Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, and specifically to a reaction vessel with automatic feeding and weighing function. Background Technology

[0002] Reactors are core reaction equipment in process industries such as chemical, pharmaceutical, and food processing. The accuracy and stability of material addition directly determine product quality, production safety, and raw material utilization. To improve automation, weighing modules are installed on the reactor legs to indirectly measure the amount of material added by monitoring changes in total weight. Weighing equipment with anti-tipping capabilities is widely used, mainly consisting of an upper plate, lower plate, bending plate, force transmission mechanism, transport plate, pads, and sensors. The transport plate protects the equipment during transportation and installation and is removed when the equipment is in use, allowing it to be in a state of stress deformation.

[0003] Since most reactors are equipped with stirring devices, they generate horizontal vibrations during operation. These horizontal vibrations, during dynamic load bearing, apply a lateral force to the weighing module. This affects the accuracy of the weighing module and generates additional vibration loads on its various components, accelerating fatigue damage and shortening the equipment's lifespan. Summary of the Invention

[0004] This invention provides a reaction vessel with automatic feeding and weighing function to solve the above-mentioned problems.

[0005] The present invention provides a reaction vessel with automatic feeding and weighing function, which adopts the following technical solution: a reaction vessel with automatic feeding and weighing function includes a vessel body; multiple support legs are fixed at the lower end of the vessel body; a weighing module is provided between the support legs and the ground; the weighing module includes a lower plate, an upper plate, and a vibration damping device.

[0006] The lower plate is fixed to the ground at the front and rear; a pressure sensor is installed on the lower plate; the rear end of the pressure sensor is fixed to the lower plate by a pad, and the front end is suspended between the lower plate and the pressure sensor; a pressure head is fixed to the upper end of the pressure sensor.

[0007] The upper plate is located above the pressure head and abuts against the pressure head; the pressure sensor is used to detect the pressure between the pressure head and the upper plate; a bending plate is provided below the upper plate; the bending plate is a U-shaped plate with the opening facing upward; the middle section of the bending plate is located between the front end and the lower plate, and both ends are fixedly connected to the upper plate; during installation, the upper plate and the lower end of the support leg abut against each other and are fixed.

[0008] Two vibration damping devices are provided, distributed on both sides of the bent plate. Each device includes a telescopic rod and a lever. The lever is positioned at the front and rear, with its middle section rotatably mounted on the lower plate via a support assembly around a vertical axis. An inner cylinder is fixed to the rear end of the lever. The front end of the lever is rotatably mounted on the bent plate via a rotating assembly around a vertical axis. The telescopic rod, located behind the lever, includes a mother cylinder and a daughter rod. The mother cylinder is located behind the daughter rod and slides with it. The mother cylinder is rotatably mounted on the lower plate via a column. An outer cylinder with a vertically aligned axis is fixed to the front end of the daughter rod. The outer cylinder is fitted onto the upper end of the inner cylinder and rotatably engages with it. A damping assembly is provided between the daughter rod and the mother cylinder, providing damping for the relative sliding between them. When the vessel body experiences horizontal vibration, the upper plate generates a small horizontal amplitude relative to the lower plate. This amplitude is amplified by the lever driving the telescopic rod to extend and retract, thus amplifying the extension and retraction of the upper plate. The damping assembly within the telescopic rod then effectively dissipates energy, improving the vibration damping effect.

[0009] Furthermore, an auxiliary component is provided on the lower plate; during transportation and installation, the auxiliary component is used to limit the rotation of the lever and telescopic rod to limit the upper plate.

