Description

Technical Field

[0001] This invention relates to the field of pathological sampling equipment technology, and in particular, to a pathological sampling table capable of diverting and collecting chemical waste. Background Technology

[0002] In pathology labs, sample processing with chemical reagents is standard procedure, with key components including xylene, formaldehyde, and alcohol. Currently, the sample collection process suffers from drawbacks such as complexity, time-consuming procedures, and the inability of the sampling station to effectively separate chemical waste from ordinary wastewater. This hinders the collection of chemical waste and the treatment of laboratory wastewater. If chemical waste and ordinary wastewater are collected together, the volume of wastewater collected is large, increasing subsequent wastewater treatment costs. However, treating chemical waste and ordinary wastewater together as ordinary wastewater does not comply with the management requirements for hazardous chemical wastewater. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a pathological sampling station capable of diverting and collecting chemical waste.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A pathological sampling table for diverting and collecting chemical waste includes a workbench with a tabletop; a water tank embedded in the tabletop, having a cleaning tank with an upper opening, wherein a partition is provided in the middle of the cleaning tank to divide it into a sewage tank and a wastewater tank, both of which have drain outlets at the bottom connected to drain pipes; a wastewater collection container is provided below the water tank on the workbench, and a connecting pipe head is provided at the end of the drain pipe at the bottom of the wastewater tank, with a connecting pipe head connected to the upper end of the wastewater collection container, the connecting pipe head and the connecting pipe head being connected and limited by a movable limiting member, the limiting member being movable to release the limiting of the connecting pipe head and the connecting pipe head; and a cover plate, slidingly mounted on the upper end of the water tank, having a first covered state and a second covered state, wherein the cover plate in the first covered state and the second covered state respectively covers the sewage tank and the wastewater tank.

[0006] Furthermore, it also includes a stabilizing structure connected to the cover plate, the stabilizing structure being used to cooperate with the partition to resist the sliding of the cover plate in the first covered state and the second covered state.

[0007] Furthermore, the bottom of the cover plate is provided with two spaced-apart lower extension plates, which are located on both sides of the partition plate; the stabilizing structure includes two elastic sheets spaced vertically, one end of each elastic sheet is connected to the lower extension plate, and the other end extends toward the partition plate, with the ends of the two elastic sheets away from the lower extension plates facing each other; the partition plate is provided with insertion holes, and when the cover plate is in the first or second covering state, the two elastic sheets on the corresponding lower extension plates are inserted into the insertion holes, and the two elastic sheets elastically deform and contact the top and bottom walls of the insertion holes respectively.

[0008] Furthermore, the lower end of the lower extension plate is provided with a bonding plate. When the cover plate is in the first covering state or the second covering state, the corresponding bonding plate is bonded to the partition plate to cover the insertion hole.

[0009] Furthermore, the upper end of the workbench is provided with a filter chamber, the bottom of the filter chamber is provided with air inlets, and a filter element is installed inside the filter chamber to filter the air that passes through the filter element.

[0010] Furthermore, an exhaust pipe is provided at the upper end of the filter chamber, and an air monitoring device is installed on the exhaust pipe to monitor air flow rate and air quality.

[0011] Furthermore, the filter chamber includes an installation cavity and a retracting cavity. The retracting cavity is located at the bottom of the installation cavity and retracts towards the installation cavity above. The filter element is installed in the installation cavity.

[0012] Furthermore, the mounting cavity has an opening on its front side, and a quick-release door is installed on the front side of the mounting cavity.

[0013] Furthermore, the upper edge of the cleaning tank is provided with a sinking groove, and the cover plate is embedded in the sinking groove and can move within the sinking groove.

[0014] Furthermore, the workbench is provided with a collection chamber below the water tank, and the wastewater collection container is placed in the collection chamber.

[0015] Furthermore, the connecting pipe head is provided with an insertion part for inserting into the connecting pipe head. The upper end of the insertion part is provided with a first skirt extending outward. The upper outer wall of the wastewater collection container is provided with an upwardly extending protrusion. The top of the protrusion is provided with a limiting block. The protrusion, the limiting block, and the upper outer wall of the wastewater collection container define a limiting groove with one side open. The first skirt is provided with a downwardly extending vertical arm. The lower end of the vertical arm is provided with a horizontally extending limiting claw. The limiting claw can rotate with the connecting pipe head and be inserted into the limiting groove. When the limiting claw is in contact with the bottom wall of the limiting block, the first skirt is in contact with the upper end of the connecting pipe head. The limiting member is a limiting strip hinged to the upper outer wall of the wastewater collection container. The limiting strip has a blocking state and an avoidance state. In the blocking state, the limiting strip is located outside the opening of the limiting groove to prevent the limiting claw from rotating out of the limiting groove. In the avoidance state, the limiting strip avoids the movement path of the limiting claw rotating out of the limiting groove.

