[0002] As an indispensable equipment in construction projects, twin-shaft mixers play an important role in mixing cement, sand, various dry mortars and other building materials. However, the twin-shaft mixer discharge door device in the prior art has some drawbacks, which seriously affect the working efficiency of the mixer and the quality of concrete.

[0003] First, the discharge door of the traditional twin-shaft mixer is prone to deformation after long-term use, which will cause unsmooth discharge and affect the construction progress. Secondly, the existing discharge door device is inconvenient in installation and adjustment, and the gap is uneven, which not only increases the difficulty of operation, but also may cause material leakage and affect the sealing performance of the mixer.

[0004] Furthermore, poor sealing is a prominent problem in the prior art. Poor sealing can cause leakage of materials during the mixing process, which not only wastes materials but also may pollute the environment. At the same time, bearing failure is also one of the common problems of existing twin-shaft mixers. Bearing damage will directly affect the operating stability and life of the mixer.

[0005] In addition, the triangular area above the discharge door of the twin-shaft mixer is an inefficient area that the mixing device cannot reach. The material in this area is difficult to be fully mixed, and it is easy to form a dead zone, resulting in uneven mixing and affecting the quality and performance of concrete.

[0006] In order to improve mixing efficiency and uniformity of concrete, it is necessary to reduce this inefficient area as much as possible to allow the material to move fully.

[0007] In summary, the disadvantages of the existing twin-shaft mixer discharge door device mainly include door deformation, inconvenient installation and adjustment, uneven gap, loose sealing, bearing failure and mixing inefficiency area. The existence of these problems not only reduces the working efficiency of the mixer, but also affects the mixing quality of concrete and increases maintenance costs. Summary of the invention

[0031] The present invention will be further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the scope of protection of the present invention.

[0032] See also Figures 1 to 9 The present invention relates to a discharging method based on a novel twin-shaft mixer, comprising the following discharging steps:

[0033] (1) Discharging preparation stage: After the mixer completes the mixing of the materials, it is ready for discharging operation; the control system sends a signal, the telescopic rod of the oil cylinder begins to extend and retract, driving the swing arm to swing; the swing of the swing arm causes the door body to rotate around the bearing seat, gradually opening the discharging port;

[0034] (2) Discharging process: After the door body is opened to a preset angle, the material in the cylinder begins to flow out from the discharging port; the lower inclined surface of the side sealing strip cooperates with the outer cylindrical surface of the door lining, and the outer edge of the end sealing strip fits with the inner cylindrical surface of the end sealing seat to form a multi-layer sealing structure, which effectively prevents material leakage during the discharging process; the design of the bending plate helps to guide the material to flow out smoothly, reduce the accumulation of materials at the discharging door frame, and keep the discharging channel unobstructed; the opening and closing angle of the door body is precisely controlled by the cooperation of the induction plate and the sensor to ensure the accuracy of the discharging process, avoid incomplete discharging or excessive discharging, and improve the discharging efficiency;

[0035] (3) Unloading completion stage: When the material is unloaded, the control system sends a signal, and the telescopic rod of the oil cylinder retracts in the opposite direction, driving the swing arm to swing in the opposite direction; the reverse swing of the swing arm causes the door to gradually close until the unloading port is completely closed, preparing for the next mixing operation.

[0036] The above-mentioned unloading method based on the novel twin-shaft mixer has the following significant advantages:

[0037] Enhanced structural stability: Bearing seats are installed at both ends of the lower part of the cylinder to provide stable support for the door body, effectively prevent the door body from deformation, and improve the reliability of the entire unloading device. This structural design enables the door body to maintain a good working condition during long-term use, reducing problems such as unsmooth unloading caused by door body deformation, thereby ensuring the normal operation of the mixer and construction progress.

[0038] Improved operational flexibility The door is hinged with the telescopic rod of the cylinder through the swing arm, making the door more flexible to open and close, facilitating the control of the unloading process and improving the convenience of operation. The operator can accurately control the opening and closing angle of the door through the control system according to actual needs, realize precise control of the unloading amount, and improve the applicability and operational flexibility of the mixer.

