Description

Technical Field

[0002] The rotary kiln is a commonly used gypsum calcining equipment. The gypsum raw materials are slowly moved from the inlet to the outlet through the slow rotation of the rotary kiln and the height difference between the inlet and the outlet. In this process, the gypsum raw materials are calcined. The gypsum raw materials are not fully crushed or the gypsum raw materials are agglomerated due to high water content, causing large pieces of raw materials to enter the rotary kiln. The large pieces of raw materials are dehydrated by heat, and the outer layer of water evaporates to form a hard shell, making it difficult for the internal water to escape quickly.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] The present invention provides Figure 1-13 An integrated gypsum calcining device shown includes a frame 1 and a cylinder 2 located above the frame 1, and further includes: The feed end 3 and the discharge end 4 are respectively fixed on both sides of the top of the frame 1, and the cylinder 2 is located between the feed end 3 and the discharge end 4. The two ends of the cylinder 2 are rotatably connected to the feed end 3 and the discharge end 4 respectively; It should be noted that the gypsum raw material enters the interior of the cylinder 2 through the feed end 3 and is calcined inside the cylinder 2. The calcined gypsum clinker is discharged through the discharge end 4, and the discharge end 4 is rotatably connected to the feed end 3 and the discharge end 4, so that the cylindrical cylinder 2 can rotate freely to facilitate better transportation of the gypsum raw material. At the same time, it has a certain turning effect on the gypsum raw material inside it, so that the gypsum raw material is heated more evenly.

[0034] A driving support assembly 5, which is located between the frame 1 and the cylinder 2 and is used to support the cylinder 2 and drive the cylinder 2 to rotate; It should be noted that the feed end 3 and the discharge end 4 support the two ends of the cylinder 2, which will cause the middle part of the cylinder 2 to be suspended in the air. The driving support assembly 5 can be supported on the middle part of the cylinder 2 to prevent the cylinder 2 from bending due to gravity, thereby affecting the transmission of the gypsum raw material in the cylinder 2.

[0035] A heating assembly 6 is provided outside the cylinder 2 and is used to heat and calcine the gypsum raw material inside the cylinder 2; It should be noted that the heating assembly 6 is sleeved on the outside of the cylinder 2 and can heat the cylinder 2 in all directions, thereby calcining the gypsum raw material inside the cylinder 2.

[0036] The crushing mechanism 7 is located at one end of the cylinder 2 close to the feed end 3. The crushing mechanism 7 includes a rotary screening assembly 71, a transmission assembly 72, a shearing crushing assembly 73, a cone plate crushing assembly 74 and a cone plate cleaning assembly 75.

[0037] It should be noted that the gypsum raw material enters one end of the cylinder 2 from the feed end 3, and the agglomerated and blocky gypsum raw material is crushed by the crushing mechanism 7; Among them, the rotary screening component 71 can screen the gypsum raw materials, and screen out the clumped and blocky gypsum raw materials from the finely crushed gypsum raw materials, and the transmission component 72 is used to drive the rotary screening component 71 to perform screening. The shearing and crushing component 73 is a primary crushing component, which can crush large pieces of gypsum raw materials. The cone plate crushing component 74 is a secondary crushing component, which can perform secondary crushing to further improve the crushing effect. Finally, the cone plate cleaning component 75 can clean the gypsum raw materials that may be adhered to the cone plate crushing component 74 to avoid overburning of the gypsum raw materials due to being in the cylinder 2 for a long time.

[0038] The cylinder 2 is tilted, and the height of the cylinder 2 near the feed end 3 is greater than the height of the cylinder 2 near the discharge end 4.

[0039] It should be noted that the end of the cylinder 2 close to the feed end 3 is the inlet, and the end close to the discharge end 4 is the outlet. The inlet of the cylinder 2 is higher than the outlet, so that the end of the cylinder 2 close to the discharge end 4 is tilted downward, and the driving support assembly 5 drives the cylinder 2 to rotate, so that the gypsum raw material can slowly move toward the outlet after entering from the inlet of the cylinder 2. During the movement of the gypsum raw material, the gypsum raw material is continuously calcined.

