Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a high-efficiency double-shaft zero-gravity mixer. Background Art

[0002] In the construction industry, the weighed powder needs to be fed into the mixing machine for sufficient mixing and mixing, and then introduced into the storage bin for storage. As a common mixing and mixing equipment, the double-shaft paddle zero-gravity mixer uses the upward motion of the material in the mixer to form a fluidized layer, resulting in instantaneous weightlessness, so that it can achieve the best mixing effect. Under the action of specific overlapping blades, the material moves axially to achieve mixing in an all-round range, forming a random optimal motion state, and finally obtaining a uniform mixed material.

[0003] At present, in the actual operation process, weighing and metering equipment, double-shaft zero-gravity mixers, and storage bins are generally arranged from top to bottom in a high-low arrangement, and can be connected in the middle through a feed pipe. The mixer is usually installed on a base, with an opening in the middle of the top of the base for the mixer to unload, and a storage bin is placed below for receiving materials. However, the existing double-shaft zero-gravity mixer has a narrow outer diameter at the bottom, and is generally installed on the base through a support. There is insufficient space under the mixer barrel discharge door, resulting in the storage bin having to be moved away every time the discharge door is repaired, and maintenance is carried out from the bottom up, which is not very convenient; and the exhaust pipe of the existing mixer is long, the wiring is tortuous and takes up a lot of space, and is prone to damage and blockage.

[0025] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0026] like Figure 1-4 As shown, in this embodiment, a high-efficiency dual-shaft zero-gravity mixer is provided, which is mainly composed of a barrel 1, internal dual-shaft blades, and a driving mechanism for driving the dual-shaft blades to rotate. The driving mechanism is specifically composed of a motor 5, a reducer 50 and other components. The motor 5 and the reducer 50 are installed on one end surface of the barrel 1. The reducer 50 is connected to the internal dual-shaft blades in a transmission manner. When working, the motor 5 drives the dual-shaft blades to rotate to achieve mixing of materials.

[0027] The mixer of this embodiment is installed as a whole on a base, connected to a weighing and metering device, and a cover plate 3 is provided on the top of the cylinder 1. The internal double-axis blades can be replaced by opening the cover plate 3. A feed port 30 is also provided on the cover plate 3. The weighing and metering device above can be connected to the feed port 30 through a feed pipe, and then the weighed and metered powder can be put into the cylinder 1 for mixing. Maintenance ports are also provided on both sides of the cylinder 1, and maintenance doors 10 are provided at the maintenance ports. Opening the maintenance door 10 can facilitate the inspection and maintenance of the internal double-axis blades.

[0028] Specifically, the bottom of both sides of the cylinder 1 in this embodiment are welded with outer frame plates 2 facing downward vertically, and the two end surfaces of the cylinder 1 extend downward and are connected to the outer frame plates 2 on both sides. When the mixer is installed on the base, a certain space is formed at the bottom of the cylinder 1, and a discharge port 100 is also opened at the bottom of the cylinder 1. A discharge door 7 is arranged at the discharge port 100, and the discharge door 7 is installed at the bottom of the cylinder 1 through a rotating shaft. The cylinder 6 is installed at the lower part of the two end surfaces of the cylinder 1, and the output end of the cylinder 6 is connected to the rotating shaft through a connecting rod 60. After the mixing is completed, the discharge door 7 is opened by the cylinder 6 to allow the material in the cylinder 1 to fall from the discharge port 100 and fall into the storage bin below.

[0029] In order to facilitate the maintenance of the discharge door 7, an inspection port 20 is provided on the outer frame plates 2 on both sides, and an inspection door 21 is installed at the inspection port 20. The interval between the outer frame plates 2 on both sides is preferably not less than the radial dimension of the cylinder 1, so as to make room for the maintenance of the discharge door 7. In short, this embodiment makes room for the maintenance of the discharge door 7 by changing the design of the bottom frame shape of the cylinder 1, especially by designing the outer frame plates 2 on both sides to expand the interval, and opens the inspection port 20 and sets the inspection door 21 on the outer frame plates 2, so that the staff can directly enter from the inspection port 20 to complete the maintenance of the discharge door 7, which is convenient and quick.

[0030] In order to balance the air pressure inside and outside the cylinder 1, exhaust reflux channels 4 that follow the outer contour are welded on both outer side walls of the cylinder 1. The upper end of the exhaust reflux channel 4 is connected to the upper part of the cylinder 1, and the lower end of the exhaust reflux channel 4 passes through the outer frame plate 2 and extends to the outer wall at the bottom of the cylinder 1. In this way, the exhaust reflux channel 4 can balance the air pressure inside and outside the cylinder 1 during feeding, mixing, and unloading, ensuring that the material can enter and unload normally, and the internal circulation can also prevent the leakage of dust. At the same time, the exhaust reflux channel 4 is integrated into the outer wall of the cylinder 1 and designed according to the outer contour of the cylinder 1, which can reduce the occupied space and extend the service life of the pipeline. In addition, an inspection port is also opened in the middle of the exhaust reflux channel 4, and a closed door 40 is set at the inspection port to facilitate opening the closed door 40 for cleaning and maintenance when blockage and other problems occur.
