Description

Technical Field

[0001] This utility model relates to the field of centrifuges, and more specifically, to a centrifuge feed flow control device. Background Technology

[0002] Centrifuges are machines that use centrifugal force to separate the components in a mixture of liquids and solid particles or liquids and liquids. Centrifuges are often used in wastewater treatment in factories, and their workload is too large in the daily wastewater treatment process.

[0003] A search revealed an existing patent (application number: CN201711062615.7) disclosing a horizontal centrifuge. The centrifuge drum has a material outlet connected to its tail end via a threaded structure, and a material inlet pipe connected to one side of its head end. A rotating motor is suspended from the head end of the centrifuge drum via a bracket. A vortex-shaped spiral drum is mounted at the rotor end of the rotating motor. The side wall of the centrifuge drum has mounting holes, and a filter screen structure layer is inserted inside these holes. The inner side wall of the centrifuge drum is also lined with a cylinder filter screen layer, which does not coexist with the filter screen structure layer. This horizontal centrifuge improves the efficiency of centrifugation and material filtration by combining a swirling water outlet structure with a plug-in multi-layer filter screen structure. The use of a filter screen structure layer that can be installed horizontally and vertically, along with the cylinder filter screen layer installation method, achieves multi-directional separation and discharge of materials, broadening the centrifuge's applicability and enhancing the filtration effect. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] The existing horizontal centrifuges do not have a flow control device at the feed port. When the workload is large or it is difficult to process all the wastewater fed into the centrifuge quickly, if the flow rate of wastewater entering the centrifuge is not controlled, it will increase the workload of the centrifuge, thereby affecting the working efficiency and the decontamination and separation effect of the centrifuge.

[0005] Therefore, a centrifuge feed flow control device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a centrifuge feed flow control device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a centrifuge feed flow control device, comprising a centrifuge body, a feed pipe connected to one end of the centrifuge body, a control connection block connected to the feed pipe, an installation connection block connected to one side of the control connection block, and a motor mounting platform connected to the side of the installation connection block away from the control connection block, and a flow control device connected to the top of the motor mounting platform;

[0008] The flow control device includes a control motor, a transmission connection box, and a telescopic connection box. The control motor and the telescopic connection box are both connected to the side of the transmission connection box near the mounting connection block. The bottom of the centrifuge body is provided with a water outlet pipe and a wastewater outlet pipe, and a flow meter is connected to both the water outlet pipe and the wastewater outlet pipe.

[0009] Preferably, a motor controller is connected to one side of the control motor, and a drive wheel is connected to one end of the control motor, with the drive wheel housed inside the transmission connection box.

[0010] Preferably, a transmission wheel is provided inside the transmission connection box, and a transmission belt connects the drive wheel and the transmission wheel, and a transmission screw is provided inside the telescopic connection box.

[0012] Preferably, a connecting sleeve is connected to the side of the transmission connecting block near the control connecting block, and a control valve core is connected to the connecting sleeve away from the transmission connecting block, and the control valve core is disposed inside the control connecting block.

[0013] Preferably, a connecting groove is provided at the connection between the control valve core and the control connecting block, and a sealing gasket is provided on the inner side of the connecting groove.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with the prior art, this centrifuge feed flow control device allows the wastewater entering the centrifuge body to be treated by centrifugation. The purified water is discharged through the drain pipe, while the turbid pollutants are discharged through the wastewater outlet pipe. During the discharge process, the flow rate is monitored by a flow meter, and the flow data from the flow meters on the water outlet pipe and the wastewater outlet pipe can be used for control. Thus, the flow rate of the incoming flow rate can be adjusted in real time by adjusting the discharge rate, making the centrifuge's sewage discharge work more efficient.

[0016] 2. Compared with the prior art, this centrifuge feed flow control device controls the motor steps by having the motor controller drive the drive wheel to rotate. During the rotation of the drive wheel, the drive wheel drives the transmission wheel to rotate via the transmission belt. During the rotation of the transmission wheel, the transmission screw connected inside it rotates together, and during the rotation, the transmission connecting block connected to it moves along the rotation direction of the transmission screw. During the movement of the transmission connecting block, the connecting sleeve and the control valve core connected to the connecting sleeve move, thereby changing the size of the channel inside the control connecting block during the movement of the control valve core, and thus changing the flow rate of sewage flowing through the control connecting block, making the flow control more precise.

The drive wheel 712 is located inside the transmission connection box 72. Furthermore, the control motor 711 is a stepper motor, and the number of steps of the control motor 711 is controlled by the motor controller 711 according to the flow data of the flow meter 5 on the water outlet pipe 3 and the sewage outlet pipe 4. This allows the flow rate of the inlet to be adjusted in real time by adjusting the discharge volume, making the sewage discharge of the centrifuge more efficient.

Both ends of the transmission screw 731 rotate within the connecting bearings 723 in the transmission connecting box 72 and the telescopic connecting box 73, respectively. During the rotation of the transmission screw 731, the connected transmission connecting block 741 moves along the rotation direction of the transmission screw 731.
