Description

Technical Field

[0001] This application relates to the technical field of calcium hydroxide production, and specifically discloses a crushing and dust collection device for calcium hydroxide production. Background Art

[0002] Calcium hydroxide, commonly known as slaked lime or hydrated lime, is a white powdery solid. After adding water, it is divided into two layers, the upper aqueous solution is called clarified lime water, and the lower suspension is called lime milk or lime slurry. The upper clear liquid, clarified lime water, can be used to test carbon dioxide, and the lower turbid liquid, lime milk, is a building material.

[0003] There are two production processes for manufacturing calcium hydroxide, namely the dry process and the wet process. The processes are slightly different, but the principles are the same. The dry production process requires crushing qualified quicklime raw materials to about 40 mm using existing crushers such as jaw crushers. However, when the existing crushing device crushes quicklime, a large amount of dust is easily generated. The dust is lifted from the feed inlet of the crusher and scattered everywhere in the production workshop, polluting the surrounding environment of the production workshop and posing a threat to the physical health of workers, damaging the workers' bodies. Therefore, in view of this, the inventor provides a crushing and dust collection device for calcium hydroxide production to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to solve the problem that a large amount of dust is generated during the crushing process of traditional calcium hydroxide, and the dust is lifted from the feed inlet of the crusher and scattered into the external environment, which is likely to damage the bodies of workers.

[0005] To achieve the above purpose, the basic solution of the present utility model provides a crushing and dust collection device for calcium hydroxide production, including a dust exhaust pipe communicated with the side of the feed inlet of the crusher, a support bottom plate for supporting the dust exhaust pipe, and a dust exhaust mechanism provided at one end of the dust exhaust pipe away from the crusher. A dust filter screen is provided in the dust exhaust pipe. An exhaust air pipe is communicated at one end of the dust exhaust pipe away from the crusher. A support box located below the dust filter screen is provided between one end of the support bottom plate and the bottom of the dust exhaust pipe. A support frame is provided between the other end of the support bottom plate and the bottom of the exhaust air pipe. The dust exhaust mechanism includes an exhaust air fan detachably installed in the exhaust air pipe and an installation box installed on the exhaust air pipe and detachably connected to the top of the support frame. A dust removal mechanism for removing the dust on the surface of the dust filter screen is provided between the bottom end of the dust exhaust pipe and the support box.

[0006] The principle and effect of this basic solution are as follows:

[0007] 1. By respectively providing a support box and a support frame at both ends of the support bottom plate, the present utility model not only provides structural support for the dust exhaust pipe and the exhaust air pipe respectively, but also maintains the balance of the overall structure at the same time, improving the stability of the overall structure.

[0008] 2. Compared with the prior art, the utility model is provided with a dust exhaust pipe communicating with the side of the feed inlet of the crusher, and at the same time, an exhaust air pipe and an exhaust air fan are provided. The dust in the air is gathered and attracted into the dust exhaust pipe at the open port of the crusher, so that all the dust is sucked into the dust exhaust pipe. By arranging a dust filter net in the dust exhaust pipe, the air passing through the dust exhaust pipe is filtered for dust, thereby greatly reducing the dust in the exhausted air, improving the air quality of the production workshop environment of calcium hydroxide, providing a safe working environment for workers, and solving the problem that traditional calcium hydroxide generates more dust during crushing treatment, the dust is raised from the feed inlet of the crusher and diffuses into the external environment, which is likely to cause damage to the workers' bodies.

[0009] 3. Compared with the prior art, the utility model is provided with a dust removal mechanism, which is convenient for removing the dust blocked on the surface of the dust filter net, preventing the dust from blocking on the surface of the dust filter net, thus slowing down the ventilation speed of the dust filter net, and avoiding the negative impact on the dust exhaust and exhaust air speeds of the crusher.

