Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a slurry filter. Background Art

[0002] The slurry filter is a kind of equipment widely used in the fields of chemical industry, pharmaceutical industry, food industry, environmental protection, etc. It is mainly used to separate the solid and liquid of the slurry, remove the impurities and particles therein, and obtain the clear filtrate. This equipment plays an important role in improving product quality, protecting the environment, and saving energy and reducing emissions.

[0003] In recent years, with the continuous emergence of new materials and new processes, the technology of slurry filters has also been continuously upgraded. For example, some advanced filter materials, such as ceramic filter plates and polymer filter membranes, are widely used in slurry filters. These materials have the advantages of high flux, high retention rate, and easy cleaning, which greatly improves the filtering effect and service life.

[0004] When existing slurry filters filter slurry containing salt substances, in order to ensure the filtration efficiency, the filter residue on the filter screen needs to be removed in time. However, it is generally inconvenient to remove the filter residue in a closed filter. Stopping the filter to clean the filter residue will reduce the filtration efficiency of the filter.

[0005] Therefore, it is necessary to provide a slurry filter to solve the above technical problems. Utility Model Content

[0006] The utility model aims to provide a slurry filter, which can make the filter residues produced in the filtering process be discharged from the filter tube in time, avoid accumulation on the filter net, affect the filtering effect of subsequent slurry, and improve the filtering efficiency of the device.

[0007] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a slurry filter comprises a collecting box, a filter tube is arranged on the top of the collecting box, a feed pipe is fixedly connected to the top of the filter tube, an extrusion roller is rotatably connected inside the filter tube, a motor is fixedly installed on the side wall at one end of the filter tube, an output end of the motor passes through the filter tube and is fixedly connected to the extrusion roller, a drain pipe is fixedly connected to the bottom of the filter tube away from the end of the feed pipe, the bottom end of the drain pipe is fixedly connected to the collecting box, a filter screen is arranged at the connection between the drain pipe and the filter tube, a slag outlet is opened on the top of the side wall at the end of the filter tube away from the motor, a filter residue box is fixedly connected to the top of the collecting box on the side close to the slag outlet, the filter tube is fixedly connected to the side wall of the filter residue box, and the slag outlet is arranged inside the filter residue box.

[0008] By adopting the above technical solution, the filter residue generated during the filtration process can be promptly removed from the filter tube through the device to avoid accumulation on the filter net, affecting the subsequent filtration effect of the slurry, and improving the filtration efficiency of the device.

[0009] The utility model is further configured as follows: a feed hopper is fixedly installed on the top of the feed pipe.

[0010] By adopting the above technical solution, the feed port is enlarged through the feed hopper, so that the slurry splashing out when the filtered slurry is poured into the feed pipe is avoided.

[0011] The utility model is further configured as follows: a support frame is fixedly connected to the bottom of one end of the filter tube close to the motor, and the bottom end of the support frame is fixedly connected to the top of the collection box.

[0012] By adopting the above technical solution, the filter tube is supported by the support frame, thereby increasing the stability of the filter tube during operation.

[0013] The utility model is further configured as follows: a sealing door is rotatably connected to the side wall of the filter residue box, and a handle is fixedly installed on the side wall of the sealing door.

[0014] By adopting the above technical solution, the sealed door is opened by a handle to remove the filter residue produced by the filtration.

[0015] The utility model is further configured as follows: a discharge port is fixedly installed at the bottom of the side wall of the collection box.

[0016] By adopting the above technical solution, the liquid obtained by filtration is taken out through the discharge port and collected.

[0017] The utility model is further configured as follows: a base is fixedly installed at the bottom of the collection box, rollers are fixedly connected to the four corners of the bottom of the base, and a push handle is fixedly installed on one side of the top of the base.

[0018] By adopting the above technical solution, the rollers and push handle installed on the base can facilitate the reverse movement of the entire device, thereby improving the mobility of the device.

[0019] The utility model is further configured as follows: adjusting screws are threadedly connected to both sides of the top of the base, knobs are fixedly connected to the tops of the two adjusting screws, supporting plates are rotatably connected to the bottoms of the two adjusting screws, and rubber pads are fixedly installed on the bottoms of the two supporting plates.

[0020] By adopting the above technical solution, after the device moves to the specified position, the adjusting screw is rotated by turning the knob, and the rotation of the adjusting screw drives the support plate to continue to descend. When the support plate contacts the ground, the adjusting screw is then rotated to squeeze the support plate and the ground to fix the device. The rubber pad is used to increase the friction between the support plate and the ground.

[0021] In summary, the utility model has the following beneficial effects: when filtering slurry containing salt substances, the slurry is added to the filter tube through the feed pipe, and then the motor is turned on. The output end of the motor drives the squeezing roller to rotate slowly to squeeze and transmit the slurry added to the inside of the filter tube, so as to separate the liquid from the solid impurities in the slurry. When the liquid in the slurry passes through the discharge pipe, it enters the collection box through the discharge pipe and is stored. When the solid impurities pass through the discharge pipe, they are blocked by the filter screen and cannot pass through. Under the action of the squeezing roller, they are squeezed and transmitted to the slag outlet. As the solid impurities continue to accumulate, they are finally squeezed out at the slag outlet, enter the filter residue box and are collected. Through this device, the filter residue generated in the filtration process can be promptly discharged from the filter tube to avoid accumulation on the filter screen, which affects the subsequent filtration effect of the slurry and improves the filtration efficiency of the device.