[0040] The feeding end 3 includes a front bracket 31, which is fixed to the top of the frame 1. One end of the cylinder 2 extends into the front bracket 31 and is rotatably connected to the front bracket 31. A feeding hopper 32 is installed on the top of the front bracket 31. The bottom of the feeding hopper 32 is connected to a conveying channel 33. The conveying channel 33 extends into the interior of the cylinder 2 away from the end of the feeding hopper 32. The discharge end 4 includes a rear bracket 41, which is fixed to the top of the frame 1. The end of the cylinder 2 away from the front bracket 31 extends into the interior of the rear bracket 41 and is rotatably connected to the rear bracket 41. A material receiving trough 42 is fixedly connected to one side of the rear bracket 41. One end of the material receiving trough 42 extends into the interior of the rear bracket 41. The material receiving trough 42 is located below the cylinder 2 and is arranged at an angle.

[0041] It should be noted that the front bracket 31 is supported at one end of the cylinder 2, and the gypsum raw material enters from the feed hopper 32 and then enters the interior of the cylinder 2 through the conveying channel 33 at its bottom; In addition, the rear bracket 41 is supported at the other end of the cylinder 2. After the gypsum raw material is discharged from one end of the cylinder 2, it falls onto the receiving trough 42. Since the receiving trough 42 is inclined, the gypsum clinker falling onto the receiving trough 42 slides toward one end of the receiving trough 42.

[0042] The driving support assembly 5 includes multiple support seats 51, and the outer part of the cylinder 2 is provided with a driven gear ring 55 and multiple support rings 52. The support seat 51 corresponds to the support ring 52 and the driven gear ring 55. The bottom of the support ring 52 is provided with a support roller 53, and the support roller 53 corresponds to the support ring 52. The support roller 53 is installed on the top of the support seat 51, and the bottom of the driven gear ring 55 is engaged with a driven gear 54. The driven gear 54 is installed inside the support seat 51, and the bottom of the driven gear 54 is engaged with a transmission gear 57. A drive motor 56 is provided on one side of the transmission gear 57. The output shaft of the drive motor 56 is fixedly connected to the transmission gear 57, and the drive motor 56 is fixed on one side of the support seat 51.

[0043] It should be noted that the support roller 53 is supported on the bottom of the support ring 52, and the support ring 52 can support the cylinder 2, and the support ring 52 can roll on the support roller 53, which can reduce the rotation resistance of the cylinder 2 and reduce energy consumption; In addition, the output shaft of the driving motor 56 drives the transmission gear 57 fixed thereto, and the transmission gear 57 drives the driven gear 54 meshing therewith, and then the driven gear 54 drives the driven ring gear 55, driving the barrel 2 fixed to the driven ring gear 55 to rotate.

[0044] The heating assembly 6 includes a support frame 61 and an electric heating ring 62. The electric heating ring 62 is fixed on the top of the support frame 61. The electric heating ring 62 is sleeved on the outside of the cylinder 2. The support frame 61 is fixed on the top of the frame 1. The number of the electric heating ring 62 is set to multiple.

[0045] It should be noted that, by setting the electric heating ring 62, the cylinder 2 can be heated in sections, and the heating temperature of the cylinder 2 can be adjusted in sections according to the calcination condition of the gypsum raw material, which is beneficial to improving the calcination effect of the gypsum raw material.

[0046] The rotary screening assembly 71 includes a baffle 711, which is arranged inside the cylinder 2 and rotatably connected to the cylinder 2. The baffle 711 is fixedly connected to the front bracket 31 through a bracket. One end of the conveying channel 33 passes through the baffle 711 and is fixedly connected to the baffle 711. A ring frame 712 is installed inside the cylinder 2. A rotating shaft 713 is provided between the baffle 711 and the ring frame 712. Both ends of the rotating shaft 713 are rotatably connected to the baffle 711 and the ring frame 712 respectively. A plurality of screening plates 714 are arranged in a ring shape on the outside of the rotating shaft 713. Two connecting plates 715 are fixedly connected between the screening plate 714 and the rotating shaft 713. Screening teeth 716 are provided on one side of the screening plate 714, and the screening teeth 716 slide inside the cylinder 2.

