Description

Technical Field

[0001] This utility model belongs to the field of mixer technology, specifically a mixer for fire clay. Background Technology

[0002] Fire cement is a commonly used binding material in industrial fields such as metallurgy, building materials and refractory material production. Its quality directly affects the sealing performance, high temperature resistance and service life of high-temperature equipment such as kilns and blast furnaces. The preparation of fire cement requires the precise proportioning of raw materials, such as refractory aggregates, binders and additives, and thorough mixing. The mixing process has extremely high requirements for material uniformity, temperature control and anti-adhesion performance.

[0003] The existing clay mixers have the following main shortcomings:

[0004] Existing fire clay mixers employ a single mixing zone or a single mixing structure, which easily leads to localized accumulation and insufficient mixing of materials during the mixing process. Fire clay raw materials contain aggregates of varying coarseness and fineness, as well as easily sedimenting binders. A single mixing mode makes it difficult to achieve three-dimensional convection and shear mixing of materials, resulting in uneven distribution of the finished fire clay composition. This affects the bonding strength and high-temperature stability of subsequent construction, and there is a problem of asynchronous power output, which can easily lead to a disconnect between the rhythm of the preceding and following processes. At the same time, fire clay materials have a certain degree of viscosity and are prone to adhering to the inner wall of the mixing chamber during the mixing process. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a mixer for fire clay, which solves the problem that the existing technology uses a single mixing zone or a single mixing structure, and the material is prone to local accumulation and insufficient mixing during the mixing process. Fire clay raw materials contain aggregates of different coarse and fine sizes and binders that are easy to settle. A single mixing mode is difficult to achieve three-dimensional convection and shear mixing of materials, resulting in uneven distribution of the composition of the finished fire clay, which affects the bonding strength and high temperature resistance stability of subsequent construction.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fire clay mixer, comprising a box body, an upper cover provided at the center of the upper end face of the box body, a feeding hopper provided at the center of the upper end face of the upper cover, a closed structure provided at the center of the lower end face of the upper cover and the center of the upper end face of the box body, and a stirring structure provided at the upper center of the inside of the box body.

[0007] The stirring structure includes a first stirring chamber, which is located at the upper center of the inside of the box. A first solenoid valve is provided at the center of the lower end face of the first stirring chamber. Slots are provided at the front and rear of the center of the upper end face of the first stirring chamber. Protective shells are slidably connected to the center of the two slots. Heaters are provided at the center of the two protective shells.

[0008] As a further embodiment of this utility model: a bearing is provided at the center of the lower inner wall of the box, a first rotating shaft is rotatably connected at the center of the inner side wall of the bearing, a guide plate is provided at the lower center of the box, the guide plate is inclined, and a serpentine stirring disc is sleeved on the upper end of the guide plate and on the outer side wall of the first rotating shaft.

[0009] As a further embodiment of this utility model: a first bevel gear is provided at the lower end of the guide plate and on the outer wall of the first rotating shaft; a stabilizing frame is provided at the lower center of one side wall of the box; a servo motor is provided at the center of the stabilizing frame on one side; a first pulley is fixedly connected to the output end of the servo motor; one end of the first pulley passes through one side wall of the box and extends into the inside of the box; and a second bevel gear is fixedly connected to the end of the pulley.

[0010] As a further embodiment of this utility model: the second bevel gear meshes with the first bevel gear, a second pulley is provided at the upper center of one side wall of the housing, a belt is sleeved between the second pulley and the first pulley, one end of the second pulley passes through one side wall of the housing and one side wall of the first mixing chamber and extends into the interior of the first mixing chamber, and a spiral stirring rod is fixedly connected to the end.

[0011] As a further embodiment of this utility model: three scrapers are arranged in a ring at the upper center of the outer side wall of the first rotating shaft, and all three scrapers are attached to the inner side wall of the box. A guide groove is provided at the center of the upper surface of the guide plate, and a second solenoid valve is provided at the lower center of the other side wall of the box.

[0012] As a further embodiment of this utility model: the closed structure includes four positioning grooves, which are respectively located at the four opposite corners of the upper end face of the box body, and positioning posts are provided at the four opposite corners of the lower end face of the upper cover, with the four positioning posts respectively adapting to the four positioning grooves.

