Description

Technical Field

[0001] The invention relates to the field of cement production equipment, in particular to desulfurized gypsum conveying equipment for cement production. Background Art

[0002] Cement production can generally be divided into main steps such as raw material preparation, clinker calcination, cement grinding and packaging. Gypsum needs to be added during cement grinding to adjust the setting time, increase strength and improve performance. At present, desulfurized gypsum can completely replace natural gypsum as an additive for cement grinding due to its low ingredient cost.

[0003] However, since desulfurized gypsum has a high water content and is easy to stick together, it may affect its fluidity and metering accuracy in the cement production process. Therefore, desulfurized gypsum must be added to the cement grinding ingredients in a reasonable proportion, otherwise it will affect the quality of the cement.

[0004] At present, belt scales are mainly used for quantitative transportation of desulfurized gypsum. The desulfurized gypsum falls continuously and stably from the storage bin onto the belt scale, so that the desulfurized gypsum is continuously weighed through the weighing section of the belt scale with a certain material layer thickness. The conveying speed of the belt scale is automatically adjusted according to the weight signal and speed signal output by the sensor of the belt scale, so that the actual feeding amount closely tracks the process feeding amount, thereby realizing continuous and stable quantitative feeding.

[0005] However, when the existing storage silo drops the desulfurized gypsum onto the belt scale, it is difficult to arrange the desulfurized gypsum evenly on the belt scale. As a result, when the belt scale detects uneven material on it, it is easy for the belt scale to repeatedly adjust its speed, which in turn causes errors in the feeding amount, affects the reasonable proportion of desulfurized gypsum in the cement grinding ingredients, and reduces the quality of cement.

[0006] In addition, when the desulfurization gypsum layer on the belt scale is thick and there is a lot of material, the belt scale reduces the conveying speed in order to ensure the quantitative transportation of the desulfurization gypsum, which prolongs the residence time of the thicker desulfurization gypsum layer on the belt scale, making the desulfurization gypsum prone to compaction and arching, and causing the desulfurization gypsum to be discharged in blocks, making it difficult to control the amount of material discharged, further reducing the quality of cement.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0035] See also Figure 1 and Figure 2 A desulfurized gypsum conveying equipment for cement production comprises a belt scale body 1, a material guide cover 2 is fixedly installed on the upper part of the belt scale body 1, a feeding frame 3 is fixedly installed on the upper part of the material guide cover 2, a material leveling mechanism 4 for evenly arranging the desulfurized gypsum on the belt scale body 1 with the same material layer thickness is arranged inside the material guide cover 2, and a material discharge mechanism 5 for preventing the desulfurized gypsum from becoming slabbed is arranged inside the feeding frame 3.

[0036] When desulfurization gypsum needs to be transported, the desulfurization gypsum is first added to the inside of the feeding frame 3 through the feeding device, and the desulfurization gypsum is quantitatively moved downward through the unloading mechanism 5 to prevent the desulfurization gypsum from accumulating on the belt scale body 1. At the same time, the unloading mechanism 5 can also crush the desulfurization gypsum to prevent the desulfurization gypsum from becoming hardened. Then the material leveling mechanism 4 spreads the desulfurization gypsum evenly on the belt scale body 1, and the desulfurization gypsum is transported to the right through the belt scale body 1. The material leveling mechanism 4 can also scrape the desulfurization gypsum material layer on the belt scale body 1 to a uniform height, thereby facilitating the control of the delivery amount of the desulfurization gypsum.

[0037] See also Figure 2 , Figure 3 and Figure 4The unloading mechanism 5 includes a unloading roller 51 rotatably arranged on the lower side of the feeding frame 3, and storage grooves 52 are provided on the unloading roller 51 at equal intervals along its circumference. The upper inner side of the feeding frame 3 is in a V-shaped structure for gathering the desulfurized gypsum to the unloading roller 51. A No. 1 motor 55 is fixedly installed on the rear side of the feeding frame 3, and the output shaft of the No. 1 motor 55 is fixedly connected to the unloading roller 51.