[0010] Furthermore, a conversion chamber is communicatively provided between the bottom of the dust exhaust pipe and the top of the support box. The dust removal mechanism includes a conversion arc plate rotatably connected to the inner side wall of the conversion chamber and used for blocking between the dust exhaust pipe and the conversion chamber, a support rod provided on the outer side of the conversion arc plate, a dust removal motor installed at the end of the support rod, and a dust removal brush rotatably connected to the end of the support rod and capable of brushing on the surface of the dust filter net. One end of the dust removal brush is coaxially connected to the output end of the dust removal motor. The inner diameter of the conversion arc plate is equal to the inner diameter of the dust exhaust pipe. The inner cavity of the conversion chamber is provided with a receiving groove with an inner diameter not less than that of the conversion arc plate. The conversion arc plate can rotate in the receiving groove and the dust exhaust pipe. A conversion motor for driving the conversion arc plate to rotate in the conversion chamber is installed on the outside of the conversion chamber. An adjusting mechanism for driving the dust removal motor to move telescopically along the support rod is provided at the end of the support rod. By setting the conversion motor to drive the conversion arc plate to rotate in the receiving groove of the conversion chamber, and setting the inner diameter of the conversion arc plate to be equal to the inner diameter of the dust exhaust pipe, and at the same time, structures such as a support rod, a dust removal motor, a dust removal brush, and an adjusting mechanism are provided on the outer side of the conversion arc plate, it is convenient to realize the space partition between the dust exhaust pipe and the support box when the open end of the conversion arc plate faces the dust exhaust pipe, facilitating the normal operation of the dust exhaust work. At the same time, when the open end of the conversion arc plate faces the support box, by operating the dust removal motor, the dust removal brush can be rotated and brushed on the surface of the dust filter net, so as to achieve the purpose of removing the dust on the surface of the dust filter net, enabling the support box to not only play a role in supporting the dust exhaust pipe, but also accommodate and collect the dust removed from the dust filter net by the dust removal brush. By removing the dust on the dust filter net, the blockage of the dust filter net is avoided, thus ensuring the continuous dust exhaust work of the dust exhaust pipe when the crusher crushes the calcium hydroxide raw material. By adjusting the height of the dust removal motor relative to the support rod through the adjusting mechanism, it is avoided that the dust removal motor and the dust removal brush extend too far relative to the support rod and affect the rotational movement of the conversion arc plate, making the positions of the dust removal motor and the dust removal brush adjustable, convenient to use, and more practical.

[0011] Furthermore, the support frame includes a support base detachably installed on the top surface of the end of the support bottom plate away from the support box, a plurality of support columns symmetrically and evenly provided on the top surface of the support base, and a support top plate provided at the top of the support columns. The installation box is detachably installed and connected to the support top plate. By setting the support base, the support columns, and the support top plate, it is convenient to install and fix the exhaust pipe and the fan to the installation box, thereby improving the stability of the structure.

[0012] Furthermore, the adjusting mechanism includes an electric telescopic rod provided at the end of the support rod and a controller for electrically connecting and controlling the movement of the electric telescopic rod. The dust removal motor is detachably installed at the end of the electric telescopic rod. By setting the controller to drive the electric telescopic rod to perform telescopic movement, the height of the dust removal motor and the dust removal brush relative to the support rod is adjusted, making the structure of the dust removal mechanism more compatible with the installation of the dust exhaust pipe, and more practical and flexible.

[0013] Furthermore, a mounting seat is provided at the end of the electric telescopic rod. The dust removal motor is detachably connected to the mounting seat, and one end of the dust removal brush is rotatably connected to the side of the mounting seat. By providing the mounting seat, it is convenient for the installation and fixation of the dust removal motor and the dust removal brush, making the structure of the dust removal mechanism more stable.

[0014] Furthermore, a mounting plate is provided on the outer side of the conversion arc plate, and the support rod is vertically fixed on the surface of the mounting plate. By providing the mounting plate, it is convenient for the installation of the support rod on the conversion arc plate, making the structure more stable. Description of the Drawings

As Figure 2 and Figure 3 shown, a receiving groove 14 with an inner diameter not less than that of the conversion arc plate 10 is arranged in the inner cavity of the conversion chamber 9. The conversion arc plate 10 can rotate in the receiving groove 14 and in the dust exhaust pipe 1. As Figure 4 shown, a conversion motor 15 for driving the conversion arc plate 10 to rotate in the conversion chamber 9 is installed on the outside of the conversion chamber 9.

