Description
Technical Field
[0001] This invention relates to the field of drum forming technology, specifically to an auxiliary device for the integrated forming of a straight conical drum for a horizontal screw centrifuge. Background Technology
[0002] A horizontal screw centrifuge is short for horizontal screw discharge sedimentation centrifuge. It mainly consists of a high-speed rotating drum, a screw rotating in the same direction but at a different speed, and a differential gear. After the material to be separated enters the inner cavity of the drum, a strong centrifugal force is generated within the high-speed rotating drum. The denser solid particles in the material experience a greater centrifugal force and are thrown to adhere to the inner wall of the drum, forming a solid ring layer. The lighter phase (liquid) experiences a smaller centrifugal force and can only form a liquid ring layer inside the solid ring layer. Because the screw and drum move in the same direction but at different speeds under the action of the differential gear, the solid particles deposited on the inner wall of the drum are pushed towards the discharge port at the smaller end of the drum and discharged. The liquid is discharged from the overflow port at the other end of the drum through the spiral channel formed by the screw blades.
[0003] The rotating drum is one of the core components of a horizontal screw centrifuge. It generates powerful centrifugal force through high-speed rotation, causing solid particles in the suspension to settle rapidly, achieving solid-liquid separation. The drum typically consists of a cylindrical and a conical cylinder. It is usually constructed by dividing the cylinder and conical cylinder into two parts, molding them separately, and then connecting them by welding and bolting. However, in practical use, this method has been found to result in numerous welds and requires a large amount of forging material, leading to high costs. Some technologies use mold casting for integrated molding, which requires support equipment to maintain the stability of the mold during injection. However, due to the different specifications of the drums, it is difficult to effectively support molds of different specifications. Different equipment needs to be used when molding drums of different specifications. Therefore, an auxiliary device for integrated molding of a straight conical drum for a horizontal screw centrifuge is proposed. Summary of the Invention

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1: Please refer to the following: Figures 1-8 This invention provides a technical solution: an auxiliary device for integral molding of a straight conical drum of a horizontal screw centrifuge, comprising a base 100, multiple first adjustment components, multiple second adjustment components, and multiple third adjustment components. The first adjustment components are arranged in a circumferential array above the base 100, and the device supports conical cylinder molds of different diameters of the drum through the first adjustment components. The second adjustment components are located above the first adjustment components, and the device supports conical cylinder molds of different tilt angles of the drum through the second adjustment components. The third adjustment components are located on one side of the second adjustment components, and the device supports cylindrical molds of different diameters of the drum through the third adjustment components.
[0020] Please refer to the following: Figures 1-8The present invention provides a technical solution: the first adjustment component includes a support base 200, an adjustment base 201, and a fixed base 202. The support base 200 is fixedly connected to the top outer surface of the fixed base 202, and the adjustment base 201 is movably inserted into the top outer surface of the support base 200. A waist hole 700 is provided on the outer surface of the base 100, and a connecting hole is provided on the outer surface of the fixed base 202. A positioning bolt 701 is inserted into the waist hole 700 and the connecting hole, and a positioning nut 702 is threaded onto the outer surface of the positioning bolt 701. Specifically, the overall size of the device is adjusted according to different specifications of injection molds. By unscrewing the positioning nut 702, the positioning nut 702 is disengaged from the surface of the positioning bolt 701, thereby releasing the restriction between the fixed seat 202 and the base 100. This allows the fixed seat 202 to slide within the waist hole 700 on the base 100. According to the scale lines on the base 100, the position of the support seat 200 is adjusted to match the size of the drum mold. After adjustment, the positioning bolt 701 is inserted into the connecting hole, and then the positioning nut 702 is screwed into the surface of the positioning bolt 701, thereby fixing the fixed seat 202. This allows for the support and shaping of drums with different conical cylinder diameters.
[0021] As a further explanation of the present invention, a fixing cylinder is fixedly connected to the bottom outer surface of the adjusting seat 201. The fixing cylinder is movably inserted into the inside of the support seat 200. A fixing bolt is threaded through the outer surface of the support seat 200. A plurality of fixing screw holes arranged in a linear array are opened on the outer surface of the fixing cylinder. The fixing bolt is threadedly connected to the inside of one of the fixing screw holes. Specifically, by unscrewing the fixing bolt, the fixing bolt is disengaged from the inside of the fixing screw hole, and the position of the fixing cylinder inside the support seat 200 is adjusted, thereby adjusting the height between the adjusting seat 201 and the support seat 200. This makes the device suitable for supporting drum molds with conical sections of different heights.
[0022] Example 2: Please refer to the following: Figures 1-8The present invention provides a technical solution: the second adjustment component includes a rotating seat 300 fixed to the top outer surface of the adjustment base 201, a support shaft 301 rotatably passing through the outer surface of the rotating seat 300, a tapered support plate 302 sleeved on the outer surface of the support shaft 301, a gear 400 sleeved on the outer surface of the support shaft 301, a rack 401 movably meshing with the outer surface of the gear 400, an arc-shaped plate 402 fixedly connected to the top outer surface of the rack 401, an extension plate 403 fixedly connected to the side of the fixed base 202, and an adjustment plate fixedly connected to the side of the arc-shaped plate 402, one of the adjustment plates... An adjusting screw 404 is threaded through the outer surface of the plate. The other end of the adjusting screw 404 is rotatably connected to the outer surface of one of the extension plates 403. Specifically, by rotating the adjusting screw 404, the adjusting screw 404 drives the arc plate 402 to move, which in turn drives the rack 401 to move. The rack 401 meshes with the gear 400, which drives the support shaft 301 to rotate, thereby adjusting the tilt angle between the conical support plate and the rotating seat 300 so that it is consistent with the tilt angle between the conical end and the vertical section of the conical cylinder. This allows the drum with different conical cylinder tilt angles to be supported and shaped.
