Description

Technical Field

[0001] The utility model relates to the technical field of stirring and mixing equipment, in particular to stirring and mixing equipment with double feed inlets. Background Art

[0002] At present, in the field of material production, mixing and stirring equipment is usually required, such as vertical mixing and stirring equipment or vertical cylinder mixing and stirring equipment as containers for materials to undergo chemical reactions. It is widely used in industries such as petroleum, chemical, rubber, pesticides, dyes, medicines and food.

[0003] A double-feed inlet stirring and mixing device for the production of water-based metallic coatings disclosed in the Chinese utility model patent application disclosure specification 201921372805.3, although the double-feed inlet stirring and mixing device for the production of water-based metallic coatings is provided with rotating blades, which is convenient for users to enhance the uniformity of the mixing and stirring of the main body of the water-based metallic coating, and is convenient for users to use, effectively brings convenience to users, is simple to use, and easy to operate, but it is difficult to feed it evenly, and the process will cause uneven stirring and mixing, resulting in incomplete reaction between materials, affecting the quality of the product, and it is difficult to clean the machine after the stirring is completed, resulting in the accumulation of some chemical raw materials, which is easy to breed microorganisms, accelerate the corrosion of the machine, and cause damage to the machine. Failure to clean in time will also cause residues to enter the next mixing and stirring, affecting the quality of other products, and it is difficult to discharge the stirred materials, affecting the product production efficiency. Therefore, a double-feed inlet stirring and mixing device is proposed to solve this problem. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the utility model provides a dual-feed inlet stirring and mixing equipment, which solves the problems that the prior equipment cannot add, stir and discharge at the same time, has low production efficiency and is not clean enough. The present solution can add, stir and discharge at the same time, stir evenly, has high production efficiency and is clean enough.

[0006] It should be noted that: a. In the existing mixing equipment, all materials are usually added to the mixing tank, and then fully mixed. After mixing, the mixed materials are discharged (after each discharge, they need to be cleaned again, then re-added, and then mixed). It is impossible to stir while adding materials, which affects production efficiency; b. After a period of production, in order to avoid attachments on the mixing tank that affect the quality of the product, the materials on the inner wall of the mixing tank are usually cleaned after several productions. The existing practice is to directly open the lid of the mixing tank, and then use a high-pressure water pipe and a water nozzle to clean the inner wall of the mixing tank. This method may result in insufficient cleaning (because the water nozzle is at the tank mouth and has a certain distance from the inner wall of the lower part of the mixing tank, and the impact force of the cleaning water is insufficient; many chemical plants currently use this method).

[0007] The purpose of this scheme is to enable the addition, mixing and discharging of materials to be carried out simultaneously (to improve production efficiency), and to mix the added materials while they are flowing from position A to another position B, and to mix them just right when they flow to position B (the difficulty lies in how to ensure the mixing effect); and to clean the inner wall of the mixing long box during subsequent cleaning.

[0008] (II) Technical solution

[0009] To achieve the above purpose, the utility model is implemented through the following technical solutions: a double-feeding port stirring and mixing device, including a stirring long box and a feeding component, wherein a stirring component is arranged in the stirring long box;

[0010] A feeding assembly is provided on each of the two sides of the top of the long mixing box, and different materials are fed into the two feeding assemblies;

[0011] The stirring assembly includes two parallel auger shafts A, a gap is formed between the two auger shafts A, and the two auger shafts A are respectively located directly below the discharge ports of the two feeding assemblies; the two auger shafts A are arranged horizontally and parallel to each other;

[0012] When the two auger shafts A rotate, the auger shaft A on the left rotates clockwise and the auger shaft A on the right rotates counterclockwise, so that the fallen materials enter the gap between the two auger shafts A under the action of the auger shafts A to be mixed.

