Description

Technical Field

[0001] This utility model relates to the technical field of filter presses, and in particular to a three-in-one filter press that combines filtration, washing, and drying. Background Technology

[0002] A filter press is a device used for solid-liquid separation, widely used in chemical, pharmaceutical, food, and environmental protection industries. Its main working principle is to separate solids and liquids in a mixture using pressure. The specific process typically includes the following steps: feeding, filtration, washing, and drying. During the filtration, washing, and drying steps, a lifting agitator is usually required. The agitator needs to be raised and lowered during operation, which can easily lead to poor sealing of the agitator shaft, causing gas leakage. This not only affects the filtration effect of the material but also pollutes the air. Existing methods for solving gas leakage involve installing a sealing tube outside the agitator shaft inside the filter press to seal the interior. However, with the sealing tube inside the filter press, solid materials tend to accumulate there during agitation, making it prone to damage when compressed. Furthermore, the sealing tube inside the filter press is difficult to replace. Therefore, a filter press capable of external sealing is needed. Utility Model Content

[0003] The purpose of this invention is to solve the above problems and provide a three-in-one filter press that combines filtration, washing, and drying.

[0004] The technical solution of this utility model is: a three-in-one filter press for filtration, washing, and drying, comprising a reducer, a lifting agitator, and a tank. The lifting agitator extends from the top of the tank, and the reducer is powered by a drive motor. The reducer includes a hollow shaft, which serves as the power output end. The hollow shaft of the reducer drives the lifting agitator to rotate. The lifting agitator includes a lifting frame, a stirring shaft, and stirring blades disposed inside the tank. The stirring shaft is vertically arranged. The filter press also includes a sliding sealing device. The stirring shaft passes through the sliding sealing device. The top of the stirring shaft is rotatably engaged with the lifting frame. The hollow shaft of the reducer and the stirring shaft are engaged via a sliding key. A stirring hole is provided at the top of the tank. The bottom of the sliding sealing device is disposed outside the stirring hole. The bottom of the sliding sealing device is fixedly disposed outside the stirring hole, allowing for both sealing of the tank and lifting agitation.

[0005] Preferably, the sliding sealing device includes a sealing tube body; the sealing tube body is coaxially arranged with the stirring shaft; a sealing pad is provided inside the sealing tube body, the sealing pad is sleeved and fixed on the stirring shaft, and the sealing pad cooperates with the inner wall of the sealing tube body; the lower end of the sealing tube body is sealed to the top of the tank. When the hollow shaft of the reducer rotates, it drives the stirring shaft to rotate through the sliding key, the sealing pad rotates with the stirring shaft, and the sealing tube body remains stationary, thus sealing the sealing tube body while rotating.

[0006] The sliding sealing device and the stirring hole work together to form a sealed cavity inside, and the stirring shaft is set inside the cavity to ensure the sealing performance of the device.

[0007] Furthermore, the sealing tube is sealed to the top of the tank via a flange.

[0008] Furthermore, the lifting frame is horizontally positioned on top of the upper seal; a bearing seat is provided on the top of the lifting frame, and the top of the stirring shaft is rotatably engaged with the bearing seat. This allows the stirring shaft to rise and fall together with the bearing seat during rotation.

[0009] Furthermore, an oil seal structure is provided between the stirring shaft and the bearing housing to prevent dust from entering the bearing housing through the gap between the two, thereby improving the service life of the bearing housing.

[0010] Furthermore, the filter press also includes a fixed frame; the fixed frame is fixedly installed on the top of the tank; several lifting rods are vertically installed on the top of the fixed frame, and the lifting rods are connected to the lifting frame; the reducer is fixed on the top of the fixed frame. By driving the lifting rods, the position of the lifting frame can be adjusted.

[0011] Furthermore, a guide rod is fixed to the top of the fixed frame. The guide rod is vertically positioned and slides in conjunction with the lifting frame. The lifting frame slides along the guide rod as it moves up and down, increasing the stability of the device.

[0012] Preferably, the height of the sealing pad is matched with the lead of the lifting rod. When the lifting frame is raised or lowered, the sealing tube remains stationary, and the sealing pad rises and falls together with the stirring shaft. Matching the height of the sealing pad with the lead of the lifting rod ensures stable sealing.

[0013] Furthermore, the filter press also includes an outer shell; the tank is located inside the outer shell, and a uniform side heating chamber is provided between the outer side of the tank and the inner wall of the outer shell. The side heating chamber is provided with a side heat source inlet and a side heat source outlet respectively; a heating tube is provided on the outer bottom surface of the tank. The heating tube is arranged in a serpentine pattern to increase the heat exchange area, improve the drying speed and heat utilization rate. The two ends of the heating tube are provided with a lower heat source inlet and a lower heat source outlet respectively; heat sources are provided on the sides and bottom of the tank, which can accelerate the drying speed of the material inside the tank.

[0014] The tank is equipped with a filter plate inside, which covers the bottom of the tank and has a cavity between it and the bottom. The stirring blades are located above the filter plate. The stirring blades agitate the material and simultaneously perform pressure filtration, causing the liquid to flow out from the bottom of the filter plate, thus achieving solid-liquid separation.

[0015] Furthermore, the side heat source inlet and side heat source outlet are respectively located on the left and right sides of the outer shell. This allows heat to flow around the tank, increasing heat utilization efficiency.

[0016] Preferably, the top of the tank is provided with a discharge port and a gas inlet / outlet; the lower side of the tank is provided with a solid outlet; the bottom of the tank is provided with a liquid outlet; and a manhole is provided in the middle of the back of the tank. After work is completed, the tank can be cleaned and maintained through the manhole.

[0017] The beneficial effects of this utility model are as follows: The three-in-one filter press of this utility model, which combines filtration, washing, and drying, has the following advantages: 1. This utility model places the seal of the tank outside the tank, which can prevent the material inside the tank from accumulating on the sealing device during the stirring process, thus extending the service life of the sealing device and reducing material waste; 2. This utility model adopts a sliding sealing device with a telescopic structure connected to the tank body, which enables the overall sealing cavity of the device to be adjusted as the agitator rises and falls, thereby achieving dynamic sealing of the tank body.

[0022] The sliding sealing device 1 and the stirring hole 201 cooperate to form a sealed cavity inside, and the stirring shaft 301 is set inside the cavity to ensure the sealing performance of the device.

[0023] The sealing pipe 12 is sealed to the top of the tank 02 via a flange.

[0024] The lifting frame 302 is horizontally positioned on top of the upper seal; a bearing seat 306 is provided on the top of the lifting frame 302, and the top of the stirring shaft 301 is rotatably engaged with the bearing seat 306. This allows the stirring shaft 301 to rise and fall together with the bearing seat 306 when rotating.

[0025] An oil seal structure is provided between the stirring shaft 301 and the bearing housing 306 to prevent dust from entering the bearing housing 306 through the gap between the two, thereby improving the service life of the bearing housing 306.
