Description

Technical Field

[0001] This invention belongs to the field of dehydration and drying technology, specifically referring to a centrifugal dehydrator with a screw conveyor function. Background Technology

[0002] Particle materials such as coal powder mixed with water need to undergo screening and dewatering before collection and storage. Existing water removal methods mainly include filtration and drying. A single device often cannot achieve both functions, so the efficiency and effectiveness of dewatering cannot be guaranteed at the same time.

[0003] In addition, coal powder particles of different sizes need to be screened before they can be stored and used separately. However, existing equipment often dehydrates the powder first and then screens it. This post-screening method generates a lot of dust and affects the working environment. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a centrifugal dewatering machine with a screw conveyor function. Firstly, this invention utilizes the centrifugal force during rotation combined with a conical drum to screen coarse particles, while separating fine particles and water. Secondly, the unidirectional deformation design of the elastic baffles allows them to automatically open when material passes through and automatically close after flow stops (preventing backflow). Furthermore, the structural design of the drying components prevents water from splashing out of the filter cartridge and also prevents it from falling back onto the filter cartridge.

[0005] In addition, in the intermittent drainage mode, in order to prevent the water in the drainage component from flowing back after shutdown, the present invention also proposes an adaptive valve component, which uses the centrifugal force during rotation to automatically control the opening and closing of the elastic baffle, so as to achieve the technical effect of automatically opening when starting and automatically closing after shutdown.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a centrifugal dewatering machine with a screw conveying function, including a ramp diversion component, an adaptive valve component, a drying component, a collection component, a drainage component, a feeding component, and a discharging component. The feeding component is rotatably disposed in the drainage component, the ramp diversion component is disposed on the drainage component, the adaptive valve component is disposed in the drainage component, the drying component is disposed on the ramp diversion component, the collection component is disposed at the end of the drying component, and the discharging component is disposed in the collection component. The ramp diversion assembly includes a spiral cylinder and a conical drum. The outer wall of the spiral cylinder is provided with a ramp spiral section that matches the conical drum, and the outer wall of the spiral cylinder is also provided with a straight spiral section. The spiral cylinder is rotatably disposed in the conical drum.

[0007] After the material ejected from the centrifuge chamber impacts the inner wall of the conical drum, it tends to slide along the spiral section toward the straight drum. The inclined spiral section can push the coarse particles to overcome the inertia and move toward the filter cylinder, thereby achieving the initial screening of coarse particles and water.

[0008] The inclined spiral section and the straight spiral section are provided with holes for filtration.

[0009] The micropores on the inclined spiral section and the straight spiral section allow fine particles and water to pass through, while coarse particles are propelled by the rotation of the inclined spiral section and the straight spiral section, moving along the spiral cylinder toward the filter cylinder.

[0010] Furthermore, the adaptive valve assembly includes an inner retaining ring and an outer retaining ring. The inner retaining ring is fixed to the outer wall of the spiral cylinder, and the outer retaining ring is disposed in the drainage assembly. Independent elastic baffles are evenly distributed in a ring on the outer retaining ring, and the elastic baffles and the inner retaining ring abut and slide in contact.

[0011] The adaptive valve assembly has two opening methods. When the material flows from the spiral drum toward the rotary drum, it can push the elastic baffle to open. When the outer baffle ring rotates too fast with the rotary drum, the elastic baffle will also open under the action of centrifugal force. Through the above two opening methods, fine particles and water can pass through the adaptive valve assembly into the rotary drum, and the backflow of fine particles and water can be avoided after the machine stops.

[0012] Furthermore, the drying assembly includes a filter cylinder, a water baffle, and a drying layer. The filter cylinder is fixed to one end of a conical drum, and the filter cylinder is provided with an array of holes for screening and discharging water. The straight spiral section matches the inner wall of the filter cylinder, the water baffle is located outside the filter cylinder, and the drying layer is located on the inner wall of the water baffle.

[0013] By rotating the filter cylinder and heating the drying layer, the moisture contained in the coarse material can be separated, thereby achieving the technical purpose of drying and dehydration; the moisture that is not dried in time will flow down along the inner wall of the water baffle, preventing it from dripping back into the filter cylinder.

[0014] Furthermore, the collection assembly includes a scraper bracket, a collection scraper, and a collection cover. The scraper bracket is fixed to the discharge assembly, the collection scrapers are evenly distributed in a ring and fixed to the scraper bracket, and the collection cover is located outside the scraper bracket and the collection scrapers. The collection cover is also provided with a negative pressure pipe connected to the negative pressure pump.

