Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to an activated carbon screening device. Background Technique

[0002] As a commonly used adsorbent, activated carbon plays a very important role in many fields such as medicine, environmental protection, and chemical industry. From the perspective of the preparation process of activated carbon, considering the quality standards of activated carbon products, the functions of particle sorting and powder impurity removal possessed by vibrating screens are necessary for it. In addition, from the perspective of the adsorption application of activated carbon, an important factor affecting the adsorption effect of carbon on dissolved gold and silver is the quality of activated carbon. To improve the quality of activated carbon, in addition to strengthening the adjustment of carbon concentration, strictly controlling the particle size of carbon is also an important task. Therefore, activated carbon needs to be pretreated before use and strictly screened after treatment.

[0003] However, the existing screening devices have certain drawbacks. When the screening device conducts screening, the screened materials will pile up together, resulting in easy blockage during screening and inconvenient discharging. Secondly, when the existing screening mechanism discharges materials, it cannot drive vibration screening simultaneously, which has certain drawbacks. Therefore, there is an urgent need for an activated carbon screening device to solve the above problems. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides an activated carbon screening device, which is realized through the following technical solutions.

[0005] An activated carbon screening device includes a screening box. One end of the top of the screening box is provided with a feeding channel.

One end of the screening frame is rotatably connected inside the screening box, and the other end of the screening frame is fixedly supported in the first discharging channel through a spring. The cam rotates inside the screening box through a first shaft rod, and a second gear is fixedly connected to one end of the camshaft rod passing through the screening box. The power mechanism is used to drive the second gear to rotate.

[0010] Further, a screening opening is formed at the top of the screening frame. A screen is fixedly connected inside the screening opening. Two baffles fixed to the top of the screening frame are symmetrically distributed on both sides of the screen.

[0011] Further, the conveying mechanism includes a conveying roller and a conveyor belt. The conveying roller rotates inside the screening box through a second shaft rod provided, and there are two conveying rollers. The conveyor belt is arranged on the two conveying rollers. The second shaft rod on the right conveying roller penetrates through the screening box and is fixedly connected with a first gear and a first pulley. The power mechanism is used to drive the first pulley to rotate, and the first gear is meshed with a second gear.

[0012] Further, the power mechanism includes a motor. The motor is fixedly connected to one side of the screening box. The output shaft of the motor is fixedly connected with a second pulley. The second pulley drives the first pulley to rotate synchronously through a transmission belt provided.

[0013] The beneficial effect of the present utility model is that during the working process of the device, first, the power mechanism provided drives the screening mechanism and the conveying mechanism to operate simultaneously.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figures 1-5 shown, the present utility model has the following specific embodiments.

[0029] Embodiment:

[0030] An activated carbon screening device includes a screening box 1. One end of the top of the screening box 1 is provided with a feeding channel 11. The guide plate 14 fixed inside the screening box 1 is located below the feeding port of the feeding channel 11. The two sides of the screening box 1 are respectively provided with a first discharge channel 12 and a second discharge channel 13. It further includes:

[0031] A screening mechanism for screening materials;

[0032] A conveying mechanism for conveying the fine materials after screening;

[0033] A power mechanism for driving the screening mechanism and the conveying mechanism to operate synchronously.

[0034] By adopting the above technical solution, when using the device, first, the power mechanism drives the screening mechanism and the conveying mechanism to operate simultaneously. Then, the activated carbon is input into the screening box 1 through the feeding channel 11. The guide plate 14 can guide and convey the activated carbon onto the screening rack 2. The operating screening rack 2 can vibrate and screen the activated carbon. The coarsely screened materials are output through the first discharge channel 12, and the finely screened materials fall onto the conveying mechanism and are output through the second discharge channel 13, which facilitates the simultaneous screening and discharging of materials and avoids the accumulation of materials after screening.

[0035] Specifically, the screening mechanism includes a screening rack 2 and a cam 5. The right end of the screening rack 2 is inclined downward by 15° and connected inside the screening box 1. One end of the screening rack 2 is rotatably connected inside the screening box 1, and the other end of the screening rack 2 is fixedly supported in the first discharge channel 12 through a spring 24 provided. The cam 5 rotates inside the screening box 1 through a first shaft rod. The shaft rod of the cam 5 penetrates through one end of the screening box 1 and is fixedly connected with a second gear 51. The power mechanism is used to drive the second gear 51 to rotate.

[0036] A screening opening 21 is formed at the top of the screening rack 2. A screen 22 is fixedly connected inside the screening opening 21. Two baffles 23 fixed to the top of the screening rack 2 are symmetrically distributed on both sides of the screen 22.

[0037] By adopting the above technical solution, the power mechanism can drive the screening rack 2 to vibrate inside the screening box 1, that is, the power mechanism can drive the second gear 51 to rotate. The second gear 51 drives the connected cam 5 to rotate through the first shaft rod. The rotating cam 5 can intermittently press the screening rack 2. Since one end of the screening rack 2 under pressure is supported and connected to the first discharge channel 12 through the spring 24, and the other end of the screening rack 2 is rotatably connected to the screening box 1, it can drive the screening rack 2 to vibrate inside the screening box 1. The vibrating screening rack 2 can improve the screening effect of materials and at the same time facilitate the automatic sliding and output of the coarsely screened materials.

[0038] Among them, since the screen 22 is fixed in the screening opening 21 formed in the screening rack 2, the vibrating screening rack 2 drives the screen 22 to screen the materials. The two baffles 23 fixed to the screening rack 2 can block the materials and prevent them from falling from the side of the screening rack 2.

[0039] Specifically, the conveying mechanism includes a conveyor roller 3 and a conveyor belt 4. The conveyor roller 3 rotates inside the screening box 1 through a second shaft rod provided, and there are two conveyor rollers 3. The conveyor belt 4 is arranged on the two conveyor rollers 3. The second shaft rod on the right conveyor roller 3 penetrates through the screening box 1 and is fixedly connected with a first gear 31 and a first pulley 32. The power mechanism is used to drive the first pulley 32 to rotate, and the first gear 31 is meshed with the second gear 51.

[0040] By adopting the above technical solution, the power mechanism can drive the first pulley 32 to rotate. The first pulley 32 can drive the conveying roller 3 to rotate through the second shaft rod. The right conveying roller 3 and another conveying roller 3 can drive the conveyor belt 4 to rotate synchronously. The rotating conveyor belt 4 can convey the materials falling on it. Among them, the first pulley 32 drives the first gear 31 to rotate through the second shaft rod at the same time. The first gear 31 and the second gear 51 are meshed and connected, so that the cam 5 provided in the screening mechanism can be driven to rotate at the same time, and then the screening mechanism and the conveying mechanism can operate simultaneously.

[0041] Specifically, the power mechanism includes a motor 6. The motor 6 is fixedly connected to one side of the screening box 1. The output shaft of the motor 6 is fixedly connected with a second pulley 61. The second pulley 61 drives the first pulley 32 to rotate synchronously through the provided transmission belt.

[0042] By adopting the above technical solution, the motor 6 provided in the power mechanism can drive the second pulley 61 to rotate. The second pulley 61 drives the first pulley 32 to rotate through the transmission belt, so that the first pulley 32 drives the first gear 31 and the conveying roller 3 to rotate. The first gear 31 can drive the meshed second gear 51 to rotate. The second gear 51 can drive the cam 5 to rotate. The cam 5 can squeeze the screening frame 2 to vibrate, so that the screening mechanism can be driven to vibrate and screen. The conveying roller 3 can drive the conveyor belt 4 to rotate and convey, so that the conveying mechanism can drive the materials to be conveyed.
