Description

Technical Field

[0001] The invention belongs to the field of sewage treatment equipment, and in particular relates to a device and method for efficient and rapid material dropping. Background Art

[0002] At present, the sludge deep dewatering system has been applied to various sewage treatment plants. In the field of municipal or industrial sewage, plate and frame filter presses have been widely used for dewatering. In engineering examples, the functionality of plate and frame filter press dewatering is also seen, and the moisture content is reduced to below 60%. However, in the actual operation process, human intervention is still required. Due to the inadequacy of front-end conditioning, the viscosity of the reagent, or the short blanking time. These factors will cause the material to remain on the filter cloth. In actual operation, manpower and intervention are required to deal with these residual blanks. In examples, it is often the case that the residual material is not cleaned up and continues to be put into use, thereby reducing the operating efficiency of the equipment and significantly reducing the processing capacity. The existing automatic blanking technology relies more on the low moisture content of the filter material, and falls by its own weight after forming. According to the current examples, human intervention not only brings certain safety hazards, but also increases labor costs. If human intervention is reduced, the operating efficiency of the equipment will be reduced. Therefore, it is very necessary to provide a device for efficient and fast blanking. Summary of the invention

[0003] The present invention provides a device and method for high-efficiency and rapid material dropping, which solves the problems in the prior art of materials not being easy to drop, labor costs being high and equipment operation efficiency being low.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] The invention can pull the filter plate to a specified position according to the hook plate machine, and then pull the filter cloth by rotating the metal shaft to make the material fall quickly.

[0006] The technical solution of the present invention is: an efficient and fast material dropping device, comprising filter plates arranged in parallel, the filter plates comprising a lower rotating shaft and an upper rotating shaft, filter cloths are clamped between adjacent filter plates through the lower rotating shaft and the upper rotating shaft, and the filter cloths can move along the lower rotating shaft and the upper rotating shaft.

[0007] Furthermore, it also includes an end rotating shaft arranged on the front end and / or rear end filter plate of the filter press, and the filter cloth passes through the end rotating shaft.

[0008] Furthermore, the end rotating shaft is connected to a motor, and the motor can drive the end rotating shaft to rotate, thereby pulling the filter cloth to flip.

[0009] Furthermore, when both the pressure plate and the thrust plate of the filter press are provided with an end rotating shaft, a certain length of the filter cloth at at least one end is reserved on the outside of the end rotating shaft; when the pressure plate or the thrust plate of the filter press is provided with an end rotating shaft, a certain length is reserved on the outside of the last rotating shaft through which the filter cloth passes at least at the other end away from the end rotating shaft.

[0010] Preferably, the reserved length of the filter cloth is equal to the height of the filter plate.

[0011] Furthermore, it also includes a hook plate machine that can be detachably matched with the filter plates, and adjacent filter plates are connected by connecting parts; the hook plate machine drives the filter plates to move, so that adjacent filter plates are in a clamped filtration state, or adjacent filter plates are separated in a unloading state.

[0012] Furthermore, the connecting piece between adjacent filter plates can be a metal chain, that is, the metal connecting piece falls down by its own weight and falls between the filter plate handles. The metal connecting piece can be in the form of a chain, a lead strip, etc. Alternatively, it can be connected by a metal winding and rewinding method. By setting a rewindable metal-type soft strip device on the filter plate, the metal soft strip is pulled out from the metal winding device when the filter plate is pulled apart, and the metal soft strip is rewound into the device when the filter plate is tightened. Furthermore, it can be connected by a spring, and the spring can be customized according to the width of the filter plate.

[0013] As another embodiment, the hook plate machine is fixedly connected to the end filter plate on one side of the compression plate of the filter press.

[0014] Furthermore, the length L of the connecting piece between the filter plates is at least twice the width W of the filter plates.

[0015] Furthermore, the upper rotating shaft is fixed on the filter plate.

[0016] Furthermore, a tension monitoring device is installed on the end rotating shaft to monitor the force applied to the filter cloth.

[0017] The filter cloth of the present invention is located between the filter plates. When the two filter plates are pulled apart, one side of the filter cloth naturally tilts due to the separation of the upper and lower axes, which facilitates the unloading of materials.

[0018] The present invention also discloses a method for efficient and rapid blanking, comprising the following steps:

[0019] Step 1: When the filter press starts to unload, the hook plate machine is connected to the end filter plate on one side of the filter press pressing plate, and the filter plate is pulled to move toward the rear end of the filter press. The adjacent filter plates in the filter press are connected by connecting pieces. With the traction of the hook plate machine, the filter plates are separated in sequence, and the materials fall off. When there is residual material, the second unloading waiting begins;

[0020] Step 2: The end rotating shaft at one end of the filter press rotates, pulling the filter cloth to flip, and the material falls with the movement of the filter cloth. The end rotating shaft rolls into the filter cloth and stops after reaching a certain length;

[0021] Step 3 is: the end rotating shaft at the other end of the filter press rotates, pulling the filter cloth to flip in the opposite direction, and stops after a certain length of the filter cloth is rolled in; the filter cloth flips and moves between the lower metal shaft and the upper metal shaft, and the material falls as the filter cloth flips.

[0022] Step 4: The filter cloth is in place and the equipment enters a ready-to-work state.

[0023] Furthermore, a tension monitoring device is provided on the end rotating shaft. When the resistance reaches a set value X, the filter cloth stops flipping and is driven by a motor on the end rotating shaft at the other end to flip in the reverse direction for a certain length and then flip forward again.

[0024] The present invention has the advantages of fast and efficient material dropping, reduces the cost and potential safety hazards caused by manual operation, and improves the operating efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
