Abstract
Description
Technical Field
[0001] This utility model relates to the field of occupational disease prevention equipment, specifically to a surround-type exhaust workbench. Background Technology
[0002] The lens cleaning process involved in the production and manufacturing of optical lenses is a manual operation. The cleaning solvent used is a mixed alcohol. The general operating station is a regular workbench without ventilation facilities. In order to ensure product quality, the working environment is mostly a clean room.
[0003] The mixed alcohols are highly volatile, and the workbench lacks exhaust ventilation. During on-site operations, the volatilized mixed alcohol gases may endanger the occupational health of workers. Furthermore, the work environment is a cleanroom with an internal air conditioning system and no full-room exhaust ventilation, causing the mixed alcohol gases to accumulate within the facility and exacerbating the health hazards to workers.
[0004] The lens cleaning process requires high ambient light levels and a relatively constant temperature and humidity in the factory. Therefore, high-powered fume hoods are not suitable as local exhaust ventilation systems. Furthermore, for ease of operation, workers are not accustomed to using enclosed or partially sealed exhaust ventilation systems. Utility Model Content
[0005] This application provides a surround-type exhaust workbench that solves the problems mentioned in the prior art.
[0006] The technical problem solved by this utility model can be achieved by the following technical solution:
[0007] A surround-type exhaust workbench, comprising:
[0008] Workbench;
[0009] A bracket that is detachably connected to the lower surface of the worktable;
[0010] A flow equalization and purification device, which is detachably connected to a bracket;
[0011] The exhaust section is detachably connected to the workbench and located on the periphery of the workbench. The exhaust section is connected to the flow equalization and purification device and has several exhaust holes.
[0012] Furthermore, the exhaust unit includes a rear exhaust module, a front exhaust module, and a pair of side exhaust modules. The rear exhaust module is detachably connected to the upper rear surface of the workbench, the front exhaust module is detachably connected to the lower front surface of the workbench, and the pair of side exhaust modules are detachably connected to the lower left and right sides of the workbench, respectively. The rear exhaust module, the front exhaust module, and the pair of side exhaust modules are all parallel to the upper surface of the workbench. The rear exhaust module, the front exhaust module, and the pair of side exhaust modules are all connected to the flow equalization and purification device. Each of the rear exhaust module, the front exhaust module, and the side exhaust modules has several exhaust holes at equal intervals. The exhaust holes of the rear exhaust module and the front exhaust module are located on the front side of the rear exhaust module and the front exhaust module, respectively. The exhaust holes of the pair of side exhaust modules are located on the side of the side exhaust module opposite to the workbench.
[0013] Furthermore, the exhaust unit includes a guide cover with an opening on one side fixed on the exhaust holes of the rear exhaust module, the front exhaust module, and the side exhaust module. The guide cover of the rear exhaust module has an opening facing downwards, while the guide covers of the front exhaust module and the side exhaust module have openings facing upwards.
[0014] Furthermore, the flow equalization purification device includes a housing, an exhaust pipe, and several air inlet pipes. The housing is detachably connected to the lower surface of the workbench. An air outlet is opened on one side of the housing. The exhaust pipe is fixed to the air outlet and is connected to the housing. Several air inlet pipes are respectively connected between the rear exhaust module, the front exhaust module, and the side exhaust module and the housing, and the rear exhaust module, the front exhaust module, and the side exhaust module are connected to the housing.
[0015] Furthermore, a filter box is detachably connected to one side of the housing, and the filter box communicates with the inside of the housing. The exhaust pipe is detachably connected to the other side of the filter box and communicates with the inside of the filter box.
[0016] Furthermore, an activated carbon module is detachably connected inside the filter box.
[0017] Furthermore, the rear exhaust module, front exhaust module, and side exhaust module are connected to the housing by at least one air intake pipe.
[0018] Furthermore, the specifications of the workbench are as follows: length 1400mm-1600mm, width 700mm-800mm, height 700mm-800mm.