[0015] During the discharge process, the discharge end plate scrapes off the material at the discharge hole through the collecting scraper, and then collects the dried coarse particles through negative pressure.

[0016] Furthermore, the drainage assembly includes a straight rotating drum and a drainage baffle. The straight rotating drum is fixed to the other end of the conical rotating drum, the outer retaining ring is fixed to the straight rotating drum, and the drainage baffle is fixed to the end of the straight rotating drum.

[0017] Preferably, the drainage assembly further includes an input pulley and a bearing, the drainage baffle is provided with a drainage hole, the bearing is disposed in the inner ring of the drainage baffle, and the input pulley is fixedly connected to the drainage baffle.

[0018] Input pulley one and input pulley two are connected to the same external output shaft. However, due to the diameter difference between input pulley one and input pulley two, there is also relative rotation between the screw drum and the conical drum. Under this driving mode, the material and water can move radially under the action of centrifugal force and axially under the driving action of the screw drum.

[0019] Furthermore, the feeding assembly includes a feeding pipe, one end of which is provided with a centrifuge chamber, the centrifuge chamber is fixedly connected to the spiral drum, the side of the centrifuge chamber is provided with a centrifuge window, and the spiral drum is provided with a window that coincides with the centrifuge window.

[0020] Preferably, the feeding assembly further includes a screw feeder and an input pulley II, wherein the screw feeder is fixedly connected to the feeding pipe and the input pulley II is fixedly connected to the end of the feeding pipe.

[0021] Furthermore, the discharge assembly includes a discharge end plate and a support shaft, the spiral cylinder is rotatably mounted on the support shaft, the discharge end plate is fixed to the filter cylinder, and the discharge end plate is rotatably mounted on the support shaft.

[0022] The scraper bracket is fixed to the support shaft, and the discharge end plate is provided with discharge holes in a ring, corresponding to the collecting scraper.

[0023] The beneficial effects achieved by the present invention using the above structure are as follows: (1) After the material thrown out of the centrifuge chamber hits the inner wall of the conical drum, it tends to slide along the spiral cylinder toward the straight drum. The inclined spiral section can push the coarse particles to overcome the above inertia and move toward the filter cylinder, thereby achieving the preliminary screening of coarse particles and water.

[0024] (2) The micropores on the inclined spiral section and the straight spiral section allow fine particles and water to pass through, while coarse particles will move along the spiral cylinder toward the filter cylinder under the rotation of the inclined spiral section and the straight spiral section.

[0025] (3) The adaptive valve assembly has two opening methods. When the material flows from the spiral drum toward the straight drum, it can push the elastic baffle to open. When the outer baffle ring rotates too fast with the straight drum, the elastic baffle will also open under the action of centrifugal force. Through the above two opening methods, fine particles and water can pass through the adaptive valve assembly into the straight drum, and the backflow of fine particles and water can be avoided after the machine stops.

[0026] (4) By rotating the filter cylinder and heating the drying layer, the moisture contained in the coarse material can be separated, thereby achieving the technical purpose of drying and dehydration; the moisture that is not dried in time will flow down along the inner wall of the baffle, preventing it from dripping back into the filter cylinder.

[0027] (5) During the process of rotating and discharging, the discharge end plate can scrape the material at the discharge hole through the collection scraper, and then collect the dried coarse particles through negative pressure.

[0028] (6) Input pulley one and input pulley two are connected to the same output shaft outside. However, due to the diameter difference between input pulley one and input pulley two, there is also relative rotation between the spiral drum and the conical drum. Under this driving mode, the material and water can move radially under the action of centrifugal force and move axially under the driving action of the spiral drum. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0034] like Figures 1-10 As shown, the present invention proposes a centrifugal dewatering machine with screw conveying function, including a ramp diversion component 1, an adaptive valve component 2, a drying component 3, a collection component 4, a drainage component 5, a feeding component 6, and a discharge component 7. The feeding component 6 is rotatably disposed in the drainage component 5, the ramp diversion component 1 is disposed on the drainage component 5, the adaptive valve component 2 is disposed in the drainage component 5, the drying component 3 is disposed on the ramp diversion component 1, the collection component 4 is disposed at the end of the drying component 3, and the discharge component 7 is disposed in the collection component 4. The ramp diversion assembly 1 includes a spiral cylinder 11 and a conical drum 12. The outer wall of the spiral cylinder 11 is provided with a ramp spiral section 111 that matches the conical drum 12. The outer wall of the spiral cylinder 11 is also provided with a straight spiral section 112. The spiral cylinder 11 is rotatably disposed in the conical drum 12.

