Description

Technical Field

[0001] This invention relates to the field of dredging tooling technology, and more specifically to the field of tooling technology for opening holes in the buffer tank of a waste gas scrubbing tower. Background Technology

[0002] With the rapid development of the polysilicon industry, it is increasingly favored by the new energy sector. However, waste gas is inevitably generated during polysilicon production. Currently, most companies treat waste gas using pipelines, buffer tanks, and scrubbing towers. Scrubbing towers are a new type of gas purification equipment. They are an improvement on floating packing layer gas purifiers and are widely used in pretreatment for industrial waste gas purification and dust removal, achieving excellent purification results.

[0003] However, upstream emissions fail to meet standards, resulting in a large amount of silicon powder entrained in the exhaust gas, causing blockages in the pipeline network, buffer tanks, and scrubbing towers. Additionally, the exhaust gas condenses upon contact with air upstream, and a large amount of condensate is carried to the buffer tanks. Here, the prolonged reaction between the condensate and deposited silicon powder causes the reactants in the buffer tanks and pipelines to harden and clog, preventing timely drainage and posing a significant hazard to on-site production. The conventional method is manual shutdown and unblocking, but this method is inefficient. Existing patented technologies disclose the following opening tooling equipment:

[0004] The patent with publication number CN218593188U and patent name "Aeration Main Pipe Opening Fixture" discloses the following: An aeration main pipe opening fixture includes a cylinder, a hole spacing positioning pin, a hole spacing positioning plate, a pipe clamp, a drill bit, a pin, a pin positioning hole, a positioning block, and a guide rail. The guide rail is installed on the workbench surface. A pipe clamp is installed above the guide rail, and a cylinder is coaxially mounted on the pipe clamp. A hole spacing positioning pin and a hole spacing positioning plate are arranged on the side. The workbench surface also has a tool table drill bit and a pin position. A positioning block is installed on the right end face of the entire fixture, and a pin positioning hole is provided at the cylinder connector next to it. The beneficial effects of this invention are: it is used for opening the main pipe of a curtain membrane aeration system and is suitable for opening aeration main pipes with different pipe diameters, different hole spacings, and different diameters.

[0005] Although the starting tool used in the above patent can reduce the workload of operators and play a role in unblocking, the starting tool does not have a sealing mechanism when it is used with pipe valves. When unblocking blocked pipelines, it is easy to cause the unblocking material to be discharged, resulting in environmental pollution and personal injury. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem that existing opening fixtures lack sealing mechanisms, directly clearing blocked pipelines and causing material discharge and personnel injury. This invention provides an opening fixture for the buffer tank of a waste gas scrubbing tower.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] A tooling for opening a buffer tank in an exhaust gas scrubbing tower includes an installation mechanism and a sealing opening mechanism to prevent material leakage. The installation mechanism is installed on a valve at a pipeline blockage point, and the sealing opening mechanism is detachably installed on the installation mechanism.

[0009] Specifically, after installing the opening fixture at the drain valve of the buffer tank (or other blocked valves in pipelines), the fixture includes a detachable mounting mechanism on the valve and a sealing opening mechanism on the mounting mechanism. Personnel use the sealing opening mechanism to open the blocked valve, clearing the sludge in the pipeline. After clearing the blockage, the valve is closed, allowing the condensate (or material in the pipeline) in the buffer tank to be safely and controllably discharged into the trench. Because the sealing opening mechanism effectively prevents material leakage, it solves the problem of direct personnel clearing the blockage, causing material discharge, and consequently causing environmental pollution and personnel injury.

[0010] Furthermore, the sealing and opening mechanism includes a drill bit assembly, a drive rod for rotating and lifting the drill bit assembly, and a sealing support assembly for preventing material discharge. The sealing support assembly is sleeved on the drive rod and fixed on the mounting mechanism. The drill bit assembly is located below the drive rod and can pass through the mounting mechanism.

[0011] Specifically, a preferred mechanism for a sealing opening mechanism is disclosed. The key feature of this mechanism is the inclusion of a sealing support component to prevent material leakage. This ensures that the drive rod drives the drill bit assembly to clear blockages in the pipeline while preventing material leakage and avoiding environmental pollution.

[0012] Furthermore, the drill bit assembly includes a auger drill bit and a connecting portion disposed on the auger drill bit, with a drive rod connected to the connecting portion.

[0013] Specifically, a preferred structure for the drill bit assembly is disclosed. Choosing this type of auger drill bit and connector facilitates subsequent installation and has the advantages of convenient operation and high work efficiency. The connector is provided with a square connecting groove.