[0019] The beneficial effects of this utility model are:
[0020] By employing a rear exhaust module, a front exhaust module, and a pair of side exhaust modules, a surround exhaust design is formed, facilitating the nearby discharge of harmful gases.
[0021] Because it uses a rear exhaust module, a front exhaust module, and a pair of side exhaust modules, its specifications can be adapted to the size of the existing workbench, without changing the existing factory equipment layout or the operating habits of the workers.
[0022] The use of a filter box effectively solves the problem of purifying harmful gases. The activated carbon inside the filter box then filters the gases to meet emission requirements. Attached Figure Description
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Figure 2 This is a schematic diagram of the shell structure of this utility model.

[0027] Example 1:
[0028] Reference Figure 1-2 This is a structural schematic diagram of Embodiment 1 of the present invention, a surround-type exhaust workbench, comprising:
[0029] Workbench 1;
[0030] Support 2, which is detachably connected to the lower surface of workbench 1;
[0031] A flow equalization and purification device, which is detachably connected to a bracket;
[0032] The exhaust section is detachably connected to the workbench 1 and located on the periphery of the workbench 1. The exhaust section is connected to the flow equalization and purification device and has several exhaust holes.
[0033] The specifications of the workbench 1 are as follows: length 1400mm-1600mm, width 700mm-800mm, height 700mm-800mm.
[0034] In actual use: Workbench 1 is supported by bracket 2 to make it horizontal. A seat is placed in front of workbench 1, and the worker sits on the seat with their hands on the upper surface of workbench 1. At the same time, the flow equalization and purification device is connected to the negative pressure system of the workshop and the negative pressure system is turned on. The negative pressure system generates suction inside the flow equalization and purification device and at the same time generates suction in the exhaust fan. The exhaust fan creates suction in the direction of the exhaust fan on both sides, front and back of workbench 1. At the same time, air is drawn in through the exhaust holes, forming an air curtain surrounding workbench 1. The air curtain at the front of workbench 1 isolates the air flow between the worker and workbench 1. Thus, the gas generated by the operation on workbench 1 is drawn in by the exhaust fan and enters the negative pressure system through the flow equalization and purification device.
[0035] To maintain the operators' operating habits, the specifications of the exhaust workbench are basically the same as those of the regular workbench, with the preferred specifications being: 1500mm in length, 750mm in width, and 780mm in height.
[0036] Example 2:
[0037] Reference Figure 1-2 The difference in this embodiment is that the exhaust unit includes a rear exhaust module 3, a front exhaust module 4, and a pair of side exhaust modules 5. The rear exhaust module 3 is detachably connected to the upper rear surface of the workbench 1, the front exhaust module 4 is detachably connected to the lower front surface of the workbench 1, and the pair of side exhaust modules 5 are detachably connected to the lower left and right sides of the workbench 1, respectively. The rear exhaust module 3, the front exhaust module 4, and the pair of side exhaust modules 5 are all parallel to the upper surface of the workbench. The rear exhaust module 3, the front exhaust module 4, and the pair of side exhaust modules 5 are respectively connected to the flow equalization purification device. The rear exhaust module 3, the front exhaust module 4, and the side exhaust modules 5 are all equidistantly provided with a number of exhaust holes. The exhaust holes of the rear exhaust module 3 and the front exhaust module 4 are located on the front side of the rear exhaust module 3 and the front exhaust module 4, and the exhaust holes of the pair of side exhaust modules 5 are respectively located on the side of the side exhaust module 5 opposite to the workbench 1.
[0038] In actual use: To ensure the ventilation effect, a rear exhaust module 3, a front exhaust module 4, and a side exhaust module 5 are used instead of a single, interconnected structure. The main function of the rear exhaust module 3 is to adsorb and form an air curtain on the upper surface of the workbench 1. The side exhaust module 5 mainly adsorbs and forms an air curtain on the space on both sides of the workbench 1, preventing the gas from escaping through the sides. The front exhaust module 4 mainly adsorbs and forms an air curtain on the space in front of the workbench 1, preventing the gas on the workbench 1 from escaping forward and causing the workers to come into contact with the gas.
