Description

Technical Field

[0001] The utility model relates to the technical field of brine filtering, in particular to a mineral brine filtering device. Background Art

[0002] In the processing of salt lake brine minerals, saturated magnesium chloride brine is an important raw material. The production process has high requirements on the turbidity of magnesium chloride brine. Unfiltered magnesium chloride brine often contains more impurities such as mud and sand and cannot be directly used in the production process. To ensure that the turbidity of magnesium chloride brine meets the requirements of the production process, a filtering device is required to effectively filter the magnesium chloride brine. In the process of primary filtration of mineral brine by existing filtering devices, the filtering mechanism will be blocked after long-term use. To ensure normal processing and filtration of the brine, when the filtering mechanism is seriously blocked, it is necessary to stop the machine to clean the filtered waste residue. Since the filtered waste residue cannot be discharged during the filtration of the brine, continuous filtration processing of the brine cannot be achieved during the filtration of the brine, thereby reducing the processing efficiency of the brine. Therefore, a mineral brine filtration device is proposed to address the above problems. Utility Model Content

[0018] Example 1

[0019] like Figure 1-2 As shown, a mineral brine filtering device comprises a fixed box 1, a controller 2 is fixedly connected to the front end of the fixed box 1, a motor 3 is fixedly connected to the bottom end of the fixed box 1, a spiral blade 4 is fixedly connected to the end of the main shaft of the motor 3, a fixed sleeve 5 penetrating the fixed box 1 is rotatably connected to the outer side of the spiral blade 4, and the fixed sleeve 5 is fixedly connected to the fixed box 1, a sewage pipe 6 is connected to the left end of the fixed sleeve 5, a filter screen 7 is provided on the outer side of the main shaft of the motor 3, a liquid inlet pipe 8 penetrating the fixed box 1 is fixedly connected to the right side of the top end of the fixed box 1, a liquid outlet pipe 9 is connected to the right end of the fixed box 1, a brine pump 11 is fixedly connected to the left end of the fixed box 1, a delivery pipe 12 penetrating the fixed box 1 is connected to the top end of the brine pump 11, and the delivery pipe 12 is fixedly connected to the fixed box 1, and the outer right end of the delivery pipe 12 is connected to uniformly distributed nozzles 13.

[0020] Example 2

[0021] like Figure 2 As shown, in order to solve the problem of poor filtering effect of the filter screen 7 on brine, the main shaft of the motor 3 is fixedly connected to the filter screen 7, and the filter screen 7 is rotatably connected to the fixed sleeve 5 and the fixed box 1. By fixing the filter screen 7 on the outside of the main shaft of the motor 3 and rotatably connected to the fixed sleeve 5 and the fixed box 1, when the motor 3 drives the filter screen 7 to rotate, the filtering effect of the brine is better.

[0022] Example 3

[0023] like Figure 1-2As shown, in order to solve the problem that it is inconvenient to discharge the residual brine inside the device after the device is finished using, the bottom end of the outer side of the liquid outlet pipe 9 is connected with a discharge pipe 10, and the other end of the discharge pipe 10 is connected with the fixed box 1, and the inner side of the discharge pipe 10 is fixedly connected with an electric control valve. When the device is finished using, by opening the electric control valve in the discharge pipe 10, it is convenient to discharge the residual brine inside the device through the discharge pipe 10 and the liquid outlet pipe 9.

[0024] Example 4

[0025] like Figure 1-2 As shown, in order to solve the problem that the brine cannot be prevented from crystallizing and condensing on the outside of the filter screen 7 when the brine temperature is low, the bottom end of the brine pump 11 is connected to a fixed box 14 fixedly connected to the fixed box 1, and the inner side of the fixed box 14 is fixedly connected to an electric heating pipe 15 through a connecting rod. The bottom end of the fixed box 14 is connected to a fixed pipe 16, and the other end of the fixed pipe 16 is connected to the fixed box 1. When the brine pump 11 is started to extract brine and spray it back to the filter screen 7 through the delivery pipe 12 and the nozzle 13, the extracted filtered brine is heated by the electric heating pipe 15, which can prevent the brine from crystallizing and condensing on the outside of the filter screen 7 when the temperature is low.

[0026] Example 5

[0027] like Figure 2 As shown, in order to solve the problem of inconvenience in monitoring the temperature of the brine discharged into the device, the bottom end of the liquid inlet pipe 8 is connected to a bracket 17, and the bracket 17 is fixedly connected to the fixed box 1, and the inner side of the bracket 17 is fixedly connected to a temperature sensor 18 through a connecting rod. By arranging the temperature sensor 18 at the bottom of the liquid inlet pipe 8, it is convenient to monitor the temperature of the brine discharged into the device.

[0028] In this embodiment, when the impurities such as mud and sand in the mineral brine are initially filtered, the sensing range of the temperature sensor 18 is set by the controller 2, and then the device is started by the controller 2. At this time, the motor 3 will drive the filter screen 7 to rotate, and the brine pump 11 will be started. Then, the brine is pumped into the device through the liquid inlet pipe 8. When the brine is discharged into the device through the liquid inlet pipe 8, the brine will first be detected by the temperature sensor 18, and then filtered by the filter screen 7. The filtered mud and sand and other impurities will accumulate at the bottom of the inner side of the filter screen 7. In the process of the brine passing through the temperature sensor 18 for temperature detection, when the detected temperature is within the set temperature range, the brine pump 11 will draw the filtered brine into the fixed box 14 through the fixed pipe 16, and then spray it back to the filter screen 7 through the delivery pipe 12 and the nozzle 13, thereby realizing the back-spraying and anti-blocking treatment of the filter screen 7. Then, the excess brine filtered out will be discharged through the liquid outlet pipe 9. Because the liquid inlet of the liquid outlet pipe 9 is higher than the liquid inlet of the fixed pipe 16, the bottom of the inner side of the fixed box 1 There will always be filtered brine for the brine pump 11 to extract. In the process of filtering the brine through the rotating filter screen 7, because the motor 3 will also drive the spiral blade 4 to rotate, the rotating spiral blade 4 cooperates with the fixed sleeve 5 to transport the impurities such as mud and sand filtered by the filter screen 7, and the filtered waste residue can be discharged through the sewage pipe 6. When the filtering of the brine is completed, the electric control valve in the discharge pipe 10 is opened by the controller 2, and the brine at the bottom of the inner side of the fixed box 1 can be completely discharged. In the process of discharging brine into the device through the liquid inlet pipe 8 for filtration, when the temperature sensor 18 detects that the temperature of the brine discharged is lower than the set range, the controller 2 will turn on the electric heating pipe 15. At this time, the brine pump 11 will pump the filtered brine into the fixed box 14 through the fixed pipe 16 for heating through the electric heating pipe 15, and then spray it back to the rotating filter screen 7 through the delivery pipe 12 and the nozzle 13, which can prevent the brine from crystallizing and condensing on the outside of the filter screen 7 due to its low temperature, thereby ensuring the normal filtration of the brine by the filter screen 7.
