Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a raw material grinding and kiln tail oxygen control structure. Background Art

[0002] Vertical mill is mainly used for grinding cement raw materials and cement. Vertical mill is a grinding equipment that integrates fine crushing, drying, grinding, powder selection and conveying. The vertical mill feeding device is a device that feeds the vertical mill.

[0003] Existing vertical mill feeding devices mostly use belt conveyors, which feed smoothly but are expensive.

[0004] In order to save costs, feed pipes are often used to feed materials, and the materials rely on their own gravity to feed the vertical mill through the feed pipe;

[0005] The existing problem is that in order to allow the material to enter the vertical mill more smoothly, the feed pipe must be set at an angle, but the material is easily blocked in the inclined feed pipe.

[0006] To this end, we propose a raw material grinding and kiln tail oxygen control structure to solve the existing problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1

[0028] like Figure 1-Figure 4 As shown, the utility model proposes a raw material grinding and kiln tail oxygen control structure, including an upper tube 1, a lower tube 2, a base 3, a cylinder 8 and a hammer 12. The upper tube 1 is plugged into the lower tube 2, and the upper tube 1 can perform telescopic and sliding movements in the lower tube 2. The outer wall of the upper tube 1 is installed with the cylinder 8, and the hammer 12 is elastically provided in the cylinder 8 through a spring 11.

[0029] Based on Example 1:

[0030] During the use of the raw material grinding and kiln tail oxygen control structure of the utility model, the device can be installed on the feed pipeline of the raw material grinding, and the upper pipe 1 and the lower pipe 2 form a sleeve-movable feed pipeline. The upper pipe 1 of the device and the hose part of the feed pipeline are connected to each other through the flange 6 to ensure that the upper pipe 1 has space to move;

[0031] When a blockage occurs in the pipeline, the upper pipe 1 moves to push out the material blocked on the inner wall of the lower pipe 2. At the same time, the upper pipe 1 uses knocking and vibration to shake the material off, thereby improving the fluidity of the material and preventing the feed pipeline from being blocked.

[0032] Embodiment 2

[0033] like Figure 1-Figure 4 As shown, the raw material grinding and kiln tail oxygen control structure proposed by the utility model, compared with the first embodiment, this embodiment also includes: a rubber ring 10 is installed on the outer wall of the bottom end of the upper tube 1, and the outer wall of the rubber ring 10 contacts the inner wall of the lower tube 2. Through the design of the rubber ring 10, the sealing effect at the connection position of the upper tube 1 and the lower tube 2 can be ensured;

[0034] A flange 6 is installed at the top of the upper tube 1, and mounting holes 7 are equidistantly provided on the flange 6. The device can be installed on the feed pipeline for raw material grinding. The upper tube 1 and the lower tube 2 form a feed pipeline that can be sleeved and moved. The upper tube 1 of the device is connected to the hose part of the feed pipeline through the flange 6, and the lower tube 2 is directly connected. The upper tube 1 can be limited to move without deflection, ensuring that the upper tube 1 has space to move.

[0035] The outer wall of the lower tube 2 is mounted with a base 3 by bolts, and a gear 4 is rotatably mounted on the base 3;

[0036] A rack 5 is installed on the outer wall of the upper tube 1 by bolts, and the rack 5 is in a gear meshing state with the gear 4;

[0037] Through the cooperation of the above structure, when working, the power device drives the gear 4 to rotate, and through the meshing action between the gear 4 and the rack 5, the upper tube 1 is driven to slide inside the lower tube 2.

[0038] The outer wall of the cylinder 8 is installed with an electromagnetic block 9 by bolts, and the outer wall of the hammer head 12 is installed with an iron rod 13 by bolts, and the iron rod 13 and the working surface of the electromagnetic block 9 correspond to each other;

[0039] A hammer head 12 is slidably mounted inside the cylinder 8, and a spring 11 is provided between the hammer head 12 and the inner wall of the cylinder 8;

[0040] Through the cooperation of the above structure, during use, the electromagnetic block 9 is energized to generate magnetism, and under the action of magnetic attraction, the iron rod 13 drives the hammer head 12 away from the outer wall of the upper tube 1, and the spring 11 is deformed at this time. When the electromagnetic block 9 is powered off, under the elastic force of the spring 11, the hammer head 12 hammers the outer wall of the upper tube 1. By controlling the on and off state of the electromagnetic block 9, the hammer head 12 can repeatedly hammer the upper tube 1;

[0041] The original length of the spring 11 is greater than the height of the cylinder 8 . The length of the spring 11 is designed to ensure that the spring 11 has sufficient elastic force to support the hammer head 12 .

[0042] Furthermore, in the process of controlling oxygen at the kiln tail, the feeding mechanism and the feeding pipe are sealed and a sealing ring is used to press the connection. The setting of the sealing ring can seal the connection between the feeding mechanism and the feeding pipe, which can prevent the raw material powder from overflowing from the connection and reduce the oxygen content at the kiln tail;

[0043] In addition, the connection between the feed pipe and the material guide pipe for storing materials and conveying materials in the feeder is sealed, which also increases the sealing of the feeder and realizes the sealing of the vertical mill feed, which can reduce the oxygen content at the kiln tail and save electricity consumption.

[0044] It should be noted that the structure of the electromagnetic block 9 is an existing mature technology, and its working principle and internal structure are known to technicians in the relevant technical field. The utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here, and technicians in this field can make any selection according to their needs or convenience.

[0045] The gear 4 of the present invention also needs to be provided with a power device to enable it to work normally, and as is well known to those skilled in the art, the provision of the power is commonplace, and it all belongs to conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.
