Description

Technical Field

[0001] This utility model relates to the field of ferrite material technology, specifically to a powder drying oven for ferrite material production. Background Technology

[0002] Ferrites are a new type of non-metallic magnetic material. Ferrites are generally composite oxides of iron and one or more other suitable metallic elements, belonging to the semiconductor family, and are utilized as magnetic media.

[0003] A search revealed a utility model patent with publication number CN218065689U, which discloses a powder drying box for the production of soft magnetic ferrite materials that is easy to clean. The box includes a body with a drying chamber fixed to its inner bottom wall. The body has a feed pipe extending through its left side wall at one end, and a discharge pipe fixed to its bottom surface. The drying chamber has a transmission mechanism inside, and the body has a heating mechanism inside. Simultaneously, the heating element is activated, heating the drying chamber via a rotating tube and a heat transfer liquid. After the heating chamber is heated, it heats the powder raw material. After the heating element is activated, the motor starts, driving a drive gear through a rotating rod. The drive gear, through a driven gear, drives the transmission tube to rotate. As the rotating tube rotates, the heating chamber rotates around it, simultaneously heating and drying the powder raw material while also stirring it. This ensures the powder raw material is dried evenly and thoroughly, achieving a rapid drying effect.

[0004] Although the aforementioned patent describes how the heating chamber rotates around the rotating tube while heating and drying the powdered raw materials, thereby achieving uniform and thorough drying and rapid drying, the problem is that the powdered raw materials are all piled together. While the rotating tube can stir the raw materials, it cannot break up large clumps of raw materials that are stuck together with water. This results in poor drying effect and uneven drying of the clumps of raw materials.

[0005] Therefore, it is necessary to propose a powder drying oven for ferrite material production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a powder drying box for ferrite material production. Through the cooperation between the internal parts of the stirring mechanism, the rake claws and spiral blades can stir and disperse the raw materials inside the drying tray, breaking up the clumps of raw materials. This solves the problem in the prior art that the drying box cannot disperse large pieces of raw materials that are stuck together by water, resulting in poor drying effect and uneven drying of the clumps of raw materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a powder drying oven for ferrite material production, comprising a drying oven body, a heater bolted to the inner wall of the drying oven body, a stirring mechanism slidably connected inside the drying oven body and located above the heater, and heat preservation mechanisms connected to both sides of the outer wall of the drying oven body and extending into the interior of the drying oven body;

[0008] The stirring mechanism includes multiple drying trays, which are fixedly connected to each other by electric telescopic rod bolts and slidably connected to the inner wall of the drying chamber body, and located above the heater. Sliding rods are slidably connected to both sides of the inner wall of the drying chamber body, and support rods are mechanically fixed between the sliding rods and located above the drying trays. The outer wall of the support rods is machined with symmetrically distributed spiral blades that penetrate into the inner cavity of the drying trays. Multiple rake claws are spirally distributed on the outer wall of the spiral blades.

[0009] The heat preservation mechanism includes an air outlet pipe, which is welded and fixed to both sides of the outer wall of the drying oven body and extends into the interior of the drying oven body. A drain pipe is sealed and connected to the lower part of the air outlet pipe and communicates with the inner wall of the air outlet pipe. A sealing partition is rotatably connected between the air outlet pipe and the inner wall of the drying oven body via a hinge. A connecting gear is mechanically sleeved on the outer wall of the sliding rod. A supporting rack is mechanically machined at the top left side of the drying tray and is located below the connecting gear.

[0010] Preferably, the stirring mechanism further includes multiple drive motors, which are bolted to the back of the drying chamber body. The output end of each drive motor is connected to a reciprocating screw via a coupling and extends into the interior of the drying chamber body. The sliding rod is rotatably connected to a reciprocating slide block on the side away from the support rod and is slidably connected to the interior of the drying chamber body, and is threadedly engaged with the outer wall of the reciprocating screw.

[0011] Preferably, the bottom of the drying chamber body is provided with an air inlet that matches the warm air blower, the bottom of the multiple drying trays is provided with dense ventilation holes, and the inner walls of the drying chamber body are provided with sliding grooves that match the sliding rods.

[0012] Preferably, the inner cavity at the top of the drying tray is provided with a movable groove that matches the support rod, and the spiral blades and rake claws are spirally distributed on the outer wall of the support rod, and the outer wall of the rake claws fits into the inner cavity of the drying tray.

[0013] Preferably, the connecting gear meshes with the supporting rack through a tooth groove, and the connection between the air outlet pipe and the inner wall of the drying chamber body is provided with a movable groove that matches the sealing partition. The diameter of the sealing partition is larger than the diameter of the air outlet pipe, and a drainage groove that matches the drain pipe is left between the sealing partition and the air outlet pipe.

