Description

Technical Field

[0001] This invention relates to the field of energetic materials technology, and more specifically to the field of energetic materials water screening and material transfer device technology. Background Technology

[0002] Energetic materials are compounds or mixtures containing explosive groups or oxidizers and combustibles that can independently undergo chemical reactions and output energy. They are an important component of military explosives, propellants, and rocket propellant formulations.

[0003] Explosives, as a common energetic material, require particle size determination during production. Currently, the common method is direct particle size measurement. However, impurities or dust adhering to the explosive surface can affect the accuracy of particle size measurement. To remove impurities, especially for water-insoluble explosives, the traditional method involves manual washing due to the special nature of the raw materials. This method cannot guarantee personnel safety or consistency in the testing process. Existing patents disclose the following filtration equipment:

[0004] The patent with publication number CN102671446A and patent name "A High-Pressure Filter Barrel" discloses the following: A high-pressure filter barrel is composed of holes, holes on a stainless steel reinforcing ring on the inner wall of the barrel, an inner layer of stainless steel perforated mesh, a flange, an outer layer of stainless steel perforated mesh, a barrel body, holes on a stainless steel reinforcing ring, holes on a stainless steel reinforcing ring at the bottom of the barrel, and a barrel bottom. Its features include a flange on the barrel body with holes, an inner stainless steel reinforcing ring on the inner wall of the barrel with holes on the inner wall of the barrel, a barrel bottom at the bottom of the barrel, a stainless steel sintered mesh in the middle layer of the barrel body, an inner layer of stainless steel perforated mesh in the inner layer of the barrel body, an outer layer of stainless steel perforated mesh in the outer layer of the barrel body, and a stainless steel sintered mesh in the middle layer of the barrel bottom. Its advantages are simple design, low cost, and high practicality.

[0005] Patent publication number CN103949105A, entitled "A Simple Filter Bucket," discloses the following: A simple filter bucket includes a lid and a bucket body. The opening at the bottom of the lid matches the upper diameter of the bucket body. The lid has a liquid inlet and a vent. The upper diameter of the bucket body is larger than the lower diameter. A clamping ring is provided around the upper part of the bucket body. A filter layer is provided inside the bucket body. A liquid outlet pipe is provided at the bottom of the bucket body. The filter layer is a plate with densely arranged pores and is movable inside the filter bucket, allowing it to be removed. There are two or more filter layers, and the pore size of the upper filter layer is larger than that of the lower layer. This invention uses a multi-layer mesh filter layer with progressively decreasing pore size, enabling continuous filtration. Each layer improves the filtration effect, achieving the effect of multiple filtrations in a single filtration, thus improving filtration efficiency.

[0006] Although the filter barrel of the aforementioned patent can clean and filter impurities on the surface of explosives, the filter device of the aforementioned patent requires manual feeding. Since explosives are flammable and explosive products, manual operation cannot guarantee the safety of personnel. In addition, the overall equipment can only play a filtering role, with low automation and affecting the filtering efficiency. Summary of the Invention

[0007] The purpose of this invention is to solve the technical problems of low automation and low filtration efficiency of existing explosive cleaning and filtration equipment before explosive particle size testing. This invention provides a material transfer device for water screening of energetic materials.

[0008] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0009] A material transfer device for water screening of energetic materials includes a mounting frame, a screen assembly, a material filtering device, and a screen flipping device. The material filtering device and the screen flipping device are mounted on the mounting frame in an up-down arrangement. The screen flipping device is used to clamp the screen assembly and feed material to the material filtering device by flipping the screen assembly.

[0010] In this solution, the main function of the water sieve device is to filter and collect the material in the sieve assembly. The sieve assembly is clamped and flipped by the sieve flipping device to transfer the material in the sieve assembly to the material filtration device, thus achieving the filtration and cleaning of the material. The whole process does not require manual operation and has the advantages of high automation, fast filtration and safety and reliability.

[0011] Furthermore, the material filtration device includes a material collection and spraying component and a filtration and collection component. The material collection and spraying component is fixed on the mounting frame and located above the filtration and collection component. The inlet of the material collection and spraying component cooperates with the screen flipping device (30), and the outlet of the material collection and spraying component cooperates with the inlet of the filtration and collection component.

[0012] In this solution, the main function of the material filtration device is to filter and collect the material in the screen assembly.

[0013] Furthermore, the filtration and collection assembly includes a filter bottle and a filter cup. The filter bottle is located at the bottom of the mounting frame, with an inlet at the top and an outlet at the bottom. A vacuum extraction port is located on the side wall of the filter bottle. The filter cup is located at the inlet of the filter bottle and directly below the outlet of the material collection and spraying assembly.