[0018] The present invention has the following beneficial effects:

[0019] The design of the water tank separates the washing tank into a wastewater tank and a sludge / wastewater tank via a partition, allowing for the separate collection of chemical waste and general wastewater. This separate design prevents chemical waste from mixing with general wastewater, thereby reducing the cost of subsequent wastewater treatment. It also allows for the targeted collection of chemical waste, complying with the management requirements for hazardous chemical wastewater. Both the wastewater and sludge / wastewater tanks are equipped with drain outlets connected to drain pipes, enabling the separate discharge of chemical waste and general wastewater for convenient centralized treatment. The cover design makes the pathology sampling table more flexible in use. The cover has a first covering state and a second covering state, used to cover the wastewater tank and the sludge / wastewater tank respectively, preventing cross-contamination when using one tank and preventing chemical waste from entering the wastewater tank. By effectively separating chemical waste and general wastewater, the pollution of general wastewater by chemical waste is reduced, lowering the difficulty and cost of laboratory wastewater treatment. Simultaneously, it avoids potential safety hazards caused by the mixing of chemical waste and general wastewater, improving the overall safety and environmental performance of the laboratory.

[0043] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a pathological sampling table for diverting and collecting chemical waste, comprising a workbench 100, a water tank 200, and a cover plate 300.

[0044] The workbench 100 has a tabletop 110. A sink 200 is embedded in the tabletop 110. The sink 200 has a cleaning tank 210 with an upper opening. A partition 220 is provided in the middle of the cleaning tank 210 to divide the cleaning tank 210 into a sewage tank 211 and a wastewater tank 212. Both the sewage tank 211 and the wastewater tank 212 have drain outlets at the bottom, and the drain outlets are connected to drain pipes. A wastewater collection container 160 is provided below the sink 200 on the workbench 100. The end of the drain pipe at the bottom of the wastewater tank 212 is provided with a connecting pipe head 170. The upper end of the wastewater collection container 160 is connected to a connecting pipe head 180. The connecting pipe head 170 and the connecting pipe head 180 are connected and the connecting pipe head 170 and the connecting pipe head 180 are limited by a movable limiting member. The limiting member can move to release the limiting of the connecting pipe head 170 and the connecting pipe head 180. The limiting device can be used to achieve a stable connection between the connecting pipe head 170 and the connecting pipe head 180, thereby preventing sewage leakage and pollution of the working space environment; and when it is necessary to disconnect the connecting pipe head 170 and the connecting pipe head 180, the limiting device can be moved to release the restriction on the connecting pipe head 170 and the connecting pipe head 180. The operation is simple and convenient, facilitating the connection and disconnection of pipelines.

[0045] The cover plate 300 has a first covering state and a second covering state, in which the cover plate 300 covers the sewage tank 211 and the waste tank 212 respectively. The cover plate 300 is slidably mounted on the upper end of the tank 200 to realize the switching between the first covering state and the second covering state.

[0046] This invention provides a pathological sampling table for the separate collection of chemical waste. The design of the water tank 200 divides the washing tank 210 into a sewage tank 211 and a wastewater tank 212 via a partition 220, allowing chemical waste and ordinary sewage to be collected separately. This separate design avoids the mixing of chemical waste and ordinary sewage, thereby reducing the cost of subsequent wastewater treatment. It also allows for the targeted collection of chemical waste, meeting the management requirements for hazardous chemical wastewater. Both the sewage tank 211 and the wastewater tank 212 are equipped with drain outlets connected to drain pipes, allowing chemical waste and ordinary sewage to be discharged separately for convenient centralized treatment. The design of the cover plate 300 makes the pathological sampling table more flexible in use. The cover plate 300 has a first covering state and a second covering state, used to cover the sewage tank 211 and the wastewater tank 212 respectively, preventing cross-contamination when using one of the tanks and preventing chemical waste from entering the sewage tank 211. By effectively separating chemical waste and general wastewater, the pollution of general wastewater by chemical waste is reduced, thus lowering the difficulty and cost of laboratory wastewater treatment. At the same time, it avoids potential safety hazards caused by mixing chemical waste and general wastewater, improving the overall safety and environmental performance of the laboratory.

