Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to an exhaust vent filter for a paint coating workshop. Background Art

[0002] A ship is a means of transport that can sail or anchor in waters for transportation or operations. It has different technical performance, equipment and structural types according to different usage requirements. When a ship is built, its exterior needs to be sprayed. Since harmful gases and dust will be generated during the painting process, they must be harmlessly treated. Therefore, a special paint painting workshop exhaust vent filter is required.

[0003] The traditional treatment process generally uses the workshop exhaust to pass the harmful gas through the exhaust duct, pre-filter, and then to the activated carbon adsorption catalytic combustion purification equipment for treatment before being discharged into the atmosphere. Under the traditional harmful gas treatment process, the pre-filter and activated carbon adsorption equipment will gradually reach saturation, making the filter equipment have a short service life and the filter material of the equipment needs to be replaced regularly. Not only is maintenance difficult, but the work intensity is also high, and the maintenance and replacement costs are high. For this reason, we provide a paint coating workshop exhaust filter. Utility Model Content

[0009] As a further improvement of the above solution, the top and bottom of the filter are rotatably connected with pulleys.

[0010] As a further improvement of the above solution, the sum of the areas of the two groups of vertical plates is consistent with the area of ​​the exhaust port.

[0011] As a further improvement of the above solution, the frame is provided with strip-shaped slots for the vertical plates to slide.

[0012] As a further improvement of the above solution, one end of the screw rod is coaxially fixedly connected to a handwheel.

[0013] As a further improvement of the above solution, guide blocks are symmetrically fixedly connected to the movable plate, and guide grooves are symmetrically opened on the outside of the exhaust duct and are slidably connected to the guide blocks.

[0014] As a further improvement of the above solution, the area of ​​the filter is consistent with the area of ​​the exhaust port.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model changes the traditional press-in structure into a frame push-pull structure, making it convenient to replace the filter material.

[0017] 2. The utility model adds activated carbon fiber felt to the traditional aerosol filtration, so that harmful gases can be adsorbed, thereby improving the purification effect.

[0020] 5. The utility model reduces the harmful gas dust residue entering the pre-filter and activated carbon adsorption catalytic equipment through the primary treatment of the exhaust filter, thereby increasing the operation cycle of the equipment and reducing maintenance costs.

[0021] 6. The utility model drives the moving plate to move by rotating the screw rod, utilizes the hinge effect between the moving plate and the slider and the connecting rod, and the sliding cooperation between the slider and the slide rod, so that the two groups of vertical plates can be driven to approach the filter, so that the replaced filter can be clamped to prevent it from automatically shifting in the frame and causing a gas escape gap, and after the filter is disassembled, the two groups of vertical plates are brought close to each other, so that the exhaust port can be blocked, thereby preventing unpurified gas from entering the exhaust duct, thereby preventing harmful gas and dust from escaping.

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] Embodiment 1:

[0029] Please combine Figure 1-3 The paint coating workshop exhaust vent filter of this embodiment includes:

[0030] An exhaust duct 1 is provided with an exhaust port on one side of the exhaust duct 1, a frame 2 is fixedly connected to the outside of the exhaust port, a filter 3 is inserted into the inner side of the frame 2, and the area of ​​the filter 3 is consistent with the area of ​​the exhaust port, so that the air can be thoroughly filtered;

[0031] The filter 3 includes a rear steel plate mesh 31, an activated carbon fiber felt 32 is arranged outside the rear steel plate mesh 31, a paint mist filter cotton 33 is arranged outside the activated carbon fiber felt 32, and a front steel plate mesh 34 is arranged outside the paint mist filter cotton 33;

[0032] The limit assembly includes two groups of vertical plates 101 symmetrically arranged and slidably connected to the frame, a horizontal bar 102 is fixedly connected to the vertical plate 101, a sliding rod 103 is fixedly connected to the outside of the exhaust duct 1, a slider 104 is symmetrically slidably connected to the outside of the slider 103 and fixedly connected to the horizontal bar 102, a screw rod 105 is rotatably connected to the outside of the exhaust duct 1, a movable plate 106 is threadedly connected to the outside of the screw rod 105, a connecting rod 107 is hinged between the movable plate 106 and the slider 104 through a hinge, and the sum of the areas of the two groups of vertical plates 101 Consistent with the area size of the exhaust port, the vertical plate 101 can seal the exhaust port after the filter 3 is removed to prevent harmful gases and dust from escaping. The frame 2 is provided with a strip groove for the vertical plate 101 to slide. One end of the screw rod 105 is coaxially fixedly connected to a hand wheel to facilitate the rotation of the screw rod 105. The movable plate 106 is symmetrically fixedly connected with a guide block 108. The outside of the exhaust duct 1 is symmetrically provided with guide grooves that are slidably connected to the guide block 108, which can play a certain guiding role in the horizontal movement of the movable plate 106.

[0033] The implementation principle of the exhaust vent filter of the paint coating workshop in the embodiment of the present application is as follows: when the filter 3 needs to be replaced, it only needs to be pulled out from the frame 2. When the used filter 3 is pulled out, the movable plate 106 is driven to move by rotating the screw rod 105. The hinge between the movable plate 106 and the slider 104 and the connecting rod 107, the sliding cooperation between the slider 104 and the sliding rod 103, and the sliding cooperation between the guide block 108 and the guide groove can drive the two sets of vertical plates 101 to approach each other, so that the exhaust vent can be blocked to prevent the unpurified air from directly entering the exhaust vent. The paint mist filter cotton 33 on the filter 3 can filter the paint mist and dust in the air, and the activated carbon fiber felt 32 can adsorb harmful gases in the air, thereby ensuring the air purification effect.

[0034] Embodiment 2:
