Description

Technical Field

[0001] This utility model belongs to the field of raw material grinding technology, and in particular to a chemical raw material grinding device. Background Technology

[0002] In chemical production, a variety of chemical raw materials are required, and these raw materials come in various states. Solid raw materials constitute a significant portion of these materials. To facilitate processing, these solid raw materials require pretreatment, with grinding being a common pretreatment step. However, existing chemical grinding methods are relatively inefficient, mostly relying on cutting blades to cut the raw materials. Consequently, the ground materials vary in size, resulting in low grinding efficiency.

[0003] A chemical raw material processing and grinding device, disclosed in CN220310551U, involves pouring chemical raw materials into the device base for stirring and grinding. A telescopic cylinder then moves a push rod up and down, tamping the ground chemical raw materials into a collection trough inside the device base. However, its grinding efficiency remains limited and has room for improvement. Utility Model Content

[0032] A fixed seat 6 is installed at the center of the inner circumference of the grinding box 1. A grinding disc 8 is provided below the fixed seat 6. A cover door 10 is provided on one side of the lower half of the grinding box 1. The cover door 10 is rotatably connected and fixed by a latch.

[0033] Please see Figure 2In order to achieve cooking and pre-grinding, a heating tube 5 is installed inside the heating bucket 4. The heating tube 5 is fixed by a bracket. The heating bucket 4 has a conical structure. The bottom of the heating bucket 4 is provided with a liquid outlet with a valve. One side of the bottom of the heating bucket 4 is connected to a liquid guide pipe 11 for draining liquid. One end of the liquid guide pipe 11 is equipped with a filter screen. The added liquid needs to be selected as a liquid that cannot react with the raw materials.

[0034] Please see Figure 2 and Figure 3 In order to achieve preliminary crushing, a through groove 7 is provided in the center of the fixed base 6. Two crushing toothed rollers 42 are arranged inside the through groove 7. The two crushing toothed rollers 42 are symmetrically distributed and a central rod 41 is arranged in the center. The central rod 41 is rotatably connected to the through groove 7. Two rotary motors 43 are installed on the outside of the grinding box 1. The drive end of the rotary motor 43 is connected to one end of the central rod 41.

[0035] Please see Figure 2 and Figure 3 In order to achieve lifting and rotating grinding, the inner bottom of the fixed base 6 is set as a recessed deep part, and the top of the grinding disc 8 is set as a convex shape and fixed with multiple protruding teeth. The convex shape is adapted to the deep part and all have serrations.

[0036] The grinding disc 8 is equipped with multiple heating elements 9, which can be heating wires, etc. The bottom of the grinding disc 8 is provided with an annular inner groove. Two limiting plates 32 are used to limit the sliding of the inner circumference of the inner groove. A hydraulic rod 31 is connected between the bottom of the limiting plate 32 and the inner bottom of the grinding box 1.

[0037] A fixing sleeve 21 is installed at the center of the bottom of the grinding disc 8. A fixing rod 22 is fixedly engaged on the inner circumference of the fixing sleeve 21. A limiting part is provided at the top of the fixing rod 22. A drive motor 23 is installed at the center of the bottom of the grinding box 1.

[0038] The aforementioned components and electrical equipment are all existing technologies or technologies that can be implemented at present. Their working principles, dimensions and models are not related to the functions of this application, so they will not be described in detail. All of them are controlled by remote control switches.

[0039] Working principle

[0040] When this chemical raw material grinding device is needed, raw materials and liquids are added through the liquid inlet, and the heating tube 5 is activated to heat and cook the inside, softening the raw materials and making them easier to grind.

[0041] Open the valve of the liquid guide pipe 11 to filter out the liquid, then open the bottom valve of the heating hopper 4 to let the raw material fall onto the crushing toothed roller 42, then start the rotary motor 43 to drive the crushing toothed roller 42 to rotate and pre-crush the raw material.

[0042] When the raw material falls to the top of the grinding disc 8, the heating element 9 and the drive motor 23 are activated. When the drive motor 23 is running, it drives the fixed rod 22 to rotate, which causes the fixed sleeve 21 to drive the grinding disc 8 to rotate. At the same time, the hydraulic rod 31 is activated, which causes the grinding disc 8 to reciprocate up and down, thereby realizing the grinding of lifting and rotating.

[0043] During the grinding process, the heating element 9 can achieve a drying effect. Then, the grinding material can be taken out by opening the cover door 10.

[0044] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
