Description

Technical Field

[0001] This invention relates to the field of steam explosion device technology, and more specifically to an automatic clamping device for steam explosion devices. Background Technology

[0002] Driven by dual-carbon goals and the demand for renewable energy, the biomass pretreatment market is experiencing steady growth. Steam explosion is one of the mainstream technologies for biomass pretreatment. Steam explosion, also known as vapor explosion, is a technology that uses the principle of steam ejection to achieve an explosion process for biomass pretreatment. Its essence is to instantaneously release steam molecules that have penetrated the plant tissue, converting the steam's internal energy into mechanical energy, which then acts on the intercellular layers of the biomass tissue, thus decomposing the raw material with less energy. Because it avoids the secondary pollution problems of chemical treatment and solves the problem of low efficiency in biological treatment, it is the most promising pretreatment technology in the field of biomass conversion. On the instantaneous explosion production line, a clamping device is needed to open or close the cage.

[0003] A patent with publication number CN121161641A is disclosed in the prior art. The solution includes a blasting vessel body, and a material cage is detachably installed inside the blasting vessel body. The material cage is installed inside the blasting vessel body by rotating around its axis through a material cage rotation structure. This solves the problem in the traditional technology that when the steam blasting vessel body is large, it is easy for the material to accumulate when it is full, resulting in poor material blasting effect. Moreover, the loading and unloading are more troublesome, which affects the material blasting efficiency.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, existing clamping structures rely on the friction of the clamps for gripping and transporting, which cannot be adapted to the structural design of the material cage to utilize the cage's own weight for gripping and transporting. This results in increased wear on structural components and a shortened service life.

[0006] Secondly, the existing cage cover structure requires manual assistance and cannot achieve fully automated opening and closing of the cage cover, which not only results in low work efficiency but also poses safety hazards.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0008] In view of the shortcomings of the existing technology, the present invention solves the problems of the traditional clamping cover structure, which uses the friction of the clamp to hold and transport the material, and cannot be combined with the structural design of the material cage to use the weight of the material cage itself for clamping and transport. This leads to increased wear on structural components and shortened service life. In addition, the existing material cage clamping cover structure requires manual assistance and cannot achieve fully automated opening and closing of the material cage cover, which not only has low work efficiency, but also poses safety hazards.

[0009] To address the above problems, the present invention provides the following technical solution:

[0010] An automatic clamping device for a steam explosion apparatus includes a plurality of radially sliding clamps, and a clamping area is formed by the region between the clamps. A material cage cover is provided within the clamping area, and a support body is rotatably mounted on the top of the material cage cover.

[0011] In the clamped state, the support body is supported on the upper ends of several grippers.

[0012] As an optimized solution, a material cage is inserted into the material cage cover, and a number of hinged anti-detachment claws are provided around the periphery of the material cage cover. In the clamping state, the claws abut against the anti-detachment claws of the material cage and open the anti-detachment claws of the material cage.

[0013] As an optimized solution, several of the grippers are connected to a mounting plate, which is connected to the frame, and the frame is movable.

[0014] As an optimized solution, a turntable is rotatably mounted on the mounting plate. The turntable has an asymptotic waist hole corresponding to each of the grippers. A vertical rod is vertically fixed to the upper end of the gripper, and a horizontal rod is horizontally fixed to the upper end of the vertical rod. A drive column that is slidably constrained within the asymptotic waist hole is fixed to the other end of the horizontal rod.

[0015] As an optimized solution, in the clamped state, the several grippers close together in a circular shape.

[0016] As an optimized solution, the support body includes support legs arranged in a cross shape, the radial length of which is greater than the diameter of the material cage cover.

[0017] As an optimized solution, a drive gear is rotatably mounted on the frame, and a driven gear that meshes with the drive gear is fixedly connected to the turntable.

[0018] As an optimized solution, a power source is fixedly connected to the frame, and the output end of the power source is connected to the drive gear.

[0019] As an optimized solution, the frame includes a top plate and a bottom plate arranged side by side from top to bottom, and the top plate, bottom plate and mounting plate are fixed together by a number of double-ended screws.

[0020] As an optimized solution, the top plate, bottom plate, and mounting plate are arranged in a cross or star shape.

[0021] As an optimized solution, a rubber strip is fixed on the inner wall of the gripper.

[0022] As an optimized solution, an annular groove is provided on the outer wall of the material cage, and the anti-detachment claw of the material cage is engaged in the annular groove.

[0023] As an optimized solution, the material cage cover is provided with avoidance holes to avoid the anti-detachment claws of the material cage.

