Description

Technical Field

[0001] This utility model relates to the field of mixing and dust removal technology, specifically a dust prevention structure for the continuous ton bag feed inlet of a magnesium oxide mixing tank. Background Technology

[0002] A magnesium oxide mixing tank is a device used to mix magnesium oxide with liquids. Its main purpose is to thoroughly agitate the magnesium oxide and liquid for reuse after reflux cooling at high temperatures. The mixing tank ensures uniform mixing of magnesium oxide and liquid, making it suitable for recycling after reflux cooling at high temperatures. The stirring system can continuously stir 24 hours a day, achieving rapid and uniform dispersion and mixing of the liquid. Variable frequency speed control is used to meet different process requirements.

[0003] When a large-capacity mixer is continuously feeding and mixing, the inlet of the mixing tank is open, which causes a lot of dust to be raised during the feeding process. Other feeding methods cannot meet the feeding volume requirements. Therefore, a dust prevention structure for the continuous ton bag feeding inlet of magnesium oxide mixing tank is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust-proof structure for the continuous ton bag feed inlet of a magnesium oxide mixing tank. It has the advantages of good dust reduction effect and simple operation, and solves the problem of excessive dust at the feed inlet when feeding ton bags of magnesium oxide mixing tank.

[0005] To achieve the above-mentioned objectives of good dust reduction effect and simple operation, this utility model provides the following technical solution: a dust prevention structure for the feed inlet of a continuous ton bag of magnesium oxide mixing tank, including a mixing tank body and a feed trough opened on the side of the mixing tank body, a negative pressure component is provided on the top of the mixing tank body, and a dust reduction component is provided on the outside of the feed trough.

[0006] The negative pressure assembly includes a negative pressure box fixedly installed on the top of the mixing tank body, a drive motor fixedly installed on the top wall of the negative pressure box, a negative pressure cylinder fixedly installed on the bottom wall of the negative pressure box, a rotating rod rotatably connected to the top wall of the negative pressure cylinder, a spiral blade fixedly installed on the outside of the rotating rod, several air guide pipes set on the top of the negative pressure cylinder, an annular cylinder set on the top of the air guide pipes, an air outlet pipe set on the side of the annular cylinder, an air guide block set inside the air outlet pipe, an air delivery pipe set at the bottom of the air outlet pipe, and a negative pressure pipe set on the top of the mixing tank body.

[0007] The dust suppression assembly includes several limiting frames fixedly installed on the side of the mixing tank body, a fixed seat slidably connected to the outside of the limiting frames, an annular tube inserted and fixed to the side of the fixed seat, several air outlets set on the inner side wall of the annular tube, and an air duct set on the side of the negative pressure box.

[0008] Furthermore, the top of the rotating rod passes through the negative pressure cylinder and is fixedly installed with the top and the bottom of the output shaft of the drive motor, and the upper and lower ends of the air guide pipe are connected to the annular cylinder and the negative pressure cylinder, respectively.

[0009] Furthermore, one end of the vent pipe is embedded inside the annular cylinder, and the other end of the vent pipe penetrates the side wall of the negative pressure box to the outside.

[0010] Furthermore, the air guide block is located above the connection position of the air supply pipe and the air outlet pipe. The outer side of the air guide block and the air outlet pipe are fixedly installed by threads. The side of the air guide block is provided with an inclined surface and the bottom is provided with several air outlet slots.

[0011] Furthermore, the bottom of the negative pressure pipe is provided with several insertion pipes, the bottom of which is embedded inside the mixing tank body, and a filter nozzle is provided at the bottom of the insertion pipe.

[0012] Furthermore, both the limiting frame and the fixing seat are arc-shaped structures used in conjunction with the mixing tank body. Several air outlet holes are opened on the upper and lower inner side walls of the annular tube, and the bottom of the air outlet is screwed into the interior of the air outlet hole.

[0013] Furthermore, one end of the air intake tube is embedded inside the negative pressure box and connected to the air supply tube, while the other end of the air intake tube is connected to the annular tube.

[0014] Compared with the prior art, this utility model provides a dust-proof structure for the continuous ton bag feed inlet of a magnesium oxide mixing tank, which has the following beneficial effects:

[0015] 1. The dust-proof structure of the continuous ton bag feed inlet of this magnesium oxide mixing tank is achieved by moving the fixed seat to the outside of the limit frame, so that the annular tube is aligned with the feed trough. When the drive motor is started, the output shaft of the drive motor rotates, which drives the rotating rod to rotate. The rotation of the rotating rod drives the spiral blade to rotate. The rapid rotation of the spiral blade discharges the air inside the negative pressure cylinder. The air enters the interior of the annular cylinder through the air guide pipe and then exits the negative pressure box through the air outlet pipe, which reduces the air pressure inside the negative pressure cylinder. The reduced air pressure in the negative pressure cylinder causes the insertion pipe to continuously draw in the air inside the mixing tank body and the dust generated during the injection.

