Description

Technical Field

[0001] This utility model relates to the field of feeding mechanism technology, and in particular to a feeding mechanism for a normally closed drying kiln. Background Technology

[0002] A drying kiln is an industrial device used to remove moisture from materials, and it is widely used in industries such as ceramics, wood, building materials, chemicals, and food. Its core function is to achieve rapid and uniform drying of materials by controlling parameters such as temperature, humidity, and airflow, thereby ensuring product quality.

[0003] Currently, in order to prevent heat loss from the inside of the drying kiln through the feed inlet, the feed inlet is sealed after feeding is completed. Most existing feed inlets are sealed by setting a sealing cover. However, the sealing cover design is not easy to operate. The staff needs to install and remove the sealing cover every time they feed material. The operation is cumbersome and can easily cause burns.

[0004] Therefore, this application proposes a feeding mechanism for a normally closed drying kiln. Utility Model Content

[0005] This utility model discloses a feeding mechanism for a normally closed drying kiln, which aims to solve the technical problem of inconvenient operation of existing feeding mechanisms due to their sealed working conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding mechanism for a normally closed drying kiln includes an installation cylinder and a feeding port. A feeding pipe is embedded on the lower surface of the feeding port and is slidably connected to the inside of the installation cylinder. A shaking mechanism is provided between the feeding pipe and the installation cylinder, and a sealing mechanism is provided inside the feeding port.

[0008] The sealing mechanism includes two symmetrical sealing plates rotatably connected to the inner walls on both sides of the feed inlet via a rotating shaft. Arc-shaped sliding holes are provided through both sides of the feed inlet. Arc-shaped support rods are fixedly connected to the lower surface of the sealing plates through the arc-shaped sliding holes. A limit plate is fixedly connected to one end of the arc-shaped support rod extending out of the feed inlet surface. A spring is sleeved on the surface of the arc-shaped support rod inside the feed inlet.

[0009] In a preferred embodiment, the shaking mechanism includes a transmission groove formed on the inner right side of the mounting cylinder. A mounting bracket is fixedly mounted on the right side surface of the feed pipe through the transmission groove. A roller is rotatably connected between the mounting bracket and the feed pipe via a connecting rod. A motor is fixedly mounted on the right side surface of the mounting cylinder. The output shaft of the motor extends into the interior of the transmission groove and is fixedly connected to an eccentric transmission block, and the eccentric transmission block corresponds to the position of the roller.

[0010] By using an eccentric transmission block and rollers, the feed inlet can be vibrated up and down by the feed pipe.

[0011] In a preferred embodiment, two symmetrical guide sliders are provided on both sides of the feed tube, and guide grooves for the guide sliders to slide are provided on both sides of the inner wall of the mounting cylinder.

[0012] By setting a guide slider, the feed pipe can move smoothly up and down within the mounting cylinder under the guidance of the guide slider.

[0013] In a preferred embodiment, the mounting cylinder has mounting slots on both the front and back sides. A hot air blower is fixedly mounted on the back side of the feed pipe through the mounting slots. A ventilation cavity is provided inside the housing on the rear side of the feed pipe. An air outlet is provided on the inner wall of the ventilation cavity, extending into the feed pipe. The air outlet of the hot air blower is connected to the interior of the ventilation cavity. An exhaust vent is provided on the front side of the feed pipe, and a filter screen is provided on the inner wall of the exhaust vent.

[0014] By using a hot air blower, the materials conveyed in the feed pipe can be dried.

[0015] In a preferred embodiment, the number of air outlets is several, and the several air outlets are equidistantly opened on the inner wall of the ventilation cavity.

[0016] In a preferred embodiment, the surface of the mounting cylinder is fixedly connected to a mounting edging, and the surface of the mounting edging is provided with a plurality of threaded holes, the inner wall of which is threaded with mounting bolts.

[0017] The installation of the edging and mounting bolts facilitates the assembly of the feeding mechanism with the external drying kiln.

[0018] As can be seen from the above, the feeding mechanism of the normally closed drying kiln provided by this utility model has the following technical effects.

[0019] Firstly, when using this feeding mechanism for material feeding, the material is directly poured into the feed inlet. Under the weight of the material, the sealing plate is pushed downwards and flipped, allowing the material to enter the drying kiln through the feed inlet and feed pipe, thus completing the feeding process. After the material is empty, the sealing plate is pushed upwards and reset under the action of the spring, sealing the feed inlet. The operation is simple, avoiding the need for manual loading and unloading of the sealing cover while also avoiding the risk of burns.