[0039] The optimized settings allow for raising the rear exhaust module 3, creating a larger adsorption surface. Multiple rear exhaust modules 3 can also be used in parallel to prevent a reduction in adsorption efficiency.
[0040] The rear exhaust module 3, the front exhaust module 4, and the side exhaust module 5 are all box-type structures.
[0041] Example 3:
[0042] Reference Figure 1-2 The difference in this embodiment is that: the exhaust section includes a guide cover 6 with an opening on one side fixed on the exhaust holes of the rear exhaust module 3, the front exhaust module 4 and the side exhaust module 5. The guide cover 6 of the rear exhaust module 3 has an opening facing downward, while the guide covers of the front exhaust module 4 and the side exhaust module 5 have openings facing upward.
[0043] In actual use: The guide cover 6 can control the adsorption direction of the exhaust hole, so that the air curtain formed by the front exhaust module 4 and the rear exhaust module 3 is vertically upward, while the air intake direction of the rear exhaust module 3 is downward, so that most of the gas on the working surface will not escape upward.
[0044] In this embodiment, the guide cover 6 can be integrally stamped into the exhaust module, so that the top of the guide cover 6 is perpendicularly stamped onto one side of the exhaust module, thus completing the forming of the exhaust hole and the guide cover 6 in one step.
[0045] Example 4:
[0046] Reference Figure 1-2 The difference in this embodiment is that the flow equalization purification device includes a housing 7, an exhaust pipe 8 and several air inlet pipes 11. The housing 7 is detachably connected to the lower surface of the workbench 1. An air outlet is opened on one side of the housing 7. The exhaust pipe 8 is fixed on the air outlet and is connected to the housing 7. Several air inlet pipes 11 are respectively connected between the rear exhaust module 3, the front exhaust module 4 and the side exhaust module 5 and the housing 7, and the rear exhaust module 3, the front exhaust module 4 and the side exhaust module 5 are connected to the housing 7.
[0047] In actual use: the exhaust pipe 8 is connected to the negative pressure system. The negative pressure system creates a negative pressure inside the housing 7 through the exhaust pipe 8. The housing 7 is connected to the rear exhaust module 3, the front exhaust module 4, and the side exhaust module 5 through the air intake pipe 11, which creates a negative pressure inside the rear exhaust module 3, the front exhaust module 4, and the side exhaust module 5, thereby generating suction in the exhaust holes. The housing 7 is connected to the rear exhaust module 3, the front exhaust module 4, and the side exhaust module 5 through the air intake pipe 11. Therefore, it is not necessary for each exhaust module to be connected to the negative pressure system separately, which facilitates centralized management.
[0048] Example 5:
[0049] Reference Figure 1-2The difference in this embodiment is that: a filter box 10 is detachably connected to one side of the housing 7, the filter box 10 is connected to the inside of the housing 7, and the exhaust pipe 8 is detachably connected to the other side of the filter box 10, and the exhaust pipe 8 is connected to the inside of the filter box 10.
[0050] In actual use: the filter box 10 can perform primary filtration of the gas, reduce the filtration pressure of the filter system in the negative pressure system, and meet the emission requirements.
[0051] Example 6:
[0052] Reference Figure 2 The difference in this embodiment is that an activated carbon module 9 is detachably connected inside the filter box 10.
[0053] In actual use: the activated carbon module 9 can purify the gas to meet emission requirements, and the cost is relatively cheap.
[0054] Example 7:
[0055] Reference Figure 1-2 The difference in this embodiment is that at least one air intake pipe 11 is connected between the rear exhaust module 3, the front exhaust module 4 and the side exhaust module 5 and the housing 7.
[0056] In actual use: Multiple air inlet pipes 11 can be connected between the housing 7 and the rear exhaust module 3, the front exhaust module 4 and the side exhaust module 5, thereby improving the adsorption effect and preventing the problem of insufficient suction in some parts of the rear exhaust module 3, the front exhaust module 4 and the side exhaust module 5.
[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes are within the protection scope of the technology.
