Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a pulverizer with dustproof function. Background Technology

[0002] A crusher is a common piece of equipment used to crush materials from larger particles into smaller particles or powder. For dust control, high-efficiency dust collection devices are installed at the discharge port of the crusher and in areas prone to dust generation. These devices can capture and collect the generated dust in a timely manner, preventing it from spreading into the air and causing air pollution. If the dust is inhaled by nearby operators, it can affect their health.

[0003] Existing pulverizers are equipped with efficient dust collection devices at the discharge port or in areas prone to dust generation to capture and store the dust in a timely manner. However, these devices need to be cleaned regularly to prevent excessive dust from causing blockages. Most pulverizers perform a single pulverization operation on the raw materials. In the process of developing this application, the inventors discovered the following problems with the existing technology: Although the dust collector can effectively prevent dust, it requires regular cleaning, which is cumbersome. A pulverizer that only performs a single pulverization operation on the raw materials may result in incomplete pulverization and may even affect its pulverization efficiency.

[0004] Therefore, those skilled in the art have provided a pulverizer with dustproof function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dustproof pulverizer that can perform secondary pulverization of raw materials, resulting in finer and more thorough pulverization. While the pulverizer is operating, the suction fan will quickly absorb the generated dust and directly transfer it into the collection box, thus eliminating the need for regular cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof pulverizer, comprising a machine body, a collection box fixedly installed at the lower end of the machine body, a pulverizing chamber opened inside the machine body, a feed inlet opened at the upper end of the machine body, two inclined baffles fixedly installed at the upper end of the pulverizing chamber, and two No. 1 pulverizing gears and No. 2 pulverizing gears rotatably installed at the lower end of the pulverizing chamber, with the two No. 1 pulverizing gears located between the baffles and the two No. 2 pulverizing gears.

[0007] Furthermore, the No. 1 crushing gear and the No. 2 crushing gear on one side of the machine body are connected in pairs through pulleys and belts, and the two No. 2 crushing gears on the other side of the machine body are connected to motors.

[0008] Furthermore, a transmission pipe is fixedly installed between the crushing chamber and the collection box near the baffle. A suction fan is fixedly installed inside the upper end of the transmission pipe, and a filter screen is fixedly installed near the port of the transmission pipe near the suction fan. An insertion hole is fixedly provided on one side of the machine body near the transmission pipe, and the insertion hole is electrically connected to the suction fan.

[0009] Furthermore, the collection box has two discharge ports at its lower end, and a valve is fixedly installed on one side of each discharge port.

[0010] Furthermore, each of the two discharge ports has two nuts threaded to its lower end, and each of the two nuts is fixedly connected to a cloth bag.

[0011] This utility model has the following beneficial effects:

[0012] 1. The present invention proposes a dustproof pulverizer. When the raw material is placed into the pulverizing chamber, it is first pre-pulverized by two No. 1 pulverizing gears, and then further pulverized into powder by two No. 2 pulverizing gears. This improves the pulverizing efficiency of the pulverizer and makes the raw material pulverized more thoroughly. An embedded suction fan is fixed at the upper end of the pulverizing chamber, which can absorb the dust that is blown out to a certain extent. The absorbed dust will be directly sent into the collection box, so there is no need to clean it regularly.

[0013] 2. The present invention proposes a dustproof pulverizer. The pulverized raw material in the collection box will enter the cloth bag through two discharge ports. The nuts fixed on the cloth bag can be threadedly connected to the discharge ports to make it more stable, so that it will not fall due to the increased weight of the cloth bag. The dust generated when the pulverized raw material is discharged from the discharge port will not leak out, thus achieving a dustproof effect at the discharge port. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 One embodiment provided by this utility model:

[0022] A dustproof pulverizer includes a body 1, a collection box 17 fixedly installed at the lower end of the body 1, a pulverizing chamber 10 inside the body 1, a feed inlet 13 at the upper end of the body 1, two inclined baffles 9 fixedly installed at the upper end of the pulverizing chamber 10, and two first pulverizing gears 11 and two second pulverizing gears 12 rotatably installed at the lower end of the pulverizing chamber 10. The two first pulverizing gears 11 are located between the baffles 9 and the two second pulverizing gears 12. The first pulverizing gears 11 and the second pulverizing gears 12 on one side of the outer side of the body 1 are connected in pairs by pulleys 4 and belts, and are located on the other side of the outer side of the body 1. Both No. 2 crushing gears 12 are connected to motors 3. A transmission pipe 2 is fixedly installed between the crushing chamber 10 and the collection box 17 near the baffle 9. A suction fan 14 is fixedly installed inside the upper end of the transmission pipe 2, and a filter screen 16 is fixedly installed at the port of the transmission pipe 2 near the suction fan 14. An insertion hole 15 is fixedly installed on one side of the machine body 1 near the transmission pipe 2. The insertion hole 15 is electrically connected to the suction fan 14. Two discharge ports 6 are opened at the lower end of the collection box 17. A valve 5 is fixedly installed on one side of the two discharge ports 6. Two nuts 7 are threaded to the lower end of each of the two discharge ports 6. A cloth bag 8 is fixedly connected to each of the two nuts 7.