[0014] Preferably, the inner cavity depth of the drying tray is 40mm, the inner wall of the drying chamber body is provided with a sliding groove that matches the reciprocating slide, and the inner wall of the reciprocating slide is equipped with a slide rod that matches the reciprocating thread on the outer wall of the reciprocating screw.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By pouring the raw materials to be dried into the drying trays, and stacking and fixing multiple drying trays together inside the drying chamber using electric telescopic rods and bolts, the drying trays are pushed upward by the electric telescopic rods to engage with the outer wall of the support rod, so that the spiral blades and rake claws fit into the inner cavity of the drying tray. The drive motor is started, and the drive motor drives the reciprocating screw to rotate. The rotation of the reciprocating screw drives the reciprocating slide to slide through the thread. The sliding of the reciprocating slide drives the sliding rod to move. The movement of the sliding rod drives the support rod to slide back and forth in the inner cavity of the drying tray, which drives the spiral blades and rake claws to stir and turn the raw materials in the drying tray. At the same time, the warm air blower heats the air inside the drying chamber, thus completing the drying of the raw materials in the drying tray.

[0017] The sliding rod moves above the drying tray by the reciprocating sliding block, causing the connecting gear fixed to the outer wall of the sliding rod to slide. The connecting gear meshes with the support rack at the top of the drying tray, thereby driving the sliding rod to rotate. The rotation of the sliding rod drives the support rod to rotate, and the rotation of the support rod drives the spiral blades and rake claws to rotate. This allows the spiral blades and rake claws to break up the clumps of raw materials, thereby improving the drying quality of the raw materials in the drying tray. Attached Figure Description

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 The powder drying box for ferrite material production shown includes a drying box body 1. A heater 101 is bolted to the inner wall of the drying box body 1. A stirring mechanism 2 is slidably connected inside the drying box body 1 and is located above the heater 101. Insulation mechanisms 3 are connected to both sides of the outer wall of the drying box body 1 and penetrate into the interior of the drying box body 1.

[0029] The stirring mechanism 2 includes multiple drying trays 201, which are fixedly connected to each other by electric telescopic rod bolts and slidably connected to the inner wall of the drying chamber body 1, and located above the heater 101. Sliding rods 203 are slidably connected to both sides of the inner wall of the drying chamber body 1, and support rods 202 are mechanically fixed between the sliding rods 203 and located above the drying trays 201. The outer wall of the support rods 202 is machined with symmetrically distributed spiral blades 204, which penetrate into the inner cavity of the drying trays 201. Multiple rake claws 205 are spirally distributed on the outer wall of the spiral blades 204.

[0030] The heat preservation mechanism 3 includes an air outlet pipe 301, which is welded and fixed to both sides of the outer wall of the drying oven body 1 and extends into the interior of the drying oven body 1. A drain pipe 302 is sealed and connected to the lower part of the air outlet pipe 301 and communicates with the inner wall of the air outlet pipe 301. A sealing partition 303 is rotatably connected between the air outlet pipe 301 and the inner wall of the drying oven body 1 via a hinge. A connecting gear 304 is mechanically sleeved on the outer wall of the sliding rod 203. A support rack 305 is machined on the top left side of the drying tray 201 and is located below the connecting gear 304.

[0031] Through the cooperation of the internal parts of the stirring mechanism 2, the rake claw 205 and the spiral blade 204 can stir and disperse the raw materials inside the drying tray 201, breaking up the clumps of raw materials. Through the cooperation of the internal parts of the heat preservation mechanism 3, the drying temperature inside the drying chamber 1 can be maintained, thereby improving the drying effect of the drying chamber 1.

[0032] Refer to the instruction manual appendix Figure 1-6 The stirring mechanism 2 also includes multiple drive motors 206, which are bolted to the back of the drying chamber body 1. The output end of the drive motor 206 is connected to a reciprocating screw 207 via a coupling and extends into the interior of the drying chamber body 1. The sliding rod 203 is rotatably connected to a reciprocating slide block 208 on the side away from the support rod 202 and is slidably connected to the interior of the drying chamber body 1. It is threadedly engaged with the outer wall of the reciprocating screw 207. Through the mutual cooperation between the internal components of the stirring mechanism 2, the reciprocating slide block 208 can drive the sliding rod 203 to slide back and forth.

[0033] Refer to the instruction manual appendix Figure 1-6 The bottom of the drying chamber body 1 is provided with an air inlet that matches the heater 101, and the bottom of the multiple drying trays 201 is provided with dense ventilation holes. The inner walls of the drying chamber body 1 are provided with sliding grooves that match the sliding rod 203. The air inlet at the bottom of the drying chamber body 1 that matches the heater 101 and the dense ventilation holes at the bottom of the multiple drying trays 201 facilitate the flow of hot air at the bottom of the drying trays 201 to dry the raw materials inside the drying trays 201.

