[0036] The rack 10 can be connected by welding process of steel plate or profile steel to form a solid frame structure. Carbon steel or stainless steel material can be used, which has good mechanical properties and corrosion resistance. The rack 10 can also be made of aluminum profile rack 10, which is light, corrosion resistant and easy to assemble, and is convenient for rapid erection and adjustment.

[0037] The crusher 30 is used for physically crushing the 3,5-dichlorobromobenzene after condensation and crystallization. The structure can refer to the impact crusher or hammer crusher. Specifically, in the hammer crusher, the hitting structure on the rotating crushing shaft mainly includes a hammer head. The hammer head is installed on the rotating disc of the main shaft, and rotates at high speed in the crushing cavity 206 to impact and hit the material, so as to realize crushing. The hammer head is usually made of wear-resistant material to withstand long-term wear. In the impact crusher, a rotor is arranged on the rotating shaft, and a certain number of hitting plates (or hammer heads) are fixed on the rotor. The hitting plates are rigidly connected with the rotor and are usually made of wear-resistant high manganese steel or other alloy steel. The rotor rotates under the drive of the motor to impact and hit the material, so as to realize crushing. Preferably, for the material to be crushed according to the scheme, the crusher 30 comprises a hollow stirring shaft 301 and a plurality of radial crushing rod groups 302. The hollow stirring shaft can reduce the self-weight, reduce the required driving force, save energy, and rotate through the radial crushing rod groups to hit and crush the crystals. The plurality of crushing rods of each radial crushing rod group are arranged in a straight line at equal intervals along the axial direction, so that the crystals are continuously hit and crushed in the forward direction. Adjacent two radial crushing rod groups are arranged in a staggered manner in the radial direction, so as to ensure that the crystals can be hit by the radial crushing rod groups at each position. The crusher 30 can crush the 3,5-dichlorobromobenzene to the required particle size.

[0038] The driving mechanism 40 can adopt an electric motor, a hydraulic motor or a pneumatic motor. The electric motor is composed of a power supply, a motor, a transmission device and a controller. The motor, as the core part, converts electrical energy into mechanical energy to drive the equipment to operate. There are many types of motors, and the common ones include DC motors, AC motors and stepping motors, etc. The working principle is that the motor receives the electrical energy provided by the power supply, generates a rotating torque through electromagnetic action, and drives the crusher 30 to rotate and crush the crystal. The advantages of motor drive include good high-speed performance, strong overload resistance, stable low-speed operation, short dynamic response time, low heat and noise. In addition, a hydraulic motor can also be used, which is composed of a hydraulic turbine, a gear transmission and a walking mechanism, etc. The working principle of the hydraulic motor is that the circulating flow of hydraulic oil in the oil cylinder drives the rotation of the hydraulic motor, thereby pushing the crusher 30 to rotate and crush the crystal. The advantages of the hydraulic motor include simple structure, convenient maintenance, smooth running, strong load capacity, and automatic reversing function, which improves the operation efficiency and safety. A pneumatic motor can also be used, which uses compressed air as the working medium and uses the expansion of compressed gas to convert pressure energy into mechanical energy. The working principle of the pneumatic motor is that compressed air passes through the gas distribution valve and is supplied to each cylinder in turn, thereby expanding and doing work, pushing the crankshaft to rotate through the connecting rod, and driving the crusher 30 to rotate and crush the crystal. The advantages of the pneumatic motor include using compressed air as power, safety explosion-proof, no static electricity and sparks; stepless speed regulation, the speed of the motor is adjusted by the pressure and flow of the gas supply; no overload danger, the motor will not be damaged when the load is too large; bidirectional rotation, which can realize forward and reverse rotation function; easy operation, simple maintenance and repair.

[0039] Specifically, the sealing structure includes an O-ring seal, a soft packing seal or a mechanical seal. The O-ring seal is wrapped around the shaft and placed in the shaft hole expansion section, and the outer side of the O-ring is provided with a pressing mechanism. The O-ring is fixed on the tapered surface of the shaft hole expansion section by a pressing nut, forming an annular sealing band, which has good sealing effect. The soft packing seal is filled with soft packing (commonly known as packing) between the shaft and the shell 20, and then pressed tightly with a gland and a screw to achieve the purpose of sealing. The packing material usually includes rubber, leather, polytetrafluoroethylene, etc. The mechanical seal is sealed by relying on the pre-tightening of the elastic element on the dynamic and static ring end face sealing pair and the pressure of the medium and the elastic element.

[0040] The specific structure of the packing machine can include a packaging material supply mechanism, a pressing mechanism, a sealing mechanism, a cutting mechanism and a control mechanism, wherein the packaging material supply mechanism includes a roll paper supply device, a film supply device and the like for providing packaging materials; the pressing mechanism is composed of a pressing device and a pressing plate, during the packing process, the pressing device compresses the articles through the pressing plate to reduce the volume, thereby saving packaging materials and transportation space, the pressing device is usually driven by hydraulic or pneumatic, and the pressing force and time are controlled to realize the packing requirements of different types of articles; the sealing mechanism is composed of a sealing device and a sealing knife, which is used to seal the packaging materials to ensure the sealing of the package, and the sealing knife is used to cut off the excess packaging materials, so that the packed articles are more neat and beautiful; the control mechanism includes a PLC controller, a touch screen and the like, which is used to control the operation of the whole packing machine, during the working process, the packing machine operates according to the following process: starting the packing machine, the condensed and broken 3,5-dichlorobromobenzene crystals are conveyed to the workbench of the packing machine through the discharge port 204, the packaging material supply mechanism provides the packaging materials to wrap around the products, and the sealing mechanism seals the packaging materials to ensure the sealing of the package.
