Description

Technical Field

[0001] The utility model belongs to the technical field of calcining furnaces, and in particular relates to a calcining furnace with an anti-blocking material structure. Background Art

[0002] A gypsum calcining furnace is a high-temperature furnace specifically used for calcining gypsum ore. It is mainly used to heat natural gypsum to a certain temperature to dehydrate it and convert it into various forms of gypsum powder such as anhydrous gypsum. The raw material for gypsum calcination is mainly blocky natural gypsum ore. During the feeding process, large pieces of gypsum ore may cause blockage of the feeding port, seriously affecting the stability and continuity of the feeding. At the same time, the blockage not only affects the production efficiency of gypsum, but may also cause equipment failure. The conventional solution is to crush the gypsum ore before feeding. This method can effectively reduce the volume of the gypsum ore. However, if the moisture content in the gypsum ore is high during the crushing process, it will cause stickiness during crushing. It is still impossible to completely rule out the sticky gypsum entering the calcining furnace and causing blockage. Once this sticky gypsum raw material blocks the pipeline, it will have a serious impact on the normal use of the calcining furnace. Therefore, a new structure is proposed to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a calcining furnace with an anti-blocking structure.

[0004] The utility model is realized by the following technical solution: a calcining furnace with an anti-blocking structure, comprising: a main body, a vibration ring and a sieve plate, a sieve cavity is provided inside the upper part of the main body, a fixed ring is provided below the sieve cavity, a vibration ring is provided above the fixed ring, and a sieve plate is provided on the top of the vibration ring;

[0005] Vibration rods are provided at the four corners of the top of the vibration ring, a vibration sleeve is sleeved on the outer side of the vibration rod, a vibration spring is fixed on the top of the vibration sleeve, a fixing block is provided on the top of the vibration sleeve, and a magnet is embedded in the top of the fixing block;

[0006] The sieve plate comprises a sieve and an outer frame. The inner side of the outer frame is glued and fixed to the outer side of the sieve. Iron blocks are embedded in the four corners of the bottom of the outer frame.

[0007] As a preferred embodiment, a box door is installed on the front of the screening chamber, a crushing chamber is provided above the screening chamber, a crushing mechanism is provided inside the crushing chamber, the bottom of the crushing chamber is connected to the top of the screening chamber, the box door is connected to the left side of the front of the main body through a hinge column, and the box door is sealed to the front of the screening chamber. The crushing mechanism inside the crushing chamber first crushes the gypsum ore. During the processing, since the gypsum ore contains moisture, it will become sticky. The volume of the processed gypsum raw material becomes smaller, which is more conducive to calcination.

[0008] As a preferred embodiment, a guide ring is welded above the inside of the screening cavity, and the bottom of the guide ring is directly above the screen plate. The guide ring is a trumpet-shaped structure with a diameter gradually increasing from bottom to top. The outer side of the guide ring is welded and fixed to the inner wall of the screening cavity. The guide ring changes the falling direction of the gypsum raw material so that the gypsum raw material is concentrated directly above the top of the screen and falls downward on the top of the screen, thereby facilitating the screening of the gypsum raw material.

[0009] As a preferred embodiment, the radius of the bottom of the guide ring matches the length of the screen, the screen is a square structure, and the aperture of the screen matches the diameter of the gypsum raw material particles.

[0010] As a preferred embodiment, the top of the vibration rod is located inside the vibration sleeve, a limit plate is provided on the top of the vibration rod, a limit slot is provided inside the vibration sleeve, and the radius of the limit plate matches the radius of the limit slot.

[0011] As a preferred embodiment, the top of the limit plate is fixed to the bottom of the vibration spring, the top of the vibration spring is fixed to the upper inside of the vibration sleeve, the length of the vibration rod matches the depth of the vibration sleeve, the vibration rod transmits the vibration upward to the limit plate, and repeatedly squeezes the vibration spring through the limit plate. At the same time, the natural frequency of the vibration spring matches the vibration frequency applied by the electromagnetic vibrator, so a resonance phenomenon is generated between the two, and then the vibration is amplified by the action of the vibration spring.