[0014] Furthermore, the drive rod includes a bracket fixed to the top of the sealing support assembly, a fixing nut fixed to the bracket, and a threaded rod that mates with the fixing nut. The threaded rod passes through the fixing nut, the sealing support assembly, and the mounting mechanism in sequence and is connected to the drill bit assembly. A rotation drive mechanism is provided at the top of the threaded rod.

[0015] Specifically, a preferred embodiment of the drive rod structure is disclosed. This screw and nut drive structure has the advantages of simple structure and low installation and manufacturing cost. The drive rod can be driven manually or electrically. The drive rod can also be other drive mechanisms that can drive the drill bit assembly to rise and fall.

[0016] Furthermore, the rotation drive mechanism is one of a drive motor, a rotary cylinder, or a manual rotation drive mechanism, wherein the manual rotation drive mechanism is a handwheel located at the top of the threaded rod.

[0017] Specifically, the solution discloses multiple options for the rotation drive mechanism. This solution exemplifies manual drive, electric drive, and pneumatic drive, but other drive methods that can achieve the same design purpose are also possible.

[0018] Furthermore, the sealing support assembly includes a first sealing assembly, a connector, and a second sealing assembly. The first sealing assembly, the connector, and the second sealing assembly are sequentially sealed and connected from bottom to top, and all three are sleeved on the threaded rod. The first sealing assembly is fixed on the mounting mechanism, and the top of the second sealing assembly is fixed with a bracket.

[0019] Specifically, a specific mechanism of the sealing support assembly is disclosed. The structure mainly consists of three parts: upper, middle and lower, with each part sealed to the next. This structure not only solves the sealing problem but also provides support for the drive rod.

[0020] Furthermore, the first sealing assembly includes a sealing seat, a first sealing filler layer, and a first locking assembly. The sealing seat is sleeved on the threaded rod, the first sealing filler layer fills the space between the sealing seat and the threaded rod, and the first locking assembly locks the sealing seat onto the mounting mechanism.

[0021] Specifically, a preferred structure of the first sealing assembly is disclosed, which has the advantages of simple structure, reasonable design and low installation and manufacturing cost. The first locking assembly is a bolt locking assembly, and the number of bolt locking assemblies is at least 2, which are evenly distributed on the sealing seat in a circumferential manner.

[0022] Furthermore, the connector is a support sleeve, the lower part of which is fixed to the sealing seat, the upper part of the first sealing filler layer extends into the support sleeve, and the top of the support sleeve is connected to the second sealing assembly.

[0023] Specifically, a preferred structure for the connector is disclosed, in which the connector is designed as a support sleeve, serving to connect and support the upper and lower components. This structure has the advantages of reasonable design and low installation and manufacturing costs.

[0024] Furthermore, the second sealing assembly includes a second locking assembly, a packing gland, and a packing sleeve. The packing gland and the packing sleeve are arranged vertically and fitted onto the threaded rod. The second locking assembly locks the packing gland and the packing sleeve onto the top of the support sleeve, and the bracket is fixed on the packing sleeve.

[0025] Specifically, both the packing gland and the packing sleeve are circular, with the larger diameter of the packing gland being larger than that of the packing sleeve. The second locking component consists of multiple locking bolts evenly distributed around the edge of the packing gland. The locking bolts drive the packing gland to press the packing sleeve against the top of the support sleeve. The packing sleeve and the packing gland achieve a seal at the top of the support sleeve, preventing material from leaking out from the top of the support sleeve.

[0026] Furthermore, the installation mechanism is a mounting flange.

[0027] Specifically, mounting flanges are a preferred structure for installation mechanisms, facilitating the installation and removal of valves in pipelines to be unclogged.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This invention is reasonably designed. After installing the opening fixture at the drain valve of the buffer tank (or other blocked pipeline valves), the opening fixture includes a detachable mounting mechanism on the valve and a sealing opening mechanism set on the mounting mechanism. Personnel use the sealing opening mechanism to open the blocked valve, clearing the sludge in the pipeline. After clearing, the valve is closed, allowing the condensate in the buffer tank (or the material in the pipeline) to be discharged into the ground tank in a safe and controllable manner. Because the sealing opening mechanism can effectively prevent material leakage, it solves the problem of direct clearing by personnel causing material discharge, which in turn causes environmental pollution and personnel injury.

[0030] 2. The present invention discloses a preferred mechanism for a sealing opening mechanism. The key feature of this mechanism is the provision of a sealing support component to prevent material leakage. While ensuring that the drive rod drives the drill bit assembly to drill through the blocked pipeline, it prevents material leakage and avoids environmental pollution.

[0031] 3. This invention discloses a specific mechanism of a sealing support assembly. This structure mainly consists of three parts: upper, middle, and lower, with each pair of parts sealed together. This structure solves the sealing problem and also provides support for the drive rod. Attached Figure Description
