Description
Technical field
The utility model belongs to field of chemical equipment, relates to a kind of powder roller, is specifically related to a kind ofly can regulate the roller rolling intensity.
Background technology
In the process of laboratory Kaolinite Preparation of Catalyst, often need to roll the intermediate powder of catalyst, because the kind of catalyst is a lot, characteristic also varies, and the pressure of roller is fixing, can not meet the requirement of multiple catalysts.In addition, roller in the past can only rely on estimating one's own ability of muller to roll powder, and the general small volume of the roller in laboratory, the weight of muller is relatively light, does not reach good rolling effect.How to solve use for laboratory roller and can adapt to various materials, and to have good rolling effect be one of major issue faced in catalyst preparation process.
Summary of the invention
The utility model is for the problems referred to above, proposes a kind of powder roller of adjustable rolling pressure.
The technical solution of the utility model: use for laboratory powder roller, comprises work feed bin, hopper, be provided with rolling wheel in work feed bin, rolling wheel connects reductor and switch board, it is characterized in that roller is provided with the regulator for regulating rolling wheel pressure.
Regulator described in the utility model is located at the location mid-shaft of work feed bin, and the top of rolling wheel is provided with spring, and spring housing is in rotating shaft, and upper end is provided with adjusting nut, carry out the flexible of regulating spring, thus it is adjustable to realize rolling pressure by rotating nut.
Usually, described work feed bin, rolling wheel, hopper and regulator are all stainless steel 304 materials.
Described rolling wheel is with fluted.
Described hopper is positioned at work bin bottom.
The utility model is applicable to containing CuO, ZnO, Al
2o
3deng the preparation of the catalyst of metal oxide.
The utility model powder rolls function and regulates according to the characteristic of powder and suitable roll intensity, and reach the requirement of catalyst preparing, regulative mode is simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment roller.
1-reductor, 2-hopper, 3-works feed bin, 4-regulator, 5-rolling wheel, 6-switch board.
Detailed description of the invention
The test of butyraldehyde hydrogenation catalyst is prepared so that the utility model to be described in laboratory below by embodiment roller.
Embodiment:
As shown in Figure 1, roller comprises the present embodiment: 1-reductor, 2-hopper, and 3-works feed bin, 4-regulator, 5-rolling wheel, 6-switch board.
In embodiment, be provided with rolling wheel 5 in work feed bin 3, rolling wheel 5 connects reductor 1 and switch board 6, and its main feature is the regulator 4 that roller is provided with for regulating rolling wheel 5 pressure.
Described regulator 4 is located at the location mid-shaft of work feed bin 3, and the top of rolling wheel 5 is provided with spring, and spring housing is in rotating shaft, and upper end is provided with adjusting nut, carry out the flexible of regulating spring, thus it is adjustable to realize rolling pressure by rotating nut.
Work feed bin 3 in embodiment, rolling wheel 5, hopper 2 and regulator 4 are all stainless steel 304 materials.Rolling wheel 5 is with fluted, hopper 2 is positioned at bottom work feed bin 3.
Application example:
(composition is CuO, ZnO, Al to get the intermediate powder of 600g butyraldehyde hydrogenation catalyst
2o
3, graphite etc.) be equally divided into 3 parts, every part of 200g, bulk density is 0.80 g/ml called after A, B, C respectively.Successively A, B, C powder is poured in roller, rotating nut, regulate rolling pressure, open hopper after respectively rolling 30min, discharging, measure the bulk density rolling rear particle respectively: A-0.98 g/ml, B-1.12 g/ml, C-1.23 g/ml.Carry out compression molding respectively to A, B, C, the finished catalyst of system, measure finished product bulk density, data are in table 1.
Three, table 1 rolls the sample stacking density under condition
As can be seen from Table 1: by adjustment rolling pressure, the build-up of particles density rolled out can be controlled, thus control the bulk density of finished catalyst.
Claims (5)
1. a use for laboratory powder roller, comprises work feed bin, hopper, and be provided with rolling wheel in work feed bin, rolling wheel connects reductor and switch board, it is characterized in that roller is provided with the regulator for regulating rolling wheel pressure.
2. use for laboratory powder roller as claimed in claim 1, it is characterized in that described regulator is located at the location mid-shaft of work feed bin, the top of rolling wheel is provided with spring, and spring housing is in rotating shaft, and upper end is provided with adjusting nut.
