Description

Technical Field

[0001] The invention relates to the technical field of hammer type dispersing machines, and in particular to a dehydrating hammer type dispersing machine. Background Art

[0002] In the production process of gypsum board, the raw material of cooked gypsum used is obtained by calcining and dehydrating desulfurized gypsum. The main process is that the desulfurized gypsum is dehydrated by hot air in a hammer-type disperser to remove the surface water, and then enters the calcining furnace to remove the crystallization water of the desulfurized gypsum.

[0003] At present, when a hammer type dispersing machine is used to dehydrate desulfurized gypsum, hot air is only introduced into the ordinary hammer type dispersing machine to dehydrate the desulfurized gypsum. The existing hammer type dispersing machine mainly crushes the desulfurized gypsum, and the overall dehydration and drying effect is poor, so that the desulfurized gypsum is not fully and uniformly dehydrated. Summary of the invention

[0004] The object of the present invention is to provide a dehydration hammer type dispersing machine to solve the technical problem that the dehydration effect of the hammer type dispersing machine in the prior art is poor.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0006] A dehydrating hammer type dispersing machine, comprising:

[0007] A casing, wherein a rotating shaft and a hammer head connected to the outer surface of the rotating shaft are provided inside the casing, and a plurality of first hot air pipes are provided on the rotating shaft, wherein the first hot air pipes blow hot air toward the desulfurized gypsum inside the casing to dehydrate the desulfurized gypsum being crushed inside the casing;

[0008] A feed channel is arranged at a feed end on the top of the casing, and a plurality of second hot air pipes are arranged inside the feed channel. The second hot air pipes blow hot air to blow the unbroken desulfurized gypsum into the casing and dehydrate the unbroken desulfurized gypsum;

[0009] A discharge channel is arranged at the discharge end at the bottom of the casing, and a fan is arranged on one side of the discharge channel. The fan input end is connected to the bottom of the discharge channel. The fan forms a low-pressure area at the bottom of the discharge channel, so that the hot air inside the casing moves to the discharge channel. The moving hot air then dehydrates the desulfurized gypsum being discharged after being crushed.

[0010] Among them, the fan output end is connected to the second hot air duct, and the external hot air enters the casing through the first hot air duct, and then moves toward the discharge channel. The hot air that moves to the bottom of the discharge channel is transported to the second hot air duct by the fan to realize hot air circulation.

[0011] Furthermore, the center of the rotating shaft is set to be hollow, the first hot air pipe is connected to the inside of the rotating shaft, and the outside hot air is introduced into the inside of the rotating shaft. The first hot air pipe makes a circular motion as the rotating shaft rotates, so that the hot air blown out by the first hot air pipe makes a circular motion, thereby blowing towards the desulfurized gypsum that is being crushed inside the casing.

[0012] Furthermore, the casing includes an inner casing and an outer casing, and a cavity is formed between the inner casing and the outer casing, the cavity is connected to the output end of the fan, and an exhaust pipe connected to the cavity is connected to one side of the casing. The gas discharged from the discharge channel is transported to the inside of the cavity through the fan part, and the casing is heated to increase its temperature, thereby heating and drying the desulfurized gypsum that is being crushed inside the casing.

[0013] Further, the feed channel includes an inlet channel, the inlet channel is arranged to be inclined downward, and the angle between the inlet channel and the horizontal plane is 20-30 degrees;

[0014] A plurality of the second hot air pipes are evenly arranged on the inner wall of the inlet channel, and the second hot air pipes on the inlet channel are all inclinedly arranged, and the hot air from the second hot air pipes transports the desulfurized gypsum at the inlet channel downstream, while drying and dehydrating the desulfurized gypsum.

[0015] Furthermore, a vertically arranged feed pipe is provided at the input end of the inlet channel, and a push block is provided on one side of the bottom of the feed pipe. The push block is arranged on the opposite side of the inlet channel. The push block is controlled by a hydraulic rod to approach or move away from the inlet channel. The desulfurized gypsum at the bottom of the feed pipe is moved to the end of the inlet channel by the push of the push block, and then the hot air force of the second hot air pipe transports the desulfurized gypsum at the inlet channel downstream.

[0016] Furthermore, a rotating shaft and a rotating plate fixed on the outer surface of the rotating shaft are provided between the inlet channel and the feed pipe. The vertical cross-section of the rotating plate is arranged to be arc-shaped. The rotating plate rotates with the rotation of the rotating shaft, thereby scooping up the desulfurized gypsum pushed to the end of the inlet channel by the pushing block and throwing it into the inlet channel, thereby transporting and dispersing the desulfurized gypsum.