[0013] As a further embodiment of this utility model: a magnetic groove is provided on the outer side of the center of the upper end face of the box, a sealing gasket is provided at the center of the lower end face of the upper cover, and a magnet is provided on the outer wall of the sealing gasket and on the lower end face of the upper cover, and the magnetic groove and the magnet are mutually compatible.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model adopts a dual-zone graded processing mode of pre-mixing and fine mixing, and realizes the coordinated operation of multiple mechanisms through a single power source. The spiral stirring rod in the first mixing chamber is responsible for the initial shearing and mixing of materials. With the help of an adjustable heater, the materials are pre-treated in a heated environment. Meanwhile, the serpentine stirring disc in the main mixing zone below rotates vertically to perform secondary tumbling and mixing of the falling materials, forming a three-dimensional mixing trajectory. Both are driven by the same servo motor, with belt drive driving the spiral stirring rod and gear meshing driving the serpentine stirring disc. This ensures the rhythm matching of the front and rear mixing processes and avoids the energy waste of multiple power sources. At the same time, the differentiated design of the mixing intensity and method in the two zones can adapt to the entire process requirements of fire clay from initial looseness to final dense mixing.

[0016] 2. In this invention, the special spiral surface of the serpentine mixing disc enhances the convective mixing of materials during rotation and, together with the inclined guide plate, forms a guiding thrust, accelerating the material's convergence towards the central guide trough. The three synchronously rotating annular scrapers closely adhere to the inner wall of the chamber, removing adhering materials in real time during the mixing process, preventing residual lumps from affecting the uniformity of mixing. This simultaneous realization of mixing, scraping, and guiding functions simplifies the internal structure of the equipment and improves the mixing efficiency and the integrity of material handling through the coordinated action of each component, solving the problems of easy wall clogging and excessive discharge residue in the mixer.

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution:

[0025] A clay mixer, comprising:

[0026] The box body 1 has a top cover 2 at the center of the upper end face of the box body 1, a feed hopper 4 at the center of the upper end face of the top cover 2, a closed structure 3 at the center of the lower end face of the top cover 2 and the center of the upper end face of the box body 1, and a stirring structure 5 at the upper center of the inside of the box body 1.

[0027] The stirring structure 5 includes a first stirring chamber 501, which is located at the upper center of the box body 1. A first solenoid valve 505 is located at the center of the lower end face of the first stirring chamber 501. Slots 502 are located at the front and rear of the center of the upper end face of the first stirring chamber 501. Protective shells 503 are slidably connected to the center of the two slots 502. Heaters 504 are located at the center of the two protective shells 503. A bearing 506 is located at the center of the lower inner wall of the box body 1. A first rotating shaft 507 is rotatably connected to the center of the inner side wall of the bearing 506. A guide plate 516 is located at the lower center of the box body 1. The guide plate 516 is inclined. A serpentine stirring disc 508 is fitted on the upper end of the guide plate 516 and on the outer side wall of the first rotating shaft 507. A first bevel gear 509 is located on the lower end of the guide plate 516 and on the outer side wall of the first rotating shaft 507.

[0028] The material enters the box 1 through the feed hopper 4 on the upper end of the cover 2, and first enters the first mixing chamber 501. At this time, by starting the servo motor 512, its output end drives the first pulley 511 to rotate. The first pulley 511 drives the second pulley 514 to rotate synchronously through the belt. The second pulley 514 drives the spiral stirring rod 515 at its end to rotate in the first mixing chamber 501, and performs preliminary mixing of the material entering the first mixing chamber 501. At the same time, the two heaters 504 in the first mixing chamber 501 are fixed in the slot 502 through the protective shell 503 to heat the material, improve the fluidity and mixing efficiency of the material, and ensure that the fire clay material is initially mixed evenly at a suitable temperature.

