Description

Technical Field

[0001] The utility model relates to the technical field of rough emulsifiers, in particular to a rough emulsifier for emulsion explosive with a filtering structure. Background Technique

[0002] In the patent document CN202022313718.X, "a rough emulsifier for emulsion explosive production with a filtering and impurity removal function" is disclosed, which includes a housing, a feed inlet, a discharge pipe and a motor. The top of the housing is provided with a feed inlet, the bottom end of the housing is fixedly provided with a discharge pipe, and the inner surface of the top end of the housing is fixedly provided with an inner pipe. The top surface of the housing is fixedly provided with a motor, and the output end of the motor is provided with a fixed column, and the fixed column penetrates through the top surface of the housing. For this rough emulsifier for emulsion explosive production with a filtering and impurity removal function, when the material enters the inner pipe from the feed inlet, the rotating fixed column drives the first stirring paddle of the threaded column, and through the spiral action, the oil phase and the water phase are guided to the filter plate for filtration. Since the fixed column drives the first bevel gear to engage with the second bevel gear, the second bevel gear drives the second stirring paddle on the transmission shaft to discharge the impurities through the impeller spiral feeding.

[0003] Although a certain impurity filtering function can be achieved in this patent, the single - filtering method allows some smaller impurities to pass through the filter holes smoothly, resulting in poor filtering performance. And during the filtering process, some impurities with sizes similar to the filter holes are also likely to cause blockage, and the blockage cannot be cleared, affecting the filtering effect. Therefore, we propose a rough emulsifier for emulsion explosive with a filtering structure to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rough emulsifier for emulsion explosive with a filtering structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a rough emulsifier for emulsion explosive with a filtering structure, including an outer housing and an inner housing. The number of the inner housings is two and they are symmetrically installed on the left and right sides of the inner wall of the outer housing. The top of the outer housing is fixedly installed with a feeding cylinder. The bottoms of the left and right sides of the feeding cylinder are respectively communicated with the two inner housings through feeding pipes. The top of the inner housing is fixedly installed with a stirring motor. The output shaft of the stirring motor penetrates into the inner housing. The surface of the output shaft of the stirring motor located inside the inner housing is fixedly connected with a plurality of stirring blades. A plurality of first permeable holes are opened at the bottom of the opposite sides of the two inner housings. The bottom of the outer housing is fixedly connected with a discharge pipe communicated with it;

[0006] A clog - clearing mechanism for dredging the first permeable holes is fixedly installed on the inner wall of the outer housing.

[0007] Further, the blockage clearing mechanism includes fixed blocks fixedly installed on the front and rear sides of the inner wall of the outer casing. A transmission cavity is formed inside the fixed blocks. Two screw rods are rotatably connected to the fixed blocks through limit rotating blocks. One end of each screw rod penetrates into the transmission cavity and is fixedly connected with a driven bevel gear. A translation plate is threadedly connected along the axial direction to the surface of the screw rod located outside the fixed block. Guide rods are symmetrically installed on both sides of the fixed blocks. The translation plate is slidably connected along the axial direction to the surface of the guide rods. First blockage clearing rods are fixedly connected to the positions corresponding to the first material seepage holes on the opposite sides of the two translation plates. A stepper motor is fixedly installed on the top of the fixed block. The output shaft of the stepper motor penetrates into the transmission cavity and is fixedly connected with a driving bevel gear adapted to the driven bevel gear.

[0008] Further, a filter cover is fixedly connected to the inner wall of the outer casing at the position corresponding to the lower part of the first material seepage hole. A plurality of second material seepage holes are formed on the filter cover.

[0009] Further, the bottom of the fixed block is fixedly connected with a lifting plate through a cylinder. Second blockage clearing rods are fixedly connected to the positions corresponding to the second material seepage holes at the bottom of the lifting plate.

[0010] Further, a sewage discharge pipe communicating with the inner casing is fixedly connected to the bottom of the inner casing. A valve is installed on the sewage discharge pipe and one end thereof penetrates to the outside of the outer casing.

[0011] Further, a switch door is hinged to the front of the outer casing at the position corresponding to the filter cover.

[0013] The present utility model can add materials through a feeding cylinder and uniformly introduce the materials into two inner casings through two material passing pipes. After starting the stirring motor, the materials are stirred and emulsified by stirring blades. The first material seepage holes can achieve preliminary impurity filtration. After the materials penetrate, they fall into the filter cover and are secondarily filtered through the second material seepage holes. When the first material seepage holes are blocked, the stepper motor is started, and its output shaft drives the driving bevel gear to rotate. The driven bevel gear engaged therewith drives the screw rod to rotate under the connection of the limit rotating block. The translation plate threadedly connected thereto translates outward under the limit guidance of the guide rod, and the first blockage clearing rod is used to clear the blockage.