[0012] As a preferred embodiment, the outer side of the fixed ring is welded and fixed to the inner wall of the screening chamber, and a group of electromagnetic vibrators are respectively provided at the front and rear positions on the left and right sides of the top of the fixed ring. The bottom of the electromagnetic vibrator is glued and fixed to the top of the fixed ring, and the top of the electromagnetic vibrator is glued and fixed to the bottom of the vibration ring.

[0013] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: by setting a vibration rod, a vibration sleeve, a vibration spring and a screen plate, the bottom of the vibration rod is fixed to the top of the vibration ring, so that the vibration rod will vibrate up and down following the vibration ring, so that the top of the vibration rod vibrates repeatedly up and down inside the vibration sleeve, and the limit plate at the top of the vibration rod moves up and down along the limit groove and repeatedly squeezes the vibration spring, so that the vibration is amplified by the vibration spring, thereby increasing the vibration frequency of the screen plate. Therefore, when the gypsum raw material falls to the top of the screen, the sticky part of the gypsum raw material is retained on the top of the screen through repeated vibration, so that the gypsum raw material particles leak through the screen and go down into the main body for calcination, thereby preventing the sticky part of the gypsum raw material from entering the main body and causing blockage, ensuring the normal use of the calcining furnace, thereby improving the calcination efficiency, and at the same time, by setting a fixing block and an iron block, the screen plate can be easily installed and removed, which is convenient for maintenance and use.

[0026] See also Figures 1 to 6 A calcining furnace with an anti-blocking structure includes: a main body 100, a vibration ring 300 and a sieve plate 400. A sieve cavity is provided above the main body 100, a fixed ring 200 is provided below the sieve cavity, a vibration ring 300 is provided above the fixed ring 200, and a sieve plate 400 is provided on the top of the vibration ring 300;

[0027] Vibration rods 320 are provided at the four corners of the top of the vibration ring 300. A vibration sleeve 310 is sleeved on the outside of the vibration rod 320. A vibration spring 311 is fixed on the top of the vibration sleeve 310. A fixing block 330 is provided on the top of the vibration sleeve 310. A magnet is embedded in the top of the fixing block 330.

[0028] The sieve plate 400 includes a sieve 410 and an outer frame 420 . The inner side of the outer frame 420 is glued and fixed to the outer side of the sieve 410 . Iron blocks 421 are embedded in the four corners of the bottom of the outer frame 420 .

[0029] A box door 110 is installed on the front of the screening chamber, a crushing chamber is provided above the screening chamber, a crushing mechanism is provided inside the crushing chamber, the bottom of the crushing chamber is connected to the top of the screening chamber, the box door 110 is connected to the left side of the front of the main body 100 through a hinge column, and the box door 110 is sealed to the front of the screening chamber. The crushing mechanism inside the crushing chamber first crushes the gypsum ore. During the processing, since the gypsum ore contains moisture, it will become sticky. The volume of the processed gypsum raw material becomes smaller, so it is more conducive to calcination.

[0030] A guide ring 120 is welded above the inside of the screening cavity, and the bottom of the guide ring 120 is directly above the screen plate 400. The guide ring 120 is a trumpet-shaped structure with a diameter gradually increasing from bottom to top. The outer side of the guide ring 120 is welded and fixed to the inner wall of the screening cavity. The guide ring 120 changes the falling direction of the gypsum raw material, so that the gypsum raw material is concentrated directly above the top of the screen 410 and falls downward on the top of the screen 410, so that the gypsum raw material can be easily screened.

[0031] The radius of the bottom of the guide ring 120 matches the length of the screen 410. The screen 410 is a square structure, and the aperture of the screen 410 matches the diameter of the gypsum raw material particles.

[0032] The top of the vibration rod 320 is located inside the vibration sleeve 310. A limiting plate is provided on the top of the vibration rod 320. A limiting groove is provided inside the vibration sleeve 310. The radius of the limiting plate matches the radius of the limiting groove.

[0033] The top of the limiting plate is fixed to the bottom of the vibration spring 311, and the top of the vibration spring 311 is fixed to the upper inside of the vibration sleeve 310. The length of the vibration rod 320 matches the depth of the vibration sleeve 310. The vibration rod 320 transmits the vibration upward to the limiting plate, and repeatedly squeezes the vibration spring 311 through the limiting plate. At the same time, the natural frequency of the vibration spring 311 matches the vibration frequency applied by the electromagnetic vibrator 210, so a resonance phenomenon is generated between the two, and then the vibration is amplified by the action of the vibration spring 311.

