Description

Technical Field

[0001] This utility model relates to the field of ultra-fine material processing technology for filter presses, and in particular to an ultra-dry powder unloading and conveying device for filter presses. Background Technology

[0002] When processing extremely fine materials, the filter press system uses a "four-in-one vacuum drying system" and a "blowing dehydration system" to reduce the material moisture content to below 40%. After processing, a discharge conveying device is required for subsequent unloading and transfer of the material.

[0003] When using traditional ultra-dry powder unloading and conveying devices for filter presses, the net height of the unloaded material after processing is often greater than 70cm. If the material falls more than 1.5m, the rapid drop when the filter plates open generates significant amounts of dust. Traditional dust control methods during unloading typically include installing a simple receiving trough below the filter press, using a conventional dust collector, or adding a water mist spraying system to reduce dust. However, simple receiving troughs lack sealing and negative pressure suction, conventional dust collectors are inefficient, and water mist spraying systems can negatively impact material quality. Excessive dust not only hinders clean production in factories but also increases environmental pollution and occupational disease risks in the production area. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an ultra-dry powder unloading and conveying device for filter presses, which aims to improve the problem that existing filter presses generate a large amount of smoke and dust during the unloading process of ultra-dry powder, and traditional smoke and dust treatment devices are ineffective. As a result, the smoke and dust not only affect the clean production of the factory, but also increase the environmental pollution and occupational disease risk in the production area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a super-dry powder unloading and conveying device for a filter press, comprising a frame, a filter press mounted on the top of the frame, a unloading assembly at the bottom of the filter press, the unloading assembly including a receiving hopper fixedly connected to the bottom of the filter press, multiple suction ports opened and penetrating through the inner wall of the receiving hopper, a discharge bin fixedly connected to the bottom of the receiving hopper, dust suction pipes penetrating through the inner walls of both the receiving hopper and the discharge bin, a dust collector installed at one end of the dust suction pipe, a ventilation pipe installed at the top of the dust collector, an induced draft fan installed at one end of the ventilation pipe, a discharge pipe penetrating through the inner wall of the discharge bin, and an auxiliary vibration assembly at the bottom of the discharge bin.

[0006] The above technical solution provides support for the filter press via a frame, facilitating operator operation. A discharge assembly ensures the absorption of dust during discharge. A receiving hopper directly connects to the lower end of the filter press. A suction port absorbs the first wave of dust generated during discharge. A discharge hopper collects the processed material. A dust collection pipe connects both the receiving hopper and the discharge hopper to a dust collector, which collects and filters the dust. An induced draft fan draws out internal air, creating negative pressure. A discharge pipe facilitates the subsequent transfer and processing of the discharged material.

[0007] As a further description of the above technical solution:

[0008] Preferably, the auxiliary vibration assembly includes a protective shell, which is fixedly connected to the bottom of the feeding hopper. A motor is fixedly connected to the inner wall of the feeding hopper, and a rotating shaft is fixedly connected to the output end of the motor. A turntable is fixedly connected to the outer wall of the rotating shaft, and an eccentric column is fixedly connected to the outer wall of the turntable. An outer ring is slidably connected to the outer wall of the eccentric column. Multiple limiting blocks and limiting rods are provided inside the protective shell. A receiving plate is fixedly connected to the inner wall of the feeding hopper, and a spring steel is fixedly connected to the bottom end of the receiving plate.

[0009] The above technical solution provides protection for the internal components through a protective shell and provides certain support for the top feeding hopper. A motor drives the rotating shaft to rotate, which in turn drives the turntable and the eccentric column on the outer wall of the turntable to rotate. The eccentric column drives the outer ring to slide. The linkage between the limit block and the limit rod ensures that the outer ring always maintains reciprocating sliding in the vertical direction, thereby causing the spring steel at the top to vibrate continuously, which in turn causes the receiving plate, the feeding hopper, and the receiving bucket at the top to vibrate together, helping the material to slide down and disperse.

[0010] As a further description of the above technical solution:

[0011] Preferably, a support plate is fixedly connected to the right side of the frame, and the induced draft fan is installed on the top of the support plate.

[0012] The above technical solution provides support for the installation of the support plate through the frame, and raises and installs the induced draft fan through the support plate, so that the induced draft fan's pipe can be connected to the dust collector outlet to form negative pressure.

[0013] As a further description of the above technical solution:

[0014] Preferably, sealing gaskets are provided at the joints between the filter press and the receiving hopper, as well as at the joints between the receiving hopper and the discharge bin, and a filter plate is fixedly connected to the inner wall of the suction port.

[0015] The above technical solution ensures that both joints are sealed by a sealing gasket to maintain a negative pressure effect, and filters dust and materials by a filter plate to prevent materials from being sucked out through the suction port.

[0016] As a further description of the above technical solution:

[0017] Preferably, one of the limiting blocks is fixedly connected to the outer wall of the outer ring, and one of the limiting rods is fixedly connected to the opposite side of the inner wall of the protective shell, with the limiting block slidably connected to the outer wall of the limiting rod.

