Description

Technical Field

[0001] The invention relates to the field of cement gypsum preparation, and specifically relates to a method and a device for preparing titanium-doped gypsum cement. Background Art

[0002] In the traditional cement industry, there are problems of overcapacity and high emissions. With the call for energy conservation and emission reduction, comprehensive resource utilization and development of green building materials, the comprehensive utilization of titanium gypsum can avoid the damage to the environment caused by gypsum mining in the cement production process. In addition, the price of titanium gypsum is relatively low, which can also reduce corporate costs, meet the development requirements of modern construction, promote the diversified development of building materials, and generate huge economic benefits while having significant environmental significance.

[0003] In the existing cement production process, natural gypsum is required as raw material, and the mining of natural gypsum will cause damage to the environment. At the same time, a large amount of titanium gypsum cannot be effectively utilized, resulting in a waste of resources. The long-term storage of titanium gypsum will also cause damage to the local environment. Therefore, it is necessary to study the production process of titanium-doped gypsum cement to solve these problems. Titanium gypsum replaces natural gypsum to produce cement, which can effectively reduce the amount of natural gypsum used, reduce the damage to the environment caused by the mining of natural gypsum, achieve green production, and save costs for enterprises. In the preparation process of titanium gypsum cement, each raw material needs to be ground and then mixed. When making raw materials, each raw material needs to be proportioned. The traditional proportioning method is weighing, and each raw material is weighed in a certain proportion. The weighing process is time-consuming and labor-intensive. Therefore, it is necessary to set up a preparation method and device for titanium-doped gypsum cement to automatically proportion the raw materials more accurately, reduce manual proportioning time, shorten the preparation period, and increase labor productivity. Summary of the Invention

[0004] The present invention aims to provide a method and apparatus for preparing titanium-doped gypsum cement, which can automatically and accurately proportion raw materials, reduce manual batching time, shorten preparation period, and increase labor productivity.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is as follows: a preparation device for titanium-doped gypsum cement, comprising a preparation barrel, a first bracket fixedly connected to the outside of the preparation barrel, an upper batching barrel, a middle crushing device and a lower stirring device inside the preparation barrel, the batching barrel comprising several storage bins and a first driving device, the storage bins are all connected to a first discharge port arranged on the bottom wall of the preparation barrel, and an opening and closing device is provided at the first discharge port, a second bracket is installed under the batching barrel, the second bracket is fixedly connected to the preparation barrel, a placement rack for placing the batching barrel is fixedly connected in the middle of the second bracket, a central shaft is fixedly connected in the middle of the batching plate, the top end of the central shaft is rotationally connected to the driving device through a bevel gear, and the bottom end of the central shaft is rotationally matched with the placement rack.

[0006] The principle and beneficial effects of the basic solution: During operation, different raw materials are placed in different storage bins, and the first driving device is used to drive the central axis to rotate so that the batching barrel rotates. When the batching barrel rotates, the first discharge port is opened due to the centrifugal force. Due to the different centrifugal forces of the opening and closing device, the opening and closing sizes of the first discharge port are different, thereby automatically adjusting the flow rate of the raw materials in the temporary storage bin, making the raw materials more accurately proportioned, reducing manual batching time, shortening the preparation period, and increasing labor productivity.

[0007] Furthermore, a material receiving trough is provided at the bottom of the batching barrel, the material receiving trough is fixedly connected to the preparation barrel, the upper diameter of the material receiving trough is larger than the lower diameter, and a second discharge port is provided in the middle of the material receiving trough.

[0008] Beneficial effect: the raw materials are discharged from the first discharge port. Since the discharge port rotates with the batching barrel, the dropped raw materials are preliminarily mixed in the receiving trough, and the raw materials in the receiving trough are discharged from the second discharge port.

[0009] Furthermore, the crushing device includes two relatively rotating crushing cylinders, with a first rotating shaft and a second rotating shaft respectively provided in the middle of the crushing cylinders, and blocks are provided on both sides of the axial direction of the crushing cylinders, and the blocks are fixedly connected to the preparation barrel. A first motor is installed in the block on one side, and the output shaft of the first motor is coaxially fixedly connected to a main gear, the main gear is coaxially fixedly connected to the first rotating shaft, the main gear is meshed with a slave gear, and the slave gear is coaxially fixedly connected to the second rotating shaft, the first rotating shaft and the second rotating shaft are both rotatably matched with the block at one end away from the motor, and the second outlet is located above between the two crushing cylinders.

[0010] Beneficial effect: The second output port inputs the raw materials into the middle of the two grinding cylinders, the output shaft of the first motor drives the main gear to rotate, and the two grinding cylinders rotate relative to each other, squeezing the raw materials and grinding them.

[0011] Furthermore, an arched sieve plate is provided below the crushing device, and the lower part of the sieve plate is fixedly connected to the preparation barrel. The crushed raw materials fall into the arched part of the sieve plate and are then sieved out from the sieve holes of the sieve plate. The raw materials that cannot be sieved out roll to the lower part of the sieve plate. A pipe connected to the preparation barrel is provided at the lower part of the sieve plate, and a sand suction pump is connected to the material receiving trough at the other end of the pipe away from the end of the pipe.