[0047] In some embodiments of the present invention, a stabilizing structure is also included. The stabilizing structure is connected to the cover plate 300 and is used to cooperate with the partition plate 220 so that the sliding of the cover plate 300 in the first covering state and the second covering state is resisted, thereby making the position of the cover plate 300 in the first covering state and the second covering state stable and not moving arbitrarily. Only when a person pushes to overcome the resistance and slides so that the stabilizing structure is disengaged from the partition plate 220 can it slide more easily. Thus, without affecting the normal state switching, the state of the first covering state and the second covering state are more stable, and the state can be maintained more stably.

[0048] Reference Figure 2 and Figure 3In some embodiments of the present invention, the bottom of the cover plate 300 is provided with two spaced-apart lower extension plates 310. Specifically, the sewage tank 211 and the waste tank 212 are spaced-apart from front to back, and the lower extension plates 310 are also spaced-apart from front to back. The two lower extension plates 310 are located on both sides of the partition plate 220. The stabilizing structure includes two elastic pieces 400 spaced-apart from top to bottom. One end of the elastic piece 400 is connected to the lower extension plate 310, and the other end extends toward the partition plate 220. The ends of the two elastic pieces 400 away from the lower extension plate 310 are arranged close to each other so that they can be smoothly inserted into the hole and reduce structural interference. The partition 220 is provided with an insertion hole 221. When the cover plate 300 is in the first covered state or the second covered state, the two elastic pieces 400 on the corresponding lower extension plate 310 are inserted into the insertion hole 221. The two elastic pieces 400 are elastically deformed and contact the top wall and bottom wall of the insertion hole 221 respectively, thereby forming contact pressure. This will apply frictional resistance to the elastic pieces 400 being pulled out of the insertion hole 221. Since the elastic pieces 400 are fixed together with the cover plate 300, they will apply resistance to the cover plate 300, thus stabilizing the cover plate 300.

[0049] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the lower end of the lower extension plate 310 is provided with a bonding plate 320. When the cover plate 300 is in a first covering state or a second covering state, the corresponding bonding plate 320 is bonded to the partition plate 220 to cover the insertion hole 221. This reduces the possibility of gas or liquid entering the groove on the other side of the partition plate 220 during use. Figure 4 and Figure 5 As shown, the cover plate 300 is in the first covered state, covering the sewage tank 211. The front bonding plate 320 is bonded to the partition plate 220, and the elastic piece 400 on the front lower extension plate 310 is inserted into the insertion hole 221. Figure 6 As shown, the cover plate 300 is in the second covering state, covering the waste tank 212. The backing plate 320 is attached to the partition plate 220, and the elastic piece 400 on the lower extension plate 310 is inserted into the insertion hole 221.

[0050] Reference Figure 3 In a further embodiment of the present invention, a filter chamber 120 is provided at the upper end of the workbench 100, and an air inlet 130 is distributed at the bottom of the filter chamber 120. A filter element 500 is installed in the filter chamber 120 to filter the air that passes through the filter element 500. The filter element 500 includes a frame and activated carbon installed in the frame, thereby adsorbing toxic and harmful gases.

[0051] Reference Figure 3In a further embodiment of the present invention, an exhaust pipe 140 is provided at the upper end of the filter chamber 120, and an air monitoring device is installed on the exhaust pipe 140 to monitor air flow rate and air quality. The air monitoring device includes a gas flow meter, sensors corresponding to various pollutants or toxic gases, etc. Thus, by detecting the air flow rate, it monitors whether the airflow capacity of the filter element 500 is reduced due to blockage, thereby affecting the absorption and filtration of toxic and harmful gases. The sensors corresponding to various pollutants or toxic gases determine whether the filtration effect of the filter element 500 meets the standards and whether it needs to be replaced, thereby effectively monitoring the air filtration effect and using this as a basis for determining when to replace the filter element 500.

