[0016] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] Example 1 Please see Figures 1 to 6 The present invention preferably provides a technical solution: a solid-liquid separation device for water pollution control, comprising: a base 111, a housing 112 fixedly assembled with the base 111; and a partition 116 inclinedly disposed in the middle of the housing 112, used to divide the housing 112 into a solid recovery chamber and a liquid recovery chamber distributed on the left and right, wherein the liquid recovery chamber is sequentially equipped with a first solid-liquid separation component and a second solid-liquid separation component from top to bottom, used for primary solid-liquid separation and secondary solid-liquid separation of pollutants, respectively; and a hook conveying component disposed in the housing 112 and distributed along the inclined direction of the partition 116, wherein the bottom end of the hook conveying component is connected to the second solid-liquid separation component and used to transfer pollutants after secondary solid-liquid separation; and a pressure plate assembly disposed in the housing 112 and acting on the upper part of the hook conveying component, used for tertiary solid-liquid separation of pollutants on the hook conveying component.

[0018] like Figure 4 , 5As shown, the box 112 is divided into a solid recovery chamber and a liquid recovery chamber distributed on the left and right by a central partition 116 in the middle. The liquid recovery chamber is equipped with a first solid-liquid separation component and a second solid-liquid separation component from top to bottom, which are used for primary solid-liquid separation and secondary solid-liquid separation of pollutants. The hooked conveyor assembly located in the middle of the housing 112, such as Figure 4 , 5 As shown, its bottom end connects to the second solid-liquid separation component and is used to transfer pollutants after the secondary solid-liquid separation. Its top end interacts with the pressure plate component installed on the upper part of the box 112 to achieve further solid-liquid separation of the pollutants. When the pollutants are transferred through the first solid-liquid separation component and the second solid-liquid separation component and followed by the hook conveyor component, the pollutants can undergo the first, second and third stage solid-liquid separation processes in sequence with the cooperation of the pressure plate component and the hook conveyor component. This step-by-step purification process can not only efficiently improve the solid-liquid separation efficiency of the pollutants, but also significantly improve the separation quality.

[0019] Furthermore, the first solid-liquid separation assembly includes support blocks 126 symmetrically fixed to the upper part of the liquid recovery chamber of the housing 112, each support block 126 being provided with a second spring 127; and a separation frame 128 fixed to the top of the two second springs 127 and extending out of the liquid recovery chamber, the bottom of the separation frame 128 being provided with several through grooves 129 for primary solid-liquid separation of pollutants.

[0020] The first solid-liquid separation component is described here. Figure 1 , 2 As shown in Figures 3 and 5, the two support blocks 126, the two second springs 127, and the separation frame 128 are assembled and fixedly connected from bottom to top. The design of the top of the separation frame 128 extending out of the upper edge of the box 112 facilitates the feeding of pollutants. When the pollutants are placed inside the separation frame 128, the through groove 129 opened at the bottom of the separation frame 128 can perform primary solid-liquid separation on the pollutants. This process can pre-treat the pollutants, i.e., coarse separation, to remove large suspended and floating objects, such as leaves, plastics, fibers, and gravel. And the design of preprocessing: First, it can protect downstream equipment, as large solid debris may entangle, block, or wear down downstream structures, leading to frequent downtime for maintenance and increasing maintenance costs.

[0021] Secondly, it reduces the load on subsequent processing by removing some solids in advance, significantly reducing the burden on secondary and tertiary solid-liquid separation, allowing subsequent structures to be more specialized in processing finer particles.

[0022] Furthermore, the second solid-liquid separation assembly includes two side plates fixed to the lower part of the liquid recovery chamber where the housing 112 is located; and a separation plate 117 inclinedly fixed to the opposite side of the two side plates, wherein the bottom end of the separation plate 117 is connected to the hook conveying assembly, and several through holes 118 opened thereon are used for secondary solid-liquid separation of pollutants.

[0023] like Figure 4 , 5 As shown, the fixed and inclined separation plate 117 is placed below the separation frame 128, and its bottom end is connected to the hook conveying assembly. When the pollutants after coarse separation by the first solid-liquid separation assembly fall onto the surface of the separation plate 117, the several through holes 118 opened on the separation plate 117 can remove most of the solids in the sewage, realizing the secondary separation process.

[0024] Example 2 In another embodiment of this utility model, the hook conveying assembly includes a transmission roller 113 rotatably mounted on the upper and lower parts of the liquid recovery chamber where the housing 112 is located, a transmission belt 114 sleeved and mounted with the two transmission rollers 113, and hooks 115 equidistantly mounted on the outer periphery of the transmission belt 114. The hooks 115 distributed at the bottom end of the transmission belt 114 are tangent to the arc-shaped groove opened at the end of the side plate and the bottom end of the separation plate 117, while the hooks 115 distributed at the top end are tangent to the pressure plate assembly.

[0025] This implementation example Figure 4 As shown, the transmission belt 114, which is sleeved on the two transmission rollers 113, has hooks 115 evenly spaced on its outer circumference. Several hooks 115 distributed at the bottom end of the transmission belt 114 are tangent to the arc-shaped groove at the end of the side plate and the bottom end of the separation plate 117, while several hooks 115 distributed at the top end are tangent to the pressure plate assembly. When several hooks 115... Figure 4 When rotated counterclockwise, the contaminants on the surface of the separation plate 117 can move toward the pressure plate assembly under the action of the hook 115, realizing a three-stage separation process. The contaminants that have undergone three-stage separation further follow the hook conveyor assembly until they pass over the partition plate 116, thus realizing the process of the contaminants falling into the solid recovery chamber and being collected.