[0038] When the desulfurized gypsum is located inside the feeding frame 3, the desulfurized gypsum converges downward along the V-shaped structure inside the feeding frame 3 to the upper side of the blanking roller 51 under the action of gravity, and then the No. 1 motor 55 is started, so that the No. 1 motor 55 drives the storage trough 52 on the blanking roller 51 to rotate to an upward position. At this time, the desulfurized gypsum is filled into the storage trough 52 under the action of gravity, and then the blanking roller 51 drives the desulfurized gypsum thereon to rotate downward through the storage trough 52, and then the desulfurized gypsum inside the storage trough 52 falls into the inside of the material guide cover 2 under the action of gravity, thereby completing the quantitative discharge of the desulfurized gypsum inside the feeding frame 3.

[0039] See also Figure 2 and Figure 4 Two sliding plates 53 symmetrically arranged front and back are provided on the inner side of the feeding frame 3 for sliding up and down movement, a licker-in roller 54 is provided for rotating together between the lower parts of the two sliding plates 53, a plurality of guide wheels 551 are provided for rotating at the front side of the feeding frame 3, a belt 552 is wound around the guide wheels 551 and the blanking roller 51, the belt 552 contacts and transmits the front part of the licker-in roller 54, a pushing spring is provided between the upper part of the sliding plate 53 and the feeding frame 3, a pattern plate 56 coaxially arranged therewith is fixedly installed at the front side of the blanking roller 51, and the notch on the pattern plate 56 corresponds one to one to the position of the storage slot 52.

[0040] When the blanking roller 51 rotates, the blanking roller 51 synchronously drives the licker-in roller 54 to rotate through the belt 552, so that the licker-in roller 54 continuously stirs and crushes the desulfurized gypsum inside the feeding frame 3, thereby preventing the desulfurized gypsum from being hardened inside the feeding frame 3. At the same time, the blanking roller 51 drives the pattern plate 56 to rotate synchronously, so that the pattern plate 56 synchronously pushes the licker-in roller 54 upward intermittently with its outer curved surface.

[0041] When the blanking roller 51 drives the storage tank 52 to rotate upward, the blanking roller 51 drives the notch of the pattern plate 56 to also be transmitted upward, so that the push spring pushes the sliding plate 53 downward by its own elastic force, and the sliding plate 53 drives the licker-in roller 54 to move downward to the notch of the pattern plate 56 and the inside of the storage tank 52 at the same time, so that the licker-in roller 54 stirs and crushes the desulfurized gypsum filled in the storage tank 52, which can prevent the desulfurized gypsum from compacting in the storage tank 52 on the one hand, and loosen the desulfurized gypsum in the storage tank 52 on the other hand, increase the fluidity of the desulfurized gypsum in the storage tank 52, so that the desulfurized gypsum can fill the inside of the storage tank 52, thereby increasing the accuracy of quantitative feeding of the desulfurized gypsum.

[0042] See also Figure 2 , Figure 5 and Figure 6 The material equalizing mechanism 4 includes a material shaking plate 41 which is slidably arranged on the left inner side of the material guide cover 2. The material shaking plate 41 is arranged in a posture of being higher on the left and lower on the right. A notch plate 46 is fixedly installed on the left rear part of the material shaking plate 41, and a No. 2 motor 461 is fixedly installed on the left rear part of the material guide cover 2. A rotating disk 462 is fixedly installed on the output shaft of the No. 2 motor 461, and a raised column 463 inserted into the inside of the notch plate 46 and matched with its notch is fixedly installed at the eccentric right side of the rotating disk 462.

[0043] When the desulfurized gypsum falls from the inside of the feeding frame 3 to the inside of the material guide cover 2, the desulfurized gypsum falls onto the shaking plate 41, and at the same time, the No. 2 motor 461 is started to drive the rotating disk 462 to rotate, and the rotating disk 462 pushes the notch plate 46 back and forth through the protruding column 463, so that the notch plate 46 drives the shaking plate 41 to shake back and forth, so that the shaking plate 41 shakes the desulfurized gypsum falling thereon, so that the desulfurized gypsum is evenly arranged on the shaking plate 41, and at the same time, the desulfurized gypsum slides to the lower right along the shaking plate 41 under the action of gravity to the belt scale body 1, so that the desulfurized gypsum is evenly spread on the belt scale body 1 and transported to the right.

