Abstract
Description
Technical Field
[0001] This utility model belongs to the field of emulsion explosive production technology, and in particular relates to a citric acid addition device for emulsion explosive production. Background Technology
[0002] Emulsion explosives are water- and oil-based explosives, typically composed of an emulsion of aqueous and oil phases. Their main components include explosives (such as ammonium nitrate), oils (such as mineral or vegetable oil), and emulsifiers. In the production of emulsion explosives, substances such as citric acid, dilute nitric acid, or phosphoric acid are often added to lower the pH value of the raw materials and ensure the reliability of subsequent processes. Currently, citric acid is mixed with water using a mixing drum. This citric acid is usually fed into the mixing drum via a hopper, but these hoppers are typically integrated and have a simple structure. The raw materials fed into the hopper fall directly into the mixing drum, which can increase the mixing load due to excessive material being added at once, requiring more time for mixing and thus affecting the equipment's production efficiency. Therefore, we propose a citric acid addition device for the production of emulsion explosives. Utility Model Content
[0003] The purpose of this invention is to provide a citric acid addition device for the production of emulsion explosives. By setting up a feeding assembly, specifically by starting motor A to drive several cams to rotate synchronously via a pin shaft, when the cam protrusion contacts the right side of the slide plate, it pushes the insert plate to slide. When the cam ends its contact with the slide plate, the insert plate will move to the right under the action of a spring. This allows for control of the opening and closing of the insert plate through the rotation of the cams, thereby achieving intermittent feeding of materials such as citric acid. This prevents excessive feeding at one time from increasing the mixing load, thus ensuring the production efficiency of the equipment. It also solves the problem that existing methods of mixing citric acid with water in a mixing drum, where the citric acid is usually transported to the inside of the mixing drum through a hopper, often a simple, integrated structure, allow the raw material to fall directly into the mixing drum. This can lead to excessive feeding at one time, increasing the mixing load and requiring more time for mixing, thus affecting the production efficiency of the equipment.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a citric acid addition device for the production of emulsion explosives, comprising an addition mechanism for injecting citric acid and water as raw materials into a citric acid solution preparation tank. The addition mechanism includes a funnel and a cylinder. An insert plate is provided at the center of the funnel. The top dimension of the funnel is larger than the bottom dimension. An insertion hole is provided on the left side of the funnel. An insert block is installed on the right side of the insert plate. The cylinder is located at the bottom of the funnel. A circular cover is provided at the top of the cylinder. A disc is installed at the bottom inside the circular cover. The interiors of the cylinder and the circular cover are interconnected. The insertion hole of the funnel and the insert block of the insert plate are compatible with each other, and the funnel and the insert plate can be inserted into each other.
[0005] Furthermore, the adding mechanism includes a feeding component for controlling the volume of raw materials entering the citric acid solution preparation tank, and the feeding component can also intermittently convey materials into the citric acid solution preparation tank. It also includes a mixing component for stirring the raw materials, mixing citric acid and water together to obtain one of the raw materials for producing emulsion explosives. The feeding component is located on the front side of the top of the mixing component, and the bottom of the feeding component is in contact with the top of the mixing component.
[0006] Furthermore, the feeding assembly includes two trapezoidal blocks, which are horizontally mirrored front and back around the insert plate. The trapezoidal blocks are installed on the inner wall of the funnel, and a notch is provided at the bottom of each trapezoidal block. A C-shaped rod is provided at the bottom of each trapezoidal block, and a locking block is installed on the front and rear sides of the top of the C-shaped rod. The notch of the trapezoidal block and the locking block of the C-shaped rod are mutually adapted and slidably connected. The top outer wall of the C-shaped rod is installed on the bottom left side of the insert plate. The guide tube at the bottom of the funnel passes through the round cover and the disc. The guide tube is connected to the cylinder, so that the material inside the funnel can flow into the equipment below through the guide tube. A guide tube is installed at the bottom of the funnel, and a rectangular box is installed at the bottom of the right outer wall of the funnel. A cavity is provided in the center of the rectangular box.
