Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production equipment, and in particular to a gypsum feeding and dispersing device with high efficiency and stable operation. Background Art

[0002] In the production process of paper-faced gypsum board, after being conveyed by the transmission belt, the desulfurized gypsum will first enter the dispersing device filled with hot flue gas, start the one-step calcination, and complete the one-step calcination in the subsequent pipeline transportation and reamer transportation process to remove most of the attached water and a small amount of crystal water. Since the desulfurized gypsum raw materials are easy to clump during the storage and drying process, a dispersing device is required to fully break up these lumps and make them flow in the pipeline under the action of negative pressure. However, during the storage of the desulfurized gypsum raw materials, there are two ways of water flow, one is to escape into the air, and the other is to sink from high to low under the action of gravity. Therefore, there are two types of gypsum raw material agglomeration: dry agglomeration and wet agglomeration. The dry desulfurized gypsum raw materials can be directly output through negative pressure after being dispersed by the hammer, while the wet desulfurized gypsum raw materials will adhere to the hammer during the dispersing process. Long-term production will cause the hammer to stick, affecting the dispersing effect and causing material accumulation in the equipment.

[0003] At present, how to dry the wet agglomerates of desulfurized gypsum raw materials before breaking them up has become a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] The invention provides a gypsum feeding and dispersing device with high efficiency and stability, which is used to solve the problem of how to dry the wet agglomerates of desulfurized gypsum raw materials before dispersing them.

[0005] The present invention provides a gypsum feeding and dispersing device with high efficiency and stability, comprising:

[0006] A feeding pipeline, used for feeding desulfurized gypsum powder and desulfurized gypsum agglomerate mixture;

[0007] The agglomeration breaking device, the input end of which is connected to the output end of the feed pipeline, is used to break up the agglomerates of desulfurized gypsum;

[0008] The input end of the discharge pipe is connected to the output end of the agglomeration breaking device, and an exhaust fan is installed on the output end to output the desulfurized gypsum powder;

[0009] Wherein, a first electric heating device is installed on the inner wall of the feed pipe.

[0010] In some embodiments, a breaking hammer is provided on the upper inner side of the agglomeration breaking device, and a desulfurized gypsum powder discharge channel is provided on the bottom.

[0011] In some embodiments, the beating hammer head is a hammer-type hammer head.

[0012] In some embodiments, a screening mechanism is installed on the inner wall of the feed pipe for screening the desulfurized gypsum powder and the desulfurized gypsum agglomerate mixture, the desulfurized gypsum powder falls into the desulfurized gypsum powder discharge channel, and the desulfurized gypsum agglomerates fall onto the breaking hammer head.

[0013] In some embodiments, a partition is also provided in the agglomeration breaking device to prevent the desulfurized gypsum powder from falling onto the breaking hammer head.

[0014] In some embodiments, the feed pipe and the discharge pipe are both installed on a cement platform, the cement platform is installed on the ground through columns, and the agglomeration breaking device is installed on the ground through anchor bolts.

[0015] In some embodiments, a second electric heating device is provided inside the beating hammer head.

[0016] In some embodiments, a third electric heating device is provided on the inner wall of the discharge pipe.

[0017] In some embodiments, an observation structure is provided on the agglomeration deagglomeration device.

[0018] In some embodiments, a vibrator is installed on the discharge pipe.

[0019] The beneficial effects of the present invention are as follows: the gypsum feeding and breaking device of the present invention has high efficiency and stability in operation, and can first screen the desulfurized gypsum powder and the desulfurized gypsum agglomerate mixture entering the feed pipe by setting a screening mechanism, and dry it by a first electric heating device, and the desulfurized gypsum powder after screening falls into the desulfurized gypsum powder discharge channel, and is directly output through the discharge pipe under the action of the exhaust fan, and the desulfurized gypsum agglomerates separated by the screening mechanism will roll to the breaking hammer head, and after being broken up by the breaking hammer head, fall into the desulfurized gypsum powder discharge channel, and be output under the action of the exhaust fan. Compared with the traditional dispersing device, the technical solution of the present invention classifies the desulfurized gypsum powder and the desulfurized gypsum agglomerates, which reduces the load of the dispersing hammer and reduces the energy consumption. The desulfurized gypsum powder that does not need to be dispersed can be quickly output. In addition, in addition to the first electric heating device installed on the feed pipeline to dry the wet agglomerates, a second electric heating device is also installed inside the dispersing hammer, which can prevent the wet desulfurized gypsum raw materials from adhering to the hammer during the dispersing process. Therefore, the technical solution of the present invention gives the gypsum raw materials greater flowability, can effectively avoid the problem of material accumulation in the device, and stabilize production.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than 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.