[0013] As the preferred technical solution of the present application, the discharge ports of the two feeding assemblies are respectively located directly above the front ends of the two auger shafts A; a discharge port is opened at the bottom of the long stirring box corresponding to the rear ends of the two auger shafts A; when the material falls on the front end of the auger shaft A, it is stirred and transported backward by the auger shaft A, and can finally be discharged from the discharge port.

[0014] As a preferred technical solution of the present application, the auger shaft includes a stirring shaft A and multiple stirring blades A, and the multiple stirring blades A are arranged at intervals on the cylindrical surface of the stirring shaft A; when the auger shaft rotates, the flow rate of the material flowing from front to back is reduced during the process of the material flowing from front to back.

[0015] As a preferred technical solution of the present application, a cleaning assembly is also provided on the top of the long mixing box; the cleaning assembly includes a water storage tank, a rotating joint, and a water spray box; a rotating joint is inserted and fixed at the bottom of the water storage tank, the lower end of the rotating joint is connected to the connecting tube, and a water spray box is provided at the lower end of the connecting tube, and a plurality of nozzles are provided on the water spray box; the water storage tank is fixed on the upper surface of the long mixing box, and the rotating joint, the connecting tube, and the water spray box are located in the long mixing box; a water pump is installed in the water storage tank, and the water inlet pipe of the water pump is placed on the bottom surface of the water storage tank, and the water outlet pipe of the water pump is connected to the inlet of the rotating joint; a driven wheel is provided on the outer sleeve of the connecting tube, and the driven wheel is connected to the driving wheel on the driving mechanism via a belt;

[0016] When the driving mechanism is working, it will drive the central axis tube, connecting tube and water spray box of the rotary joint to rotate. At the same time, the water pressurized by the water pump passes through the outer cylinder shell of the rotary joint, the central axis tube, connecting tube, water spray box, and finally sprayed out from the nozzle.

[0017] As a preferred technical solution of the present application, the long stirring box is provided with a plurality of cleaning components at different positions, and each cleaning component is connected to the driving mechanism via a corresponding belt; the driving mechanism includes a motor C, which is fixed on the upper surface of the long stirring box, and the output shaft of the motor C extends into the long stirring box, and a driving wheel is sleeved on the output shaft; when the driving mechanism is working, different positions in the long stirring box are cleaned through the plurality of cleaning components.

[0018] As a preferred technical solution of the present application, a plurality of nozzles are arranged on the circumferential side of the water spray box, and the angle between the nozzles and the horizontal plane is 45°; an extension tube is arranged at the bottom of the water spray box, and the length of the extension tube exceeds the radius of the water spray box, and a nozzle is installed at the end of the extension tube, and the nozzle at the end of the extension tube is aligned with the inner side wall and the inner top wall of the mixing box.

[0019] As a preferred technical solution of the present application, the feed assembly includes a material box and a guide tube; the material box has a conical bin that is larger at the top and smaller at the bottom, the guide tube is horizontally arranged and one end is connected to the bottom of the conical bin, and a discharge pipe is provided at the lower side of the other end;

[0020] A rotatable auger shaft B is arranged in the guide pipe, and a switch valve is arranged at the bottom of the conical bin; after the conical bin is discharged, the auger shaft guides the material through the guide pipe to the top of the auger shaft A; and the amount of added material is controlled by controlling the rotation speed of the auger shaft.

[0021] For ease of understanding, the principles and core design points of this solution are explained:

[0022] 1. Work process;

[0023] a. By adding corresponding materials into the conical bins of different feeding components, the auger shaft feeds the materials into the discharge pipe, and the materials dropped from the discharge pipe just fall at the front end of the auger shaft A. The upper parts of the two auger shafts A gradually approach and rotate so that the materials are squeezed into the gap between the two auger shafts A (which is conducive to the mixing of materials); b. The materials are stirred and stirred under the action of the stirring blades A of the auger shaft A, and the materials flow from the front end to the rear end of the auger shaft under the action of the stirring blades A (there are spacings between the stirring blades A, so that the materials are not always acted upon by the stirring blades A, which can slow down the flow of the materials and is conducive to full stirring. As long as the length of the stirring box is long enough, good stirring can be achieved). When the materials flow to the rear end, uniform stirring has been completed, and then the stirred materials are discharged through the discharge port;