[0010] Furthermore, the auxiliary components include an auxiliary frame and an auxiliary rod; the auxiliary frame is fixed to the lower plate; the auxiliary rod is vertically positioned and threaded into the auxiliary frame; two nuts are threaded onto the auxiliary rod; during transportation and installation, the lower end of the auxiliary rod passes through the outer and inner cylinders, with the two nuts distributed on the upper and lower sides of the outer cylinder. The lower nut abuts against the inner cylinder, and the upper nut abuts against the outer cylinder, thereby limiting the rotation of the lever and telescopic rod to limit the movement of the upper plate; after installation, the lower end of the auxiliary rod is moved up to above the inner and outer cylinders, and the lower nut is screwed onto the auxiliary rod to prevent loss. Compared to existing technologies that insert a transport plate between a bent plate and a lower plate to prevent the upper plate from swaying during transportation and installation, and then fix the transport plate to the lower plate with multiple bolts, this new method allows for the use of an auxiliary rod that passes through the outer and inner cylinders when the upper plate needs to be restricted. Two nuts are located on the upper and lower sides of the outer cylinder, with the lower nut abutting against the inner cylinder and the upper nut abutting against the outer cylinder. After installation, simply remove the lower nut and rotate the auxiliary rod upwards to disengage it from the outer and inner cylinders. Then, screw the lower nut onto the auxiliary rod to release the restriction on the upper plate. This reduces the number of operation steps and avoids the loss of the limiting parts when the upper plate needs to be restricted later.

[0011] Furthermore, a limiting screw is provided between the front end of the bending plate and the lower plate; a limiting ring is fixed at the upper end of the limiting screw, the limiting ring is located above the bending plate, and there is an movable gap between the limiting screw and the bending plate; the lower end of the limiting screw passes through the bending plate and is threadedly connected to the lower plate.

[0012] Furthermore, the rotating assembly includes a lug and a mounting ring.

[0013] The lug is fixed to the bent plate; the lug has a connecting hole; the mounting ring axis is vertically fixed to the front end of the lever; the mounting ring has a rotating screw connected to its internal thread.

[0014] The inner wall of the mounting ring is provided with an annular receiving groove; there is an extension gap between the lower groove wall of the receiving groove and the rotating screw; a top ring is coaxially provided in the receiving groove; the top ring is fixed to the outside of the rotating screw, and a top cylinder is provided on the side of the top ring near the hanging ear; the top cylinder is coaxially provided in the extension gap and is fixedly connected to the top ring; during transportation and installation, the top cylinder and the hanging ear abut against each other; after installation, the rotating screw is turned to drive the top cylinder away from the hanging ear.

[0015] Furthermore, the mounting ring of the rotating component corresponding to one vibration damping device is located above the hanging lug, while the mounting ring of the rotating component corresponding to the other vibration damping device is located below the hanging lug. This is used to limit the amplitude of the upper plate's tilting and swaying.

[0016] Furthermore, the support assembly includes a slider; the slider is slidably mounted on the lower plate via a groove; a support column is rotatably mounted on the upper end of the slider; a sliding hole is provided on the side wall of the support column; the lever and the sliding hole are slidably engaged; a locking structure is provided between the slider and the lower plate; the locking structure is used to lock the sliding between the slider and the lower plate. Driving the slider to slide within the groove moves the slider to a suitable position to adjust the lever arm between the lever and the support column, thereby adjusting the accuracy of vibration damping.

[0017] Furthermore, the locking structure includes a locking screw; the locking screw slides into the lower plate and is threadedly connected to the slider. After the slider is moved to the appropriate position to adjust the lever arm between the lever and the support, the locking screw is turned to press the slider against the groove.

[0018] Furthermore, the damping assembly includes a piston plate and an adjustment structure; the piston plate is slidably installed inside the mother cylinder; the piston plate and the rod are fixedly connected; the piston plate divides the mother cylinder into a front chamber and a rear chamber; both the front and rear chambers are filled with damping fluid; a damping hole is formed on the piston plate; the damping hole connects the front and rear chambers; the lever support is set to be adjustable, and the size of the damping hole is adjusted by the adjustment structure according to the position of the support on the lower plate, so that the energy dissipation capacity of the damping assembly is matched with the vibration amplitude, avoiding exceeding the stroke of the damping assembly and causing cylinder explosion.

[0019] Furthermore, the adjustment structure includes a hydraulic chamber and a hydraulic port.

[0020] The hydraulic chamber is located inside the piston plate; an adjusting block is provided inside the hydraulic chamber; the adjusting block and the hydraulic chamber slide in a sealed manner; an adjusting hole is provided on the adjusting block; the adjusting hole and the damping hole coincide and are connected; the hydraulic chamber is filled with hydraulic oil.