[0026] At present, during the storage of desulfurized gypsum raw materials, there are two ways for water to flow: one is to escape into the air, and the other is to sink from high to low under the action of gravity. Therefore, there are two types of gypsum raw material agglomerates: dry agglomerates and wet agglomerates. At the same time, the original disintegration device uses a blade-type hammer head. Although it can also crush gypsum raw materials under high-speed rotation, the input of wet agglomerates will cause a small amount of them to adhere to the hammer head. Long-term production will cause the hammer head to stick, affecting the disintegration effect and causing material accumulation in the equipment; the blade-type hammer head crushing method focuses more on cutting and tearing, and its crushing efficiency is relatively low, especially when dealing with large or hard materials.

[0027] Therefore, how to dry the wet agglomerates of desulfurized gypsum raw materials before breaking them up and how to fully break them up has become a technical problem that needs to be solved urgently by those skilled in the art.

[0028] To solve the above problems, refer to Figure 1-Figure 4 The present invention provides a gypsum feeding and dispersing device with high efficiency and stability, comprising a feeding pipeline 1 for feeding desulfurized gypsum powder and desulfurized gypsum agglomerate mixture;

[0029] The agglomeration breaking device 2, whose input end is connected to the output end of the feed pipeline 1, is used to break up the agglomerates of desulfurized gypsum;

[0030] The input end of the discharge pipe 3 is connected to the output end of the agglomeration breaking device 2, and an exhaust fan 4 is installed on the output end for outputting the desulfurized gypsum powder;

[0031] Among them, a first electric heating device is installed on the inner wall of the feed pipe 1. The first electric heating device is a first electric heating rod 6, and the first electric heating rod 6 is arranged circumferentially along the inner wall of the feed pipe 1 to ensure that the desulfurized gypsum agglomerates entering the feed pipe 1 are heated evenly.

[0032] Preferably, a breaking hammer is provided on the upper side of the agglomeration breaking device 2, and a desulfurized gypsum powder discharge channel is provided at the bottom;

[0033] Specifically, the agglomeration breaking device 2 includes: a breaking device housing, a first breaking hammer 11, a second breaking hammer 12, a driving motor 13, a driving gear 14 and a driven gear 15; wherein the first breaking hammer 11 and the second breaking hammer 12 are both rotatably connected to the inside of the breaking device housing, the output end of the driving motor 13 is connected to the driving gear 14, the driving gear 14 is meshed with the driven gear 15, the driving gear 14 is connected to the second breaking hammer 12 through a rotating shaft, and the driven gear 15 is connected to the first breaking hammer 11 through a rotating shaft, and the surface of the first breaking hammer 11 and the second breaking hammer 12 is circumferentially connected with a plurality of hammer-type hammer heads, and the plurality of hammer-type hammer heads are distributed in multiple groups along the axial direction of the rotating shaft, so that the first breaking hammer 11 and the second breaking hammer 12 of the present invention can rotate relatively, and the hammer-type hammer heads on the first breaking hammer 11 and the second breaking hammer 12 are meshed with each other, with a large working area, high efficiency, no omissions, and the desulfurized gypsum agglomerates can be fully broken up.

[0034] Preferably, the breaking hammer is a hammer-type hammer, which can effectively avoid hammer head adhesion compared to a blade-type hammer. The hammer-type hammer has a larger mass, a larger rotation radius and a higher rotation speed, so the centrifugal force generated is larger. This larger centrifugal force helps the hammer to more effectively form a crushing effect such as striking, impacting and shearing the material. The material can be more fully crushed when struck, producing finer particles. The hammer-type hammer is more suitable for crushing materials with higher viscosity, thereby improving the crushing efficiency.

[0035] Preferably, a screening mechanism is installed on the inner wall of the feed pipe 1 for screening the mixture of desulfurized gypsum powder and desulfurized gypsum agglomerates, the desulfurized gypsum powder falls into the desulfurized gypsum powder discharge channel, and the desulfurized gypsum agglomerates fall onto the breaking hammer.