[0024] Second, the feeding assembly is provided with a horizontal guide tube and a corresponding auger shaft B;

[0025] If the feeding component adds liquid material (the material in this solution), a certain pressure is generated through the auger shaft B, and it can be injected into the mixing tank below the liquid surface, so that it can be better acted on by the auger A (if there is no auger shaft B to add pressure, and it only relies on gravity, the depth of the liquid material injected into the liquid surface is relatively deep);

[0026] Of course, this structure also has certain advantages for feeding powder materials. If it is a powder material (not the material of this solution, but an expansion solution, which is also within the scope of protection of this application), since the guide pipe is arranged horizontally, when the auger shaft B does not rotate, the feeding will stop (here it refers to the powder material. If it is stirred in the mixing long box, additional water can be added through the cleaning component), which is conducive to controlling the amount of feeding (most of the existing methods control the feeding by opening and closing the door. There is a process for opening and closing the door. When the door is closed, any material leaks out; and the advantage of the horizontally arranged guide pipe is that when the auger shaft B stops, the feeding can be stopped immediately);

[0027] 3. After the materials are added, they are transported and stirred during the process of flowing from the front end to the rear end of the auger shaft. When they flow to the rear end, they are stirred evenly. In addition, when different materials are initially added, they are allowed to flow to the gap between the two auger shafts to complete the initial good mixing. Then, the length of the stirring long box and the spacing of the stirring blades A on the stirring shaft A are set to increase the time the materials stay in the stirring long box to improve the stirring effect.

[0028] Fourth, by extending the cleaning component into the long mixing box, the distance between the nozzle and the inner wall of the long mixing box is reduced, and each cleaning component is equipped with a water pump for pressurization, and the cleaning effect is increased by nozzles in different directions (the traditional cleaning method is to flush directly with a high-pressure water pipe, but this solution is a long mixing box and cannot be flushed with a high-pressure water pipe).

[0029] In summary, the technical effects and advantages of the utility model are:

[0030] 1. It can simultaneously carry out feeding, stirring and discharging. When the material is added to the front end of the auger shaft A, it is transported to the rear end under the action of the auger shaft A, and the stirring and discharging are completed at the rear end of the auger shaft B;

[0031] In addition, by increasing the length of the long stirring box and setting the spacing of the stirring blades A on the stirring shaft A, the time the material stays in the long stirring box is increased to ensure that it can be fully and evenly stirred;

[0032] 2. In the cleaning components, the distance between the corresponding nozzle and the long mixing tank is small (each component has a water pump and a nozzle facing the inner wall of the mixing tank at different positions), and the cleaning effect is good (the traditional method is to use a high-pressure water gun to flush directly, and the flushing effect is not ideal).

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] (Example 1)

[0046] The long stirring box 2 is placed on the bottom plate 1, and its length direction is the front-to-back direction; a feeding assembly 6 is respectively installed on the left and right sides of the front end of the stirring box 2 through corresponding brackets (including multiple vertical support columns 3 and horizontal fixing rods 8, and the fixing rods 8 fix the multiple support columns 3 to form a bracket);

[0047] Among them, in the mixing long box 2, two auger shafts A are arranged along the front-to-back direction, the two auger shafts A are parallel to each other, one is located on the left side and the other is located on the right side, and there is a distance between the two auger shafts A. When viewed from the front to the back, the auger shaft A on the left side rotates clockwise, and the auger shaft A on the right side rotates counterclockwise;