[0029] A stabilizing frame 513 is located at the lower center of one side wall of the housing 1. A servo motor 512 is located at the center of the stabilizing frame 513, near one side. A first pulley 511 is fixedly connected to the output end of the servo motor 512. One end of the first pulley 511 passes through the side wall of the housing 1 and extends into the interior of the housing 1. A second bevel gear 510 is fixedly connected to the end of the first bevel gear 510. The second bevel gear 510 meshes with the first bevel gear 510. A second pulley 514 is located at the upper center of one side wall of the housing 1. The second pulley 514 meshes with the first bevel gear 510. A belt is fitted between the pulleys 511. One end of the second pulley 514 passes through one side wall of the box body 1 and the side wall of the first mixing chamber 501, and is connected to the interior of the first mixing chamber 501. A spiral stirring rod 515 is fixedly connected to the end of the pulley. Three scrapers 519 are arranged in a ring near the upper center of the outer side wall of the first rotating shaft 507. All three scrapers 519 are attached to the inner side wall of the box body 1. A guide groove 517 is provided at the center of the upper end face of the guide plate 516. A second solenoid valve 518 is provided near the lower center of the other side wall of the box body 1.

[0030] After the initial mixing of the material in the first mixing chamber 501 is completed, the first solenoid valve 505 opens, and the material falls from the bottom of the first mixing chamber 501 into the main mixing area below the box 1. At the same time, the first pulley 511 at the output end of the servo motor 512 drives the second bevel gear 510 to rotate. Since the second bevel gear 510 and the first bevel gear 509 mesh with each other, the first bevel gear 509 drives the first rotating shaft 507 to rotate in the box 1 through the bearing 506. When the first rotating shaft 507 rotates, the serpentine mixing disc 508 on its outer wall rotates above the guide plate 516 to perform secondary mixing on the falling material and improve the mixing uniformity. At the same time, the three scrapers 519 arranged in a ring on the first rotating shaft 507 rotate with the shaft and scrape against the inner wall of the box 1 to prevent the material from sticking to the inner wall of the box 1, causing waste or affecting the mixing effect. Under the mixing action of the serpentine mixing disc 508, the material gathers along the inclined guide plate 516 towards the central guide trough 517.

[0031] After the material is fully mixed, the second solenoid valve 518 is opened, and the material is discharged from the box 1 through the guide chute 517 and the second solenoid valve 518. If further mixing is required, the second solenoid valve 518 can be closed, and the material continues to mix in the area of ​​the guide plate 516 until the desired mixing effect is achieved. During the entire mixing process, the servo motor 512 drives the spiral stirring rod 515, the serpentine stirring disc 508 and the scraper 519 simultaneously through belt drive, realizing the collaborative work of multiple structures driven by a single power source, improving energy utilization efficiency. At the same time, the heater 504 can adjust the temperature according to the characteristics of the fire clay material to ensure the mixing quality, and the sealing structure ensures the stability of the mixing environment.

[0032] The closed structure 3 includes four positioning slots 301, which are respectively located at the four opposite corners of the upper end face of the box body 1. Positioning posts 302 are located at the four opposite corners of the lower end face of the upper cover 2. The four positioning posts 302 are mutually adapted to the four positioning slots 301. A magnetic suction groove 303 is located on the outer side of the center of the upper end face of the box body 1. A sealing gasket 305 is located at the center of the lower end face of the upper cover 2. A magnet 304 is located on the outer wall of the sealing gasket 305 and on the lower end face of the upper cover 2. The magnetic suction groove 303 and the magnet 304 are mutually adapted. The four positioning posts 302 are inserted into the four positioning slots 301 on the upper end face of the box body 1 to complete the initial positioning. At the same time, the magnet 304 on the lower end face of the upper cover 2 and the magnetic suction groove 303 on the upper end face of the box body 1 attract each other, working with the sealing gasket 305 to seal the box body 1 and prevent material leakage or external impurities from entering during the mixing process.

[0033] The working principle of this utility model is as follows: Four positioning pins 302 are precisely inserted into four positioning slots 301 to form mechanical positioning, ensuring the accurate relative position of the upper cover 2 and the box 1. At the same time, the magnet 304 and the magnetic suction slot 303 attract each other to generate a tight connection force. Together with the sealing gasket 305, the box 1 is completely sealed, which can effectively prevent material splashing and leakage during the stirring process, as well as external dust and impurities from entering the box 1 and contaminating the material. The fire clay raw material is fed in through the feeding hopper 4 and guided into the box 1 by the feeding hopper 4, and falls directly into the first stirring chamber 501 located in the upper center of the box 1.

