Embodiment 1

[0044] Such as figure 1 As shown, a sealed crushing and screening machine, the sealing crushing and screening integrated machine of the present invention is mainly composed of an automatic feeder 1 capable of continuous feeding, a mechanical crushing part 2, a vibrating screen part 3, a frame body 5, casters 7, etc. . The automatic feeder 1 of the crushing and screening machine communicates with the crushing part 2 through a connecting pipe 38, the discharge end of the crushing part 2 communicates with the vibrating screen part 3 through a soft connection 39, and the crushing part 2 and the vibrating screen part 3 are fixed on the frame body 5 on. The crushing part 2 and the vibrating screen part 3 of the present invention are fixed on the frame body 5, and other structures can also be fixed on the frame body 5, and the frame body 5 can also be set as a split frame body, which is convenient for disassembly and use, or disassembly and transportation . Caster wheels 7 are arr...

Embodiment 2

[0063] On the basis of Example 1, the automatic crushing and screening integrated machine of the present invention is also equipped with a cleaning and drying system 4, which can realize the cleaning function of the crushing part 2, and the automatic feeder 1 of the crushing and screening machine communicates with the cleaning and drying system 4 Then it is connected with the feeding end of the pulverizing part 2, and now the connecting pipe 38 is a straight pipe 38-1 integrally provided with the structure of an inclined pipe 38-2 with an upwardly inclined angle α of 30-45°, and the straight pipe 38 The upper end of -1 is connected to the injector main body 9, the lower end of the straight pipe 38-1 is connected to the crushing part 2, and the inclined pipe 38-2 is connected to the cleaning and drying system 4.

[0064] Such as figure 1 and 10 As shown, the cleaning and drying system 4 includes an atomizing nozzle, a drying fan 4-4, a drying heater 4-3, and an air valve 4-2, ...

Abstract

The invention relates to a sealed crushing and screening machine which is characterized in that an automatic feeder of the crushing and screening machine is communicated with a feeding end of a crushing part, a discharging end of the crushing part is communicated with a vibrating and screening part through flexible connection, and the crushing part and the vibrating and screening part are fixed on a frame body. The problems that an existing smashing and screening machine cannot achieve continuous filling, and air cannot be effectively isolated in the smashing, screening and sample loading processes, so that a sample detection result is inaccurate, and errors are large are solved.

Description

technical field [0001] The invention relates to the technical field of screening machines, in particular to a sealed crushing and screening machine. Background technique [0002] For a long time, many samples used in the analysis of physical and chemical properties in the laboratory are block solids with different sizes. In most cases, the samples need to be in the form of powders with different particle sizes when analyzing physical and chemical properties. Therefore, the laboratory receives After the sample to be analyzed, the sample needs to be pulverized first, and separated into powders of different particle sizes by a sieving mechanism, which is convenient for the analysis and use of different analytical instruments. In the crushing and sieving process, the previous machines were not integrated, nor could they isolate oxygen or specific harmful gases throughout the process, so the crushing and sieving needs to be carried out on two machines, and between the two machine...