[0034] Refer to the instruction manual appendix Figure 1-6 The inner cavity at the top of the drying tray 201 is provided with a movable groove that matches the support rod 202. The spiral blades 204 and rake claws 205 are spirally distributed on the outer wall of the support rod 202, and the outer wall of the rake claws 205 is in contact with the inner cavity of the drying tray 201. The spiral blades 204 and rake claws 205 are spirally distributed on the outer wall of the support rod 202, and the outer wall of the rake claws 205 is in contact with the inner cavity of the drying tray 201, which facilitates the rotation of the spiral blades 204 to stir the raw material dust in the inner cavity of the drying tray 201, while the rake claws 205 break up the raw materials that are stuck together.

[0035] Refer to the instruction manual appendix Figure 1-6The connecting gear 304 meshes with the supporting rack 305 through a tooth groove. A movable groove matching the sealing partition 303 is provided at the connection between the air outlet pipe 301 and the inner wall of the drying chamber body 1. The diameter of the sealing partition 303 is larger than the diameter of the air outlet pipe 301. A drainage groove matching the drain pipe 302 is provided between the sealing partition 303 and the air outlet pipe 301. This facilitates the rotation of the sealing partition 303 within the air outlet pipe 301 and the drying chamber body 1, forming a one-way valve structure between the sealing partition 303 and the drying chamber body 1.

[0036] Refer to the instruction manual appendix Figure 1-6 The inner cavity depth of the drying tray 201 is 40mm. The inner wall of the drying chamber body 1 is provided with a sliding groove that matches the reciprocating slide 208. The inner wall of the reciprocating slide 208 is equipped with a slide rod that matches the reciprocating thread on the outer wall of the reciprocating screw 207. The inner cavity depth of the drying tray 201 is 40mm, which helps to prevent the raw materials from being pushed too thickly, resulting in uneven drying of the raw materials.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-6 The raw materials to be dried are poured into the drying trays 201, and multiple drying trays 201 are stacked and fixed inside the drying chamber body 1 by electric telescopic rods and bolts. The electric telescopic rods push the drying trays 201 upward to engage with the outer wall of the support rod 202, so that the spiral blades 204 and rake claws 205 fit into the inner cavity of the drying trays 201. The drive motor 206 is started, and the drive motor 206 drives the reciprocating screw 207 to rotate. The rotation of the reciprocating screw 207 drives the reciprocating slide 208 to slide through the thread. The sliding of the reciprocating slide 208 drives the sliding rod 203 to move. The movement of the sliding rod 203 drives the support rod 202 to slide back and forth in the inner cavity of the drying trays 201. This drives the spiral blades 204 and rake claws 205 to stir and turn the raw materials in the drying trays 201. At the same time, the warm air blower 101 heats the air inside the drying chamber body 1, thus completing the drying of the raw materials in the drying trays 201.

[0039] Refer to the instruction manual appendix Figure 1-6The sliding rod 203 moves above the drying tray 201 via the reciprocating sliding block 208, causing the connecting gear 304, which is fixed to the outer wall of the sliding rod 203, to slide. This causes the connecting gear 304 to mesh with the support rack 305 at the top of the drying tray 201, thus rotating the sliding rod 203. The rotation of the sliding rod 203 then rotates the support rod 202, which in turn rotates the spiral blades 204 and rake claws 205. This allows the spiral blades 204 and rake claws 205 to break up any clumps of raw materials, improving the drying quality within the drying tray 201. Hot air rises, carrying moisture generated during drying, and flows through the drying chamber body 1 to the exhaust pipe 301. Simultaneously, the moisture in the exhaust pipe 301... After internal cooling, condensate is formed and discharged from the drain pipe 302. A movable groove matching the sealing partition 303 is provided at the connection between the air outlet pipe 301 and the inner wall of the drying chamber body 1. The diameter of the sealing partition 303 is larger than the diameter of the air outlet pipe 301. A drainage groove matching the drain pipe 302 is left between the sealing partition 303 and the air outlet pipe 301, which facilitates the rotation of the sealing partition 303 inside the air outlet pipe 301 and the drying chamber body 1. This forms a one-way valve structure between the sealing partition 303 and the drying chamber body 1, allowing the sealing partition 303 to rotate and open towards the air outlet pipe 301 under the push of air, but not towards the inner wall of the drying chamber body 1. Therefore, the internal temperature of the drying chamber body 1 is kept stable.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