[0047] It should be noted that the gypsum raw material enters one end of the cylinder 2 and gradually moves toward the other end of the cylinder 2 as the cylinder 2 rotates. At the same time, the rotating shaft 713 rotates, and then drives the screen plate 714 connected thereto to rotate through the connecting plate 715, so that the screening teeth 716 at one end of the screen plate 714 slide on the inner wall of the cylinder 2. In this way, the gypsum raw material entering the cylinder 2 is screened, and the clumped and blocky gypsum raw materials are screened out. In addition, the setting of the baffle 711 can cooperate with the ring frame 712 to support the rotating shaft 713. Moreover, the baffle 711 can also block the cylinder 2 to prevent the gypsum raw material near the entrance of the cylinder 2 from splashing out of the cylinder 2.

[0048] The transmission assembly 72 includes an inner ring gear 721, which is fixed to the inside of the cylinder 2. The inner side of the inner ring gear 721 is meshed with a connecting gear 722, and the connecting gear 722 is installed on one side of the baffle 711. The outside of the rotating shaft 713 is fixedly connected to a center gear 723, and the center gear 723 is meshed with the connecting gear 722. The center gear 723 is set on the side of the baffle 711 away from the center of the cylinder 2.

[0049] It should be noted that the inner gear ring 721 rotates with the cylinder 2, while the baffle 711 is connected to the front bracket 31 through the bracket and will not rotate with the cylinder 2. The inner gear ring 721 is engaged with the connecting gear 1 722, so that the inner gear ring 721 drives the connecting gear 1 722 to rotate, and then the connecting gear 1 722 drives the center gear 723 engaged with it to rotate, and the center gear 723 rotates in the opposite direction to the inner gear ring 721, and then drives the rotating shaft 713 fixedly connected to the center gear 723 to rotate, so that the rotary screening assembly 71 screens the gypsum raw material.

[0050] The shearing and crushing assembly 73 includes a driving shaft 731, and both ends of the driving shaft 731 respectively pass through two connecting plates 715 and are rotatably connected to the connecting plates 715. A plurality of shear rods 732 are provided on the outside of the driving shaft 731, and the shear rods 732 are provided inside the screening teeth 716. The shear rods 732 correspond to the screening teeth 716. The inside of the cylinder 2 is fixedly connected to the inner ring gear 2 733, and the inner ring gear 2 733 is provided on the side of the baffle 711 away from the inner ring gear 1 721. One end of the driving shaft 731 is fixedly connected to the connecting gear 2 734, and the connecting gear 2 734 is meshed with the inner ring gear 2 733.

[0051] It should be noted that the rotating shaft 713 drives the screening teeth 716 to screen the gypsum raw materials inside the cylinder 2. At this time, the clumped and blocky gypsum raw materials gather on the surface of the screening teeth 716, and the driving shaft 731 rotates with the connecting plate 715, causing the connecting gear 2 734 to rotate around the inner ring gear 2 733. Since the connecting gear 2 734 is engaged with the inner ring gear 2 733, the connecting gear 2 734 rotates. The rotation of the connecting gear 2 734 drives the drive shaft 731 fixedly connected to it to rotate, and then drives the shear rod 732 to rotate, so that the shear rod 732 cooperates with the screening teeth 716 to shear the clumped and blocky gypsum raw materials that have been screened out, and break the large pieces of gypsum raw materials into small pieces. The fine gypsum raw materials will leak out from the gaps in the screening teeth 716.

[0052] The cone-plate crushing assembly 74 includes a material-ejecting inclined plate 741, which is fixed on one side of the connecting plate 715. A material receiving plate 742 is provided on one side of the material-ejecting inclined plate 741. The material receiving plate 742 is provided between the two connecting plates 715. A support spring 744 is provided between the material receiving plate 742 and the connecting plate 715. A plurality of crushing cones 743 are fixedly connected to one side of the material receiving plate 742.