[0014] This solution discloses a preferred structure of a filtration and collection component, which mainly includes a filter bottle and a filter cup. During operation, the vacuum port of the filter bottle is connected to the vacuum system. When the device is running, the vacuum will perform filtration on the filter bottle and accelerate the leakage of water from the filter cup. This process is controlled in rhythm according to process requirements and has the advantages of low gas consumption and high filtration efficiency.

[0015] In addition, the mounting bracket is equipped with a positioning plate for the filter bottle, which is used to position the filter bottle and make it easy to align the position of the filter cup on the filter bottle with the discharge port position of the material collection and spraying assembly, so as to prevent the material collection and spraying assembly from splashing onto the outside of the filter cup when discharging.

[0016] Furthermore, the aggregate spraying assembly includes a hopper, a spraying assembly located on top of the hopper, and a control valve located at the bottom outlet of the hopper. A mounting bracket is provided with a fixing plate for mounting the hopper.

[0017] In this solution, the control valve is a pinch valve, which controls the flow of water. Pinch valves have the advantages of high reliability, small installation space, and replaceable internal rubber sleeves.

[0018] Furthermore, the feed end of the hopper is located at the top, and the size of the feed end is adapted to the size of the screen turning device. The water spraying assembly includes multiple water spray nozzles, which are evenly distributed circumferentially at the feed end of the hopper.

[0019] In this design, the hopper is a cone-shaped hopper that is wider at the top and narrower at the bottom. The cone shape is designed to facilitate the discharge of materials. The water spray assembly has multiple spray nozzles evenly distributed on the top of the hopper. This layout is intended to ensure that the materials entering the cone are washed evenly, avoiding any blank areas. The purpose of placing the spray nozzles at the top is to prevent any material from sticking to the top of the inner wall of the hopper and being unable to be washed into the filter cup.

[0020] Furthermore, the screen flipping device includes a clamp assembly, a rotary drive assembly, a lifting drive assembly, and a mounting plate. One end of the clamp assembly is fixed to the output end of the rotary drive assembly, and the other end of the clamp assembly holds the screen assembly. The rotary drive assembly is mounted on the mounting plate, and the mounting plate is slidably mounted on the mounting frame. The lifting drive assembly is fixed on the mounting frame and drives the mounting plate to rise and fall.

[0021] In this design, the clamp assembly includes a clamp and a clamp cylinder for opening and closing the clamp. The rotation drive assembly is a rotary cylinder, and the lifting drive assembly is a lifting cylinder. During operation, the clamp holds the screen assembly tightly, and then the lifting cylinder raises and lowers the screen assembly. The rotary cylinder rotates the screen assembly 180° via the clamp, pouring the material inside the screen assembly into the material filtration device below. This design has the advantages of simple structure and high efficiency in rotation.

[0022] Furthermore, the mounting frame includes a base plate and a mounting rod vertically disposed on the base plate. The mounting plate is provided with a guide slider that is slidably connected to the mounting rod, and the lifting drive assembly is fixed on the mounting rod.

[0023] In this design, the guide slider can be either a guide cylinder or a box bearing. The guide slider design makes the lifting and lowering of the mounting plate more stable. There are at least two mounting rods, with two being the preferred number. When there are two mounting rods, the number of guide sliders is also two, each fitted onto a corresponding mounting rod. The lifting drive assembly is a lifting cylinder fixed to one of the mounting rods. The cylinder body is fixed to one of the mounting rods, and the piston shaft of the cylinder is fixedly connected to the mounting plate.

[0024] Furthermore, an adjustable spray observation assembly capable of cleaning the clamp assembly is provided on the top of the mounting plate. The adjustable spray observation assembly includes a mounting platform, a telescopic drive mechanism, a support frame, an auxiliary spray assembly, and a monitoring assembly. The mounting platform is located on the top of the mounting plate, the telescopic drive mechanism is fixed on the mounting platform, the support frame is located at the telescopic end of the telescopic drive mechanism, and the auxiliary spray assembly and the monitoring assembly are both installed on the support frame.

[0025] In this design, the adjustable spray observation component allows for cleaning and observation of the screen assembly. The telescopic drive mechanism is one of a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic electric cylinder, or other linear drive mechanisms, with a telescopic cylinder being the preferred structure. The auxiliary spray component is a nozzle mounted on a support frame, and the monitoring component is a monitoring camera. The camera and nozzle are mounted on the support frame, which is in turn mounted on the telescopic cylinder, which is also fixed to the support frame. During the flipping process, the screen assembly is clamped by the clamping cylinder throughout, and the entire component is in an upward state during flipping. After flipping, the camera, nozzle, etc., descend as a whole, driven by the lifting drive component. After the screen assembly flipping device completes the above process, the system controls the nozzle to pass water or other solvents to rinse the material in the screen assembly.

