Description

Technical Field

[0001] The utility model relates to the technical field of water supply for mixers, and specifically to a water discharging device for a forced double-horizontal-shaft mixer. Background Art

[0002] In the field of concrete mixing plants, the traditional water discharging of mixers is realized by pressurizing water through a pipeline pump, and some manufacturers also achieve self-flow water discharging through pressure difference. It mainly realizes four-sided water discharging by setting a square water pipeline above the main shaft of the mixer and providing vertical water nozzles or spiral water nozzles on the pipeline. When this traditional water discharging structure is in use, problems such as concrete adhesion often occur at the discharging port on the top of the mixer, the maintenance door of the mixer, and the four walls of the mixer, and serious caking occurs on the mixing shaft, affecting normal production and requiring frequent cleaning, resulting in low concrete processing efficiency. If adhesion occurs at the powder discharging port, it will also cause the powder to be unable to be discharged, prolong the operation time of the mixer, and increase the wear of the equipment.

[0003] In order to [solve the above problems], we designed a new type of water discharging device for a mixer based on the structure of a traditional double-horizontal-shaft mixer. It can achieve self-flow water discharging and at the same time flush water to the mixing shaft and the arc-shaped wall of the mixer, effectively reducing the problem of concrete adhesion at the mixing shaft, the side wall of the mixer, and the discharging port, improving production efficiency; at the same time, it does not require the use of a water pump to pressurize water, reducing production maintenance costs, etc. The design is scientific and reasonable, and has strong practicability. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water discharging device for a forced double-horizontal-shaft mixer to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water discharging device for a forced double-horizontal-shaft mixer includes a water tank. A main downcomer is connected to the bottom of the water tank, and a water distributor is connected to the lower end of the main downcomer. A plurality of inclined downward water pipes are arranged on one side of the water distributor for flushing water to the arc-shaped inner wall of the mixing body, and a plurality of vertical downcomers are arranged at the bottom of the water distributor for flushing water to the mixing shaft. The diameter of the main downcomer is larger than that of the water distributor, and the diameter of the water distributor is larger than the diameters of the inclined downward water pipes and the vertical downcomers.

[0007] As a further preferred solution of the utility model: a water valve is arranged on the main downcomer.

[0008] As a further preferred solution of the utility model: there are two corresponding water distributors, and the lower end of the main downcomer is connected to the two water distributors through a tee.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The water discharging device can make the water in the water tank rush out under high pressure in a gravity flow manner by designing three-layer water pipes with gradually decreasing diameters, without the need for a water pump to pressurize the water discharge, thus avoiding subsequent water pump maintenance problems. At the same time, by designing an inclined downward water pipe and a vertical downward water pipe, it can simultaneously flush the mixing shaft and the inner arc wall of the mixer, reducing the caking problem at the mixing shaft and the arc wall of the mixer. Moreover, the water discharging speed is fast, shortening the high-load mixing time of the mixer, and without the need for a motor and a water pump, saving energy and reducing emissions. At the same time, it also reduces the problem of material splashing and avoids the problem of caking at the powder feeding port, making it impossible to feed materials. The structure is simple, the design is scientific and reasonable, greatly improving the concrete production efficiency of the mixer. Brief Description of the Drawings

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0015] Please refer to Figure 1-2 , this embodiment provides a water discharging device for a forced double-horizontal shaft mixer, including a water tank 1. A main downpipe 2 is connected to the bottom of the water tank 1, and a water valve 7 is provided on the main downpipe 2. The water valve 7 is preferably a pneumatic valve, which is a conventional structure and will not be elaborated here. At the lower end of the main downpipe 2, a branch water pipe 4 is connected. On one side of the branch water pipe 4, a plurality of inclined downward water pipes 5 are provided for flushing the inner arc wall of the mixing body 8. At the bottom of the branch water pipe 4, a plurality of vertical downward water pipes 6 are provided for flushing the mixing shaft 9. In order to make the water in the water tank flow out by gravity with a certain pressure, the diameter of the main downpipe 2 is larger than that of the branch water pipe 4, and the diameter of the branch water pipe 4 is larger than that of the inclined downward water pipe 5 and the vertical downward water pipe 6. The specific numerical values of their diameters can be customized according to actual needs, which are conventional numerical values that can be obtained by those skilled in the art through calculation, and will not be elaborated and limited in this application.

[0016] Meanwhile, in order to make the water distribution pipe 4 applicable to the twin-shaft mixer, the number of the water distribution pipes 4 should correspond to the two mixing shafts 9 in the mixer body 8, that is, two water distribution pipes 4 are correspondingly arranged, and the lower end of the main downcomer 2 is connected to the two water distribution pipes 4 through a tee pipe 3.

[0017] In practical applications, as Figure 2 shown, the two water distribution pipes 4 are correspondingly arranged on the upper sides of the two mixing shafts 9. The distance between the vertical downcomer 6 and the mixing blades on the mixing shaft 9 is preferably 8-10 cm, which can prevent the concrete materials from splashing during water flushing due to too large a distance. After adding the concrete materials into the mixer body 8 through the powder feeding port 10 on the mixer body 8, when water needs to be discharged, open the water valve 7. The water in the water tank 1 passes through the main downcomer 2 and the water distribution pipes 4 and then is sprayed onto the arc-shaped side wall of the mixer body 8 by the inclined downcomer 5 and falls onto the mixing shaft 9 by the vertical downcomer 6, and then control the mixing shaft 9 to mix.

[0018] It should be noted that the above embodiments only specifically and clearly describe the technical solutions and technical features of the present application. For those skilled in the art, the solutions or features that belong to the prior art or common general knowledge are not described in detail in the above embodiments.

[0019] In addition, the technical solutions of the present application are not limited to the above embodiments. Those skilled in the art should take the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