[0007] Furthermore, a box side plate is installed on the right outer wall of the rectangular box. The right side of the insert plate penetrates the right outer wall of the funnel and the left outer wall of the rectangular box. The insert plate extends into the cavity inside the rectangular box. A sliding plate is slidably connected to the center of the rectangular box. The sliding plate is rectangular in shape. The left outer wall of the sliding plate is installed on the right outer wall of the insert plate. Circular holes are opened at the four corners of the sliding plate. Sliding rods are slidably connected in the four circular holes of the sliding plate. By setting the sliding rods, the sliding of the sliding plate can be limited and corrected, so that the sliding plate can only slide along the sliding rods, avoiding the sliding plate from deflecting when it is displaced. The sliding rods are cylindrical in shape, and the left outer wall of the sliding rods is installed on the left inner wall of the rectangular box.
[0008] Furthermore, the right side of the slide rod is installed on the left outer wall of the box side panel, and the insert plate extends to the outer periphery of the rectangular box's internal area and is fitted with a spring. The left side of the insert plate with the spring fitted is installed on the left inner wall of the rectangular box, and the right side of the insert plate with the spring fitted is installed on the left outer wall of the slide plate. The rectangular box and the slide plate are flexibly connected by the spring. A pin is provided at the center of the right side of the slide plate. The pin extends outward through the rectangular box and is rotatably connected. Several cams are installed on the outer wall of the pin. The top right side of the cam has a square-round protrusion. When the cam rotates, it will drive the square-round protrusion to move, and then push the slide plate to move through the square-round protrusion. An A motor is provided on the back of the pin. The front output end of the A motor is installed on the back of the pin through a coupling.
[0009] Furthermore, the mixing assembly includes two valves, which are respectively installed at the top and bottom of the left outer wall of the cylinder. A gear box is installed on the top inner wall of the cover. Two A bevel gears are vertically arranged at the top and bottom of the center of the gear box, and B bevel gears are vertically arranged at the left and right sides of the center of the gear box. The A bevel gears and B bevel gears mesh with each other. An A shaft is installed at the bottom of the top A bevel gear. A B shaft is fitted and rotated on the outer wall of the A shaft. The disc provides protection for the gear box, A bevel gears, and B bevel gears, preventing citric acid material from accidentally splashing into the gear box and avoiding damage to the A and B bevel gears due to corrosion by citric acid. The top of the B shaft is installed at the bottom of the bottom A shaft, and the top of the A shaft passes through the cover and is rotatably connected.
[0010] Furthermore, a B motor is installed on the top of the circular cover. The bottom output end of the B motor is installed on the top of the A shaft via a coupling. Two cross plates are provided at the bottom of the B shaft. Several scrapers are installed on the side of the two cross plates that are close to each other. The scrapers are arranged in a circular array around the A shaft. The top cross plate is installed at the bottom of the B shaft. A limit ring is provided below the bottom cross plate. The bottom of the bottom cross plate is rotatably connected to the limit ring. The model of the B motor is the same as that of the A motor. Both the A motor and the B motor are YE4-80M1-2 series three-phase asynchronous motors and are both compatible with SINAMICS-V20 frequency converters. Several blades are sleeved on the outer wall of the A shaft. The blades are arranged in a vertical array around the A shaft.
[0011] This utility model has the following beneficial effects: 1. This utility model, by setting up a feeding component, specifically, starts motor A to drive several cams to rotate synchronously via a pin shaft. When the cam protrusion contacts the right side of the slide plate, it pushes the slide plate to slide. When the cam ends its contact with the slide plate, the slide plate will move to the right under the action of the spring. In this way, the opening and closing of the slide plate can be controlled by the rotation of the cam, thereby realizing the intermittent feeding of materials such as citric acid, preventing excessive feeding at one time from increasing the load on the mixing, and thus ensuring the production efficiency of the equipment.
