Description

Technical Field

[0001] This utility model relates to the field of adsorption and purification technology, and in particular to a tribasic lead sulfate adsorption and purification device. Background Technology

[0002] The tribasic lead sulfate adsorption purification device is mainly used to treat wastewater containing pollutants such as heavy metal ions and organic matter. The core of this device lies in using tribasic lead sulfate as the adsorbent material, removing harmful substances from the water through physical and chemical adsorption, thereby purifying the water. Tribasic lead sulfate (Pb₃SO₄₂OH₂) possesses high chemical and thermal stability, maintaining good adsorption performance over a wide pH range. This material has a strong adsorption capacity for various heavy metal ions such as copper, zinc, cadmium, and lead, and can also adsorb some organic pollutants. Through selective adsorption, tribasic lead sulfate can effectively reduce the concentration of harmful substances in water and improve water quality.

[0003] The basic structure of the device includes an adsorption bed filled with tribasic lead sulfate particles. The liquid to be treated enters the adsorption bed from the top and exits from the bottom after passing through it. This design utilizes gravity to ensure that the liquid passes evenly through the adsorbent material, guaranteeing sufficient contact time between the liquid and the adsorbent material and improving adsorption efficiency. The adsorption bed design also includes a pretreatment unit to remove large particulate impurities, prevent clogging of the adsorbent material, and extend its service life.

[0004] In existing technologies, liquids tend to accumulate locally before entering the treatment medium, which can easily lead to localized overload or underutilization of the treatment medium. Furthermore, the liquid can easily form short-circuit flow paths within the treatment medium, affecting the adsorption effect. Therefore, there is a need to propose a tribasic lead sulfate adsorption and purification device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as easy local accumulation, easy local overload or insufficient utilization of the treatment medium, and easy formation of short-circuit flow paths in the treatment medium, which affects the adsorption effect. Therefore, a tribasic lead sulfate adsorption and purification device is proposed.

[0006] Ensure the liquid is evenly distributed before entering the treatment medium to avoid localized overload or underutilization of the treatment medium. Prevent the liquid from forming short-circuit flow paths in the treatment medium and ensure that all liquids have sufficient contact with the treatment medium.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A tribasic lead sulfate adsorption and purification device includes a primary filter box and a filter box. The primary filter box contains a primary filtration mechanism. A pair of interconnected spray pipes are movably installed within the filter box. A circulation drive mechanism is located at the top of the filter box to drive the spray pipes in a cyclical manner. A spray mechanism is located between the primary filter box and the filter box. An adsorption box is fixedly installed within the filter box. The circulation drive mechanism includes a mounting frame. The spray pipes are fixedly installed within the mounting frame. A movable groove is formed at the center of the top of the filter box. A T-shaped connecting block is fixedly installed at the center of the top of the mounting frame. The vertical section of the T-shaped connecting block is slidably disposed within the movable groove. A fixed rack is fixedly installed at the top of the horizontal section of the T-shaped connecting block. A drive assembly is located at the top of the filter box to drive the fixed rack to reciprocate.

[0009] Used to drive the spray pipe to move back and forth in a cycle. The drive component drives the fixed rack to move back and forth, so that the spray pipe moves back and forth in a cycle, ensuring that the liquid can be evenly distributed before entering the treatment medium, avoiding local overload or underutilization of the treatment medium, and preventing the liquid from forming a short-circuit flow path in the treatment medium, ensuring that all liquid can fully contact the treatment medium.

[0010] Preferably, the drive assembly includes a fixed frame fixedly installed at the top of the filter box, a first rotating shaft rotatably installed at the center of the top of the fixed frame, and a pair of second rotating shafts symmetrically arranged on both sides of the first rotating shaft rotatably installed at the top of the fixed frame. The first rotating shaft is coaxially fixedly connected to a drive gear, and the second rotating shaft is coaxially fixedly connected to a driven gear. Both driven gears mesh with the drive gear.

[0011] Each of the second rotating shafts is coaxially fixedly connected with a sector gear. The sector gear meshes with the snap teeth on the outer wall of the fixed rack, and when one sector gear meshes with the fixed rack, the other sector gear separates from the fixed rack.

[0012] The fixed rack is used to drive the reciprocating movement of the fixed rack. The first rotating shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the second rotating shaft to rotate, and the second rotating shaft drives the sector gear to rotate. When one sector gear meshes with the fixed rack, the other sector gear disengages from the fixed rack, at which point the fixed rack moves. When the sector gear disengages from the fixed rack, the other sector gear meshes with the fixed rack, at which point the fixed rack moves in the opposite direction. Thus, as the first rotating shaft rotates, the fixed rack performs a cyclic reciprocating motion.

[0013] Preferably, a plurality of rotating balls are rotatably mounted at the bottom of the horizontal section of the T-shaped connecting block, the outer side wall of the rotating balls is in contact with the top of the filter box, and a drive motor is fixedly mounted at the top of the fixing frame, and the output shaft of the drive motor is coaxially and fixedly connected to the first rotating shaft.

[0014] Several T-shaped limiting blocks are fixedly installed at the top of the mounting frame, and T-shaped limiting grooves are symmetrically opened at the top of the filter box. The T-shaped limiting blocks are slidably arranged in the T-shaped limiting grooves.

[0015] To ensure smooth movement of the main spray pipe, the fixed rack moves in a cyclical motion, driving the mounting bracket to move in a cyclical motion via the T-shaped connecting block. At this time, the T-shaped limiting block slides in the T-shaped limiting groove, and the rotating ball rotates on the top surface of the filter box, ensuring smooth movement of the main spray pipe.

[0016] Preferably, the primary filtration mechanism includes a primary filter plate slidably disposed in the primary filter box, the top of the primary filter box is connected to a liquid inlet, and the primary filter plate is inclined from the liquid inlet to the bottom of the primary filter box.

[0017] Used for pretreatment of liquids to remove large particulate impurities, prevent clogging of adsorbent materials, and extend their service life.

[0018] Preferably, the spraying mechanism includes a liquid pump fixedly installed on the outer wall of the filter box. The liquid pump is connected to a liquid pumping pipe and a liquid delivery pipe. The other end of the liquid pumping pipe extends to the bottom of the primary filter box, and the other end of the liquid delivery pipe extends into the filter box and is connected to the main spraying pipe. The bottom end of the main spraying pipe is connected to several spray heads.

[0019] Used to transport pretreated liquid into the main spray pipe. Start the liquid pump, and the pretreated liquid enters the main spray pipe through the liquid pump and the liquid delivery pipe, and is then sprayed out through the spray head.

[0020] This utility model has the following beneficial effects:

[0021] 1. By setting up a circulating drive mechanism, the drive component drives the fixed rack to move back and forth, so that the spray main pipe moves back and forth in a circular manner, ensuring that the liquid can be evenly distributed before entering the treatment medium, avoiding local overload or underutilization of the treatment medium, and preventing the liquid from forming a short-circuit flow path in the treatment medium, ensuring that all liquids can fully contact the treatment medium.

[0022] 2. By setting up a drive assembly, the drive motor drives the first rotating shaft to rotate, the first rotating shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the second rotating shaft to rotate, and the second rotating shaft drives the sector gear to rotate. When one sector gear meshes with the fixed rack, the other sector gear disengages from the fixed rack, at which point the fixed rack moves. When the sector gear disengages from the fixed rack, the other sector gear meshes with the fixed rack, at which point the fixed rack moves in the opposite direction. Thus, as the first rotating shaft rotates, the fixed rack performs cyclic reciprocating motion. Attached Figure Description
