Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solid-liquid separation equipment, and more specifically to a solid-liquid separation type filter press equipment. Background Art
[0002] Solid-liquid separation technology is a common process that involves the separation of two phases, namely solid and liquid, from a suspension. It is used in many production processes to recover valuable solid or liquid phases, or both.
[0003] The existing filter press equipment used in the laboratory is a manual hydraulic filter press equipment, which achieves the effect of solid-liquid separation by adding a steel plate at the bottom of the hydraulic rod to squeeze the solid-liquid mixture in the filter bag. However, since the filter bag is accumulated at the bottom of the perforated container, a large amount of solid-liquid mixture is accumulated at the bottom of the container during the process of the hydraulic rod pushing the steel plate to squeeze. At the same time, since the contact area between the steel plate and the solid-liquid mixture is small, the solid-liquid mixture located at the center of the filter bag cannot be fully squeezed, resulting in a poor solid-liquid separation effect. The method of separating the solid-liquid mixture in batches reduces the work efficiency. At the same time, due to the increase in the number of solid-liquid mixture separation operations, the work content becomes more cumbersome.
[0004] Therefore, a new filter press equipment is needed to satisfy the requirement of sufficient solid-liquid separation operation on the solid-liquid mixture. Utility Model Content
[0005] The purpose of the utility model is to provide a solid-liquid separation filter press equipment to solve the problems raised in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides a solid-liquid separation type filter press equipment, comprising a first shell, a support frame and a second shell are arranged in the first shell, the support frame is connected to the side wall of the first shell, the second shell is arranged on the support frame, and an extrusion device is arranged in the second shell, the extrusion device comprises a motor, two first push plates and two second push plates;
[0007] The bottom of the second shell is recessed with an extension portion, and the motor is installed in the extension portion. A threaded rod is fixedly connected to the output end of the motor, and a threaded sleeve is sleeved and threadedly connected on the threaded rod. Each first push plate and each second push plate are connected to the threaded sleeve through N connecting rods, respectively, and N is greater than or equal to 2.
[0008] Furthermore, the two first push plates and the two second push plates are both arc-shaped, the two first push plates are axially symmetrically arranged along the threaded sleeve, the two second push plates are axially symmetrically arranged along the threaded sleeve, both ends of the two first push plates are provided with grooves inwardly, and the two ends of the two second push plates are respectively inserted into the grooves at both ends of the two first push plates; the two first push plates and the two second push plates form a ring.
[0009] Furthermore, a limit block is fixedly connected to the surface of the two first push plates and the two second push plates opposite to the threaded sleeve, and a limit groove is opened on the bottom surface of the internal space of the second shell and at the corresponding position of each limit block, and each limit block is slidably connected to the corresponding limit groove.
[0010] Furthermore, the support frame is cross-shaped, and a through groove matched with the extension portion is provided at the center of the support frame.
[0011] Furthermore, a slider is fixedly connected to each of the four end points of the support frame, and a mounting block corresponding to each slider is fixedly connected to the inner wall of the first shell.

[0016] Furthermore, the limiting groove and the limiting block are both in an inverted T shape.
[0017] Compared with the prior art, the utility model has the following significant advantages:
[0018] The method of using a motor in the extrusion device to drive the threaded sleeve to push the first push plate and the second push plate replaces the existing manual hydraulic rod, thereby improving the efficiency of extruding the solid-liquid mixture. At the same time, compared with the method of extruding the solid-liquid mixture in the filter bag downward by a steel plate in the prior art, the filter press equipment increases the contact area between the filter bag and the filter bag by setting the filter bag in a ring shape and sleeved it on the outer surface of the ring formed by the first push plate and the second push plate.

DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0024] like Figure 1-3 As shown, the utility model provides a solid-liquid separation type filter press device, including a first shell 1, a support frame 3 and a second shell 2 are arranged in the first shell 1, the support frame 3 is connected to the side wall of the first shell 1, the second shell 2 is arranged on the support frame 3, and an extrusion device 4 is arranged in the second shell 2, and the extrusion device 4 includes a motor 41, two first push plates 42 and two second push plates 43;
[0025] An extension portion 21 is recessed at the bottom of the second shell 2, and a motor 41 is installed in the extension portion 21. A threaded rod 44 is fixedly connected to the output end of the motor 41, and a threaded sleeve 45 is sleeved and threadedly connected on the threaded rod 44. Each first push plate 42 and each second push plate 43 are connected to the threaded sleeve 45 through N connecting rods 46, respectively, and N is greater than or equal to 2.
[0026] In one embodiment, the two first push plates 42 and the two second push plates 43 are both arc-shaped, the two first push plates 42 are axially symmetrically arranged along the threaded sleeve 45, the two second push plates 43 are axially symmetrically arranged along the threaded sleeve 45, both ends of the two first push plates 42 are provided with grooves inwardly, and the two ends of the two second push plates 43 are respectively inserted into the grooves at both ends of the two first push plates 42; the two first push plates 42 and the two second push plates 43 form a ring.
[0027] In one embodiment, a limit block 5 is fixedly connected to the surfaces of the two first push plates 42 and the two second push plates 43 opposite to the threaded sleeve 45, and a limit groove 6 is opened at the bottom surface of the internal space of the second shell 2 and at the corresponding position of each limit block 5, and each limit block 5 is slidably connected to the corresponding limit groove 6.
[0028] In one embodiment, the limiting groove 6 and the limiting block 5 are both in an inverted T shape.
[0029] In one embodiment, the filter press device further includes an annular filter bag, which is disposed in the second housing 2 and sleeved on the annular periphery surrounded by the first push plate 42 and the second push plate 43 .
[0030] When in use, first install the second housing 2 in the first housing 1, then place the filter bag containing the solid-liquid mixture in the second housing 2. After the filter bag is placed, start the motor 41, and the motor 41 drives the threaded rod 44 to rotate. Under the cooperation between the limit block 5 and the limit groove 6, the threaded sleeve 45 sleeved on the threaded rod 44 can be limited, so that it moves vertically along the center line of the threaded rod 44 during the rotation of the threaded rod 44. During the downward movement of the threaded sleeve 45, the two first push plates 42 and the two second push plates 43 are pushed along the limit groove 6 to the inner wall of the second housing 2 by the connecting rod 46, so that the solid-liquid mixture in the filter bag is squeezed by the first push plate 42 and the second push plate 43 in cooperation with the inner wall of the second housing 2, thereby achieving the effect of solid-liquid separation. Because the filter bag is set to be annular, the contact area between the first push plate 42 and the second push plate 43 and the filter bag during the solid-liquid separation process is increased, thereby effectively improving the solid-liquid separation efficiency. At the same time, due to the influence of increasing the contact area, the solid-liquid mixture in the filter bag will not accumulate in one place. Compared with the previous method of filtration through manual hydraulic rods, the time used for solid-liquid separation is reduced, and the work efficiency is further improved.
[0031] It should be noted that when placing the filter bag, the filter bag needs to be placed in the space between the second housing 2 and the first push plate 42 and the second push plate 43 .
[0032] After completing the squeezing of the solid-liquid mixture in the filter bag, the staff controls the motor 41 to drive the threaded rod 44 to reverse. At this time, the threaded sleeve 45 begins to rise at a uniform speed, and drives all the connecting rods 46 connected to it to be recovered. At this time, the two first push plates 42 and the two second push plates 43 move toward the threaded rod 44 at a uniform speed, and the two ends of the two second push plates 43 are recovered into the grooves at the two ends of the two first push plates 42 at a uniform speed, thereby gradually canceling the squeezing effect on the filter bag, and then the filter bag is taken out to complete the filter pressing operation of the solid-liquid mixture.
[0033] In one embodiment, the support frame 3 is cross-shaped, and a through slot 31 matching the extension portion 21 is provided at the center of the support frame 3. When the second housing 2 is installed, the extension portion 21 is inserted into the through slot 31 on the support frame 3, thereby fixing and limiting the second housing 2.
