Description

Technical Field

[0001] This utility model relates to the field of photovoltaic wastewater treatment technology, and in particular to a device for preparing high-efficiency defluorination seed crystals for photovoltaic industry wastewater. Background Technology

[0002] Wastewater generated during photovoltaic production needs to be treated before discharge, and this wastewater contains fluoride ions. Fluoride-removing seed crystals can be added to the wastewater at a calculated dosage, and the fluoride remover can be evenly dispersed in the wastewater using mechanical stirring or other methods to ensure full contact with the fluoride ions. The fluoride remover then reacts fully with the fluoride ions to form a precipitate or be adsorbed.

[0003] Fluoride removal seed crystals can be selected from calcium salts, aluminum salts, iron salts, and composite seed crystals. Novel composite seed crystals, such as resins and modified zeolites containing specific functional groups, remove fluoride ions through multiple processes including ion exchange, adsorption, and complexation. For example, in LA-modified zeolite, the ammonium cations can enhance adsorption and flocculation, while the acid anions can complex with metal ions. After reacting with a lanthanum source, they form a cross-linked network structure with lanthanum, which is beneficial for fluoride removal from water. The preparation of LA-modified zeolite involves crushing and sieving, modification reaction, washing, and drying.

[0004] A search of Chinese patents for a jaw crusher, publication number CN 220194956 U, reveals the following: a feeding device with a feeding pipe; a crusher body with its inlet connected to the outlet of the feeding pipe; and a foreign object sorting wheel rotatably connected to the inner wall of the crusher body and located at its inlet. The sorting wheel includes multiple gripping claws spaced apart along its outer circumference, all facing the same direction for hooking and removing foreign objects. This application provides a jaw crusher that, through the inclusion of a foreign object sorting wheel, a metal sensor, and an electromagnetic suction device, effectively prevents foreign objects from entering the crusher body, thus avoiding jamming.

[0005] When a jaw crusher crushes zeolite, the crushed material falls from the bottom of the frame onto the conveyor belt below and flows to the screening area. However, some of the fallen material spills off the sides of the conveyor belt, causing material loss and increasing the labor required for subsequent cleaning. Therefore, there is a need to provide a high-efficiency defluorination seed preparation device for photovoltaic industry wastewater to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency defluorination seed preparation device for photovoltaic industry wastewater, so as to solve the problem mentioned in the background art, where the broken material falls from the lower end of the frame onto the conveyor belt below and flows to the screening area through the conveyor belt. Some of the fallen broken material will spill from both sides of the conveyor belt, causing material loss and increasing the labor problem of subsequent cleaning.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a device for preparing high-efficiency fluoride removal seed crystals from photovoltaic industry wastewater, comprising:

[0009] A jaw crusher, comprising a frame and a crushing chamber, wherein the crushing chamber is fixed to the upper end of the frame;

[0010] The anti-spraying component includes a support rod, a movable groove, a slider, a connecting rod, and a baffle. The support rod is fixed to the lower end of the inner side of the frame, the movable groove is opened in the middle of the lower end of the support rod, the slider is inserted into the movable groove, the connecting rod is fixed to the lower end of the slider, and the baffle is fixed to the lower end of the connecting rod.

[0011] Furthermore, the anti-spray assembly also includes a square through hole, a groove, and a first locking rod. The square through hole is opened on the side of the movable groove, the groove is opened on the side of the slider, and the first locking rod is inserted into the square through hole and screwed into the groove.

[0012] Furthermore, the anti-spray assembly also includes a reinforcing plate, which is fixed to the side of the baffle.

[0013] Furthermore, the jaw crusher also includes a movable jaw and a fixed jaw. The movable jaw is movably connected inside the crushing chamber, and the fixed jaw is fixed inside the crushing chamber. The movable jaw and the fixed jaw are movably connected.

[0014] Furthermore, the baffle is tilted downwards and located at the lower ends of the moving jaw and the fixed jaw.

[0015] Furthermore, it also includes a connecting assembly, which includes a U-shaped frame, a through hole, and a second locking rod. The U-shaped frame is fixed to the lower inner sides of both sides of the frame, the through hole is opened on the side of the U-shaped frame, and the second locking rod is screwed into the through hole.

[0016] Furthermore, the support rod is inserted into the U-shaped frame, and the second locking rod is pressed against the side of the support rod.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] I. This utility model, through the setting of the anti-spillage component, moves the slider along the movable groove inside the support rod, and the first locking rod moves along the square through hole, driving the baffle below the connecting rod to move to the appropriate position, tightening the first locking rod in the groove. When the broken material falls from under the moving jaw and the fixed jaw, the broken material in the middle falls onto the conveyor belt, and the broken material on both sides falls onto the baffle, and then slides off the baffle onto the conveyor belt. This setting can prevent broken material from falling from both sides of the conveyor belt and reduce material loss.