[0017] Furthermore, the feed channel further comprises a feed channel, the feed channel is arranged between the inlet channel and the casing, the feed channel is arranged in an inclined shape, and the angle between the feed channel and the horizontal plane is greater than the angle between the inlet channel and the horizontal plane;

[0018] A plurality of the second hot air pipes are evenly arranged on the inner wall of the material discharge channel, and the second hot air pipes on the material discharge channel are all inclinedly arranged;

[0019] A plurality of wire meshes are arranged inside the discharge channel, and the desulfurized gypsum falling from the inlet channel to the discharge channel is dispersed multiple times after passing through the plurality of wire meshes. The hot air blown out from the second hot air pipe accelerates the falling of the desulfurized gypsum while drying and dehydrating the desulfurized gypsum.

[0020] Furthermore, the wire mesh is fixedly connected to the feeding channel by a spring, and the vertical cross section of the wire mesh is configured to be wavy to increase the contact area between the desulfurized gypsum and the wire mesh;

[0021] When the desulfurized gypsum falling from the inlet channel passes through the wire mesh, it is dispersed by the wire mesh and exerts force on the wire mesh. The elastic force of the spring causes the wire mesh to continue to shake and disperse the desulfurized gypsum again.

[0022] Furthermore, a screen is provided at the bottom of the casing, and the crushed desulfurized gypsum falls into the discharge channel through the screen;

[0023] An inverted V-shaped dispersion cover is provided inside the discharge channel, and a V-shaped flow guide cover is provided at the bottom of the dispersion cover, the two sides of the flow guide cover are connected to the inner wall of the discharge channel, and a discharge port is provided in the middle of the flow guide cover;

[0024] The desulfurized gypsum that passes through the screen and falls into the discharge channel is evenly dispersed by the dispersion hood, and then collected by the guide hood and discharged.

[0025] Furthermore, sealing plates are hinged on both sides of the bottom of the discharge channel, and telescopic rods are provided on both sides of the bottom of the discharge channel. In the initial state, the output end of the telescopic rod is stretched, and the telescopic rod exerts a force on the sealing plate, so that the sealing plate seals the discharge channel. When discharge is required, the output end of the telescopic rod contracts, and the sealing plate automatically rotates downward under the action of gravity, so that the desulfurized gypsum inside the discharge channel is discharged.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention not only has hot air inside the casing, but also has flowing hot air inside the feed channel and the discharge channel. The desulfurized gypsum is dried with hot air three times before, during and after crushing. During the whole process of crushing the desulfurized gypsum, the water attached to the surface of the desulfurized gypsum is removed, so that the dehydration of the desulfurized gypsum is more uniform and sufficient. At the same time, the fan is provided to realize the recycling of hot air. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1 and Figure 2 As shown, the present invention provides a dehydration hammer type scattering machine, comprising:

[0038] A casing 1, wherein a rotating shaft 2 and a hammer head 3 connected to the outer surface of the rotating shaft 2 are provided inside the casing 1, and a plurality of first hot air pipes 4 are provided on the rotating shaft 2, wherein the first hot air pipes 4 blow hot air toward the desulfurized gypsum inside the casing 1 to dehydrate the desulfurized gypsum being crushed inside the casing 1;

[0039] A feed channel 5 is provided at a feed end on the top of the casing 1, and a plurality of second hot air pipes 6 are provided inside the feed channel 5. The second hot air pipes 6 blow hot air to blow the unbroken desulfurized gypsum into the casing 1, and dehydrate the unbroken desulfurized gypsum;

[0040] A discharge channel 7 is arranged at the discharge end at the bottom of the casing 1. A fan 8 is arranged on one side of the discharge channel 7. The input end of the fan 8 is connected to the bottom of the discharge channel 7. The fan 8 forms a low-pressure area at the bottom of the discharge channel 7, so that the hot air inside the casing 1 moves to the discharge channel 7. The moving hot air then dehydrates the desulfurized gypsum being discharged after being crushed.

[0041] Among them, the output end of the fan 8 is connected to the second hot air duct 6, and the external hot air enters the inside of the casing 1 through the first hot air duct 4, and then moves toward the discharge channel 7. The hot air moved to the bottom of the discharge channel 7 is transported by the fan 8 to the inside of the second hot air duct 6 to realize hot air circulation.

