Description

Technical Field

[0001] The utility model belongs to the technical field of calcium hydrogen phosphate preparation equipment, and particularly relates to a crusher cyclone dust removal device. Background Art

[0002] Fertilizer-grade calcium hydrogen phosphate, commonly known as white phosphate fertilizer or white fertilizer, is a byproduct of feed-grade calcium hydrogen phosphate production. It is a white, monoclinic, crystalline powder that is odorless and tasteless. It typically exists as a dihydrate with the chemical formula CaHPO4·2H2O. It is stable in air and begins to lose its water of crystallization upon heating to 75°C, becoming an anhydrate. At higher temperatures, it converts to pyrophosphate.

[0003] The production of calcium hydrogen phosphate requires that its raw materials be crushed first to meet the requirements for the normal operation of subsequent equipment. When the raw materials are crushed, a large amount of dust will be generated. At the same time, a small amount of small stones will be splashed. If the generated dust is not collected and treated, it will affect the working environment of the production area and is not conducive to the physical and mental health of the workers. In addition, the small stones splashed during the crushing also need to be protected. Otherwise, they will injure the staff and bring certain safety hazards to production.

[0004] Chinese patent application number CN2023222898280 discloses a crushing and dust removal device for the production of calcium hydrogen phosphate. The square frame is fixedly mounted on the right side plate of the crusher. The protective cover consists of a U-shaped top plate and two side plates. The protective cover is hinged to the left side end of the square frame through a rotating shaft at the upper right end of the top plate. A door curtain is fixedly mounted on the left end of the top plate of the protective cover. The protective cover is placed on the crusher through the two side plates. The door curtain is suspended above the feed end of the crusher. The purification tank is located at the side end of the crusher. The partition separates the purification tank into a sedimentation chamber and a clean water chamber. An overflow port is provided on the partition. The sedimentation chamber and the clean water chamber are connected to each other through the overflow port.

[0005] As the applicant conducted further research, it was found that although this technical solution can control all the dust or small stones generated during the operation of the crusher in the protective cover, thereby preventing flying stones from injuring the workers, the dust removal components of this technical solution are limited by their own structure. The dust removal components and the frame cannot be disassembled and need to be loaded and unloaded as a whole, which increases the transportation cost. When the cyclone dust collector needs to be transferred and transported to other places for use, the loading work intensity is high. Utility Model Content

[0036] like Figure 1 - Figure 7 As shown, a crusher cyclone dust removal device of the present invention includes a support frame, a housing 2, an exhaust pipe 3, a crusher 6, and a fan assembly 4;

[0037] The outer shell 2 is cylindrical and connected to the support frame. The outer shell 2 has an inlet end 20 opened on the side and an outlet end 21 on the top.

[0038] The exhaust pipe 3 is coaxially arranged in the housing 2;

[0039] The fan assembly 4 is connected to the top of the housing 2 and communicates with the exhaust pipe 3;

[0040] The support frame includes a frame body 10, an upper support leg 11 and a lower support leg 12. The upper support leg 11 and the lower support leg 12 are detachably connected.

[0041] The mechanism of the cyclone dust removal device used in this scheme is to make the dust-laden airflow rotate, and use centrifugal force to separate the crushed dust from the airflow and capture it on the inner wall of the conical shell, and then use gravity to make the dust fall into the ash storage hopper.

[0042] A square frame 7 is installed on the upper side of the crusher 6, and an air duct 8 is provided between the crusher 6 and the housing 2. The two ends of the air duct 8 are respectively connected to the inlet end 20 and the square frame 7;

[0043] The square frame 7 is hinged with a protective cover 9 , which is U-shaped and can be flipped from the upper part of the square frame 7 to be arranged at the feed position of the crusher 6 .

[0044] By attaching the protective cover 9 to the crusher 6 via two side panels 93, with the door curtain 92 suspended above the feed end of the crusher 6, and the protective cover 9 being hinged to the square frame 7 via a rotating shaft at the upper right end of the top plate 90, dust and small stones generated during the operation of the crusher 6 are controlled within the protective cover 9, which not only protects the environment but also prevents flying stones from injuring workers. When the crusher 6 needs to be repaired, the protective cover 9 can be flipped backward, making it very convenient to inspect and maintain the crusher 6.

[0045] Specifically, the protective cover 9 includes a top plate 90 and side plates 93 located on both sides of the top plate 90 , and a door curtain 92 is connected below the end of the top plate 90 .

[0046] The above-mentioned protective cover 9 and square frame 7 are both existing technologies. The specific structure and connection form can refer to the technical solutions mentioned in the background technology. The above-mentioned structure does not fall within the scope of protection of this application.

[0047] The technical solution of this embodiment adopts a detachable support frame. When the device needs to be transported and loaded and unloaded, the lower leg 12 of the support frame is removed relative to the upper leg 11 and other upper components, which reduces the space occupied by the cyclone dust removal device, facilitates the loading and unloading operations of the device, and reduces transportation costs.

[0048] Specifically, the lower leg 12 is hollow, and the lower leg 12 is sleeved on the outer periphery of the upper leg 11, and the two are slidably connected.

[0049] The outer wall of the upper supporting leg 11 is symmetrically provided with a guide groove 111 along the axial direction, and the inner wall of the lower supporting leg 12 is provided with a ridge 120 matched with the guide groove 111 along the axial direction.

[0050] The ridge 120 slides relative to the guide groove 111, so that the lower leg 12 is separated from the upper leg 11, and the lower leg 12 and other parts can be placed together in the transport vehicle after disassembly and transferred to the next construction site, reducing the occupied space.

[0051] When the entire device is lifted by a crane, the ridge 120 cooperates with the guide groove 111, so that the upper leg 11 and the lower leg 12 are relatively smooth during separation. At the same time, the symmetrically arranged guide grooves 111 prevent the upper leg 11 and the lower leg 12 from rotating relative to each other, thereby increasing stability.

[0052] In addition, a stop ring 110 is provided on the outer periphery of the upper leg 11. This stop ring 110 allows the upper leg 11 to be relatively close to the lower leg 12, preventing them from moving when the two legs are aligned. The cross-section of the stop ring 110 is larger than that of the upper leg 11 and the lower leg 12, preventing further vertical movement once the legs are aligned.

[0053] The depth of the guide groove 111 in this embodiment is not less than 2 cm.

[0054] The bottom of the housing 2 in the cyclone device is conical. An ash hopper 5 is provided below the housing 2. When a certain amount of dust particles are transferred, the handle 50 provided on the ash hopper 5 is pulled to remove the ash hopper 5 for dumping.

[0055] Dust enters the housing 2 from the inlet end 20, wherein the housing 2 has an outer vortex guide vane, which rotates downward under the centrifugal force of its fan assembly 4. Large particles of impurities enter the ash storage hopper 5, and clean air rotates upward along the exhaust pipe 3 and is discharged through the outlet end 21.

[0056] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