[0048] The auger shaft A includes a stirring shaft A503 and a plurality of stirring blades A504. The plurality of stirring blades A504 are arranged on the cylindrical surface of the stirring shaft A503, and there is a spacing between adjacent stirring blades A504. The stirring blades A504 are spiral blades in the shape of an auger. In addition, the two ends of the stirring shaft A503 are passed through the front and rear walls of the stirring long box 2 through bearings (bearing seals are provided at the bearings, which are the sealing design of general bearings, which is the prior art and will not be repeated here). The front and rear ends of the stirring shaft A503 (the ends passing through the front and rear walls of the stirring long box 2) are arranged on the bottom plate 1 through a support seat 501, and the front end of the stirring shaft A503 is connected to the motor A502 drive.

[0049] The outlets of the two feeding assemblies 6 are respectively located directly above the front ends of the two auger shafts A; at the rear end of the auger shaft A, a discharge port 9 is opened on the bottom surface of the long mixing box 2;

[0050] During operation: a. Two different liquid materials are fed in through two feeding components 6, and liquid materials with a certain pressure are formed under the action of the stirring shaft B; b. The pressurized liquid material is injected into the stirring box 2 below the liquid surface, and can be acted on by the auger shaft A in time. Since the auger shaft A on the left rotates clockwise and the auger shaft on the right rotates counterclockwise, the injected material is guided to the gap between the two auger shafts A, so that the two different materials can be well mixed in the initial stage; c. Under the action of the stirring blades A, the material flows from the front end to the rear end of the auger shaft A, and is stirred simultaneously during the flow. Since there is a gap between the stirring blades A and as long as the length of the stirring box 2 is long enough, when the material flows to the rear end of the stirring shaft, uniform stirring has been completed, and then it is discharged through the discharge port 9.

[0051] See also Figure 1 , Figure 2 and Figure 3 , the feeding assembly 6 is designed, specifically including a material box 601 and a guide pipe 603; wherein the material box 601 has a conical bin 602 which is larger at the top and smaller at the bottom, a switch valve is provided at the bottom of the conical bin 602, and the bottom of the conical bin 602 is also connected to the guide pipe 603, and a discharge pipe 604 is provided at the lower side of the end of the guide pipe 603 (away from the end of the conical bin 602);

[0052] Furthermore, the guide tube 603 is arranged horizontally, and an auger shaft B is arranged therein;

[0053] During operation, liquid material is added through the conical bin 602 , and through the action of the auger shaft B, the liquid material has a certain pressure and is thus sprayed into the mixing long box 2 below the liquid surface.

[0054] In this embodiment, refer to Figure 3 The auger shaft B includes a stirring shaft B606 and an auger blade B607. The auger blade B607 is located on the cylindrical surface of the stirring shaft B606.

The vertical section is connected to the conical bin 602. The auger shaft B606 is arranged as a horizontal section. The stirring shaft B606 passes through the rear end of the horizontal section and is connected to the motor B605, and a corresponding bearing is provided at the passing point. A bearing seal is provided at the bearing. The bearing seal is a prior art and will not be described here).

[0055] In this embodiment, the material box 601 covers the conical bin 602 through the cover 7 .

[0056] (Example 2)

[0057] On the basis of embodiment 1, a cleaning component 4 is further provided on the long stirring box 2 to achieve good cleaning of the inner wall of the long stirring box 2;

[0058] See also Figure 4 , specifically comprising a water storage tank 401, a rotary joint, and a water spray box 404; wherein the water storage tank 401 is fixed on the upper surface of the long mixing box 2, a rotary joint is installed on the bottom surface of the water storage tank 401, the lower end of the rotary joint is fixed and connected to a connecting tube 403, the lower end of the connecting tube 403 is fixed and connected to a water spray box 404, and a plurality of nozzles 405 are arranged on the water spray box 404;