[0042] At present, when a hammer disperser is used to dehydrate desulfurized gypsum, hot air is simply introduced into the ordinary hammer disperser to dehydrate the desulfurized gypsum. The existing hammer disperser mainly crushes the desulfurized gypsum, and the overall dehydration and drying effect is poor, which makes the desulfurized gypsum not fully and uniformly dehydrated. Therefore, it is necessary to develop a dehydration hammer disperser.

[0043] In this embodiment, not only hot air is provided inside the casing 1, but also flowing hot air is provided inside the feed channel 5 and the discharge channel 7. The desulfurized gypsum is dried with hot air three times before, during and after crushing. During the whole process of crushing the desulfurized gypsum, the water attached to the surface of the desulfurized gypsum is removed, so that the dehydration of the desulfurized gypsum is more uniform and sufficient. At the same time, the fan 8 is provided to realize the recycling of hot air.

[0044] In actual use, 1. Feed dehydration, the desulfurized gypsum enters the interior of the casing 1 through the feed channel 5, and the second hot air pipe 6 inside the feed channel 5 blows hot air to blow the unbroken desulfurized gypsum into the interior of the casing 1, and dehydrates the unbroken desulfurized gypsum;

[0045] 2. Crushing and dehydration: the desulfurized gypsum that has entered the casing 1 and has undergone feed dehydration is crushed by the hammer 3 inside the casing 1. During the crushing, the first hot air pipe 4 blows hot air to the desulfurized gypsum inside the casing 1 to dehydrate the desulfurized gypsum that is being crushed inside the casing 1;

[0046] 3. Discharge dehydration: the crushed desulfurized gypsum enters the discharge channel 7. Since a fan 8 is provided, a low-pressure area is formed at the bottom of the discharge channel 7 through the fan 8, so that the hot air inside the casing 1 moves to the discharge channel 7. The hot air moving inside the discharge channel 7 dehydrates the crushed desulfurized gypsum being discharged;

[0047] The three dehydration processes in the above three stages make the dehydration of the desulfurized gypsum more uniform, and through the action of the fan 8, the hot air inside the casing 1 dries the desulfurized gypsum in the process of crushing, and then moves to the discharge channel 7 to dehydrate the desulfurized gypsum in the discharge process, and then enters the second hot air pipe 6 to dry and dehydrate the desulfurized gypsum in the feed channel 5, thereby realizing the recycling of hot air.

[0048] As a preferred embodiment of the present embodiment, the center of the rotating shaft 2 is set to be hollow, the first hot air pipe 4 is connected to the inside of the rotating shaft 2, and the outside hot air is introduced into the inside of the rotating shaft 2. The first hot air pipe 4 makes a circular motion as the rotating shaft 2 rotates, so that the hot air blown out by the first hot air pipe 4 makes a circular motion, thereby blowing towards the desulfurized gypsum that is being crushed inside the casing 1.

[0049] In order to improve the overall drying effect of the device, further, as Figure 5 As shown, the casing 1 includes an inner casing 9 and an outer casing 10, and a cavity 11 is formed between the inner casing 9 and the outer casing 10, the cavity 11 is communicated with the output end of the fan 8, and one side of the casing 1 is connected to an exhaust pipe communicated with the cavity 11, and the gas discharged from the discharge channel 7 is partially transported to the inside of the cavity 11 through the fan 8, and the casing 1 is heated to increase its temperature, thereby heating and drying the desulfurized gypsum that is being crushed inside the casing 1.

[0050] By providing the cavity 11 and introducing the exhaust gas discharged from the discharge channel 7 into the cavity 11, the casing 1 is heated, and when the crushed desulfurized gypsum contacts the casing 1, the casing 1 dries and dehydrates the desulfurized gypsum, thereby improving the dehydration efficiency of the desulfurized gypsum.

[0051] The structure of the feed channel 5 is described in detail below. Figure 2 and Figure 3 As shown, the feed channel 5 includes an inlet channel 12, and the inlet channel 12 is arranged to be inclined downward, and the angle between the inlet channel 12 and the horizontal plane is 20-30 degrees;

[0052] A plurality of the second hot air pipes 6 are evenly arranged on the inner wall of the inlet channel 12, and the second hot air pipes 6 on the inlet channel 12 are all inclined. The hot air from the second hot air pipes 6 transports the desulfurized gypsum at the inlet channel 12 downstream, and at the same time dries and dehydrates the desulfurized gypsum.

