Description

Technical Field

[0001] The present application relates to the technical field of vertical-shaft planetary mixers, and in particular to a vertical-shaft planetary mixer with a discharge door protection structure. Background Art

[0002] A vertical planetary mixer is a device used to mix various aggregates. It mainly includes a casing, at least one rotating mixing shaft, and a drive device. In order to facilitate the inspection of the interior of the casing, an inspection door is often opened on the casing. At the end of production, the inspection door also serves as a discharge door to effectively discharge the material inside the mixer.

[0003] According to a vertical-shaft planetary mixer disclosed in Chinese patent publication No. CN207888916U, the vertical-shaft planetary mixer includes a cylindrical casing, at least one rotating shaft, a stirring system, a driving device, and an inspection door arranged on the casing. The inspection door is arranged on the side wall of the casing, and a visual window made of a transparent material is embedded in the inspection door. A cleaning mechanism for cleaning the visual window is provided on the side wall of the inspection door facing the interior of the casing. By arranging the inspection door on the side of the casing, the inspection and maintenance work of the staff can be facilitated, and at the same time, it is beneficial for the staff to observe the material stirring situation inside the casing at multiple levels and grasp the stirring situation in time; by arranging the cleaning mechanism, the cleaning of the visual window can be effectively ensured, and the mortar is prevented from solidifying on the visual window and affecting the use of the visual window.

[0004] However, this patent still has certain shortcomings in actual use. Since this patent uses a nozzle to spray water to clean the inside of the visual window, and when the mixing work is in progress, the inside of the mixer will be filled with a large amount of material, that is, the inside of the visual window will continue to contact the material. The water spraying method can only make the current field of view clear, and it is easy to become blurred again after the water spraying is stopped. In addition, adding unnecessary water when the mixer is stirring the material is likely to affect the mixing effect of the material. In this regard, based on the fit with the actual situation, this application provides a vertical shaft planetary mixer with a discharge door protection structure to solve the above problems.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] See also Figures 1 to 3The present application provides a technical solution: a vertical-shaft planetary mixer with a discharge door protection structure, comprising a top cover 201 fixed to the top of the mixer housing 1, a plurality of top windows 202 being passed through and fixedly installed on the outer side of the top cover 201, and a stirring mechanism 300 being installed between the outer side and the inner side of the mixer housing 1; through the coordinated use of the mixer housing 1, the top cover 201, the top window 202 and the stirring mechanism 300, the field of view inside the discharge door can be effectively protected while the actual mixing efficiency can be improved to a certain extent, so that the field of view of the discharge door can become relatively clear, and at the same time, no additional material will be added to the mixing material, thereby not affecting the mixing effect and refrigeration, so that the overall work quality can be guaranteed.

[0031] In this embodiment, the stirring mechanism 300 is a structure for effectively stirring the material and protecting the inner field of view of the discharge door.

[0032] like Figure 1 、 Figure 2 and Figure 3 As shown, the stirring mechanism 300 includes a driving mechanism 301 fixedly mounted on the top of the top cover 201, an active rod 302 rotatably connected between the inner top wall of the top cover 201 and the inner bottom wall of the mixer housing 1 through a bearing, eight fixed rods 303 fixed to the outside of the active rod 302, a connecting plate 304 fixed between the ends of the two corresponding fixed rods 303 away from the active rod 302, a scraper 305 fixed to the side of the connecting plate 304 away from the active rod 302, a plurality of first special-shaped stirring members 306 fixed to the outside of the bottom fixed rod 303, and a plurality of first special-shaped stirring members 306 fixed to the outside of the bottom fixed rod 303. Several second special-shaped stirring members 307 are fixed on the top of the fixed rod 303, several connecting holes 308 are opened on the outside of the mixer shell 1, several discharge door frames 309 are hinged to the outside of the mixer shell 1 and can be inserted into the inner side of the corresponding connecting holes 308, several reinforcement frames 310 are fixed to the inner side of the discharge door frame 309, a transparent plate 311 is fixedly installed on the inner side of the reinforcement frame 310, a steel structure support net 312 is fixed to the inner side of the discharge door frame 309, and a door bolt 313 is fixedly installed between the outer side of the discharge door frame 309 and the outer side of the mixer shell 1.

[0033] It should be noted that the top cover 201 is in a truncated cone shape, and the top window 202 is located on the outer inclined surface of the top cover 201, so that the top window 202 can facilitate the user's auxiliary viewing to meet the observation needs of different perspectives. The driving mechanism 301 is composed of a servo motor and a reducer. The output shaft of the servo motor is fixedly connected to the input shaft of the reducer. The output shaft of the reducer passes through the top of the top cover 201 and is fixedly connected to the top of the active rod 302, so that the driving mechanism 301 can stably drive the active rod 302 to rotate.