[0039] Optimized sealing performance: Installing a door liner on the door body, and installing a bending plate and end seal seat on the bottom of the cylinder, together with the side sealing strips and end sealing strips, forms a closed sealing structure, which significantly improves the sealing performance and reduces material leakage. This multi-layer sealing design effectively prevents material leakage from the gap between the door body and the cylinder during mixing and unloading, avoiding material waste and environmental pollution, while also ensuring the cleanliness of the inside of the mixer, which is conducive to improving the quality of concrete.

[0040] Automatic control realization: The induction plate at one end of the door body cooperates with the sensor on the sensor mounting base to realize the automatic control of the door opening and closing angle, improving the accuracy and convenience of operation. Through the automatic control system, the parameters such as the door opening and closing angle and the unloading time can be pre-set, making the unloading process more intelligent and automated, reducing the manual operation links, reducing labor intensity, and improving production efficiency.

[0041] Easy maintenance and adjustment: By installing the adjustment seat plate and the adjustment screw at the bottom of the bearing seat, the position gap between the bearing seat and the door body can be adjusted, making maintenance and adjustment more convenient. When the equipment fails or needs maintenance, the staff can quickly adjust the bearing seat and the door body to ensure the normal operation of the equipment, reducing maintenance time and cost.

[0042] Improved mixing efficiency: The design of the new discharge device reduces the mixing inefficiency zone, allowing the material to move more fully during the mixing process, improving the mixing efficiency. The design of the bent plate helps to guide the material to flow out smoothly, reduce the accumulation of materials at the discharge door frame, keep the discharge channel unobstructed, further optimize the flow of materials, reduce the generation of dead zones, and thus improve the uniformity and performance of concrete.

[0043] Enhanced durability of the door body: The door body adopts an integral welded structure, including U-shaped plates and arc-shaped plates, as well as round flanges at both ends. This structural design enhances the durability of the door body. The integral welded structure improves the strength and rigidity of the door body, can withstand greater external forces and vibrations, is not easily deformed or damaged, extends the service life of the door body, and reduces the maintenance cost of the equipment.

[0044] Improved bearing protection: Sealing baffles are set outside the driving mandrel and the driven mandrel to effectively prevent muddy water from flowing into the bearing seat and causing bearing damage, thereby extending the service life of the bearing. The design of the sealing baffle provides a protective barrier for the bearing, avoiding bearing failure caused by muddy water erosion, improving the reliability and stability of the equipment, and reducing downtime caused by bearing failure.

[0045] Material flow optimization: The conical surface design of the end seal is conducive to the outflow of materials under the impact of extrusion during the mixing process, further optimizing the flow of materials in the inefficient area and reducing the generation of dead zones. This design allows the material to flow more smoothly during the mixing process, improves the production efficiency of the mixer and the unloading efficiency of the material, and also ensures the quality and performance of the concrete.

[0046] In summary, this unloading method based on the new twin-shaft mixer not only improves the working efficiency of the mixer and ensures the mixing quality of concrete, but also reduces maintenance costs, improves the reliability and durability of the equipment, and has significant economic and social benefits.

[0047] The unloading step is completed by an unloading device, which includes a cylinder 1, bearing seats 2 are respectively installed at both ends of the lower part of the cylinder 1, a door body 3 is installed between the two bearing seats 2, one end of the door body 3 passes through one of the bearing seats 2 and is connected to one end of a swing arm 4, the other end of the swing arm 4 is hinged with the telescopic rod of the oil cylinder 6 through the front pin 5, the cylinder body of the oil cylinder 6 is hinged on the tail seat 8 through the rear pin 7, the tail seat 8 and the sensor mounting seat 10 are fixedly installed at the lower part of the cylinder 1, and one end of the door body 3 is also fixedly installed with a sensing plate 9, and the sensing plate 9 is located on the outside of the swing arm 4. A sensor 11 that cooperates with the sensing plate 9 is installed on the sensor mounting seat 10, and the control of the opening and closing angle of the door body 3 is achieved through the cooperation between the sensing plate 9 and the sensor 11.

[0048] The above structure achieves the following advantages:

[0049] Reasonable and compact structure: By installing bearing seats at both ends of the lower part of the cylinder and installing the door body between the two bearing seats, the structural layout of the unloading device is reasonable and the space utilization rate is high. The door body can be opened and closed flexibly: one end of the door body passes through the bearing seat and is connected to the swing arm. The other end of the swing arm is hinged to the telescopic rod of the oil cylinder through the front pin shaft. The cylinder body of the oil cylinder is hinged to the tail seat through the rear pin shaft. This design makes the opening and closing of the door body more flexible and can quickly adjust the opening and closing angle of the door body according to needs.

