Description

Technical Field

[0001] This utility model relates to the technical field of methanol fuel production equipment, specifically to an integrated device for impurity precipitation and filtration in methanol fuel production. Background Technology

[0002] In the production of methanol fuel, impurities such as mechanical impurities, gums, and trace byproducts generated during the reaction directly affect the purity, stability, and combustion performance of the methanol fuel. Therefore, the separation and treatment of impurities is a crucial step in the methanol fuel production process. Currently, the industry typically treats impurities in methanol fuel through two steps: sedimentation and filtration. First, the impurities are allowed to settle under gravity through settling or stirring. Then, the supernatant is introduced into a filtration device for fine filtration.

[0003] However, sedimentation and filtration are carried out in different equipment, which requires additional conveying equipment and operating steps, increasing the production cycle and energy consumption, and is not conducive to continuous production. The stirring components in traditional sedimentation equipment are mostly fixed-angle blades, which cannot adjust the stirring angle and intensity according to the characteristics of impurities, such as density and particle size. This can easily lead to uneven local sedimentation or impurity suspension, affecting sedimentation efficiency. Sedimentation and filtration equipment are set up independently, which not only occupies a lot of space but also increases equipment investment costs. Moreover, the coordination between the two is poor, making it difficult to achieve precise control of the impurity treatment process. Utility Model Content

[0004] The existing technology for treating impurities in methanol fuel, as described in the background, typically involves two steps: precipitation and filtration. This results in a cumbersome process, low efficiency, and limited stirring effect.

[0007] Furthermore, the upper end of the worm gear is hexagonal, a cap is provided above the rotating drum, the cap is threadedly connected to the rotating drum, and both the worm gear and the worm wheel are located inside the rotating drum.

[0008] Furthermore, the limiting component includes a limiting plate, which is disposed above the tank body. One end of the limiting plate is mounted on the rotating drum, and a limiting bolt is provided between the limiting plate and the tank body. One end of the limiting bolt passes through the limiting plate and is inserted into the tank body.

[0009] Furthermore, the filter assembly includes multiple filter plates, which are arranged in a fan shape and evenly distributed around the axis of the rotating drum. Each filter plate has a connecting plate installed on its side that is close to each other. The connecting plate has connecting holes, and the connecting holes on two adjacent connecting plates are connected by fixing bolts. A support member is provided on the side of the filter plate that is close to the rotating drum, and the other side of the filter plate is connected to the tank body by fixing bolts.

[0011] Furthermore, a controller is provided on the front side of the tank, and an inspection door is provided on the rear side of the tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model integrates a rotating drum, stirring plate, and filter assembly inside the tank, enabling the sedimentation and filtration of impurities in methanol fuel to be completed in the same equipment. This eliminates the need for additional conveying equipment and separate operations, effectively shortening the production cycle and reducing energy consumption.

It also solves the problems of poor coordination and cumbersome processes caused by the independent setting of traditional sedimentation and filtration equipment.

[0013] 2. This utility model utilizes an angle adjustment component to flexibly adjust the angle of the stirring plate according to the density, particle size, and other characteristics of the impurities. Combined with the rotating drum driving the stirring plate to rotate, the stirring intensity can be precisely controlled, avoiding uneven local sedimentation or suspended impurities. At the same time, the multi-layer filtration component can perform step-by-step fine filtration of the sedimented impurities, improving the thoroughness of impurity separation, achieving precise control over the impurity treatment process, and ensuring the purity and quality of methanol fuel.

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0017] Please see Figure 1 , Figure 2 This utility model discloses an integrated impurity precipitation and filtration device for methanol fuel production, comprising a tank 1 made of 316 stainless steel, which has the characteristics of methanol corrosion resistance and high strength. The inner wall is polished to reduce impurity adhesion. A controller 15 is installed on the front side of the tank 1, which is equipped with a touch screen and PLC control system. An inspection door 16 is installed on the rear side of the tank 1, and the edge of the inspection door 16 is equipped with an oil-resistant rubber sealing strip. After closing, it is pressed tightly by the door lock to ensure the airtightness of the tank 1. A feed inlet is provided on the top of the tank 1, and a solenoid valve is installed at the feed inlet. The solenoid valve is electrically connected to the controller 15 to realize automatic feed control.

[0018] In this embodiment, the tank 1 has a discharge port at the bottom, and a one-way valve and a precision flow meter are installed at the discharge port to control the discharge speed of the filtered fuel and measure the output. A rotating drum 2 is installed inside the tank 1. Skeleton oil seal mechanical seals are installed at the upper and lower connections between the rotating drum 2 and the tank 1 to prevent methanol fuel leakage. The lower end of the rotating drum 2 passes through the lower end of the tank 1 and a drive source 13 is provided between the rotating drum 2 and the tank 1. The drive source 13 is a geared motor, and its output shaft is fixedly connected to the lower end of the rotating drum 2 through a coupling. The motor housing is detachably connected to the bottom of the tank 1 by bolts. The geared motor is steplessly speed-regulated by a controller 15 to adapt to the stirring intensity requirements under different impurity characteristics.

