Description

Technical Field

[0001] This utility model relates to the field of oil sand treatment technology, and in particular to an oil sand treatment device. Background Technology

[0002] Oil sands typically contain high levels of organic matter (oil content), have high calorific value, but also high moisture and ash content, thus possessing high recycling value. Currently, recycled oil sands usually undergo pretreatment, such as dehydration (mechanical dehydration such as centrifugation, pressure filtration, or thermal drying), impurity removal (removal of large solids, metals, etc.), and homogenization (stirring, grinding). After pretreatment, the homogenized oil sands are usually filtered and screened again to obtain oil sands that meet the requirements for mixing with biomass powder to form a blended fuel with a more stable overall calorific value, which is more suitable for subsequent thermochemical conversion (such as incineration, gasification, pyrolysis, co-coking). In order to meet the high requirements for raw material particle size and purity of subsequent processes (such as mixing with biomass powder to prepare fuel, incineration, gasification, pyrolysis, or co-coking), the homogenized oil sands usually need to be further screened to separate oil sand particles that meet the target particle size range and remove excessively coarse components and residual impurities.

[0003] Currently, the secondary filtration and screening of homogenized oil sands mainly relies on traditional screening equipment, such as vibrating screens, drum screens, or fixed screens. Traditional equipment is usually a single-pass screening method, and coarse particles or lumps that do not pass through the screen are often discharged directly as oversize material. The lack of an effective internal circulation mechanism for multiple screenings may reduce the overall screening efficiency and the yield of qualified products.

[0004] Therefore, it is necessary to provide a new oil sands treatment device to solve the above-mentioned technical problems. Utility Model Content

[0006] The oil sand treatment device provided by this utility model includes a sand-sliding plate. The bottom of the sand-sliding plate is provided with a fan-shaped part, and a stainless steel screen for filtering oil sand is installed on the fan-shaped part. A collection cylinder is fixedly installed at the tail of the fan-shaped part, and two sets of vertically arranged spiral feeders are installed inside the collection cylinder.

[0007] The slip plate is also equipped with a support for supporting the slip plate.

[0008] Preferably, the housings of the two sets of screw feeders are fixedly connected to each other, the bottom housing of the screw feeder is provided with a feed inlet, and the top housing of the screw feeder is fixedly installed with a discharge hopper inclined toward the stainless steel screen.

[0009] Preferably, the material collecting cylinder is equipped with a rotating material feeding plate on the side opposite to the feed inlet of the screw feeder.

[0010] Preferably, a base is fixedly installed at the bottom of the collecting cylinder, and a drive motor for driving the feeding plate is installed inside the base.

[0011] Preferably, the collecting cylinder is equipped with a rotatably connected arc-shaped door on the cylinder wall away from the screw feeder, and the arc-shaped door is equipped with a door lock.

[0015] This invention automatically circulates unqualified coarse particles for multiple screenings, greatly increasing their chances of passing through the screen and effectively improving the overall screening efficiency and the yield of qualified oil sand. At the same time, the oil sand particles come into contact with the stainless steel screen and move relative to it during the sliding process, which reduces their adhesion tendency compared to static or high-frequency vibration screening methods. The fan-shaped sliding sand plate combined with the inclined screen surface design provides a natural material sliding channel, which is beneficial to material distribution and screening.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides an oil sand treatment device, which includes a sand-sliding plate 1, a stainless steel screen 2, a collection cylinder 3, and a screw feeder 4.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 3 The bottom of the sand-slipping plate 1 is provided with a fan-shaped part 11, and a stainless steel screen 2 for filtering oil sand is installed on the fan-shaped part 11. A collection cylinder 3 is fixedly installed at the tail of the fan-shaped part 11, and two sets of vertically arranged screw feeders 4 are installed in the collection cylinder 3. The shells of the two sets of screw feeders 4 are fixedly connected to each other. The bottom shell of the screw feeder 4 is provided with a feed inlet 4a, and a discharge hopper 41 inclined towards the stainless steel screen 2 is fixedly installed on the top shell of the screw feeder 4.