[0052] Reference Figure 3 In a further embodiment of the present invention, the filter chamber 120 includes an installation cavity 121 and a collection cavity 122. The collection cavity 122 is located at the bottom of the installation cavity 121 and is drawn towards the installation cavity 121 above. The filter element 500 is installed in the installation cavity 121. The collection cavity 122 can effectively expand the gas collection range at the bottom and prevent toxic gases from not being effectively drawn in. The filter element 500 is installed in the installation cavity 121 so that the overall size of the filter element 500 does not need to be too large, thereby achieving centralized filtration.

[0053] Reference Figure 1 In a further embodiment of the present invention, the mounting cavity 121 has an opening on the front side, and a quick-release door 123 is installed on the front side of the mounting cavity 121 to facilitate the removal and replacement of the filter element 500. When removing the filter element 500, simply open the quick-release door 123, pull out the filter element 500, insert the new filter element 500, and then close the quick-release door 123. The quick-release door 123 can be hinged to the front end face of the filter chamber 120 housing, and the front side of the filter chamber 120 housing and the quick-release door 123 can be provided with corresponding magnetic suction components, so that when the quick-release door 123 is closed, it is tightly attached to the front side of the filter chamber 120 housing by magnetic suction, ensuring the stability of the closed state.

[0054] Reference Figure 2 In some embodiments of the present invention, a sinking groove 230 is provided on the upper edge of the cleaning tank 210, and the cover plate 300 is embedded in the sinking groove 230 and can move within the sinking groove 230. The sinking groove 230 is used to limit and guide the movement of the cover plate 300, making the sliding of the cover plate 300 more stable.

[0055] Reference Figure 3 In some embodiments of the present invention, the workbench 100 is provided with a collection chamber 150 below the water tank 200, and a wastewater collection container 160 is placed in the collection chamber 150. The wastewater collection container 160 can collect wastewater for convenient subsequent centralized treatment. It is understood that the drain pipe at the bottom of the sewage tank 211 can be connected to a normal sewage pipe.

[0056] Reference Figures 7 to 10 In a further embodiment of the present invention, the connecting pipe head 170 is provided with an insertion part 171 for inserting into the connecting pipe head 180. The insertion part 171 is inserted into the connecting pipe head 180 to realize the connection between the connecting pipe head 170 and the connecting pipe head 180 and the communication of the water passage. The upper end of the insertion part 171 is provided with an outwardly extending first skirt 172. The upper outer wall of the wastewater collection container 160 is provided with an upwardly extending protrusion 161. The top of the protrusion 161 is provided with a limiting block 162. The protrusion 161, the limiting block 162 and the upper outer wall of the wastewater collection container 160 define a limiting groove 163 with one side open. The first skirt 172 is provided with a downwardly extending vertical arm 173. The lower end of the vertical arm 173 is provided with a horizontally extending limiting claw 174. The limiting claw 174 can be rotated with the connecting pipe head 170 and inserted into the limiting groove 163. The insertion part 171 is inserted into the connecting pipe head 180, which can reduce the exposure of wastewater to the outside and its evaporation. The limiting claw 174 is embedded in the limiting groove 163 to limit the connection head 170 and improve the stability of the connection head 170 and the connecting head 180; when the limiting claw 174 is in contact with the bottom wall of the limiting block 162, the first skirt 172 is in contact with the upper end of the connecting head 180. The limiting component is a limiting strip 190 hinged to the upper outer wall of the wastewater collection container 160. The limiting strip 190 has a blocking state and an avoidance state. In the blocking state, the limiting strip 190 is located outside the opening of the limiting groove 163 to prevent the limiting claw 174 from rotating out of the limiting groove 163, thereby limiting the connection between the connecting pipe head and the connecting pipe head, improving the connection stability between the connecting pipe head and the connecting pipe head, and preventing easy separation that could lead to sewage leakage. In the avoidance state, the limiting strip 190 avoids the movement path of the limiting claw 174 rotating out of the limiting groove 163, thereby releasing the limiting of the connecting pipe head and the connecting pipe head. When disassembling and separating them, it is only necessary to rotate the connecting pipe head 170 to make the limiting claw 174 rotate out of the limiting groove 163 and then pull out the insertion part 171 to separate the connecting pipe head 170 and the connecting pipe head 180. During installation, simply insert the insertion part 171 into the connecting pipe head 180 until the first skirt 172 is in contact with the upper end of the connecting pipe head 180. At this time, the limiting claw 174 and the limiting groove 163 are offset but at the same height. Then, rotate the connecting pipe head 170 as a whole so that the limiting claw 174 is embedded in the limiting groove 163. Then, rotate the limiting strip 190 from the avoidance state around the hinge point to the blocking state. When it is necessary to remove and move the wastewater collection container 160, simply reverse the above installation steps. Installation and disassembly do not require disassembling the fasteners, and the operation is simple and convenient.