[0034] Simultaneously with material feeding, the servo motor 512 is activated, its output end rotates, and drives the first pulley 511 to rotate synchronously. The first pulley 511 drives the second pulley 514 to rotate through the belt transmission. The second pulley 514 drives the spiral stirring rod 515 to rotate in the first mixing chamber 501. The rotation of the spiral stirring rod 515 shears and mixes the fire clay raw material entering the first mixing chamber 501, achieving preliminary mixing. At the same time, according to the characteristics of the fire clay material and the mixing requirements, the heater 504 in the first mixing chamber 501 can be activated. The two heaters 504 are respectively installed inside the protective shell 503. The protective shell 503 is slidably connected in the slot 502 on the upper end face of the first mixing chamber 501. The position of the heater 504 in the first mixing chamber 501 can be adjusted according to the actual situation to ensure uniform heating. The heater 504 generates heat to heat the material in the first mixing chamber 501, improves the plasticity and fluidity of the material, promotes the preliminary fusion between materials, and lays the foundation for subsequent mixing processes.

[0035] After the initial mixing is completed, the first solenoid valve 505 receives a control signal and opens. The material that has been initially mixed and heated in the first mixing chamber 501 falls into the main mixing area at the lower center of the box 1 under the action of gravity from the opening at the center of the lower end face of the first mixing chamber 501. When the output end of the servo motor 512 drives the first pulley 511 to rotate, the second bevel gear 510 rotates together with the first pulley 511. Since the second bevel gear 510 and the first bevel gear 509 mesh with each other, the first bevel gear 509 is driven to rotate, which in turn drives the first rotating shaft 507 fixedly connected to it to rotate in the bearing 506 at the center of the lower inner wall of the box 1. When the side wall rotates and the first rotating shaft 507 rotates, the serpentine mixing plate 508 located on the outer side wall of the first rotating shaft 507 and above the guide plate 516 rotates accordingly. The special structure of the serpentine mixing plate 508 can fully stir, mix and tumble the falling material, so that the material is further evenly mixed. At the same time, the three scrapers 519 arranged in a ring at the upper center of the outer side wall of the first rotating shaft 507 rotate synchronously with the first rotating shaft 507. The scrapers 519 are in contact with the inner side wall of the box 1, which can scrape off the material adhering to the inner side wall of the box 1, avoid material accumulation and waste, ensure the cleanliness of the inside of the box 1, and at the same time ensure that all materials can participate in the stirring, thereby improving the uniformity of stirring.

[0036] Under the stirring action of the serpentine mixing disc 508, the material gradually moves towards the lower end of the inclined guide plate 516 and collects through the guide trough 517 at the center of the upper surface of the guide plate 516. When the material has been fully stirred in the main stirring area and meets the process requirements, the second solenoid valve 518 receives a control signal and opens. The material collected in the guide trough 517 is discharged from the housing 1 through the outlet of the second solenoid valve 518, completing the stirring operation. If further stirring is required, the second solenoid valve 518 can be closed. The material continues to be stirred by the serpentine mixing disc 508 in the area of ​​the guide plate 516 until the required stirring is achieved. After the mixing effect is achieved, the second solenoid valve 518 is opened to discharge the material. Throughout the entire working process, the servo motor 512 serves as the power source, driving the spiral stirring rod 515, the serpentine stirring disc 508, and the scraper 519 simultaneously through belt drive and gear meshing. This achieves coordinated operation of multiple mechanisms from a single power source, simplifies the equipment structure, and improves energy utilization efficiency. The closed structure 3 ensures the sealing of the mixing process. The heater 504 can adjust the temperature as needed to adapt to the mixing requirements of different fire clay materials. The cooperation of multiple stirring structures 5 ensures the uniformity and quality of the fire clay material mixing.

[0037] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0038] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