[0024] It should be noted that after the pretreated oil sand is poured into the collection cylinder 3, the screw feeder 4 is turned on, so that the screw feeder 4 can discharge the oil sand through the discharge hopper 41 onto the sliding plate 1. Since the sliding plate 1 is inclined, the oil sand can be filtered and screened by sliding through the stainless steel screen 2. The oil sand that is not successfully filtered slides back into the collection cylinder 3 and is then conveyed to the sliding plate 1 by the screw feeder 4 for secondary filtration.

[0025] Initially unqualified coarse particles are automatically circulated and screened multiple times, greatly increasing their chances of passing through the screen and effectively improving the overall screening efficiency and the yield of qualified oil sand. At the same time, the oil sand particles come into contact with the stainless steel screen 2 and move relative to each other during the sliding process, and their adhesion tendency is reduced compared with static or high-frequency vibration screening methods. The fan-shaped sliding sand plate 1, combined with the inclined screen surface design, provides a natural material sliding channel, which is conducive to material distribution and screening.

[0026] It is worth noting that in this application, a vibrating motor for driving the stainless steel screen 2 to vibrate can also be installed on the sand-sliding plate 1, thereby reducing the problem of slow sliding speed of oil sand on the stainless steel screen 2.

[0027] Among them, sand-enclosing baffles 12 are fixedly installed at the edges of the sand-slipping plate 1 and the fan-shaped part 11 to prevent oil sand from slipping off from the edges of the sand-slipping plate 1 or the fan-shaped part 11.

[0028] Furthermore, a rotating material-pulling plate 5 is installed on the side of the collecting cylinder 3 that is offset from the feed inlet 4a of the screw feeder 4, and a base 31 is fixedly installed at the bottom of the collecting cylinder 3. A drive motor for driving the material-pulling plate 5 is installed in the base 31. When the drive motor is turned on, the material-pulling plate 5 is rotated, so that the oil sand located in the dead corner on the side of the collecting cylinder 3 is stirred and driven to be discharged to the feed inlet 4a of the screw feeder 4.

[0029] Furthermore, an arc-shaped door 32 with a rotating connection is installed on the cylinder wall of the collecting cylinder 3 away from the screw feeder 4, and a door lock is installed on the arc-shaped door 32. The remaining material can be discharged by opening the arc-shaped door 32.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 3 The slip plate 1 is also equipped with a support member 6 for supporting the slip plate 1. The support member 6 includes a diagonal brace 61. The top of the diagonal brace 61 is equipped with a rotating frame 62 that is rotatably connected, and the rotating frame 62 is fixedly installed on the slip plate 1. The bottom of the diagonal brace 61 is rotatably connected to a support plate 63 through a rotating bracket.

[0031] It should be noted that the rotating diagonal brace 61 supports the sliding sand plate 1. When necessary, a counterweight can be placed on the support plate 63. Therefore, the diagonal brace 61, together with the base 31, can effectively support the sliding sand plate 1. The tilt angle of the stainless steel screen 2 can also be adjusted according to actual needs.

[0032] The working principle of the oil sand treatment device provided by this utility model is as follows:

[0033] The rotating diagonal brace 61 supports the sliding sand plate 1. If necessary, a counterweight can be placed on the support plate 63 to prevent tipping. A collection device can be placed at the bottom of the stainless steel screen 2 to collect the screened oil sand. After the pre-treated oil sand is poured into the collection cylinder 3, the screw feeder 4 is turned on, allowing the oil sand to be discharged through the discharge hopper 41 onto the sliding sand plate 1. Because the sliding sand plate 1 is inclined, the initial oil sand can be filtered and screened by sliding through the stainless steel screen 2, while unfiltered oil sand... The oil sand slides back into the collection cylinder 3 and is then conveyed again by the screw feeder 4 to the sliding sand plate 1 for secondary screening, realizing automatic circulation screening of oil sand particles, greatly increasing their screening opportunities, effectively improving the overall screening efficiency and the collection rate of qualified oil sand. At the same time, during the sliding process, the oil sand particles come into contact with the stainless steel screen 2 and are prevented from adhering to the stainless steel screen and affecting the screening effect under the action of the vibrating motor. The fan-shaped sliding sand plate 1, combined with the inclined screen surface design, provides a natural material sliding channel, which is conducive to material distribution and screening.

[0034] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