[0012] Beneficial effects: The crushed raw materials fall into the middle of the sieve plate, and the suitable raw materials are output through the sieve holes. Since the sieve plate is arched, the incompletely crushed raw materials roll to the lower part of the sieve plate and will be sucked out by the sand suction pump. The sand suction pump will send the incompletely crushed raw materials into the receiving trough and then fall into the crushing device, and the incompletely crushed raw materials will be crushed again until the raw materials are completely crushed.

[0013] Furthermore, the stirring device includes a second driving device and a stirring shaft, a stirring blade is fixedly connected to the stirring shaft, the second driving device drives the stirring shaft to rotate, the second driving device includes an air motor, and an outlet connected to the outside is provided at the bottom of the stirring device.

[0014] Beneficial effect: After being completely crushed, the raw materials fall into the stirring device, and the pneumatic motor is used to drive the stirring shaft to rotate, and the stirring shaft drives the stirring blades to rotate to pneumatically stir the raw materials in the stirring device.

[0015] Furthermore, the opening and closing device includes a slide groove and a slider. The slide groove is located in the bottom wall of the ingredient barrel on the side of the first discharge port close to the preparation barrel wall. The slider is slidably connected to the slide groove. The slider is fixedly connected to the side of the slider close to the preparation barrel. The spring spring coefficients of different first discharge ports are different. The other end of the spring is fixedly connected to the side of the slide groove close to the preparation barrel.

[0016] Beneficial effect: when the batching barrel rotates, the slider slides away from the central axis and slides into the slide groove, thereby opening the first discharge port. Since the spring coefficients of different storage bins are different, under the same centrifugal force, the sliding distances of the slider are different, and the opening degrees of the first discharge port are different. The larger the opening of the storage bin, the faster the raw materials are output and the more raw materials are output. On the contrary, the smaller the opening of the storage bin, the fuller the raw materials are output and the less raw materials are output. Therefore, the spring coefficient is used to adjust the discharge volume of the first discharge port, and the raw materials are automatically proportioned more accurately, which reduces the time of manual batching, shortens the preparation period, and increases labor productivity.

[0017] Furthermore, a method for preparing titanium-doped gypsum cement is characterized by comprising the following preparation steps:

[0018] Step 1: Place clay, iron powder, limestone and grinding aid into different storage bins. The raw materials fall as the batching barrel rotates and mix them preliminarily.

[0019] Step 2: The mixed raw materials are fed into the crushing device, and the crushing cylinder crushes the raw materials.

[0020] Step 3: The crushed raw materials fall onto the sieve plate, which sieves out the suitable raw materials, and the raw materials that are not sieved out are crushed again.

[0021] Step 4: The crushed raw materials fall into the stirring device for pneumatic stirring and then output.

[0022] Step 5: Send the output raw materials into the calcining device for calcination to produce clinker.

[0023] Step 6: Mix and stir the clinker, titanium gypsum, limestone and waste slag.

[0024] Step 7: crushing the mixed clinker, titanium gypsum, limestone and waste residue again.

[0025] Furthermore, the mass parts of clay, iron powder, limestone and grinding aid are respectively: 15 parts of clay, 2 parts of iron powder, 15 parts of limestone and 0.5 parts of grinding aid.

[0026] Furthermore, the mass parts of powder, fly ash and coal-fired slag are respectively: 8 parts of clinker, 4 parts of desulfurized gypsum, 2 parts of titanium gypsum, 4 parts of powder, 4 parts of fly ash and 4 parts of coal-fired slag. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The embodiment is basically as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown:

[0035] A method for preparing titanium-doped gypsum cement comprises the following steps:

[0036] Step 1, using a preparation device of titanium-doped gypsum cement, including a preparation barrel 1, a first bracket 2 is fixedly connected to the outside of the preparation barrel 1, the first bracket 2 is used to place the preparation barrel 1, the preparation barrel 1 includes an upper batching barrel 3, a middle crushing device and a lower stirring device, the batching barrel 3 includes a plurality of storage bins 6 and a first driving device 4, the first driving device 4 is located above the preparation barrel 1, the first driving device 4 is fixedly connected to the first bracket 2, the storage bin 6 is connected to a first discharge port 5 arranged on the bottom wall of the preparation barrel 1, the first discharge port 5 is provided with an opening and closing device, the opening and closing device includes a chute 27 and a slider 26 both arranged on the bottom wall of the batching barrel 3, the chute is located near the first discharge port 5 On the side of the wall near the preparation barrel 1, the slider 26 slides in cooperation with the slide groove 27, and a spring 28 is fixedly connected to one side of the slider 26, and the other end of the spring 28 is fixedly connected to the slide groove 27. A second bracket 7 is installed under the batching barrel 3, and the second bracket 7 is fixedly connected to the preparation barrel 1. The middle part of the second bracket 7 is fixedly connected to a placement rack 8 for placing the batching barrel 3. The batching barrel 3 is fixedly connected with a central axis 9, and the top end of the central axis 9 is rotationally connected to the driving device through a bevel gear, and the bottom end of the central axis 9 is rotationally matched with the placement rack 8. A material receiving trough 10 is provided at the bottom of the batching barrel 3, and the material receiving trough 10 is fixedly connected to the preparation barrel 1. The upper diameter of the material receiving trough 10 is larger than the lower diameter, and a second discharge port 11 is provided in the middle of the material receiving trough 10.