[0021] The hydraulic hole is located inside the lower plate; the hydraulic hole axis is positioned front and rear; a piston rod is slidably mounted inside the hydraulic hole; the hydraulic hole is filled with hydraulic oil; the piston rod and the slider are fixedly connected; the hydraulic hole and the hydraulic chamber are connected by an oil pipe. When the slider slides on the lower plate, the piston rod moves synchronously and forces the hydraulic oil in the hydraulic hole into the hydraulic chamber, or draws the hydraulic oil in the hydraulic chamber into the hydraulic hole, driving the adjusting block to slide, thereby adjusting the degree of overlap between the damping hole and the adjusting hole, adjusting the ability of damping fluid to pass through the damping hole, and thus adjusting the damping effect of the damping assembly, so that the energy dissipation capacity of the damping assembly is matched with the vibration amplitude, avoiding exceeding the stroke of the damping assembly and causing cylinder explosion.

[0022] The beneficial effects of this invention are: when the vessel body generates horizontal vibration, the upper plate generates a small horizontal amplitude relative to the lower plate, which drives the telescopic rod to extend and retract through the lever, and transmits the small amplitude of the upper plate to the telescopic rod to amplify the extension and retraction amount, thereby achieving sufficient and effective energy dissipation through the damping component inside the telescopic rod, and improving the vibration reduction effect.

[0023] Furthermore, compared to the existing technology where a transport plate is inserted between the bending plate and the lower plate to prevent the upper plate from shaking during transportation and installation, and the transport plate is fixed to the lower plate with multiple bolts, when it is necessary to restrict the movement of the upper plate, the lower end of the auxiliary rod passes through the outer cylinder and the inner cylinder, and two nuts are distributed on the upper and lower sides of the outer cylinder. The lower nut abuts against the inner cylinder, and the upper nut abuts against the outer cylinder. After installation, it is only necessary to remove the lower nut and turn the auxiliary rod upward to disengage the auxiliary rod from the outer cylinder and the inner cylinder, and then screw the lower nut onto the auxiliary rod to release the restriction on the upper plate. This reduces the number of operation steps and avoids the loss of the limiting parts when the upper plate needs to be limited later.

[0024] Furthermore, the lever support is made adjustable. The size of the damping hole is adjusted by adjusting the structure according to the position of the support on the lower plate, so that the energy dissipation capacity of the damping component is matched with the vibration amplitude, thus avoiding the cylinder explosion caused by exceeding the stroke of the damping component.

[0041] An embodiment of the reaction vessel with automatic feeding and weighing function of the present invention, such as... Figures 1 to 13 As shown: It includes a vessel body 100; multiple support legs are fixed at the lower end of the vessel body 100; a weighing module is provided between the support legs and the ground; the weighing module includes a lower plate 200, an upper plate 300, and a vibration damping device.

[0044] Two vibration damping devices are provided, distributed on both sides of the bent plate 310. Each device includes a telescopic rod 500 and a lever 700. The lever 700 is positioned front and rear, and its middle part is rotatably mounted on the lower plate 200 via a support assembly around a vertical axis. The support assembly includes a slider 810. The slider 810 is slidably mounted on the lower plate 200 via a slide groove. A support column 820 is rotatably mounted on the upper end of the slider 810. A sliding hole is provided on the side wall of the support column 820. The lever 700 and the slide hole are in sliding engagement. A locking structure is provided between the slider 810 and the lower plate 200. The locking structure is used to lock the sliding between the slider 810 and the lower plate 200. Driving the slider 810 to slide within the slide groove moves it to a suitable position to adjust the lever arm between the lever 700 and the support column 820, thereby adjusting the accuracy of vibration damping. The locking structure includes a locking screw 830. The locking screw 830 is in sliding engagement with the lower plate 200 and threadedly connected to the slider 810. After the slider 810 is moved to the appropriate position to adjust the lever arm between the lever 700 and the support 820, the locking screw 830 is turned to press the slider 810 against the groove.

[0045] The lever 700 has an inner cylinder 710 fixed to its rear end; the lever 700 has its front end mounted on a bent plate 310 via a rotating assembly that rotates around a vertical axis; the rotating assembly includes a lug 910 and a mounting ring 920.

The mounting ring 920 of the rotating component corresponding to one vibration damping device is above the hanging ear 910, and the mounting ring 920 of the rotating component corresponding to another vibration damping device is below the hanging ear 910. This is used to limit the amplitude of the upper plate 300 tilting and swinging.

