Description

Technical Field

[0001] The utility model relates to the technical field of magnesium carbonate production, in particular to a synthetic magnesium carbonate dehydration and drying machine. Background Art

[0002] Magnesium carbonate is an inorganic compound with the appearance of white granular powder. In the process of magnesium carbonate production, the main method of pyrolysis of magnesium bicarbonate solution is to produce magnesium carbonate. After the pyrolysis of magnesium bicarbonate solution is completed, filter pressing is required to obtain the product. Dehydration devices are now mostly used to complete the dehydration of magnesium bicarbonate solution. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a magnesium carbonate filter press device with a publication number of CN208115251U, which includes a device body, a rotating track, a movable shaft, a rotating rod, a first connecting shaft, a telescopic rod, a connecting rod, a rotating shaft, a linkage rod, a rotating shaft, a movable rod, a connecting rod, a push rod, a push plate, a filter press plate, a filter cloth, a rubber diaphragm plate, a filter plate, a concave block, a fixed block, a fixing device, a fixing clamp, a mounting plate, a placement block, an elastic rod, a spring, a support rod and a locking rod. When the magnesium carbonate solution needs to be filtered, the magnesium bicarbonate solution is first introduced from the liquid inlet pipe into the gap between the push plate and the filter press plate in the device body, and then the liquid inlet pipe is closed. Under the action of external force, the rotating rod is rotated around the rotating track under the action of the movable shaft. Then the connecting rod and the movable rod will continuously move, thereby driving the push plate to continuously move downward under the action of the push rod, and then the magnesium bicarbonate solution will be pushed through the filter press plate to filter out the magnesium carbonate. The magnesium bicarbonate solution can filter out the magnesium carbonate under the action of the three layers of filter cloth, rubber diaphragm plate and filter plate. When the filter press plate needs to be replaced after the filtration is completed, the locking rod can be taken out from the fixing clamp, and then the fixing block can be rotated to separate the elastic rod from the filter press plate, and the filter press plate can be pulled out from the groove in the concave block, and the objects on the filter press plate can be replaced. Because the elastic rod and spring inside the fixing clamp protect the filter press plate when the filter press plate is under pressure, it will not be damaged due to excessive external force.

[0004] In the above utility model, the magnesium carbonate solution needs to be moved between the push plate and the filter press plate for filter pressing and dehydration. Part of the water will be adsorbed on the surface of the filter press plate, and manual operation is required to separate the adsorbed water. This increases the number of operating steps and reduces the dehydration efficiency. At the same time, when replacing the filter press plate, the dehydration work needs to be stopped, which reduces the practicality of use.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0015] Furthermore, a first sealing door is installed on the end surface of the shell through a hinge, and a second sealing door is installed on the outer wall of the centrifugal cylinder through a hinge.

[0016] Furthermore, four groups of support columns are installed at the lower part of the shell.

[0017] Furthermore, a drain pipe penetrates the rear end surface of the shell, and a control valve is provided on the side wall of the drain pipe.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model provides a synthetic magnesium carbonate dehydration dryer, which has the following beneficial effects:

[0020] (1) The utility model adopts a centrifugal drum. When the synthetic magnesium carbonate dehydration dryer is actually used, the first sealing door and the second sealing door can be rotated to put the magnesium bicarbonate solution into the centrifugal drum, and then the first sealing door and the second sealing door can be reset. The control panel is used to make the driving motor and the servo motor work. The output end of the servo motor can drive the rotating disk to rotate. The rotating rotating disk can intermittently push the installation sleeve up and down through the first connecting shaft, the second connecting shaft and the connecting plate. The installation sleeve drives the pressure plate to move up and down intermittently through the installation shaft. The pressure plate and the support table can filter the magnesium bicarbonate solution. The water can pass through multiple groups of filters. The hole is moved out of the interior of the centrifugal cylinder, and the water is discharged through the filter cartridge. The output end of the driving motor can drive the centrifugal cylinder to rotate, and the rotating centrifugal cylinder can drive the filter cartridge to rotate. The water on the surface of the filter cartridge is affected by the centrifugal force and will escape and enter the interior of the shell. The control valve is opened and closed, and the water inside the shell can be discharged through the drain pipe. Since the mounting sleeve is connected to the mounting shaft through a bearing, the mounting sleeve will not rotate with the mounting shaft. The two sets of vertical rods and the socket plate can ensure the stability of the up and down movement of the pressure plate. The centrifugal cylinder is set up, and the magnesium carbonate solution can be pressed and centrifugally dehydrated, thereby improving the dehydration efficiency of the synthetic magnesium carbonate dehydration dryer.

[0021] (2) The utility model adopts a filter cartridge. When it is necessary to adjust the use position of the filter cartridge, the control panel is used to shorten the electric push rod, and the lifting plate can move the connecting ring downward through two sets of resistance rods. The connecting ring can move the filter cartridge downward through two sets of mounting rods. During this process, the centrifugal cylinder and the connecting ring will squeeze the two sets of telescopic rods and the two sets of telescopic springs. When the connecting ring rotates with the centrifugal cylinder through the two sets of telescopic rods, the two sets of ball bearings are subjected to friction and roll inside the two sets of ball sockets respectively. Since the surfaces of the two sets of ball bearings are smooth, the two sets of resistance rods can avoid hindering the rotation of the connecting ring. By setting the filter cartridge, when the use position of the filter plate is changed, there is no need to stop the dehydration work, thereby improving the practicality of the synthetic magnesium carbonate dehydration dryer.
