A water treatment sludge filter press device

Abstract

This utility model belongs to the field of filter press technology, and in particular to a water treatment sludge filter press device. It includes a filter press body with a sludge inlet at its lower end. A decontamination mechanism is installed on the lower surface of the sludge inlet. The decontamination mechanism includes an air extraction pipe, and a reinforcing pipe, shaped as a triangular prism, is fixedly sleeved on the outer surface of the air extraction pipe. This water treatment sludge filter press device, by installing a decontamination mechanism at the lower end of the sludge inlet of the filter press body, uses the air extraction pipe in the decontamination mechanism to suction the filtered sludge cake. This allows small particles of sludge that are easily splashed from the surface and edges of the sludge cake to be directionally removed, preventing environmental pollution. Simultaneously, the reinforcing pipe and crushing rod horizontally at the lower end of the sludge inlet intercept the sludge, causing it to impact the surface of the crushing rod for buffering and crushing. This reduces the impact force of large pieces of sludge falling onto the conveying equipment below the filter press body, thus protecting the equipment.

Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a water treatment sludge filter press device. Background Technology

[0002] During operation, a filter press removes water from sludge, causing it to coagulate into cake-like sludge. This cake then slides down under gravity as the filter press extends. Current industrial designs typically use a conveyor belt to collect and transport the falling sludge. However, during this process, some cakes break apart due to equipment vibration and impacts from the sludge against the conveyor belt, generating numerous small particles of impurities. The larger the sludge volume, the more impurities are produced. These particles scatter across the conveyor belt and workshop floor, impacting the working environment and potentially causing equipment damage and hindering operation. Summary of the Invention

[0003] To address the technical problem of existing sludge filter presses lacking a sludge removal mechanism during sludge feeding, this utility model proposes a water treatment sludge filter press.

[0004] The present invention discloses a sludge dewatering device for water treatment, comprising a filter press body, a sludge inlet at the lower end of the filter press body, a decontamination mechanism installed on the lower surface of the sludge inlet, the decontamination mechanism comprising an air extraction pipe, and a reinforcing pipe fixedly sleeved on the outer surface of the air extraction pipe, the reinforcing pipe being triangular prism-shaped.

[0005] Preferably, the lower surface of the reinforcing tube is provided with a dust suction hole, and a plurality of the dust suction holes are arranged in a linear array on the lower surface of the reinforcing tube, and the upper end of the dust suction hole is connected to the interior of the suction tube.

[0006] By utilizing the above technical solution, the suction hole is located at the lower end of the air extraction pipe, thus preventing the falling sludge from directly clogging the suction hole.

[0007] Preferably, a breaking rod is movably sleeved on the outer surface of the reinforcing tube. The breaking rod is in the shape of a hollow triangular prism, and an installation hole is opened on the lower surface of the breaking rod. The distribution of the plurality of installation holes is aligned with the distribution of the plurality of dust suction holes.

[0008] The above technical solution utilizes the upward-pointing sharp edges of the crushing rod to facilitate the crushing of falling sludge. Limiting structures can also be installed at both ends of the crushing rod to prevent excessive misalignment between the mounting hole and the dust suction hole during the shaking process.

[0009] Preferably, a spring piece is fixedly connected to the inner wall of the mounting hole, and the spring piece is in the shape of a semi-disc.

[0010] The above technical solution utilizes a spring to align with the suction hole, which facilitates the vibration of the spring by airflow and impurities when suctioning air from the suction hole.

[0011] Preferably, the two ends of the reinforcing pipe are fixedly connected to mounting frames, the mounting frames are rectangular, and the upper surface of the mounting frames is fixedly connected to the lower surface of the sludge outlet.

[0012] The above technical solution utilizes a mounting frame to install the cleaning mechanism while simultaneously creating a relatively enclosed environment, which facilitates the accumulation of impurities.

[0013] Preferably, an exhaust fan is fixedly connected to the outer surface of the mounting frame, and the air inlet of the exhaust fan is connected to the interior of the exhaust pipe.

[0014] The above technical solution utilizes an exhaust fan to power the decontamination mechanism, thereby facilitating the directional removal of impurities. The exhaust fan can be an industrial medium-pressure blower model CX-75S, and the specific model can be adjusted according to the specifications of the filter press body.