[0020] Secondly, the operation of the motor drives the eccentric transmission block to rotate. After the rotation of the eccentric transmission block comes into contact with the roller, the roller drives the feed pipe to move upward. By repeating this process, the feed pipe can be made to vibrate up and down, which can prevent the material from adsorbing and clogging the feed pipe wall. At the same time, the operation of the hot air blows hot air into the ventilation cavity and into the feed pipe through several air outlets. Under the action of hot air, the material flowing in the feed pipe can be preliminarily dried, removing some of the moisture from the material and making the feeding smoother.

A shaking mechanism is provided between the feed pipe 3 and the installation cylinder 1. A sealing mechanism is provided inside the feed inlet 2.

[0031] The sealing mechanism includes two symmetrical sealing plates 4 rotatably connected to the inner walls on both sides of the feed inlet 2 via a rotating shaft. Arc-shaped sliding holes are opened through both sides of the feed inlet 2. Arc-shaped support rods 5 are fixedly connected to the lower surface of the sealing plates 4 through the arc-shaped sliding holes. A limit plate 6 is fixedly connected to one end of the arc-shaped support rods 5 extending out of the surface of the feed inlet 2. A spring 7 is sleeved on the surface of the arc-shaped support rods 5 inside the feed inlet 2.

[0032] The surface of the mounting cylinder 1 is fixedly connected with a mounting edging. The surface of the mounting edging is provided with several threaded holes, and the inner wall of the threaded holes is threaded with mounting bolts 17. The mounting edging and mounting bolts 17 facilitate the assembly of the feeding mechanism with the external drying kiln.

[0033] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the shaking mechanism includes a transmission groove formed on the inner wall of the right side of the mounting cylinder 1. A mounting bracket 8 is fixedly mounted on the right side surface of the feed pipe 3 through the transmission groove. A roller 9 is rotatably connected between the mounting bracket 8 and the feed pipe 3 through a connecting rod. A motor 10 is fixedly mounted on the right side surface of the mounting cylinder 1. The output shaft of the motor 10 extends into the interior of the transmission groove and is fixedly connected to an eccentric transmission block 11. The eccentric transmission block 11 corresponds to the position of the roller 9.

[0034] By setting up the eccentric transmission block 11 and the roller 9, the feed inlet 2 can be driven to vibrate up and down through the feed pipe 3.

[0035] Two symmetrical guide sliders 12 are provided on both sides of the feed pipe 3. Guide grooves for sliding of the guide sliders 12 are provided on both sides of the inner wall of the mounting cylinder 1. Under the guidance of the guide sliders 12, the feed pipe 3 can move smoothly up and down in the mounting cylinder 1.

[0036] Reference Figure 5 , Figure 6 and Figure 7In a preferred embodiment, the front and back of the mounting cylinder 1 are provided with mounting slots. A hot air blower 13 is fixedly mounted on the back of the feed pipe 3 through the mounting slots. A ventilation cavity 14 is provided inside the housing on the rear side of the feed pipe 3. An air outlet 15 is provided on the inner wall of the ventilation cavity 14, which extends into the feed pipe 3. The air outlet of the hot air blower 13 is connected to the interior of the ventilation cavity 14. An exhaust micro-port is provided on the front of the feed pipe 3. A filter screen 16 is provided on the inner wall of the exhaust micro-port. With the hot air blower 13, the material conveyed in the feed pipe 3 can be dried.

[0037] There are several air outlets 15, which are equidistantly arranged on the inner wall of the ventilation cavity 14.

[0038] Working principle: When using this feeding mechanism for material feeding, the material is directly poured into the feed inlet 2. Under the weight of the material, the sealing plate 4 is pushed downwards, allowing the material to enter the drying kiln through the feed inlet 2 and the feed pipe 3, thus completing the feeding process. After the material is empty, the sealing plate 4 is pushed upwards and reset under the action of the spring 7, sealing the feed inlet 2. During this period, the operation of the motor 10 drives the eccentric transmission block 11 to rotate. After the rotation of the eccentric transmission block 11 contacts the roller 9, the roller 9 drives the feed pipe 3 to move upwards. This reciprocating motion makes the feed pipe 3 vibrate up and down, preventing the material from adsorbing and clogging the wall of the feed pipe 3. At the same time, the operation of the hot air blower 13 blows hot air into the ventilation chamber 14 and into the feed pipe 3 through several air outlets 15. Under the action of the hot air, the material flowing in the feed pipe 3 can be preliminarily dried, removing some of the moisture and making the feeding smoother.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