[0019] Second, this utility model, through the set connection component, allows the second locking rod in the round hole to be loosened when the equipment is not in use, and the support rod to be pulled out of the U-shaped frame for unified storage. This setting can reduce the footprint of the equipment and prevent the support rod from being exposed, thus avoiding affecting the movement of people. Attached Figure Description

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-5 As shown, this embodiment is a device for preparing high-efficiency defluorination seed crystals from photovoltaic industry wastewater, comprising:

[0032] The jaw crusher includes a frame 10 and a crushing chamber 11, with the crushing chamber 11 fixed to the upper end of the frame 10.

[0033] The jaw crusher also includes a movable jaw 12 and a fixed jaw 13. The movable jaw 12 is movably connected inside the crushing chamber 11, and the fixed jaw 13 is fixed inside the crushing chamber 11. The movable jaw 12 and the fixed jaw 13 are movably connected.

[0034] The frame 10 provides support, and the crushing chamber 11 is used to crush materials. A motor is installed inside to control the rotation of the pulley, which in turn drives the eccentric shaft to rotate. The eccentric shaft drives the moving jaw 12 to move, so that the moving jaw 12 hits the fixed jaw 13 to crush the material. A liner is fixed on the side of the moving jaw 12 and the fixed jaw 13 that are close to each other. In addition to transmitting force, the liner mainly serves as a safety device. When non-crushable materials enter the crushing chamber, the fixed jaw 13 and the moving jaw 12 of the crusher will be subjected to great force. The toggle plate can be broken or bent in advance to protect other parts of the machine.

[0035] The anti-spraying component includes a support rod 20, a movable groove 21, a slider 23, a connecting rod 25, and a baffle 26. The support rod 20 is fixed to the lower end of the inner side of the frame 10. The movable groove 21 is opened in the middle of the lower end of the support rod 20. The slider 23 is inserted into the movable groove 21. The connecting rod 25 is fixed to the lower end of the slider 23. The baffle 26 is fixed to the lower end of the connecting rod 25.

[0036] The anti-splash assembly also includes a square through hole 22, a groove 24 and a first locking rod 28. The square through hole 22 is opened on the side of the movable groove 21, the groove 24 is opened on the side of the slider 23, and the first locking rod 28 is inserted into the square through hole 22 and screwed into the groove 24.

[0037] The anti-spray assembly also includes a reinforcing plate 27, which is fixed to the side of the baffle 26;

[0038] The baffle 26 is tilted downward and located at the lower end of the movable jaw 12 and the fixed jaw 13;

[0039] The support rod 20 provides support, and the movable groove 21 facilitates the adjustment of the slider 23 position. The position of the baffle 26 is adjustable through the support rod 20, movable groove 21, and slider 23 to accommodate conveyor belts of different widths. The square through hole 22, groove 24, and first locking rod 28 are used to lock the slider 23. The slider 23 and connecting rod 25 serve as a connection. The baffle 26 serves as a block and guide. The reinforcing plate 27 can improve the strength of the baffle 26.

[0040] Working principle:

[0041] The slider 23 moves along the movable groove 21 inside the support rod 20, and the first locking rod 28 moves along the square through hole 22, driving the baffle 26 below the connecting rod 25 to move to the appropriate position. The first locking rod 28 in the groove 24 is tightened. When the broken material falls from below the moving jaw 12 and the fixed jaw 13, the broken material in the middle falls onto the conveyor belt, and the broken material on both sides falls onto the baffle 26, and then slides off the baffle 26 onto the conveyor belt.

[0042] This step prevents debris from falling from both sides of the conveyor belt, reducing material loss.

[0043] Please see Figure 4-5 This embodiment, based on the above embodiments, further includes:

[0044] The connecting assembly includes a U-shaped frame 30, a through hole 31, and a second locking rod 32. The U-shaped frame 30 is fixed to the lower inner sides of both sides of the frame 10. The through hole 31 is opened on the side of the U-shaped frame 30, and the second locking rod 32 is screwed into the through hole 31.

[0045] The support rod 20 is inserted into the U-shaped frame 30, and the second locking rod 32 is pressed against the side of the support rod 20;

[0046] The U-shaped frame 30 serves as a support and limiter, while the through hole 31 and the second locking rod 32 are used to fix the support rod 20.

[0047] Working principle:

[0048] When the crusher is needed, insert the support rod 20 into the U-shaped frame 30, tighten the second locking rod 32 in the through hole 31, and adjust the position of the baffle 26. After production is completed, pull the support rod 20 out of the U-shaped frame 30 and store it together.

[0049] This step reduces the footprint of the equipment and prevents the support rod 20 from being exposed, thus avoiding obstruction of personnel movement.
