Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment and relates to a grinding machine filtering water tank. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. When the abrasive tool grinds the workpiece, it generates heat, which increases the temperature of the abrasive tool and the workpiece. When the heat cannot dissipate quickly, the temperature of the abrasive tool and the workpiece will be too high, which will affect the processing quality of the workpiece. Therefore, a cooling system is set on the grinder.

[0003] The cooling system includes a water tank, a delivery pipe and a spray pipe. A water pump is installed in the water tank. One end of the delivery pipe is connected to the water pump, and the other end of the delivery pipe is connected to the spray pipe. When the coolant cools the workpiece, the grinding chips on the workpiece will be mixed into the coolant. Therefore, a filter is often provided in the water tank to filter the grinding chips. For example, a grinder water tank device disclosed in Chinese patent literature [publication number: CN 106808368 A] includes an outer water tank cover, an upper buffer tank and a lower movable filter tank. The upper buffer tank is arranged at the upper right corner of the water tank cover and forms a cube with the water tank cover. The lower movable filter tank is arranged on the lower left side of the upper buffer tank. A guide water pipe is arranged on the left side of the upper buffer tank. The guide water pipe is suspended above the lower movable filter tank. A filter screen partition is arranged inside the lower movable filter tank. The filter screen partition is also called a filter plate. An anti-overflow port is also arranged on the upper side of the filter screen partition, and a plurality of rollers are also arranged at the bottom of the lower movable filter tank. A water receiving trough is also arranged above the water tank device, and a water outlet pipe connecting the water tank device and the water receiving trough is arranged at the bottom of the water receiving trough. A filter tank upper cover is also arranged on the lower movable filter tank to prevent water from splashing out during movement.

[0004] Since the filter partition is arranged inside the lower movable filter tank, when taking out the filter partition for cleaning, it is necessary to first disassemble the water tank cover and then open the filter tank cover before the filter partition can be taken out. After the cleaning is completed, after the filter partition is installed and fixed, it is also necessary to reinstall the filter tank cover and the water tank cover, which makes it inconvenient to disassemble and assemble the filter partition for cleaning. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art, and proposes a grinding machine filtering water tank, and solves the technical problem of how to make the filter plate in the water tank easy to disassemble and assemble.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A grinding machine filter water tank comprises a box body, wherein the box body comprises a buffer chamber and a filter chamber, a filter plate is fixed in the filter chamber, a cover plate is arranged at the upper end of the filter chamber, and the buffer chamber and the filter chamber are arranged in a left-right direction, a plug hole is provided on the cover plate, the filter plate is inserted in the plug hole and can be inserted into and taken out of the filter chamber through the plug hole, and the upper end of the filter plate extends out of the plug hole and is provided with a gripping portion.

[0008] Since the buffer chamber and the filter chamber are arranged in the left-right direction, the existence of the buffer chamber will not interfere with the disassembly and assembly of the plug plate. When the filter plate needs to be taken out for cleaning after the grinder has been working for a period of time, just hold the grip part with your hand to pull the filter plate out through the jack. After cleaning, just hold the grip part and reinsert the filter plate through the jack. The filter plate is easy to disassemble and assemble when cleaning.

[0009] In the above-mentioned grinding machine filter water tank, the gripping portion protrudes from the side of the filter plate, so that it is convenient for fingers to grasp the gripping portion to form a fulcrum, making it easy to disassemble and assemble the filter plate.

[0010] In the above-mentioned grinding machine filter water tank, the filter chamber is vertically provided with guide rails corresponding to the two sides of the filter plate, and the two sides of the filter plate are respectively inserted into the corresponding guide rails. The guide rails have a positioning function, so that the filter plate is stably installed in the filter chamber, and the guide rails also have a guiding function, so that the filter plate is easy to insert and remove.

[0011] In the above-mentioned grinder filter water tank, the buffer chamber is located on the left side of the filter chamber, and the filter chamber is divided into a first filter chamber, a second filter chamber and a third filter chamber which are connected in sequence along the front-to-back direction. The buffer chamber is connected to the first filter chamber, and the filter plate is arranged in the first filter chamber near the buffer chamber, and the filter plate is arranged in the second filter chamber near the first filter chamber, and the filter plate is arranged in the third filter chamber near the second filter chamber, and a water pump is fixed in the third filter chamber away from the second filter chamber.

[0012] The coolant flows from the grinder into the buffer chamber, then passes through the first filter chamber, the second filter chamber, and the third filter chamber in sequence, and is then pumped back to the processing position of the grinder by the water pump. The three filter chambers and multiple filter plates can improve the filtering effect and prevent grinding chips from entering the water pump and affecting the performance of the water pump.

[0013] In the above-mentioned grinding machine filter water tank, the filter plates in the second filter chamber and the filter plates in the third filter chamber are staggered in the left-right direction. This can increase the flow path of the coolant in the second filter chamber, increase the sedimentation time of the coolant in the second filter chamber, and help improve the sedimentation filtration effect.

[0014] In the above-mentioned grinding machine filter water tank, there are two filter plates in the second filter chamber and they are arranged in the front-to-back direction, and there are two filter plates in the third filter chamber and they are arranged in the front-to-back direction, which can improve the filtering effect.

[0015] In the above-mentioned grinding machine filter water tank, a detachable water receiving funnel is fixedly connected to the upper end of the buffer chamber, and a removable buffer inner box is placed below the water receiving funnel in the buffer chamber.

[0016] The coolant flows from the grinder into the water receiving funnel, and then into the buffer inner box from the water receiving funnel. Both the water receiving funnel and the buffer inner box have a buffering effect, so that the coolant is buffered before entering the filter chamber. The buffer inner box has a sedimentation effect, so that part of the coarse particles of grinding debris are precipitated in the buffer inner box. When the buffer inner box needs to be cleaned, the water receiving funnel is removed, and then the buffer inner box is taken out for separate cleaning, which is convenient for cleaning.

[0017] In the above-mentioned grinder filter water tank, the buffer chamber is divided into a first buffer chamber, a second buffer chamber and a third buffer chamber which are connected in sequence, the third buffer chamber is connected to the first filter chamber, the second buffer chamber is located behind the third buffer chamber, the second buffer chamber and the third buffer chamber are located between the first buffer chamber and the filter chamber, and the buffer inner box is placed in the first buffer chamber. The provision of three buffer chambers can increase the buffer path, and increase the buffering and sedimentation effects. In addition, the position layout of the three buffer chambers and the three filter chambers can also make the overall volume of the water tank small, save the space occupied by the water tank in the grinder, and reduce costs.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The filter plate can be inserted and removed through the jack on the cover plate, which is convenient for disassembly and cleaning. A separate buffer inner box is provided for easy removal and cleaning. The position layout of the three buffer chambers and three filter chambers can not only improve the filtering effect of the water tank, but also save the space occupied by the water tank in the grinder and reduce costs.
