Technical Field

[0001] This utility model belongs to the field of cement grinding aid production technology, specifically relating to an optimization device for the calcination production process of cement grinding aid. Background Technology

[0002] Cement grinding aids are chemical additives added during the cement grinding process. Their main function is to improve the grinding efficiency and performance of cement without impairing its final properties. Grinding aids can improve the fluidity, strength, and durability of cement, and enhance its early and later strength. Using grinding aids can save on clinker usage and increase the amount of industrial waste residue used, thereby reducing cement production costs. Calcination processes are used in the production of cement grinding aids.

[0003] However, in implementing the relevant technology, the following problems were found in the above technical solution: when the cement grinding aid material enters the calcining furnace for calcination, part of the waste heat will be dissipated through the exhaust gas flow, and if this waste heat is not utilized, it will increase energy loss and waste a portion of energy.

[0004] Therefore, an optimized device for the calcination production process of cement grinding aids is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Implementation

[0023] Please see Figure 1 -4, A device for optimizing the calcination production process of cement grinding aid, comprising: a base 1 and an insulation box 2;

[0024] A furnace body 3 is fixedly installed inside the insulation box 2. A waste heat pipe 4 is fixedly installed at one end of the furnace body 3. An insulation layer 5 is fixedly installed inside the furnace body 3.

[0025] A mixing pipe 6 is fixedly installed inside the furnace body 3. A gas pipe 7 is fixedly installed at one end of the mixing pipe 6, and an oxygen pipe 8 is fixedly installed at the other end of the mixing pipe 6. A mixing chamber 9 is opened inside the insulation layer 5, and an air outlet 10 is opened inside the insulation layer 5. A support rod 11 is fixedly installed inside the furnace body 3.

[0026] The technical solution provided in this embodiment is as follows: In use, firstly, one end of the rocker arm 18 is pressed down by the handle 19, then the lifting rod 14 is pulled up by the rotating part 16 and the connecting part 15, thereby lifting the door panel 13. Then, the handle 19 is locked at the bottom of the limiting plate 20 to prevent the door panel 13 from falling. Next, the raw materials for the cement grinding aid to be calcined are placed inside the furnace body 3, above the support rod 11. Then, the gas pipe 7 and oxygen pipe 8 deliver oxygen and gas into the mixing pipe 6, allowing for preliminary mixing of the oxygen and gas. Finally, the mixture enters the mixing chamber 9, allowing... Oxygen and fuel gas are thoroughly mixed and then ejected through outlet 10. The mixed gas is then ignited by an ignition rod. The handle 19 is removed, causing the door panel 13 to fall and block the feed inlet of the furnace body 3 through the limiting groove 12. This allows the flame to calcine the raw materials of the cement grinding aid. The exhaust gas after combustion carries residual heat into the interior of the waste heat pipe 4. Then, through the waste heat pipe 4, some of the residual heat is dissipated between the insulation box 2 and the furnace body 3, reducing heat loss from the furnace body 3. The insulation box 2 retains the temperature to prevent heat loss. The remaining exhaust gas is then discharged from one end of the waste heat pipe 4.

[0027] Furthermore, a limiting groove 12 is fixedly installed on one side of the furnace body 3, a door panel 13 is movably installed inside the limiting groove 12, a lifting rod 14 is fixedly installed on one side of the door panel 13, a connecting piece 15 is rotatably installed on the outside of the lifting rod 14, and a rotating piece 16 is rotatably installed inside the connecting piece 15.

[0028] Specifically, by installing a door plate 13 inside the limiting groove 12, the door plate 13 can block the feed inlet of the furnace body 3 when it falls, preventing the flame inside the furnace body 3 from being ejected through the feed hopper, affecting the temperature inside the furnace body 3, and affecting the calcination of the cement grinding aid.

[0029] Furthermore, a limiting shaft 17 is fixedly installed on one side of the limiting groove 12, a rocker arm 18 is rotatably installed on the outside of the limiting shaft 17, a handle 19 is rotatably installed on the inside of the rocker arm 18, and a limiting plate 20 is fixedly installed on one side of the insulation box 2.

[0030] Specifically, by rotating the handle 19 inside the rocker arm 18 and fixing the limiting plate 20 to one side of the heat preservation box 2, when the door panel 13 is lifted by pressing down the rocker arm 18 with the handle 19, the limiting plate 20 can lock the handle 19, thereby keeping the door panel 13 lifted, which makes it convenient to put the raw materials to be calcined into the furnace body 3 for calcination.

[0031] Furthermore, the waste heat pipe 4 is located between the insulation box 2 and the furnace body 3, and the insulation box 2 is made of ceramic fiber.

[0032] Specifically, by placing the waste heat pipe 4 between the insulation box 2 and the furnace body 3, the waste heat inside the waste heat pipe 4 can heat the surface of the furnace body 3, thereby preventing the loss of heat from the surface of the furnace body 3. The insulation box 2, made of ceramic fiber, can keep the furnace body 3 warm.

[0033] Furthermore, the gas pipe 7 and the oxygen pipe 8 are connected to an external gas storage structure, and the ratio of gas to oxygen is pre-mixed.

[0034] Specifically, by connecting the gas pipe 7 and the oxygen pipe 8 to the external gas storage structure, the stability of the flame during calcination can be increased. Furthermore, by pre-mixing the gas and oxygen ratios, the flame temperature can be increased, and combustion can be made more complete, reducing the generation of harmful gases.

[0035] Furthermore, the insulation layer 5 has a thickness of no less than ten centimeters, and there are multiple support rods 11 inside the insulation layer 5.

[0036] Specifically, by fixing multiple support rods 11 inside the insulation layer 5, the multiple support rods 11 can support the raw materials that need to be calcined, so that the bottom of the raw materials can also be calcined by the flame, and the raw materials can be calcined more fully.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