[0019] In this embodiment, the upper end of the rotating drum 2 passes through the upper part of the tank body 1 and a limiting component is provided between the tank body 1. The limiting component includes a limiting plate 7, which is located above the tank body 1. One end of the limiting plate 7 is installed on the rotating drum 2. A limiting bolt 8 is provided between the limiting plate 7 and the tank body 1. One end of the limiting bolt 8 passes through the limiting plate 7 and is inserted into the tank body 1. The limiting plate 7 is welded and fixed to the rotating drum 2. The limiting bolt 8 is a high-strength bolt, and its surface is galvanized for rust prevention.

[0020] See Figure 2 , Figure 3 As shown, a stirring plate 3 is provided on the outer ring of the rotating drum 2. The stirring plate 3 is made of wear-resistant ceramic composite material, with a smooth and wear-resistant surface, which avoids the material itself falling off and contaminating the fuel during the stirring process. The stirring plate 3 is rotatably mounted on the rotating drum 2 via a rotating shaft 4. An angle adjustment component is provided between the rotating shaft 4 and the rotating drum 2. The angle adjustment component includes a worm wheel 5, which is mounted on the rotating shaft 4. A worm 6 is meshed on one side of the worm wheel 5, and the worm 6 is rotatably mounted on the rotating drum 2.

[0021] See Figure 2 , Figure 4 As shown, the upper end of the worm gear 6 passes through the upper end of the rotating drum 2. The upper end of the worm gear 6 is hexagonal. A cap 14 is provided above the rotating drum 2, and the cap 14 is threadedly connected to the rotating drum 2. Both the worm gear 6 and the worm wheel 5 are located inside the rotating drum 2. A filter assembly is provided between two adjacent stirring plates 3. The filter assembly includes a filter plate 9, which is set in a multi-stage configuration. The upper filter plate 9 uses a 50-100 mesh filter screen to intercept large-diameter impurities; the lower layer uses a 200-300 mesh filter screen to intercept fine particles. The filter screen is made of stainless steel woven mesh, and its edges are welded and fixed to the fan-shaped plate frame to ensure that it is not easily deformed during filtration.

[0022] In this embodiment, multiple filter plates 9 are provided, and the multiple filter plates 9 are arranged in a fan shape. The filter plates 9 are evenly distributed around the axis of the rotating cylinder 2. A connecting plate 10 is installed on the side of the filter plates 9 that are close to each other. The connecting plate 10 is provided with a connecting hole 11. The connecting holes 11 on two adjacent connecting plates 10 are connected by fixing bolts. A support member is provided on the side of the filter plate 9 that is close to the rotating cylinder 2. The support member includes a limiting ring 12. The limiting ring 12 is installed on the rotating cylinder 2. The outer ring of the limiting ring 12 is provided with a groove. The filter plate 9 is slidably arranged with the groove. The other side of the filter plate 9 is connected to the tank body 1 by fixing bolts.

[0023] The implementation principle is as follows: Based on the density, particle size and other characteristics of impurities in methanol fuel, the initial position of the rotating drum 2 in the tank 1 is stabilized by the limiting plate 7 and the limiting bolt 8 to prevent the rotating drum 2 from rotating. First, the cap 14 on top of the rotating drum 2 is removed. The hexagonal head end of the worm 6 is rotated by the hexagonal wrench. The worm 6 meshes with the worm wheel 5 to drive the rotating shaft 4 to rotate, thereby adjusting the tilt angle of the stirring plate 3. After the adjustment is completed, the cap 14 is screwed back on to protect the internal structure. The methanol fuel to be processed is added into the tank 1 through the feed port of the tank 1, and the fuel is filled to the height covering the multi-layer filter components; the limit plug 8 is removed to release the restriction on the rotating drum 2, and the drive source 13 is started. The drive source 13 drives the rotating drum 2 to rotate inside the tank 1. The stirring plate 3 on the outer ring of the rotating drum 2 rotates synchronously with the rotating drum 2. The rotating stirring plate 3 stirs the fuel, so that the impurities in the fuel are evenly dispersed under the stirring action and then accelerate the sedimentation. During the stirring and sedimentation process, the filter components between the upper and lower adjacent stirring plates 3 work synchronously. When the sedimented impurities flow with the fuel through the filter plate 9, they are intercepted by the filter plate 9, thus achieving simultaneous sedimentation and filtration. The rotation speed of the drive source 13 is adjusted by the controller 15 on the front side of the tank 1, thereby controlling the rotation speed of the drum 2 and the stirring plate 3, and thus adjusting the stirring intensity to ensure that the impurity sedimentation efficiency matches the filtration rhythm of the filter components, so as to achieve precise control of the impurity treatment process. After the impurities have settled and the filtration is complete, turn off the drive source 13 and open the outlet of tank 1 to discharge the filtered clean methanol fuel. If it is necessary to clean the impurities or maintain the filter assembly, open the inspection door 16 on the rear side of tank 1, loosen the fixing bolts on the connecting plate 10, remove the filter plate 9 for cleaning or replacement, and reassemble the filter assembly after cleaning for reuse.
