the solid quantity detection sensing bracket 3 where it is located at the baffle plate 8. The movable baffle 31 is hinged to the solid quantity detection sensing bracket 3 to facilitate the rotation of the solid-liquid separation disk 2 without being blocked.
[0027] Further, the outer end of the solid quantity detection sensing bracket 3 is fixed on the ground or wall to facilitate the installation and fixation of the sensor 4.
[0028] Further, the sensor 4 is a material quantity detection sensor for detecting the solid material quantity.
[0029] Further, one end of the baffle plate 8 is open and the other end is closed, and the side wall is of an arc structure to facilitate blocking the solid materials and preventing them from slipping.
[0030] When the automatic sampling device in the salt-making evaporation tank of the utility model is in use, first, the motor 6 drives the transmission shaft 5 to rotate, and then drives the solid-liquid separation disk 2 to rotate. When sampling is required, the sampling pipe 1 is connected to the circulation pipe of the evaporator, and the sampling valve 11 on the sampling pipe 1 is opened, and the liquid material then flows into the rotating solid-liquid separation disk 2 through the sampling pipe 1.
[0031] During the rotation of the solid-liquid separation disk 2, due to the small holes provided on its surface, the liquid part will leak down through the small holes, while the solid part remains on the disk surface, thus realizing solid-liquid separation. At this time, the sensor 4 installed on the solid quantity detection sensing bracket 3 will detect the quantity of the solid material, and send the signal to the main control room DCS for display and application through the sensor 4.
[0032] When the sampling is completed, the sampling valve 11 can be closed to stop sampling. Subsequently, water is supplied through the water pipe externally connected to the cleaning pipe 7, and the spray head 71 is opened to clean the solid-liquid separation disk 2 to ensure the accuracy of the next sampling.
[0033] During this process, the baffle plate 8 plays a role in blocking the sliding of the solid material, ensuring that the solid material can accurately accumulate below the sensor 4. The design of the movable baffle plate 31 ensures that it will not be blocked during the rotation of the solid-liquid separation disk 2, and can also be flipped when needed to facilitate the discharge of the solid material and the cleaning of the device.
[0034] The entire working process has a high degree of automation, is simple and convenient to operate, greatly improves the efficiency and accuracy of sampling, and reduces the complexity and labor intensity of manual operation.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art of this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the utility model, and are not used to limit the utility model.