[0016] 2. The dust-proof structure of the continuous ton bag feed inlet of this magnesium oxide mixing tank uses the high-speed rotation of the drive motor to drive the high-speed rotation of the spiral blades, forming a high-speed airflow. The airflow enters the air outlet pipe and passes through the inclined surface of the air guide block to enter the interior of the air delivery pipe. The gas inside the air delivery pipe passes through the air intake pipe and enters the interior of the annular pipe. The airflow is sprayed out through the air outlet, forming an air curtain on the outside of the feed trough, which intercepts the dust generated during the injection process, so that the dust can only be generated inside the mixing tank body, thereby reducing the dust generated at the feed trough and solving the problem of excessive dust at the feed inlet when feeding ton bags of magnesium oxide mixing tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 In this embodiment, a dust prevention structure for the continuous ton bag feed inlet of a magnesium oxide mixing tank includes a mixing tank body 1, a feed trough 2 opened on the side of the mixing tank body 1, a negative pressure component 3 provided on the top of the mixing tank body 1, and a dust suppression component 4 provided on the outside of the feed trough 2.

[0024] The negative pressure assembly 3 includes a negative pressure box 301 fixedly installed on the top of the mixing tank body 1, a drive motor 302 fixedly installed on the inner top wall of the negative pressure box 301, a negative pressure cylinder 303 fixedly installed on the inner bottom wall of the negative pressure box 301, a rotating rod 304 rotatably connected to the top wall of the negative pressure cylinder 303, a spiral blade 305 fixedly installed on the outside of the rotating rod 304, several air guide pipes 306 set on the top of the negative pressure cylinder 303, an annular cylinder 307 set on the top of the air guide pipes 306, an air outlet pipe 308 set on the side of the annular cylinder 307, an air guide block 309 set inside the air outlet pipe 308, an air delivery pipe 310 set at the bottom of the air outlet pipe 308, and a negative pressure pipe 311 set on the top of the mixing tank body 1.

[0025] In this embodiment, the top of the rotating rod 304 passes through the negative pressure cylinder 303 and is fixedly installed at the top and the bottom of the output shaft of the drive motor 302. The upper and lower ends of the air guide pipe 306 are connected to the annular cylinder 307 and the negative pressure cylinder 303, respectively.

[0026] One end of the vent pipe 308 is embedded inside the annular cylinder 307, and the other end of the vent pipe 308 passes through the side wall of the negative pressure box 301 to the outside.

[0027] The air guide block 309 is located above the connection position of the air supply pipe 310 and the air outlet pipe 308. The outer side of the air guide block 309 and the air outlet pipe 308 are fixedly installed by threads. The side of the air guide block 309 is provided with a slope and the bottom is provided with several air outlet slots 312.

[0028] The bottom of the negative pressure pipe 311 is provided with several insertion pipes 313. The bottom of the insertion pipes 313 is embedded inside the mixing tank body 1, and the bottom of the insertion pipes 313 is provided with filter nozzles.

[0029] It should be noted that the outer side of the spiral blade 305 is in close contact with the inner wall of the negative pressure cylinder 303, and the connection between various pipes and devices has good sealing performance.

[0030] In this embodiment, the dust suppression component 4 includes several limiting frames 401 fixedly installed on the side of the mixing tank body 1, a fixed seat 402 slidably connected to the outside of the limiting frame 401, an annular tube 403 inserted and fixed to the side of the fixed seat 402, several air outlets 404 disposed on the inner side wall of the annular tube 403, and an air duct 405 disposed on the side of the negative pressure box 301.

[0031] Both the limiting frame 401 and the fixing seat 402 are arc-shaped structures used in conjunction with the mixing tank body 1. Several air outlet holes are opened on the upper and lower inner side walls of the annular tube 403, and the bottom of the air outlet 404 is screwed into the air outlet hole.

[0032] It should be noted that the sliding connection between the limit frame 401 and the fixed seat 402 has resistance, which can maintain the relatively stable state between the fixed seat 402 and 401.

[0033] One end of the air intake tube 405 is embedded inside the negative pressure box 301 and connected to the air supply tube 310, while the other end of the air intake tube 405 is connected to the annular tube 403.

[0034] The working principle of the above embodiments is as follows:

[0035] By moving the fixed seat 402 to the outside of the limit frame 401, the annular tube 403 is aligned with the feed inlet 2. The drive motor 302 is started, and the output shaft of the drive motor 302 rotates, driving the rotating rod 304 to rotate. The rotation of the rotating rod 304 drives the spiral blade 305 to rotate. The rapid rotation of the spiral blade 305 discharges the air inside the negative pressure cylinder 303. The air enters the interior of the annular cylinder 307 through the air guide pipe 306 and then exits from the annular cylinder 307 through the air outlet pipe 308 into the negative pressure box 301, thereby reducing the internal air pressure of the negative pressure cylinder 303 and sucking in the dust generated inside the mixing tank body 1.

[0036] In addition, the high-speed rotation of the drive motor 302 drives the high-speed rotation of the spiral blade 305, forming a high-speed airflow. The airflow enters the outlet pipe 308 and passes through the inclined surface of the guide block 309 to enter the interior of the air delivery pipe 310. The gas inside the air delivery pipe 310 passes through the air intake pipe 405 and enters the interior of the annular pipe 403. The airflow is sprayed out through the outlet nozzle 404, forming an air curtain on the outside of the feed trough 2, which intercepts the dust generated during the injection, so that the dust can only be inside the mixing tank body 1, thereby reducing the dust generated at the feed trough 2, and thus solving the problem of excessive dust at the feed inlet when feeding ton bags of magnesium oxide mixing tank.

[0037] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