[0026] Furthermore, a sealing assembly for sealing the filter cup is provided on the inlet of the filter bottle. The sealing assembly includes a sealing plug, an O-ring, a flexible annular air bladder, and an inflation port. The sealing plug is fitted onto the inlet of the filter bottle, the O-ring is positioned between the sealing plug and the inner wall of the inlet of the filter bottle, the sealing plug has an opening in the middle for receiving the filter cup, the flexible annular air bladder is positioned at the opening in the middle of the sealing plug and forms a compression seal with the outer wall of the outlet of the filter cup, and the inflation port communicates with the interior of the flexible annular air bladder.

[0027] In this design, the sealing plug of the sealing component is made of polyurethane or other soft material, which works with the O-ring to seal the filter bottle. The outer wall of the sealing plug has an annular groove for clamping. A flexible annular airbag is used to seal the bottom of the filter cup. After the filter cup is installed, the flexible annular airbag is inflated. The airbag expands and seals the bottom ring of the filter cup. After the gas is released, there is a certain gap between the flexible annular airbag and the filter cup, which facilitates the removal and placement of the filter cup.

[0028] Furthermore, it also includes a screen transfer device, which includes a frame, a clamping assembly and a three-axis drive mechanism. The clamping assembly is set in the frame for clamping and moving the screen assembly. The three-axis drive mechanism drives the clamping assembly to lift and move. The three-axis drive mechanism is mounted on the frame. The energetic material water screening material transfer device is located inside the screen transfer device.

[0029] In this solution, the frame is equipped with placement positions for screen components and filter cups. The clamping component clamps and places the screen components output from the front-end equipment, as well as the filter cups in the tray. The three-axis drive mechanism is a drive mechanism set on the frame that drives the clamping component along the X, Y, and Z axes. This drive mechanism uses a three-axis truss layout and is driven by an explosion-proof servo motor. The X direction adopts the mode of X-axis linear module + X-axis linear guide (where the frame is a square frame, there are two X-axis linear guides installed on the top of the frame in the X direction, and the X-axis linear module is arranged on one of the linear guides). The Y direction directly adopts the Y-axis linear module (the Y-axis linear module is slidably installed between the two X-axis linear guides). The Z direction adopts the Z-axis electric cylinder (the clamping component is installed at the end of the Z-axis electric cylinder).

[0030] In addition, a safety light curtain is installed on the frame at the operation point directly in front of it to provide online protection and prevent people from entering the frame, thereby protecting personal safety.

[0031] The clamping assembly integrates a screen assembly clamping device and a filter cup clamping device, primarily used for clamping and placing the screen assembly and the filter cups. The filter cup clamping device is located outside the screen assembly clamping device, so the two will not interfere with each other during operation. The screen assembly clamping device mainly consists of a clamping cylinder and a clamp; the filter cup clamping device mainly consists of a gripper cylinder and filter cup grippers. The components of the clamping assembly are manufactured using mature processing technology.

[0032] Working principle:

[0033] The clamping assembly grips and places the screen components output from the front-end device, as well as the filter cups in the tray. The three-axis drive mechanism, mounted on the frame, drives the clamping assembly along the X, Y, and Z axes. The clamping assembly integrates both screen component gripping and filter cup gripping devices, primarily used for gripping and placing the screen components and filter cups. The filter cup gripping device is located outside the screen component gripping device, ensuring no interference between the two during operation. The screen components and filter cups are then placed on the water sieve device, and the screen flipping device clamps and flips the screen components, transferring the material within the screen components into the material filtration device, ultimately achieving material filtration and cleaning.

[0034] The beneficial effects of this invention are as follows:

[0035] 1. This invention filters and collects materials in a screen assembly. The screen assembly is clamped and flipped by a screen flipping device to transfer the materials in the screen assembly to a material filtration device, thereby achieving material filtration and cleaning. The entire process requires no manual operation and has the advantages of high automation, rapid filtration, and safety and reliability.

[0036] 2. The present invention discloses a preferred structure of a filter collection component. Specifically, the filter collection component includes a filter bottle and a filter cup. During operation, the vacuum port of the filter bottle is connected to the vacuum system. When the device is running, the vacuum intervention will perform filtration on the filter bottle and accelerate the leakage of water in the filter cup. This process is controlled in rhythm according to process requirements and has the advantages of low gas consumption and high filtration efficiency.

[0037] 3. The water spray assembly of the present invention has multiple water spray nozzles evenly distributed on the top of the hopper. The purpose of this layout is to ensure that the material entering the conical hopper is washed evenly and to avoid blank areas. The purpose of setting the water spray nozzles at the top is to prevent material from sticking to the top of the inner wall of the hopper and not being washed into the filter cup.

[0038] 4. The adjustable spray observation component allows for cleaning and observation of the screen assembly. The auxiliary spray component consists of nozzles mounted on the support frame, and the monitoring component is a surveillance camera. It enables real-time observation of the screen assembly below and provides timely feedback, allowing for further control operations as needed. Attached Figure Description