[0044] Continue reading Figure 2 , Figure 5 and Figure 6 The shaking plate 41 and the material guide cover 2 are jointly provided with a lifting assembly 42 for lifting the desulfurized gypsum. The lifting assembly 42 includes right-angled trapezoidal blocks 421 arranged on the shaking plate 41 at equal intervals along the front-to-back direction. The right-angled trapezoidal blocks 421 are slidably connected to the shaking plate 41 in a direction perpendicular to the upper side surface of the shaking plate 41. The inclined surfaces of two adjacent right-angled trapezoidal blocks 421 face opposite directions. A fixing plate 422 is fixedly installed on the left inner side of the material guide cover 2, and a plurality of guide portions 423 corresponding to the right-angled trapezoidal blocks 421 are arranged on the right side of the fixing plate 422.

[0045] See also Figure 2 , Figure 6 and Figure 7 The two adjacent guide parts 423 are arranged symmetrically, and the guide part 423 includes a track slot block 4231 fixedly connected to the fixed plate 422, and a push plate 4232 is slidably arranged on the front and rear sides of the track slot block 4231. The two push plates 4232 on the same track slot block 4231 are centrally symmetrically arranged, and a coil spring is arranged between the push plate 4232 and the track slot block 4231. A follower column 4233 sliding inside the track slot block 4231 is fixedly installed at the lower left side of the right-angled trapezoidal block 421. The track slot on the track slot block 4231 is rectangular, and the side of the push plate 4232 close to the center of the track slot block 4231 connected thereto is an inclined structure.

[0046] When the shaking plate 41 shakes back and forth, the shaking plate 41 drives all the right-angled trapezoidal blocks 421 thereon to move synchronously. When the shaking plate 41 moves forward, the shaking plate 41 drives the follower column 4233 thereon to move forward along the track groove of the track groove block 4231 through the right-angled trapezoidal block 421. At this time, the right-angled trapezoidal block 421 arranged with the inclined surface facing forward drives the follower column 4233 thereon to move along the upper horizontal section of the rectangular track groove of the corresponding track groove block 4231. At the same time, the right-angled trapezoidal block 421 arranged with the inclined surface facing backward drives the follower column 4233 thereon to move along the lower horizontal section of the rectangular track groove of the corresponding track groove block 4231.

[0047] As a result, when the right-angled trapezoidal block 421 with the inclined surface facing forward moves forward, its inclined surface part extends to the upper part of the shaking plate 41. Similarly, the inclined surface part of the right-angled trapezoidal block 421 with the inclined surface facing backward shrinks to the inside of the shaking plate 41. When the right-angled trapezoidal block 421 with the inclined surface facing forward moves forward, it scoops up the desulfurized gypsum on the shaking plate 41 through its inclined surface, and then turns over the desulfurized gypsum on the shaking plate 41, thereby further increasing the uniformity of the arrangement of the desulfurized gypsum and loosening the desulfurized gypsum to prevent the desulfurized gypsum from becoming slab-like.

[0048] When the right-angled trapezoidal block 421 drives the follower column 4233 thereon to contact the inclined surface of the push plate 4232 at the corresponding position on its front side, the follower column 4233 pushes the push plate 4232 at the corresponding position on the front side to move away from the track groove block 4231, and at the same time compresses the coil spring at the corresponding position. When the shaking plate 41 moves forward to the maximum stroke position, the follower column 4233 moves forward to the vertical section position on the front side of the rectangular track groove of the track groove block 4231.