[0023] As a further explanation of the present invention, a first expansion plate 800 is movably inserted between two adjacent arc-shaped plates 402. Specifically, when the adjusting screw 404 is rotated to move one of the arc-shaped plates 402, the arc-shaped plate 402 moves the first expansion plate 800, causing multiple arc-shaped plates 402 to move simultaneously, thereby causing multiple racks 401 to move simultaneously, thereby simultaneously adjusting the angle of the tapered support plate 302. Furthermore, when adjusting the position between multiple adjusting seats 201, the curvature of the arc-shaped plate 402 changes, causing the surface of the first expansion plate 800 to move.
[0024] As a further explanation of the present invention, multiple extension plates 403 are fixedly connected to slide rods on their outer surfaces, and multiple adjustment plates are respectively sleeved on the outer surfaces of multiple slide rods. Specifically, when the adjustment screw 404 is rotated, one of the adjustment plates drives the arc plate 402 to move, causing the other adjustment plates to slide on the outer surface of the slide rods, so that the adjustment plates move in a stable linear motion.
[0025] Example 3: Please refer to the following: Figures 1-8The present invention provides a technical solution: a tapered support plate 302 includes a tapered fixed plate 600 and a tapered movable plate 601. The tapered movable plate 601 is movably inserted inside the tapered fixed plate 600. A lateral support plate is provided on one side of the tapered movable plate 601. The lateral support plate includes a lateral fixed plate 500 and a lateral movable plate 501. The lateral movable plate 501 is movably inserted inside the lateral support plate. The lateral movable plate 501 is rotatably disposed on one side of the tapered movable plate 601 via a damping shaft. A third adjustment component includes a limiting bolt 603. The limiting bolt 603 is threaded through the outer surface of the tapered fixed plate 600. The outer surface of the tapered movable plate 601 has a plurality of linearly arrayed... The limiting screw hole 602 is set, and the limiting bolt 603 is connected to the internal thread of one of the limiting screw holes 602. Specifically, the position of the side support plate is adjusted according to the diameter of the vertical cylinder. At this time, the limiting bolt 603 is unscrewed, so that the limiting bolt 603 is disengaged from the inside of the limiting screw hole 602. The position of the tapered movable plate 601 in the tapered fixed plate 600 is adjusted, thereby adjusting the relative length of the tapered movable plate 601 and the tapered fixed plate 600, thereby adjusting the length of the tapered support plate. After adjusting the length of the tapered support plate, it will drive the tapered support plate to move, so that the diameter of the multiple tapered support plates is adapted to the vertical cylinder, thereby supporting the drum mold with different cylinder diameters.
[0026] As a further explanation of the present invention, both sides of the lateral fixing plate 500 are fixedly connected to the fixing side plate 900, and the second expansion plate 901 is movably inserted between two adjacent fixing side plates 900. Specifically, when the position of the lateral support plate is adjusted, the multiple lateral fixing plates 500 will move, which causes the second expansion plate 901 to move inside the fixing side plate 900, thereby enabling the position of multiple lateral support plates to be moved simultaneously.
[0027] The first expansion plate 800 and the second expansion plate 901 are each composed of multiple expansion blocks that are hinged to each other, so that when the curvature of the arc plate 402 and the lateral fixing plate 500 changes, the first expansion plate 800 and the second expansion plate 901 can move stably inside the arc plate 402 and the lateral fixing plate 500, respectively.
[0028] Working principle: When using this invention, the overall size of the device is adjusted according to the injection mold of different specifications. At this time, by unscrewing the positioning nut 702, the positioning nut 702 is disengaged from the surface of the positioning bolt 701, thereby releasing the restriction between the fixed seat 202 and the base 100, allowing the fixed seat 202 to slide in the waist hole 700 on the base 100. According to the scale line on the base 100, the position of the support seat 200 is adjusted to match the size of the drum mold. After the adjustment is completed, the positioning bolt 701 is inserted into the connecting hole, and then the positioning nut 702 is screwed into the surface of the positioning bolt 701, thereby fixing the fixed seat 202, so as to support and form drums with different conical cylinder diameters. By rotating the adjusting screw 404, the adjusting screw 404 drives the arc plate 402 to move, which in turn drives the rack 401 to move. The rack 401 meshes with the gear 400, which drives the support shaft 301 to rotate, thereby adjusting the inclination angle between the conical support plate and the rotating seat 300 so that it is consistent with the inclination angle between the conical end and the vertical section of the conical cylinder. This allows for the support and shaping of drums with different inclination angles of the conical cylinder section. Then, adjust the position of the lateral support plate according to the diameter of the vertical cylinder. At this time, unscrew the limit bolt 603 so that the limit bolt 603 disengages from the inside of the limit screw hole 602. Adjust the position of the conical movable plate 601 within the conical fixed plate 600, thereby adjusting the relative length of the conical movable plate 601 and the conical fixed plate 600, and thus adjusting the length of the conical support plate. After adjusting the length of the conical support plate, it will drive the conical support plate to move, so that the diameter of the multiple conical support plates is adapted to the vertical cylinder, thereby supporting the drum mold with different cylinder diameters.
[0029] After adjustment, the mold is fixed to the inner wall of the device, and injection molding is performed through the injection mold to form the drum in one piece.
[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