[0034] In addition, every two fixed rods 303 form a group, and the outer side of the scraper 305 can be fitted with the inner side of the mixer shell 1, so that the connecting plate 304 can be divided into four different positions, which is convenient for scraping and cleaning the inner side of the mixer shell 1. Two first special-shaped stirring pieces 306 are fixed on the outer side of each bottom fixed rod 303, and the first special-shaped stirring piece 306 is fixedly connected to the bottom of the top fixed rod 303 of the same group. The first special-shaped stirring piece 306 and the second special-shaped stirring piece 307 are both V-shaped, and the positions of each group of first special-shaped stirring pieces 306 and second special-shaped stirring pieces 307 are different, so that the active rod 302 can drive the first special-shaped stirring piece 306 and the second special-shaped stirring piece 307 to perform circular motion through the fixed rod 303, and through the setting of different positions, the circular motion trajectories of each group of first special-shaped stirring pieces 306 and second special-shaped stirring pieces 307 are different, thereby meeting the comprehensive stirring needs inside the mixer shell 1.

[0035] At the same time, three reinforcement frames 310 are fixed on the inner side of each unloading door frame 309. The reinforcement frames 310 are aluminum alloy frames. The positions of the corresponding three reinforcement frames 310 are distributed as follows: two are located on the inner side of the unloading door frame 309 close to the active rod 302, and the other is located on the inner side of the unloading door frame 309 away from the active rod 302. The opposite sides of the two reinforcement frames 310 close to the active rod 302 are fixedly connected to the outer side of the corresponding steel structure support net 312. The thickness of the transparent plate 311 is the same as that of the other two reinforcement frames 310. Due to the thickness of the strengthening frame 310, the outer side of the steel structure support net 312 is fixedly connected to the opposite side of the two corresponding transparent plates 311, so that the steel structure support net 312 can play an auxiliary supporting role for the two transparent plates 311 on the side close to the active rod 302, and then cooperate with the edge reinforcement of the strengthening frame 310 to make the transparent plates 311 as a whole have higher strength, making them not easy to break. Among them, the transparent plates 311 can be high-transparency acrylic plates or high-hardness tempered glass, so that they can meet the requirements of observation and sealing.

[0036] In addition, the shapes of the reinforcement frame 310 and the transparent plate 311 on the side closest to the active rod 302 match the inner side of the mixer housing 1, so that the scraper 305 can scrape the transparent plate 311 synchronously during the scraping process to meet the cleaning needs of the transparent plate 311. The outer side of the discharge door frame 309 is bonded with a sealing ring that abuts against the inner side of the connecting hole 308. The sealing ring can increase the sealing performance of the connection between the discharge door frame 309 and the connecting hole 308, and then position it through the door bolt 313 to prevent internal materials from leaking.

[0037] It should also be noted that a discharge pipe 401 is fixed to the bottom of the mixer housing 1, and a discharge valve 402 is fixedly installed on the outside of the discharge pipe 401. The inner bottom wall of the mixer housing 1 is slightly inclined toward one side of the discharge pipe 401, and the interior of the mixer housing 1 is connected to the interior of the discharge pipe 401, so that the material inside the mixer housing 1 can be easily discharged.

[0038] The working principle of the above embodiment is:

[0039] When stirring and mixing materials, various types of aggregates are put into the interior of the mixer housing 1, and the driving mechanism 301 is started to drive the active rod 302 to rotate, so that the fixed rod 303 drives the connecting plate 304 and the scraper 305 to continuously scrape and clean the inner wall of the mixer housing 1 and the corresponding transparent plate 311 close to the active rod 302, so as to ensure the field of view of the transparent plate 311 in the unloading door frame 309, which plays an effective protective role. At the same time, the first special-shaped stirring member 306 cooperates with the second special-shaped stirring member 307 to effectively stir the interior of the mixer housing 1, so that the internal materials can be mixed quickly. After the stirring is completed, the discharge valve 402 is opened to discharge the material inside the mixer housing 1 through the discharge pipe 401.

[0040] Compared with the prior art, the vertical-shaft planetary mixer with a discharge door protection structure can effectively protect the field of view inside the discharge door while improving the actual mixing efficiency to a certain extent through the coordinated use of the mixer housing 1, the top cover 201, the top window 202 and the stirring mechanism 300, so that the field of view of the discharge door can become relatively clear, and at the same time, no additional material will be added to the stirred material, thereby not affecting the stirring effect and refrigeration, so that the overall work quality can be guaranteed, solving the shortcoming of the existing vertical-shaft planetary mixer that it is easy to affect the actual quality of the stirred material during actual use.

[0041] The electrical components appearing in this article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in this field. The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field. These are all existing publicly available power connection technologies and will not be described in detail in this article.
