Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer production equipment, specifically to a hammer-type raw material crushing device for fertilizer production. Background Technology

[0002] Chemical fertilizers are fertilizers containing nutrients needed for crop growth, produced using chemical and physical methods. They are an indispensable part of modern agriculture. Common raw materials include natural gas, coal, petroleum, and ore. After preliminary processing, these raw materials are sent to production equipment. In the process of fertilizer production, it is necessary to crush the raw materials to make them finer and easier to process in subsequent steps.

[0003] Existing fertilizer production raw material crushing devices lack a hammer-like effect during operation. For example, a fertilizer raw material crushing device disclosed in application number CN201410385441.8. Most existing fertilizer raw material crushing devices of this type use crushing wheels for crushing. During the crushing process, the shearing and compressive forces on the material may be uneven, resulting in uneven particle size distribution of the crushed fertilizer raw materials. This may affect the subsequent production quality and application effect of fertilizer. The initially crushed material falls directly into the interior or bottom of the device, preventing repeated crushing. Manual re-discharge and re-crushing are required, increasing labor intensity and the complexity of the crushing work. For fertilizer raw materials requiring ultrafine crushing, the crushing wheel may not achieve the desired crushing effect. Ultrafine crushing typically requires higher energy input and more precise crushing equipment. During prolonged operation, the direct contact and friction between the crushing wheel and the fertilizer raw material leads to rapid wear, increasing equipment maintenance costs and potentially affecting crushing efficiency and production effectiveness.

[0004] Therefore, it is necessary to invent a hammer-type raw material crushing device for fertilizer production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a hammer-type raw material crushing device for fertilizer production, so as to solve the problem that the device does not have a hammer-type effect when in use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hammer-type raw material crushing device for fertilizer production, comprising a large base, a pre-crushing frame, a preliminary crushing frame, and a feeding tray. The pre-crushing frame is arranged above one side of the large base, the preliminary crushing frame is arranged above the pre-crushing frame, and the feeding tray is arranged below the preliminary crushing frame. A connecting seat is arranged at the port of the feeding tray, and a hammer-type crushing tank is arranged on one side of the connecting seat. The hammer-type crushing tank is located on the other side of the large base, and a tank cover is arranged on the top of the hammer-type crushing tank. An air compressor is arranged in the middle of the top surface of the tank cover, and a feeding valve port is arranged on the lower side of one side of the outer wall of the hammer-type crushing tank.

[0007] Preferably, the preliminary crushing frame is hexagonal, one end of the preliminary crushing frame is equipped with a motor, and a detachable frame door is installed on one side of the surface of the preliminary crushing frame.

[0008] Preferably, the motor and the preliminary crushing frame are connected by a transmission, and the motor drives the preliminary crushing frame to rotate. The inner wall surface of the preliminary crushing frame is provided with protrusions.

[0009] Preferably, the interior of the connecting seat is hollow, the feeding tray is inclined, the end connection surface between the connecting seat and the feeding tray is open, and a feeding pipe is installed on the surface of the connecting seat and the hammering tank. The output end of the feeding pipe is inserted into the upper part of the inner wall of the hammering tank, and the end of the feeding pipe is located at the inner wall surface of the hammering tank.

[0010] Preferably, a small base is fixedly installed between the bottom of the hammering can and the large base, and a stable support is provided between the top surface of the small base and the body of the hammering can. The hammering can passes through the middle of the small base, and a placement groove matching the shape of the bottom of the hammering can is opened in the middle of the inner bottom surface of the small base. A rubber pad is placed in the middle of the placement groove.

[0011] Preferably, a hammer rod is connected below the output end of the air compressor, the hammer rod is located inside the hammer tank, and a hammer body is provided at the bottom end of the hammer rod.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] This hammer-type raw material crushing device for fertilizer production achieves efficient crushing of fertilizer raw materials through the dual crushing action of a preliminary crushing frame and a hammer impact tank. The preliminary crushing frame is driven by a motor to rotate, using the protrusions on its inner wall to initially impact and frictionally crush the raw materials. Subsequently, the raw materials enter the hammer impact tank, where they are further refined under the high-speed hammering of the hammers. The hammer impact can be repeated in a single cycle to ensure the crushing effect. This hammer-type raw material crushing device for fertilizer production is suitable for crushing various fertilizer raw materials. The hammer impact crusher has high production capacity, uniform products, and minimal over-crushing, meeting the particle size requirements of fertilizer production and improving subsequent processing efficiency. The hammer impact crusher impacts materials with a large crushing ratio and low energy consumption per unit product, effectively reducing production costs. It is also highly adaptable, suitable for various medium-hardness and brittle materials, and can adjust the crushing fineness to meet the crushing needs of different fertilizer raw materials.

[0024] The motor 301 and air compressor 8 mentioned above are existing technology products, and their specific structures and functions will not be described in detail here.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figures 1-5For this type of hammer-type raw material crushing device for fertilizer production, the raw material is first placed on the feed rack 2 and then enters the preliminary crushing frame 3. The preliminary crushing frame 3 is hexagonal and has protrusions 302 on its inner wall. The motor 301 drives the preliminary crushing frame 3 to rotate. The protrusions 302 perform preliminary impact and friction crushing on the raw material. The raw material after preliminary crushing slides down through the feed tray 4. The feed tray 4 is inclined to facilitate the natural slide of the raw material or manual intervention. The raw material enters the hammer tank 6 through the hollow part inside the connecting seat 5 and through the feed pipe 501. The air compressor 8 is installed on the top tank cover 7 of the hammer tank 6. The output end is connected to the hammer rod 801. When the air compressor 8 works, it generates compressed air, which drives the hammer rod 801 to reciprocate, thereby driving the hammer body 802 to hammer and crush the raw material in the hammer tank 6. The crushed raw material is discharged through the feed valve port 9 on the lower side of the outer wall of the hammer tank 6.

[0027] When using this device, check that all components are in good working order, including the motor 301, air compressor 8, hammer rod 801, and hammer 802. Clean the feed frame 2, preliminary crushing frame 3, and hammering tank 6 to ensure there are no foreign objects. Place the fertilizer raw material to be crushed on the feed frame 2. The raw material is initially crushed through the preliminary crushing frame 3. Start the motor 301 to drive the preliminary crushing frame 3 to rotate. Start the air compressor 8 to generate compressed air, which pushes the hammer rod 801 and hammer 802 to crush the material. During the operation of the equipment, monitor the crushing effect. If necessary, adjust the speed of the motor 301 or the pressure of the air compressor 8 to optimize the crushing effect. After crushing, discharge the crushed raw material through the discharge valve 9. Clean all components of the equipment to prepare for the next crushing.