[0024] As an optimized solution, the hinge position of the anti-detachment claw of the material cage is provided with a torsion spring to prevent the clamping force between the claw and the annular groove.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] It can achieve fully automated opening and closing of material cage covers, which facilitates material loading and unloading without manual assistance, improving work efficiency while overcoming safety hazards;

[0027] By designing the cage cover, the material cage can be clamped and transported using its own weight, rather than by the friction of the clamps. This greatly reduces the wear of structural components, extends service life, and the design is simple, easy to maintain and replace. Attached Figure Description

Detailed Implementation

[0036] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0037] like Figures 1 to 6 As shown, the automatic clamping device for the steam explosion apparatus includes several radially sliding clamps 1, forming a clamping area between the clamps 1. A material cage cover 14 is provided within the clamping area, and a support is rotatably mounted on the top of the material cage cover 14.

[0038] In the clamped state, the support body is supported on the upper ends of several grippers 1.

[0039] A material cage 17 is inserted inside the material cage cover 14. Several hinged anti-detachment claws 15 are provided around the perimeter of the material cage cover 14. When the material cage cover 14 is clamped, the claw 1 abuts against the anti-detachment claws 15 and opens the anti-detachment claws 15.

[0040] Several grippers 1 are connected to the mounting plate 2, which is connected to the frame, and the frame is movable.

[0041] A turntable 18 is rotatably mounted on the mounting plate 2. Each gripper 1 has an asymptotic waist hole 13. A vertical rod 10 is vertically fixed to the upper end of the gripper 1. A horizontal rod 11 is horizontally fixed to the upper end of the vertical rod 10. A drive column 12 that is slidably constrained in the asymptotic waist hole 13 is fixed to the other end of the horizontal rod 11.

[0042] A guide structure, such as a slide rail, can be provided between the crossbar 11 and the mounting plate 2 to assist the crossbar 11 in moving radially.

[0043] When clamped, several grippers 1 close together in a circular shape to ensure that each material cage anti-detachment gripper 15 can be pressed tightly.

[0044] The support includes a cross-shaped support leg 16, the radial length of which is greater than the diameter of the cage cover 14.

[0045] The frame is equipped with a drive gear 8 that rotates, and the turntable 18 is fixedly connected with a driven gear 9 that meshes with the drive gear 8.

[0046] A power source 7 is fixedly connected to the frame, and the output end of the power source 7 is connected to the drive gear 8.

[0047] The frame includes a top plate 4 and a bottom plate 3 arranged side by side from top to bottom. The top plate 4, the bottom plate 3 and the mounting plate 2 are fixed together by a number of double-headed screws 5, which can facilitate replacement and assembly.

[0048] The top plate 4, bottom plate 3, and mounting plate 2 are arranged in a cross or star shape with a hollow design, which can reduce the overall weight.

[0049] A mounting base 6 is fixedly connected to the base plate 3, and the mounting base 6 is connected to the mobile device to drive the frame to move.

[0050] A rubber strip is fixed on the inner wall of the gripper 1 to provide cushioning and prevent the gripper 1 from making hard contact with the anti-detachment gripper 15 of the material cage.

[0051] An annular groove is provided on the outer wall of the material cage 17, and the material cage anti-detachment claw 15 is engaged in the annular groove.

[0052] The material cage cover 14 is provided with a clearance hole to avoid the material cage anti-detachment claw 15.

[0053] The hinge position of the anti-detachment claw 15 of the material cage is equipped with a torsion spring to maintain the clamping force between the anti-detachment claw 15 of the material cage and the annular groove.

[0054] The working principle of this device is as follows:

[0055] When the cover is open, the power source 7 drives the drive gear 8, which in turn drives the driven gear 9 to reduce speed and increase torque. This allows for the selection of a low-torque, low-power motor, thus reducing costs.

[0056] Because the turntable 18 connected to the driven gear 9 has an asymptotic waist hole 13, and one end of the crossbar 11 is fixedly connected to a drive column 12 that is slidably constrained within the asymptotic waist hole 13, as the position of the asymptotic waist hole 13 changes, the crossbar 11 moves radially, thereby causing the gripper 1 to tighten. Since the radial length of the support foot 16 is greater than the diameter of the material cage cover 14, the support foot 16 enters the space between the gripper 1 and the mounting plate 2, thus achieving suspension support of the support foot 16 using the upper end of the gripper 1. The cage cover 14 can be hung on the gripper 1, and at the same time, the lower end of the gripper 1 presses against the cage anti-detachment claw 15 and opens the cage anti-detachment claw 15. At this time, the cage cover 14 can be opened upward. This realizes the use of the cage 17's own weight for clamping and transportation, instead of using the friction of the clamp, which greatly reduces the wear of structural components, extends service life, and realizes fully automated opening and closing of the cage cover 14, which is convenient for loading and unloading materials without manual assistance. This improves work efficiency and overcomes safety hazards.

[0057] When the lid is closed (in the open state), the power source 7 drives the drive gear 8 to rotate in the opposite direction.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