[0012] 2. This utility model, by setting up a mixing component, specifically starts motor B, and then through the meshing between bevel gears A and B, both shafts A and B rotate. When shaft A rotates, it drives the cross plate to rotate, and then the cross plate drives the scraper to perform uniform circular motion inside the cylinder. In this way, the raw materials adhering to the inner wall of the cylinder can be scraped off through the contact between the scraper and the inner wall of the cylinder, ensuring that all raw materials are fully stirred, improving the uniformity of mixing, and thus ensuring the production quality of citric acid.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The insertion hole of the funnel 111 and the insertion block of the insert plate 112 are adapted to each other. The feeding mechanism 11 and the insert plate 112 can be interlocked. The feeding mechanism 1 includes a feeding component 11, which controls the volume of raw materials entering the citric acid solution preparation tank. The feeding component 11 can also intermittently feed materials into the citric acid solution preparation tank. The mixing component 12 is used to stir the raw materials, mixing citric acid and water together to obtain one of the raw materials for producing emulsion explosives. The feeding component 11 is located on the front side of the top of the mixing component 12, and the bottom of the feeding component 11 is in contact with the top of the mixing component 12. The feeding component 11 includes two trapezoidal blocks 1131, which are horizontally mirrored front and back with the insert plate 112 as the center. The trapezoidal blocks 1131 are installed on the inner wall of the funnel 111. A notch is provided at the bottom of the trapezoidal block 1131. A C-shaped rod 1132 is provided at the bottom of the trapezoidal block 1131. Locking blocks are installed on the front and rear sides of the top of the C-shaped rod 1132. The notch of the trapezoidal block 1131 and the locking blocks of the C-shaped rod 1132 are mutually adapted and slidably connected. The top outer wall of the C-shaped rod 1132 is installed on the bottom left side of the insert plate 112. A guide tube is installed at the bottom of the funnel 111. A rectangular box 1141 is installed at the bottom right outer wall of the funnel 111. A cavity is provided at the center of the rectangular box 1141. A box side plate 1142 is installed on the right outer wall of the rectangular box 1141. The right side of the insert plate 112 penetrates the right outer wall of the funnel 111 and the left outer wall of the rectangular box 1141. The insert plate 112 extends into the cavity inside the rectangular box 1141. A rectangular slide plate 115 is slidably connected to the center of the interior of box 1141. The left outer wall of the slide plate 115 is mounted on the right outer wall of the insert plate 112. Circular holes are provided at each of the four corners of the slide plate 115, and sliding rods 116 are slidably connected to each of these holes. The left outer wall of the sliding rod 116 is mounted on the left inner wall of the rectangular box 1141, and the right side is mounted on the left outer wall of the box side plate 1142. A spring is fitted around the outer wall of the insert plate 112 extending into the interior area of the rectangular box 1141. The left side of the spring-loaded outer wall of the insert plate 112 is mounted on the left inner wall of the rectangular box 1141, and the right side is mounted on the left outer wall of the slide plate 115.The rectangular box 1141 and the slide plate 115 are flexibly connected by a spring. A pin 117 is located at the center of the right side of the slide plate 115. The pin 117 extends outward through the rectangular box 1141 and is rotatably connected. Several cams 118 are installed on the outer wall of the pin 117. By setting up the feeding assembly 11, specifically by starting motor A 119, the motor drives the several cams 118 to rotate synchronously through the pin 117. When the protruding part of the cam 118 contacts the right side of the slide plate 115, it pushes the slide plate 112 to slide. When the cam 118 stops contacting the slide plate 115, the slide plate 112 will move to the right under the action of the spring. In this way, the opening and closing of the slide plate 112 can be controlled by the rotation of the cam 118, thereby realizing the feeding of materials such as citric acid. Intermittent feeding prevents excessive feeding at one time from increasing the mixing load and thus ensuring the production efficiency of the equipment. A motor 119 is installed on the back of the pin 117. The output end of the motor 119 is mounted on the back of the pin 117 via a coupling. The mixing assembly 12 includes two valves 123, which are respectively installed on the top