[0015] The beneficial effects of this utility model are as follows: By installing a desludge removal mechanism at the lower end of the sludge inlet of the filter press body, the desludge cake after pressing is sucked up by the air extraction pipe in the desludge removal mechanism. This allows small particles of mud and impurities that are easily splashed on the surface and edges of the mud cake to be directionally removed, thus avoiding environmental pollution. At the same time, the sludge is intercepted by the reinforcement pipe and crushing rod at the lower end of the sludge inlet. The sludge is buffered and crushed by impacting the surface of the crushing rod, thereby reducing the impact force of large pieces of sludge falling on the conveying equipment below the filter press body, thus protecting the equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4 A water treatment sludge filter press device includes a filter press body 1. A sludge inlet 11 is provided at the lower end of the filter press body 1. A sludge removal mechanism is installed on the lower surface of the sludge inlet 11. The sludge removal mechanism includes an air extraction pipe 2. A reinforcing pipe 21 is fixedly sleeved on the outer surface of the air extraction pipe 2. The reinforcing pipe 21 is triangular prism shaped.

[0020] To crush the sludge, a suction hole 22 is provided on the lower surface of the reinforcing pipe 21. Multiple suction holes 22 are arranged in a linear array on the lower surface of the reinforcing pipe 21. The upper end of the suction hole 22 is connected to the interior of the suction pipe 2. By using the location of the suction hole 22 at the lower end of the suction pipe 2, it is easy to avoid the falling sludge directly clogging the suction hole 22. A crushing rod 23 is movably sleeved on the outer surface of the reinforcing pipe 21. The crushing rod 23 is hollow triangular prism. The lower surface of the crushing rod 23 is provided with mounting holes. The distribution of multiple mounting holes is aligned with the distribution of multiple suction holes 22. By using the sharp edge of the crushing rod 23 to face upward, it is easy to crush the falling sludge through the crushing rod 23. Limiting structures can also be installed at both ends of the crushing rod 23 to avoid excessive offset between the mounting holes and the suction holes 22 during the shaking process of the crushing rod 23.

[0021] To extract impurities, a spring sheet 24 is fixedly connected to the inner wall of the mounting hole. The spring sheet 24 is semi-disc shaped and is aligned with the dust suction hole 22. When the dust suction hole 22 is used for suction, the airflow and impurities cause the spring sheet 24 to vibrate. The two ends of the reinforcing tube 21 are fixedly connected to the mounting frame 25. The mounting frame 25 is rectangular and its upper surface is fixedly connected to the lower surface of the sludge port 11. While installing the cleaning mechanism, the mounting frame 25 creates a relatively closed environment, which facilitates the accumulation of impurities. The outer surface of the mounting frame 25 is fixedly connected to the exhaust fan 26. The air inlet of the exhaust fan 26 is connected to the inside of the exhaust pipe 2. The exhaust fan 26 provides power to the cleaning mechanism, which facilitates the directional extraction of impurities. The exhaust fan 26 can be an industrial medium-pressure blower CX-75S model, which can be adjusted according to the specifications of the filter press body 1.

[0022] By installing a decontamination mechanism at the lower end of the sludge inlet 11 of the filter press body 1, the decontamination mechanism uses the suction pipe 2 in the decontamination mechanism to suck up the sludge cake after filtration, so that small particles of mud impurities that are easily splashed in the sludge cake are directionally extracted to avoid environmental pollution. At the same time, the sludge is intercepted by the reinforcing pipe 21 and the crushing rod 23 at the lower end of the sludge inlet 11, so that the sludge impacts the surface of the crushing rod 23 for buffering and crushing, thereby reducing the impact force of large pieces of sludge falling on the conveying equipment below the filter press body 1, thus protecting the equipment.

[0023] Working principle: When in use, start the exhaust fan 26 and the filter press body 1. After the filter press body 1 filters the water in the sludge, the filter press extends and discharges the squeezed sludge downwards. The sludge enters the mounting frame 25 and impacts the surface of the crushing rod 23, breaking the sludge and producing small mud particles. The exhaust fan 26 sucks the mud particles through the exhaust pipe 2 and the dust suction hole 22.

[0024] As the airflow enters the suction hole 22 through the mounting hole, the airflow and impurities cause the spring 24 to vibrate, and the spring 24 causes the crushing rod 23 to vibrate. The contact between the sludge and the surface of the crushing rod 23 becomes more dispersed, reducing the impact that causes wear on the surface of the crushing rod 23.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