[0036] Specifically, the screening mechanism includes a support rod 7, a screen 8 and a first vibration motor 9. One end of the support rod 7 is installed on the inner wall of the feed pipe 1, and the other end is rotatably connected to one end of the screen 8. The first vibration motor 9 is installed on the inner wall of the feed pipe 1, and the output end of the first vibration motor 9 is connected to the other end of the screen 8. After the desulfurized gypsum powder and the desulfurized gypsum agglomerates enter from the feed pipe 1, they will fall onto the screen 8 under the action of gravity, and then be screened under the action of the first vibration motor 9. The desulfurized gypsum powder falls into the desulfurized gypsum powder discharge channel through the screen, and the desulfurized gypsum agglomerates will roll along the screen 8 to the first breaking hammer 11 and the second breaking hammer 12 for breaking.

[0037] Preferably, a partition is also provided in the shell of the breaking device, wherein a first partition 10 is installed on the inner wall of the feed pipe 1 on one side of the screen 8 to prevent the desulfurized gypsum powder from falling onto the first breaking hammer 11 and the second breaking hammer 12 to increase the load.

[0038] Specifically, a second vibration motor 17 is also installed at the inner bottom of the shell of the disintegration device, and the output end of the second vibration motor 17 is connected to one side of the inclined plate 18. The height of the inclined plate 18 close to the feed pipe 1 is higher than that of the other side, so that the desulfurized gypsum powder can accumulate at the bottom of the discharge pipe 3 under the action of its own gravity, which is convenient for discharging.

[0039] In addition, a second partition 19 is installed on the inner wall of the dispersing device shell on the left side of the first dispersing hammer 11, which is used to prevent the desulfurized gypsum lumps from rolling down to the bottom of the discharge pipe 3; a third partition 22 is obliquely installed on the inner wall of the dispersing device shell at the top of the second dispersing hammer 12, which is used to guide the desulfurized gypsum lumps to roll down to the meshing part of the first dispersing hammer 11 and the second dispersing hammer 12, and a fourth partition 23 is vertically installed on the inner wall of the dispersing device shell at the lower part of the rotating connection end of the support rod 7 and the screen 8, which is used to guide the desulfurized gypsum powder to fall onto the inclined plate 18.

[0040] Preferably, the feed pipe 1 and the discharge pipe 3 are both installed on a cement platform 5, the cement platform 5 is installed on the ground through columns, and the agglomeration breaking device 2 is installed on the ground through anchor bolts.

[0041] Preferably, a second electric heating device is provided inside the breaking up hammer head, and the second electric heating device is a second electric heating rod 16, and the first breaking up hammer 11 and the second breaking up hammer 12 are both circumferentially provided with a second electric heating rod 16, which is used to heat the hammer head to prevent wet lumps from adhering to the hammer head, affecting the breaking up effect and causing material accumulation in the equipment.

[0042] Preferably, a third electric heating device, i.e., a third electric heating rod 20, is provided on the inner wall of the discharge pipe 3. A plurality of third electric heating rods 20 are circumferentially arranged along the inner wall of the discharge pipe 3. A small amount of moisture may still exist inside the desulfurized gypsum powder after being dispersed by the agglomeration and disintegration device. Therefore, the third electric heating rod 20 is provided in the technical solution of the present invention to heat the desulfurized gypsum powder to be discharged and dry the moisture inside it.

[0043] Preferably, an observation structure is provided on the agglomeration breaking device 2. The observation structure of the technical solution of the present invention is an observation window 21 rotatably connected to the agglomeration breaking device 2, which is used to observe the internal working conditions of the device.

[0044] Preferably, a vibrator is installed on the discharge pipe 3 for vibrating the discharge pipe 3 to prevent the desulfurized gypsum powder still containing a small amount of moisture from adhering to the discharge pipe 3 .

[0045] In addition, in the technical solution of the present invention, the angle between the discharge pipe 3 and the horizontal direction is 70 degrees. Compared with the 60-degree angle of the prior art, the present invention increases the verticality of the inclined wall of the discharge pipe 3, greatly reduces the engineering workload, and reduces the footprint of the device.
