Description

Technical Field

[0001] The utility model relates to the field of environmental protection, in particular to a pollutant-sensitive material production mixing device. Background Art

[0002] Environmental protection generally refers to the general term for various actions taken by humans to solve real or potential environmental problems, coordinate the relationship between humans and the environment, protect the living environment of humans, and ensure the sustainable development of the economy and society. Its methods and means include engineering technology, administrative management, economics, publicity and education, etc. When testing water sources and air in the environment, it is necessary to use sensitive materials to test pollutants in water and air to determine the composition of pollutants, so as to find the source of pollution and specify solutions. When producing sensitive materials for pollutant detection, some stirring equipment is needed to stir and mix the required raw materials, such as application number: CN201521138817.1, which provides a pH sensitive material preparation device based on the gel method that is simple to operate and easy to implement, including a material crusher and a material mixing agitator, the material crusher is connected to the material mixing agitator through a discharge pipe; the material mixing agitator includes an inner barrel and an outer barrel, the inner barrel is arranged inside the outer barrel, and a winding tube is wound on the outer wall of the inner barrel between the inner barrel and the outer barrel, and the material mixing agitator also includes a stirring unit, the stirring unit includes a stirring motor, a power transmission disc connected to the power output shaft of the stirring motor, and a central stirring mechanism and an eccentric stirring mechanism are also arranged below the power transmission disc, the central stirring mechanism includes a first stirring shaft, a first stirring paddle arranged at the lower end of the first stirring shaft, and the first stirring shaft is fixed to the center of the power transmission disc; the eccentric stirring mechanism includes a second stirring shaft, a second stirring paddle arranged on the second stirring shaft, and the second stirring shaft is fixed at an eccentric position of the center of the power transmission disc.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, two stirring paddles with inconsistent depths are driven by a power transmission disc to stir and mix the raw materials, but one end of the stirring shaft for connecting the two stirring paddles is fixedly connected to the power transmission disc. This results in the two stirring paddles having a relatively fixed depth relative to the inner barrel, which may cause stratification of the raw materials during stirring, resulting in uneven mixing, thereby reducing the subsequent production efficiency of sensitive materials.

[0004] How to invent a pollutant-sensitive material production mixing device to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

However, one end of the stirring shaft for connecting the two stirring paddles is fixedly connected to the power transmission disc, which results in the two stirring paddles having a relatively fixed depth relative to the inner barrel, which may cause stratification of the raw materials during stirring, resulting in uneven mixing, thereby reducing the subsequent production efficiency of sensitive materials.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a pollutant-sensitive material production mixing device, including a stirring barrel 1, the stirring barrel 1 includes a barrel 101, and connecting pieces 102 are fixedly installed on both sides of the top opening of the barrel 101. A mounting plate 103 is arranged above the opening of the barrel 101 and is fixedly connected to the barrel 101 through the connecting piece 102. A lifting stirring assembly 2 is arranged on the mounting plate 103, and the lifting stirring assembly 2 includes a lifting disc 201, and the lifting disc 201 is connected to the mounting plate 103 through the lifting assembly. The center position of the bottom surface of the lifting disc 201 is rotatably connected to one end of a first rotating shaft 202, and the other end of the first rotating shaft 202 is fixedly connected to a main A stirring paddle 203, a plurality of second rotating shafts 204 are evenly distributed in a ring shape around the first rotating shaft 202, one end of each second rotating shaft 204 is also rotatably connected to the bottom surface of the lifting disk 201, and the other end of each second rotating shaft 204 is fixedly connected to an auxiliary stirring paddle 205, one end of the first rotating shaft 202 and all the second rotating shafts 204 extend to the inside of the cylinder 101 through the through holes correspondingly arranged on the surface of the mounting plate 103, the main stirring paddle 203 and all the auxiliary stirring paddles 205 are located inside the cylinder 101, and the plurality of second rotating shafts 204 are connected by a transmission mechanism, and the plurality of second rotating shafts 204 and the first rotating shaft 202 are connected to independent driving devices.

[0022] See also Figure 1 A discharge valve 104 is provided on the outer wall of one side of the bottom of the cylinder 101 and is connected with the interior thereof.

[0023] By providing the discharge valve 104, it is convenient to discharge the mixture after all the raw materials are mixed and stirred, so as to complete the subsequent production and processing of sensitive materials.

[0024] See also Figures 2 to 3 The lifting assembly includes a first motor 208, which is fixedly mounted on the bottom surface of the mounting plate 103. One end of the output shaft of the mounting plate 103 extends to the top of the mounting plate 103 through a through hole and is fixedly connected to the bottom end of the lifting screw 207. A threaded hole is opened through the surface of the lifting disc 201, and the lifting screw 207 is threadedly connected to the threaded hole.

