[0022] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Photocatalytic oxidation purification equipment, such as Figures 1 to 5As shown, it includes a body 1 and two catalytic plates 2 installed at both ends of the body 1. Both ends of the body 1 are provided with slots 3, and the two slots 3 are located on the same side of the body 1. The catalytic plate 2 is installed into the body 1 after passing through the slots 3. One end of the catalytic plate 2 is fixed with a closing block 4 by a bolt 9. The closing block 4 is sleeved with a sealing ring 5 for resisting the slot wall of the slot 3. Four extrusion blocks 6 for extruding the sealing ring 5 are slidably arranged on the closing block 4. The sealing ring 5 is also sleeved with four extrusion blocks 6. By arranging the closing block 4 on the catalytic plate 2, the slot 3 can be closed, and the sealing ring 5 is sleeved on the closing block 4. At the same time, the extrusion block 6 for extruding the sealing ring 5 is slidably arranged on the closing block 4, thereby improving the sealing performance of the catalytic plate 2 when it is installed into the body 1. The sealing ring 5 is made of silicone rubber. By using silicone rubber to make the sealing ring 5, the sealing ring 5 has good ozone resistance.

[0024] like Figure 2 , Figure 3 and Figure 5 As shown, the closing block 4 is provided with a control block 7, the control block 7 is in a prism shape, the cross section of the extrusion block 6 is trapezoidal, the inclined surfaces of the control block 7 and the extrusion block 6 fit together, the thickness of the control block 7 is less than the thickness of the extrusion block 6, and the extrusion block 6 contacts the sealing ring 5. By arranging the control block 7 on the closing block 4, the control block 7 is in a prism shape, and the cross section of the extrusion block 6 is trapezoidal. Since the inclined surfaces of the control block 7 and the extrusion block 6 fit together, and the thickness of the control block 7 is less than the thickness of the extrusion block 6, when the control block 7 moves toward the closing block 4, the control block 7 drives the extrusion block 6 away from the control block 7. The control block 7 moves in the direction of the sealing ring 5, and the extrusion block 6 contacts the sealing ring 5, so that the extrusion block 6 squeezes the sealing ring 5. Two through holes 8 are provided on the control block 7, and bolts 9 are passed through the through holes 8. The closing block 4 is provided with threaded holes 10 corresponding to the positions of the through holes 8. The bolts 9 pass through the through holes 8 and are threadedly connected with the threaded holes 10. When the bolts 9 rotate, the bolts 9 enter the threaded holes 10 or move away from the threaded holes 10, so that the bolts 9 drive the control block 7 to move, so that the control block 7 can be close to or away from the closing block 4, so that the extrusion block 6 squeezes the sealing ring 5, and a sealing effect is achieved.

[0025] like Figure 2 and Figure 3As shown, six sliding grooves 11 are provided on the closing block 4, and a sliding bar 12 is integrally formed on the extrusion block 6. The extrusion block 6 is divided into two transverse extrusion blocks 6 and two longitudinal extrusion blocks 6. The length of the transverse extrusion block 6 is smaller than that of the longitudinal extrusion block 6. A sliding bar 12 is provided on the transverse extrusion block 6, and two sliding bars 12 are provided on the longitudinal extrusion block 6. The sliding bar 12 slides in the sliding groove 11. By arranging the sliding groove 11 on the closing block 4 and the sliding bar 12 on the extrusion block 6, the sliding bar 12 slides in the sliding groove, thereby realizing the sliding connection of the extrusion block 6 to the closing block 4. The cross-section of the sliding groove 11 is T-shaped, the cross-section of the sliding bar 12 is the same as that of the sliding groove 11, and the length of the sliding bar 12 is smaller than that of the sliding groove 11, so that the sliding bar 12 keeps sliding in the sliding groove 11.

[0026] like Figure 4 As shown, two positioning grooves 13 for accommodating the catalytic plate 2 are provided on the inner wall of the body 1, and the positioning grooves 13 correspond to the positions of the slots 3. By providing the positioning grooves 13 on the inner wall of the body 1, the positioning grooves 13 accommodate the end of the catalytic plate 2 away from the closing block 4, so that after the catalytic plate 2 is installed in the body 1, the positioning grooves 13 have a positioning effect on the catalytic plate 2. The cross-section of the positioning grooves 13 is trapezoidal, and the bottom area of ​​the positioning grooves 13 is smaller than the area of ​​the opening of the positioning grooves 13. A clamping portion 14 is provided at the end of the catalytic plate 2 away from the closing block 4, and the clamping portion 14 is fitted and clamped with the positioning grooves 13, so as to facilitate the clamping portion 14 to enter the positioning grooves 13.

[0027] Working process: When installing the catalytic plate 2, the operator first picks up the catalytic plate 2 and aligns the end of the catalytic plate 2 provided with the clamping portion 14 with the slot 3, and then inserts the catalytic plate 2 into the body 1. Since the positioning slot 13 is provided on the inner wall of the body 1, the cross-sections of the positioning slot 13 and the clamping portion 14 are both trapezoidal, and the bottom area of ​​the positioning slot 13 is smaller than the opening area of ​​the positioning slot 13. Therefore, when the catalytic plate 2 contacts the inner wall of the body 1, the clamping portion 14 can enter the positioning slot 13 for positioning. When the clamping portion 14 completely enters the positioning slot 13, the sealing block 4 is used to close the slot 3, and the sealing ring 5 on the closing block 4 contacts the slot wall of the slot 3. Then the operator rotates the bolt 9. During this process, the bolt 9 is rotated into the threaded hole 10. At this time, the control block 7 is driven by the bolt 9 to approach the closing block 4. Since the control block 7 is in a prism shape and the cross-section of the extrusion block 6 is trapezoidal, the control block 7 contacts the inclined surface of the extrusion block 6. Therefore, when the control block 7 moves, the control block 7 squeezes the extrusion block 6 and drives the extrusion block 6 to squeeze the sealing ring 5. After the sealing ring 5 is squeezed, the sealing effect of the catalytic plate 2 when it is installed in the body 1 is improved.

[0028] When disassembling the catalytic plate 2, the operator rotates the bolt 9 in the opposite direction. During this process, the control block 7 moves away from the closing block 4. At this time, the extrusion block 6 stops squeezing the sealing ring 5, thereby reducing the friction between the sealing ring 5 and the groove wall of the groove 3, making it easier to remove the catalytic plate 2. Then the operator pulls out the catalytic plate 2. During this process, the clamping portion 14 moves away from the positioning groove 13 and slides out of the groove 3.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