[0034] The outer side of the fixed ring 200 is welded and fixed to the inner wall of the screening chamber. A group of electromagnetic vibrators 210 are respectively provided at the front and rear positions on the left and right sides of the top of the fixed ring 200. The bottom of the electromagnetic vibrator 210 is glued and fixed to the top of the fixed ring 200, and the top of the electromagnetic vibrator 210 is glued and fixed to the bottom of the vibration ring 300.

[0035] Example 1: Please refer to Figures 1 to 6, in actual use, the sieve plate 400 is in an installed state, and the iron blocks 421 embedded in the four corners of the bottom of the outer frame 420 are respectively opposite to the fixed blocks 330 on the top of the four groups of vibration sleeves 310. A magnet is embedded in the top of the fixed block 330, and the magnet material is neodymium iron boron magnet. Therefore, through the adsorption effect of the four groups of magnets and the four groups of iron blocks 421, the sieve plate 400 is stably adsorbed on the top of the vibration ring 300. The electromagnetic vibrators 210 installed at the four corners of the top of the fixed ring 200 are connected to the external power supply through wires. After the screening work starts, the four groups of electromagnetic vibrators 210 drive the vibration ring 300 to vibrate up and down (the electromagnetic vibrator 210 is a prior art, and its model can be selected according to the existing models on the market, and will not be repeated here). The vibration ring 300 drives the vibration rods 320 at the four corners of the top to vibrate up and down, so that the top of the vibration rod 320 vibrates up and down inside the vibration sleeve 310. At the same time, the vibration rod 320 The limiting plate at the top of 0 vibrates inside the limiting groove opened on the inner side of the vibration sleeve 310, which can prevent the top of the vibration rod 320 from falling off from the bottom of the vibration sleeve 310. At the same time, the limiting plate repeatedly squeezes the vibration spring 311 up and down following the up and down vibration of the vibration rod 320. Since the natural frequency of the vibration spring 311 matches the vibration frequency applied by the electromagnetic vibrator 210, there is a resonance phenomenon between the two, so that the vibration applied by the electromagnetic vibrator 210 is amplified by the four groups of vibration springs 311, and then the vibration of the sieve plate 400 at the top of the vibration ring 300 is amplified. The final effect is that the electromagnetic vibrator 210 provides vibration, the vibration rod 320 transmits the vibration to the vibration spring 311, and the vibration spring 311 transmits the amplified vibration to the sieve plate 400, thereby greatly increasing the screening efficiency of the sieve plate 400 and preventing sticky gypsum raw materials from entering the main body 100 and causing blockage, affecting the normal use of the main body 100.

[0036] Example 2: Please refer to Figure 2 、 Figure 5 and Figure 6 , when the gypsum raw material is crushed inside the crushing chamber (a crushing mechanism is provided inside the crushing chamber to crush the gypsum ore, and this process is prior art and will not be described in detail here), the gypsum raw material enters the screening chamber downwardly, and the gypsum raw material first falls on the inner side of the guide ring 120 on the top of the screen plate 400, and is changed in its falling direction by the guide ring 120 and then falls vertically on the top of the screen 410 inside the screen plate 400. Due to the vibration of the vibrating ring 300 and the vibration spring 311, the screen plate 400 vibrates up and down repeatedly, thereby driving the screen 410 to repeatedly screen the gypsum raw material up and down, and then the sticky part in the gypsum raw material is retained on the top of the screen 410. The screened gypsum raw material passes through the screen 410 and continues to fall downward, thereby greatly reducing the sticky part in the gypsum raw material from entering the interior of the main body 100, thereby greatly reducing the risk of the main body 100 being blocked;

[0037] After the main body 100 stops working, the box door 110 can be opened, and the front side of the sieve plate 400 can be held and lifted upward, so that the iron blocks 421 embedded in the four corners of the bottom of the outer frame 420 are respectively detached from the magnets embedded in the top of the four groups of fixed blocks 330, so that the sieve plate 400 can be taken out from the box door 110. Then the gypsum raw materials retained on the top of the sieve plate 400 can be reworked for secondary crushing, thereby saving gypsum raw materials and making the installation and disassembly of the sieve plate 400 simple, convenient for maintenance and cleaning.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