[0046] The telescopic rod 500 is located behind the lever 700 and includes a mother cylinder 510 and a son rod 520. The mother cylinder 510 is located behind the son rod 520 and slides with it. The mother cylinder 510 is rotatably mounted on the lower plate 200 via a column. An outer cylinder 521 with a vertically oriented axis is fixed to the front end of the son rod 520. The outer cylinder 521 is fitted onto the upper end of the inner cylinder 710 and rotatably engages with it. A damping assembly is provided between the son rod 520 and the mother cylinder 510. The damping assembly provides damping for the relative sliding between the son rod 520 and the mother cylinder 510. When the vessel body 100 generates horizontal vibration, the upper plate 300 generates a small horizontal amplitude relative to the lower plate 200. The lever 700 drives the telescopic rod 500 to extend and retract, and transmits the small amplitude of the upper plate 300 to the telescopic rod 500, amplifying the extension and retraction. This allows for sufficient and effective energy dissipation through the damping assembly within the telescopic rod 500, improving the vibration reduction effect.

[0047] The damping assembly includes a piston plate 600 and an adjusting structure. The piston plate 600 is slidably installed inside the mother cylinder 510. The piston plate 600 and the rod 520 are fixedly connected. The piston plate 600 divides the mother cylinder 510 into a front chamber and a rear chamber. Both the front and rear chambers are filled with damping fluid. A damping hole 610 is provided on the piston plate 600, connecting the front and rear chambers. The support column 820 of the lever 700 is adjustable. Based on the position of the support column 820 on the lower plate 200, the size of the damping hole 610 is adjusted by the adjusting structure to match the energy dissipation capacity and vibration amplitude of the damping assembly, preventing the damping assembly from exceeding its stroke and causing cylinder failure. The adjusting structure includes a hydraulic chamber 620 and a hydraulic hole 650. A hydraulic chamber 620 is located within the piston plate 600; an adjusting block 630 is provided within the hydraulic chamber 620; the adjusting block 630 and the hydraulic chamber 620 slide in a sealed manner; an adjusting hole 631 is provided on the adjusting block 630; the adjusting hole 631 coincides with and communicates with the damping hole 610; the hydraulic chamber 620 is filled with hydraulic oil. A hydraulic hole 650 is located within the lower plate 200; the hydraulic hole 650 is positioned along its axis front and rear; a piston rod 640 is slidably mounted within the hydraulic hole 650; the hydraulic hole 650 is filled with hydraulic oil; the piston rod 640 and the slider 810 are fixedly connected; the hydraulic hole 650 and the hydraulic chamber 620 are connected by an oil pipe.

[0048] When the slider 810 slides on the lower plate 200, the piston rod 640 moves synchronously and presses the hydraulic oil in the hydraulic hole 650 into the hydraulic chamber 620, or draws the hydraulic oil in the hydraulic chamber 620 into the hydraulic hole 650, driving the adjusting block 630 to slide, thereby adjusting the degree of overlap between the damping hole 610 and the adjusting hole 631, adjusting the ability of damping fluid to pass through the damping hole 610, thereby adjusting the damping effect of the damping assembly, so that the energy dissipation capacity of the damping assembly is matched with the vibration amplitude, and avoiding the cylinder explosion caused by exceeding the stroke of the damping assembly.