[0057] Reference Figures 7 to 10In a further embodiment of the present invention, a sealing cap 600 is also included. The sealing cap 600 is hinged to the wastewater collection container 160 via a hinge shaft. The sealing cap 600 has a covered state and a flow state. To reduce interference and maximize the sealing effect of the sealing cap 600 in the covered state, the sealing cap 600 is provided with a frustum 610 to be embedded in the outlet at the lower end of the connecting pipe head 180 in the covered state, thereby achieving a better sealing effect. It is understood that the conical surface of the frustum 610 can be wrapped with a rubber sleeve. The sealing cap 600 in the covered state covers the outlet at the lower end of the connecting pipe head 180, so that when the connecting pipe head 170 is separated from the connecting pipe head 180, the sealing cap 600 in the covered state can effectively reduce the evaporation and leakage of wastewater in the wastewater collection container 160 during the handling of the wastewater collection container 160, thereby reducing external environmental pollution and affecting the health of relevant personnel. The sealing cap 600 in the flow state at least partially opens the outlet at the lower end of the connecting pipe 180, allowing the liquid in the connecting pipe 170 to flow smoothly into the wastewater collection container 160. A torsion spring is installed on the hinge shaft, which drives the sealing cap 600 in the flow state to move towards the covered state, so that when the connecting pipe 170 is separated from the connecting pipe 180, the sealing cap 600 can return to and maintain the covered state under the action of the torsion spring. The lower end of the insertion part 171 is provided with a narrowing head 175, and the insertion part 171 is provided with a transition slope 176 extending obliquely towards the narrowing head 175. The transition slope 176 is provided with a downwardly extending push rod 177, which can be inserted into the connecting pipe 180 along with the insertion part 171 and push the sealed cap 600 in the covered state to the flow state. When the first skirt 172 is in contact with the upper end of the connecting pipe 180, the sealing cap 600 in the flow state is horizontally offset from the lower outlet of the narrowing head 175. When the first skirt 172 is in contact with the upper end of the connecting pipe 180, the connecting pipe 170 and the connecting pipe 180 are already inserted into place. At this time, the limiting claw 174 is embedded in the limiting groove 163, and the limiting strip 190 reaches the blocking state. At this time, the projection areas of the sealing cover 600 and the lower end outlet of the narrowing head 175 on the horizontal plane are offset (do not intersect). At this time, the waste liquid discharged from the lower end outlet of the narrowing head 175 falls on the sealing cover 600 as little as possible, so that when the sealing cover 600 returns to the covered state, there is no waste liquid residue on its upper surface, avoiding the evaporation and dispersion of waste liquid residue on the upper surface, which would affect the working environment.

[0058] Reference Figures 7 to 10In a further embodiment of the present invention, the upper end of the connector 180 is provided with a second skirt 181, and the second skirt 181 is provided with a clearance opening 182. The vertical arm 173 can rotate within the clearance opening 182, thereby limiting the range of motion of the vertical arm 173 and preventing the limiting claw 174 from being difficult to install in place due to an excessive range of motion of the vertical arm 173. When the vertical arm 173 is respectively attached to the two end walls of the clearance opening 182, the limiting claw 174 is respectively disengaged from or embedded in the limiting groove 163. That is, when the vertical arm 173 is attached to one end wall of the clearance opening 182, the limiting claw 174 is disengaged from the limiting groove 163, and when the vertical arm 173 is attached to the other end wall of the clearance opening 182, the limiting claw 174 is embedded in the limiting groove 163, thereby facilitating the determination of whether the limiting claw 174 is installed in place. In order to ensure that the limiting claw 174 can reach the same height as the limiting groove 163 smoothly when it moves downward, the upper end of the limiting block 162 is provided with a chamfer 164. The chamfer 164 guides the pressing limiting claw 174 to the opening side of the limiting groove 163.

[0059] Of course, in some other embodiments, the top of the wastewater collection container 160 can be simply provided with an insertion port, and the sewage pipe at the bottom of the wastewater tank 212 can be inserted into the wastewater collection container 160 through the insertion port.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