[0023] Specifically, the collection box 17 can collect the crushed raw materials. The raw materials are put in through the feed inlet 13 and slide into the crushing chamber 10 through two inclined baffles 9, falling onto the two first crushing gears 11 for pre-crushing. The pre-crushed raw materials then fall between the two second crushing gears 12 for secondary crushing. After being crushed into powder, they fall into the collection box 17. The two motors 3 can start and drive the two second crushing gears 12 to rotate respectively. The first crushing gear 11 and the second crushing gear 12 on the outside of the machine body 1 are connected by a pulley 4 and a belt. The two gears are connected in pairs. When the two No. 2 crushing gears 12 rotate, they can drive the two No. 1 crushing gears 11 to rotate together. The dust that is blown out during the crushing process will be absorbed by the suction fan 14 into the transmission pipe 2 and then fall directly into the collection box 17. The filter screen 16 at the upper end of the transmission pipe 2 can prevent raw material fragments from entering the suction fan 14 and affecting the operation of the suction fan 14. The two valves 5 can control the opening and closing status of the two discharge ports 6 respectively. The cloth bag 8 is fixed with a nut 7 that can be threadedly connected to the discharge port 6. The cloth bag 8 is used to load the crushed raw materials.

[0024] Working Principle: Raw materials are fed into the crushing chamber 10 through the feed inlet 13 for crushing. The materials fall through two inclined baffles 9 into the two primary crushing gears 11. As the materials fall, they are blocked by the filter 16 at the suction fan 14, preventing material fragments from entering and damaging the suction fan 14. The suction fan 14 is embedded and does not obstruct the normal fall of the materials. The two motors 3 start, driving the two secondary crushing gears 12 to rotate. Since the primary crushing gears 11 and 12 on the outer side of the machine body 1 are connected in pairs by pulleys 4 and belts, the rotation of the two secondary crushing gears 12 drives the two primary crushing gears 11 to rotate together. The materials are first crushed by the two primary crushing gears 11, and then fall between the two secondary crushing gears 12 for secondary crushing, resulting in more thorough crushing. The powdered material falls into the collection box 17. Dust generated during the crushing process is dispersed towards the dust collector. The dust rises from the top of the crushing chamber 10 and is collected to a certain extent by the built-in suction fan 14 to prevent most of the dust from leaking out. The absorbed dust will fall directly into the collection box 17 through the transmission pipe 2, thus eliminating the need to clean the dust in the transmission pipe 2 regularly. The socket 15 is used to connect the power supply to start the suction fan 14. The powdered raw materials collected in the collection box 17 will fall directly into the two cloth bags 8 through the two discharge ports 6, effectively preventing the dust generated when the crushed raw materials are released from the discharge ports 6 from leaking out. The valves 5 on the two discharge ports 6 can control the two discharge ports 6 separately. The valve 5 opens one discharge port 6 to receive the finished raw materials into the cloth bag 8. After it is full, the valve 5 closes the discharge port 6. Then, the other valve 5 opens the other discharge port 6 to continue receiving the finished raw materials into the cloth bag 8. The cloth bag 8 is fixed with a nut 7 and threadedly connected to the discharge port 6 to increase stability and prevent the cloth bag 8 from falling easily when the weight of the finished raw materials increases slowly.

[0025] Secondly, when using the machine, the raw material is fed into the crushing chamber 10 through the feed inlet 13 and then the two motors 3 are started. The raw material in the crushing chamber 10 is first pre-crushed by the two first crushing gears 11. When the dust generated during the crushing process floats out after bypassing the baffle 9, it is sucked into the transmission pipe 2 by the suction fan 14 to a certain extent. The absorbed dust will directly enter the collection box 17 through the transmission pipe 2, so there is no need to clean it regularly. The pre-crushed raw material falls between the two second crushing gears 12 and is crushed again, which can improve the crushing efficiency of the crusher. The cloth bag 8 is tightened on the discharge port 6 by the nut 7. The opening and closing status of the two discharge ports 6 can be controlled by the valve 5. After the raw material is crushed, it falls into the collection box 17 and then falls into the cloth bag 8 through the two discharge ports 6 in turn.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
