Embodiment 1

[0069] see Figure 1-8 , this embodiment provides a special equipment for pulverizing phenolic plastics based on the mechanochemical method. The special equipment is equipment for pulverizing large-sized materials into required sizes. The equipment includes a support frame 25, a primary crushing device, a secondary crushing device, a tertiary crushing device and an automatic adjustment device. These three crushing devices can crush phenolic plastics in turn, and the automatic adjustment device controls the three-stage crushing device to use appropriate mechanical stress to break its cross-linking chemical bonds to reduce its molecular weight, so that it can regain certain plasticity and chemical activity.

[0070] The support frame 25 is used to support the entire device, and it has a motor frame 22 and a mounting frame 27 . The supporting frame 25 can be directly placed on the ground, or can be installed on other equipment platforms. The support frame 25 can be made of mate...

Embodiment 2

[0086] This embodiment provides a method for pulverizing phenolic plastics based on the mechanochemical method, which is applied to the special equipment for pulverizing phenolic plastics based on the mechanochemical method in Example 1, and includes the following steps.

[0087] Detect the stress of the phenolic plastic falling from the crushing gap into the crushing cavity for transverse shearing and longitudinal extrusion. In this embodiment, the stress on the phenolic plastic can be known through a plurality of strain sensors 40 , and these strain sensors 40 are evenly distributed along the tapered outer cutter 38 to monitor the stress on the phenolic plastic in the cavity at all times.

[0088] Determine whether the stress is within a preset interval. The preset interval has a lower limit and an upper limit. This interval can be set according to actual needs, especially according to the situation of phenolic plastics and the appropriate mechanical stress required to break...

Embodiment 3

[0093] This embodiment provides a computer terminal, which includes a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the program, the steps of the method for pulverizing phenolic plastics based on the mechanochemical method in Embodiment 2 are realized.

[0094] When the method of Embodiment 2 is applied, it can be applied in the form of software, such as a program designed to run independently, installed on a computer terminal, and the computer terminal can be a computer, a smart phone, a control system, and other Internet of Things devices. The method in Embodiment 2 can also be designed as an embedded running program, installed on a computer terminal, such as a single-chip microcomputer.

Abstract

The invention discloses special phenolic plastic crushing equipment based on a mechanochemical method and a crushing method. The equipment comprises a supporting frame, a primary crushing device, a secondary crushing device, a third-stage crushing device and an automatic adjusting device, wherein the primary crushing device comprises a crushing box, a first motor, a first transmission rod, a plurality of cutter rests, a plurality of blades, a plurality of fixed cutters, a screen and a guide hopper, the secondary crushing device comprises a first roller, a second roller, a second transmission rod and a bevel gear set, and the third-stage crushing device comprises a second motor, a conical blade group and a plurality of strain sensors, and the conical blade group comprises a conical inner cutter and a conical outer cutter. According to the special phenolic plastic crushing equipment, the material is rapidly crushed, the crushing efficiency and the crushing effect are greatly improved, cross-linked chemical bonds of phenolic plastic can be broken, the molecular weight of the phenolic plastic can be reduced, cross-linked chemical bonds with weak bond energy can be broken without breaking a main chain of a polymer, the phenolic plastic has certain plasticity and chemical activity again, and regeneration of a new mixed material is facilitated.

Description

technical field [0001] The invention relates to a special equipment for plastic pulverization in the technical field of plastic pulverization, in particular to a special equipment for pulverizing phenolic plastics based on the mechanochemical method, and also to a method for pulverizing phenolic plastics based on the mechanochemical method. Background technique [0002] The general concept of a pulverizer is explained as a device that crushes large-sized materials into required sizes. In daily life, it is necessary to process some bulk waste, larger waste or raw materials, which need to be pulverized with a pulverizer to make the pulverized particles Meet the requirements, and its crushing efficiency should be high. [0003] In daily life, the pulverizer only crushes the material into a fine powder. As for some microscopic changes such as the chemical properties and material form of the material, there is no control. For example, phenolic plastics use appropriate mechanical ...