[0018] The above technical solution involves a limiting block fixed to the outer wall of the outer ring, which is slidably connected to the outer wall of the limiting rod fixed inside the protective shell, thereby limiting the sliding of the outer ring for the first time.

[0019] As a further description of the above technical solution:

[0020] Preferably, one of the limiting blocks is fixedly connected to the top of the protective shell, and one of the limiting rods is fixedly connected to the top of the outer ring, wherein the limiting rod is slidably connected to the inner wall of the limiting block.

[0021] The above technical solution involves a limiting rod fixedly connected to the top of the outer ring and slidably connected to the inner wall of the limiting block fixed to the top of the protective shell, thereby limiting the sliding of the outer ring for the second time. Through these two limiting actions, the rotation of the turntable is ultimately converted into the linear reciprocating sliding of the outer ring.

[0022] As a further description of the above technical solution:

[0023] Preferably, the top end of the limiting rod is fixedly connected to the bottom end of the spring steel, and the two ends of the spring steel are installed on the top end of the protective shell.

[0024] The above technical solution involves the outer ring driving the limiting rod to slide synchronously, which in turn drives the spring steel to slide synchronously back and forth, thereby generating vibration. The top of the protective shell then provides support for the spring steel.

[0025] As a further description of the above technical solution:

[0026] Preferably, the inner wall of the protective shell has a working groove that extends through it, the turntable is rotatably connected in the working groove, and the outer ring is slidably connected in the working groove.

[0027] The above technical solution ensures that the rotation of the turntable and the sliding of the outer ring are not affected by the opening of the working groove, while preventing the protective shell from being sealed and helping the internal motor to dissipate heat.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the receiving hopper is closely attached to the lower end of the filter press to receive the material, and the suction ports evenly distributed on the receiving hopper are used to absorb the dust. The dust suction pipe connects the receiving hopper and the discharge bin below, and the dust is absorbed into the dust collector. The dust collector is connected by an induced draft fan, so that a sealed and negative pressure environment is formed inside the device, which absorbs and concentrates the dust while preventing the dust from affecting the outside.

[0030] 2. In this utility model, the rotating shaft is driven by a motor to rotate, and the rotating shaft drives the turntable and eccentric column to rotate synchronously. The spring steel is driven to vibrate vertically through the linkage of the outer ring and the limiting device, which prevents the accumulation and blockage of materials during the falling process. At the same time, the vibration helps the materials on the inner wall of the receiving hopper to fall faster. Attached Figure Description

[0038] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an ultra-dry powder unloading and conveying device for a filter press, comprising a frame 1, a filter press 102 mounted on the top of the frame 1, and a unloading assembly 2 at the lower end of the filter press 102. The unloading assembly 2 includes a receiving hopper 201, which is fixedly connected to the lower end of the filter press 102. Multiple suction ports 203 are opened and penetrated through the inner wall of the receiving hopper 201. A discharge bin 205 is fixedly connected to the bottom end of the receiving hopper 201. Dust suction pipes 206 penetrate the inner walls of both the receiving hopper 201 and the discharge bin 205. A dust collector 207 is installed at one end of the suction pipe 206, a ventilation pipe 208 is installed at the top of the dust collector 207, an induced draft fan 209 is installed at one end of the ventilation pipe 208, a discharge pipe 210 runs through the inner wall of the feeding bin 205, an auxiliary vibration component 3 is installed at the bottom of the feeding bin 205, a support plate 101 is fixedly connected to the right side of the frame 1, the induced draft fan 209 is installed at the top of the support plate 101, the top of the limit rod 308 is fixedly connected to the bottom of the spring steel 309, and both ends of the spring steel 309 are installed at the top of the protective shell 301.

[0040] Specifically, the upper part of the funnel-shaped receiving hopper 201 is closely attached to the lower part of the filter press 102. A sealing gasket 202 composed of rubber plates is installed at the joint. Negative pressure suction ports 203 are evenly distributed along the upper edge of the receiving hopper 201. The side and bottom of the receiving hopper 201 are inclined at an angle of 55 degrees. At the bottom of the hopper is the discharge bin 205. Both the receiving hopper 201 and the discharge bin 205 are connected by a dust suction pipe 206. The other end of the dust suction pipe 206 is connected to the dust collector 207. The outlet of the dust collector 207 is connected to a powerful induced draft fan 209 through a ventilation pipe 208. When the induced draft fan 209 is started, it draws out the internal gas, forming a negative pressure inside and in the pipe, generating suction to suck out the dust generated during unloading and collect it in the dust collector 207. Finally, the induced draft fan 209 only discharges clean air. The entire process ensures that the unloaded material is always in a closed environment, and the generated dust will not affect the outside.

[0041] Reference Figure 2 , Figure 4 and Figure 5The auxiliary vibration component 3 includes a protective shell 301, which is fixedly connected to the bottom of the feeding bin 205. A motor 302 is fixedly connected to the inner wall of the feeding bin 205. A rotating shaft 303 is fixedly connected to the output end of the motor 302. A turntable 304 is fixedly connected to the outer wall of the rotating shaft 303. An eccentric column 305 is fixedly connected to the outer wall of the turntable 304. An outer ring 306 is slidably connected to the outer wall of the eccentric column 305. Multiple limiting blocks 307 and limiting rods 308 are provided inside the protective shell 301. A receiving plate 310 is fixedly connected to the inner wall of the feeding bin 205. A spring steel 309 is fixedly connected to the bottom end of the receiving plate 310.

