DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment. Obviously, the described embodiment is part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Please refer to Figures 1 to 4 The utility model provides a kind of technical scheme: a cement chromium reducing agent adding device, including bunker 1, electric flow control valve 2 is installed at the bottom end opening of bunker 1, electric flow control valve 2 bottom end is connected with the discharge pipe 4, bunker 1 includes bin body 101, bin body 101 perimeter outer wall is fixedly connected with several evenly distributed supporting legs 5, bin body 101 inner wall is fixedly installed with screen disc 102.

[0020] Please refer to Figures 2 to 4 Screen disc 102 is inclined, and vibration motor 103 is fixedly installed at one side of the bottom of screen disc 102.

[0021] By inclining screen disc 102, the residence time of chromium reducing agent on screen disc 102 can be improved, so that the chromium reducing agent is fully screened and filtered, and the large pieces of chromium reducing agent that cannot pass through screen disc 102 are guided to gradually move to the lower side of screen disc 102 by the vibration of vibration motor 103, so that the large pieces of chromium reducing agent do not affect the feeding efficiency.

[0022] Further, a crushing mechanism is fixedly installed at the lower side of the top of screen disc 102, and the crushing mechanism includes a housing 104, the housing 104 is fixedly connected with screen disc 102, a crushing roller 107 is rotatably installed in the housing 104, and the crushing roller 107 is connected with a driving device.

[0023] The rotation of the crushing roller 107 driven by the driving device can crush the large pieces of chromium reducing agent by extrusion in cooperation with screen disc 102, so as to improve the feeding efficiency and reduce the waste of materials.

[0024] Further, a sliding groove 105 is formed on each side surface of the housing 104, a sliding block 106 is slidably installed in each sliding groove 105, the crushing roller 107 is rotatably installed between the two sliding blocks 106, a driving motor 108 is fixedly installed on one side surface of one of the sliding blocks 106, one end of the output shaft of the driving motor 108 is fixedly connected with one end of the crushing roller 107, and the other sliding block 106 is connected with an adjusting mechanism.

[0025] The adjusting mechanism can drive the sliding block 106 to slide in the sliding groove 105, so as to adjust the distance between the crushing roller 107 and the screen disc 102. The size of the chromium reduction agent agglomerates or the feeding requirement can be flexibly adjusted, and the limitation in use is reduced.

[0026] Further, the adjusting mechanism includes a connecting lug 109 fixedly installed on the side surface of the corresponding sliding block 106.

[0027] By rotating the adjusting screw 110, the connecting lug 109 can be driven to move up and down, thereby driving the corresponding sliding block 106 to displace in the sliding groove 105, changing the height position of the crushing roller 107 relative to the screen disc 102, changing the crushing degree of the chromium reduction agent agglomerates, and improving the applicable scenarios.

[0028] Further, the rotary unloader 3 is further connected in communication between the electric flow control valve 2 and the feeding pipe 4.

[0029] The rotary unloader 3 further ensures the smoothness of the chromium reduction agent during the adding process, prevents the blockage problem caused by poor feeding, and improves the stability and reliability of the entire adding device.

[0030] Working principle: first, the chromium reduction agent is stored in the silo 1, and its outflow amount is accurately controlled by the electric flow control valve 2 to ensure that it is added to the cement production process as needed. During the outflow process, the chromium reduction agent first passes through the screen disc 102, which is inclined and provided with a vibration motor 103. The vibration effectively screens out impurities and large particles. Subsequently, the chromium reduction agent that has been preliminarily screened enters the crushing mechanism, and the crushing roller 107 driven by the driving motor 108 further refines the treatment, improving the uniformity and dispersity of the chromium reduction agent particles. Finally, the chromium reduction agent that has been finely treated smoothly enters the feeding pipe 4 through the rotary unloader 3 and is finally added to the cement.

[0031] It should be noted that the specific model specifications of the vibration motor 103, the driving motor 108, the electric flow control valve 2, and the rotary unloader 3 need to be determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the art, and therefore will not be described in detail.

[0033] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