[0049] Thereby, the spiral spring at the corresponding position pushes the pushing plate 4232 through its own elastic force, and then the pushing plate 4232 pushes the follower column 4233 originally located at the upper horizontal section of the rectangular track groove of the track groove block 4231 to the lower horizontal section of the rectangular track groove of the track groove block 4231, and at the same time pushes the follower column 4233 originally located at the lower horizontal section of the rectangular track groove of the track groove block 4231 to the upper horizontal section of the rectangular track groove of the track groove block 4231.

[0050] This is so that the inclined surface part of the right-angled trapezoidal block 421 arranged with the inclined surface facing forward can be retracted into the inside of the shaking plate 41, and the inclined surface part of the right-angled trapezoidal block 421 arranged with the inclined surface facing backward can be extended to the upper part of the shaking plate 41, so that when the shaking plate 41 moves backward, the desulfurized gypsum can be continuously turned over and loosened by the right-angled trapezoidal block 421 arranged with the inclined surface facing backward.

[0051] See also Figure 2 , Figure 8 and Fig. 9 A scraper frame 43 is fixedly installed on the middle part of the inner side of the material guide cover 2, and a sieve plate 44 is fixedly installed on the lower right side of the scraper frame 43. The scraper frame 43 and the material guide cover 2 are jointly provided with a pushing assembly 45 for evenly arranging the desulfurized gypsum on the sieve plate 44. The pushing assembly 45 includes a material pushing part 454. A No. 3 motor 453 is fixedly installed on the inner rear part of the material guide cover 2.

[0052] Continue reading Figure 2 , Figure 8 and Fig. 9 The material-moving portion 454 includes two rotating rods 4541 rotatably arranged inside the material guide cover 2, a conveyor belt 4542 with a plurality of shifting rods arranged on the outer side is wound around the two rotating rods 4541, the rotating rod 4541 on the left is fixedly connected to the output shaft of the third motor 453, the left side of the material guide cover 2 is an inclined structure, the conveyor belt 4542 is parallel to the inclined structure of the material guide cover 2 and is arranged on the upper part of the inclined structure of the material guide cover 2.

[0053] When the desulfurized gypsum falling from the shaking plate 41 onto the belt scale body 1 is transported to the position of the scraper frame 43 by the belt scale body 1, the No. 3 motor 453 is started to drive the left rotating rod 4541 to rotate, and the rotating rod 4541 drives the conveyor belt 4542 to rotate, so that the lower part of the conveyor belt 4542 moves to the right. When the material layer of the desulfurized gypsum is higher than the bottom of the scraper frame 43, the scraper frame 43 shovels the super-high part of the desulfurized gypsum through the inclined surface thereon to between the inclined surface of the scraper frame 43 and the conveyor belt 4542, and then the conveyor belt 4542 drives the desulfurized gypsum to the upper part of the screen plate 44.

[0054] Thereby, the higher part of the desulfurized gypsum material layer can be leveled. By shoveling up the super-high part of the desulfurized gypsum, the material layer can be leveled and the pushing of the desulfurized gypsum material layer can be prevented, so as to avoid pushing the desulfurized gypsum material layer tightly, ensure the looseness of the desulfurized gypsum material layer, and prevent the desulfurized gypsum from becoming compacted.

[0055] See also Figure 8 and Fig. 9 The pushing assembly 45 also includes an L-shaped rod 451 which is slidably arranged on the right side of the scraper frame 43. The upper part of the horizontal section of the L-shaped rod 451 is a pointed structure, and the lower part of the horizontal section of the L-shaped rod 451 is a rectangular structure. The L-shaped rod 451 is located on the upper part of the screen plate 44 and there is a gap between the L-shaped rod 451 and the screen plate 44. A reciprocating screw 452 is rotatably arranged on the right side of the inner side of the material guide cover 2. The reciprocating screw 452 is threadedly connected to the vertical section of the L-shaped rod 451, and the rotating rod 4541 on the right side is connected to the reciprocating screw 452 through a transmission belt.

