Description

Technical Field

[0001] This utility model relates to a dewatering filter press, and more particularly to a plate pulling mechanism for the dewatering filter press. Background Technology

[0002] A dewatering filter press is a core piece of equipment that achieves solid-liquid separation through mechanical pressure. It is widely used in industries such as wastewater treatment, mining, and chemicals. Its working principle is based on the pressure difference across the filter medium (such as filter cloth), which separates the liquid from the solid particles, forming a filter cake with low moisture content.

[0003] The plate-pulling mechanism of a filter press mainly consists of a frame, guide rails mounted on the frame, a plate-pulling trolley slidably mounted on the guide rails, and a transmission assembly mounted on the frame for driving the plate-pulling trolley. If the sliding resistance between the plate-pulling trolley and the guide rail is too high, it can easily cause the plate-pulling trolley to jam or even stop. Therefore, operators need to regularly lubricate and maintain this sliding part. Due to the design of the existing structure, the sliding part between the plate-pulling trolley and the guide rail is directly exposed to the external environment without any obstruction above it. This makes it easy for particulate impurities falling during the operation of the filter press to accumulate on the rails, thus interfering with the smooth sliding of the plate-pulling trolley. To address the above problems, this invention has emerged. Utility Model Content

[0004] The purpose of this invention is to provide a plate pulling mechanism for a dewatering filter press. This plate pulling mechanism can effectively reduce the accumulation of particulate impurities above the guide rail, thereby ensuring smooth sliding of the plate pulling trolley, ensuring normal operation of the filter press and extending its service life.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plate pulling mechanism for a dewatering filter press, comprising a frame, a plate pulling trolley, a guide rail mounted on the frame, and a transmission component mounted on the frame for driving the plate pulling trolley to move. An upper baffle for shielding the guide rail is provided above the guide rail, and the orthographic projection path of the guide rail in the vertical direction intersects the upper baffle. The plate pulling trolley includes a trolley body and a slide seat slidably disposed on the guide rail. The trolley body is located above the upper baffle, and the trolley body and the slide seat are connected by a bracket.

[0006] By adopting the above technical solution, an upper baffle is installed above the guide rail to shield the sliding parts between the guide rail and the slide block, reducing the accumulation of falling particulate impurities on the guide rail. This ensures smooth sliding of the plate-pulling trolley, guarantees the normal operation of the filter press, and extends its service life. A bracket is also installed to connect the trolley body to the slide block, ensuring the normal sliding of the plate-pulling trolley on the guide rail.

[0007] The upper baffle is further configured such that it is fixedly connected to the frame on the side near the frame, and extends along the opposite side of the frame and gradually slopes downward.

[0008] By adopting the above technical solution, the upper baffle is fixedly connected to the frame, so that the particulate impurities accumulated above the upper baffle will not fall into the space between the upper baffle and the frame. By setting the upper baffle as an inclined structure, the particulate impurities accumulated above the upper baffle can be discharged towards the side of the frame opposite to the baffle, thereby avoiding the excessive accumulation of particulate impurities from affecting the trolley body located above it.

[0009] The upper baffle is further configured such that a side baffle is connected to the side of the frame opposite to the upper baffle. The side baffle is located on the side of the frame opposite to the guide rail and extends along the length of the guide rail. The side baffle extends downward and intersects the orthographic projection path of the guide rail in the horizontal direction.

[0010] By adopting the above technical solution, the side baffle is used to further isolate the guide rail from the outside world, thereby further reducing the probability of particulate impurities entering the sliding part between the guide rail and the slide block and improving the quality of particulate impurity isolation.

[0011] The bracket is further configured such that it is connected to the side of the frame opposite to the slide, and the connection point between the bracket and the slide is located below the side baffle. The bracket is provided with a slag discharge hole at the position corresponding to the bottom of the side baffle.

[0012] By adopting the above technical solution, the slag discharge hole is designed to prevent particulate impurities that slide off the upper baffle from accumulating on the support, thereby reducing the probability of particulate impurities contacting the sliding parts between the guide rail and the slide block, and ensuring the effectiveness of the barrier.

[0013] The upper baffle is further configured such that an oil injection hole is provided, and a plurality of oil injection holes are arranged at intervals along the length of the guide rail, and each oil injection hole is provided with an opening and closing structure.

[0014] By adopting the above technical solution, the blocking effect of the upper baffle is retained through the opening and closing structure. By opening the opening and closing structure, oil can be injected into the guide rail through the oil injection hole, thereby improving the convenience of guide rail lubrication and maintenance operations.

[0015] The opening and closing structure is further configured to include a sealing plate and a magnetic sheet fixedly disposed on the sealing plate and magnetically attracted to the upper baffle.

[0016] By adopting the above technical solution, the magnetic sheet combined with the sealing plate structure can realize convenient opening and closing of the oil injection hole, which is convenient to operate and has lower production cost.

[0017] The transmission assembly is further configured to include two sprockets rotatably mounted on the frame, a transmission chain connecting the two sprockets and passing through the interior of the guide rail, and a drive motor driving one of the sprockets to rotate. The transmission chain is fixedly connected to the slide.

[0018] By adopting the above technical solution, the drive motor drives the sprocket to rotate, which in turn drives the slide block to slide along the guide rail via the transmission chain.

[0019] In summary, this utility model has the following beneficial effects: it can effectively reduce the accumulation of particulate impurities above the guide rail, thereby ensuring smooth sliding of the plate pulling trolley, ensuring the normal operation of the filter press and extending its service life.