[0035] After the material ejected from the centrifuge chamber 611 impacts the inner wall of the conical drum 12, it tends to slide along the spiral cylinder 11 toward the straight drum 51. The inclined spiral section 111 can push the coarse particles to overcome the aforementioned inertia and move toward the filter cylinder 31, thereby achieving preliminary screening of coarse particles and water.

[0036] The inclined spiral section 111 and the straight spiral section 112 are provided with holes for filtering.

[0037] The micropores on the inclined spiral section 111 and the straight spiral section 112 allow fine particles and water to pass through, while coarse particles are propelled by the rotation of the inclined spiral section 111 and the straight spiral section 112 and move along the spiral cylinder 11 toward the filter cylinder 31.

[0038] The adaptive valve assembly 2 includes an inner retaining ring 21 and an outer retaining ring 22. The inner retaining ring 21 is fixed to the outer wall of the spiral cylinder 11, and the outer retaining ring 22 is disposed in the drainage assembly 5. Independent elastic baffles 221 are evenly distributed in a ring on the outer retaining ring 22. The elastic baffles 221 and the inner retaining ring 21 abut and slide in contact.

[0039] The adaptive valve assembly 2 has two opening modes. When the material flows from the spiral drum 11 toward the rotary drum 51, it can push the elastic baffle 221 to open. When the outer baffle ring 22 rotates too fast with the rotary drum 51, the elastic baffle 221 will also open under the action of centrifugal force. Through the above two opening modes, fine particles and water can pass through the adaptive valve assembly 2 into the rotary drum 51, and the backflow of fine particles and water can be avoided after the machine stops.

[0040] The drying assembly 3 includes a filter cylinder 31, a water baffle 32, and a drying layer 33. The filter cylinder 31 is fixed to one end of the conical drum 12, and the filter cylinder 31 is provided with an array of holes for screening and discharging water. The straight spiral section 112 matches the inner wall of the filter cylinder 31, the water baffle 32 is located outside the filter cylinder 31, and the drying layer 33 is located on the inner wall of the water baffle 32.

[0041] By rotating the filter cylinder 31 and heating the drying layer 33, the moisture contained in the coarse material can be separated, thereby achieving the technical purpose of drying and dehydration; the moisture that is not dried in time will flow down along the inner wall of the water baffle 32, preventing it from dripping back into the filter cylinder 31.

[0042] The collection component 4 includes a scraper bracket 41, a collection scraper 42, and a collection cover 43. The scraper bracket 41 is fixed to the discharge component 7. The collection scraper 42 is evenly distributed in a ring and fixed to the scraper bracket 41. The collection cover 43 is located outside the scraper bracket 41 and the collection scraper 42. The collection cover 43 is also provided with a negative pressure pipe 431 connected to the negative pressure pump.

[0043] During the discharge process, the discharge end plate 71 can scrape the material at the discharge hole 711 by the collecting scraper 42, and then collect the dried coarse particles by negative pressure.

[0044] The drainage assembly 5 includes a straight rotating drum 51 and a drainage baffle 52. The straight rotating drum 51 is fixed to the other end of the conical rotating drum 12, the outer retaining ring 22 is fixed to the straight rotating drum 51, and the drainage baffle 52 is fixed to the end of the straight rotating drum 51.

[0045] The drainage assembly 5 also includes an input pulley 53 and a bearing 54. The drainage baffle 52 is provided with a drainage hole 521. The bearing 54 is located in the inner ring of the drainage baffle 52. The input pulley 53 is fixedly connected to the drainage baffle 52.

[0046] Input pulley 53 and input pulley 63 are connected to the same external output shaft. However, due to the diameter difference between input pulley 53 and input pulley 63, there is also relative rotation between the spiral drum 11 and the conical drum 12. Under this driving mode, the material and water can move radially under the action of centrifugal force and axially under the driving action of the spiral drum 11.