[0050] High unloading efficiency: The opening and closing angle of the door can be precisely controlled through the cooperation of the induction plate and the sensor, thereby achieving precise control of the unloading process, avoiding incomplete unloading or excessive unloading, and improving unloading efficiency.

[0051] High degree of automation: Through the cooperation of sensors and induction plates, automatic control of the opening and closing angles of the door is achieved, reducing the number of manual operations, reducing labor intensity and improving production efficiency.

[0052] Several door linings 12 are installed on the door body 3 , and these door linings 12 help to improve the strength and wear resistance of the door body 3 .

[0053] A bending plate 13 is installed on the middle bottom discharge door frame of the cylinder 1, and several side sealing strips 14 are installed on the top surface of the bending plate 13. The lower inclined surface of each side sealing strip 14 cooperates with the outer cylindrical surface of the door lining plate 12 for sealing. An end sealing seat 15 is also installed above the bending plate 13 at the bottom of the inner end surface of the cylinder 1, and the vertical surface of the end sealing seat 15 fits with the inner end surface of the cylinder 1. The inner cylindrical surface of the end sealing seat 15 cooperates with the outer cylindrical surface of the door lining plate 12, and an end sealing strip 16 is installed on the two end surfaces of the door body 3 respectively, and the outer edge of the end sealing strip 16 fits with the inner cylindrical surface of the end sealing seat 15. The side sealing strips 14 and the end sealing strips 16 are spliced ​​in sequence to form a sealing structure.

[0054] The above scheme achieves the following advantages:

[0055] Good sealing effect: by installing several side sealing strips on the bending plate, and making the lower inclined surface of each side sealing strip cooperate with the outer circular surface of the door lining for sealing, and at the same time installing end sealing strips on both end surfaces of the door body, the outer edge of the end sealing strip fits with the inner circular surface of the end sealing seat, and the side sealing strips and the end sealing strips are spliced ​​in sequence to form a sealing structure. This multi-layer sealing design greatly improves the sealing performance of the unloading device and effectively prevents the leakage of the mixed material during the unloading process.

[0056] High sealing reliability: the vertical surface of the end seal seat fits tightly with the inner end surface of the cylinder, and the inner circular surface of the end seal seat matches with the outer circular surface of the door lining. This tight-fitting design makes the sealing structure more stable and not easily displaced due to vibration or impact, thereby ensuring the reliability of the seal.

[0057] Compact and reasonable structure: the bending plate, side sealing strip, end sealing seat and other components are installed on the middle bottom unloading door frame of the cylinder. The space layout is compact, which makes full use of the space inside the cylinder and makes the volume of the entire unloading device more compact.

[0058] Easy to install and maintain: The installation positions of various sealing strips, end seals and other components are clear, the installation process is simple, and when replacement or repair is needed, it can be quickly located and operated, reducing the difficulty and cost of maintenance.

[0059] Prevent material accumulation: The design of the bent plate helps to guide the material to flow out smoothly, reduce the accumulation of materials at the discharge door frame, and keep the discharge channel unobstructed.

[0060] Improve unloading efficiency: Good sealing performance and reasonable structural design make the unloading process smoother, reduce the unloading time and improve the production efficiency of the mixer.

[0061] The side sealing strip 14 is arranged in a wedge shape, and the end sealing strip 16 is arranged in a fan shape. Such a design is helpful to improve the sealing effect.

[0062] The end seal seat 15 is integrally formed, and includes a horizontal mounting surface 34, a vertical surface 35, a mounting hole 33, an inner circular surface 31 and a conical surface 32. The horizontal mounting surface 34 is used to fit with the bottom of the inner end surface of the cylinder 1 to fix the position of the end seal seat 15; the vertical surface 35 is perpendicularly arranged to the inner wall of the cylinder 1; the mounting hole 33 is located on the horizontal mounting surface 34, and is used for connecting the end seal seat 15 with the cylinder 1; the inner circular surface 31 cooperates with the outer circular surface of the door lining 12 to form a part of the sealing structure; the conical surface 32 is located on the side of the end seal seat 15, and is used for the material to flow out due to extrusion and impact during the mixing process.

