Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer raw material processing, and particularly relates to a cyclone dust removal device for processing calcium hydrogen phosphate. Background Art

[0002] The price of feed-grade phosphate in the market is affected by the phosphorus content of the product. Generally, the higher the phosphorus content, the higher the price. Therefore, it is critical to choose a suitable drying system to ensure the quality of the product.

[0003] In the existing feed-grade calcium hydrogen phosphate production, its drying mainly adopts airflow drying, spray drying and other methods. Since the heat source in the drying process is generally selected to be directly heated after coal combustion, ash will be introduced during the drying process.

[0004] Chinese patent application number CN201210081333.2 discloses a low-temperature drying method for feed-grade calcium hydrogen phosphate, in which feed-grade calcium hydrogen phosphate is uniformly fed into a microwave heater by a conveyor belt for drying. At the same time, an exhaust system is started to discharge the gas in the microwave equipment through a cyclone dust collector.

[0005] The cyclone dust collector uses a rotating mechanism to separate dust from the dust-laden airflow, trapping it on the wall through centrifugal force. Gravity then forces the dust down into the dust hopper. The main components of a cyclone dust collector include an inlet pipe, an exhaust pipe, a cylinder, a cone, a dust removal device, and a dust hopper.

[0006] For example, a Chinese patent with application number CN202021342720.3 discloses a cyclone dust removal device, including a frame; a cyclone dust collector body, the cyclone dust collector body is arranged on the frame; a bag sleeve, the upper opening of the bag sleeve is connected to the discharge port of the cyclone dust collector body; and an ash collecting part, the ash collecting part is arranged on the frame, and its upper opening is connected to the lower opening of the bag sleeve.

[0007] As the applicant conducted further research, it was found that the cyclone dust collector of this technical solution could not be disassembled and assembled due to its own structural limitations. In particular, the cyclone dust collector needed to be transported to other places for use. Since the cyclone dust collector body and the frame could not be disassembled, they had to be assembled and unassembled as a whole, which increased the transportation cost and the loading workload, causing inconvenience to the operators. Utility Model Content

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A cyclone dust removal device for calcium hydrogen phosphate processing, comprising:

[0010] Support frame;

[0011] The outer shell is cylindrical and connected to the support frame, and has an inlet end opened at the side and an outlet end opened at the top;

[0012] an exhaust pipe coaxially disposed in the housing;

[0013] a fan assembly connected to the top of the housing and in communication with the exhaust pipe;

[0014] The support frame includes a frame body, an upper support leg and a lower support leg, and the upper support leg and the lower support leg are detachably connected.

[0015] Furthermore, the lower leg is hollow, and the lower leg is sleeved on the outer periphery of the upper leg, and the two are slidably connected.

[0016] Furthermore, a limiting ring is provided on the outer periphery of the upper leg.

[0017] Furthermore, the outer wall of the upper leg is provided with guide grooves symmetrically along the axial direction.

[0018] Furthermore, the depth of the guide groove is not less than 2CM.

[0019] Furthermore, the inner wall of the lower leg is provided with a ridge along the axial direction.

[0020] Furthermore, the bottom of the shell is conical.

[0021] Furthermore, an ash storage hopper is provided below the shell.

[0022] Furthermore, a handle is provided on the ash storage hopper.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] A detachable support frame is used. When the device needs to be transported and loaded and unloaded, the lower support leg of the support frame is removed relative to the upper support leg 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.

[0025] When the entire device is lifted by a crane, the ridges cooperate with the guide grooves, making the upper and lower legs smoother during separation. At the same time, the symmetrically arranged guide grooves prevent the upper and lower legs from rotating relative to each other, thereby increasing stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1 - Figure 7As shown, a cyclone dust removal device for calcium hydrogen phosphate processing of the present invention includes a support frame, a shell 2, an exhaust pipe 3 and a fan assembly 4;

[0038] 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.

[0039] The exhaust pipe 3 is coaxially arranged in the housing 2;

[0040] The fan assembly 4 is connected to the top of the housing 2 and communicates with the exhaust pipe 3;

[0041] 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.

[0042] A detachable support frame is used. When the device needs to be transported and loaded and unloaded, the lower support leg 12 of the support frame is removed relative to the upper support leg 11 and other upper components, which reduces the space occupied by the cyclone dust collector, facilitates the loading and unloading operations of the device, and reduces transportation costs.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] The depth of the guide groove 111 in this embodiment is not less than 2 cm.

[0049] 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.

[0050] The flue gas enters the outer shell 2 from the inlet end 20, wherein the outer shell 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 the clean air rotates upward along the exhaust pipe 3 and is discharged through the outlet end 21.

[0051] 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.