[0025] Because the lifting disc 201 is threadedly connected to the lifting screw 207 through a threaded hole, and the first rotating shaft 202 and all the second rotating shafts 204 pass through the mounting plate 103 through the through hole to restrict the lifting disc 201, when the first motor 208 is started to drive the lifting screw 207 to rotate, the lifting disc 201 will independently move up and down relative to the mounting plate 103, and the displacement direction is affected by the rotation direction of the lifting screw 207. Therefore, by continuously rotating the first motor 208 forward or reversely, the lifting disc 201 can be displaced up and down, thereby driving the main stirring paddle 203 and all the auxiliary stirring paddles 205 to synchronously lift and lower inside the cylinder 101. Driven by their respective driving devices, the raw materials at different depths inside the cylinder 101 are stirred and mixed while rotating during the lifting and lowering displacement, thereby making the raw material mixing more uniform, improving the production efficiency of sensitive materials, and avoiding the situation where the raw materials are stratified and unevenly mixed due to the fixed stirring depth.

[0026] Furthermore, the top end of the lifting screw 207 is fixedly connected to a limiting plate 213 .

[0027] The limiting plate 213 can be provided to prevent the lifting disc 201 from being over-lifted and separated from the lifting screw 207 due to an operation error or equipment failure, thereby improving safety during use.

[0028] Furthermore, a second motor 209 is fixedly installed at the center of the top surface of the lifting disc 201 , and one end of the output shaft of the second motor 209 extends through a through hole to below the lifting disc 201 and is fixedly connected to one end of the first rotating shaft 202 .

[0029] The first rotating shaft 202 is driven to rotate by the second motor 209 alone. The main stirring paddle 203 is located closer to the bottom inner wall of the cylinder 101 than the auxiliary stirring paddle 205 . Therefore, the raw materials at a deeper position can be stirred and mixed under the drive of the second motor 209 .

[0030] Furthermore, the transmission mechanism includes a plurality of sprockets 211 whose number is the same as that of the second rotating shaft 204 . Each sprocket 211 is fixedly sleeved on an end of the corresponding second rotating shaft 204 close to the lifting disc 201 . All the sprockets 211 are connected by a chain 212 .

[0031] Through the cooperation of the sprocket 211 and the chain 212, all the second rotating shafts 204 are connected in transmission, so that all the auxiliary stirring paddles 205 can rotate at the same speed and in the same direction under the drive of the driving device. The auxiliary stirring paddles 205 are closer to the top of the cylinder 101 than the main stirring paddles 203 inside the cylinder 101, so that all the main stirring paddles 203 rotate synchronously to stir and mix the raw materials in the upper layer.

[0032] Furthermore, a third motor 210 is fixedly mounted on the upper surface of the lifting disc 201 , and one end of the output shaft of the third motor 210 extends through a through hole to the bottom of the lifting disc 201 and is fixedly connected to one end of one of the second rotating shafts 204 .

[0033] After starting the third motor 210, all the auxiliary stirring paddles 205 can be driven to rotate through cooperation with the transmission mechanism. Since all the auxiliary stirring paddles 205 and the main stirring paddle 203 are driven to rotate by independent driving devices, the rotation speed of all the auxiliary stirring paddles 205 can be asynchronous with the main stirring paddle 203, and even the rotation direction can be opposite to the main stirring paddle 203. When the main stirring paddle 203 and all the auxiliary stirring paddles 205 rotate at different speeds and directions, different stirring and mixing effects can be obtained. During use, it can be adjusted by adjusting the two driving devices, thereby reducing limitations in use.

[0034] Working principle: the raw materials required for the production of sensitive materials are added into the cylinder 101 through the top opening of the cylinder 101, and the second motor 209 and the third motor 210 are started to rotate the main stirring paddle 203 and all the auxiliary stirring paddles 205 to stir and mix the raw materials inside the cylinder 101. At the same time, the first motor 208 can be turned on as needed, and the lifting screw 207 is driven by the first motor 208 to rotate, so that the lifting disc 201 is independently lifted and displaced relative to the mounting plate 103, thereby driving the main stirring paddle 203 and all the auxiliary stirring paddles 205 to also perform synchronous lifting and displacement inside the cylinder 101, so that the raw materials are stirred and mixed by the reciprocating displacement up and down inside the cylinder 101. The lifting and stirring assembly 2 can achieve full stirring and mixing of raw materials at different depths, and at the same time, the stirring area is expanded, the uniformity and stirring efficiency of the raw material mixing are improved, and the efficiency of the production of sensitive materials is improved, avoiding the situation that the raw materials can only be stirred at a fixed position due to the fixed depth of the main stirring paddle 203 and the auxiliary stirring paddle 205, which may cause uneven stratification and mixing of the raw materials.

[0035] It should be noted that the specific models and specifications of the first motor 208, the second motor 209 and the third motor 210 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0036] The power supply and principles of the first motor 208 , the second motor 209 and the third motor 210 are clear to those skilled in the art and are not described in detail herein.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