[0049] An auxiliary component is provided on the lower plate 200. During transportation and installation, the auxiliary component is used to limit the rotation of the lever 700 and the telescopic rod 500, thereby limiting the upper plate 300. The auxiliary component includes an auxiliary frame 210 and an auxiliary rod 220. The auxiliary frame 210 is fixed on the lower plate 200. The auxiliary rod 220 is vertically set and threadedly engaged with the auxiliary frame 210. Two nuts are threadedly connected to the auxiliary rod 220. During transportation and installation, the lower end of the auxiliary rod 220 passes through the outer cylinder 521 and the inner cylinder 710. The two nuts are distributed on the upper and lower sides of the outer cylinder 521. The lower nut abuts against the inner cylinder 710, and the upper nut abuts against the outer cylinder 521 to limit the rotation of the lever 700 and the telescopic rod 500, thereby limiting the upper plate 300. After installation, the lower end of the auxiliary rod 220 is moved up above the inner cylinder 710 and the outer cylinder 521, and the lower nut is screwed onto the auxiliary rod 220 to prevent loss. Compared to the existing technology, which inserts a transport plate between the bending plate 310 and the lower plate 200 to prevent the upper plate 300 from shaking during transportation and installation, and fixes the transport plate to the lower plate 200 with multiple bolts, when it is necessary to restrict the movement of the upper plate 300, the lower end of the auxiliary rod 220 passes through the outer cylinder 521 and the inner cylinder 710. Two nuts are distributed on the upper and lower sides of the outer cylinder 521. The lower nut abuts against the inner cylinder 710, and the upper nut abuts against the outer cylinder 521. After installation, it is only necessary to remove the lower nut and turn the auxiliary rod 220 upward to disengage the auxiliary rod 220 from the outer cylinder 521 and the inner cylinder 710, and then screw the lower nut onto the auxiliary rod 220 to release the restriction on the upper plate 300. This reduces the number of operation steps and avoids the loss of the limiting parts when it is necessary to limit the movement of the upper plate 300 later.

[0050] Based on the above embodiments, the usage principle and working process of the present invention are as follows: During transportation and installation, such as Figure 1 and Figure 2 As shown, the lower end of the auxiliary rod 220 passes through the outer cylinder 521 and the inner cylinder 710. Two nuts are distributed on the upper and lower sides of the outer cylinder 521. The lower nut abuts against the inner cylinder 710, and the upper nut abuts against the outer cylinder 521 to limit the rotation of the lever 700 and the telescopic rod 500, thereby limiting the upper plate 300. The top cylinder 932 abuts against the hanging lug 910. After installation, as shown... Figure 13As shown, turning the rotating screw 911 drives the top cylinder 932 away from the hanging lug 910. Turning the auxiliary rod 220 drives the lower end of the auxiliary rod 220 to move upward above the inner cylinder 710 and the outer cylinder 521, and screwing the lower nut onto the auxiliary rod 220 to prevent it from being lost. Compared to the existing technology, which inserts a transport plate between the bending plate 310 and the lower plate 200 to prevent the upper plate 300 from shaking during transportation and installation, and fixes the transport plate to the lower plate 200 with multiple bolts, when it is necessary to restrict the movement of the upper plate 300, the lower end of the auxiliary rod 220 passes through the outer cylinder 521 and the inner cylinder 710. Two nuts are distributed on the upper and lower sides of the outer cylinder 521. The lower nut abuts against the inner cylinder 710, and the upper nut abuts against the outer cylinder 521. After installation, it is only necessary to remove the lower nut and turn the auxiliary rod 220 upward to disengage the auxiliary rod 220 from the outer cylinder 521 and the inner cylinder 710, and then screw the lower nut onto the auxiliary rod 220 to release the restriction on the upper plate 300. This reduces the number of operation steps and avoids the loss of the limiting parts when it is necessary to limit the movement of the upper plate 300 later. When the vessel body 100 generates horizontal vibration, the upper plate 300 generates a small horizontal amplitude relative to the lower plate 200. The lever 700 drives the telescopic rod 500 to extend and retract, and the small amplitude of the upper plate 300 is transmitted to the telescopic rod 500 to amplify the extension and retraction. Thus, the damping component inside the telescopic rod 500 achieves sufficient and effective energy dissipation and improves the vibration reduction effect.

[0051] Meanwhile, the support column 820 of the lever 700 is set to be adjustable. Based on the position of the support column 820 on the lower plate 200, the size of the damping hole 610 is adjusted via an adjustment structure to match the energy dissipation capacity of the damping assembly with the vibration amplitude. Specifically, when the slider 810 slides on the lower plate 200, the piston rod 640 moves synchronously, pressing the hydraulic oil in the hydraulic hole 650 into the hydraulic chamber 620, or drawing the hydraulic oil in the hydraulic chamber 620 into the hydraulic hole 650, driving the adjusting block 630 to slide. This adjusts the overlap between the damping hole 610 and the adjusting hole 631, regulating the flow of damping fluid through the damping hole 610, thereby adjusting the damping effect of the damping assembly. This ensures that the energy dissipation capacity of the damping assembly matches the vibration amplitude, preventing the damping assembly from exceeding its stroke and causing cylinder failure.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