[0053] It should be noted that the gypsum raw materials screened by the shearing and crushing assembly 73 are gradually lifted as the screening plate 714 rotates, and the gypsum raw materials are lifted to a high position. The angle of the screening plate 714 gradually tilts toward the direction of the throwing inclined plate 741, and the gypsum raw materials slide into the throwing inclined plate 741, and are then thrown out from the edge of the throwing inclined plate 741. The thrown gypsum raw materials will fall on the surface of the receiving plate 742 below it. By providing a crushing cone 743 on the surface of the receiving plate 742, the fallen gypsum raw materials can be crushed to avoid uneven calcination caused by agglomeration of the gypsum raw materials. In addition, through the setting of the support spring 744, when the gypsum raw material falls on the receiving plate 742, the receiving plate 742 will vibrate, which can knock down the gypsum raw material stuck in the gap of the crushing cone 743, thereby preventing the gypsum raw material from staying inside the cylinder 2 for a long time and causing overburning.

[0054] The cone plate cleaning assembly 75 includes a rocker 751, the cross-sectional shape of the rocker 751 is set to be V-shaped, the middle section of the rocker 751 is hinged to the connecting plate 715, one end of the rocker 751 is fixedly connected to a knock hammer 752, the other end of the rocker 751 corresponds to the shear rod 732, the knock hammer 752 corresponds to the material receiving plate 742, and a reset spring 753 is fixedly connected between the end of the rocker 751 close to the knock hammer 752 and the ejection inclined plate 741.

[0055] When the cam 752 is in the closed position, the cam 753 is in the closed position, and the cam 753 is in the closed position, so that the cam 753 is in the closed position, and the cam 753 is in the closed position, so that the cam 753 is in the closed position, and the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam 753 is in the closed position, so that the cam

[0056] Working principle of the present invention: Refer to the instruction manual Figure 1-13 First, the gypsum raw material enters from the feed hopper 32 at the top of the front bracket 31, and then passes through the conveying channel 33, so that the gypsum raw material passes through the baffle 711 and enters the interior of the cylinder 2; The output shaft of the driving motor 56 drives the transmission gear 57 to rotate, and then drives the driven gear 54 meshing with it to rotate, so that the driven gear 54 drives the driven ring gear 55, and the driven ring gear 55 drives the cylinder 2 to rotate; The electric heating ring 62 is started to heat the cylinder 2 inside the electric heating ring 62, thereby calcining the gypsum raw material inside the cylinder 2; As the cylinder 2 rotates, the inner ring gear 721 is driven to rotate, and then the central gear 723 is driven by the connecting gear 722, so that the central gear 723 drives the rotating shaft 713 to rotate; As the rotating shaft 713 rotates, the screening teeth 716 are driven to screen the gypsum raw materials inside the cylinder 2. At this time, the agglomerated and blocky gypsum raw materials gather on the surface of the screening teeth 716. The driving shaft 731 rotates along with the connecting plate 715, causing the connecting gear 2 734 to rotate around the inner ring gear 2 733, which in turn drives the driving shaft 731 to rotate, causing the shear rod 732 to rotate. The shear rod 732 cooperates with the screening teeth 716 to shear the agglomerated and blocky gypsum raw materials that have been screened out. The gypsum raw materials screened by the shearing and crushing assembly 73 are gradually lifted as the screening plate 714 rotates. The gypsum raw materials slide into the throwing inclined plate 741 and are then thrown out from the edge of the throwing inclined plate 741. The thrown gypsum raw materials fall onto the crushing cone 743 on the surface of the receiving plate 742 below it, which can crush the fallen gypsum raw materials and avoid uneven calcination caused by the agglomeration of the gypsum raw materials. In addition, the shear rod 732 will continuously toggle one end of the rocker 751 while rotating, and the rocker 751 drives the knocking hammer 752 to reset, so that the knocking hammer 752 hits the receiving plate 742, causing the receiving plate 742 to vibrate, and the gypsum material stuck in the gap of the crushing cone 743 can be knocked down. At the same time, due to the setting of the supporting spring 744, when the gypsum material falls on the receiving plate 742, the receiving plate 742 will vibrate, and the gypsum material stuck in the gap of the crushing cone 743 can be knocked down, thereby preventing the gypsum material from staying in the cylinder 2 for a long time and causing overburning. Finally, with the height difference between the two ends of the cylinder 2 and the rotation of the cylinder 2, the gypsum raw material inside the cylinder 2 gradually moves toward the discharge end 4, and finally falls off the cylinder 2 and falls into the receiving trough 42 to be discharged.

[0057] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
