Description

Technical Field

[0001] The utility model belongs to the technical field of material distributors and relates to a four-way distributor. Background Art

[0002] A distributor is a common device used to distribute materials to different channels or positions. It is widely used in many industrial fields, such as mining, chemical industry, metallurgy, etc. It is mainly used to distribute materials to different channels or positions. A distributor usually consists of a feed port and multiple discharge ports. Materials can be distributed to different discharge positions according to specific proportions or rules as needed. The distributor is an important component in the belt conveyor system, which plays a one-to-many connection role between the upstream belt conveyor and the downstream belt conveyor.

[0003] The material distribution function of the existing distributor is usually to push the flap to the specified position through an electric push rod to achieve the effect of switching the channel between the feed port and different discharge ports, thereby realizing the change of material flow. In order to ensure the flexible rotation of the flap of the existing distributor, there is a certain gap between the flap and the shell. During the transportation of materials, it is inevitable that the materials will leak from the gap. In some production situations, different materials in the belt conveyor are prone to blockage and mixing when passing through the distributor. Especially for granular or powdery materials, it is easy to accumulate and cross-contaminate inside the distributor, resulting in inaccurate distribution or mixing, affecting product quality.

[0004] The existing four-way distributors often use multi-stage flap distributors or mobile distributors for the three fixed outlets. The flap distributor achieves the purpose of material flow switching by controlling the switching of flaps. On the one hand, the flaps cause serious and inevitable material leakage, and on the other hand, the overall structure volume becomes larger and more complex, which puts higher requirements on the space application of the equipment and increases the cost of use. The mobile distributor is a multi-valve body structure with a relatively complex equipment mechanism, which puts higher requirements on the inspection and maintenance of the equipment, and cannot achieve the requirement of distributing materials on both sides at the same time. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a four-way distributor, which eliminates the gap leakage problem caused by the flap of the traditional distributor by improving the structural form of the distributor valve body, realizes multiple discharge switches by adopting a movable discharge port, and optimizes the overall structure of the distributor to reduce the overall use cost.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a four-way distributor, including a feed chute, and three discharge chutes arranged below the feed chute, the top of the feed chute is a feed port, and a distributor valve body shell is arranged between the feed chute and the three discharge chutes; a distributor valve body is arranged in the distributor valve body shell, a slide groove is arranged on the distributor valve body shell, and a pulley is arranged at the corresponding position of the slide groove of the distributor valve body, the pulley passes through the slide groove and is slidably arranged on the platform on the distributor valve body shell; the distributor valve body is provided with a front and a rear part, and the discharge direction is changed by linear sliding back and forth.

[0007] Optionally, the three discharge chutes include a first discharge chute coaxially arranged with the feed chute, and a second discharge chute and a third discharge chute obliquely and symmetrically arranged relative to the first discharge chute, wherein two adjacent discharge chutes are connected at the top and have discharge ports at the bottom.

[0008] Optionally, the housing of the dispensing valve body is further provided with a driving mechanism, and the driving mechanism is hinged to the pulley through a connecting rod.

[0009] Optionally, the driving mode of the driving mechanism is motor reducer drive, electro-hydraulic drive, or pneumatic drive.

[0010] Optionally, the front section of the material dispensing valve body is an inverted trapezoidal funnel-shaped structure, and the bottom size thereof is the same as the top size of the first discharge chute.

[0011] Optionally, the rear section of the material dispensing valve body is a trapezoidal structure, and the bottom dimension is the same as the sum of the top dimensions of the first discharge chute, the second discharge chute, and the third discharge chute.

[0012] Optionally, the rear section structure of the material distribution valve body is further provided with a triangular-shaped blocking and distribution device at the top of the first discharge chute.

[0013] Optionally, a wear-resistant and anti-blocking structure is provided in the material contact part of the material distribution valve body, including a wear-resistant lining, a corrosion-resistant lining, an anti-sticking lining and a material accumulation structure.

[0014] Optionally, the main body of the dispensing valve body adopts a combined fixed valve body, and the outer shell of the dispensing valve body is fixed or installed on a bracket.
