Description

Technical Field

[0001] This utility model belongs to the technical field of rice processing equipment, and in particular relates to a hydrochloric acid sludge dewatering device. Background Technology

[0002] In current wastewater treatment processes, flocculation sedimentation is commonly used. This method typically involves adding flocculants to the wastewater, causing fine particles and colloidal substances to form large flocs. Through settling and stratification, the flocs settle to the bottom layer and are removed through separation, thus purifying the water. While flocculation sedimentation is a relatively effective method for removing impurities and pollutants from water, it generates a large amount of sludge, which is difficult to dry due to its high water content. Current technology typically uses plate and frame filter presses to remove the water from the sludge.

[0003] Existing filter presses require manual removal of the pressed mud cake after each filter press, which is inefficient and wastes manpower. Utility Model Content

[0004] This invention provides a hydrochloric acid sludge filter press, which aims to solve the problem that existing filter presses require manual removal of the pressed sludge cake after each filtration, resulting in low efficiency and wasted manpower.

[0005] This utility model is implemented as follows: a hydrochloric acid sludge filter press includes a filter press box, a cylinder, a pressure plate, a feed pipe, a drain pipe, and a controller. The outer wall of the filter press box is connected to an equipment frame, and a motor is fixedly connected to the outer wall of the equipment frame. The output end of the motor is fixedly connected to a bidirectional screw slide, and a slider is threadedly connected to the outer wall of the bidirectional screw slide. Two sliders are symmetrically distributed along the vertical center line of the bidirectional screw slide, and the sliders are slidably connected to the equipment frame. One end of a support rod is hinged to the outer wall of the slider. A push frame is movably connected inside the equipment frame, and the other end of the slider is hinged to the push frame. A filter press groove matching the pressure plate is opened on the upper right surface of the push frame, and filter screens are respectively provided on the outer walls of both sides of the filter press groove. A cover plate is fixedly connected to the outer wall of the right end of the push frame. The cylinder, the motor, and the controller are electrically connected.

[0006] Preferably, the outer wall of the push frame is provided with a slot that matches the filter screen plate.

[0007] Preferably, the feed pipes are symmetrically distributed along the vertical center line of the filter press.

[0008] Preferably, a baffle is fixedly connected to the upper surface of the pressure plate.

[0009] Preferably, a weight sensor is fixedly connected to the outer wall of the cover plate, and the weight sensor is electrically connected to the controller.

[0010] Compared with the prior art, the embodiments of this application have the following main advantages:

[0011] The feed pipe is connected to a peristaltic pump. The pump injects sludge into the filter press chamber through the feed pipe. The extension of the cylinder's telescopic end causes the pressure plate to squeeze the sludge below. The pressure within the filter press chamber causes water to be released through the filter screen. This water is then discharged through the drain pipe. After the sludge is filtered, the cylinder's telescopic end retracts, and the motor output drives the bidirectional screw slide to rotate. This rotation moves the two sliders away from each other, causing the support rod to push the push frame to the right. This movement causes the filter press chamber to protrude outside the filter press chamber, facilitating the removal of the filter cake from the chamber by gravity. This eliminates the need for manual removal of the pressed cake, improving equipment efficiency. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model provides a hydrochloric acid sludge filter press device, such as... Figure 1-5 As shown, the system includes a filter press 1, a cylinder 2, a pressure plate 3, a feed pipe 4, a drain pipe 16, and a controller. The outer wall of the filter press 1 is connected to an equipment frame 5, and a motor 6 is fixedly connected to the outer wall of the equipment frame 5. The output end of the motor 6 is fixedly connected to a bidirectional screw slide 7, and a slider 8 is threadedly connected to the outer wall of the bidirectional screw slide 7. The two sliders 8 are symmetrically distributed along the vertical center line of the bidirectional screw slide 7, and the sliders 8 are slidably connected to the equipment frame 5. One end of a support rod 9 is hinged to the outer wall of the slider 8. A push frame 10 is movably connected inside the equipment frame 5, and the other end of the slider 8 is hinged to the push frame 10. A filter press groove 11 matching the pressure plate 3 is opened on the upper right surface of the push frame 10, and filter screen plates 12 are respectively provided on the outer walls of both sides of the filter press groove 11. A cover plate 13 is fixedly connected to the outer wall of the right end of the push frame 10. The cylinder 2 and the motor 6 are electrically connected to the controller.

[0021] It should be noted that existing filter press devices require manual removal of the pressed sludge cake after each filtration, which is inefficient and wastes manpower. Therefore, to solve this problem, the feed pipe 4 in this solution is connected to a peristaltic pump. The peristaltic pump injects sludge into the filter press chamber 1 through the feed pipe 4. The extension of the cylinder 2's telescopic end allows the pressure plate 3 to squeeze the sludge below. The pressure on the sludge within the filter press tank 11 causes the water in the sludge to be released through the filter screen 12. The water extracted from the filter screen 12 is discharged through the drain pipe 16. After the sludge is filtered, the telescopic end of the cylinder 2 retracts. Driven by the output end of the motor 6, the bidirectional screw slide 7 can rotate. The rotation of the bidirectional screw slide 7 can cause the two sliders 8 to move away from each other, thereby causing the support rod 9 to push the push frame 10 to move to the right. The movement of the push frame 10 will cause the filter press trough 11 to protrude from the outside of the filter press box 1, thus facilitating the sludge cake in the filter press trough 11 to be removed from the filter press trough 11 by gravity. There is no need to manually remove the pressed sludge cake, which improves the working efficiency of the equipment.

[0022] In a further preferred embodiment of this utility model, such as Figure 4As shown, the outer wall of the push frame 10 has a slot that matches the filter screen plate 12.

[0023] In this embodiment, the filter screen 12 and the push frame 10 are connected by an insertion joint, which facilitates the replacement of the filter screen 12 by personnel.

[0024] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the feed pipe 4 is symmetrically distributed along the vertical center line of the filter press 1.

[0025] In this embodiment, the efficiency of sludge entering the filter press box 1 is improved by using two feed pipes 4.

[0026] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a baffle 15 is fixedly connected to the upper surface of the pressure plate 3.

[0027] In this embodiment, when the pressure plate 3 descends, the sludge in the feed pipe 4 will drip onto the upper surface of the pressure plate 3. The baffle 15 shields the feed pipe 4 when the pressure plate 3 descends, preventing the sludge in the feed pipe 4 from dripping onto the pressure plate 3.

[0028] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a weight sensor 14 is fixedly connected to the outer wall of the cover plate 13, and the weight sensor 14 is electrically connected to the controller.

[0029] In this embodiment, the pressure between the cover plate 13 and the filter press 1 is detected by the weight sensor 14. When the pressure between the cover plate 13 and the filter press 1 reaches the set value, the weight sensor 14 sends a signal to the controller. The controller receives the signal from the weight sensor 14 and controls the motor 6 to stop working, ensuring that the filter press 11 is located below the pressure plate 3.