[0037] In this embodiment, during operation, different raw materials are placed in different storage bins 6. The raw materials are clay, iron powder, limestone and grinding aids, and their mass proportions are: 15 parts of clay, 2 parts of iron powder, 15 parts of limestone and 0.5 parts of grinding aids. The first driving device 4 is used to drive the central axis 9 to rotate so as to rotate the batching barrel 3. When the batching barrel 3 rotates, the slider 26 slides away from the central axis 9 and slides into the chute 27, thereby opening the first discharge port 5. Since the spring coefficients of the springs 28 of different storage bins 6 are different, the sliding distances of the slider 26 are different under the same centrifugal force. The opening degree of the first discharge port 5 is different. The smaller the spring coefficient, the larger the opening of the storage bin 6, the faster the raw material output, and the more raw material output. On the contrary, the larger the spring coefficient, the smaller the opening of the storage bin 6, the slower the raw material output, and the less raw material output. The amount of different raw materials is thereby adjusted. Since the raw materials fall during the rotation process, the fallen raw materials are preliminarily mixed in the receiving trough 10, and the raw materials in the receiving trough 10 are output from the second discharge port 11, thereby automatically performing a more accurate proportioning of the raw materials, reducing the time for manual batching, shortening the preparation period, and increasing labor productivity.

[0038] Step 2, the crushing device includes two relatively rotating crushing cylinders 12, and a first rotating shaft 13 and a second rotating shaft 14 are respectively provided in the middle of the crushing cylinder 12, and blocks 15 are provided on both sides of the axial direction of the crushing cylinder 12, and the blocks 15 are fixedly connected to the preparation barrel 1, and a first motor 16 is installed in the block 15 on one side of the crushing cylinder 12, and the output shaft of the first motor 16 is coaxially fixedly connected to the main gear 17, and the main gear 17 is coaxially fixedly connected to the first rotating shaft 13, and the main gear 17 is meshed with a slave gear 18, and the slave gear 18 is coaxially fixedly connected to the second rotating shaft 14, and the first rotating shaft and the second rotating shaft are both rotated with the block 15 away from the motor. The second outlet 25 is located above the two crushing cylinders 12.

[0039] In this embodiment, during operation, the second output port 25 inputs the raw materials into the middle of the two crushing cylinders 12, and the output shaft of the first motor 16 in the block drives the main gear 17 and the first rotating shaft to rotate. Since the slave gear 18 is engaged with the main gear 17, the main gear 17 drives the slave gear 18 to rotate. As a result, the main gear 17 and the slave gear 18 rotate in different directions, and the two crushing cylinders 12 rotate relative to each other, squeezing the raw materials and crushing them.

[0040] In step three, an arched sieve plate 19 is provided below the crushing device. The lower part of the sieve plate 19 is fixedly connected to the preparation barrel 1. The crushed raw materials fall into the arched part of the sieve plate 19 and are then sieved out from the sieve holes of the sieve plate 19. The raw materials that cannot be sieved out roll to the lower part of the sieve plate 19. A pipe 20 connected to the preparation barrel 1 is provided at the lower part of the sieve plate 19. The other end of the pipe 20 is connected to a sand suction pump 21. The sand suction pump 21 is connected to the material receiving trough 10 away from the end of the pipe 20.

[0041] In this embodiment, during operation, the crushed raw materials fall into the middle of the sieve plate 19, and suitable raw materials are output through the sieve holes. Since the sieve plate 19 is arched, the incompletely crushed raw materials roll to the lower part of the sieve plate 19 and are sucked out by the sand suction pump 21. The sand suction pump 21 sends the incompletely crushed raw materials into the receiving trough 10 and then falls into the crushing device, where the incompletely crushed raw materials are crushed again until the raw materials are completely crushed.

[0042] Step 4. In this embodiment, the stirring device includes a second driving device 22 and a stirring shaft 23. A stirring blade 24 is fixedly connected to the stirring shaft 23. The second driving device 22 drives the stirring shaft 23 to rotate. The second driving device 22 includes an air motor. An outlet 25 connected to the outside is provided at the bottom of the stirring device.

[0043] In this embodiment, during operation, the completely crushed raw materials fall into the stirring device, and the pneumatic motor of the second driving device 22 is used to drive the stirring shaft 23 to rotate. The stirring shaft 23 drives the stirring blades 24 to rotate to pneumatically stir the raw materials in the stirring device, and the stirred raw materials are output from the outlet 25.

[0044] Step 5: The output raw materials are sent to an existing calcining device for calcination to produce clinker.

[0045] Step six, mix and stir the clinker, desulfurization gypsum, titanium gypsum, powder, fly ash and coal-fired slag.