[0034] In one embodiment, four end points of the support frame 3 are connected to the inner wall of the first shell 1 .
[0035] In one embodiment, a slider 32 is fixedly connected to each of the four end points of the support frame 3, and a mounting block 8 corresponding to each slider 32 is fixedly connected to the inner wall of the first shell 1. Each mounting block 8 is provided with a slide groove, and one end of each slide groove extends to the top of the mounting block 8. Each slider 32 is slidably connected to the slide groove of the corresponding mounting block 8, so as to improve the stability of the second shell 2 and the extrusion device 4.
[0036] In one embodiment, a truncated cone is provided on the bottom wall of the first housing 1, and a placement groove matching the bottom of the extension 21 is recessed on the top of the truncated cone. A pin connected to the motor 41 is installed at the bottom of the extension 21, and a socket matching the pin is provided in the placement groove. An electrical connection line is also provided on the socket, and the other end of the electrical connection line passes through the truncated cone and the first housing 1 in turn, and a plug is installed to supply power to the motor 41. The truncated cone can effectively prevent the liquid phase filtered out from the filter press from contacting the electrical connection when the filter press is working, and the truncated cone can assist the support frame 3 in fixing and limiting the second housing 2 and the extrusion device 4, further improving the stability of the filter press.
[0037] In one embodiment, a switch connected to the motor 41 is further provided on the first housing 1 to control the start and stop of the motor 41 .
[0038] In one embodiment, an annular rubber pad is added to the top of the truncated cone, and the inner circumference of the rubber pad is matched with the extension part 21. When the extension part 21 is inserted into the placement groove, its outer surface contacts the inner circumference of the rubber pad.
[0039] In one embodiment, when the bottom of the extension portion 21 is completely inserted into the placement groove, the bottom surface of the second housing 2 is in contact with the upper surface of the support frame 3 .
[0040] In one embodiment, an annular baffle 7 is fixedly connected to the bottom of the internal space of the second housing 2 and at the opening of the extension portion 21. During the solid-liquid separation process of the filter press, the annular baffle 7 can effectively prevent the liquid phase filtered out from flowing into the extension portion 21, thereby ensuring the normal operation of the filter press and avoiding damage caused by direct contact between the motor 41 and the liquid phase.
[0041] In one embodiment, a plurality of through holes are provided on the side wall of the second shell 2 and the position surrounded by the non-annular baffle 7 at the bottom of the second shell 2. The through holes effectively ensure that the liquid phase filtered out flows smoothly into the first shell 1, and the separated liquid phase is collected centrally through the first shell 1.
[0042] In one embodiment, a plurality of through holes are also provided at the connection between the side wall and the bottom wall of the second shell 2 to reduce the residue of the filtered liquid in the second shell.
[0043] In one embodiment, a plurality of through holes are vertically opened in the limiting groove 6 to prevent the separated liquid phase from accumulating in the limiting groove 6 .
[0044] In one embodiment, an opening is provided on the top of the first shell 1 to facilitate the installation of the second shell 2; an opening is also provided on the top of the second shell 2 to facilitate the placement of the filter bag containing the solid-liquid mixture.
[0045] In one embodiment, the second shell 2 is cylindrical. This structure allows the filter bag to fit more closely to the inner wall of the second shell 2 than a rectangular body and other shapes, and the contact area is maximized, resulting in a better filter pressing effect.
[0046] In one embodiment, a drain port is provided at the bottom of the first shell 1, a drain pipe is installed on the drain port, and a switch valve is provided at the connection between the drain port and the drain pipe to prevent the separated liquid phase from directly flowing out of the drain port.
[0047] In one embodiment, a top cover is rotatably connected to the top of the first shell 1, and the shape of the top cover is adapted to the upper opening of the first shell 1. A spring buckle is provided on the side opposite to the rotational connection point between the top cover and the first shell 1, so as to achieve the fixing effect of the top cover when the filter press equipment is working.