[0026] Furthermore, the pressure plate assembly includes a fixing plate 119 fixed to the upper part of the housing 112, and a cam transmission structure and a groove structure 120 respectively disposed on both sides of the fixing plate 119. The groove structure 120 includes a limiting slide groove 1201 whose groove diameter decreases progressively in the opposite direction of the transmission belt 114's running direction, and a limiting slider 1203 and a fixing block 1202 disposed within the limiting slide groove 1201. The limiting slider 1203 is slidably installed inside the limiting slide groove 1201, and the fixing block 1202 is disposed at the end of the limiting slide groove 1201 away from the cam transmission structure. A first spring 1204 is connected between 1202 and the limiting slider 1203; it also includes a transmission plate 121 fixed to the limiting slider 1203, and the transmission plate 121 includes a connecting plate 1211, an arc plate 1213 disposed at one end of the connecting plate 1211 and in transmission contact with the cam transmission structure, and pressure strips 213 disposed inside the connecting plate 1211 and the arc plate 1213 and connected one-to-one with the hooks 115. When the cam transmission structure is running, several pressure strips 213 approach several hooks 115 and squeeze the contaminants on the hook conveying assembly to achieve three-stage solid-liquid separation of contaminants.

[0027] like Figure 5 , 5 As shown in Figure 6, the groove structure 120 and the cam transmission structure are distributed at both ends of the fixed plate 119. The limiting slide 1201 containing the groove structure 120 has a limiting slider 1203 and a fixing block 1202 as shown in Figure 6. Figure 6 The components are distributed left and right, and a first spring 1204 connects the limiting slider 1203 and the fixing block 1202. Because the arc-shaped plate 1213 where the transmission plate 121 is located is in transmission contact with the cam transmission structure, and the connecting plate 1211 is fixed to the limiting slider 1203, the cam transmission structure pushes the transmission plate 121 and the limiting slider 1203 within the limiting groove 1201. Figure 4 , 6 When moving to the left or right, the pressure strips 213 provided on the inner side of the transmission plate 121 can move away from or closer to the hooks 115 distributed at the upper end of the transmission belt 114, so as to squeeze the pollutants between them and realize the third solid-liquid separation process of the pollutants.

[0028] Furthermore, the cam transmission structure includes a mounting block 122 fixed on the side of the fixed plate 119 away from the groove structure 120, a first transmission shaft 130 rotatably mounted on the mounting block 122; and a cam body 123 fixed on the first transmission shaft 130, wherein the convex end of the cam body 123 is in transmission contact with the arc plate 1213.

[0029] like Figure 6 As shown, when the first drive shaft 130 rotates, the cam body 123 can push the transmission plate 121 to move towards the second solid-liquid separation assembly, that is, as Figure 4 , 6 The pressure bar 213 on the inner side of the transmission plate 121 moves closer to the hook 115 to achieve a three-stage solid-liquid separation process; conversely, the pressure bar 213 moves away from the hook 115.

[0030] Furthermore, a first push rod 124 is fixed to the side of the transmission plate 121 near the second solid-liquid separation assembly, with one end of the first push rod 124 away from the transmission plate 121 contacting the surface of the separation plate 117; and a second push rod 125 is fixed in the middle of the first push rod 124 and in contact with the bottom of the separation frame 128.

[0031] As can be seen from the above, such as Figure 4 , 5 As shown, the ends of the first push rod 124 and the second push rod 125 are in contact with the separation plate 117 and the separation frame 128, respectively. When the transmission plate 121 moves inside the tank structure 120, the first push rod 124 and the second push rod 125 can strike the separation plate 117 and the separation frame 128, respectively, to accelerate the separation speed of the second solid-liquid separation component and the first solid-liquid separation component.

[0032] Furthermore, a meshing drive assembly is also provided on the outer side of the base 111 for synchronous driving of the cam transmission structure and the hook conveyor assembly; the meshing drive assembly includes a first drive gear 131 and a second drive gear 132 that mesh with each other, wherein the first drive gear 131 is fixed to one end of the first transmission shaft 130 away from the cam body 123; and a second transmission shaft 135 rotatably mounted on one side of the base 111, with one end of the second transmission shaft 135 fixed to the transmission roller 113 placed on the upper position, and the other end used for the fixed assembly of the second drive gear 132; it also includes a mounting bracket 133 fixed on the outer side of the base 111, and the output shaft of the motor 134 mounted on the mounting bracket 133 is fixed to the second drive gear 132.

[0033] It is known that the first drive shaft 130 and the second drive shaft 135 are used to connect the cam body 123 and the first drive gear 131, respectively, and the upper drive roller 113 and the second drive gear 132. Simultaneously, the first drive gear 131 and the second drive gear 132 mesh with each other. Figure 1 , 2 As shown in Figure 3, when the motor 134 drives the second drive gear 132 to rotate, the synchronous operation of the hook conveyor assembly and the pressure plate assembly can be realized. It is worth noting that the hook conveyor assembly and the pressure plate assembly move synchronously, but there is a certain distance between them, so they will not affect each other's movement.

[0034] Furthermore, the base 111 is also provided with a door structure 211 and a drain port 212 at the bottom of the solid recovery chamber and the liquid recovery chamber, respectively. It is worth noting that the door structure 211 is a mature existing technology, and its specific structure will not be described in detail. Under the action of the door structure 211 and the drain port 212, the sewage discharge of the solid recovery chamber and the liquid discharge of the liquid recovery chamber can be realized.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0036] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
