According to the utility model, the overhaul mechanism is arranged, when the overhaul is stopped, the cleaning discharge hole is opened to discharge dust, so that the dust materials in the overflow screw machine can be discharged, the dust materials are prevented from being accumulated in the screw shaft and hardened due to moisture regain, and dust and sand are not easy to fly upwards during cleaning, so that the environment is not polluted.

Description

Cleaning device of overflow screw machine

Technical Field

The utility model relates to the technical field of spiral conveying equipment, in particular to a cleaning device of an overflow spiral machine.

Background

The overflow screw machine discharging mode is overflow discharging, and the following problems are found in the using process:

1. when the system is shut down and overhauled, the overflow screw machine cannot discharge all the dust in the system, and the dust in the system cannot be started to run again due to hardening caused by moisture regain, so that the dust in the overflow screw machine can be cleaned before the system is started after each maintenance;

2. when the dust collector is in normal production, when the caking dust enters the overflow screw machine, the blocking is easy to form to cause overload of the motor, and tripping is carried out, personnel are required to clean the blocking after tripping, the cleaning work difficulty is high, the dust flies upwards, the working strength of the personnel is increased, and the dust collection work of normal production is also influenced;

3. the dust material temperature of clearance is high during production, has certain potential safety hazard to overflow screw machine's clearance work.

Disclosure of Invention

Based on the above, the utility model aims to provide a cleaning device of an overflow screw machine, so as to solve the technical problems in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a cleaning device of overflow screw machine, includes screw machine body shell, be equipped with maintenance mechanism on the screw machine body shell, maintenance mechanism includes the casing, screw machine body shell passes this casing, the clearance bin outlet has been seted up to the below that screw machine body shell is located the casing, the below of casing is connected with row's hopper, one side of casing is equipped with the observation window.

Further, a gate valve is arranged on the cleaning discharge port.

Preferably, the gate valve and the observation window are on the same straight line.

Preferably, the observation window is provided with a cover plate hinged through a hinge.

Further, the illustrated housing is welded to the outer periphery of the screw body housing by means of welding.

Preferably, an observation hole is formed in the upper portion of the shell, and an opening is formed in the position, corresponding to the observation hole, of the shell of the screw machine body.

In summary, the utility model has the following beneficial effects: according to the utility model, the overhaul mechanism is arranged, when the overhaul is stopped, the cleaning discharge hole is opened to discharge dust, so that the dust and the materials in the overflow screw machine can be discharged, when the caking dust and the materials are blocked in normal production, the dust and the materials can be discharged or cleaned by using the discharge device, the load of the overflow screw machine is lightened, overload tripping is avoided, the dust and the materials are retained in the screw shaft and hardened due to moisture regain, and dust and sand are not easy to fly up and pollute the environment in cleaning.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.

Hereinafter, an embodiment of the present utility model will be described in accordance with its entire structure.

As shown in fig. 1-2, the utility model comprises a screw body shell 1, wherein an overhaul mechanism is arranged on the screw body shell 1, the overhaul mechanism comprises a shell 2, the screw body shell 1 penetrates through the shell 2, a cleaning discharge hole 5 is formed in the lower part of the screw body shell 1 in the shell 2, a discharge hopper 3 is connected below the shell 2, an observation window 7 is arranged on one side of the shell 2, a gate valve 6 is arranged on the cleaning discharge hole 5, the gate valve 6 and the observation window 7 are on the same straight line, a cover plate 8 hinged through a hinge is arranged at the observation window 7, the shell 2 is welded on the periphery of the screw body shell 2 in a welding mode, an observation hole 9 is formed above the shell 2, and an opening is formed in the screw body shell 2 corresponding to the observation hole 9.

According to the overflow screw machine, a gate valve 6 on a cleaning discharge hole 5 is in a closed state when the overflow screw machine works normally, an observation window 7 is also in a closed state, and materials are discharged from a discharge hole at the upper part of a shell 1 of the overflow screw machine through the driving of a screw shaft 10 and enter the next working procedure. When equipment is shut down for maintenance or if caking dust blocks the screw shaft 10 during normal production, the operation of the screw shaft 10 is stopped firstly, then the observation window 7 is opened, then the gate valve 6 is opened, then the overflow screw machine is started to enable the screw shaft 10 to operate, so that dust and caking retained in the screw machine body shell 1 can be discharged through the cleaning discharge port 3, whether the inside of the screw machine body shell 1 is cleaned or not can be observed through the observation hole 9, and after the cleaning is completed, the gate valve 5 and the observation hole 4 are sequentially closed, so that the normal operation of the overflow screw machine can be restored.

Although embodiments of the utility model have been shown and described, the detailed description is to be construed as exemplary only and is not limiting of the utility model as the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples, and modifications, substitutions, variations, etc. may be made in the embodiments as desired by those skilled in the art without departing from the principles and spirit of the utility model, provided that such modifications are within the scope of the appended claims.