[0024] Among them, as Figure 4 shown, the support frame 6 includes a support base 16 detachably installed on the top surface of one end of the support bottom plate 2 away from the support box 5, four support columns 17 evenly and symmetrically arranged on the top surface of the support base 16, and a support top plate 18 arranged at the top of the support columns 17.

[0026] Among them, as Figure 4As shown, a mounting seat 20 is provided at the end of the electric telescopic rod 19.

[0027] In the specific implementation process of the present invention, when the crusher is crushing calcium hydroxide raw materials, a large amount of dust is easily raised at the open feed port of the crusher. Therefore, while the crusher is powered on and running, the exhaust fan also needs to be turned on to discharge air from the side of the feed port of the crusher into the inlet end of the dust removal pipe 1 and discharge it from the outlet end of the exhaust pipe 4. At this time, the open end of the conversion arc plate 10 faces upward and forms a complete pipe structure with the inner diameter structure of the dust removal pipe 1. During this process, a large amount of dust raised at the feed port of the crusher is discharged into the dust removal pipe 1, and the dust in the air is blocked and filtered on the front end face of the dust filter screen 3. The air after dust filtration is discharged through the exhaust pipe 4, realizing the dust removal treatment of the air environment in the crusher and the calcium hydroxide production workshop. Whenever the crusher stops working and the dust filter screen 3 needs to be dusted, the conversion motor 15 is powered on to adjust the conversion arc plate 10 to rotate 180 degrees, so that the dust removal brush 13 faces upward and the open end of the conversion arc plate 10 faces downward. Then, the controller controls the electric telescopic rod 19 to extend and adjusts the output shaft of the dust removal motor 12 to coincide with the central axis of the dust removal pipe 1. Finally, the dust removal motor 12 is powered on, and the dust removal motor 12 drives the dust removal brush 13 to rotate. The dust removal brush 13 rotates and brushes on the surface of the dust filter screen 3, brushing the dust on the surface of the dust filter screen 3 onto the conversion arc plate 10 below it. When the dust removal is completed, the controller controls the electric telescopic rod 19 to retract, and then the conversion motor 15 drives the conversion arc plate 10 to rotate 180 degrees again, so that the open end of the conversion arc plate 10 faces downward. During this process, the dust on the conversion arc plate 10 falls into the support box 5 below the conversion chamber 9 and accumulates due to gravity and the rotational movement of the conversion arc plate 10. Finally, the worker takes out the dust in the support box 5 for reuse or other purposes.

[0028] Compared with the prior art, the utility model is provided with a dust exhaust pipe 1 communicating with the side of the feed inlet of the crusher, and at the same time, a ventilation pipe 4 and a ventilation fan are provided. Dust is gathered and attracted into the dust exhaust pipe 1 at the open port of the crusher, so that all the dust is sucked into the dust exhaust pipe 1. By arranging a dust filter screen 3 in the dust exhaust pipe 1, the air passing through the dust exhaust pipe 1 is filtered for dust, thereby greatly reducing the dust in the exhausted air, improving the air quality of the production workshop of calcium hydroxide, providing a safe working environment for workers, and solving the problem that a large amount of dust is generated during the crushing process of traditional calcium hydroxide. The dust rises from the feed inlet of the crusher and drifts into the external environment, which is likely to cause damage to the bodies of workers.

[0029] Compared with the prior art, the utility model is provided with a dust removal mechanism including a conversion arc plate 10, a support rod 11, a dust removal motor 12 and a dust removal brush 13, and an adjustment mechanism including an electric telescopic rod 19 and a controller, which is convenient for removing the dust blocked on the surface of the dust filter screen 3, preventing the dust from blocking on the surface of the dust filter screen 3, thus slowing down the ventilation speed of the dust filter screen 3, and avoiding the negative impact on the dust exhaust and ventilation speeds of the crusher.