[0059] A plurality of nozzles 405 are arranged around the water spray box 404, and the angle between the nozzles 405 and the horizontal plane is 45°; in addition, an extension pipe 409 is arranged at the bottom of the water spray box 404, and the length of the extension pipe 409 exceeds the radius of the water spray box 404. The nozzle 405 is installed at the end of the extension pipe 409, and the nozzle 405 at the end of the extension pipe 409 is aimed at the inner side wall and the inner top wall of the long mixing box 2;

[0060] A water pump is installed in the water tank 401, the water inlet pipe of the water pump is placed on the bottom surface of the water tank 401, and the water outlet pipe of the water pump is connected to the inlet of the rotary joint;

[0061] Furthermore, the outer sleeve of the connecting tube 403 is provided with a driven wheel 410, and the driven wheel 401 is drivingly connected to the driving mechanism;

[0062] During operation: a. The water in the water tank 401 is extracted and pressurized by a water pump, and then sent to the inlet of the rotary joint. Finally, the water flows out from the outlet of the rotary joint and flows through the central axis tube, the connecting tube 403, and the water spray box 404. Finally, the water in the water spray box 404 is sprayed out from the nozzles 405 in different directions to clean the inner walls of different positions of the mixing long box 2; b. The connecting tube 403 and the water spray box 404 are driven to rotate by a driving mechanism, so that each nozzle 405 can rotate circumferentially with the rotary joint as the axis, so that the nozzle 405 does not spray water at a fixed position, which can improve the cleaning effect.

[0063] In this embodiment, a plurality of cleaning components are arranged on the upper surface of the long stirring box 2 at intervals along the length direction, so as to fully clean the inner wall of the entire long stirring box 2 (at least two cleaning components 2 are arranged).

[0064] In this embodiment, the driving mechanism includes a motor C406, which is fixed on the upper surface of the long stirring box 2. The output shaft of the motor C406 extends into the long stirring box 2, and a driving wheel 407 is sleeved on the output shaft; the driving wheel 407 is connected to the driven wheel 410 on the connecting tube 403 through a belt 408.

[0065] In this embodiment, adjacent cleaning components 4 can be driven by the same driving mechanism.

[0066] The practical working principle of the present invention is as follows: the feeding component 6 and the cleaning component 4 are composed of the first step of adding the liquid material to be mixed and stirred into the feeding component 6. The feeding component 6 drives the stirring shaft B606 to rotate through the motor B605, thereby driving the auger blade B607 to rotate, thereby feeding the material into the stirring long box 2, and allowing the liquid material to be injected into the stirring long box 2 below the liquid surface; the feeding component 6 is then sealed through the cover 7 to prevent impurities and dust in the air from entering the stirring long box 2 and affecting the quality of the product. The material is then stirred through the stirring component 5. The stirring component 5 drives two different stirring shafts A503 to rotate through two motors A502, thereby causing the stirring blades A504 on the outside of the two stirring shafts A503 to rotate alternately (one clockwise and the other counterclockwise), so that the material at the front end of the auger shaft A is guided to the distance between the two auger shafts A, and the stirring blades A50 4, it can not only stir but also allow the material to flow from the front end to the rear end. The stirred material is finally discharged from the discharge port 9 at the rear end of the auger shaft A, which can allow feeding-stirring-discharging to be carried out simultaneously, thereby improving production efficiency; then the stirring long box 2 is cleaned by the cleaning component 4, and the cleaning component 4 sucks the water from the water storage tank 401 into the water spray box 404 through a water pump, and then sprays it out through the nozzle 405. The nozzle 405 and the water spray box 404 are at a 45° angle to better clean the stirring long box 2. The extension pipe 409 and the nozzle 405 at the bottom of the water spray box 404 can clean the inner side wall and the inner top wall of the stirring long box 2. The motor C406 drives the driving wheel 407 to rotate, so that the belt 408 drives the driven wheel 410 to rotate, thereby driving the water spray box 404 to rotate, so that the cleaning component 4 can better clean the stirring long box 2 to prevent the growth of bacteria inside it.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