[0063] The arrangement of the end seal seat achieves the following advantages:

[0064] One-piece molding structure: The end seal seat adopts an one-piece molding process, which makes its structure more compact and firm, reduces the structural weaknesses caused by welding or splicing processes, improves the strength and durability of the end seal seat, and makes it less likely to deform or damage during long-term use. Excellent sealing performance: The inner circular surface 31 cooperates with the outer circular surface of the door lining plate 12: This tightly matched design forms a part of the sealing structure, effectively preventing the material from leaking from the gap between the door body and the cylinder during the unloading process, and ensuring the sealing of the unloading process.

[0065] Design of the conical surface 32: The conical surface is located on the side of the end seal seat. When the material is squeezed and impacted during the mixing process, the conical surface can guide the material to flow out smoothly, reduce the accumulation and retention of the material at the end seal seat, further enhance the sealing effect, and avoid sealing failure caused by material accumulation.

[0066] Horizontal installation surface 34: fits with the bottom of the inner end surface of the cylinder 1, ensuring the horizontal positioning of the end seal seat in the cylinder, so that it can be accurately aligned with the bottom of the inner end surface of the cylinder during installation, improving the installation accuracy and stability.

[0067] The vertical surface 35 is arranged perpendicularly to the inner wall of the cylinder 1, which ensures the vertical positioning of the end seal seat in the cylinder, so that it can remain perpendicular to the inner wall of the cylinder after installation, thereby enhancing the stability of the end seal seat and avoiding poor sealing or structural failure caused by improper installation.

[0068] Mounting hole 33: located on the horizontal mounting surface 34, used for connecting the end seal seat 15 with the cylinder 1. Through the mounting hole 33, the end seal seat can be firmly fixed to the cylinder using fasteners such as bolts to ensure that it will not shift or fall off during use, thereby improving the connection reliability of the end seal seat and providing a guarantee for the stable operation of the entire unloading device.

[0069] The door body 3 is an integrally welded structure, including a U-shaped plate 18, an arc-shaped plate 19 is buckled at the opening of the U-shaped plate 18, and a circular flange 20 is connected to both ends of the U-shaped plate 18 and the arc-shaped plate 19. A driving mandrel 21 is welded in the middle of one of the circular flanges 20, and a driven mandrel 22 is welded in the middle of the other circular flange 20. A reinforcing rib plate 23 is also installed between the circular flange 20 and the driving mandrel 21, and between the circular flange 20 and the driven mandrel 22 to enhance the stability of the structure.

[0070] The setting of the door body achieves the following advantages:

[0071] Good integrity: The door body adopts an integral welded structure. The U-shaped plate and the arc-shaped plate are connected by welding to form a whole. The structure is tight and not easy to loosen, which improves the integrity and stability of the door body, making it not easy to deform or damage during use, and prolonging its service life.

[0072] Stable structure: Reinforcement ribs are installed between the circular flange and the driving spindle, as well as between the circular flange and the driven spindle. These reinforcement ribs can effectively disperse and withstand the forces acting on the door body, thereby enhancing the stability of the structure. This allows the door body to remain stable when subjected to large external forces or vibrations, thereby improving the door body's load-bearing capacity and anti-deformation ability.

[0073] Good sealing: The arc plate buckle is installed at the opening of the U-shaped plate to form a closed structure, which is beneficial to improve the sealing of the door body and prevent the leakage of media such as gas or liquid. It is suitable for occasions that require good sealing performance, such as the inlet and outlet of industrial equipment, piping systems, etc.

[0074] Easy to install: The structure of the door body is relatively simple, mainly composed of U-shaped plates, arc-shaped plates, round flanges, driving mandrels, driven mandrels and reinforcing rib plates. The components are connected by welding or bolting. The installation process is relatively convenient and quick, reducing installation costs and time.

[0075] The driving core shaft 21 and the driven core shaft 22 are provided with sealing baffles 17 on their exteriors to prevent leaked muddy water from flowing into the bearing seat 2 and causing bearing damage.

[0076] Through the above structure, the novel twin-shaft mixer unloading device of this embodiment has the characteristics of simple structure, good rigidity, convenient installation and adjustment, tight sealing, reliable support and accurate switch position. At the same time, by optimizing the structure of the door body, sealing strip and end seal seat, the possibility of dead material accumulation in the triangular inefficient area is reduced to the greatest extent.