[0047] The feeding assembly 6 includes a feeding pipe 61, one end of which is provided with a centrifuge chamber 611, which is fixedly connected to the screw cylinder 11. The side of the centrifuge chamber 611 is provided with a centrifuge window 612, and the screw cylinder 11 is provided with a window that coincides with the centrifuge window 612.

[0048] The feeding assembly 6 also includes a screw feeder 62 and an input pulley 63. The screw feeder 62 is fixedly connected to the feeding pipe 61, and the input pulley 63 is fixedly connected to the end of the feeding pipe 61.

[0049] The discharge assembly 7 includes a discharge end plate 71 and a support shaft 72. The spiral cylinder 11 is rotatably mounted on the support shaft 72, and the discharge end plate 71 is fixedly connected to the filter cylinder 31. The discharge end plate 71 is rotatably mounted on the support shaft 72.

[0050] The scraper bracket 41 is fixed to the support shaft 72, and the discharge end plate 71 is provided with discharge holes 711 that correspond to the collecting scraper 42 in a ring.

[0051] In practical use, the user drives input pulley 53 and input pulley 63 through the same input shaft. Since there is a diameter difference between input pulley 53 and input pulley 63, the spiral cylinder 11 and the conical drum 12 will rotate relative to each other while rotating at high speed in the same direction. The mixed material (such as coal powder containing water) enters the centrifuge chamber 611 through the end of the feed pipe 61. When the material rotates in the centrifuge chamber 611, it will enter the interlayer between the spiral drum 11 and the conical drum 12 through the centrifuge window 612 under the action of centrifugal force. After the material impacts the inner wall of the conical drum 12, under the combined action of inertia and centrifugal force, it tends to expand outward along the inner wall of the conical drum 12. Due to the filtering effect of the inclined spiral section 111, fine particles and water will pass through the inclined spiral section 111 and enter the interlayer between the spiral cylinder 11 and the straight drum 51, while the wet coarse particles will enter the interlayer between the spiral cylinder 11 and the filter cylinder 31 under the rotational push of the inclined spiral section 111; thus completing the preliminary screening.

[0052] As the outer baffle ring 22 rotates with the straight drum 51, the elastic baffle 221 opens under the action of centrifugal force. At this time, the water and fine particles diverted by the inclined diversion component 1 will enter the straight drum 51 through the adaptive valve component 2 and then be discharged through the drain hole 521. Depending on the moisture content of the raw material, the drainage component 5 can be set to two modes: continuous drainage and intermittent drainage. If the moisture content of the raw material is low, the intermittent drainage mode is adopted: the drainage hole 521 is blocked, fine particles and water are stored between the adaptive valve component 2 and the drainage baffle 52, and periodic cleaning is performed. During shutdown cleaning, since the elastic baffle 221 has been closed due to the stop of the rotary drum 51, the material located between the adaptive valve component 2 and the drainage baffle 52 will not flow back. If the raw material has a high moisture content, a continuous drainage mode is adopted: the drain hole 521 is not blocked, and the external part of the drain hole 521 is set with a rotating seal of the drain baffle 52 to receive the fine particles and water after they are discharged into the receiving container and then discharged through the pipe.

[0053] The material located between the spiral drum 11 and the filter drum 31 moves slowly toward the discharge assembly 7 under the relative rotation of the straight spiral section 112 and the filter drum 31. During the movement of the material inside the filter drum 31, the residual moisture in the coarse particles will be thrown onto the water baffle 32 through the filter drum 31 and evaporated by the drying layer 33. The moisture that has not yet evaporated will slide down along the water baffle 32 and will not fall back onto the filter drum 31. Meanwhile, the heat from the drying layer 33 will also radiate into the interior of the filter cartridge 31, further drying the material that has undergone centrifugal dehydration.

[0054] After the dried material reaches the end of the spiral drum 11 and the filter drum 31, it is discharged through the discharge hole 711. The collecting scraper 42 can scrape the end face of the rotating discharge end plate 71 to avoid the accumulation of material at the discharge hole 711.

[0055] The scraped material accumulates on the collecting scraper 42, and is then drawn out through the negative pressure pipe 431 under the action of an external pump.

[0056] As another new embodiment of the present invention: the conical drum 12 is provided with an inspection port, and the detection probe can enter the interlayer used for spiral conveying through the inspection port. When the probe moves along the inclined spiral section 111 and the straight spiral section 112, it can visually detect the wear condition of the spiral drum 11.