[0056] As the conveyor belt 4542 rotates, it drives the rotating rod 4541 on the right to rotate synchronously. The rotating rod 4541 on the right drives the reciprocating screw 452 to rotate. The reciprocating screw 452 drives the horizontal section of the L-shaped rod 451 to move back and forth on the upper part of the sieve plate 44, so that the L-shaped rod 451 pushes the desulfurized gypsum to be spread flat on the sieve plate 44. When the desulfurized gypsum layer whose height is flush with the bottom of the scraper frame 43 moves to the bottom of the sieve plate 44, the desulfurized gypsum layer blocks the sieve holes of the sieve plate 44 to prevent the desulfurized gypsum on the sieve plate 44 from leaking down.

[0057] When the desulfurized gypsum layer below the bottom of the scraper frame 43 moves to the bottom of the sieve plate 44, the desulfurized gypsum on the sieve plate 44 drives the sieve holes of the sieve plate 44 under the action of gravity to fill the desulfurized gypsum layer below the bottom of the scraper frame 43, so that the height of the desulfurized gypsum layer passing through the sieve plate 44 is uniform, ensuring the accuracy of the weighing of the desulfurized gypsum by the belt scale body 1, thereby further ensuring the accuracy of the feeding amount, and the screening of the desulfurized gypsum by the sieve plate 44 can also prevent the agglomerated desulfurized gypsum from falling into the desulfurized gypsum layer.

[0058] Then the belt scale body 1 drives the desulfurized gypsum material layer to move rightward to the weighing section passing through it, and the weight signal and speed signal output by the sensor of the belt scale body 1 automatically adjust the conveying speed of the belt scale body 1, so as to accurately convey the required amount of desulfurized gypsum to the desired location.

[0059] When conveying desulfurized gypsum, the present invention also includes the following steps: the first step is to add desulfurized gypsum into the feeding frame 3 through the feeding device, and the desulfurized gypsum is gathered to the upper side of the blanking roller 51 under the action of gravity, and the No. 1 motor 55 is started to make the pricking roller 54 stir and crush the desulfurized gypsum in the storage tank 52 and the feeding frame 3.

[0060] In the second step, the rotating blanking roller 51 drives the desulfurized gypsum thereon to rotate downward through the storage trough 52, and then the desulfurized gypsum inside the storage trough 52 falls into the inside of the material guide cover 2 under the action of gravity, thereby completing the quantitative blanking of the desulfurized gypsum inside the feeding frame 3.

[0061] In the third step, the desulfurized gypsum falls from the inside of the feeding frame 3 to the shaking plate 41, and the No. 2 motor 461 is started to drive the shaking plate 41 to shake the desulfurized gypsum, so that the desulfurized gypsum is evenly arranged on the shaking plate 41. At the same time, the desulfurized gypsum is continuously turned over and loosened by the inclined part of the right-angle trapezoidal block 421 to prevent the desulfurized gypsum from becoming slab-like.

[0062] In the fourth step, the desulfurized gypsum slides to the lower right along the shaking plate 41 to the belt scale body 1 under the action of gravity. The belt scale body 1 transports the desulfurized gypsum to the right to the position of the scraper frame 43. The scraper frame 43 scoops up the super-high part of the desulfurized gypsum and drives the conveyor belt 4542 to drive the desulfurized gypsum to the upper part of the screen plate 44 through the No. 3 motor 453.

[0063] In the fifth step, the conveyor belt 4542 drives the L-shaped rod 451 through the reciprocating screw 452 to push the desulfurized gypsum to be spread flat on the sieve plate 44. When the desulfurized gypsum layer below the bottom of the scraper frame 43 moves to the bottom of the sieve plate 44, the desulfurized gypsum on the sieve plate 44 drives the sieve holes of the sieve plate 44 under the action of gravity to fill the desulfurized gypsum layer below the bottom of the scraper frame 43, thereby making the height of the desulfurized gypsum layer passing through the sieve plate 44 uniform.

[0064] In the sixth step, the belt scale body 1 drives the desulfurized gypsum material layer to move rightward to the weighing section passing through it, and the weight signal and speed signal output by the sensor of the belt scale body 1 automatically adjust the conveying speed of the belt scale body 1, so as to accurately convey the required amount of desulfurized gypsum to the desired location.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