[0053] By setting the inlet channel 12 to be inclined downward and the angle between the inlet channel 12 and the horizontal plane is 20-30 degrees, the desulfurized gypsum at the inlet channel 12 is mainly transported downstream by the hot air force of the second hot air pipe 6. In the process of transporting the desulfurized gypsum, the hot air contacts the desulfurized gypsum to dry and dehydrate the desulfurized gypsum.

[0054] In order to improve the feeding efficiency and not affect the drying effect of the desulfurized gypsum during the feeding process, a vertically arranged feeding pipe 13 is provided at the input end of the inlet channel 12, and a pushing block 14 is provided on one side of the bottom of the feeding pipe 13. The pushing block 14 is arranged on the opposite side of the inlet channel 12. The pushing block 14 is controlled by a hydraulic rod to approach or move away from the inlet channel 12. The desulfurized gypsum at the bottom of the feeding pipe 13 is pushed by the pushing block 14 to move to the end of the inlet channel 12, and then the hot air force of the second hot air pipe 6 transports the desulfurized gypsum at the inlet channel 12 downstream.

[0055] The desulfurized gypsum to be crushed is transported downward from the feed pipe 13. The desulfurized gypsum is easily accumulated at the bottom of the feed pipe 13. The push block 14 is pushed by the hydraulic rod to move the desulfurized gypsum at the bottom of the feed pipe 13 toward the inlet channel 12, thereby improving the feeding efficiency. When the desulfurized gypsum enters the end of the inlet channel 12, the hot air force of the second hot air pipe 6 is mainly used to transport the desulfurized gypsum at the inlet channel 12 downstream.

[0056] The pushing block 14 pushes the desulfurized gypsum into the inlet channel 12, but the desulfurized gypsum entering the inlet channel 12 is in a clustered state. Even if the desulfurized gypsum is moved by hot air, only part of the desulfurized gypsum can be dried. In order to further improve the drying effect of the desulfurized gypsum during the feeding process.

[0057] A rotating shaft 15 and a rotating plate 16 fixed on the outer surface of the rotating shaft 15 are provided between the inlet channel 12 and the feed pipe 13. The vertical section of the rotating plate 16 is arranged in an arc shape. The rotating plate 16 rotates with the rotation of the rotating shaft 15, thereby scooping up the desulfurized gypsum pushed to the end of the inlet channel 12 by the pushing block 14 and throwing it into the inlet channel 12, thereby transporting and dispersing the desulfurized gypsum.

[0058] The rotating shaft 15 is connected to an external motor. The rotation of the rotating shaft 15 drives the rotating plate 16 to rotate, thereby pushing the desulfurized gypsum pushed by the pushing block 14 to the end of the inlet channel 12, scooping up the desulfurized gypsum and throwing it into the inlet channel 12, thereby transporting and dispersing the desulfurized gypsum, increasing the contact area between the desulfurized gypsum and the hot air, and being beneficial to improving the drying and dehydration effect of the desulfurized gypsum during the feeding process.

[0059] Furthermore, the feed channel 5 also includes a feed discharge channel 17, which is arranged between the inlet channel 12 and the casing 1, and the feed discharge channel 17 is arranged to be inclined, and the angle between the feed discharge channel 17 and the horizontal plane is greater than the angle between the inlet channel 12 and the horizontal plane; the feed discharge channel 17 acts as a bridge between the inlet channel 12 and the casing 1, and compared with the drying and dehydration function of the inlet channel 12, its main function is feeding, but it also has a drying and dehydration effect.

[0060] A plurality of the second hot air pipes 6 are evenly arranged on the inner wall of the material discharge channel 17, and the second hot air pipes 6 on the material discharge channel 17 are all inclined;

[0061] A plurality of wire meshes 18 are provided inside the discharge channel 17. The desulfurized gypsum falling from the inlet channel 12 to the discharge channel 17 is dispersed multiple times after passing through the plurality of wire meshes 18. The hot air blown out from the second hot air pipe 6 accelerates the falling of the desulfurized gypsum while drying and dehydrating the desulfurized gypsum.

[0062] The desulfurized gypsum dehydrated by the inlet channel 12 is blown by the hot air in the second hot air duct 6 to the inside of the discharge channel 17. Since the discharge channel 17 has a large inclination angle, it mainly relies on the gravity of the desulfurized gypsum to fall into the casing 1. While the desulfurized gypsum falls, the second hot air duct 6 still blows hot air to dry and dehydrate the falling desulfurized gypsum, and the desulfurized gypsum is dispersed many times by the wire mesh 18 during the falling process, which increases the contact area between the hot air and the desulfurized gypsum, making the drying and dehydration effect better.

