Description

Technical Field

[0001] The utility model relates to the technical field of mirabilite powder production, in particular to a production device for separating mirabilite powder from mother liquor. Background Technique

[0002] Mirabilite is often used in the treatment of diseases such as excess heat accumulation, abdominal fullness and pain, dry and hard stools, and intestinal abscess swelling. Natural impure mirabilite is dissolved in water, then filtered, and the filtrate (also called "mother liquor") is heated and concentrated, and finally mirabilite crystals can be precipitated after cooling.

[0003] After retrieval, in the application with the patent application number 202122541129.1, a boiling device for mirabilite production is disclosed, including a frame and a boiling pot installed on the top of the frame. The top of the boiling pot is communicated with a feed hopper, and a heating layer and a heat preservation layer are sequentially arranged inside the side wall and the bottom wall of the boiling pot from inside to outside. A spiral air duct is arranged inside the heat preservation layer. The top end of the spiral air duct is communicated with an air inlet pipe, and the bottom end of the spiral air duct is communicated with an air outlet pipe. A driving motor is installed on the top of the boiling pot. The output end of the driving motor is fixedly connected with a stirring shaft. Stirring rods are installed on the part of the stirring shaft penetrating into the boiling pot. The bottom of the boiling pot is communicated with a discharge pipe, and a cooling tank is arranged below the discharge pipe;

[0004] Although the boiling device for mirabilite production can reduce the heat loss of the heating layer by introducing the water vapor inside the boiling pot into the spiral air duct, realize the secondary utilization of heat energy, has the functions of energy conservation and environmental protection, and reduces the production cost of mirabilite, this boiling device for mirabilite production can only obtain a concentrated liquid containing mirabilite and cannot directly separate mirabilite powder from the concentrated liquid.

[0005] Therefore, we propose a production device for separating mirabilite powder from mother liquor. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a production device for separating mirabilite powder from mother liquor, which solves the problem that the existing device can only obtain a concentrated liquid containing mirabilite and cannot directly separate mirabilite powder from the concentrated liquid.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: A production device for separating mirabilite powder from mother liquor includes a boiling pot for heating the mirabilite concentrated liquid. One side of the bottom surface of the boiling pot is fixedly installed with a discharge pipe, a first control valve is installed on the discharge pipe, and a feed hopper is installed on the top surface of the boiling pot;

[0008] A cooling and crystallization assembly is provided at the bottom of the cooking pot. The cooling and crystallization assembly includes a cooling hopper, a discharge pipe, a filter screen, and a second control valve. A stirring assembly is provided in the cooling hopper. A heating wire connected to a power source through a wire is fixedly installed on the inner wall of the discharge pipe. The bottom end of the discharge pipe is fixedly installed on one side of the top surface of the cooling hopper. The cooling hopper is communicated with the discharge pipe. A discharge pipe is fixedly installed in the middle of the bottom surface of the cooling hopper. A filter screen is fixedly sleeved on the inner wall of the discharge pipe. A second control valve located below the filter screen is fixedly installed on the discharge pipe;

[0009] The stirring assembly includes a motor, a shaft rod, stirring rods, and spiral blades. The motor is fixedly installed in the middle of the top surface of the cooling hopper. The output end of the motor penetrates through the top surface of the cooling hopper and is fixedly connected to a shaft rod extending into the interior of the discharge pipe. Spiral blades are fixedly sleeved on the outer surface of one end of the shaft rod located inside the discharge pipe.

[0010] Preferably, evenly distributed stirring rods are fixedly installed on the side wall of one end of the shaft rod located inside the cooling hopper. The end of the stirring rod away from the shaft rod contacts the inner wall of the cooling hopper. Among them, by driving the shaft rod to rotate through the motor, the stirring rods are driven to stir the concentrated liquid or the mirabilite crystals precipitated in the cooling hopper. Stirring the concentrated liquid can accelerate the cooling rate of the concentrated liquid, and stirring the mirabilite crystals can crush them.

[0011] Preferably, the bottom end of the shaft rod is rotatably sleeved on the middle of the top surface of the filter screen through a bearing ring. Among them, the shaft rod can be supported.

[0012] Preferably, the cooling and crystallization assembly further includes a return pipe and a water pump. A return pipe is fixedly installed on the side wall of the discharge pipe between the filter screen and the second control valve. A one-way valve is installed on the return pipe. A water pump is fixedly installed on the top surface of the cooking pot. One end of the return pipe away from the discharge pipe is fixedly connected to the water inlet end of the water pump. The water outlet end of the water pump is communicated with the interior of the cooking pot through a connecting pipe. Among them, after the mirabilite in the concentrated liquid crystallizes, it will be blocked at the top by the filter screen. The liquid at the bottom of the discharge pipe can be transported back to the interior of the cooking pot through the water pump and the return pipe for continuous heating. The remaining mirabilite in the liquid can be continuously heated and crystallized, which is beneficial to reducing the waste of mirabilite. The one-way valve can prevent the gas or liquid in the cooking pot from entering the interior of the discharge pipe through the return pipe.

[0013] Preferably, an annular plate is fixedly installed on the bottom surface of the cooking pot. Three support legs distributed in an annular array are fixedly installed on the bottom surface of the annular plate. The cooling hopper is fixedly welded on the side walls of the three support legs. Among them, the cooking pot and the cooling hopper can be supported conveniently through the annular plate and the support legs.

[0014] The present utility model provides a production device for separating mirabilite powder from mother liquor, which has the following beneficial effects:

[0015] 1. For the production device for separating mirabilite powder from mother liquor, by conveying a part of the concentrated liquid in the boiling pot to the cooling hopper, and driving the shaft rod and the stirring rod and spiral blades on its outer surface by a motor to stir the concentrated liquid, the cooling time of the concentrated liquid is reduced. The mirabilite in a crystalline state will be filtered by the filter screen, and then the liquid passes through the filter screen. By opening the second control valve, the liquid in the discharge pipe can be discharged. The mirabilite crystals are heated by the heating wire to make them in a dry state.