and bottom of the left outer wall of the cylinder 121. A gear box 124 is installed on the inner wall of the top of the cover 1221. Two A bevel gears 1251 are vertically arranged at the top and bottom of the center of the gear box 124. B bevel gears 1252 are vertically arranged on the left and right sides of the center of the gear box 124. The A bevel gears 1251 and B bevel gears 1252 mesh with each other. The top of the A bevel gear 1251 is connected to the bottom of the gear box 1252. A rotating shaft A 1261 is installed, and a rotating shaft B 1262 is fitted and rotated on the outer wall of rotating shaft A 1261. The top of rotating shaft B 1262 is installed at the bottom of rotating shaft A 1261. The top of rotating shaft A 1261 passes through a round cover 1221 and is rotatably connected. A motor B 1263 is installed on the top of the round cover 1221. The bottom output end of motor B 1263 is installed on the top of rotating shaft A 1261 via a coupling. Two cross plates 1271 are provided at the bottom of rotating shaft B 1262. Several scrapers 1272 are installed on the side of the two cross plates 1271 that are close to each other. The scrapers 1272 are arranged in a circular array around rotating shaft A 1261. The top cross plate 1271 is installed at the bottom of rotating shaft B 1262. The bottom cross plate 1271... A limiting ring is installed at the bottom, and the bottom of the cross plate 1271 is rotatably connected to the limiting ring. By setting up the mixing component 12, specifically by starting motor B 1263, the meshing between bevel gears A 1251 and B 1252 causes both shafts A 1261 and B 1262 to rotate. When shaft A 1261 rotates, it drives the cross plate 1271 to rotate, which in turn drives the scraper 1272 to perform uniform circular motion inside the cylinder 121. This allows the scraper 1272 to scrape away the raw materials adhering to the inner wall of the cylinder 121 through contact with the inner wall, ensuring that all raw materials are thoroughly mixed, improving the uniformity of the mixture, and thus guaranteeing the production quality of citric acid.A plurality of blades 128 are fitted on the outer wall of the rotating shaft A 1261, and the blades 128 are arranged in a vertical array with the rotating shaft A 1261 as the center.
[0019] A specific application of this embodiment is as follows: During use, the valve 123 on the top left side of the cylinder 121 is opened to allow water to enter the cylinder 121. Then, the B motor 1263 is started, causing its bottom output end to drive the A shaft 1261 to rotate. This, in turn, drives several blades 128 mounted on the bottom outer wall to rotate. When the A shaft 1261 rotates, it drives the A bevel gear 1251 at the top to rotate. Then, through the meshing between the A bevel gear 1251 and the B bevel gear 1252, the A bevel gear 1251 at the bottom also rotates. When rotating, it drives shaft B 1262 to rotate. When shaft B 1262 rotates, it drives the top cross plate 1271 to rotate. Then, several scrapers 1272 installed at its bottom drive the bottom cross plate 1271 to rotate, so that the top and bottom cross plates 1271 rotate synchronously. At the same time, the bottom scraper 1272 rotates along the limiting ring installed inside the top of the cylinder 121. Then, motor A 119 is started, and its output end drives the pin 117 to rotate. At the same time, the pin 117 rotates, driving several cams 118 to rotate, so that cam 1 When the square-round protrusion of cam 118 displaces, and the square-round protrusion of cam 118 contacts the right side of slide plate 115, slide plate 115 will be squeezed by cam 118 and displaced to the left, compressing the spring and causing insert plate 112 to displace to the left. Then, insert plate 112 will slide to the left along trapezoidal block 1131 via C-shaped rod 1132 installed at the bottom left, thus sealing the internal area of funnel 111. When cam 118 and slide plate 115 stop contact, the spring will rebound, and the rebound of the spring will push slide plate 115, causing slide plate 115 to move along slide rod 11. 6. Move to the right and pull the insert plate 112 out of the funnel 111. This enables intermittent feeding of raw materials such as citric acid. The citric acid is then transported to the cylinder 121 through the conduit installed at the bottom of the funnel 111. It is then mixed with water under the left and right sides of the blade 128. The scraper 1272 scrapes off the material adhering to the inner wall of the cylinder 121, allowing it to re-participate in the mixing. After mixing is completed, motor A 119 and motor B 1263 are turned off. Then, valve 123 at the bottom left side of the cylinder 121 is opened, and the mixed citric acid solution is output. It should be noted that the control of motor A 119 and motor B 1263 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.
