Abstract
The utility model discloses retarding construction in a kind of catalyst rotary kiln, comprise rotary kiln wall and be arranged on the some retardance weir plates on rotary kiln wall inner chamber.Described retardance weir plate is arc surfaced, arrangement straggly between described retardance weir plate.Distance range between the retardance weir plate of described adjacent lines is 10-20cm.The cambered surface direction of described adjacent retardance weir plate is consistent.The utility model utilizes the weir plate of arrangement straggly to realize significantly extending catalyst and in the time of staying effect of rotary kiln, catalyst fully can be contacted with steam, promote the quality of catalyst.
Description
Technical field
The utility model relates to a kind of technical field of preparation of metals catalyst rotary kiln, more particularly, relates to retarding construction in a kind of catalyst rotary kiln.
Background technology
Catalyst enter driven by rotating drum in rotary kiln time, need to input a large amount of steam simultaneously, help catalyst react.In order to obtain the contact effect of better catalyst and steam, can solve from the following aspect: the cavity extending rotary kiln, but so just increase production cost, and need more and that air pressure is stronger steam to enter, so just cause the operating pressure of steam manufacturing cell, and rotary kiln is too short, will cause steam and catalyst exposure insufficient, and to be released from the spinning movement of rotary kiln too quickly.The quality of catalyst will be caused like this to decline.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant, through repeatedly putting into practice improvement, devises retarding construction in a kind of catalyst rotary kiln, can significantly in the time of staying of rotary kiln, fully can contact with steam by extending catalyst.
Technical scheme: in order to realize foregoing invention object, the technical scheme that the utility model adopts is: retarding construction in a kind of catalyst rotary kiln, comprises rotary kiln wall and is arranged on the some retardance weir plates on rotary kiln wall inner chamber.Described retardance weir plate is arc surfaced, arrangement straggly between described retardance weir plate.
Distance range between the retardance weir plate of described adjacent lines is 10-20cm.
The cambered surface direction of described adjacent retardance weir plate is consistent.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
The utility model utilizes the weir plate of arrangement straggly to realize significantly extending catalyst and in the time of staying effect of rotary kiln, catalyst fully can be contacted with steam, promote the quality of catalyst.
Accompanying drawing explanation
Fig. 1 is the structural representation of retarding construction in a kind of catalyst rotary kiln of the utility model.
Fig. 2 is the schematic diagram that retardance weir plate arranges on rotary kiln wall.
Detailed description of the invention
Below by a most preferred embodiment, the technical program is described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, retarding construction in a kind of catalyst rotary kiln, comprise rotary kiln wall 1 and be arranged on the some retardance weir plates 2 on rotary kiln wall 1 inner chamber, described retardance weir plate 2 is arc surfaced, and the cambered surface direction of described adjacent retardance weir plate 2 is consistent.
As shown in Figure 2, arrangement straggly between described retardance weir plate 2 on rotary kiln wall 1.Distance range between the retardance weir plate 2 of described adjacent lines is 10-20cm.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