[0042] Specifically, the protective shell 301 provides support for the top feeding hopper 205 and protects the internal components. After the material passes through the receiving hopper 201 and the feeding hopper 205, it first falls onto the upper surface of the receiving plate 310. Then, it compresses the spring steel 309 at the bottom of the receiving plate 310 to buffer the impact, reduce damage to the device, reduce operating costs, and reduce dust generation. Afterward, the motor 302 drives the rotating shaft 303 to rotate the turntable 304. When the turntable 304 rotates, it uses the principle of eccentric wheels and multiple limit blocks 307 and limit rods to control the rotation. The combined limiting mechanism of 308 and the eccentric column 305 on the outer wall of the turntable 304 will drive the outer ring 306 to slide vertically, thereby changing the direction of movement. The outer ring 306, through the limiting block 307 at its top, drives the spring steel 309, which in turn drives the receiving plate 310 to move vertically, shaking and scattering the material above, further distributing it evenly above, preventing material accumulation and blockage. At the same time, since the receiving plate 310 is fixedly connected to the inner wall of the discharge bin 205, this vibration will be transmitted to the receiving hopper 201 above, helping the material to slide down faster and reducing dust generation.

[0043] Reference Figure 1 and Figure 2 Sealing gaskets 202 are provided at the joints of the filter press 102 and the receiving hopper 201, as well as at the joints of the receiving hopper 201 and the discharge bin 205. Filter plates 204 are fixedly connected to the inner wall of the suction port 203.

[0044] Specifically, sealing gaskets 202 are installed at the two seams to ensure a sealing effect, thereby creating a negative pressure inside the unloading assembly 2, which helps unload materials and absorb dust. At the same time, the filter plate 204 installed on the inner wall of the suction port 203 ensures that materials will not be sucked into the suction pipe 206.

[0045] Reference Figure 4 and Figure 5One of the limiting blocks 307 is fixedly connected to the outer wall of the outer ring 306, and one of the limiting rods 308 is fixedly connected to the opposite side of the inner wall of the protective shell 301. The limiting block 307 is slidably connected to the outer wall of the limiting rod 308. One of the limiting blocks 307 is fixedly connected to the top of the protective shell 301, and one of the limiting rods 308 is fixedly connected to the top of the outer ring 306. The limiting rod 308 is slidably connected to the inner wall of the limiting block 307.

[0046] Specifically, the limiting block 307, which is fixedly connected to the outer wall of the right side of the outer ring 306, is slidably connected to the outer wall of the limiting rod 308, which is fixed to the inner wall of the protective shell 301. The limiting rod 308, which is fixedly connected to the top of the outer ring 306, is slidably connected to the inner wall of the limiting block 307, which is fixed to the top of the protective shell 301. Through these two limiting actions, the outer ring 306 can maintain vertical reciprocating sliding at all times when it is driven to run by the eccentric column 305, thereby causing the top component to vibrate.

[0047] Reference Figure 5 The inner wall of the protective shell 301 has a working groove that extends through it, the turntable 304 is rotatably connected in the working groove, and the outer ring 306 is slidably connected in the working groove.

[0048] Specifically, the internal components are protected and fixed by the protective shell 301, and the working groove is provided to ensure that the rotation of the turntable 304 and the up and down sliding of the outer ring 306 and the limit rod 308 are not affected. At the same time, the working groove is used to dissipate heat from the motor 302.

[0049] Working principle: When using this unloading and conveying device, the material is first processed by the filter press 102. Then, the induced draft fan 209 is started to extract air, creating a negative pressure in the dust collector 207, suction pipe 206, discharge hopper 205, and suction port 203. The material is then discharged from the filter press 102. Due to gravity and the negative pressure of components such as the receiving hopper 201 below, the dried material slides down along the inner wall of the receiving hopper 201. The dust generated during the descent is attracted by the negative pressure environment and enters the dust collector 207 through the suction pipe 206, where it is collected and stored. The exhaust from the outlet of the induced draft fan 209 is also clean air. The material continues to slide down to the bottom discharge hopper 205 for storage, and can then be taken out from the discharge pipe 210. The dust generated during the unloading and descent process is in a closed space and will not spread to the outside to affect personnel and the environment.

[0050] During the unloading process, the motor 302 is started, which drives the rotating shaft 303 and the turntable 304 to rotate. The eccentric column 305 installed on the outer wall of the turntable 304 drives the outer ring 306 to move during rotation. Under the limiting action of multiple limit blocks 307 and limit rods 308, the outer ring 306 eventually slides back and forth in the vertical direction, causing the upper spring steel 309 to slide together, generating vibration on the receiving plate 310. This prevents the material from falling onto the receiving plate 310 and accumulating and blocking the upper pipe, while transmitting the vibration to the inner wall of the receiving hopper 201, thereby helping the material slide down to the discharge port more quickly and reducing the generation of smoke and dust.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