[0063] In order to further improve the drying effect of the desulfurized gypsum inside the feeding channel 17, the wire mesh 18 is fixedly connected to the feeding channel 17 by a spring 19, and the vertical section of the wire mesh 18 is set to be wavy to increase the contact area between the desulfurized gypsum and the wire mesh 18;

[0064] When the desulfurized gypsum falling from the inlet channel 12 passes through the wire mesh 18, it is dispersed by the wire mesh 18 and exerts a force on the wire mesh 18. The elastic force of the spring 19 causes the wire mesh 18 to continue to shake and disperse the desulfurized gypsum again.

[0065] By providing the spring 19, the wire mesh 18 can be continuously shaken, thereby improving the dispersion effect of the wire mesh 18 on the desulfurized gypsum, increasing the contact area between the hot air and the desulfurized gypsum, and achieving a better drying and dehydration effect.

[0066] The structure of the discharge channel 7 is further described below. Figure 4 As shown, a screen 20 is provided at the bottom of the casing 1, and the crushed desulfurized gypsum falls into the discharge channel 7 through the screen 20;

[0067] An inverted V-shaped dispersion cover 21 is provided inside the discharge channel 7, and a V-shaped flow guide cover 22 is provided at the bottom of the dispersion cover 21. Both sides of the flow guide cover 22 are connected to the inner wall of the discharge channel 7, and a discharge port 23 is provided in the middle of the flow guide cover 22.

[0068] The desulfurized gypsum that passes through the screen 20 and falls into the discharge channel 7 is evenly dispersed by the dispersion cover 21, and then collected by the guide cover 22 and discharged.

[0069] The crushed desulfurized gypsum falls from the screen 20 into the discharge channel 7, and the falling desulfurized gypsum first passes through the dispersion cover 21, which evenly disperses the desulfurized gypsum, thereby increasing the contact area between the desulfurized gypsum and the moving hot air in the discharge channel 7 and improving the dehydration effect of the crushed desulfurized gypsum. The desulfurized gypsum is then collected by the guide cover 22 and discharged.

[0070] Sealing plates 24 are hinged on both sides of the bottom of the discharge channel 7, and telescopic rods 25 are provided on both sides of the bottom of the discharge channel 7. In the initial state, the output end of the telescopic rod 25 is stretched, and the telescopic rod 25 applies a force to the sealing plate 24, so that the sealing plate 24 seals the discharge channel 7. When discharge is required, the output end of the telescopic rod 25 contracts, and the sealing plate 24 automatically rotates downward under the action of gravity, so that the desulfurized gypsum inside the discharge channel 7 is discharged.

[0071] The sealing plate 24 seals the discharge channel 7, which is conducive to forming a low-pressure area at the bottom of the discharge channel 7, facilitating the falling of the desulfurized gypsum and facilitating the circulation of hot air. When it is necessary to discharge the material, the sealing plate 24 can be opened.

[0072] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.

The elastic force of the spring (19) causes the wire mesh (18) to continue to shake, thereby dispersing the desulfurized gypsum again.

9. A dehydration hammer type dispersing machine according to claim 8, characterized in that: A screen (20) is provided at the bottom of the casing (1), and the crushed desulfurized gypsum passes through the screen (20) and falls into the discharge channel (7); An inverted V-shaped dispersion cover (21) is provided inside the discharge channel (7), and a V-shaped flow guide cover (22) is provided at the bottom of the dispersion cover (21), both sides of the flow guide cover (22) are connected to the inner wall of the discharge channel (7), and a discharge port (23) is provided in the middle of the flow guide cover (22); The desulfurized gypsum that passes through the screen (20) and falls into the discharge channel (7) is evenly dispersed through the dispersion cover (21), and then collected through the guide cover (22) and discharged.

10. A dehydration hammer type dispersing machine according to claim 9, characterized in that: Sealing plates (24) are hingedly connected to both sides of the bottom of the discharge channel (7). Telescopic rods (25) are provided on both sides of the bottom of the discharge channel (7). In an initial state, the output end of the telescopic rod (25) is stretched, and the telescopic rod (25) applies a force to the sealing plates (24), so that the sealing plates (24) seal the discharge channel (7). When discharge is required, the output end of the telescopic rod (25) is retracted, and the sealing plates (24) automatically rotate downward under the action of gravity, so that the desulfurized gypsum in the discharge channel (7) is discharged.
